Abstract Six face- and back-mounted chromogenic print samples (each 120 × 160 cm) and one pre-damaged original photograph (120 × 120 cm) were exposed to alternating temperature conditions. Cold storage was set at 8 °C with a slightly fluctuating relative humidity at an average of 55 % in a cooling chamber; room temperature storage occurred at 19 to 27 °C depending on the prevailing weather conditions. The samples were exposed alternatingly to these setups in a 24-hour rotation over five weeks to assess the effect of strong and rapid fluctuations on the stability of the composite. After about one week under the extreme, stress-intensive testing conditions, irreversible deformation, and a local loss of translucency occurred. Further local delamination was observed on the pre-damaged original artwork. Exceeding the dew point temperature, which occurred in our experimental setup and should be avoided, resulted in condensation on the acrylic surface and led to extensive streaks and, in combination with the electrostatic charge, to extreme dust deposits. These findings suggest that cold storage cannot be recommended for face- and back-mounted chromogenic prints.

Abstract: In India, 16 % of the total produce that is being wasted every year is horticultural produce. The underlying cause of post-harvest loss in the country is the lack of infrastructure for short-term storage, particularly at the farm level, concentration of cold storage in some states, lack of trained staff to operate cold storage systems, as well as the lack of intermediate processing in the production catchments. In the country, there is a 90% deficit of cold storage facilities. This shortage is compounded by misallocation. The cold storages are concentrated in a few states while vast expanses of the nation are left underserved. The nation’s 60% cold storages are located in just 4 states – Uttar Pradesh, Gujarat, West Bengal and Punjab. Out of the 30.11 million metric tonnes of cold storage facility provided by the 6,300 cold chain warehouses in the country, Tamil Nadu has access to only 0.0239. In India, milk, meat and poultry are prioritized for cold chain transport because they are highly perishable; meaning a lack of temperature-controlled transit would cause a near absence of these products in the market. Consequently, when horticultural produce is shipped, it is often sent in unrefrigerated, overstocked trucks that either rot the food in transit or damage it severely due to poor packaging. Furthermore, the Indian government estimates that 80-90% of the remaining cold storage in the country is used to house potatoes leaving disproportionate hordes of other perishable foods like fresh fruits unguarded.

Agriculture is the leading occupation for the people of the Jharkhand. State has potential to produce horticulture product and this type of product like fruits and vegetables need cold storage industry because It plays a significant role for the agricultural sector where various items such as Vegetables, fruits and meat etc.is stored where temperature is maintained, so as to protect them from getting spoiled and there by extend their preservation period with the help of precision instruments. Cold storages are an acute technology to keep perishable items safe. It is also an industry to increase revenue by protecting and reducing the wastage of fruits & vegetables. Cold storage is a place where an item is needed can be taken anytime and can be made available to consumers very easily. Due to non-availability of space in the existing cold storage units, farmers are facing hardships to store their produced. The purpose of the study to analyze the current scenario of cold storage capacity in Jharkhand. It has been seen that there is a wide gap in availability of cold storages and agriculture produce to the markets. There are only 25 storage which has 80625MT capacity in Jharkhand. So, the urgent need for affordable, reliable, and sustainable expansion of cold storage infrastructure is crucial to boost agriculture's economic contribution. Farmers need the right financing and storage for the right price, enabling them to directly connect with multiple markets and maximize socio-economic impact.

Background. L-asparaginase is effective in treating canine and feline lymphoma, however chemotherapy poses a significant financial cost to veterinary clients, limiting therapy for many pets. Single dose vials result in significant drug wastage, and drug shortages limit consistent availability for pets.Hypothesis.E. coli-derived asparaginase retains enzymatic and antineoplastic activity in canine and feline lymphoma cells after cold storage.Methods.E. coli-derived asparaginase was cold-stored: refrigeration (7–14 days) and freezing (14 days–six months, one to three freeze/thaw cycles). Enzymatic activity of asparaginase was measured via a modified asparagine assay. Effects of cold-stored asparaginase on cell proliferation and cytotoxicity were measured in feline (MYA-1, F1B) and canine (17–71, OSW) lymphoma cells.Results. Cold-storedE. coli-derived asparaginase retains antineoplastic activity in all four cell lines tested. Cold-storedE. coli-derived L-asparaginase depletes asparagine and retains enzymatic activity. Duration of refrigeration, duration of freezing, and number of freeze-thaw cycles have minimal effect on asparaginase enzyme activity.Conclusions and Clinical Importance. This study establishes a scientific basis for long-term cold storage of reconstitutedE. coli-derived asparaginase that may result in better utilization of limited drug resources and improve financial feasibility ofE. coli-derived asparaginase as a therapeutic option for pets with lymphoma.

