An electric powered vehicle is equipped with a main battery for storing electric power input to and output from a motor, and an auxiliary battery as a power source for an auxiliary system including a control system. A DC/DC converter converts an output voltage of the main battery to a level of an output voltage of the auxiliary battery. During operation, a BAT-ECU monitors states of charge of the main battery and the auxiliary battery and controls operation/stop of the DC/DC converter. When the electric powered vehicle is in a key-off state (running stop state), the BAT-ECU is intermittently operated, while an external charging system and a vehicle running system are stopped.

The present invention is to provide an equalizing method and an apparatus thereof for preventing unit cells from being over charged and discharged. After an ignition switch is turned off, CPU checks a voltage of a main battery and judges whether the main battery is in a state of equilibrium or not. When the main battery is in the state of equilibrium, the CPU controls a first and second switch groups to equalize voltages of unit cells included in the main battery by repeating a charge transfer from a maximum voltage cell to a minimum voltage cell for a predetermined period of time.

An ECU in an electric power system for a vehicle controls a DC-DC converter so that an alternator transmits a residual generated electric power to a sub battery while a terminal voltage of a main battery is maintained within an optimally specified voltage range. This residual generated electric power is obtained by subtracting from a maximum generating electric power of the alternator an electric power to be consumed by electric loads and an electric power with which the main battery is charged. This can suppress any fluctuation of the voltage of electric power of the electric power system, namely, the output voltage of the alternator and the voltage of the main battery, and perform a maximum regenerative electric power generation. The sub battery is efficiently changed with the regenerative electric power.

A power delivery system for an electric vehicle provides efficient power management for either continuous or intermittent high-performance operation, using a boost stage and an on-board charging circuit. A main battery, configured as a high-capacity power source, supplies power to the electric motor under normal load conditions. An auxiliary boost battery assists the main battery in supplying a high-level current at a higher discharge rate thereby causing the motor to operate in a high-performance drive mode. A charging circuit recharges the boost battery from the main battery during operation of the motor. The charging circuit also maintains a charge balance between the boost battery and the main battery when the two batteries have different chemistries. In one embodiment, participation of the boost battery in powering the electric motor can be controlled automatically according to sensed changes in the load. In another embodiment, power management can be based on timed intervals.

DC/DC converter is connected directly to a main battery with no system relays intervening therebetween. The DC/DC converter drops and then supplies the voltage of a power supplied from the high voltage main battery to a subsidiary battery. A DC/DC converter control circuit receives a supply of the power from the main battery to control the dropping operation of the DC/DC converter. Even when the subsidiary battery goes dead, the DC/DC converter is responsive to a control signal outputted from the DC/DC converter control circuit using, as its power supply, the main battery, to perform a boosting operation, thereby quickly charging the subsidiary battery.
