Test procedure
测试步骤
Each cell shall be forced discharged at ambient temperature by connecting it in series with a
12V D. C, power supply at an initial current equal to the maximum discharge current
specified the manufacturer The specified discharge current is to be obtained by connecting
a resistive load of the appropriate size and rating in series with the test cell, Each cell shall
be forced discharged for a time interval(in hours) equal to its rated capacity divided by the
initial test current(in ampere).
在 20±5℃的环境温度下，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
供每个电芯初始电流为制造厂指定的最大放电电流，放电时间为额定容量除以初始电流。
