Abstract

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.

Claims

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.

2. A method for incipient drive of a slow charger for a green vehicle, the method comprising:

operating, by a controller, a regulator by outputting a control pilot (CP) signal from electric vehicle supply equipment (EVSE);

operating, by the controller, a flip-flop by outputting a driving signal from the regulator;

operating, by the controller, a switching mode power supply (SMPS) by outputting a driving signal from the flip-flop; and

resetting, by the controller, the flip-flop by outputting a reset signal from a central processing unit (CPU) turned on by the SMPS.

3. The method of claim 2, further comprising, apply, by the controller, a power latch signal to the SMPS before outputting the reset signal to maintain power of the SMPS.

4. A non-transitory computer readable medium containing program instructions executed by a processor or controller, the computer readable medium comprising:

program instructions that operate a regulator by outputting a control pilot (CP) signal from electric vehicle supply equipment (EVSE);

program instructions that operate a flip-flop by outputting a driving signal from the regulator;

program instructions that operate a switching mode power supply (SMPS) by outputting a driving signal from the flip-flop; and

program instructions that reset the flip-flop by outputting a reset signal from a central processing unit (CPU) turned on by the SMPS.
