Moreover , it provides them both while it is discharging and while it is being re-charged .

而且，在其充电和放电的模式下都可正常工作。

Discharging occurs when the electrons are given a path to flow to the other side-in other words , when balance is restored .

当电子获得路径移动至另一端的时候，换句话说，当平衡被恢复的时候，就形成了放电。

And that does not count related parts like the system that maintains the temperature of the cells within an acceptable range and manages the charging and discharging .

这还不包含相关的零部件，如将电池片温度维持在可接受范围内和管理充放电的系统。

When it is discharging , the ions flow back and in the process cause a current to flow in an external circuit attached to the battery .

放电时，离子回流，这个过程中会在连接到电池的外部电路中产生电流。

Joel schindall , another professor in mit 's lees and associate director of the lab , explained that during discharging , the charge on the plates decreases as electrons flow through an external circuit .

麻省理工学院电磁和电子系统试验室的另一名教授兼试验室的副主任joelschindall解释说，在放电期间，金属片上的电荷随电子流经外部回路而减少。
