Embodiment Construction
[0019] In order to make the above objects, features and advantages of the invention more obvious and comprehensible, specific implementations of the invention will be described in detail below.
[0020] In the following description, a lot of specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described here, and those skilled in the art can do it without departing from the meaning of the present invention. By analogy, the present invention is therefore not limited to the specific examples disclosed below.
[0021] The flow process of the air sampling method in the electric vehicle provided by the invention is as follows:
[0022] Open the doors and windows of the inspected vehicle in a stationary state in a confined space, and place it for a set time. This step is to release the polluted air released by the pollution sources in the inspected vehicle except the po...

The invention provides an interior air sampling method and an interior air sampling system of an electric car. The interior air sampling method comprises the following steps: opening doors and windows of a detected car in a static state in an enclosed space, statically placing the car for setting time; closing the doors and windows of the detected car, discharging the power supply of the detected car, and selecting sampling points in the detected car; keeping the doors and windows of the detected car to be closed and collecting the air sample in the detected car in the sampling points. According to the interior air sampling method and the interior air sampling system of the electric car, the power supply of the detected car is discharged to enable the temperature of the power supply to be raised, and air is collected after the organic pollutant gas is volatilized by the power supply, and therefore, the evaluation to the interior air of the electric car is integral, the method facilitates the development of the electric car field.
Description
technical field [0001] The invention relates to the field of vehicle performance parameter testing, in particular to a method and system for sampling air in an electric vehicle. Background technique [0002] At present, the indoor air pollution of automobiles is becoming more and more serious, and consumers are increasingly concerned about the air quality in cars. Exceeding the harmful gas in the car is more harmful to the human body than the harmful gas in the house. It will cause headache, dizziness, nausea, etc. for a long time. In severe cases, it may cause anemia or even cancer. The air pollution in the car will also cause the driver to pay attention. Unable to concentrate, affecting driving safety and causing traffic accidents. The pollution sources in the car mainly come from the car body itself, such as the seats, seat covers, floors, etc. in the car. The second is from the interior decoration of the car. The third is from the small and relatively closed space in th...
