Abstract
1286781 Battery charging systems Mc- CULLOCH CORP 12 Jan 1971 [30 Jan 1970] 1337/71 Heading H2H Apparatus for rapidly charging a battery comprises means whereby the battery is alternately charged and discharged, the operation being controlled by two signals, one of which is responsive to a function of the battery and the other of which is dependent on the voltage of the charging supply, the second signal being arranged to oppose the first signal. A battery 1 is charged from an A.C. source 9 by way of a transformer 2 and a pair of thyristors 3, 4 so that the battery receives charging current in a series of full wave rectified unsmoothed pulses. As the battery charge increases the battery terminal voltage is integrated by means of a capacitor 18 and resistors 14, 15, 16, 17. During the times that charging pulses are being applied to the battery 1, either a diode 22 or 23 is conducting so that a signal is developed across resistor 17 which is negative to earth. Thus whilst charging pulses are being applied to the battery, firing of a thyristor 19 is inhibited thereby preventing a transistor 10 forming the battery discharge patch from becoming conductive whilst either thyristor 3, or 4 is conducting. As the capacitor 18 increases its charge it reaches a value sufficient to gate the thyristor 19 on, which will occur when the charging pulses are at zero value and the inhibiting signal across resistor 17 has disappeared. Conduction of thyristor 19 then causes conduction of transistor 10 to form a low impedance path for discharge of the battery for depolarizing purposes. The capacitor 18 also discharges to reset itself. As the charging of the battery increases with alternate charge and discharge periods, the discharge transistor 10 is rendered conductive more and more frequently. As the battery charge increases the increasing battery voltage is sensed by a voltage divider including a Zener diode 29 and potentiometer 31 and eventually a thyristor 34 is gated on whereby the gates of thyristors 3, 4 are grounded to inhibit firing of the thyristors to terminate the rapid charging of the battery 1. A trickle charge is maintained by diode 26 and lamp 28. Termination of the rapid is made responsive to the quiescent terminal voltage of the battery 1 by arranging that the inhibiting negative signal developed by diodes 22, 23 renders a transistor 40 conductive-and hence inhibits conduction of thyristor 34-whenever charging pulses are being applied to the battery 1.
