Title: SYSTEM AND CORRESPONDING METHOD FOR MANAGING A BATTERY COMPRISING A PLURALITY OF BATTERY CELLS
Abstract:
The invention relates to a system for managing a battery (1) comprising a plurality of battery cells (2), said system comprising: a checking circuit connected in parallel with each cell and an electrical connection (102) between a first checking circuit (104n) of a first cell and a second checking circuit (104n-1) of a second cell, each circuit being capable of emitting a signal that is representative of physical parameters of the cell with which is it connected; a control unit (106) of the system; a power bus (108) providing an electrical connection between said battery cells; each circuit being configured to output said representative signal towards the control unit via the power bus, only after receiving a synchronisation signal received on the electrical connection thereof.
