Abstract
A circuit is selectively attachable to one of a positive terminal and negative terminal of a traction battery cell via a transistor. The circuit has a current sensor disposed in series with an inductor. A controller operates the transistor such that electrical current from the one of the positive terminal and negative terminal is inverted within the circuit, and while an inductor charge rate is less than a predetermined charge value, inhibits charge and discharge of the traction battery cell.