<p><strong>Abstract.</strong> The deficiency in post-harvest infrastructure leads to loss of agricultural produce which in turn affects farmer’s income and food security. So, there is a need to improve post-harvest infrastructure in the country. Potato is a major horticultural crop requiring cold storage facility. This study was carried out for Bihar state of India, which has the least ratio of storage capacity to potato production in comparison to other states. An approach has been developed to identify the suitable locations for cold storages using geospatial technology to increase accessibility to cold storage facilities. Temporal variations in vegetation profiles were used to generate crop maps and from this crop area proportions were calculated at village level. These proportions were used to identify significant village clusters contributing to horticulture production. From this priority villages were identified. These priority villages were assigned to nearest major settlement which will be the sites for positioning new cold storage facility. The approach developed in this study has identified 63 locations in 17 districts for developing new cold storage facility. The proposed new locations for cold storages will reduce the distance to nearest cold storage for 14244 villages and this reduction in distance will be more than 8 kms for 9774 villages. Thus, the study validated the role of Remote Sensing and GIS for post-harvest infrastructure planning.</p>

This thesis concerns cold energy storage (CES) technology. Such a technology produces cold energy by consuming electricity in a refrigerator and stores cold energy in an eutectic phase change material (PCM) in a temperature range of (TPCM is the PCM storage temperature and Ta is the environmental temperature), resulting in a cold exergy efficiency less than 100%. The stored cold energy can be either directly extracted by a cold discharge process or utilized through a Rankine cycle at peak hours for electricity generation. The aim of the research is to study fundamental aspects and address the scientific and technological challenges associated with the CES technology. Methods for storing high grade, high energy density and temperature-adaptive cold energy are to be developed. Another objective is to develop innovative solutions for enhancing charge/ discharge processes. Particular attention is paid to the use of a prototype CO2 based CES system to investigate the feasibility of CES technology for small scale systems. In this work, a criteria for PCM selection for high grade and high energy density cold storage is established. For enhancing charging/ discharging rate of a PCM device, metal foams are embedded in PCM to form a PCM composite. Parametric study on the CES system is done based on a CO2 Rankine cycle for achieving an optimal cold storage efficiency. Investigations have been carried out on the performance of a small scale CES system. These include CES with an open and a close Rankine cycle and a piston based engine for cold to power conversion in the cycle. A method for improving grade of stored cold energy is using eutectic salt-water solutions for forming a binary/ ternary cold storage system, by which the eutectic temperature is lowered. PCMs with lower freezing temperature and smaller molecular weight are selected as components in the binary/ ternary system. However, due to the potential issue of compatibility of PCM molecular structures, it is critical to select PCMs which have comparable melting temperatures and compatible molecular structures. PCM composite is formed by embedding metal foams in PCM solutions. Cold discharging rate, defined as the power transfer of cold energy per unit time during the discharge process, is greatly affected by thermal diffusivity and thermal conductivity of the PCM composite. Combined effect of cold radiation and convection is to be considered for assessing the value of cold discharging rate, which becomes more significant for large PCM capsules under low PCM temperatures and low Reynolds number (Re). Cold utilisation in a CES system using Rankine cycles is theoretically studied. Storage efficiency of the CES system is a round trip efficiency of electricity, which is defined as ratio of output electricity to the input electricity. A storage efficiency as high as 43.9% has been shown to be possible for the CES system. However, the storage efficiency is generally between 30%~40% in consideration of the actual efficiencies of cryogen pump, regenerator, engine and refrigerator. Piston based engines with a new valve scheme is experimentally investigated. Compared with small engine, large engine system has apparently larger capacity for power generation, but the engine efficiency is reduced due to the block of the exhaust gas in the chamber. In the presented case study, the efficiency of the large engine is 38.5% while the storage efficiency of the CES system is approximately 22.0%. In the point view of net electricity output for peak-shifting, CES is a feasible technology that need to be further developed. In brief, the work of the CES research are summarized as follows: • Improvement of cold charging/ discharging rate by embedding open-cell metal foams in PCM; • Assessment of cold discharging rate by considering the combined effect of cold radiation and convection; • Optimization of cold storage efficiency by developing computer program based on sub-critical CO2 properties; • Cold to power conversion by using a piston based engine coupled with a new valve scheme.

