摘要： A battery degradation evaluation system includes a memory and a processor. The processor is configured to acquire state quantities of a battery mounted at a vehicle, derive probabilities, and evaluate degradation of the battery based on the derivation results. The probabilities are a short-term degradation probability of the battery degrading in a pre-specified short period, a medium-term degradation probability of the battery degrading in a period that is longer than the short period, and a long-term degradation probability of the battery degrading in a period that is longer than the medium period. When a number of the state quantities is smaller, the processor sets a higher weighting for a combined degradation probability for the short period and medium period, which is calculated from the long-term degradation probability. When the number of state quantities is larger, the processor sets a higher weighting for the short-term degradation probability.

摘要： The first step includes performing FFT for a voltage and a current of a battery a plurality of times to thereby calculate the voltage and the current for each frequency. The second step includes determining whether or not the first condition and the second condition are satisfied for the current of the battery that is calculated for each frequency. The third step includes calculating an impedance component of the battery for each frequency range when at least one of the first condition and the second condition is not satisfied, and not calculating the impedance component of the battery for each frequency range when each of the first condition and the second condition is satisfied. The first condition shows that the current in a low frequency range is greater than a reference value. The second condition shows that the current in a frequency range is less than a reference value.

摘要： A method of estimating a deteriorated state of a battery includes steps S102 to S110. S102 is a step of obtaining a voltage and a current of the battery a plurality of times for a data acquisition period. S104 is a step of calculating an amount of change in current, an amount of change in temperature, and an amount of change in SOC during the data acquisition period. S106 is a step of obtaining an allowable amount of change in current, an allowable amount of change in temperature, and an allowable amount of change in SOC based on an average temperature. S110 is a step of calculating an impedance component for each frequency bandwidth based on the voltage and the current by subjecting the voltage and the current to Fourier transform when all amounts of change are smaller than the allowable amounts of change.

摘要： [Summary][Objective] Estimation accuracy in a battery status estimating device which estimates a charge status of a secondary battery should be improved further more.[Means for Solution] In an SOC estimation by integration of a charge-and-discharge current, influence of a sensor error cannot be disregarded, and the influence of such an error is accumulated as time passes. On the other hand, in an SOC estimation based on measured values of a battery voltage and a battery temperature, estimation accuracy largely depends on a load-generation pattern. Then, in accordance with the present invention, by mixing both, while one of them is reset based on a reliability in accordance with an operation situation and/or an input current value which will be the premise for an SOC estimate calculation in a battery model is set up based on the reliability, it becomes possible to compute an SOC estimate in high accuracy as much as possible in accordance with the operation situation.
