Abstract: This disclosure relates to systems and methods for charging a battery. An example embodiment includes receiving information about an initial state of charge of a battery. If an initial state of charge is less than a predetermined threshold and if a charger is electrically coupled to the battery, a charger may be configured to charge the battery according to a preferred charge rate higher than a default charge rate. A charging duration is determined based on a type of the battery, the initial state of charge, a target state of charge, and the charge rate. A controller may determine a partial charge condition based on at least one of: providing electrical current to the battery at the charge rate for the charging duration or receiving information indicative of a state of charge of the battery reaching the target state of charge.
