Abstract
In a power supply system, a charge switching unit is relays switchable between a series circuit that connects a first high-voltage battery to a second high-voltage battery in series and a parallel circuit that connects the first high-voltage battery to the second high-voltage battery in parallel. If an input voltage is a first voltage (for example, approximately 400 V), a controller controls the charge switching unit to form the parallel circuit, and charges the first and second high-voltage batteries with power supplied from a quick charger. If the input voltage is a second voltage (for example, approximately 800 V) higher than the first voltage (for example, approximately 400 V), the controller controls the charge switching unit to form the series circuit, and charges the first and second high-voltage batteries with power supplied from a super-quick charger.
