The possibility of sound design in the electric vehicle battery cooling airflow noise

Abstract

Recently, the automotive industry has been the development of electric vehicles to reduce the impact on the environment for resource depletion and global environmental issues. The electric vehicle has a feature to the idle stop. When the electric vehicle has been idle stop, the inside is very quiet. As a result the user would hear the battery cooling airflow noise. Therefore, even when the battery is hot, we must limit in the amount of battery cooling airflow that does not impair the comfort for the user. And so, we have focused on the sound design. This paper was verify we can provide the electric vehicles battery cooling airflow noise as a delightful sound to user.
