CELL VOLTAGE SENSING FOR RECHARGEABLE BATTERY PACKS
Abstract:
A battery system has positive and negative pack terminals, and positive and negative sense terminals. An electrochemical cell assembly has positive and negative cell terminals. An electrically conductive power path has a positive leg that connects the positive cell terminal to the positive pack terminal, and a negative leg that connects the negative cell terminal to the negative pack terminal. A power switch circuit is connected in the power path. An electrically conductive sense path separate from the power path has a positive leg that connects the positive cell terminal to the positive sense terminal, and a negative leg that connects to the negative sense terminal. A sense switch circuit is connected in the sense path. Other embodiments are also described and claimed.
