Abstract: A method and apparatus for a battery protection circuit. One embodiment provides a method for protecting a battery including detecting, with a voltage divider having a first resistor and a second resistor connected in series, a voltage across a first current limiting switch and a second current limiting switch provided on a current path of a battery. The method also includes providing, with a control output provided between the first resistor and the second resistor of the voltage divider, a control signal to the first current limiting switch, wherein the control signal opens and closes the first current limiting switch. The method further includes controlling, with the voltage divider, the first current limiting switch to open when the voltage across the first current limiting switch and the second current limiting switch exceeds a predetermined threshold.

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.

IPC: H02J7/00
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.

Abstract: Embodiments include a rechargeable battery pack, system, and power adapter that allow the rechargeable battery pack to both power a host device though a set of host contacts and provide power, through the power adapter, via a set of charging contacts that interface with the power adapter. The power adapter contains a voltage source which activates a control circuit to disable a discharge protection circuit in the battery pack to allow current to discharge through the charging contacts.
