Abstract

446,229. Charging batteries; automatic control systems. WETZER, R., Pfronten, Bavaria, Germany. Aug. 16, 1935, No. 23077. [Class 38 (iv)] The voltage of a battery is maintained within two predetermined limits by supplying current at high or low charging rates controlled by a one contact relay which closes and opens at maximum and minimum voltage respectively, the contact pressure being increased by cutting out a series resistance after contact is made. The battery b is charged from the supply terminals k through the charging resistance r, part of which. may be short circuited by contact s actuated by resistance W1 to give the high charging rate. Contact m is then open and current flows from the battery of the relay R through moving coil B and resistance W1. When the voltage rises to the predetermined maximum, contact m closes and short circuits resistance W1, the increased current through coil B increasing the pressure of the contact. Contact S also opens and resistance r is then included in the charging circuit.
