炭材料对低速纯电动车用铅酸电池低温性能的影响

Influences of carbon material on the low temperature performances of lead-acid batteries for low speed electric vehicles

在低温条件下,传统用于低速纯电动车用的动力铅酸电池难以满足使用要求。在负极活性物质中添加复合炭材料,可以显著提高蓄电池的低温充电接受能力和循环性能,在实验室测试和实车测试中均表现出优异的性能。

The conventional lead-acid batteries do not deliver satisfactory performance in low speed electric vehicles （LSEV） at low temperature. With the addition of a certain amount of carbon material in the NAM, however, the charge acceptance and cycling endurance of the batteries at low temperatures can be signifcantly enhanced and perform well in both laboratory and in-vehicle tests.
