  • System and method for determining battery state-of-health
    Patent number: 6469512
    Abstract: A system and method for accurate and in real time determination of factors relating to the state of health of a storage battery. The system measures the values of battery temperature, voltage and current flow into and out of the battery. This data is multiplexed into a computer and the battery's internal resistance (IR), polarization resistance (PR), state of charge (SOC) and its cold cranking amp (CCA) capability are computed and displayed. The presence of shorted and mismatched cells also can be determined and displayed. The state of health of the battery is related to these displayed measured values and calculated factors which are made known to the user of the battery.
