Abstract
A direct current fast charge (DCFC) system and associated method that lower standby power dramatically when the DCFC system is not in operation, and that provide a reset capability for communication needs. The DCFC system utilizes an appropriate load disconnection switch and an associated control and communication circuit, timer circuit, and automatic turn on system. This improves the reliability of the electronics by removing voltage stress during the standby mode. The DCFC system prevents energy waste, and therefore provides a “green” alternative to conventional DCFC systems.