Thesis (MScAgric)--University of Stellenbosch, 2005.
ENGLISH ABSTRACT: Quality of certain Leucospermum and Leucadendron cultivars after approximately 21 days shipping has been reported to be substandard due to ‘drying out’ of leaves and, in the case of Leucadendrons, involucral leaves. The nature of the symptoms of this ‘drying out’ and the conditions under which they form, viz. long exposures to low temperatures, has led us to hypothesize that these are symptoms of chilling injury (CI). Chilling injury, as far as we are aware, has not been documented on Leucospermums or Leucadendrons. Typical CI symptomology is discussed and shown for Leucospermum ‘Gold Dust’, ‘High Gold’ and ‘Succession’ and for Leucadendron ‘Chameleon’, ‘Laurel Yellow’ and ‘Safari Sunset’. The nature of CI symptoms for Leucospermums and Leucadendrons was generally membranous breakdown that manifested in some cases as a ‘water soaked’ appearance which, at a more advanced stage, was generally visible as ‘dried out’ patches on the leaves. In the case of the Leucadendrons CI was also visible on the immature involucral leaves which are more sensitive to chilling conditions than mature leaves. Dark discoloration of especially immature involucral leaves is also a symptom of CI. As water uptake of shoots with chilling injury is hindered the styles of the Leucospermums wilt. As can be expected, the lower the temperature below the threshold temperature and the longer the exposure the more severe the symptoms. CI was recorded on cut flower shoots of Leucospermum ‘Gold Dust’, ‘High Gold’, ‘Rigoletto’, ‘Succession’ and ‘Vlam’ after 21 and 24 days storage at 1ºC. After 24 days storage the chilling injury was more severe than after 21 days storage in most cases. Each cultivar was pulsed with 5 ml per stem of a 2% (w/v) sugar solution of either lactulose, sucrose, glucose, fructose or mannose before storage. After storage, CI was recorded on day 0, 3, 7 and 10 of the vase phase. Of the cultivars tested ‘Vlam’ and especially ‘Rigoletto’ were more prone to chilling injury development. ‘High Gold’ and ‘Vlam’ shoots were pulsed with 0 (control), 1.5, 3 or 4% (w/v) solutions of either mannose or fructose. The best control of CI for both cultivars was achieved with 1.5% (w/v) solution. Lower concentrations of mannose and fructose were tested on ‘High Gold’ shoots, with a 1% (w/v) solution giving the best control for both. At high concentrations signs of toxicity became evident directly after pulsing. ‘High Gold’ shoots were pulsed with 1% (w/v) solutions of mannose and fructose and sugar analyses were performed on shoots at different stages of storage and after 10 days in the vase. A slight increase in mannose and fructose was detectable in the stems of the shoots directly after pulsing but not in the leaves or the inflorescences. This is due to the low concentrations being used. The levels of all the carbohydrates decreased during the 21 days storage and more so during the vase phase of the flowering shoots. The fact that such low concentrations were effective in controlling chilling injury suggests that the sugars may have an effect other than on the osmotic potential. Cut ‘flower’ shoots of Leucadendron ‘Chameleon’, ‘Laurel Yellow’ and ‘Safari Sunset’ were stored for 14, 21 and 28 days, at 1º, 3º and 5ºC and CI development recorded during the subsequent 10 day vase phase. ‘Laurel Yellow’ and ‘Safari Sunset’ showed signs of chilling injury on the leaves after 28 days storage at 3ºC or lower and ‘Safari Sunset’ stored for 21 days developed chilling injury during the vase phase. Immature involucral leaves were more sensitive to chilling injury than leaves. CI increased with longer exposure times and lower storage temperatures for all three cultivars evaluated. ‘Chameleon’ was the most chilling tolerant of the cultivars up to 21 days. At 5ºC chilling injury was low irrespective of cold storage duration but longer exposures to 1º and 3ºC resulted in increased chilling injury development during the vase phase. All three cultivars were pulsed with 5 ml per stem of a 1% (w/v) solution of lactulose, sucrose, glucose, fructose or mannose and stored for 14, 21 and 28 days at 1ºC. The sugars reduced chilling injury on the leaves for ‘Safari Sunset’ when stored for 28 days and, to a lesser extent, in ‘Chameleon’. The sugars failed to reduce chilling injury of the involucral leaves of ‘Chameleon’ and ‘Laurel Yellow’ whereas there was some control especially after 28 days for ‘Safari Sunset’. In some cases the sugar pulse exacerbated chilling injury. Chilling injury generally increased rapidly after storage during the first three days in the vase and then at a lower rate for the next seven days. Leucadendron ‘Chameleon’, ‘Laurel Yellow’ and ‘Safari Sunset’ ‘cut flower’ shoots were pulsed with a 1% (w/v) glucose solution. Expressed on a dry weight basis, an increase in glucose concentration was not detected. The reduction in chilling injury of leaves by a sugar pulse is speculated, as for the Leucospermums, to be as a result of their presence in the apoplast and not the symplast and that their presence there protects the membranes against chilling conditions in some way.
