Abstract: When electrified vehicle is a vehicle capable of externally charging electric power, the point granting device imparts a point in accordance with a ratio of the amount of electric power obtained from renewable energy to the amount of electric power charged. In addition, when electrified vehicle is a vehicle traveling using electric power, the point granting device imparts a point in response to the actual electric power cost achieved by the traveling being equal to or higher than the modeled electric power cost.

A stage structure of the graphite is classified into a stage 1 to a stage 4 . The battery includes: an SOC region where the stage 4 and the stage 3 coexist; an SOC region where the stage 3 and the stage 2 coexist; and an SOC region where the stage 2 and the stage 1 coexist. The method includes first and second steps. The first step is estimating an SOC of the battery based on at least one of a voltage and a current of the battery. The second step is determining a charging current to the battery in accordance with the SOC of the battery such that the charging current in the SOC region is larger than the charging current in the SOC regions.

Abstract: A controller of a deterioration estimation device for a secondary battery is configured to acquire a first open circuit voltage when a temperature of the secondary battery is a first temperature and a second open circuit voltage when the temperature of the secondary battery is a second temperature changed from the first temperature, and estimate a degree of deterioration of the secondary battery by using a difference between first and second slopes. The first slope is a ratio of a voltage change obtained by subtracting the first open circuit voltage from the second open circuit voltage to a temperature change obtained by subtracting the first temperature from the second temperature. The second slope is a ratio of the voltage change to the temperature change when the temperature of the new secondary battery has changed from the first temperature to the second temperature.
