| Zusammenfassung: | A battery monitor system (10) for determining a cell voltage (VC) between a low side contact (14) and a high side contact (16) of a cell (18) in situ as one of a plurality of cells connected in series to form a battery (20). The system (10) uses an arrangement of switches (30) and capacitors to shift relatively high absolute voltages of a battery (20) stack to a relative low voltage level so lower voltage electronics can be used to monitor cell voltages. The system (10) may be configured to provide a single ended measurement or a differential measurement indicative of a cell voltage (VC). The differential measurement may be advantageous to correct or offset signal noise caused by electromagnetic interference (EMI). |
