Abstract

1,218,025. Electric control systems. PLESSEY CO. Ltd. 9 March, 1970 [19 July, 1967], No. 33279/67. Heading H2H. A storage battery 1 is supplied from a charging unit 2 which is switched off when semiconductor temperature sensing elements 4, 5 respectively inside and outside the battery 1, indicate by differences in voltage drop a change in relative temperatures to operate a control amplifier 6 which may also influence a state of charge indicator 7. The temperature difference will occur when a battery particularly a nickel-cadmium battery, is fully charged and the apparatus will provide charging pulses each time the temperature differential decreases. The charging unit 2 provides a constant changing current due to transistors 8, 9, Zener diode 11 and resistors 11, 12 and the switch 13 is a transistor which conducts when the voltage from the amplifier 6 exceeds a predetermined value.
