NACS adapter introduction and advantages

There are three types of DCFC connectors in the United States.In addition to the combined charging system (CCS1) and CHAdeMO, the NACS connector is one of several connector types that enable fast charging of electric vehicles (EVs). NACS can also be used for AC Level 2 charging and is compatible with the J1772 connector via an adapter.

Compared with the current CSS interface in North America, the Tesla NACS supercharger adopts an integrated ultra-thin package design, with AC and DC integrated, and a maximum DC charging power of up to 1000kW, while the size is only half of the CCS charging gun. The NACS supercharger interface has been recognized for its multiple advantages:

(1) Fast charging speed. According to official data, the Tesla supercharger interface can charge 80% of the battery in 30 minutes, which can provide car owners with fast energy replenishment needs.

(2) Humanized design. There is a large screen on the supercharger interface that can display the charging progress and power level. It also supports touch operation, which is convenient and fast for users to select charging mode and query charging records.

(3) Extremely high safety. The interface adopts multiple safety protection mechanisms, which can not only automatically detect the battery condition and charging environment during charging to avoid battery overheating or overcharging, but also is equipped with lightning protection and fire protection systems to ensure the safety and stability of the charging process.

The NACS charging gun standard also supports basic communication protocols to facilitate necessary communication and control between electric vehicles and charging piles. These communication functions include the transmission of information such as charging status, charging power, and charging time.

NACS is an integrated AC and DC socket, while CCS1 and CCS2 are separated in AC and DC, so the overall size is naturally larger than NACS. This standard supports single-phase AC charging with a maximum power of 80 amperes, and is usually used for home charging piles, public charging stations, and commercial charging facilities. However, NACS also has a limitation, which is that it is not compatible with markets with AC three-phase electricity, such as Europe and China. Therefore, NACS is difficult to apply in markets with three-phase electricity such as Europe and China.
