图 1 温度循环流程示意图
Charge the battery per section 4.4 and place the battery at
25℃±2 ℃ temperature control chamber and go through
the following steps （see figure 1）:
a) Place the battery at 75 ℃ ±2 ℃ test chamber and
maintain for 6 hours.
b) Decrease the test chamber temperature to -40℃±2℃
and maintain for 6 hours.
c) The temperature transition time is no greater than 30
minutes.
d) Repeat step a to step b, cycle 10 times in total.
