Optionally, if the working state of the power generation device is abnormal, the electricity price state of the power grid system is the valley electricity price, and the power grid system is determined to be the second target charging device.
Specifically, this embodiment can determine whether the energy storage device needs to be charged, and if the energy storage device needs to be charged and the operating state of the power generation device is abnormal, the electricity price state of the power grid system is the valley electricity price, and it is determined that the power grid system is the second target charging device, even if the power grid system supplies power to the energy storage device alone.
