Problems solved by technology

[0002] At present, with the increase in the use of various types of electric vehicles, strict requirements have been put forward for the safety and reliability of electric vehicles. On the one hand, the battery cannot meet the needs of continuous charging and fast charging during the operation of the vehicle. On the other hand, when the battery is running, the external environment temperature has a very serious impact on the data efficiency of the battery. As a result, the accuracy of the driving parameters of current electric vehicles is insufficient, and the stability and reliability of use are relatively poor. In view of this problem, it is urgent to develop a professional electric vehicle detection method to meet the needs of actual use.

Embodiment 1

[0019] Such as figure 1 Shown a kind of test method of driving range of automobile, comprises the steps:

[0020] The first step is to locate the vehicle to be inspected, park the vehicle to be inspected on the vehicle test platform, and connect the wheels of the vehicle to be inspected to the detection parts of the vehicle to be inspected, and then seal the surrounding area of ​​the vehicle to be inspected so that the vehicle to be inspected is in an airtight environment, and the volume of the closed environment where the vehicle to be inspected is twice the volume of the vehicle to be inspected, and the coaxial distribution between the vehicle to be inspected and the closed environment where the vehicle is located, finally simulate the horizontal asphalt road surface on the vehicle test bench;

[0021] The second step is the detection of the normal driving range. After completing the first step and keeping the temperature of the airtight detection environment where the inspe...

Embodiment 2

[0028] A test method for driving range of an automobile, comprising the steps of:

[0029] The first step is to locate the vehicle to be inspected, park the vehicle to be inspected on the vehicle test platform, and connect the wheels of the vehicle to be inspected to the detection parts of the vehicle to be inspected, and then seal the surrounding area of ​​the vehicle to be inspected so that the vehicle to be inspected is in an airtight The volume of the closed environment where the vehicle to be inspected is located in the environment is 1.5 times the volume of the vehicle to be inspected, and finally the vehicle test bench is simulated on the horizontal asphalt road surface;

[0030]The second step is the detection of the normal driving range. After completing the first step and keeping the temperature of the airtight detection environment where the inspection vehicle is at a constant temperature of 20°C, firstly charge the power supply of the vehicle to be inspected, and th...

Abstract

The invention discloses a vehicle continuous driving mileage test method, which comprises five steps: positioning a vehicle to be detected, detecting a normal state continuous driving mileage, carrying out temperature adjusting test, collecting experimental data, and summarizing the data. According to the present invention, the vehicle continuous driving mileage test method has advantages of strong operability and high data detection precision, can effectively perform simulated operation under a variety of complicated conditions, can completely obtain the high-precision continuous driving parameters of electric vehicles, and can further detect the operation state parameters of electric vehicles under a variety of complicated environments according to the use requirements, such that the reliable design basis can be provided for the design of electric vehicles.

Description

technical field [0001] The invention relates to a method for testing the driving range of an automobile, which belongs to the technical field of electric vehicles. Background technique [0002] At present, with the increase in the use of various types of electric vehicles, strict requirements have been put forward for the safety and reliability of electric vehicles. On the one hand, the battery cannot meet the needs of continuous charging and fast charging during the operation of the vehicle. On the other hand, when the battery is running, the external environment temperature has a very serious impact on the data efficiency of the battery. As a result, the accuracy of the continuous driving parameters of current electric vehicles is insufficient, and the stability and reliability of use are relatively poor. In view of this problem, it is urgent to develop a professional electric vehicle detection method to meet the needs of actual use. Contents of the invention [0003] T...
