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. 120-. (canceled)21.

A power-supply-side filter circuit includes a reactor and a capacitor, which are connected in series between the AC power source and the power-supply-side coil. A power-receiving-side coil is interlinked with a magnetic flux produced by the power-supply-side coil to produce an alternating current. The power-supply-side filter circuit, the power-supply-side capacitor, and the power-supply-side form a circuit having an impedance having a frequency characteristic, in which a frequency of a minimum point formed on a high-frequency side relative to a maximum point is greater than a frequency of a fundamental wave of an alternating current supplied from the AC power source and is less than a frequency of a third order wave of the fundamental wave.

A multi-voltage electrical system of a motor vehicle includes first and second subsystems operable at operating voltages, where a current is selectively and alternatively feedable from the first subsystem into the second subsystem and from the second subsystem into the first subsystem, and an electrical consumer is coupleable to and decoupleable from the first subsystem. A method for operating the system includes, responsive to a failure or lack of an attenuator, implementing a special operating mode in which negative and positive sudden load variations caused by coupling or decoupling of the electrical consumer is counteracted by, respectively, feeding current from the second subsystem into the first subsystem or vice versa, in each case over a respective feed time period.

An electric power supply device for a vehicle includes an electric storage device, a boost converter, and a controller. The boost converter boosts voltage of the electric storage device and supplies the boosted voltage to an electric load of the vehicle. The controller controls the boost converter in a continuous boost mode and an intermittent boost mode. The continuous boost mode is a mode in which the boost converter is in continuous operation. The intermittent boost mode is a mode in which the boost converter is in intermittent operation. The controller more restricts a charge/discharge demand of the electric storage device such that a charge/discharge demand of the electric storage device at a time when the boost converter is operated in the intermittent boost mode is more restrictive than a charge/discharge demand of the electric storage device at a time when the boost converter is operated in the continuous boost mode.
