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.

Point granting device and point granting method

The battery system includes a secondary battery, a voltage sensor, a current sensor, a temperature sensor, and a processor. The processor is configured to calculate a polarization overvoltage by subtracting a voltage drop amount caused by a DC resistance and a reactive resistance of the secondary battery determined in accordance with a temperature and an SOC of the secondary battery from a voltage difference between OCV and CCV of the secondary battery.

Battery system, vehicle including the same, and method for monitoring secondary battery

A solenoid valve includes: a cylindrical spool that has an annular groove in an outer surface and moves along an axial direction under a driving force generated by a current being applied to a solenoid part; a cylindrical sleeve that has a through-hole capable of communicating with the annular groove and houses the spool; and an urging member that urges the spool by an urging force acting in a direction opposite from a direction in which the driving force is generated. When no current is applied to the solenoid part, a part of the through-hole communicates with the annular groove. When a current is applied to the solenoid part, an area of communication between the through-hole and the annular groove increases as the spool moves under the driving force acting against the urging force.
