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: An internal charging system controls charging of a battery used to power an electronic device when an external power source is connected to the device. The internal charging system can charge a battery that has a higher operating voltage than the voltage provided by the external power source. While charging the battery from the external power source, an internal charge controller can operate and inhibit functions of the device to indicate to user that a charging operation is commencing, and to prevent operation of the device when the battery voltage is too low to support such operation.

Abstract: Embodiments for a battery charger include a single conversion switched mode power supply having a bias winding on the primary side of the power transformer. The bias winding produces an output that is proportional to the voltage produced on the secondary winding, and is sensed by a programmable voltage sensing circuit. The programmable voltage sensing circuit is programmed by a voltage select signal from the secondary side of the charger to produce an sense signal that is proportional to the output of the bias winding by a selected factor corresponding to a battery type of a battery being charged.

Abstract: Disclosed herein are methods and systems for contactless battery discharging. One embodiment takes the form of a contactless power-transfer system that includes a wireless-communication interface, a controller connected to the wireless-communication interface, a magnetic-resonance circuit, a power-conditioning circuit connected to the magnetic-resonance circuit, and a load element connected to the power-conditioning circuit. The controller is configured to determine that a smart-battery system is in a discharge-needed state and responsively transmit, via the wireless-communication interface, a battery-discharge command instructing the smart-battery system to generate an oscillating magnetic field. The magnetic-resonance circuit is configured to couple with the generated oscillating magnetic field and responsively output a corresponding power signal. The power-conditioning circuit is configured to receive the power signal from the magnetic-resonance circuit, rectify the received power signal, and output the rectified power signal. The load element is configured to receive the rectified power signal from the power-conditioning circuit.
