  • Method for detecting a motor vehicle battery failure
    Patent number: 6472875
    Abstract: A process for the detection of a defect of an automotive vehicle battery includes analyzing the time dependence of the discharge voltage across the terminals of the battery. This process has the steps of measuring at least two successive values of the discharge voltage of the battery, during the phase of cranking the engine of the automotive vehicle, for at least two consecutive top dead center points, taking a difference of the measured voltage values, and deducing therefrom whether the battery is charged or defective. The process is built into an electronic computer carried on board the automotive vehicle.
