Patent ID: 7834583

Claim:
A remotely controllable multiple battery system for reliably supplying electrical energy to a vehicle electrical system, the remotely controllable multiple battery system receiving control signals from a remote control device, the remotely controllable multiple battery system comprising: a main battery; at least one sensor operable to sense at least one operating condition of the main battery and produce at least one output based on the at least one operating condition of the main battery; at least one auxiliary battery; at least one controllable switching device coupled to the main battery and the at least one auxiliary battery, the at least one controllable switching device being responsive to at least one control signal to engage one of the main battery and the at least one auxiliary battery to solely supply electrical energy only to the vehicle electrical system such that the main battery and the at least one auxiliary battery never supply electrical energy to the vehicle electrical system simultaneously while the vehicle is in operation; and a controller in communication with the remote control device and coupled to the at least one sensor and the at least one controllable switching device, the controller operable to monitor the at least one output of the at least one sensor and provide an indication of the at least one operating condition to the remote control device, the controller further operable to receive the at least one control signal from the remote.
