A power supply apparatus for an electric vehicle includes a main battery, a sub-battery of lower voltage, a first output circuit unit including a first output sub-unit and a second output sub-unit, a control circuit unit, and a second output circuit unit including a third output sub-unit. The first output sub-unit receives electrical power from an external power supply and outputs first electrical power for main battery charging. The second output sub-unit receives electrical power from the power supply and outputs second electrical power for sub-battery charging. The control circuit unit individually controls charging of the main battery and the sub-battery by the first electrical power and the second electrical power respectively. The third output sub-unit receives electrical power from the power supply, via a different pathway compared to the first and second output sub-units, and outputs third electrical power for driving the control circuit unit. |
