Abstract

The charging system has a switch out device, and a battery voltage measuring circuit. It also has a device which memorises each measured voltage until the following voltage measurement. It has a comparator circuit which compares the instantaneous battery voltage which that previously measured. measured. The charging system has also a pulse generator which provides a train of first pulses to control the periodic output of the memory device contents. The pulse generator also generates a second group of pulses each of which respectively appear between two successive first pulses. The pulses are generated with respect to the battery voltage during charging. The second pulses are designed to interrogate the comparison circuit. They authorize actuation of the switch out device when equality exists between the comparator circuit, voltage in memory and battery voltage.
