Latest Patents
Koike's latest patents include a battery state estimating apparatus that features an updating unit. This unit updates a charge-transfer impedance model in a battery model of a secondary battery. The model consists of a series connection of a DC resistance model, a charge-transfer impedance model, and a diffusion impedance model. The updating process uses the amount of change in a measurement value of the current flowing through the secondary battery. This ensures that the first relationship between the current and voltage across the charge-transfer resistance approaches a second relationship based on actual values. The first relationship is defined using the Butler-Volmer equation. Additionally, he has developed another battery state estimation apparatus that estimates the state of a secondary battery based on a comprehensive battery model. This model includes a DC resistance model, a reaction resistance model, and a diffusion resistance model, which are essential for accurate state estimation.
