摘要： A method for determining the state of charge (SOC) of a battery by measuring its open circuit voltage (OCV) either with the battery in a fully rested state of chemical and electrical equilibrium or an active state during a period in which the battery settles after charge or discharge is stopped. A first type algorithm is developed to correlate the OCV in a fully rested condition (OCVREST) to the state of charge at which that measurement is taken. A second type algorithm is developed that predicts a final settling OCV of a battery (OCVPRED), based on the set of parameters of OCV, rate of change of OCV, and battery case temperature, acquired during the settling period of a battery not at rest. To determine the SOC of a battery being tested that is in the fully settled state the measured OCVREST is applied to the first type algorithm. To determine the SOC of a battery that has not fully settled, the data of the OCV, rate of change of OCV and battery temperature is applied to a second type algorithm to determine OCVPRED and the OCVPRED value is used in the first type algorithm to determine SOC.

摘要： A method of predicting by non-invasive testing the available energy of a battery at any state of charge by acquiring data of the parameters of internal resistance (IR), open circuit voltage (OCV) and temperature (T), the points of voltage and current of the slope on a positive current ramp of Vup and Iup at the transition from charge to overcharge and on a negative current ramp of Vdn and Idn at the transition from overcharge to charge for a plurality of batteries. Next an algorithm in the form of a linear equation is developed using this data. The available energy of a battery under test is predicted by acquiring from it the numerical data values of these parameters and applying them to the algorithm.

摘要： Current flowing into and out of a battery installed in a vehicle (V) with the required cable between one of the battery terminals and a reference point on the vehicle is determined by measuring the voltage across the cable and computing the current from the digital value of the measured current. The resistance value of the cable can be known in which case the current is computed using Ohms law and a differential current sensor can be used to respond to the voltage measured across the cable to accommodate for different ranges of current. In an embodiment where the cable resistance is unknown, a reference current source produces a known voltage that is used to set the input value to an amplifier of fixed gain for the voltage measured across the cable by controlling the output of a potentiometer so that the amplifier output voltage can be set to match the reference current generator output voltage, thereby establishing the voltage output of the amplifier as a measurement of the current flow in the cable.
