According to an aspect of the present invention, a battery charge amount detection device is provided. The charge amount detection device includes an SOC sensor that detects a state of charge (SOC) of the battery based on the first standard,
The battery SOC is determined by a first SOC value measured by the SOC sensor based on the first standard and a second country or region determined in a country or region different from the country or region that defines the first standard. A storage device that stores a relationship with a second SOC value measured by the SOC sensor based on the first standard, and a storage device that stores the relationship between the first SOC value measured by the SOC sensor based on the first standard And an arithmetic unit that calculates the SOC value in the second standard using the relationship between the first SOC value and the second SOC value stored in the second standard.
According to the battery charge amount detection device of this aspect, even if the standard of the SOC sensor that measures the SOC value of the battery is different from the standard of the control device and control program for battery charge control, It is not necessary to create a new control device or control program corresponding to the SOC sensor by converting the SOC value between them.
