Secondary battery system and method for estimating deterioration state of secondary battery system |
| abstract |
The present invention provides a secondary battery system and a method for estimating a deterioration state of the secondary battery system. The secondary battery system includes a secondary battery, a circuit and an electronic control unit. The electronic control unit is configured to execute the first calculation control, the second calculation control, and the estimation control when a predetermined condition is satisfied. The first calculation control is a control for calculating the first impedance of the secondary battery based on the voltage value of the secondary battery when the current value of the secondary battery is changed in a first cycle. The second calculation control is a control for calculating the second impedance of the secondary battery based on the voltage value of the secondary battery when the current value of the secondary battery is changed in a second cycle. The estimation control is control for estimating the reaction resistance of the secondary battery from the difference between the first impedance and the second impedance. |
