Title:
ESTIMATION SYSTEM, AND ESTIMATION PROGRAM
Document Type and Number:
Japanese Patent JP2022071900
Kind Code:
A
Abstract:
To provide an estimation system and an estimation program capable of improving estimation accuracy of the remaining amount of charge or deterioration of a battery.SOLUTION: A server device 4 that estimates the remaining amount of charge or deterioration of a battery 11 of a vehicle 1 includes at least: an acquisition unit 431 that acquires discharge current information indicating an actually measured current amount at the time of discharging the battery 11 and discharge voltage information indicating an actually measured voltage value at the time of discharging the battery 11; and an estimation unit 432 that estimates the remaining amount of charge or deterioration of the battery 11 based on the discharge current information and the discharge voltage information acquired by the acquisition unit 431. The estimation unit 432 calculates a discharge amount of the battery 11 based on the discharge current information and the discharge voltage information acquired by the acquisition unit 431 and estimates the remaining amount of charge of the battery 11 based on the calculated discharge amount of the battery 11 and an estimated full charge capacity estimated as the maximum charge capacity of the battery 11.SELECTED DRAWING: Figure 1
