你做电池异常过充，应该是空电池吧
Overcharging of a rechargeable battery. The battery is charged under each of the
following conditions in turn.
• The battery charging circuit is adjusted with the battery disconnected to give 106 % of
the rated output voltage of the charger, or the maximum charging voltage available
from the charger (without simulation of faults), whichever is the higher attainable
value. The battery is then charged for 7 h.
' v' F! g* `* X! Z• The battery charging circuit is adjusted, with the battery disconnected, to 100 % of the

circuit and that results in overcharging of the battery. To minimize testing time, the
failure is chosen that causes the highest overcharging current. The battery is then

这个测试对于可充电电池来说，是要在饱和状态下做的。
