A battery discharge device according to an exemplary aspect of the present disclosure includes, among other things, a sensor configured to sense a parameter of a high voltage source, a controller in communication with the sensor and a discharge circuit that discharges energy stored on the high voltage source in response to a command signal from the controller. The discharge circuit includes a plurality of resistors connected in parallel to one another.

Battery discharge device with self-adjusting resistance

A battery analysis system includes a control module, a measurement module, and a pulse power module. The control module controls current to a battery to one of charge and discharge the battery. The measurement module determines N voltages across the battery at N times during a period when the control module controls the current and when the battery is at a predetermined temperature and a predetermined state of charge. N is an integer greater than 1. The pulse power module determines N resistances corresponding to the current and the N voltages across the battery and determines a pulse power value of the battery based on the N resistances. The pulse power value indicates a dynamic power of the battery to one of charge and discharge.
