System and method for incipient drive of slow charger for a vehicle with electric motor

摘要

Disclosed herein is a system and method for incipient drive of a slow charger for a vehicle. Specifically, an incipient drive entry of the slow charger used when a battery is charged in an electric vehicle (EV) or a plug-in hybrid electric vehicle (PHEV) may be performed. The method includes operating, by a controller, a regulator by outputting a control pilot (CP) signal from electric vehicle supply equipment (EVSE). Additionally, the method includes operating, by the controller, a flip-flop by outputting a driving signal from the regulator and operating a switching mode power supply (SMPS) by outputting a driving signal from the flip-flop. The method further includes resetting, by the controller, the flip-flop by outputting a reset signal from a central processing unit (CPU) turned on by the SMPS.

主权项

1. A system for incipient drive of a slow charger for a vehicle, the system comprising:
a regulator configured to operate in response to a control pilot (CP) signal received from electric vehicle supply equipment (EVSE); a flip-flop configured to operate in response to a drive signal received from the regulator; a switching mode power supply (SMPS) configured to operate in response to a drive signal received from the flip-flop; and a central processing unit (CPU) configured to be turned on by the SMPS and to reset the flip-flop, wherein the CPU is configured to apply a power latch signal to the SMPS before resetting the flip-flop to maintain power of the SMPS.
