Abstract
A method and system for conditioning an energy storage system (ESS) for a vehicle, like a high-voltage battery or a fuel cell used for vehicle propulsion. It may be detrimental for a high-voltage battery in a parked vehicle to be exposed to extreme temperatures for an extended period of time. Thus, the method and system may be used to condition such a battery—for example, by heating it up if it is too cold or by cooling it down if it is too hot—so that the performance, durability, lifespan and/or other aspects of the battery are improved. In an exemplary embodiment, the method predicts if the battery will need conditioning the next time the vehicle is parked and, if such conditioning is needed, then the method predicts if the battery has sufficient charge to perform this conditioning. If the charge appears insufficient, then the method operates an energy generator that provides additional charge to the battery in anticipation of the needed conditioning.
