confirmed for activation.
6.7.6 The charger shall have soft-start function, AND the soft-start time is 3 s
~ 8 s.
6.7.7 In the charging process, the charger shall ensure that the battery’s
charging voltage and charge current do not exceed the allowable value.
6.7.8 In the charging process, when the temperature of the battery exceeds
the allowable limit, the charger shall stop charging.
6.7.9 Only after the charger is correctly connected to the battery system of
the electric vehicle, it is allowed for the charger to start the charging process;
when the charger detects abnormal connection to the battery system of the
electric vehicle, it must cut off the DC output immediately.
