Electrical power supply equipment for motor vehicles
First Claim
1. Electrical power supply equipment for a motor vehicle having a main electrical system and an auxiliary electrical system for supplying auxiliary consumer equipment, the equipment comprising a main battery, an auxiliary battery, and an electrical generator adapted to be driven by the engine of the motor vehicle, wherein the improvements comprise in combination:
- a first two-position switch adapted to connect the generator selectively to the main battery and to the auxiliary battery;
a supply device for connection to an electrical mains supply;
a first line and a second line connecting said supply device to the main battery and to the auxiliary battery respectively;
a third and a fourth line connected to said supply device;
a second two-position switch having a first position which it occupies when the supply device is connected to a mains supply and in which it connects the main electrical system of the motor vehicle to the supply device through said third line, and having a second position in which it connects the main electrical system of the motor vehicle to the said generator;
a third two-position switch, having a first position which it occupies whilst the motor vehicle is stationary and in which it connects the auxiliary electrical system of the motor vehicle to the supply device through said fourth line, and having a second position in which it connects the auxiliary electrical system of the motor vehicle to the said generator;
and said supply device is adapted to connect the first line to the third line and the second line to the fourth line when the supply device is disconnected from the mains supply.

Abstract
Electrical power supply equipment for motor vehicles has a main electrical system and an auxiliary electrical system, a main battery, an auxiliary battery and an electrical generator, driven by the vehicle engine, which can be connected selectively to either battery.
A supply device can be connected to an electrical mains supply for recharging the batteries while the main electrical system is connected to the supply device. When the vehicle is running the main and auxiliary electrical systems are connected to the generator, while when the vehicle is stationary the auxiliary system is connected to the supply device which, when disconnected from the mains supply, ensures connection of both systems to the batteries.
