The method involves generating a thermal flux at each point of a space by an electrochemical model based on exothermic and endothermic chemical reactions, where the thermal flux is integrated at each time step according to thermal and geometric characteris...

To reduce calculation errors of remaining battery power so as to take into account capacity diminutions due to cycle degradation and temperature, a remaining power calculation means specifies a temperature correction value for calculation of remaining batt...

The subject of the present invention is a method for controlling the discharge of a battery comprising modules constituted of at least one electrochemical generator which comprises the following steps: (a) at an instant t one measures a voltage Vz(t) of ea...

The method involves estimating the open-circuit voltage (UR), internal resistance (RI) and internal voltage drop (UK) caused by density variations in the battery acid. A model is initialized to estimate the capacity with the estimated values. The model is ...

The characteristic of the critical charging voltage as a function of the charging current is determined for different temperatures, and linearized by a function of the form A(I)xT+B(I). The values A and B are stored in a battery management system. In opera...
