    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.
