Abstract
624,043. Charging batteries; automatic control of current. LUCAS, Ltd., J., and LAIRD, J. A. April 17, 1947, No. 10192. [Class 38.(iv)] An excitation control circuit for a vehicle or other dynamo 1 charging a battery 3 comprises. normally closed contacts 7 in the field circuit 2 of the dynamo which contacts become vibratory under the action of winding 4 of an electromagnet 4, 5 in the charging circuit when the charging current reaches a predetermined value, thus limiting the charging current. The winding 5 is normally short-circuited by further contacts 8 of a relay 8, 9, the winding of which is energized from the dynamo or battery, so that at a predetermined state of charge the short-circuit on winding 5 is removed. This winding then assists winding 4 and causes vibratory action of contacts 7 at a lower charging rate and thus prevents over-charging. A further winding 10, carrying the charging current when contacts 8 open, may act on these contacts to maintain them open. A winding 11 responsive to the generator voltage may open the contacts 7 under excessive voltage condition, for instance if the battery becomes open-circuited. The charging circuit includes the usual cut-out 6. A lighting load 12 may be connected as shown, or directly across the battery.
