| 20090248334 | METHOD FOR ESTIMATING THE CHARGE OF A MOTOR VEHICLE BATTERY - In a method for estimating the charge of a motor vehicle battery, at least one sensor measures terminal voltage, current circulating in the battery, and temperature, such that: current variations are measured at predetermined time intervals; a modeled voltage is determined according to current and temperature; the modeled voltage includes components corresponding to charge polarization; estimated and measured voltage are compared to determine voltage error; theoretical model is adapted according to battery operating phase and determined voltage error. Operating phases of the battery on charge and discharge correspond on each occasion to operation substates including 100% saturated, close to 100% saturated, normal, close to 0% charged and 0% charged and in that, for the substates, adaptation is made for theoretical computation of battery charge state and/or computation of the component corresponding to polarization, the estimate of the state of charge of the battery being determined using the adapted theoretical model. | 10-01-2009 |
