The overvoltage varies inversely with the current density to some extent . 超电压在某种程度上随电流密度成反比地变化。
this value △ vipo is equivalent to an overvoltage caused by the ip phenomenon. Vipo这个值相当于由IP现象引起的过电压。
On charge, the counter-voltage or overvoltage of the battery could be so high as to restrict the charging characteristics at low temperatures . 充电时，蓄电池的反电压或过电压太高，以致限制了低温充电性能。
3 . protected from overvoltage , it is safe and credible 3过压力保护，安全可靠。
