Patent GB-596679-A (GB)
Title: Improvements in or relating to systems for charging electric accumulators supplying an intermittent load
IPC: H04M19/00
Filed: 1945-05-18
Abstract: 596,679. Charging batteries. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). May 18, 1945, No. 12600. [Class 38 (iv)] A battery 7, Fig. 1, supplying an intermittent load is charged from an A.C. source 1 through a transformer, rectifier 6 and reactor 3, the last having a D.C. control winding 4 which varies the impedance of the reactor in accordance with the current demands of the battery and load, and a further control winding 5 which assists winding 4 when the load is de-energized and so increases the charging voltage. Under load conditions, winding 5 is short-circuited by a switch 8 which automatically closes upon flow of load current. Instead of the winding 5, a resistance may shunt winding 4, the switch 8 removing a short circuit on part of this resistance when the load is de-energized. In another arrangement, Fig. 3, the winding 5 is normally energized, over an amplifier 13, in dependence upon the battery volts, the switch 8 being open when load current flows. Switch 8 closes when the load is de-energized, thereby applying additional voltage input to the amplifier through transformer 11 and rectifier 12 and so increasing thet excitation of winding 5,to raise the charging volts. In another form, winding 5 opposes winding 4 and is connected directly across the battery when the latter is supplying a load. Upon disconnection of the load, a relay coil and a resistance are placed in series with winding 5. The charging volts thus increase, but at a certain voltage the relay picks up and cuts out some of the series resistance, thereby reducing the charging volts.
