ADJUSTMENT OF CONTROL STRATEGY BASED ON TEMPERATURE
First Claim
1. In a vehicle having a battery that selectively supplies electric power for starting an engine of the vehicle and that selectively supplies electric power to a plurality of electric loads of the vehicle, a method of protecting the battery comprising:
- (a) obtaining a temperature;
(b) determining a state of charge (SOC) of the battery;
(c) determining a first threshold based on the obtained temperature;
(d) determining a second threshold based on the obtained temperature, said second threshold being different than the first threshold;
(e) taking a first remedial action if the SOC is below the first determined threshold; and
(f) taking a second remedial action if the SOC is below the second determined threshold, said second remedial action being different from the first remedial action.

Abstract
A method of protecting a battery is provided in a vehicle having a battery that selectively supplies electric power for starting an engine of the vehicle and that selectively supplies electric power to a plurality of electric loads of the vehicle. The method includes: obtaining a temperature; determining a state of charge (SOC) of the battery; determining a first threshold based on the obtained temperature; determining a second threshold based on the obtained temperature, the second threshold being different than the first threshold; taking a first remedial action if the SOC is below the first determined threshold; and taking a second remedial action if the SOC is below the second determined threshold, the second remedial action being different from the first remedial action.

10. In a vehicle having a battery that selectively supplies electric power for starting an engine of the vehicle and that selectively supplies electric power to a plurality of electric loads of the vehicle, a battery protection system comprising:
-
temperature sensing means for obtaining a temperature; battery sensing means for determining a state of charge (SOC) of the battery; threshold determining means for determining a first threshold based on the temperature obtained by the temperature sensing means and a second threshold based on the temperature obtained by the temperature sensing means, said second threshold being different than the first threshold; and remedial action means for taking a first remedial action if the SOC is below the first determined threshold and a second remedial action if the SOC is below the second determined threshold, said second remedial action being different from the first remedial action. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. In a vehicle having a battery that selectively supplies electric power for starting an engine of the vehicle and that selectively supplies electric power to a plurality of electric loads of the vehicle, a battery protection system comprising:
-
a first sensor that measures at least one of a temperature of the battery, a temperature of the vehicle'"'"'s engine and an ambient temperature; a second sensor that detects a state of charge (SOC) of the battery; and a controller that;
(i) determines a plurality of different thresholds based upon the measurement from the first sensor;
(ii) compares the SOC detected by the second sensor to the plurality of thresholds; and
(iii) selectively triggers a plurality or different remedial actions in response to comparing the detected SOC to the plurality of different thresholds. - View Dependent Claims (20)