AFRIKAANSE OPSOMMING: Die kwaliteit van sekere Leucospermum en Leucadendron kultivars na ongeveer 21 dae verskeping is waargeneem as substandaard as gevolg van die uitdroog van blare en, in die geval van Leucadendrons, die ‘involucral’ blare. Die aard van die simptome van hierdie uitdroging en die toestande waaronder dit plaasvind nl. lang periodes van blootstelling aan lae temperature, het ons tot die hipotese gebring dat hierdie simptome van koueskade is. Sover as wat ons bewus is, is koueskade nog nie gedokumenteer op Leucospermums of Leucadendrons nie. Tipiese koueskade simptomologie word bespreek en gewys vir Leucospermum ‘Gold Dust’, ‘High Gold’ en ‘Succession’ en vir Leucadendron ‘Chameleon’, ‘Laurel Yellow’ en ‘Safari Sunset’. Die koueskade simptome vir Leucospermums en Leucadendrons was oor die algemeen membraan afbraak wat ‘n water deurdrenkte voorkoms tot gevolg gehad het wat in ‘n meer gevorderde stadium sigbaar was as uitgedroogde kolle op die blare. In die geval van Leucadendrons was koueskade ook sigbaar op die onvolwasse ‘involucral’ blare wat meer sensitief is vir koue toestande as volwasse blare. Donker verkleuring van veral onvolwasse ‘involucral’ blare is ook ‘n simptoom van koueskade. Aangesien wateropname van stele met koueskade verhinder word, verwelk die ‘styles’ van die Leucospermums. Soos verwag kan word hoe laer die temperature onder die drempel temperatuur en hoe langer die blootstelling, hoe meer ernstig die simptome. Koueskade is aangeteken op gesnyde blomstele van Leucospermum ‘Gold Dust’, ‘High Gold’, ‘Rigoletto’, ‘Succession’ en ‘Vlam’ na 21 en 24 dae opberging by 1°C. Na 24 dae opberging was die koueskade meer ernstig as na 21 dae opberging in meeste gevalle. Elke kultivar het 5ml per steel van ‘n 2% (g/v) suiker oplossing van laktolose, sucrose, glucose, fruktose of mannose voor opberging opgeneem. Na opberging is koueskade aangeteken op dag 0, 3, 7 en 10. Van die kultivars wat getoets is, was ‘Vlam’ en veral ‘Rigoletto’ meer geneig tot koueskade ontwikkeling. ‘High Gold’ en ‘Vlam’ stele is geplaas in oplossings van 0 (kontrole), 1.5, 3 of 4 % (g/v) oplossings van mannose of fruktose. Die beste beheer van koueskade vir beide kultivars is deur die 1.5 (g/v) oplossing behaal. Laer konsentrasies van mannose en fruktose is getoets op ‘High Gold’ stele met ‘n 1% (g/v) mannose oplossing wat die beste beheer gegee het. Met hoë konsentrasies het tekens van toksisiteit sigbaar geword direk na opneem van die oplossing. ‘High Gold’ stele is geplaas in 1% (g/v) oplossings van mannose of fruktose en suiker analises is uitgevoer op stele by verskillende stadiums van opberging en na 10 dae in die vaas. ‘n Effense toename in mannose en fruktose is waargeneem in die stele van die blomme direk na opname van die oplossing, maar nie in die blare of die blomme nie. Dit is as gevolg van die lae konsentrasies wat gebruik is. Die vlakke van al die koolhidrate het afgeneem gedurende die 21 dae opberging en nog meer so gedurende die vaas periode van die blommende stele. Die feit dat sulke lae konsentrasies effektief is in die beheer van koueskade dui daarop dat die suikers ‘n effek het anders as op die osmotiese potensiaal. Snyblomme van Leucadendron ‘Chameleon’, ‘Laurel Yellow’ en ‘Safari Sunset’ is opgeberg vir 14, 21 en 28 dae, by 1º, 3º en 5°C en koueskade ontwikkeling is aangeteken gedurende die opvolgende 10 dae vaas periode. ‘Laurel Yellow’ en ‘Safari Sunset’ het tekens gewys van koueskade op die blare na 28 dae opberging by 3°C of laer en ‘Safari Sunset’ opgeberg vir 21 dae het koueskade ontwikkel gedurende die vaas periode. Onvolwasse ‘involucral’ blare was meer sensitief vir koueskade as die blare. Koueskade het toegeneem met langer blootstellingstye en laer opbergins temperature vir al drie kultivars geëvalueer. ‘Chameleon’ was die mees koueverdraagsaam van die drie kultivars tot op 21 dae. By 5°C was laag ongeag van die koue opberging tydperk, maar langer blootstellings