EV Charging Connector : A Complete Guide of Its Types and Levels

By -

Electric vehicles (EVs) are fast revolutionizing mobility, and charging infrastructure is critical in facilitating this transition. Different locations and car models use different charging protocols, therefore connection compatibility is critical to understand.

This article discusses all of the primary EV charging connection types, supported power levels, and common uses to assist you in selecting the best charging solution.

Why Are EV Connector Types Important?

  • Every EV charging connection standard specifies:
  • Supported voltage and current levels
  • AC or DC charging capabilities
  • Charging Speed (kW Rating)
  • Vehicle and Region Compatibility
  • Safety communication protocols
  • Choosing the proper connector ensures that your EV charges safely, efficiently, and quickly.

Quick Overview of EV Charging Levels :

1. Level One (AC Charging)

  • Power Source: Single-phase.
  • Power output: 1–3 kW.
  • Use Case: Slow home charging via a regular plug.

2. Level 2 (AC charging)

  • Power Source: Single/Three Phase
  • Power Output: 7–22 kW
  • Use Case: Faster home and public charging stations.
  • Level 3 (DC fast charging)

3. Level 3 Power Source: Direct DC supply.

  • Power Output: 50–350+ kW
  • Use Case: Rapid charging, suitable for highways and long-distance trips.
  • Connectors vary according to the charging level, area, and EV model.

EV Charging Connector A Complete Guide of Its Types and Levels

Types of AC Charging Connectors: 

1. Type 1 (SAE J1772/Yazaki)

  • Region: North America and Japan.
  • Charging: AC single phase.
  • Power: Up to about 7.4 kW.
  • Use Case: Residential and workplace charging
  • Feature: A latch locking device for safety
  • Ideal for small to mid-range EVs.

2. Type 2 (Mennekes)

  • Region: Europe, India, Middle East.
  • Charging: Single and three-phase AC.
  • Power: Up to 22 kW (home); 43 kW (public).
  • Use Case: Most modern EVs sold outside the USA
  • Feature: Popular for public charging because of the increased power capacity.
  • Most EV manufacturers use Type 2 as their standard AC connection.

3. CCS: Combined Charging System

  • Combines Type 1 or Type 2 AC sockets with two extra DC pins.
  • Supports both slow AC charging and quick DC charging using the same connector.
  • Designed for extensive worldwide compatibility.

Variants:

  • CCS1
    • Region: North America.
    • AC Standard: Type 1.
    • DC fast charging speed: up to 200-350 kW.
  • CCS2
    • Region: Europe and India.
    • AC Standard: Type 2.
    • DC fast charging speed: up to 350+ kW.

Advantages:

✔ High demand among current EV manufacturers.
✔ Developed as the global standard for rapid charging.

4. CHAdeMO

  • Region: Japan and several areas of Europe.
  • Power: 50-100 kW (up to 400 kW for updated models).
  • Used by: Nissan Leaf and Mitsubishi EVs
  • Feature: Supports bidirectional charging (V2G).
While CHAdeMO was commonly utilized in early EVs, CCS is currently the preferred option.

5. GB/T (China Standard)

  • Region: China (largest worldwide EV market).
  • Power: 60 kW DC (800 kW projected).
  • Use Case: Most Chinese EVs.
  • Feature: Different pin and communication protocol from CCS.
The future ChaoJi connection attempts to unite Chinese and Japanese standards.

Emerging Global Standard: NACS (Tesla North American Charging Standard)

  • Region: USA, growing internationally.
  • Charging: AC and DC in a tiny socket.
  • Power: Up to 250-350 kW (superchargers).
  • Industry adoption: Major manufacturers including Ford, GM, Volvo, Rivian, Honda, and others moving to NACS.
  • NACS leads the trend in North America by combining reduced connection sizes with high-speed capabilities.

Which Connector Type Should You Choose?

  • For India and Europe: Type 2 and CCS2.
  • For USA: NACS (new EVs) and CCS1 (existing).
  • For Japan: CHAdeMO (legacy) and CCS1/ChaoJi (future).
Public charging stations are becoming more multi-standard, making them compatible with the majority of EVs.

Future Trends for EV Charging Connectors

Future Trends for EV Charging Connectors

  • ChaoJi standard for ultrafast charging (up to 900 kW)
