ABSTRACT:
A method for gauging battery charge in which current flowing from a battery (11) is integrated (25) and a charge counter counts charge. Voltage (Vb) across the battery is measured (16) and compared (26) with a voltage threshold (28). The counter (27) is reset to a predetermined value (29) when the measured voltage crosses the voltage threshold.
