Understanding the SAE J1772 Type 1 Connector
The SAE J1772, commonly called Type 1, is the standard AC connector across North America and Japan. It’s been powering electric cars for years, but its dominance is being challenged. This guide explains where you’ll find it, its limitations, and what to expect.
History and Standardization
The SAE J1772 standard was finalized in 2001 and updated in 2009 to support higher AC charging power. It became the de facto standard for AC charging in North America. It’s designed for single-phase AC power, limiting its top speed compared to DC fast chargers.
Where You’ll Find It
This connector is ubiquitous in the United States, Canada, and Japan. You’ll encounter it at home charging stations, public Level 2 AC chargers, and workplace charging spots. Many older EVs and some current models sold in these regions come equipped with a Type 1 port. Networks that heavily utilize Type 1 include ChargePoint and EVgo for their Level 2 offerings.
Realistic Power Levels
The SAE J1772 connector can deliver up to 19.2 kW of AC power. However, the actual power delivered depends on the car’s onboard charger and the station’s output. Early EVs might have had onboard chargers limited to 3.3 kW or 6.6 kW. Newer vehicles often support the full 19.2 kW, meaning a full charge could take as little as 2-4 hours for a moderately sized battery, assuming the station can supply that power.
Adapters and Future Outlook
Adapters for Type 1 exist, primarily allowing NACS (Tesla's connector) vehicles to charge at J1772 stations. However, adapters for Type 1 cars to use NACS stations are less common and not officially supported by all manufacturers. While the SAE J1772 remains active, its role is shifting. Many new vehicles in North America are adopting the NACS standard. Expect to see Type 1 chargers continue to function but potentially be supplemented or replaced by NACS chargers over the next decade.
- Will my EV charge with a Type 1 connector?
- If your electric vehicle was sold in the United States, Canada, or Japan and has a charging port that looks like the Type 1 connector (a round inlet with 5 pins), then yes. Most EVs sold in these regions for the last decade came standard with a Type 1 port for AC charging.
- How fast can I charge with a Type 1 connector?
- The Type 1 connector supports AC charging up to 19.2 kW. In reality, your charging speed depends on your car's onboard charger and the specific charging station. A 19.2 kW station can add roughly 40-50 miles of range per hour for a capable EV.
- Can I use a Type 1 connector if my car has NACS?
- Yes, you can usually use an adapter to connect a NACS vehicle (like a Tesla) to a Type 1 public charger. These adapters are widely available. This allows NACS-equipped cars to utilize the extensive network of J1772 stations.
- Can a Type 1 car use a NACS charger?
- Using a NACS charger with a Type 1 vehicle typically requires an adapter. These adapters are less common than NACS to J1772 adapters. Always check manufacturer compatibility before purchasing an adapter, as not all are universally supported.
- Is Type 1 still relevant for new EVs?
- While Type 1 is still active and widely deployed, its future in North America is uncertain. Many new EV models are adopting the NACS standard. You will still find Type 1 chargers for years, but expect NACS to become the dominant standard for new vehicle sales.
