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 method and apparatus for a battery protection circuit. One embodiment provides a method for protecting a battery including receiving, with a comparator, a first voltage, the first voltage including a switch voltage across a current limiting switch provided on a current path of a battery and coupled to a current limiting control circuit to limit current output by the battery. The method also includes receiving, with the comparator, a reference voltage and comparing, with the comparator, the first voltage and the reference voltage. The method further includes controlling, with the comparator, a control switch to open when the first voltage exceeds the reference voltage.

Abstract: Methods and apparatus for a protection circuit for a battery and a battery connected device during charging are provided. In one embodiment, the apparatus includes a load-blocking switch connected between a rechargeable battery and an electronic device and a charge-blocking switch connected between the rechargeable battery and a charger. The apparatus also includes a safety circuit to detect a voltage across and the current flowing through the rechargeable battery. The safety circuit opens the load-blocking switch and the charge-blocking switch when it detects that the voltage across or the current flowing through the battery exceeds a predetermined threshold.
