Title:
電動車両
Document Type and Number:
Japanese Patent JP7024448
Kind Code:
B2
Abstract:
Provided is an electric motor vehicle including a secondary battery, an electric motor, and a control device that controls an input to and an output from the secondary battery. Using an SOC of the secondary battery, the control device calculates a first OCV that is an OCV based on an assumption of absence of a change in voltage due to polarization. Using a voltage and a current of the secondary battery, the control device calculates a second OCV that is an OCV including a change in voltage due to polarization. When a voltage difference between the first OCV and the second OCV resulting from discharging of the secondary battery is large, the control device augments a limit value of electricity input into the secondary battery to be higher than a limit value when the voltage difference is small.
