PROCEDURES AND PREPARATION FOR THE MONITORING OF AN ELECTROCHEMIC ENERGY SPECIFIC CELL AND VEHICLE

摘要

The invention concerns a procedure for monitoring an electrochemical energy storage cell, in particular a lithium ion cell, which has electrodes and at least one derivative element electrically connected to one of the electrodes, with the following steps: capture an impedance of the energy storage cell; Determine a first temperature value which characterises a temperature prevailing in the field of electrodes, based on the imaging part or phase of impedance and/or determine a second temperature value which characterises a temperature prevailing in the derivative element,based on the actual part or amount of impedance. The invention also concerns an appropriate device and a vehicle, in particular a vehicle with such a device.
