Power battery compartment

Abstract

The invention discloses a power battery compartment for a new energy vehicle. The new energy automobile comprises a power battery compartment body and a battery box arranged in the power battery compartment body, wherein the power battery compartment body is provided with a first air inlet communicated with a compartment of the new energy vehicle and an air outlet communicated with the outside of the compartment, a power battery is arranged in the battery box, a second air inlet is arranged at the position close to the first air inlet of the battery box, and an exhaust fan is arranged at the position close to the air outlet of the battery box. A partition plate for preventing air flow short circuit is arranged between the power battery compartment body and the battery box. The power battery compartment utilizes air-conditioning air in the compartment to cool the power battery, the air-conditioning air in the compartment is kept within a certain temperature range and does not change with the changing environment outside the compartment, the cooling effect of the power battery is effectively ensured, the influence of the power battery on a vehicle body and a chassis structure is reduced, and the comfort degree of an in-vehicle environment is improved.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a power battery compartment. Background technique [0002] The power battery of a new energy bus has a large volume and weight, and is generally installed on the roof, interior or chassis of the vehicle. The power battery will generate heat during the use of the battery, and the heat generated needs to be dissipated in time to prevent the temperature of the power battery from Too high will affect the service life. The heat generated by the power battery is generally cooled by cold air, that is, the heat of the power battery is absorbed by the cold air to reduce the temperature of the power battery. The source of cold air is generally natural wind. When the ambient temperature outside the car is low, the natural wind can have a good cooling effect on the power battery. However, in high temperature weather, the temperature of the natural wind outside the car is also high. ...

AI Technical Summary

Problems solved by technology

The source of cold air is generally natural wind. When the ambient temperature outside the car is low, the natural wind can have a good cooling effect on the power battery. However, in high temperature weather, the temperature of the natural wind outside the car is also high. The wind cannot effectively cool the power battery, and the cooling effect is not ideal, and the natural wind will carry impurities such as dust and rain, causing pollution to the power battery

In addition, if the battery box is installed in the car, the air-conditioning air in the car can be extracted to cool the battery box, but the installation of the battery box in the car will affect the layout of the chassis and body, occupy passenger space, and it is inconvenient to disassemble and assemble. It may form crosstalk with the air in the cabin, and the dust outside the vehicle may enter the cabin through the battery cooling channel, affecting the comfort of the car
