Abstract

L'invention concerne un dispositif (30) de mesure de l'impédance d'un élément (12) de stockage d'énergie d'une batterie électrique, ledit élément comprenant des première et deuxième bornes (14, 16) . Le dispositif comprend une première résistance (RO) reliant la première borne à un premier noeud (A) et un premier circuit (18) monté entre le premier noeud et la deuxième borne et adapté à solliciter l'élément (12) pour la fourniture d'un courant à travers la première résistance, le premier circuit comprenant un deuxième noeud de réception d'un premier potentiel d'alimentation (VCC) et un troisième noeud pour la réception d'un deuxième potentiel d'alimentation (GND) inférieur strictement au premier potentiel, le deuxième noeud étant relié au premier noeud.
