Introduction to Understanding the J1772 EV Charger Standard
Electric vehicles (EVs) are becoming increasingly popular as a means of transportation due to their environmentally-friendly operation and low fuel costs. However, one of the challenges facing the widespread adoption of electric vehicles is the lack of a uniform charging standard. Different countries and regions have developed their own charging standards, which can make it difficult for electric vehicle owners to charge their vehicles when traveling. This is where the J1772 EV Charger Standard comes in.
To address this issue, the International Electrotechnical Commission (IEC) has established international charging standards for electric vehicles. These standards ensure that charging stations are compatible with all types of electric vehicles, regardless of the manufacturer.
One of the most widely-used charging standards is the J1772 EV Charger Standard. Developed by the Society of Automotive Engineers (SAE), the J1772 standard defines the physical and electrical characteristics of an EV charging connector. It specifies the voltage, current, and communication protocols used by charging stations to communicate with electric vehicles.
The J1772 standard is widely used in North America and is supported by many leading electric vehicle manufacturers, including Tesla, Chevrolet, Nissan, and BMW. This widespread adoption of the J1772 standard has helped to ensure that electric vehicle owners can charge their vehicles at a variety of charging stations.
History of the J1772 Standard
The J1772 standard was developed by the Society of Automotive Engineers (SAE) in response to the growing need for a uniform charging standard for electric vehicles. The standard was first published in 2009, and it was designed to be a universal charging standard that could be used by all electric vehicle manufacturers.
The J1772 standard was quickly adopted by the electric vehicle industry and is now widely used in North America. Many leading electric vehicle manufacturers, including Tesla, Chevrolet, Nissan, and BMW, have incorporated the J1772 standard into their charging systems. This has helped to ensure that electric vehicle owners can charge their vehicles at a variety of charging stations.
The J1772 standard has evolved over time to meet the changing needs of the electric vehicle industry. For example, in 2013, the SAE released an updated version of the J1772 standard, J1772-2013, which increased the maximum charging power from 5.7 kilowatts to 19.2 kilowatts. This change has allowed for faster charging times and has helped to support the growth of the electric vehicle industry.
In addition, the J1772 standard is still under development to support new technologies, such as fast charging and wireless charging. These updates will continue to help the electric vehicle industry grow and evolve, ensuring that electric vehicles are an attractive and practical alternative to traditional gasoline-powered vehicles.

It suits the needs of different electric vehicles by adjusting it. This flexibility ensures efficient and effective charging for electric vehicles, regardless of the station used.
How the J1772 EV Charger Standard Works
The J1772 standard governs the charging process for electric vehicles. It begins when the electric vehicle is connected to the charging station via the J1772 charging connector. The charging station then communicates with the electric vehicle to determine the vehicle’s charging requirements, such as the maximum voltage and current. The charging station then adjusts its output to meet these requirements, and the electric vehicle begins charging. The process continues until the electric vehicle is fully charged or the charging station is disconnected.
The J1772 charging connector is the physical interface between the electric vehicle and the charging station. The connector is compatible with a wide range of electric vehicles, regardless of the manufacturer. The J1772 charging connector’s design is easy to use, with a simple locking mechanism to prevent accidental disconnection during charging.
The charging control box is the electronic component of the J1772 charging station that communicates with the electric vehicle and manages the charging process. The control box includes a microprocessor that controls the output of the charging station and monitors the charging process. It also includes safety features to prevent overcharging and other safety issues.
The charging control circuit is the electrical component of the J1772 charging station that manages the flow of electricity between the charging station and the electric vehicle. The control circuit meets J1772 standards for maximum charging voltage and current. The control circuit also includes safety features to prevent overcharging and other safety issues.
In summary, the J1772 standard governs the entire charging process for electric vehicles. Starting from the physical interface and communitcation between the electric vehicle and the charging station, to the flow of electricity during the charging process. This comprehensive approach helps to ensure that electric vehicle charging is safe, efficient, and accessible to all.
