Title:
FORWARD COMPATIBILITY METHOD AND CIRCUIT FOR DIRECT-CURRENT CHARGING CONTROL CIRCUIT OF ELECTRIC VEHICLE, AND CONVERTER
Document Type and Number:
WIPO Patent Application WO/2022/036935
Kind Code:
A1
Abstract:
A forward compatibility method and circuit for a direct-current charging control circuit of an electric vehicle, and a converter. The method comprises: arranging equivalent resistors (Rd, R', Rc', Rc") on a CC1 loop and/or a CC2 loop; on the side of an electric vehicle, determining the type of a charger by means of monitoring the voltage on a CC2 line, and performing a charging flow according to the type of the charger; and on the side of the charger, by means of monitoring the voltage on a CC1 line, determining whether the charger is reliably connected to allow safe charging. An electric vehicle can be charged with all common chargers in the market, thereby realizing forward compatibility of a direct-current charging control guiding circuit.
