ELECTRIC VEHICLE STATUS DARK START CHARGE

A home energy system includes a combiner box with a power source and a microprocessor. The microprocessor maintains a first target state of charge for the power source using power from a traction battery of an electric vehicle when the vehicle is powering a home. When the system detects that the vehicle will stop powering the home, the microprocessor charges the power source from the traction battery to reach a second target state of charge.
