ABSTRACT:
A hybrid electric vehicle includes a lead-acid traction battery made up of a plurality of series-connected modules. During operation of the vehicle, the traction battery is discharged for acceleration, and charged by an ancillary power source. To maximize the capacity of the traction battery to accept regeneration charge current from dynamic braking, and to produce useful traction motor current, the modules of the traction battery are equalized during normal operation of the hybrid electric vehicle.
