A vehicle is disclosed. The present invention aims to suppress generation of dew in a cooling site. A vehicle includes a battery cell having an external terminal, an accommodation case accommodating the battery cell, a cooler that circulates refrigerant inside and cools the battery cell, and a control device that controls a temperature of the refrigerant. The control device calculates an estimated value of a temperature of the external terminal, which is a first temperature. The control device calculates an estimated value of a temperature of a cooling site in the accommodation case that is cooled by the cooler, which is a second temperature. The control device estimates an absolute humidity in the accommodation case based on at least one of the first temperature and a temperature outside the vehicle and a humidity outside the vehicle. In a case where the absolute humidity exceeds a saturated water vapor amount corresponding to the second temperature, the control device increases the temperature of the refrigerant.

The application provides a control method and a power supply device. The power supply device comprises a shell, a dehumidification unit for dehumidification, a radiator, a printed circuit board assembly (PCBA) and a battery cell unit. The dehumidification unit, the radiator, the PCBA and the battery cell unit are arranged in the shell. The PCBA is located between the battery cell unit and the radiator, the PCBA is electrically connected with the battery cell unit, and the radiator is close to the side wall of the shell. The control method is applied to the power supply device. The first temperature of the radiator, the second temperature of the PCBA and the third temperature of the battery cell unit are obtained. When the first temperature, the second temperature and the third temperature meet the preset condition, the dehumidification unit is controlled to work, so as to inhibit the formation of condensation on the surface of the battery cell unit and / or the surface of the PCBA, and reduce the condensation risk in the power supply device.

The present invention provides a power conversion device capable of avoiding or suppressing the influence of condensation of water-fragile parts of electrical equipment and the like with a simple configuration. A power conversion device in which a fragile member including an electronic circuit that is fragile with respect to water is housed inside a housing, the power conversion device being provided with a pear-shaped processing part on which pear-shaped processing is performed at a location on the inner surface of the housing that is separated from the fragile member. Condensation is preferentially generated in the pear land treatment part, and water droplets are retained in the pear land treatment part because the surface tension in the pear land treatment part is large. As a result, condensation in the fragile member can be avoided or suppressed, and dripping of water droplets onto the fragile member can be prevented or suppressed.
