Description

Technical Field

[0001] The present invention relates to the technical field of new energy vehicle maintenance, and in particular to a practical operation platform for new energy vehicle fault detection. Background Art

[0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines, including pure electric vehicles, hybrid vehicles, hydrogen energy vehicles and solar vehicles. With the continuous development of technology, new energy vehicles have the advantages of high efficiency, environmental protection and low carbon, and have been widely used in countries around the world. At present, new energy vehicles have occupied 30% to 60% of the automobile market. In addition, with the support of the state's purchase subsidies for new energy vehicles, it has also greatly promoted the rapid development of new energy vehicles. However, new energy vehicles are emerging things after all. There are problems such as immature automobile manufacturing technology, low electricity and battery technology, and backward fault diagnosis and detection equipment for new energy vehicles. Therefore, the probability of failure of new energy vehicles is relatively high. A pure electric vehicle is a car that uses a single battery as an energy storage power source. It uses a battery as an energy storage power source, provides electricity to the motor through the battery, drives the motor to run, and thus drives the car to drive. The rechargeable batteries of pure electric vehicles mainly include lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries and lithium-ion batteries, which can provide power for pure electric vehicles. At the same time, pure electric vehicles also use batteries to store electricity to drive the motor to run normally.

[0003] The vigorous development of pure electric vehicles has led to the widespread application of related supporting industries. With the popularization of electric vehicles, the battery pack on the vehicle has become an indispensable accessory, and the inspection and maintenance of battery packs has become a hot project. Therefore, a large number of battery pack inspection and maintenance equipment are needed, and a large number of battery pack repair and maintenance talents are needed.

[0004] After searching, the Chinese utility model patent with application number "202420434917.1" discloses a new energy vehicle fault setting and detection training platform, including a base plate and a teaching display screen, a shell is installed on the upper end surface of the base plate, a workbench is installed on the upper end surface of the shell, a placement groove is installed on the upper end surface of the workbench, a measurement panel is arranged in the placement groove, an upper drawer is installed on the rear end surface of the shell by sliding cooperation, a fault panel is arranged at the bottom of the upper drawer, a fixing frame is installed on the upper end surface of the workbench, a mounting plate is installed on the front end surface of the fixing frame, and a teaching display screen is installed on the front end surface of the mounting plate. The fault setting and detection connection platform used in the utility model should be convenient for teachers to set faults and students to learn data measurement, which is conducive to improving students' basic ability to diagnose and eliminate simple faults of new energy vehicles.

[0005] However, the above-mentioned new energy vehicle fault setting and detection training platform has a single function and cannot meet the needs of multi-faceted practical training. Many new energy teaching aids only take out one of the subsystems on the car body as a teaching aid training platform, which has limitations in the practical training process and can only achieve demonstration teaching of a certain function. The practical training projects that can be carried out are single and limited in function. It cannot meet the students' multi-faceted practical training needs at the same time and lacks practicality. When students use teaching aids for practical training, they cannot master the integrity and comprehensiveness of professional skills training well, and are largely separated from the real situation of actual car repair, resulting in the problem that the technology learned by students cannot be truly used in actual production.

[0006] To sum up, there is an urgent need for a new energy vehicle fault detection practical platform to solve the above problems. Summary of the invention
