摘要： An estimation device configured to estimate a charge rate of a battery includes a voltage sensor configured to detect a voltage of the battery, a temperature sensor configured to detect a temperature of the battery, and a processing circuit. The processing circuit is connected to the voltage sensor and the temperature sensor and is configured to execute, while a vehicle is parked, an estimation process of estimating the charge rate of the battery based on a detection voltage and a detection temperature. The detection voltage is detected by the voltage sensor. The detection temperature is detected by the temperature sensor.

摘要： There is provided a vehicle comprising a power storage device; a connecting portion configured to be connectable with an external power source; a converter configured to be connected with the connecting portion and with the power storage device; and a control device configured to control the converter. When the external power source is connected with the connecting portion, the control device performs charging control to control the converter, such that electric power from the external power source is subjected to voltage conversion and is then supplied to the power storage device. On completion of charging of the power storage device, the control device starts a system by using electric power from the power storage device after disconnection of the converter from the external power source.
