1. A power system comprising:
a bidirectional power transfer inverter configured to receive grid power and be electrically connected with electric vehicle supply equipment;
an auxiliary battery electrically connected with the bidirectional power transfer inverter and configured to supply power to the bidirectional power transfer inverter and electric vehicle supply equipment;
a storage battery electrically connected with the bidirectional power transfer inverter and
one or more controllers programmed to, after activation of control circuitry of the bidirectional power transfer inverter using power from the auxiliary battery while the grid power is unavailable, ramp down the power from the auxiliary battery and ramp up power to the bidirectional power transfer inverter from the storage battery or from a traction battery of an automotive vehicle electrically connected with the electric vehicle supply equipment.
