上海交通大学工程硕士学位论文 上海交通大学工程硕士学位论文 万方数据 万方数据 Various charing methods for lead-acid battery were used to shorten the charging time. However, the fact is almost all the lithium ion battery using the traditional ‘constant current,then constant voltage with taper current’ method. This paper described the charging test on a LiFePO4 battery. Analyized over 800 charging curves in its life cycle test, demonstrated the battery SOC characteristics and range of error. Proposed the idea to calibrate the battery SOC using some specific range of battery charing loaded voltage. Finally, discussed the needs for PHEV external charging facilities,including: various factors to affect charging speed, the demand for external power, charging interface standardization, and the prospects for intelligent charging.
