Vehicle charging gateway controller with conversion use of national standard and American standard and charging conversion method thereof

Abstract

The invention relates to a vehicle charging gateway controller with conversion use of a national standard and an American standard. An American standard charging standard is adopted between the vehicle charging gateway controller and a vehicle battery management system, and a national standard charging standard is adopted between the vehicle charging gateway controller and a charging station. The vehicle charging gateway controller with conversion use of a national standard and an American standard is characterized by comprising a national standard interface module for being connected with the charging station to simulate the national standard charging standard with the charging station, and an American standard interface module for being connected with the vehicle battery management system to simulate the American standard charging standard with the vehicle battery management system. By using the vehicle charging gateway controller with conversion use of the national standard and the American standard of the invention, the vehicle meeting the American standard can be directly charged in the national standard charging station.

Description

technical field [0001] The invention relates to a vehicle charging technology, in particular to a vehicle charging gateway controller for switching between the national standard and the American standard and a charging conversion method for charging the vehicle between the national standard and the American standard. Background technique [0002] Fast charging technology can charge vehicles in a short period of time through high current, thus solving the problem of long charging time of electric vehicles. Since the current and voltage are relatively high in fast charging, it is necessary to design a more complex charging protocol between the charging station and the vehicle to ensure the safety of the charging process. [0003] At present, the fast charging protocol standards of various countries are inconsistent. The United States uses the SAE standard (SAEJ1772, referred to as the American standard in this article), China uses the national standard (GB20234, referred to as...

AI Technical Summary

Problems solved by technology

The standards of various countries and regions have great differences in hardware and software. Electric vehicles that meet the American standards cannot be fast charged in China.
