Abstract: A system and method regulate the temperature of an electrochemical battery. The system can be incorporated in a hybrid or electric motor vehicle including at least two electrical-energy-accumulating elements, each element including at least one electrochemical cell. The system increases the intensity of the value of the current flowing through the battery up to a first threshold value and includes a module for disconnecting and connecting an electrical-energy-accumulating element.

Abstract: A method for evaluating a quantity of energy at constant power of a battery includes determining a value of a capacity parameter for the battery, constructing a table of values for a parameter of voltage across terminals of the battery as a function of a value of a current parameter, for N values of a state of charge parameter, determining a value of an internal resistance parameter for the battery, providing a table of values of an open-circuit voltage parameter, estimating a value of the state of charge parameter at an initial time, and estimating a quantity of energy parameter between a final and initial states of charge using a function whose variable is the state of charge parameter and whose parameters are said value of the capacity parameter for the battery, said value of the internal resistance parameter, and said value of the open-circuit voltage parameter.
