Although the new energy automobile consumption market in China is developed in a blowout mode in recent years, professional maintenance personnel in the market after the new energy automobile is lost seriously. The method not only influences the after-sale service experience of the vehicle owners who have purchased the new energy vehicles at present, but also restricts the healthy development of the whole new energy vehicle market in the future. Therefore, in China, vocational colleges and universities of high-rise and medium-high-class have been provided with specialized automobile repair professions for new energy vehicles, and meanwhile, general colleges and universities configure training teaching aids matched with teaching contents for teachers, wherein the common training teaching aids on the general market of the new energy pure electric vehicles are five sets commonly known in the industry, namely a battery training platform, a motor training platform, an air conditioner training platform, an electric appliance training platform and a steering training platform.

When designing a pure electric vehicle five-piece training teaching aid, a person skilled in the art generally sets a panel on a battery training platform, a motor training platform, an air conditioner training platform and an electric appliance training platform, and sets a terminal on the panel. The original intention of those skilled in the art to add panels and terminals is to allow each student to perform fault setting, fault detection and fault diagnosis on a battery part, a motor part, an air conditioner part or a whole vehicle electrical part through the terminals.

However, in practical training teaching, after a teacher explains the battery practical training platform, the motor practical training platform, the air conditioner practical training platform, the electrical appliance practical training platform and the steering practical training platform, because the battery practical training platform, the motor practical training platform, the air conditioner practical training platform and the electrical appliance practical training platform only have one panel corresponding to each other, the teacher generally can only select several students to perform detection training in turn and cannot cover each student, so that the practical training teaching efficiency is low and the practical teaching ability of the students is poor.

In order to solve the above problems, a person skilled in the art needs to develop a detection platform matched with a pure electric vehicle training device to meet the requirement of training teaching.
