Abstract
A method for determining respective thermal characteristics of a plurality of electrochemical cell assemblies in an energy storage system includes (1) sensing open circuit voltage of each electrochemical cell assembly of the plurality of electrochemical cell assemblies over a measurement time period, (2) controlling temperature control equipment of the energy storage system to change a temperature setpoint of a heat transfer fluid during the measurement time period, (3) generating a respective voltage profile for each electrochemical cell assembly, (4) determining a respective electrical time constant for each electrochemical cell assembly from the respective voltage profile for the electrochemical cell assembly, and (5) determining a respective thermal characteristic for each electrochemical cell assembly at least partially based on the respective electrical time constant for the electrochemical cell assembly.
