ABSTRACT:
To prevent over charging of a battery the battery voltage is detected during charging and when a decrease in voltage, which occurs just after full charge, is detected the charger is switched off. The battery voltage may be monitored by a dual slope integrator 30 and a central processor 10 indicates the status of the battery on a display 50. During discharge the voltage drop across a resistor R connected between the battery and load is monitored by integrators 30, 40 and processor 10.
