First Claim
Patent Images
1. A self-powered battery jump method in a vehicle having a first battery and a second battery, the method comprising:
- connecting the first battery only to an alternator of the vehicle;
connecting the second battery to the alternator and to operating loads of the vehicle;
connecting a switch between terminals of the first battery and terminals of the second battery, and placing the switch in a first position in which the terminals of the first battery are not electrically connected to the terminals of the second battery; and
moving the switch to a second position to connect the first battery terminals to the second battery terminals when the second battery is no longer sufficiently energized to operate the vehicle loads.

Abstract
The self-powered battery jump method uses a vehicle'"'"'s alternator to charge main and spare batteries during vehicle operation. If the main battery loses its power, the spare battery supplies power to the main battery and to the vehicle'"'"'s engine in order to start the vehicle whenever it is needed without any external electricity. Manual, semi-automated, and automated jump modes are provided.

6. A self-powered battery jump system for a vehicle, comprising:
-
a main battery disposed in the vehicle, the main battery being adapted for connection to a charging system of the vehicle and to an electrical load of the vehicle, the electrical load including an engine of the vehicle; a spare battery disposed in the vehicle, the spare battery, when not jumpered, being connected solely to the charging system of the vehicle, the spare battery accepting electrical charge from the charging system when a charge level of the spare battery is low; and means for removably electrically jumpering the spare battery to the main battery when the main battery lacks sufficient charge to cause the engine to start. - View Dependent Claims (7, 8, 9)
