Abstract

The invention provides a charging module and an electric automobile, and relates to the technical field of automobiles. The charging module comprises a battery module and a battery management system, and the charging module further comprises a quick charging connector which is connected with the battery module through a quick charging high-voltage line and connected with the battery management system through a low-voltage signal line; the first electromagnetic interference suppressor is connected to the fast charging high-voltage line; the second electromagnetic interference suppressor is connected to the low-voltage signal line; the battery module, the battery management system, the first electromagnetic interference suppressor and the second electromagnetic interference suppressor are arranged in the power battery box body, the quick charge connector is arranged on the power battery box body, and the battery module, the battery management system, the first electromagnetic interference suppressor and the second electromagnetic interference suppressor are arranged in the power battery box body. According to the charging module and the electric vehicle provided by the embodiment of the invention, the electromagnetic interference suppressor is added, so that the problem of coupling failure of high-voltage direct current to the charging module in a high-power charging process is solved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a charging module and an electric automobile. Background technique [0002] The charging voltage of electric vehicle high-power charging technology can reach 700V DC, and the charging current can reach 500A. It can be seen that the high-power charging efficiency is very high. However, the increase in charging power will bring about electromagnetic interference problems. When the high-power charging mode is used, the charging lines include both high-voltage DC lines and low-voltage signal lines such as CC1 and CC2, and the high-voltage and low-voltage wiring harnesses are bound together by insulating materials to form a complete wiring harness. The high-voltage DC line is connected to the high-voltage components of the fast charging equipment, and there is a lot of interference on it. Since the wiring harnesses are bundled together, and the voltage amplitude on the high-volta...
