Abstract:
1. A storage battery comprising a plurality of cells arranged in at least three branches, each branch having at least n cells connected in series, wherein n≧2 and wherein the cells with index i of each branch being connected in parallel and forming a stage of index i, with i being between 1 and n; the battery further comprising fusible electrical connections, each fusible electrical connection connecting two cells of a given stage in parallel and two cells of an adjacent stage in parallel, wherein the cutoff threshold of the fusible electrical connections are designed to conduct current when one of said cells it connects forms an open circuit; the battery further comprising a balancing circuit, for balancing the charge of the cells, said balancing circuit being connected to a terminal of each stage by way of at least two different nodes within each stage; wherein the number of cells, n, in each branch is high enough so that an overvoltage caused by a short circuit in a cell does not destroy the other cells in the respective branch.
