A security system for a battery module includes at least one battery module having positive and negative poles and defined by a matrix comprising two or more columns and two or more lines. The matrix is such that each column defines an accumulator branch having m accumulators in series and such that each line of the matrix defines an accumulator stage. At least one charge control device is connected to the poles of the battery module. The battery module includes a plurality of resistors respectively electrically linked to the intermediate point between two accumulators of two adjacent accumulator stages and a third predefined number of connection nodes respectively connected to a set of resistors connected to the intermediate points of the accumulators of the two adjacent accumulator stages. The charge control device is connected to the set of connection nodes.
