1. An electrical vehicle charging system consisting essentially of:

  • an enclosure including a power converter unit capable of receiving incoming power from a remotely located main circuit breaker and converting said incoming power to a selected DC voltage and current levels to charge at least one battery of said electrical vehicle, said enclosure being mounted on a foundation which is fixedly secured to the ground, said enclosure having one proximity sensor mounted to each of two opposing walls therein, said proximity sensors monitoring the presence of two respective targets, said targets being mounted onto said foundation, said proximity sensors each inputting a signal to control circuitry contained within said enclosure, said signals informing said control circuitry of the presence or absence of said targets, said control circuitry sending a trip signal to a remotely located shunt trip main circuit breaker in a situation wherein one or both of said proximity sensors senses that no target is present, thus causing a selected one of said main circuit breaker or said remotely located shunt trip main circuit breaker to trip removing power from said enclosure.
