Telematics-based system for protecting against vehicle battery drain
First Claim
1. A method for preventing discharge of a vehicle battery of a telematics-equipped vehicle, the method comprising:
- monitoring the charge of the vehicle battery;
first determining, by a telematics unit while a vehicle engine is off, that charge of the vehicle battery has reached a first low battery charge threshold;
first disabling, by the telematics unit in response to the first determining, at least a first load draining the vehicle battery;
second determining, by the telematics unit while the vehicle engine is off, after the first determining, that the charge of the vehicle battery has reached a second low battery charge threshold; and
second disabling, by the telematics unit in response to the second determining, at least a second load draining the vehicle battery wherein the first load is of lower priority than the second load.

Abstract
Systems and methods are provided for detecting low vehicle battery charge and responding appropriately to prevent complete vehicle battery drainage. One method includes: monitoring the charge of the vehicle battery; determining, by a telematics unit, that the charge of the vehicle battery has reached a low battery charge threshold while the vehicle engine is off; and providing, by the telematics unit, a notification to a telematics subscriber that the vehicle battery has low charge. Another method includes: monitoring the charge of the vehicle battery; determining, by a telematics unit, that the charge of the vehicle battery has reached a low battery charge threshold while the vehicle engine is off; and in response to determining that the low battery charge threshold has been reached, disabling at least one load draining the vehicle battery.

5. A non-transitory computer-readable medium having processor-executable instructions stored thereon for preventing discharge of a vehicle battery of a telematics-equipped vehicle, the processor-executable instructions, when executed by a processor, facilitate:
- monitoring the charge of the vehicle battery;
first determining, while a vehicle engine is off, that charge of the vehicle battery has reached a first low battery charge threshold; first disabling, in response to the first determining, at least a first load draining the vehicle battery; second determining, while the vehicle engine is off, after the first determining, that the charge of the vehicle battery has reached a second low batter,/charge threshold; and second disabling, in response to the second determining, at least a second load draining the vehicle batter; wherein the first load is of lower priority than the second load. - View Dependent Claims (6, 7, 8, 11, 12)
