Type 1 connector (SAE J1772, conector tipo 1)

What the Type 1 connector is

The Type 1 connector, also known as SAE J1772 or Yazaki, is an AC charging plug that originated in the United States and Japan. It has five contacts: two for power, one for earth (ground) and two for communication with the charger.

Features

• Single-phase only: no three-phase charging.
• Up to 7.4 kW, at 32 A and 230 V.
• No locking of its own at the socket: locking depends on the car.

In Europe the compulsory standard for public AC charging is Type 2, which also handles three-phase, so Type 1 is fading out.

Which cars have it

Mainly older Japanese and American models, such as the first generation Nissan Leaf or early versions of the Mitsubishi Outlander PHEV. Electric cars sold in Europe today have Type 2 for AC and CCS Combo 2 for rapid charging. If you brought a car from the US, check which connector it has.

How to charge a Type 1 car

• At home: with a wallbox with a tethered Type 1 cable, or a wallbox with a Type 2 socket and a Type 2 to Type 1 cable.
• On the street: public AC points have Type 2 sockets, so you need to carry your own Type 2 to Type 1 cable.
• Power: even if the point offers 11 or 22 kW, the car charges at no more than its onboard charger and the Type 1 connector allow.

When installing your charger

If you have a Type 1 car and plan to change it soon, a wallbox with a universal Type 2 socket and an adapted cable usually pays off: it will also serve your next car. See home EV charger for a house in Seville, Spain.
