Abstract

A bipolar battery system includes N battery cells. Each of the N battery cells comprises M cores each comprising a first current collector, cathode active material, a separator, anode active material, and a second current collector, where M is an integer greater than one. The M cores are connected in parallel by connecting the first current collectors of the M cores in each of the N battery cells together and by connecting the second current collectors of the M cores in each of the N battery cells together. N−1 clad plates are arranged between adjacent ones of the N battery cells and the N battery cells are connected in series by the N−1 clad plates. A voltage sensing system connects to the N−1 tabs, a first terminal, and a second terminal and is configured to determine N voltages across the N battery cells, respectively.
