A method of controlling a multiple battery system in a vehicle electrical system is provided. The method steps include polling an at least one sensor in the multiple battery system monitoring the multiple battery system for an at least one reading and detecting an abnormal reading from said at least one sensor. And then communicating the results of said detection step to an operator or a Network Operations Center switching, upon a command from the operator, the Network Operations Center or a controller switching an at least one switch from a first of an at least two operating positions engaging a main battery to a second of an at least two operating positions engaging an at least one auxiliary battery. The system then confirms the operation of the vehicle electrical system and engages either the main battery or the auxiliary battery, but not both, to operate the vehicle electrical system.

What is claimed is: 1. A method for controlling a multiple battery system in a vehicle, the multiple battery system including a main battery, at least one auxiliary battery, a controller, at least one controllable switching device, and at least one sensor to sense at least one operating condition of the main battery and the at least one auxiliary battery, the multiple battery system supplying electrical energy to an electrical system of the vehicle, the method comprising: polling, by the controller, the at least one sensor for at least one reading associated with at least one operating condition of the main battery; determining, by the controller, whether the at least one operating condition of the main battery is abnormal based upon the at least one reading; in the event that the at least one reading indicates at least one abnormal operating condition of the main battery, communicating, by the controller, information relating to the at least one abnormal operating condition to a remotely located control device; receiving, by the controller, a command from the remotely located control device to switch from the main battery to the at least one auxiliary battery such that the electrical energy is supplied to the electrical system solely from the at least one auxiliary battery; communicating, by the controller, a control signal to the at least one controllable switching device instructing the at least one controllable switching device to switch from a first position electrically connecting the main battery to the electrical system to a second position electrically connecting the at least one auxiliary battery to the electrical system and isolating the main battery from the electrical system such that the main battery and the at least one auxiliary battery never supply electrical energy to the electrical system simultaneously; and switching, by the controllable switching device, from the first position to the second position responsive to the control signal. 2. The method of claim 1, further comprising: initiating, by the controller, an energy conservation procedure to reduce electrical loading on the at least one auxiliary battery. 3. The method of claim 2, further comprising: monitoring, by the controller, a supply of electrical energy to the electrical system from the multiple battery system. 4. The method of claim 2, wherein the electrical system includes battery charging functionality, the method further comprising: monitoring, by the controller, a supply of charging current supplied to the multiple battery system from the electrical system. 5. The method of claim 1, further comprising, confirming, by the controller, normal operation of the electrical system subsequent to switching to the at least one auxiliary battery to supply electrical energy to the electrical system. 6. The method of claim 5, further comprising: subsequent to confirming normal operation of the electrical system with electrical energy supplied by the at least one auxiliary battery, instructing, by the controller, the at least one controllable switching device to switch back to the first position and thereby engage the main battery to supply electrical energy to the electrical system; reporting, by controller, an electrical fault condition to the remotely located control device in the event that the main battery is still in an abnormal operating condition; and continuing, by the controller, to operate the electrical system from the at least one auxiliary battery. 7. The method of claim 1, further comprising: detecting, by the controller, a cycling trigger; responsive to detecting of the cycling trigger, instructing, by the controller, the at least one switching device to switch to the second position and thereby engage the at least one auxiliary battery to supply electrical energy to the electrical system; monitoring, by the controller, the at least one sensor for at least a second reading associated with at least one operating condition of the at least one auxiliary battery; determining, by the controller, whether the at least operating condition of the at least one auxiliary battery is abnormal based upon the at least a second reading; and instructing, by the controller, the at least one switching device to switch back to the first position to thereby engage the main battery to supply electrical energy to the electrical system after a period of time. 8. The method of claim 7, further comprising: detecting, by the controller, the at least one operating condition of the main battery after the at least one switching device switches back to the first position; and instructing, by the controller, the at least one switching device to switch to the second operating position in the event that the controller again detects an abnormal operating condition for the main battery; and alerting, by the controller, the remotely located control device of an electrical fault condition in the main battery. 9. The method of claim 1, wherein the remotely located control device is at least one of a network operations center and a handheld wireless remote control device.
