Abstract

The utility model provides a new energy vehicle which comprises a vehicle main body, an IPU, a first battery pack and a second battery pack. The IPU is arranged on the vehicle body, the first battery pack is used for supplying power to the high-voltage system of the vehicle body, and the second battery pack is used for supplying power to the low-voltage system of the vehicle body. The second battery pack is disposed on top of the IPU, and the top of the IPU is provided with a thermal management system located between the IPU and the second battery pack. The IPU is configured with a thermal management system because it dissipates heat. The heat management system of the IPU is arranged between the IPU and the second battery pack, so that the IPU and the second battery pack can share the heat management system, the second battery pack can be subjected to heat management to better supply power to the low-voltage system, and space waste caused by independently arranging one heat management system can be avoided.
