US Patent 12062815 Battery system

Circuit module for coupling a plurality of battery cell units. The circuit module includes a first set of terminals having a positive terminal and a negative terminal for coupling to a first battery cell unit, and a second set of terminals having a positive terminal and a negative terminal for coupling to a second battery cell unit. The positive terminal of the first set of terminals is coupled to the negative terminal of the second set of terminals either directly or via one or more passive components, and the negative terminal of the first set of terminals and the positive terminal of the second set of terminals each is coupled to a switching assembly. The switching assembly is operatively configured to selectively connect or bypass each one of the battery cell units. The invention is also directed to a battery system including the circuit module and a plurality of battery cell units.
