T.8 Forced discharge
强制放电
Test Method 测试方法
Each cell was forced discharged at ambient temperature by connecting it in series with a 12 V DC power
supply at an initial current equal to the maximum discharge current specified by the manufacturer.
在常温环境下，将单个电芯连接在12V的直流电源上进行强制放电，此直流电源提供给每个电芯初始电流为
制造厂指定的最大放电电流。
The specified discharge current was obtained by connecting a resistive load of the appropriate size
and rating in series with the test cell. Each cell was forced discharged for a time interval (in hours) equal
to its rated capacity divided by the initial test current (in amperes).
指定的放电电流通过串联在测试电芯上的合适大小和功率的负载来获得，每个电芯的强制放电时间（小时）
为额定容量除以初始电流（安培）。
