Abstract: An electric power system includes a vehicle on which a power storage device is mounted, a charging and discharging system that exchanges electric power between the vehicle and a facility external to the vehicle, a photovoltaic power generation device that supplies electric power generated using sunlight to the charging and discharging system, and a controller that stops the charging and discharging system based on any of a first condition, a second condition, and a third condition. The first condition is related to the amount of electric power exchanged between the power storage device and the facility, the second condition is related to a time when the power generated by the photovoltaic device is less than a threshold, and the third condition is related to an electricity rate.

Abstract: A system for charging an electric vehicle in a facility includes a current sensor adapted to obtain an input current signal for a power source in the facility. An electric vehicle supply equipment (EVSE) is configured to charge the electric vehicle through the power source based at least partially on a control pilot signal. A controller has a processor and tangible, non-transitory memory on which instructions are recorded for dynamically adjusting the control pilot signal based on the input current signal. The control pilot signal is set to a predefined maximum when the input current signal is less than a main circuit breaker rating of the facility. The controller is configured to reduce the control pilot signal from the predefined maximum when the input current signal is at or above the main circuit breaker rating.
