<p>1,112,014. Over-discharge prevention. SONOTONE CORPORATION. 15 Oct., 1965 [19 Oct., 1964], No. 43836/65. Heading H2H. An arrangement for preventing polarity reversal on discharge of one or more of the cells of a rechargeable battery comprises selecting a cell during manufacture having a lower than average capacity and connecting this to a switching device to break the discharging circuit at a determined voltage. The device may be a transistor 50<SP>1</SP> the baseemitter of which is connected selected cell and which outs off at voltage. The cut-off point may by a diode 84<SP>1</SP>. A switch 22-1, 22 the transistor as a diode for charg Alternatively a separate diode (e. not shown), may shunt the transistor. The transistor may be replaced by a relay. In an alternative arrangement, a discharge resistor discharge. The battery is recharged from a shunts the selected cell to ensure premature constant current rectifier unit 76.</p> |
