Texto completoI denna avhandling formuleras två optimala styrningsproblem för reglering av hybridelektriska fordon. I den första, mer generella, formuleringen kan både hastighet och batteriladdning variera. I den andra formuleringen är hastigheten specifierad i förväg and därmed kan endast batteriladdningen variera fritt. Den första formuleringen tar betydligt längre tid att lösa med dynamisk programmering än den andra formuleringen. Av dem utvärderade körcyklerna gav den som var mest kuperade bränslebesparingar på 4:45 % om den löstes med den generella formuleringen istället för den där hastigheten är specifierad i förväg. När den lägsta tillåtna hastigheten sänktes från 75 till 70 km/h sparades 0:52 % bränsle. Däremot, om den lägsta tillåtna hastigheten sänktes från 80 till 70 km/h ökade besparingen till 1:92 %. Sammanfattningsvis, om dynamisk programmering ska implementras i realtid på ett hybridelektriskt fordon så är dem potentiella bränslebesparingarna betydligt högre om vägen är väldigt kuperad och en låg lägsta hastighet tillåts för den generella formuleringen än om formuleringen med hastighet specifierad på förhand väljs. Därmed, för vägar som inte är lika kuperade och där hastigheten inte tillåts att variera mycket kan, potentiellt, högre bränslebesparingar uppnås om formuleringen med förspecifierad hastighet väljs och förmågan att växla alternativt stänga av eller på motorn inkluderas.

Texto completoPlug-in Hybrid Electric Vehicles (PHEV) are new generation Hybrid Electric Vehicles (HEV) with larger battery capacity compared to Hybrid Electric Vehicles. They can store electrical energy from a domestic power supply and can drive the vehicle alone in Electric Vehicle (EV) mode. According to the U.S. Department of Transportation 80 % of the American driving public on average drives under 50 miles per day. A PHEV vehicle that can drive up to 50 miles by making maximum use of cheaper electrical energy from a domestic supply can significantly reduce the conventional fuel consumption. This may also help in improving the environment as PHEVs emit less harmful gases. However, the Energy Management System (EMS) of PHEVs would have to be very different from existing EMSs of HEVs. In this thesis, three different Energy Management Systems have been designed specifically for PHEVs using simulated study. For most of the EMS development mathematical vehicle models for powersplit drivetrain configuration are built and later on the results are tested on advanced vehicle modeling tools like ADVISOR or PSAT. The main objective of the study is to design EMSs to reduce fuel consumption by the vehicle. These EMSs are compared with existing EMSs which show overall improvement. x In this thesis the final EMS is designed in three intermediate steps. First, a simple rule based EMS was designed to improve the fuel economy for parametric study. Second, an optimized EMS was designed with the main objective to improve fuel economy of the vehicle. Here Particle Swarm Optimization (PSO) technique is used to obtain the optimum parameter values. This EMS has provided optimum parameters which result in optimum blended mode operation of the vehicle. Finally, to obtain optimum charge depletion and charge sustaining mode operation of the vehicle an advanced PSO EMS is designed which provides optimal results for the vehicle to operate in charge depletion and charge sustaining modes. Furthermore, to implement the developed advanced PSO EMS in real-time a possible real time implementation technique is designed using neural networks. This neural network implementation provides sub-optimal results as compared to advanced PSO EMS results but it can be implemented in real time in a vehicle. These EMSs can be used to obtain optimal results for the vehicle driving conditions such that fuel economy is improved. Moreover, the optimal designed EMS can also be implemented in real-time using the neural network procedure described.

Texto completoThe focus of this PhD thesis is to design an optimal Energy Management System (EMS) for a Hybrid Electric Vehicle (HEV) following traffic constraints.In the current state of the art, EMS are typically divided between real-time designs relying on local optimization methods, and global optimization that is only suitable for off-line use due to computational constraints.The starting point of the thesis is that in terms of energy consumption, the stochastic aspect of the traffic conditions can be accurately modelled thanks to (speed,acceleration) probability distributions.In order to reduce the data size of the model, we use clustering techniques based on the Wasserstein distance, the corresponding barycenters being computed by either a Sinkhorn or Stochastic Alternate Gradient method.Thanks to this stochastic traffic model, an off-line optimization can be performed to determine the optimal control (electric motor torque) that minimizes the fuel consumption of the HEV over a certain road segment.Then, a bi-level algorithm takes advantage of this information to optimize the consumption over a whole travel, the upper level optimization being deterministic and therefore fast enough for real-time implementation.We illustrate the relevance of the traffic model and the bi-level optimization, using both traffic data generated by a simulator, as well as some actual traffic data recorded near Lyon (France).Finally, we investigate the extension of the bi-level algorithm to the eco-routing problem, using an augmented graph to track the state of charge information over the road network

