  • Patent number: 11639116
    Abstract: 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.
