Abstract: A method for charging a battery includes detecting, with an electronic processor, a presence of the battery coupled to a charging interface. The method includes receiving, with the electronic processor, a command, the command including a charge mode. The method includes, in response to receiving the command, controlling a charging circuit coupled to the charging interface to charge the battery to a predetermined level based on the charge mode. The method includes, when the battery reaches the predetermined charge level, sending a battery control command, based on the charge mode, to control an active limiting circuit of the battery via a single wire data line coupled to the charging interface.

Abstract: Embodiments include a modular battery charger having a main charging source and is configured to include at least one additional charging source that can be an auxiliary charging source or an external charging source. The additional charging sources can be added as modules to augment the total charging current that can be provided to a rechargeable battery. The modular battery charger can selectively enable or disable the additional charging sources while controlling the output current of the main charging source to adjust the charging current provided to a rechargeable battery.

Abstract: A method and apparatus for determining the condition of a rechargeable battery determines a dynamic impedance of the battery while discharging the battery, and determines a battery condition category based on the dynamic impedance. The battery can be discharged in a manner that recovers the stored energy being discharged from the battery.
