High-voltage connector devices, electric vehicle powertrains and electric vehicles

Abstract

The invention discloses a high voltage socket connector device, an electric vehicle and a power system of the electric vehicle, and the high voltage socket connector device is applied to the power system of the electric vehicle. The high voltage socket connector device comprises a male plug portion and a female plug portion, the male plug portion is provided with a first contact assembly, the female plug portion is provided with a second contact assembly, a triggering assembly and a control chip, the second contact assembly matches the first contact assembly, and the triggering assembly is connected with the control chip. In the process that the male plug portion is connected with the female plug portion, the triggering assembly is triggered to generate a triggering signal when the first contact assembly cooperates with the second contact assembly in place, the control chip sends a correct connection signal to a controller of the electric vehicle when receiving the triggering signal, and thus, the controller determines whether the male plug portion and the female plug portion are in a correct connection state. The high voltage socket connector device monitors the connection state of itself in real time, the assembling process is made simple and efficient, and the fault occurrence rate and state false alarm rate are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a high-voltage connector device for an electric vehicle power system, the electric vehicle power system and the electric vehicle. Background technique [0002] Lithium-ion power batteries are used in new energy vehicles. Under normal circumstances, lithium-ion power battery packs are composed of multiple batteries connected in series and parallel. The voltage after the group is generally above 100V, which is an unsafe voltage. On the outside of the battery system box, high-voltage connectors need to be designed and installed to facilitate the output of the power supply and the assembly of the production line. In order to ensure safety, the high-voltage connectors in the related art are generally designed with two-stage safety mechanical locks to prevent the high-voltage connectors from loosening due to vibration or unpredictable factors, but it also brings many difficulties to a...

AI Technical Summary

Problems solved by technology

When this kind of high-voltage connector is used in practice, due to the large size of the copper column head and the copper brush, and the small size of the low-voltage terminal, when large errors and small errors exist at the same time, it will cause contradictions. It often happens that the high-voltage terminals are installed correctly. The low-voltage terminals are still loose or cannot be inserted correctly
