  • Method for calculating the parameters of the power battery of an electric motor vehicle
    Patent number: 6788069
    Abstract: The invention relates to a method for determining at least one operating parameter of the power battery of a vehicle having an electric traction motor. The battery parameter includes at least one of the following parameters: charging capacity, discharge power, state of overcharge or state of total discharge. The power battery's internal resistance and the intensity of the current supplied or received are determined in order to calculate the parameter(s). This internal resistance is calculated, for example, using a low voltage auxiliary battery.
