System for recharging the battery of a motor vehicle
First Claim
1. A system for recharging a battery of a motor vehicle, including:
- a current generator including an alternator with an armature winding and a field winding, and a rectifier, the output of the generator being connected to a terminal of the battery,a switch connected to said terminal of the battery,an indicator lamp connected in series with the switch, anda voltage regulator which has first and second inputs connected to the output of the generator and to the lamp respectively, and which is activated through the switch and the lamp, the regulator includinga circuit for regulating a current supplied to the field winding of the alternator in dependence on the voltage supplied by the generator,a supply circuit for supplying the voltage regulator, andcontrol circuitry connected to the lamp for enabling the supply circuit to operate when the lamp is on and when the generator is operating;
the control circuitry including first comparator means connected to the second input of the voltage regulator, and hence to the lamp, and supplying a first enabling signal to the supply circuit when the voltage at the second input exceeds a first predetermined threshold.

Abstract
A system for recharging a battery includes a current generator, a switch operable by a key and connected to the battery, an indicator lamp connected in series with the switch, and a voltage regulator with first and second inputs connected to the output of the generator and to the lamp, respectively. The regulator includes a circuit for regulating the current supplied to the field winding of the alternator in dependence on the voltage supplied by the generator, a supply circuit for supplying the voltage regulator circuit, and control circuit for enabling the supply circuit to operate when a current is flowing in the lamp and when the generator is in operation. The control circuit includes a comparator connected to the second input of the regulator, and hence to the lamp, and adapted to supply an enabling signal to the supply circuit when the voltage at the second terminal exceeds a predetermined threshold.