aan 1º en 3°C het gelei tot toename in koueskade ontwikkeling gedurende die vaas periode. Al drie kultivars is voorsien met 5ml per steel van ‘n 1% (g/v) oplossing van lactulose, sucrose, glucose, fruktose of mannose en opgeberg vir 14, 21 en 28 dae by 1°C. Die suikers het koueskade verminder op die blare van ‘Safari Sunset’ wanneer opgeberg vir 28 dae en, tot ‘n mindere mate, in ‘Chameleon’. Die suikers het egter nie koueskade verminder van die ‘involucral’ blare van ‘Chameleon’ en ‘Laurel Yellow’ nie, waar daar egter wel in ‘n mate beheer was veral na 28 dae vir ‘Safari Sunset’. In sommige gevalle het die voorsiening van suiker die koueskade vererger. Koueskade het oor die algemeen vinnig toegeneem na opberging gedurende die eerste drie dae in die vaas en dan teen ‘n laer tempo vir die volgende sewe dae. Leucadendron ‘Chameleon’, ‘Laurel Yellow’ en ‘Safari Sunset’ snyblom stele is voorsien van ‘n 1% (g/v) glukose oplossing. Uitgedruk op ‘n droëmassa basis is ‘n toename in glukose konsentrasie nie waargeneem nie. Die afname in koueskade van blare deur die voorsiening van ‘n suiker oplossing is gespekuleer vir die Leucospermums, om ‘n resultaat te wees van hulle teenwoordigheid in die apoplas en nie die simplas nie, en dat die teenwoordigheid daar die membrane op ‘n manier beskerm teen koue toestande.

This master thesis contributes to the design of a stratified cold-water storage. The objective is to provide a second opinion on the design of the water distributors and charging/ discharging parameters, by means of numerical simulations. The first chapter is an introduction to district cooling, it provides some concepts essentials to the understanding of this project and details the challenges associated with the particular case of a stratified cold-water storage. The second chapter focuses on fluid dynamics considerations. The third chapter reminds the fundamentals of perforated distributors theory, derives formula for pressure evolutions in the distributor and a design criterion. The fourth and fifth chapters give the results of the numerical simulations. For the distributor’s design, the theory has been tested by numerical methods which gave coherent results. A design has been determined. Regarding thermocline formation, we observed that injection water at 14C led to a thermocline of 2.5 m. All other things remaining equal, using the district heating network to inject water at 25C leads to a thermocline of 1 m. When it comes to thermocline evolution, the results brought out the limited influence of either the number of pipes or the flow rates characteristics on the thickness evolution.
Den här masteruppsatsen bidrar till designen av ett stratifierat kyllager. Syftet är att, med hjälp av numeriska simulationer, tillhandahålla en annan åsikt om designen av vattenfördelningen och laddning/urladdningsparametrar. Det första kapitlet är en introduktion till fjärrkyla, där några koncept som är essentiella för förståelsen av det här projektet redovisas och på ett detaljerat tillvägagöngssätt studerar utmaningarna associerade med det särskilda fallet av ett stratifierat kyllager. Det andra kapitlet fokuserar på fluiddynamiska teorier. Det tredje kapitlet erinrar om grundprinciperna av perforerad rörteori som erhåller formler för tryckevolution i fördelaren samt ett designkriterium. Det fjärde kapitlet visar resultaten av de numeriska simulationerna. För designen på fördelaren har teorin blivit testad av numeriska metoder som givit sammanhängande resultat. En design har blivit fastställd. Angående termoklinbildningen observerades att vatten som injicerats vid 14C ledde till en termoklin på 2.5 m. Utan att ändra de andra parametrarna blir resultatet en termoklin på 1 m när vatten injicerats vid 25C med hjälp av ett fjärrvärmenät. När det gäller termoklinevolutionen har resultaten konstaterat den limiterade influensen av antalet rör eller flödeshastighetens karaktär på tjockleksevolutionen.

