Structure of plane connector of power conversion and charging system of electric vehicle and connecting method thereof

Abstract

The invention discloses a structure of a plane connector of a power conversion and charging system of an electric vehicle. The structure is characterized in that all high-voltage electrodes and low-voltage electrodes of the plane connector of the power conversion and charging system of the electric vehicle are all arranged on an integral installing seat; an external cable is connected onto a switching seat separated from the integral installing seat; meanwhile, at least one high-voltage electrode is connected with a flexible lead; and the other end of the flexible lead is connected onto the switching seat and is connected with the external cable by the switching seat. The structure not only has the advantages of compact structure, high production and installation efficiency, lower production cost and good interchangeability, but also has the advantages that no influence by the external cable is generated, the installing seat and poles are not deformed, the conducting effect and the waterproof and dustproof effects are good, and the service life is longer and the like.

Description

technical field [0001] The invention relates to a planar connector structure and a connection method of an electric vehicle battery swapping and charging system, and belongs to the technical field of battery swapping and charging of an electric vehicle battery box. Background technique [0002] At present, in the prior art, the planar connectors used for battery replacement (battery or storage battery replacement) or charging of electric vehicles generally adopt a decentralized connection method. The technical solution of "a planar connector structure" is a typical planar connector in a distributed connection mode. Such a connection method has low production and installation efficiency, high production and installation costs, and the number of poles. The relative position accuracy is low; in addition, the planar connector in the prior art directly acts on the external cable on the high-voltage pole or is directly connected to the mounting seat of the high-voltage pole.

Problems solved by technology

[0002] At present, in the prior art, the planar connectors used for battery replacement (battery or storage battery replacement) or charging of electric vehicles generally adopt a decentralized connection method. The technical solution of "a planar connector structure" is a typical planar connector in a distributed connection mode. Such a connection method has low production and installation efficiency, high production and installation costs, and the number of poles. The relative position accuracy is low; in addition, the planar connector in the prior art directly acts on the external cable on the high-voltage pole or is directly connected to the mounting seat of the high-voltage pole. Hard, it is easy to generate interaction force between high-voltage electrodes or mounting bases, resulting in deformation of high-voltage electrodes, or deformation between mounting bases and high-voltage electrodes, and easy to cause virtual contact between poles. These problems are serious It affects the electrification effect of the high-voltage contact; and the pole can only play its role better if it works in a dustproof and waterproof environment, and the planar connectors in the prior art generally have poor dustproof and waterproof effects of the pole. question

Therefore, the use effect of the flat connector of the existing battery-changing and charging system for electric vehicles is still not ideal.
