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: A battery module includes a first load terminal, a second load terminal, a load enable terminal, and a battery having a first battery terminal coupled to the first load terminal. A first protection circuit includes a first isolation device coupled between a second battery terminal of the battery and the second load terminal of the battery module. The first protection circuit further includes a first sensing circuit configured to measure a battery parameter and control the first isolation device based on the battery parameter. A driver circuit is coupled between the first battery terminal and the first protection circuit. The driver circuit is configured to control power to the first protection circuit based on a load enable signal asserted at the load enable terminal. A bypass circuit is coupled between the second battery terminal and the second load terminal.
