Background on the J1772 connector
J1772 is currently the gold standard EV charger connector for all U.S. and Canadian electric vehicles and plug-ins. The J1772 EV charging standard was adopted to have one connector type for all EV chargers (EVSEs), whether commercial or residential. The only vehicles up until 2024 not to use J1772 are Tesla. The first electric vehicles in the U.S., such as the Nissan Leaf, Toyota Prius, and Mitsubishi Outlander, had the J1772 type EV connector, and other car makers followed this trend.
J1772 Chargers, also referred to as SAE J1772, represent a standardized electric vehicle (EV) charging connector type developed by the Society of Automotive Engineers (SAE). By standardizing the connector type used for all EVs, the industry aimed to simplify charging and speed up the adoption of electric vehicles in North America. It is known as type 1, SAE J1772, or a non-Tesla connector.
J1772 standard connector will change in the future
It’s important to note that the J1772 standard is changing. Tesla uses a NACS connector, so it is not compatible with a J1722 EV charger. Until mid-2020, all North American vehicles produced until 2024 will have a J1772 connector (except Tesla). From mid-2024 and early 2025, some EV manufacturers will be adopting the NACS (North American Charging Standard) charger connector on their vehicles. NACS, designed by Tesla, Inc., was opened up for use by other car manufacturers in 2022.
Which makers have announced they will move away from J1772 to NACS?
Fisker, Ford, General Motors, Honda, Hyundai Motor Group, Jaguar Land Rover, Mercedes-Benz, Nissan, Polestar, Rivian, and Volvo have announced that starting from 2025, their newly produced electric vehicles in North America will be equipped with the NACS charge port. This will be on a vehicle-by-vehicle basis. This will allow these automakers to provide Tesla Supercharging capability for its NACS-fitted vehicles, which current J1772 connector type are not compatible with. Whilst this opens up a lot of Tesla charging stations to NACS type for manufacturers such as Ford, it puts more pressure on the Tesla charging station infrastructure and limits the ability of a new Ford owner to go to traditional charging stations such as EVGO or Electrify America, where certain NACS adapters are not available.
J1772 Charger Standardization over the last 10 years
The North American market wanted to avoid the situation in Europe especially where different car manufacturers developed different connectors. This created confusion and problems for owners, especially at commercial charging stations where they found that their car did not fit a type J1772 connector. As we mentioned the NACS signatories will somewhat undo this.
J1772 Charger Compatibility
J1772 Chargers up until 2024 are compatible with all North American vehicles such as Chevrolet, Ford, Kia, Hyundai, Volvo, Rivian, Fisker, Subaru, Toyota, and Cadillac (this list is not exhaustive). This compatibility extends to plug-in hybrid electric vehicles (PHEVs), meaning J1772 is currently the standard for all non-Tesla. The benefit of this is that for any non Tesla vehicle currently, any residential or commercial chargers will fit the J1772 connector.
Original advantages of J1772 Chargers
J1772 Chargers offer numerous advantages contributing to their prominence within the EV charging infrastructure:
Global standards
The J1772 connector is used extensively in global markets such as Europe, South Africa and Australia. The means automakers can use the same design for all their cars and avoids the costs of non-standardization.Pulsar Plus can deliver up to 30-35 miles of range per hour. Featuring a super sleek and compact design, this level 2 240V powerhouse can be adjusted from 16A to 40A or 48A depending on the model.
User-Friendly
The J1772 connector is designed to be user-friendly, facilitating straightforward plug-in and disconnect actions. This user-friendliness encourages more individuals to embrace electric vehicles. Many EV owners like that the clip design securely clips the J1772 charger in place mechanically which the NACS EV charger type does not (this is purely done electronically and through the press fit design).
Commercial EV charging infrastructure
Many public charging stations such as EVGo and Electrify America are equipped with J1772 connectors, providing a wider charging solution across North America. This meant EV owners did not need to carry different types of adapter.
Safety
J1772 Chargers incorporate safety features, including interlocking mechanisms and ground fault protection, ensuring secure and hazard-free charging experiences.
J1772 Charger Compatibility
J1772 Chargers up until 2024 are compatible with an extensive array of electric vehicles, encompassing popular brands like Nissan, Chevrolet, Ford, and more. This compatibility extends to plug-in hybrid electric vehicles (PHEVs), rendering J1772 a versatile choice for a diverse range of EV owners.
J1772 Charging Speeds and Levels
J1772 Chargers support various charging speeds and levels, with the specific charging speed contingent upon the capabilities of the electric vehicle (how fast the battery can accept charge) and the charging station (voltage and amperes). While J1772 Chargers can deliver relatively swift charging, they are not categorized as ultra-fast chargers akin to Tesla’s Superchargers. These run at much higher voltages, typically 250 kW at 400 volts.
Level 1 and Level 2 J1772 EV chargers are more typically used for residential charging at 208-to-240-volt levels (there is a range since there is variation in voltage from the grid to the residence). Commercial charging using the J1772 bottom section and a DC section at the top (the top part of the connector accepts a direct current feed instead of an alternating current via the J1772 feed). When a J1772 connector is used for the purposes of commercial charging it is called a CCS1 connector type
J1772 is used for level 1 and level 2 EV charging
Residential EV chargers or EVSEs mostly are J1772. We now provide NACS residential EV chargers (see our NACS EV charger section) also. J1772 type EV chargers are used for Level 2 and Level 1 residential charging, which are 220-240 volt and 120 volts respectively.
