초록

A method of determining the available energy of a battery provides for measuring first and second open circuit voltage of the battery with a change of energy level occurring therebetween. The two open circuit voltages are correlated to a state of charge level and the measured amount of change of energy is divided by the change of the state of charge.

We claim: 1. A method of determining the available energy of a battery comprising: measuring a first open circuit voltage of said battery to correlate to and determine a first state of charge; changing a level of energy available in said battery by a measured amount; measuring a second open circuit voltage of said battery after changing the level of energy to determine a second state of charge; and dividing the measured amount of energy change in said battery by the calculated change in the state of charge from the first state of charge to the second state of charge to determine the available energy capacity of said battery; wherein the step of changing the level of energy includes a discharge event, and the discharge event occurs at a current having a generally unvarying rate. 2. The method as defined in claim 1, further including the step of: resting said battery for a duration of time before each step of measuring said first open circuit voltage and said second open circuit voltage to obtain a diffusion equilibrium state in said battery. 3. The method as defined in claim 2, wherein the step of resting the battery further includes the duration of time comprising a first duration of time to rest the battery before conducting the step of measuring the first open circuit voltage and a second duration of time to rest the battery before conducting the second open circuit voltage, said first duration of time being about the same as said second duration of time. 4. The method as defined in claim 2, further including the step of: charging the battery, wherein the step of charging the battery occurs before the step of resting the battery, and the step of resting the battery occurs before the step of measuring said first open circuit voltage of the battery. 5. The method as defined in claim 4, wherein the step of charging the battery further includes the battery being charged to a 100% state of charge. 6. The method as defined in claim 1, wherein the duration of time is greater than 4 hours. 7. A method of determining the available energy of a battery comprising: measuring a first open circuit voltage of said battery to correlate to and determine a first state of charge; changing a level of energy available in said battery by a measured amount; measuring a second open circuit voltage of said battery after changing the level of energy to determine a second state of charge; and dividing the measured amount of energy change in said battery by the calculated change in the state of charge from the first state of charge to the second state of charge to determine the available energy capacity of said battery wherein the step of changing the level of energy comprises a charging event, and the charging event uses an overvoltage to charge the battery until a battery charge current attains a predetermined low current value being at a generally unvarying rate, said predetermined low current value being one of: (i) substantially three amps, and (ii) greater than zero amps and less than three amps. 8. The method as defined in claim 7, wherein said overvoltage is less than a gassing threshold of the battery. 9. A method of calculating a composite value for the available energy of a battery, comprising: determining a first value for the available energy of the battery using a first methodology; determining a second value for the available energy of the battery using a second methodology different from the first methodology; determining a third value for the available energy of the battery using a third methodology different from the first methodology and the second methodology; and calculating the composite value; wherein the composite value is in mathematical relation to the first and the second and the third value, and the first and the second and the third methodology each include: measuring a first open circuit voltage of said battery to correlate to and determine a first state of charge; changing a level of energy available in said battery by a measured amount; measuring a second open circuit voltage of said battery after changing the level of energy to determine a second state of charge; dividing the measured amount of energy change in said battery by the calculated change in the state of charge from the first state of charge to the second state of charge to determine the available energy capacity of said battery. 10. The method as defined in claim 9, wherein the first and the second and the third methodology further include: resting said battery for a duration of time before each step of measuring said first open circuit voltage and said second open circuit voltage to obtain a diffusion equilibrium state in said battery. 11. The method as defined in claim 9, wherein the composite value comprises a weighted combination value with at least one of the first and the second and the third value being weighted based on a past history condition of the battery. 12. The method as defined in claim 9, wherein the step of changing the level of energy in the first methodology comprises at least one of: (i) a discharging event, and (ii) a charging event. 13. The method as defined in claim 9, wherein the step of changing the level of energy in the second methodology comprises a charging event, and the charging event uses an overvoltage to charge the battery until a battery charge current attains a predetermined low current value being at a generally unvarying rate, said predetermined low current value being one of: (i) being substantially three amps, and (ii) being greater than zero amps and less than three amps. 14. The method as defined in claim 13, wherein the overvoltage is less than a gassing threshold of the battery. 15. The method as defined in claim 9, wherein the step of changing the level of energy in the third methodology comprises a discharge event, and the discharge event occurs at a current having a generally unvarying rate.
