Power supply device and vehicle
First Claim
1. A power supply device mounted to a vehicle, comprising:
- a first power storage unit that is chargeable/dischargeable;
an electric power input/output unit for inputting/outputting electric power between said first power storage unit and a charge/discharge device installed external to said vehicle;
said charge/discharge device including a storing unit storing the electric power supplied/received to/from said first power storage unit and a voltage conversion unit performing voltage conversion between said storing unit and said electric power input/output unit;
a detection unit detecting a temperature of said first power storage unit; and
a temperature increase control unit increasing the temperature of said first power storage unit by controlling said voltage conversion unit such that at least one of charging from said storing unit to said first power storage unit and discharging from said first power storage unit to said storing unit is performed when said temperature increase control unit determines based on a detection result of said detection unit that the temperature of said first power storage unit is required to be increased.

Abstract
A power supply device mounted to a hybrid vehicle includes: a capacitor that is chargeable/dischargeable; an electric power input/output unit for inputting/outputting electric power between the capacitor and a charge/discharge device installed external to the hybrid vehicle; a temperature sensor detecting a temperature of the capacitor; and a control device increasing the temperature of the capacitor by performing at least one of charging from the charge/discharge device to the capacitor and discharging from the capacitor to the charge/discharge device when the control device determines based on a detection result of the temperature sensor that the temperature of the capacitor is required to be increased. Thereby, the temperature of the capacitor can be increased without causing a load such as an inverter to consume electric power.
