The North American market seems to be originally of a serious transition associated to electrical automobile charging – from the Mixed Charging System (CCS1) to Tesla’s North American Charging Normal (NACS) connector. At present, we’ll check out yet another factor – the SAE J1772 (AC) charging connector, additionally known as Kind 1, and its probably gloomy future.

As we all know, Tesla developed its in-house, proprietary charging connector (renamed to NACS), for single-phase alternating present (AC) and direct present (DC) charging situations. In addition to Tesla, it would even be natively supported by Ford, Normal Motors, and Rivian, beginning in 2025 (really in 2024 via adapters to CCS1).

Within the case of the CCS1 and the European CCS2, these connectors had been developed for DC quick charging, utilizing an AC charging connector as a base (for backward compatibility) – respectively SAE J1772 (Kind 1) in North America and IEC 62196-2 (Kind 2) in Europe. In consequence, there are these connectors:

• CCS1 advanced charging inlets for:
  SAE J1772 (Kind 1) AC plugs (1-phase)
  SAE J1772 Combo (CCS1) DC plugs
• CCS2 advanced charging inlets for:
  IEC 62196-2 (Kind 2) AC plugs (1-phase or 3-phase charging situations)
  CCS2 DC plugs

It is best defined by the Charging Interface Initiative (CharIN) affiliation:

The swap from CCS1 to NACS, which we consider is going on proper now, was largely related to DC quick charging.

Nevertheless, if the EV business will swap from the CCS1 charging connector to NACS, then there will probably be no level in protecting J1772.

The producers for positive will probably be putting in just one charging inlet on the automobile facet. Within the case of the NACS charging inlet, it is going to be utilized for each AC and DC charging situations.

EV charging infrastructure will comply with with NACS-compatible dwelling charging models and public/work charging models (probably dual-head models throughout the transition interval).

The J1772 charging factors will serve the older electrical autos and the brand new ones when mixed with a particular adapter. Tesla already provides J1772 to NACS adapters.

Tesla: North American Charging Normal

Tesla charging adapter (AC): J1772 to Tesla proprietary customary

5 or ten years from now, we may be at a very totally different level when EV charging will probably be considerably less complicated than it’s right now, particularly within the transition interval when on high of getting a number of kinds of connectors, we have now a number of kinds of adapters between them.

New EV customers will respect only one plug kind for all charging situations (AC and DC). The facility degree will probably be mechanically negotiated between a automotive and a charging level. In consequence, there will probably be nothing advanced to clarify to beginner EV patrons.
