Embodiment Construction

[0023] The specific embodiment of the present invention will be described in further detail by describing the embodiments below with reference to the accompanying drawings, the purpose is to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and contribute to its implementation.

[0024] The further development of pure electric vehicle and hybrid vehicle technology has solved part of the energy problem. As the main energy storage device loaded with battery packs on electric vehicles, battery packs are key components of electric vehicles and directly affect the performance of electric vehicles. After the high-voltage and high-current plug-in is connected to the adjacent electrical device, the contact core is still kept in the original free state to ensure position consistency. The assembly with the other end of the plug-in on the vehicle is smooth. In the future quick replac...

Abstract

The invention discloses a high-voltage plug-in structure for a quick-change battery pack of an electric vehicle. . The high-voltage plug-in structure of the quick-change battery pack for electric vehicles invented, when there is a limited position deviation when the high-voltage plug-in contacts with the mating end, the high-voltage plug-in and its mating end are assembled through the guiding function of the guiding fillet of the conductive core to ensure assembly Smooth, in the future quick change, it is convenient to replace the battery frequently and ensure the life of its plug-in, so as to improve the efficiency of quick change, maintain good high-voltage circuit performance, reduce faults and avoid potential safety hazards; moreover, the high-voltage plug-in and adjacent electrical components After the connection, the contact core is still kept in the original free state to ensure position consistency.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle power battery systems, in particular, the invention relates to a high-voltage plug-in structure for quick-change battery packs of electric vehicles. Background technique [0002] With the development of social economy, the demand for energy is further increased, and the voice of new energy technology is getting higher and higher. At present, in the automotive industry, the further development of pure electric vehicle and hybrid vehicle technology has solved part of the energy problem. The main energy storage device of the battery pack on the car is a key component of the electric vehicle and directly affects the performance of the electric vehicle. Because the electric vehicle power battery provides high voltage and high current. The power current circuit of an electric vehicle includes several electrical connectors and batteries, etc., and the contact resistance and reliability of the c...
