Problems solved by technology

Due to the limited space on the vehicle, a large amount of heat generated by the battery during operation is affected by the space and accumulates, resulting in uneven temperature everywhere and affecting the consistency of the battery cells
[0003] The existing technology uses cooling air to dissipate heat from the battery pack. The battery pack is generally installed under the vehicle body floor, and the cooling air is generally taken from the air-conditioning wind in the cockpit. Energy consumption, and the gas in the battery pack flows into the luggage compartment, which will pollute the cabin air

Abstract

The invention relates to a battery pack applied to electrical vehicles. The battery pack applied to electrical vehicles is arranged below an underbody, a heat-dissipation structure is arranged below the battery pack, and the heat-dissipation structure is a seal structure which is provided with an air inlet and an air outlet respectively along the two ends of a vehicle traveling direction. The battery pack applied to electrical vehicles, disclosed by the invention, is cooled by natural air in a vehicle traveling process without using an air conditioner for auxiliary cooling, thereby saving the limited energy of a pure electric vehicle, improving the endurance mileage of the electric vehicle, and producing no noise and gas pollution influences on a control cabin.

Description

technical field [0001] The invention relates to a battery pack applied to electric vehicles. Background technique [0002] As the main energy storage device of the electric vehicle, the battery pack is a key component of the electric vehicle and directly affects the performance of the electric vehicle. Due to the limited space on the vehicle, a large amount of heat generated by the battery during operation is affected by the space and accumulates, resulting in uneven temperature everywhere and affecting the consistency of the battery cells. [0003] The existing technology uses cooling air to dissipate heat from the battery pack. The battery pack is generally installed under the vehicle body floor, and the cooling air is generally taken from the air-conditioning wind in the cockpit. Energy consumption, and the gas in the battery pack flows into the luggage compartment, which will pollute the cabin air. Contents of the invention [0004] The present invention provides a b...
