Today’s hot topic in the EV world is understanding the differences between a J1772 and a NACS connector. In this article, I will explain what they look like, what are the differences, which care makers use J1772 or NACS, and what are the future trends
What is the J1772 connector?
J1772 refers to the type of connector that is on the end of the charging cable that connects to the charging receptacle on a vehicle. It is a 5-pin electrical connector standard that supports single-phase alternating current (AC) charging rates.
What is the J1772 connector also known as?
J1772 is also referred as a type 1 connector or SAE J1772
Benefits of the NACS design
Based on my use of NACS and J1772 designed charging cable, the NACS cable and connector is lighter, easier to connect, more maneuverable, and thinner.
Conclusion
The medium-term trend over the next 5-8 years will be the adoption of the NACS connector. Tesla has built a superior connector, has more infrastructure, and available charging stations that are more reliable with superior payment technology. J1772 will remain prevalent due to its use for the last decade on all EVs and plug-in hybrids but will slowly be phased out by car manufacturers.
