摘要
A system includes a cell voltage measurement device and a cell current measurement device configured to measure the voltage and cell current of battery cells within a battery pack. The cell voltage measurement and cell current measurement devices share one or more filter characteristics, such that the filters used for voltage and current measurements produce similar responses. The voltage and current measurements may correspond to a similar or identical period of measurement. Charge transferred by the cell or battery string during a measurement period may be measured or calculated, for example by a coulomb counter. One or more charge transfer models for a cell or battery pack may be updated using the voltage, current, and charge measurements. Contiguous measurements of current in a string of battery cells may be made, to correspond to cell measurements that cycle, via a multiplexor, through several cells within the string.
