An electric power supply system is to be included in a hybrid electric vehicle that is provided with a driving motor and an engine and is configured to switch between an HEV traveling mode of traveling by causing both the driving motor and the engine to operate and an EV traveling mode of stopping the engine and traveling with motive power of the driving motor. The electric power supply system includes a main battery, an electric power generator, a sub-battery, and a control apparatus. The main battery supplies electric power to the driving motor. The electric power generator generates electric power upon receiving motive power outputted from the engine. The sub-battery is charged with the electric power generated by the electric power generator. If an abnormality is diagnosed as being present in the sub-battery, the control apparatus disables the HEV traveling mode and enables the EV traveling mode.
