Will Tesla's NACS charging standard interface become widespread?
NACS is a combined AC/DC socket, whereas CCS1 and CCS2 are separate for AC and DC, naturally making the overall size larger than NACS. However, NACS also has a limitation in that it cannot accommodate markets with three-phase AC power, such as Europe and China. Therefore, in markets with three-phase power like Europe and China, NACS is difficult to apply.
So, although Tesla’s charging interface has its advantages, such as size and weight, it also has some drawbacks. The fact that it is a combined AC/DC interface means it is only suitable for some markets, and Tesla’s charging interface is not a one-size-fits-all solution. In my opinion, promoting NACS will be quite challenging. But Tesla’s ambition is undoubtedly large, as can be seen from its name, haha.
However, Tesla’s decision to make its charging interface patents public is undoubtedly a good thing for the industry or sector’s development. The new energy industry is still in its early stages of development and needs companies within the industry to adopt an open attitude, sharing technology for industry exchange and learning while maintaining their competitiveness. This truly is a great benefit.
As for whether NACS will be widely adopted and accepted or replace CCS, we will just have to wait and see.
