Multiple battery switching method and apparatus
First Claim
1. A vehicle multiple battery system operating a vehicle electrical system connected between a system positive and a system negative terminal, the system comprising:
- a main battery having a main positive output coupled to an at least one switching device having at least two operating positions and a main negative output;
at least one switching device and an at least one standby negative output coupled to the vehicle electrical system negative terminal; and
a main electrical circuit comprising a coupling of the system positive terminal with the at least one switching device, the at least one switching device having at least two operating positions to selectively and exclusively couple either the main or the at least one standby battery positive output to the system positive terminal to start and operate the vehicle electrical system;
wherein in a first operating position of an at least two operating positions electrical power is provided exclusively by the main battery at startup of the vehicle electrical system and the main battery is recharged by the vehicle electrical system and an at least one one-way charging circuit receives electrical power from the vehicle electrical system, the at least one one-way charging circuit simultaneously recharging the at least one standby battery without permitting the at least one standby battery to be engaged to start the vehicle electrical system, operate the vehicle electrical system, or electrically couple to the main battery; and
wherein in a second operating position of the at least two operating positions the main battery is electrically isolated by the one-way charging circuit from the at least one standby battery and the at least one standby battery exclusively provides electrical power to the vehicle electrical system at startup; and
a controller coupled to the main electrical circuit and the one-way charging circuit, the controller switching said at least one switching device based on input from an at least one sensor to selectively and exclusively provide power in each of the switch positions as enumerated, such that the main battery and the at least one standby battery never supply electrical energy to the vehicle electrical system simultaneously.

Abstract
The instant invention is directed to a multiple battery system and network controlled multiple battery system. A main battery having a main positive output and a main negative output is also provided, together with an at least one auxiliary battery having an at least one auxiliary positive output and an at least one auxiliary negative output. A main electrical circuit having an at least one switching device is provided with at least two operating positions. The two operating positions selectively couple the main and at least one auxiliary battery to the common positive terminal. In the first of the at least two operating positions electrical charge is provided to both the main battery and the at least one auxiliary battery. A controller is also provided and coupled to the main electrical circuit and switches the at least one switching device based on input from an at least one sensor.
