Abstract

The battery charger, has a constant current source (2) with three levels of output (11, 12, 13) fo charging a battery (1). It comprises a switching circuit with three relays (3, 4, 5) interposed between the battery (1) and the current source (2). Each relay (3, 4, 5) is energised by a binary circuit (6, 7, 8) which is operated by pulses from a comparator (9). This comparator (9) detects a difference between the reference voltage of a potentiometer (10) and the voltage across the terminals of the battery (1). The charger is initially excited by switching the first binary circuit (6) which in turn energises the first relay (3) to provide intensive charging of the battery (1).
