摘　　要：对电池组并联时环流产生的原因进行分析,并对环流现象提出了三种解决方案,即预充电阻解决方案、二极管解决方案和DC-DC转换器解决方案,最终对三种方案进行了对比。The cause of circulating current which happened in the battery pack in parallel was analyzed, and three schemes of restraining circulating current： prefilled resistance, two-electrode valve and DC-DC converters, were proposed. At last, three kinds of schemes were compared.
