ABSTRACT:
A method and system for enhanced battery control improves the performance of a hybrid electric vehicle (HEV). The HEV includes an internal combustion engine, at least one motor operable as a generator and a battery. A hybrid control module determines various discharge and recharge allowances limiting operation of the battery with different operating conditions of the hybrid electric vehicle. It also determines various periods of time limiting operation of the battery with different operating conditions of the hybrid electric vehicle. The allowances and periods of time may be used as limits that are imposed on commands for the motor.
