Hybrid electric vehicle battery charge reduction for improved cooling performance

摘要

Systems and methods are provided for vehicle battery charge reduction. A hybrid electric vehicle is disclosed. The vehicle comprises an internal combustion engine; an electric motor; a battery electrically coupled to the electric motor; a battery charger electrically coupled to the battery and mechanically coupled to the internal combustion engine; one or more sensors, wherein each sensor provides a respective sensor signal, wherein each sensor signal represents a respective current operating condition of the hybrid electric vehicle; and a computing component configured to: perform a first comparison of a state-of-charge of the battery to a charge threshold, perform a second comparison of one or more of the current vehicle operating conditions to respective nominal vehicle operating conditions, wherein none of the vehicle operating conditions describe a condition of the battery, and reduce charging of the battery based on the first comparison and the second comparison.
