基于电动车用蓄电池荷电状态估测的充电方法

摘要

The research on fast-charging method of battery was mainly proposed. An charging method———State-of-Charge ( ) for the battery was put forward. The efficient battery charging method was required to reduce the charging time and prevent the overcharging. However, it takes a long time for ful y charging the battery. So the improved CC-CV charging method was presented. Advantages of three-phase AC-DC boost converter and combine with for charging the battery were taken. The total charging time was reduced. The power capacity of the battery for EV was met. It was compared to the conventional CC-CV method, and the relative accuracy of through the experimental results was verified.%主要对电动汽车用蓄电池的快速充电展开研究，提出了一种蓄电池荷电状态估测的充电方法。电池的有效充电要求减少充电时间并防止发生过充，然而给电池充满电需要花费很长时间，所以给出了改进的恒流-恒压(CC-CV)快速充电方法，利用三相AC-DC升压整流器及结合对电池充电。该方法减少了总充电时间，满足了电动汽车用电池的大功率强度。通过实验结果将此方法与传统的CC-CV法进行比较，从而验证了的相对精确性。
