Abstract

974,492. Charging and discharging batteries. PYRENE CO. Ltd. July 31, 1961 [July 29, 1960], No. 26492/60. Heading H2H. A thermistor 4 is connected in parallel with a resistance 5 of lower ohmic value which carries the trickle-charge current of a battery 1, the arrangement being such that when the voltage of the battery 1 falls below a predetermined value the voltage across thermistor 4 increases causing it to pass a higher current which then progressively increases with the thermistor temperature, the maximum charging current being determined by a resistance 6. In a modification, Fig. 2 (not shown), the thermistor is used to control a transistor which is connected in parallel with the trickle-charge resistance and carries the increased charging current consequent upon a fall in the battery voltage, this current being limited by resistors in series with the transistor. The transistor may be replaced by a silicon-controlled rectifier and the thermistor by a Zener diode. The Provisional Specification states that further transistors may be connected in parallel with th e first transistor and arranged to conduct when this transistor passes current.
