Title:
CHARGING CURRENT CONTROL METHOD FOR REDUCING CHARGING TIME OF ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2024/096272
Kind Code:
A1
Abstract:
A charging current control method for reducing the charging time of an electric vehicle, according to the present invention, comprises the steps of: monitoring the charging voltage and a first actual charging current of an electric vehicle; comparing the first actual charging current of the electric vehicle with a reference current that can be supplied by an electric vehicle charger; changing, by a predetermined value, the first charging-permitted current of the electric vehicle charger supplying a charging current to the electric vehicle, if the first actual charging current of the electric vehicle and the reference current of the electric vehicle charger are different; and transmitting, to the electric vehicle, a second charging-permitted current changed by the predetermined value, and measuring the second actual charging current of the electric vehicle according to the second charging-permitted current and comparing same with the reference current. Therefore, the present invention can shorten the charging time of an electric vehicle and improve the charging efficiency of an electric vehicle charger, and thus can solve deficiency problems of charging equipment.
