Illustration: a kind of new energy car battery box

The utility model relates to a battery box of a new energy automobile, comprising a battery case, a box cover is arranged at an upper end of the battery case. A battery pack is arranged inside the battery case, the side wall of the battery case a plurality of first heat dissipation holes are disposed on the cover, and a second heat dissipation hole is disposed on the cover. The lower end of the battery is in contact with the vibration plate, which is disposed between the bottoms of the battery case. A tension spring is disposed between the battery casing and a sound absorbing layer is disposed on the inner wall of the battery case. The utility model can improve the heat dissipation efficiency, reduce the heat accumulation, prolong the service life, and avoid the vibration of the battery pack caused by the driving of the vehicle body, thereby reducing the damage to the battery pack. By setting the sound-absorbing layer, so that we can improve the battery box mute, reduce noise.
