AUTHENTICITY DETERMINATION APPARATUS AND AUTHENTICITY DETERMINATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a battery authenticity determination apparatus capable of appropriately determining whether batteries mounted on a vehicle are proper products.SOLUTION: The battery authenticity determination apparatus includes: a sensor unit 100 that detects terminal voltage on a battery and charging/discharging current; an open circuit voltage calculation section 201 that calculates an open circuit voltage at charging/discharging based on the terminal voltage detected by the sensor unit 100; a capacity calculation section 202 that calculates the capacity of a battery based on the charging/discharging current detected by the sensor unit 100; and an authenticity determination section 400 that determines whether or not the battery is proper product based on the open circuit voltage calculated by the open circuit voltage calculation section 201 and the capacity calculated by the capacity calculation section 202.
