Multiple battery management system, auxiliary battery attachment system, and network controlled multiple battery system
First Claim
1. A vehicle multiple battery system comprising:
- An accessory battery having an accessory positive output and an accessory negative output;
an at least one starter battery having a starter positive output and a starter negative output;
a controller coupled to an at least one sensor, the controller sensing the condition of the accessory and starter batteries and switching an at least one switching device to one of an at least two switching positions;
wherein the switching device has at least two operating positions, the at least two operating positions selectively engaging said accessory battery and said at least one starter battery such that;
in a first operating position of said at least two operating positions the common positive terminal is coupled to the accessory positive output and is further coupled to the at least one starter battery positive output through a one-way charging circuit between and preceding the at least one starter battery such that in the first operating position, the one-way charging circuit permits electrical energy from the electrical system to flow into both the accessory battery and the at least one starter battery, but prevents electrical energy from flowing out of the at least one starter battery and;
a second operating position of said at least two operating positions which couples the common positive terminal to the starter positive such that the common positive terminal is coupled at a point beyond the one-way charging circuit to the starter battery positive.

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.

15. A vehicle multiple battery management system comprising:
-
a common positive and common negative terminal; an at least one accessory battery having an accessory positive output and an accessory negative output; at least one starter battery having a starter positive output and starter negative output; and a battery management system comprising an at least one controller, an at least one switching device, an at least one recharging selection mechanism, and an at least one sensor, wherein the battery management system through the at least one switching device has at least two operating positions that selectively couples the common positive terminal with at least one of the accessory outputs or at least one starter battery positive outputs, wherein in a first operating position of the at least two operating positions the battery management system selectively couples through the at least one switching device the common positive terminal to the accessory positive output of the at least one accessory battery and in a second of the at least two operating positions the battery management system selectively couples the common positive terminal through the at least one switching device to the starter positive output of the at least one starter battery; and the battery management system also selectively couples the at least one recharging selection mechanism to the at least one accessory battery or the at least one starter battery by coupling, through the at least one one-way charging circuit that proceeds the recharging selection mechanism, the respective at least one accessory battery or the at least one starter battery output to the common terminal. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A vehicle multiple battery system comprising:
-
an accessory battery having an accessory positive output and an accessory negative output; a starter battery having a starter positive output and a starter negative output; a controller coupled to an at least one sensor, the controller sensing the condition of the accessory and starter batteries and switching an at least one switching device to one of an at least two operating positions, the at least two operating positions selectively engaging said accessory battery and said starter battery and comprising; a first operating position of said at least two operating positions wherein the common positive terminal is coupled to the accessory positive output and is further coupled to the at least one starter battery positive output through a one-way charging circuit between and preceding the at least one starter battery and; a second operating position of said at least two operating positions which couples the common positive terminal to the starter positive such that the common positive terminal is coupled at a point beyond the one-way charging circuit to the starter battery positive, wherein upon sensing a startup sequence, the controller places the at least one switching device in the second operating position which puts the starter battery alone in series with the electrical system and prevents electrical energy in the starter battery from flowing to the accessory battery.
