<p>An apparatus for monitoring the state of charge of a battery having a shunt resistor (14) connected in series with a battery (10) and an integrating circuit (30) connected across the terminals of the shunt resistor (14) is provided. The integrating circuit (30) includes a Memoriode (36) having a large capacitance and the capability to store charge for long periods of time, so that the integration can be performed along the same curve even if power to the integrating circuit is interrupted. <IMAGE></p> |
