Abstract

A method for determining the charge drawn by an energy storage battery starting from an initial state of charge at the start of the drawing of the charge includes determining the charge drawn as a function of an exponential function with a time constant. The time constant is defined at least as a function of the energy storage battery type and of the temperature of at least one of the battery temperature and the electrolyte temperature. The method may be carried out utilizing a monitoring device or a computer program.
