Apparatus, system and method of ac and dc v2x and smart charging using a bidirectional electric vehicle supply equipment

A power distribution system comprising:

• an electric grid;
• an electric vehicle (EV);
• a plurality of loads;
• a control panel connected to the electric grid and including a grid smart circuit breaker structured to connect and disconnect the electric grid from the loads, an EV smart circuit breaker structured to connect and disconnect the EV from the loads and/or the electric grid, and load smart circuit breakers structured to connect and disconnect the loads from the electric grid and/or the EV;
• a bidirectional EV supply equipment (EVSE) comprising:
• 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 interrupt current flowing to the loads, the EV and/or the electric grid in an event of fault;
• an EVSE backup control power structured to provide control power to the bidirectional EVSE when the electric grid is not available or power from the EV is not available;
• and
• a bidirectional EVSE communications controller structured to communicate with the EV, the control panel and an aggregator during selecting an operation mode, transitioning to a selected operation mode and performing the selected operation mode;
• and
• the aggregator communicatively coupled to the bidirectional EVSE and structured to monitor and manage the operations of the EV and the bidirectional EVSE.

A method of providing power to loads in a power distribution system including an electric grid, an aggregator, a control panel, an electric vehicle (EV) coupled to a smart inverter, and loads, the method comprising:

• providing a bidirectional EV supply equipment (EVSE) structured to be coupled to the EV via an EV connector and the loads via the control panel, the bidirectional EVSE comprising (i) a voltage sensor structured to sense grid voltage and EV voltage;
• (ii) an EVSE smart circuit breaker coupled to the voltage sensor, connect or disconnect the EV based on a signal from the voltage sensor and interrupt current flowing to the loads, the EV and/or the electric grid in an event of fault;
• (iii) an EVSE backup control power structured to provide control power to the bidirectional EVSE when the electric grid is not available or power from the EV is not available;
• and (iv) 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 the selected operation mode;
• determining that an EV is connected to the bidirectional EVSE;
• determining that the electric grid is not available based on the determination that the EV is connected to the bidirectional EVSE;
• selecting an operation mode based on the determination that the electric grid is not available;
• transitioning to a selected operation mode;
• and
• performing the selected operation mode.
