Patent attributes
A battery charging system includes a charger that is configured to charge and discharge a battery. The battery system further includes a controller programmed to operate the charger based on a state of charge of the battery to, during a storage duration, maintain the state of charge at a partial charge level. The charger may be operated to charge and discharge the battery during the storage duration. Upon expiration of the storage duration, the controller operates the charger to maintain the state of charge at an operating charge level. The partial charge level is selected to reduce an amount of degradation to the battery relative to the operating charge level for a same duration of time. The battery charging system includes remote connectivity such that the storage duration may be modified during the storage duration from a remote device.
