Current monitoring and limiting apparatus, system and method for electric vehicle supply equipment

摘要

An electric vehicle charging system is disclosed. More particularly, the system encompasses a load center having one or more electrical loads coupled thereto, electric vehicle supply equipment (EVSE) to charge an electric vehicle (EV), and a monitoring and limiting device (MLD) to monitor power or current usage of at least the one or more loads coupled to the load center, and adjust a charging level setting of the EVSE based upon the level of the usage. MLD apparatus and methods of charging a vehicle with electric vehicle supply equipment (EVSE) are provided, as are other aspects.
