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.
