A METHOD AND SYSTEM FOR MONITORING THE STATUS OF BATTERY CELLS
The invention relates to a method for monitoring the status of a plurality of connected battery cells (C1-C10) in a battery pack (7a), said method comprising: arranging said battery cells (C1-C10) in at least two groups (G1-G6) of cells; connecting said groups (G1-G6) of cells to a sensor unit (7b); and providing a measurement of at least one parameter indicative of the state of operation of said battery pack (7a) by means of said sensor unit (7b). The method according to the invention further comprises: arranging said groups (G1-G6) of cells (C1-C10) in a manner so that at least two of said groups (G1-G6) comprise two or more cells and at least two of said groups (G1-G6) overlap so that a cell forms part of said overlapping groups; and connecting said sensor unit (7b) to said groups (G1-G6); and wherein the number of groups (G1-G6) is less than the number of cells (C1- C10).
