Abstract
Official abstract text for this publication.
A vehicle includes a battery pack, an air conditioning system, a communication member, a pack humidity detector, an outside air humidity detector, and a controller. The battery pack contains a battery module. The air conditioning system is configured to regulate humidity of air and send the air. The communication member fluidly connects a blowing port of the air conditioning system and an inside of the battery pack. The pack humidity detector is configured to detect humidity in the inside of the battery pack. The outside air humidity detector is configured to detect humidity of an outside air. The controller is configured to control the air conditioning system so that the humidity in the battery pack is equal to or lower than the humidity of the outside air.
First claim
Opening claim text (preview).
1 . A vehicle comprising: a battery pack housing a battery module; an air conditioning system configured to regulate humidity of air and send the air; a communication member that fluidly connects a blowing port of the air conditioning system and an inside of the battery pack; a pack humidity detector configured to detect humidity in the inside of the battery pack; an outside air humidity detector configured to detect humidity of outside air; and a controller configured to control the air conditioning system such that the humidity in the battery pack is equal to or lower than the humidity of the outside air. 2 . A vehicle comprising: a battery pack containing a housing module; an air conditioning system configured to send air; a communication member that fluidly connects a blowing port of the air conditioning system and an inside of the battery pack; a pressure regulator provided in an air ventilation passage defined by the communication member, the pressure regulator being configured to change pressure of air that passes through the communication member; a pack pressure detector configured to detect pressure in the battery pack; an outside air pressure detector configured to detect pressure of outside air; and a controller configured to control the air conditioning system and the pressure regulator such that the pressure in the battery pack is equal to the pressure of the outside air. 3 . The vehicle according to claim 1 , further comprising: a control chamber disposed at an intermediate part of an air ventilation passage through the communication member, the control chamber having a space that has an air ventilation cross sectional area is larger than an air ventilation cross sectional area of the communication member. 4 . The vehicle according to claim 2 , further comprising: a control chamber disposed at an intermediate part of an air ventilation passage through the communication member, the control chamber having a space that has an air ventilation cross sectional area is larger than an air ventilation cross sectional area of the communication member.