Texto completoLastbils -och busstillverkaren Scania CV AB har nyligen introducerat ett system vid namnet Redundant Brake Steering (RBS) för elektrifierade fordon. Det primära styrsystemet i dessa fordon består av ett elektro-hydraliskt system (EHS) samt ett elektriskt aktivt styrsystem (EAS). Bakgrunden till att introducera RBS har varit grundat i att kunna implementera EAS som sekundärt styrsystem för att tillfredställa nuvarande lagkrav. Utfallet har blivit att det sekundära hydrauliska styrsystemet har kunnat ersättas med bromsstyrningssystem (RBS) samt EAS. Den grundläggande ambitionen för denna studie har varit at utforska ifall det nya bromsstyrningssystemet kan bidra till minskad energiförbrukning av fordonets styrsystem. Denna studie har bland annat innefattat en litteraturstudie av styrsystem, koncept som berör bromsstyrning samt tillgänglig fordonsdata för att kunna utveckla beräkningsmetoder av energiförbrukning av respektive system. Metoderna användes för att utveckla en beräkningsmodell i mjukvaran Matlab som med hjälp av fordonsdata kunde uppskatta energiförbrukningen av styrsystemen. Fordonstester utfördes i en fallstudie för att kunna samla in mätningar av fordonsdata. Detta gjordes med hjälp av ett plug-in hybrid fordon (PHEV) på Scania’s provbana i Södertälje, Sverige. Resultaten indikerade att en kombination av EAS och RBS har potential att bistå som primärt styrsystem sett till energiförbrukningen vilken kunde reduceras med upp till 90.6%. Vidare visade resultaten att påfrestningen på fordonets elektriska system kunde minskas, dock med nackdelen att förarens ansträngning ökar.

Texto completoThe research work presented in this document is a continuation of the GREAH laboratory research activities on the issues of optimal energy management on board of electric and hybrid electric vehicles. Indeed, the coupling of several electrical energy sources with different characteristics causes several issues like energy sources sizing, energy exchange quality and the lifetime of the interconnected elements. In the case of transport applications, the main factors of these problems are based on the high fluctuations in the power required by the propulsion/traction chain; the limited life expectancy of the electrical energy storage elements; the lack of realistic standard mission profile and the need to optimize the electric vehicles energy consumption. The appropriate method for studying the multi-source systems is by using systemic approach. This approach is necessary to establish behavioral models of energies sources and power converters for the development of optimal energy management strategies. The contribution of this thesis is focused on the investigation and the development of energy management strategies considering the electrical energy sources performances and their state of functioning according to the power fluctuations from the propulsion/traction chain, which presents the load in a touristic vehicle

Texto completoThe rapid development of electric vehicles (EVs) increases the power demand, which causes an extra burden on the public grid increasing the load fluctuations, therefore, hindering the high penetration of EVs. A real-time rule-based algorithm for electric vehicle (EV) charging stations empowered by a DC microgrid is proposed to deal with the uncertainties of EV users’ behaviour considering its arbitrary and random choices through the human-machine interface, meanwhile considering most of the users’ choices. The simulation results obtained under MATLAB/Simulink verify the feasibility of the proposed management strategy that presents a good performance in terms of precise control. In addition, EV shedding and restoration optimization algorithms (SROA) for battery charging power can be used to meet user needs while maintaining EV charging station power balance, taking into consideration the intermittency of the photovoltaic (PV) source, the capacity limitation of the storage, and the power limitation of the public grid. The simulation results show that compared with rule-based algorithm, the proposed SROA respect the user's choice while reducing total charging time, increasing the full rate, and maximizing the available power utilization, which shows the feasibility and effectiveness of SROA. Furthermore, a PV based charging station for EVs can participate to solve some peak power problems. On the other hand, vehicle to grid (V2G) technology is designed and applied to provide ancillary services grid during the peak periods, considering the duality of EV battery “load-source”. So, a dynamic searching peak and valley algorithm, based on energy management, is proposed for an EV charging station to mitigate the impact on the public grid, while reducing the energy cost of the public grid. Simulation results demonstrate the proposed searching peak and valley algorithm effectiveness, which can guarantee the balance of the public grid, meanwhile satisfy the charging demand of EV users, and most importantly, reduce the public grid energy cost

