BATTERY MANAGEMENT SYSTEM

摘要

A vehicle controls power consumption of a battery on the basis of a target battery remaining amount set by a user and detects or stores a deterioration-related parameter relating to deterioration of the battery. A server calculates a deterioration parameter coefficient that represents the degree of the effect of the deterioration-related parameter on the deterioration of the battery. The vehicle controls the power consumption of the battery in accordance with the deterioration parameter coefficient and the deterioration-related parameter. The degree of actual battery deterioration is calculated on the basis of the actual battery remaining amount at a point when the vehicle reaches a destination. A table for use in calculating the deterioration parameter coefficient is modified in accordance with the degree of actual battery deterioration.
