A system for estimating a parameter of a battery assembly includes a sensing device connected to a cell of the battery assembly, the battery assembly having a first battery chemistry, the sensing device including a measurement cell having a second battery chemistry that is different than the first battery chemistry. The system includes an estimator configured to acquire a set of first estimates of a first state of charge (SOC) of the battery assembly, acquire a set of second estimates of a second SOC of the sensing device, and blend the sets of estimates to generate a blended SOC relation describing the second SOC of the sensing device as a function of the first SOC of the battery assembly. The estimator is also configured to filter the set of first estimates using the blended SOC relation to generate a final estimate of the SOC of the battery assembly.
