SAE J1772 & IEC 62196, what is the difference
Table of Contents
Introduction to SAE J1772 and IEC 62196
SAE J1772 is the North American standard for electric vehicle conductive charging, while IEC 62196 is an international set of standards covering EV conductive charging including plugs, sockets, vehicle couplers, and inlets. This article will compare key differences between the two.
Connector Types and Power Levels
The two standards specify different connector types and support different charging power levels. SAE J1772 connectors are often referred to as J Plugs or Type 1, while IEC 62196 defines Type 1 and Type 2 connectors.
Communication Protocols
SAE J1772 and IEC 62196 have differing communication protocols between the EV, EV supply equipment (EVSE), and grid that enable features like charging status data.
Safety Mechanisms
The standards include different safety mechanisms like proximity detection and automatic connector locking to protect users while charging.
Plug, Socket, and Inlet Requirements
SAE J1772 and IEC 62196 have differing dimensional, material, temperature, and durability requirements for conductive charging plugs, sockets, and vehicle inlets.
Testing and Certification Procedures
The standards bodies specify different testing methods to certify charging equipment meets safety and functionality standards before going to market.
Adapters for Interoperability
Adapters can often allow EV drivers to charge on either standard by adapting between connector types when traveling abroad.
Ongoing Revisions and Global Harmonization
As technology evolves, amendments and new editions of SAE J1772 and IEC 62196 standards aim to enable faster charging and better alignment.
Charging Networks and Infrastructure
Real-world public EV charging networks are often built around either the SAE J1772 or IEC 62196 standards depending on location.
Choosing the Right EV Charging Equipment
Understanding the differences between the standards helps buyers select the right charging equipment to meet their needs.
Frequently Asked Questions
What are the main differences between SAE J1772 and IEC 62196?
The key differences are the connector types, communication protocols, testing procedures, and global adoption. SAE J1772 is common in North America while IEC 62196 sees wider international use.
Which charging standard is better?
Neither standard is inherently better, they are just designed to meet different regional needs. IEC 62196 aims for global harmonization while SAE J1772 meets North American requirements.
What charging standard is used in the USA?
SAE J1772 is the standard used for conductive charging in the United States and Canada. Most public charging infrastructure in North America is SAE J1772 compliant.
What charging standard is used in Europe?
IEC 62196 Type 2 connectors and infrastructure are common across most of Europe. Type 2 supports faster charging than SAE J1772 and enables additional smart charging capabilities.
Do I need an adapter to charge my EV abroad?
Yes, most likely. An adapter will allow your EV’s charging inlet to connect to foreign stations using different regional standards. Adapters are available to convert between SAE J1772, IEC 62196 Type 1/Type 2, CHAdeMO, and more.
