Abstract: A battery system (1) has positive (PACKP) and negative (PACKN) pack terminals, and positive (SENSEP) and negative (SENSEN) sense terminals. An electrochemical cell assembly (2) has positive and negative cell terminals. An electrically conductive power path has a positive leg (9a) that connects the positive cell terminal to the positive pack terminal, and a negative leg (9b) that connects the negative cell terminal to the negative pack terminal. A power switch circuit (5) is connected in the power path. An electrically conductive sense path separate from the power path has a positive leg (4a) that connects the positive cell terminal to the positive sense terminal, and a negative leg (4b) that connects to the negative sense terminal. A sense switch circuit (6) is connected in the sense path.
