Methods and apparatus for use with electric vehicles

Abstract

An electric vehicle supply equipment system for electric vehicle charging/discharging is provided and comprises an electric vehicle supply equipment that is connectable to a distributed energy resource for charging/discharging a battery of an electric vehicle and a controller in operative communication with at least one of a communication network, an electronic device of the electric vehicle, or a distributed energy resource controller for transmitting and receiving electric vehicle supply equipment information that provides the EVSE with a capability to directly (e.g., using current measurement inputs) or indirectly (e.g., using communication protocols to a remote measurement device) measure a net current being imported from or exported to a grid. Thereafter, the EVSE can use one or more control systems (e.g., an integral power control system (PCS)) to increase and/or decrease the charging and/or discharging rate of the EV to prevent overload of a service transformer.
