Abstract

The DC60 (13/11/41) trunk-mounted backup battery charger is a convenient system for charging golf cart batteries or other battery-powered electrical devices. Furthermore, this backup battery charger allows you to charge batteries even during normal vehicle operation and is conveniently stored in the trunk. The trunk-mounted backup battery charger provides a convenient way to charge golf cart batteries or other battery-powered electrical devices. Additionally, it allows you to charge batteries during normal vehicle operation and is conveniently stored in the trunk.

Claims (1)

1. A backup battery charger in the trunk compartment from the car's electrical system. This battery charger is connected between the car's alternator and the backup battery. It contains a current regulator to control the charging current to suit the size of the battery. If the voltage of the battery being charged is the same as that of the car battery, a resistor of 0.2 - 0.5 ohms is sufficient to act as a current regulator. If the two batteries have different voltages, an integrated current regulator, which is commercially available, must be used. Two relays (11,12) have normally open contacts to open and close the battery charging circuit, which operate when there is current from the car's ignition switch and do not operate when there is no current from the ignition switch. It is designed so that the regulator (10) is connected between relay (11) and relay (12).
