  "textContent": "In a power supply device, switching section switch a connection between batteries to a series connection or a parallel connection. In a case where the connection between the batteries is switched from the series connection to the parallel connection to charge the batteries by as external charger, a controller does not switch the connection to the parallel connection, does not charge one battery having a larger voltage out of the batteries, and separately charges the other battery when a potential difference between a voltage of the battery and a voltage of the battery is a predetermined threshold value or higher; and the controller switches the connection to the parallel connection and charges the batteries when the potential difference is lower than the threshold value.",
