The EV connector is a crucial component in the electric vehicle charging infrastructure, ensuring safe and efficient transfer of energy. The IEC62196 and SAE J1772 standards are two prevalent standards that define the specifications for EV connectors.

The International Electrotechnical Commission (IEC) 62196 standard specifies the dimensions, materials, and performance requirements for EV charging connectors, ensuring compatibility and safety across different markets and regions. It covers both AC and DC charging and is designed to facilitate interoperability between different types of charging stations and vehicles.

The Society of Automotive Engineers (SAE) J1772 standard also defines the specifications for EV charging connectors. It focuses on DC charging applications and emphasizes simplicity, robustness, and cost-effectiveness. The SAE J1772 standard is widely used in the US and is tailored to the specific needs of the American market.

The main difference between the IEC62196 and SAE J1772 standards lies in their scope and application. While the IEC62196 standard covers a broader range of EV charging technologies, including AC and DC charging, the SAE J1772 standard is tailored to DC charging applications. Additionally, the IEC62196 standard places greater emphasis on safety and interoperability, ensuring compatibility across different markets, while the SAE J1772 standard emphasizes the simplicity, robustness, and cost-effectiveness of the connector design.

The American standard and the European standard AC charging pile have some differences in standards and plug types. First of all, the United States uses the J1772 standard, while Europe uses the IEC 62196 standard. This means that AC charging points and plug types for electric vehicles in the United States are different from those in Europe. The American standard charging pile usually uses a rectangular shape plug, while the European standard charging pile uses a circular shape plug.

This difference has led to interoperability issues between US and European charging stations, i.e. a US electric vehicle cannot be charged directly on a European charging station, and vice versa. To solve this problem, some charging pile manufacturers and electric vehicle manufacturers have introduced EV adapters that make charging piles and electric vehicles compatible with different standards.