Texto completoFor a hybrid electric vehicle, one of the most challenging aspects from a control perspective is the power split between the engine and the motors, problem referred to as energy management. The question that arises is how to exploit the additional degree of freedom - the electric path - such that the vehicle performance related to consumption is improved. The required robustness for the control strategies encourage the choice of model-based methods and in the present context of telemetry data acquisition, model predictive control emerges as an attractive option, motivated in addition by its ability to handle the constraints. Most of the current energy management strategies are application-oriented and therefore, a generic hybrid powertrain model would provide more flexibility. This thesis is developed on two main axes: the synthesis of a generic model and of a MPC-based control strategy for the energy management, with a self-tuning mechanism. If the torque split is the main control objective, other functionalities can be introduced, such as engine stop/start and coasting. The latter is usually handled in the literature with a map-based strategy, but here an analytical solution was proposed. A validation on a vehicle high-fidelity model for a mild hybrid with a dual-clutch transmission closes the work and shows the potential of the proposed strategy

Texto completoThis thesis presents the research of energy management in a battery/ultracapacitor hybrid energy storage system with exogenous disturbance in hybrid electric vehicular application. Transient and harmonic persistent disturbances are the two kinds of disturbances considered in this thesis. The former is due to the transient load power demand during acceleration and deceleration, and the latter is introduced from the process of the internal combustion engine torque ripples compensation. Our control objective is to absorb the disturbances causing battery wear via the ultracapacitor, and meanwhile, to maintain a constant DC voltage and to compensate the self-discharge in the ultracapacitor to maintain it operating at the nominal state of charge. The object system is nonlinear due to the multiplicative relation between the input and the state. The traditional approach to solve Francis-Byrnes-Isidori equations cannot be directly applied in this case since the interconnect matrix depends on the control input. Besides, even if this approach is well suited to the rejection of persistent disturbances, it shows the limits for the case of non-persistent disturbances which is also our object. Our contributed control method is realized through a cascade control structure based on the singular perturbation theory. The ultracapacitor current with the fastest motion rate is controlled in the inner fast loop through which we impose the desired dynamic to the system. The reduced system controlled in the outer slow loop is a Hamiltonian system and the controller is designed via interconnection and damping assignment. Simulations and experiments have been carried out to evaluate the control performance. A contrast of the system responses with and without the control algorithm shows that, with the control algorithm, the ultracapacitor effectively absorbs the disturbances; and verifies the effectiveness of the control algorithm

[EN] Energy plays a significant role for the sustainable development of communities. Hence, supplying reliable energy resources, which result economically acceptable, environmentally friendly and socially beneficial, arises as essential for their sustainable development. Despite the universality of such definition, the energy use is highly linked to the development degree of the countries. Thus, energy problems of developed countries sharply contrast with those of developing countries. This doctoral thesis identifies the main energy issues of both realities: severe environmental impact of energy generation models for traditional transport in developed countries and energy poverty in developing countries. The compendium of scientific papers of this doctoral dissertation characterizes the use of advanced renewable energy systems to solve such problems in a sustainable way. Namely, the main energy issue in developed countries has been addressed by means of energy planning and the optimal design of Hybrid Renewable Energy Systems (HRES) in electric vehicle charging stations, which ensure the introduction of electric vehicles as a sustainable mobility alternative. Moreover, the study of methodologies for the optimal design of off grid HRES and improved cooking stoves based on biomass gasification have approached the inaccessibility to electricity and to clean cooking systems that developing communities suffer. Therefore, this thesis provides a number of methodologies to optimize and adapt the presented renewable energy systems for the sustainable energy development of communities. Furthermore, it demonstrates not only the suitability of these systems for such aim, but also their versatility of application regarding the growing degree of the communities.

