Abstract: A bidirectional electric vehicle supply equipment (EVSE) for use in a power distribution system having an EV, an electric grid, a control panel and an aggregator or grid operator. The bidirectional EVSE includes a voltage sensor structured to sense grid voltage and EV voltage; an EVSE smart circuit breaker coupled to the voltage sensor and structured to connect or disconnect the EV based on a signal from the voltage sensor and to disable a PWM signal before opening EVSE contactors, an EVSE backup control power structured to provide control power to the bidirectional EVSE when the electric grid is not available; and a bidirectional EVSE communications controller structured to communicate with the EV, the control panel and the aggregator during selecting an operation mode, transitioning to a selected operation mode, and performing operation and oversight protection in the selected operation mode.

Abstract: A smart load control system includes: a neutral forming auto-transformer (NFT) structured to form a neutral line; a plurality of smart circuit breakers (SCBs) including an islanding and grid-connecting device (IGD) coupled to the electric grid and an EV SCB coupled to the bidirectional EV charger, the IGD structured to sense grid voltage and switch ON and OFF the electric grid, the EV smart circuit breaker structured to sense EV voltage and switch ON and OFF the bidirectional EV charger; and a building energy system manager communicatively coupled to the plurality of SCBs and structured to collect data from each SCB, the data including at least the grid voltage and the EV voltage, select one of grid-connected mode or islanded mode based on the grid voltage and the EV voltage, perform a safe transition to the selected mode, and monitor the grid voltage and the EV voltage.
