A power supply apparatus for a hybrid vehicle, the power supply apparatus comprising:
- a battery unit including a plurality of battery cells configured to store different levels of power;
- and
- a power control unit configured to control the battery unit to integrally or selectively output the power of the plurality of battery cells based on whether an engine of the hybrid vehicle generates power.
A power supply method for a hybrid vehicle including a battery unit and a power control unit, in which the battery unit includes a plurality of battery cells storing different levels of power, the power supply method comprising:
- controlling, by the power control unit, the battery unit to integrally output the power of the plurality of battery cells when an engine of the hybrid vehicle is started;
- and
- controlling, by the power control unit, the battery unit to selectively output the power of the plurality of battery cells when the engine of the hybrid vehicle generates power.