An evaluation of the use of short-term cold storage of tomatoes to tide over the cyclical market glut of horticultural products was conducted in Coimbatore, Tamil Nadu, India. Farmers stored their harvest at a rental commercial cold-storage facility in the city and at an experimental cold store at the Tamil Nadu Agricultural University in Coimbatore. The goal was to study the storage characteristics of the produce as well as to assess the economic benefits of adopting such an intervention. The temperature and relative humidity conditions at both locations and the fate of the produce were monitored. The proportion of marketable produce diminished significantly as the storage period increased, with major losses occurring due to microbial damage. Differences in the air conditions at the locations did not have a significant effect on the storage-related losses of produce. Economic analysis showed that short-term cold storage would not aid farmers unless measures were taken to reduce the microbiological losses during postharvest handling.
Une évaluation d'entreposage de tomates à court terme a été effectuée à Coimbatore, dans l'état du Tamil Nadu en Inde, dans le but d'aider les fermiers à pallier la saturation cyclique du marché des fruits et légumes frais. Des fermiers ont entreposé leur récolte de tomates dans un entrepôt frigorifique commercial situé dans la ville, ainsi que dans un entrepôt frigorifique expérimental situé dans le Tamil Nadu Agricultural University dans la même ville indienne. Le but de l'expérience était d'étudier les caractéristiques d'entreposage du produit, ainsi que d'évaluer les bénéfices économiques liés à l'adoption d'une telle intervention. La température, l'humidité relative et le sort des produits horticoles ont été surveillés. Avec l'augmentation des temps d'entreposage, la proportion des fruits frais ayant une valeur marchande a baissé considérablement; la plupart des pertes était due à des infections microbiennes. Les différences dans les conditions ambiantes des deux entrepôts n'ont pas eu d'effet considérable sur les pertes de fruits frais dues à l'entreposage. Une analyse économique a démontré que l'entreposage à court terme n'aidera pas les fermiers à moins que des mesures supplémentaires soient adoptées afin de réduire les pertes microbiennes durant les manipulations post-récoltes.

Electrical energy storage (EES) has emerged as a key enabler for access to electricity in remote environments and in those environments where other external factors challenge access to reliable electricity. In cold climates, energy storage technologies face challenging conditions that can inhibit their performance and utility to provide electricity. Use of available energy storage technologies has the potential to improve Army installation resilience by providing more consistent and reliable power to critical infrastructure and, potentially, to broader infrastructure and operations. Sustainable power, whether for long durations under normal operating conditions or for enhancing operational resilience, improves an installation’s ability to maintain continuity of operations for both on- and off-installation missions. Therefore, this work assesses the maturity of energy storage technologies to provide energy stability for Army installations in cold regions, especially to meet critical power demands. The information summarized in this technical report provides a reference for considering various energy storage technologies to support specific applications at Army installations, especially those installations in cold regions.

Reliable vehicle start is necessary to support mission success, especially for response time. At Department of Defense installations in cold regions, vehicles using rechargeable battery and starter technologies have significant issues starting in the cold. Ultracapacitor engine start modules (ESMs) are an alternate technology to rechargeable lead-acid or lithium-ion batteries. The project develops a performance baseline for the ESM used in the M1126 Stryker Combat Vehicle under cold conditions. To test the performance of the ESMs in a cold room, a mechanical load system was constructed to replicate the load of starting a Stryker engine and instrumented with sensors to monitor parameters such as voltage, torque, and temperature. The ESMs were tested with the load system at temperatures from 24°C to −40°C. The results of the tests showed that there was some degradation of the ultracapacitor’s performance at the colder temperatures, which was expected, but no permanent damage. This work provides a test protocol and capability to evaluate next-generation vehicle battery systems for cold regions applications. Additionally, the ESM cold performance data establish a baseline to compare next-generation vehicle battery storage systems and to support cold regions missions and identify potential performance requirements for future vehicle battery system acquisition.