Este trabalho tem como contribuição o desenvolvimento de uma estratégia de equa-lização das tensões em um conversor multinível modular, como parte integrante de um sistema híbrido de armazenamento de energia. O conversor modular multinível realiza a conexão em série de módulos supercapacitores, o que possibilita aumentar a ten-são sem prejudicar a transferência rápida de energia. Em relação à outras topologias, este trabalho permite reduzir a quantidade, volume e massa do elemento magnético da estrutura do conversor. Um banco de baterias de íons de lítio também integra o sistema por intermédio de um conversor estático. Como é a fonte de maior densidade de energia, fornece a potência média requerida pelo carga. A associação com uma fonte de transferência rápida de energia permite aumentar o desempenho dinâmico, a eficiência energética e a vida útil da bateria. Com efeito, tem-se um sistema híbrido de armazenamento de energia que requer estratégias de gestão para múltiplas fontes de suprimento. Os resultados simulados considerando a estimativa da demanda de po-tência de um protótipo de veículo elétrico, são adequados e propiciam os fundamentos necessários para a construção de um protótipo.
This work is a contribution to develop a strategy equalization of tensions in a mo-dular multilevel converter as part of a hybrid system energy storage. The multilevel modular converter realizes the series connection of supercapacitor modules, which al-lows to increase the voltage without cause damages to the quick energy transfer. In relation to other topologies, it allows reduction of the quantity, volume and mass of the magnetic element of the converter structure. A lithium-ion battery bank also integrates the system via a voltage boost converter. This battery is the source of high energy density, which provides the average power required by the load. The association with a fast transfer power source allows for increased dynamic performance, energy efficiency and service life. In fact, there is a hybrid energy storage system that requires mana-gement strategies for multiple sources of supply. The simulated results were obtained considering the power demand estimation of an electric vehicle prototype.

Texto completoThis thesis contributes to the improvement of hybrid embedded source performances supplies an electric vehicle. The studied solution is composed of Li-ion batteries and supercapacitors hybridization, with an aim to achieve improved performances in terms of weight and lifetime over traditional solutions. Our main goal is to take the best advantage of new energy management strategies of the hybrid embedded source and quantify obtained improvements. A multi-physic model including electric, thermal and aging behaviors is developed and integrated into the algorithm of energy management in order to evaluate the gradual degradation of storage components performances during driving cycles and implemented control strategy. New energy management strategies intended to act on the lifetime of hybrid embedded source have been evaluated. Their impact on the performances of the source in terms of weight, cost and lifetime has been quantified and clearly shows that it is possible to make better use of hybrid embedded source thanks to a good power sharing, thus opening the way to new approaches of energy management for these systems

Texto completoThis thesis proposes an Adaptive Rule-Based Energy Management Strategy (ARBS EMS) for a parallel hybrid electric vehicle (P-HEV). The strategy can effciently be deployed online without the need for complete knowledge of the entire duty cycle in order to optimize fuel consumption. ARBS improves upon the established Preliminary Rule-Based Strategy (PRBS) which has been adopted in commercial vehicles. When compared to PRBS, the aim of ARBS is to maintain the battery State of Charge (SOC) which ensures the availability of the battery over extended distances. The proposed strategy prevents the engine from operating in highly ineffcient regions and reduces the total equivalent fuel consumption of the vehicle. Using an HEV model developed in Simulink, both the proposed ARBS and the established PRBS strategies are compared across eight short duty cycles and one long duty cycle with urban and highway characteristics. Compared to PRBS, the results show that, on average, a 1.19% improvement in the miles per gallon equivalent (MPGe) is obtained with ARBS when the battery initial SOC is 63% for short duty cycles. However, as opposed to PRBS, ARBS has the advantage of not requiring any prior knowledge of the engine effciency maps in order to achieve optimal performance. This characteristics can help in the systematic aftermarket hybridization of heavy duty vehicles.

In this research, the SOC of the battery system is applied to amend the power that the generator need to produce, helping keep the SOC of the battery system close to the ideal value and reduce the SOC swing; the difference between the needed power and the real power of the generator is used to dynamically limit the generated power change rate, keeping the power efficiency high at normal driving situation and avoiding the battery current from overloading when accelerating and decelerating rapidly. By using this method, the oil efficiency and the battery life can be improved. This research uses ADVISOR to simulate the performance of the SHEV system at NEDC cycle, compares with other control strategies, and simulates and analyzes the performance under rapid accelerating and decelerating, constant speed climbing, and driving on mountain road at high speed. Finally, this research discusses and simulates the influence of system aging on the performance of the control strategy.
