switch, the vehicle can only be charged with single-phase AC. The actual charging
current of the vehicle is not more than 8 A;

current of each live conductor shall not exceed 30 A (r.m.s.). The absolute value
of the current peak shall not exceed 42.4 A. When the requirements of GB/T
17625.2 or GB/T 17625.7 are met, the current peak may exceed 42.4 A. Event 2
shall not exceed 1 s.
NOTE 1: The purpose of limiting the event 2 inrush current is to prevent the miniature circuit
breaker (MCB) from tripping. The 30 A (r.m.s.) current value corresponds to the B-type MCB with
a rated current of 10 A as specified in GB/T 10963.1.
NOTE 2: The inrush current is generated by the following two phenomena: During event 1, the
inrush current is generated by the EMC filter upstream of the charger power module;...
