Battery power adaptation method

Abstract

Title of the invention: Power adaptation method for a battery. The present invention relates to a power adaptation method for an electrical storage device (1) comprising a plurality of cells (6) capable of carrying an electric current and each provided with an active part (16) and an electrical connection element (18), the power adaptation method comprising a first step of determining a temperature of the electrical connection element (18) of at least one cell (6) and a second step of adjusting the power of the electrical storage device (1) as a function of the temperature determined during the first step, the first step comprising a substep of determining a temperature of the active part (16) of the cell (6),a substep of determining the current in the electrical storage device (1) and a substep of estimating the temperature of the electrical connection element using the values ​​determined in the previous substeps and a temperature model.
