EV Connector Types. The Complete Wiring & Pinout Guide
There are seven major EV charging connector standards in the world. If you work with chargers. designing them, installing them, or writing the software that runs them. you need to know what's inside each plug. Not just "Type 2 is European." The actual pins, the signaling voltages, the wire gauges, the physical differences that determine whether a charger can deliver 7 kW or 350 kW.
This series covers every connector in production use today.
The connectors
| Connector | Region | AC / DC | Max Power | Posts |
|---|---|---|---|---|
| Type 1 (SAE J1772) | North America, Japan | AC only | 19.2 kW | Read more |
| Type 2 (Mennekes) | Europe, global | AC | 43 kW (3-phase) | Read more |
| CCS1 (Combo 1) | North America | AC + DC | 350 kW | Read more |
| CCS2 (Combo 2) | Europe, global | AC + DC | 350 kW | Read more |
| CHAdeMO | Japan, legacy | DC only | 400 kW | Read more |
| NACS (Tesla / SAE J3400) | North America | AC + DC | 350 kW+ | Read more |
| GB/T | China | AC + DC | 250 kW (900 kW future) | Read more |
How to read these posts
Each post in this series covers:
- Physical layout: what the plug looks like, how many pins, locking mechanism
- Pin assignments: every pin identified with its function
- Wiring: conductor sizes, recommended cable types, shielding
- Signaling: Control Pilot (CP), Proximity Pilot (PP), how the car and charger negotiate
- Electrical specs: voltage ranges, current limits, power levels
- Compatibility: what adapters exist, what works with what
- Deployment notes: practical things that matter when installing or servicing
