Повний текст джерелаIn order to cope with environmental problems and climate change, electric vehicles (EVs) gain the ever booming development in recent years. From the point of view of energy storage, because of their high energy / power density and their extended lifespan, it is essentially the lithium-ion battery (LIB) technology which is the most used power unit for EVs. Doubtlessly, the reliability of LIBs is of vital importance for the development of EVs. To this end, this thesis is dedicated to the algorithmic development of battery state and parameter estimation as well as incipient short-circuit diagnosis. The battery state and parameter estimation, which can also be termed as battery monitoring, is a critical part in the so-called health conscious energy management strategy for electric or hybrid electric vehicle. Premature aging can be avoided through the accurate battery state estimation such as state of charge (SOC) and state of health (SOH). Furthermore, as the thermal runaway (TR) can be ultimately attributed to short-circuit (SC) electrical abuse, therefore, effective battery incipient SC detection can give an early warning of TR. The main contribution of this thesis lies in the theoretical and methodological aspects in the domain of battery monitoring and incipient SC diagnosis

Повний текст джерелаRadiotomografisk avbildning (RTA) är en ny, anordningsfri lokaliseringstekniksom utnyttjar förändringarna i radiosignaler orsakat av obstruktioner för att möjliggöraolika avkänningsapplikationer. Utvecklingen av dessa applikationer hindrasemellertid av de energiineffektiva radioavkännande tekniker som användsi dessa system. I denna avhandling behandlar vi problemet genom att introduceraen ny metod för att skapa en batterifri RTA-sensor. Vi går igenom konstruktionsprocessenoch producerar och utvärderar en arbetsprototyp som kräver minusklermängder energi. Vår design minskar energiförbrukningen signifikantjämfört med traditionella RTA-sensorer, genom att eliminera de energiineffektivakomponenterna som används i dagens RTA-system, vilket möjliggör batterifridrift av RTA-sensorer. Vi demonstrerar effektiviteten och noggrannheten hos vårtsystem i ett gränsöverskridande scenario. Vi diskuterar begränsningarna och taritu med några av de säkerhetshot som är korrelerade med utplaceringen av ettsådant system.

These batterieshave a bad impact on the environment as much energy and environmentallyhazardous materials like lead and sulfuric acid are required to manufacture thesebatteries. Östersjökompaniet AB and many of its customers realize the importanceof sustainable thinking and were interested in knowing if it was possible tomaximize the lifetime of these batteries. During the course of the work, differentmethods of battery charging and discharging were analyzed that could affect thebatteries lifetime and how to take care of them to optimize them. A chargecontroller was used to optimize the charge of the battery. To calculate theremaining state of charge in the battery, the Extended voltmeter method was used.A prototype that was able to charge the batteries optimally, warn when the batterycapacity became too low, and a user-friendly application for battery monitoring wasdesigned. The calculated lifetime of a battery is not an exact science. According tostudies the lifetime of a battery can be doubled if it is c

Many of portable devices, such as mobile phone and notebook, have grown explosively in recent years. The electric power demand of these devices almost relies on small energy storage element. Therefore, the rechargeable batteries have been widely used to power these equipments. Under the concepts, this thesis is aimed to develop a real-time battery information platform with the intelligent energy estimation based on the monitoring and computation of programmable ARM-based system, Labview, and dsPIC micro-controller. In this method, the polynomial function is firstly included through the measurement of output voltage with respect to a certain SOC value. Then using the obtained function of battery intrinsic, a method to estimate residual energy of battery is suggested. The method proposed in this thesis is examined under various scenarios. The results help consolidate the feasibility and practicability of the approach for the applications considered.

Temperature distribution, electrolyte flow rate, voltage, and current play very critical roles in terms of the performance and service life of a vanadium redox flow battery (VRFB). The fuel delivery of a vanadium redox flow battery uses a pump to deliver electrolyte from the outside to the inside for reaction. Since only external machines can be used to adjust the pump speed so as to control the flow rate of electrolyte, best performance cannot be achieved yet. In terms of the demand of real-time microscopic diagnosis of vanadium redox flow battery, as this work, the researcher hereby proposes that the researcher will use micro-electro-mechanical systems (MEMS) to develop a flexible integrated (temperature, flow, voltage, and current) micro-sensor and embed it inside a vanadium redox flow battery to conduct real-time microscopic sensing and diagnosis. The advantages of this innovative technology include (1) It has small volume; (2) The position of measurement is elastic. And the micro-sensor can be embedded accurately; (3) It is highly accurate and sensitive with short response time; (4) It can be customized in terms of design and development. The flexible integrated micro-sensor can accurately measure the real-time operating conditions inside the vanadium redox flow battery and can feedback internal information in a real-time manner so that the control system of the stack can be adjusted to optimum operating parameters and effectively increase its performance and service life.

Повний текст джерелаThe current global challenge of climate change has made renewable energy usage very important. There is an ongoing drive for the deployment of renewable energy resource at the domestic level through feed-in tariff, etc. However the intermittent nature of renewable energy has made storage a key priority. In this work, a community having a solar farm with energy storage embedded in the house of the energy consumers is considered. Consumers within the community are aggregated in to a local virtual power plant. Genetic algorithm was used to develop an optimized energy transaction for the virtual power plant. The results shows that it is feasible to have a virtual power plant setup in a local community that involve the use of renewable generation and embedded storage. The result also show that when maximization of battery state of charge is considered as part of an optimization problem in a day ahead market, certain trade-off would have to be made on the profit of the virtual power plant, the incentive of the prosumer, as well as the provision of peak service to the grid.

Bootstrap detector and soft-start embedded in Type Ⅲ compensation are implemented in the switch-mode lithium-ion charger to achieve robustness and high efficiency. Based on the physical properties of the battery cell, the charger charges the cell with three stages, which are trickle current (TC), constant current (CC), and constant voltage (CV) stages [1], [2]. How to deliver power to charge battery in an optimal and safe way is important for fast charging. Switch-mode charger is able to guarantee high efficiency regardless of the applications and provides higher current capability to accelerate charging process. To ensure the stability of both CC stage and CV stage, the switch-mode charger employ one Type Ⅲ compensation circuit to two parallel loop CC loop and CV loop. For applications with removable battery packs, a soft-start mechanism is necessary to ensure the operation of charger system and prevent inrush current whether battery is connected or not. Considering area and cost, two N-type power MOSFETs is adopted in the switch-mode charger. For appropriate turn-on resistance to maintain high efficiency and prevent the power MOSFET to burn out, the gate-source voltage of the N-type power MOSFET should be large enough. The proposed BSD monitors the voltage across the bootstrap capacitor, which is the source applies the high side power MOSFET driving voltage to avoid low efficiency and serous burning problem in both synchronous and non-synchronous charging mode. Furthermore, soft-start embedded in type Ⅲ compensation technique employs the compensation elements and the error amplifier of the type Ⅲ compensation circuit to achieve soft-start function without any external components and auxiliary circuits to greatly minimize the chip and footprint areas.
