In the Electric Vehicle(EV) driving system, the Battery Management System(BMS) is very important and an essential equipment.<br/> Particularly, BMS monitors the State of Charge(SOC), voltage, current, and temperature of the battery modules when Electric Vehicle is in the state of motoring or charging. Major roles of BMS are like these the first, estimation of State of Charge(SOC), the second, detection of the unbalance of the voltage between battery modules, the third, control of the available limit of the voltage and temperature of batteries by monitoring the batteries' status during motoring or charging. In this research, We have focused on estimating SOC of battery according to the status of Electric Vehicle and the BMS operation algorithm. The result for algorithm of SOC estimation is presented. It have been modified, compensated, and verified by means of the experiment.

Many countries are concentrating on the development of electric vehicle technology with increasing concerns about the global environment. Along with these concerns, plug-in hybrid electric vehicles(PHEVs) are being developed as environment-friendly cars which reduce greenhouse gas emissions and also eliminate the problem of range anxiety associated to all-electric vehicles, because the combustion engine works as a backup when the batteries are depleted. In this paper, electric equipments of the PHEV which meet the target specifications were developed, and their performance was proven through confirmatory testing on the PHEV at Korea Automotive Technology Institute(KATECH).

전기자동차의 추진시스템의 경우 차량의 종류에 따라 제어기 변수의 변동이 많은 것이 특정이다. 따라서 다양한 차량의 종류에 대해 소스프로그램의 수정 없이 차량 시스템 튜닝작업이 용이하도록 제어프로그램을 구현하는 것이 중요하며 이런 목적에 맞는 제어파라미터의 선정이 중요하게 된다. 또한 전기자동차는 승객의 안전과 직결되기 때문에 시스템 fault 처리에 대한 중요성이 높다. 본 논문에서 는 전기 자동차 추진시스템의 제어기의 소프트웨어 구현에 대해 논한다.

Generally, brushless DC motor(BLDCM) driving system uses hall sensors or encoders as the mechanical position or speed sensors It is necessary to achieve the informations of rotor position for driving trapezoidal type brushless DC motor without any position sensor.<br/> This paper proposes a sensorless driving system with rotor absolute position detector circuit which acquires both commutate phase and commutate time by analyzing motor phase voltages Proposed system is applied to a 10k[W] rating motor which actually used in electrical vehicles of HONDA co,ltd The experimental results will show the validity of the proposed system and the practical use of proposed sensorless drive algorithm
