Electric Car Controller and Standards in Different Countries

As an expert in the field of electric car controllers, I would like to explain how these devices work and discuss the standards that govern their use in different countries.

The Role of Electric Car Controllers

An electric car controller, also known as an electric vehicle motor controller, plays a crucial role in managing the power flow between the battery pack and the motor. It controls various aspects of the motor’s operation, such as speed, torque, and regenerative braking.

Their expertise lies in designing innovative AC drives (also known as variable frequency drives), electric vehicle motor controllers, bidirectional DC sources, and test rigs equipped with advanced control capabilities.

Standards for Electric Car Controllers

The use of electric vehicles has been rapidly increasing worldwide. To ensure safety and compatibility among different manufacturers’ products, various countries have established standards for electric car controllers:

United States

In the United States, electric car controllers must comply with regulations set by organizations such as SAE International (Society of Automotive Engineers) and UL (Underwriters Laboratories). These standards cover aspects like electrical safety requirements, electromagnetic compatibility (EMC), performance testing procedures, communication protocols between components within the vehicle system.

European Union

In the European Union, electric car controllers must adhere to regulations set by the European Committee for Electrotechnical Standardization (CENELEC) and the International Electrotechnical Commission (IEC). These standards ensure safety, performance, and compatibility across member states.


In China, electric car controllers are subject to standards established by organizations such as GB/T (Guobiao) and QC/T (Quality Certification Center of Automotive Products). These standards cover aspects like safety requirements, electromagnetic compatibility, energy efficiency, and communication protocols.


Electric car controllers play a vital role in managing power flow within electric vehicles. Companies like GTAKE have made significant contributions to this field through their expertise in low-voltage AC drive applications and new-energy vehicle motor controllers. Additionally, adherence to international standards ensures the safety and compatibility of these devices in different countries around the world.
