电池与超级电容器单体电压均衡电路综述

Voltage unbalances of the series-connected battery and supercapacitor (SC) cells are mainly due to their differences in materials, manufacturing technology, internal specifications, temperature, initial charge, etc. This voltage difference can reduce the battery or SC pack capacity, stored energy, efficiency, and lifespan. Various methods have been proposed to overcome this issue to avoid its disa...
