Patent number: 10777852Abstract: A battery system includes a main electrochemical cell that includes a cathode and an anode, a cathode tab electrically coupled to the cathode, and an anode tab electrically coupled to the anode. A second electrochemical cell is electrically coupled to the cathode tab and the anode tab. An interrupt device, such as a bi-stable metal disc, is operably coupled to the second electrochemical cell and at least one of the cathode tab or the anode tab.
