Abstract

L'invention concerne un système de gestion de batterie, qui comporte une unité de gestion de batterie (BMU) et un dispositif intégré de détection et de commutation (SSD) servant à mesurer précisément l'état de charge d'une batterie rechargeable et à assurer une protection de charge de la batterie rechargeable. Le système comporte une charge, un dispositif intégré de détection et d'alimentation comprenant un dispositif d'alimentation et un dispositif de détection ; le dispositif intégré de détection et d'alimentation est connecté entre la batterie rechargeable et la charge ; le dispositif de détection fournit un courant miroir proportionnel au courant du dispositif d'alimentation ; un premier circuit mesure le courant de la batterie rechargeable à l'aide du courant miroir, et un deuxième circuit mesure la charge de la batterie rechargeable à l'aide du courant miroir.
