Automatic monitoring system of battery stack for electric vehicles

Electric Vehicle (EV) technology is a promising way to reduce petroleum consumption as well as reduce environment pollution. The energy supply strategy is crucial to promote the application of battery EVs. Recently, the key restrict of EVs´ promotion and development has been lacking of charging and exchanging station for EVs with rapid development on EVs. This paper expounds the design and realization of automatic monitoring system (AMS) for charging and exchanging station for EVs which is based on CAN communication. The AMS adequately the system requirements of battery charging and exchanging, therefore, the prime design goals of AMS compose of two aspects: 1) voltage monitoring for battery stack while exchanging; 2) current monitoring for battery stack while charging. As a result, it is potentially very attractive for EVs´ promotion, as it can lead to an efficient and low cost implementation. The results of this paper are of great importance to improve the energy supply system and guide the upcoming rigorous construction of energy supply facilities for EVs. We believe the proposed AMS will be used widely with the rapid development of EVs.
