What is Type 1 and Type 2 EV Charging?

As the popularity of electric vehicles (EVs) continues to grow, it is crucial to have a clear understanding of the different types of charging options available. Two commonly used charging standards are Type 1 and Type 2. In this article, we will delve into the technical aspects of Type 1 and Type 2 EV charging, exploring their features, compatibility, and advantages.

Type 1 EV Charging

Type 1, also known as SAE J1772, is one of the earliest charging standards developed in North America. It consists of a five-pin connector that allows for both AC and DC charging. The Type 1 connector can be found on many older generation electric vehicles.

AC charging using Type 1 involves single-phase power supply with a maximum power output of 7.4 kW. This is suitable for overnight charging at home or at public charging stations. On the other hand, DC charging using Type 1 supports rapid charging, allowing for quick top-ups on long journeys. However, DC charging requires additional hardware, such as a CHAdeMO adapter, to convert the current from AC to DC.

Type 2 EV Charging

Type 2, also known as Mennekes, is a charging standard widely adopted in Europe and gaining popularity globally. It utilizes a seven-pin connector, offering greater charging capabilities compared to Type 1. The Type 2 connector is compatible with both AC and DC charging.

In terms of AC charging, Type 2 provides three-phase power supply, enabling a higher power output ranging from 11 kW up to 22 kW or even more. This makes Type 2 charging ideal for faster home charging or public charging stations, significantly reducing the charging time compared to Type 1. Additionally, Type 2 supports optional features like smart grid communication, allowing for better integration with renewable energy sources and more efficient charging.

For DC charging, Type 2 also offers rapid charging capabilities similar to Type 1. The introduction of Combo Type 2 (CCS) connectors combines the Type 2 connector with additional DC pins, providing a higher-level fast charging option without the need for separate adapters.

Conclusion

In conclusion, both Type 1 and Type 2 EV chargers have their own strengths and applications depending on geographic location and vehicle compatibility. Type 1 is prevalent in North America and offers charging options suitable for various scenarios, while Type 2 is widely used in Europe and provides faster AC charging speeds. The ongoing development of technology and charging infrastructure will continue to shape the landscape of electric vehicle charging.

Whether you are an EV owner or planning to switch to electric vehicles, understanding the differences between Type 1 and Type 2 charging can help you make informed choices when it comes to selecting chargers and accessing the appropriate charging infrastructure.
