Abstract
The first battery is configured to be charged and discharged with a larger current than the second battery. The second battery has a higher storage capacity than the first battery. When the voltage of the second battery is lower than the voltage of the first battery, the controller allows charging of the second battery through the second relay while prohibiting charging of the first battery through the first relay until the voltage of the second battery reaches the voltage of the first battery.
