Type 1 to Type 2 EV Adapters Explained

With different regions adopting different EV charging standards, EV owners need to be able to switch from Type 1 to Type 2 chargers if they have a Type 1 EV and they need to use a UK granny charger, home charger or public charging station. 

This is where Type 1 to Type 2 EV adapters come in handy, serving as a bridge between Type 1 and Type 2 charging systems and ensuring that EV owners can charge their EVs.

In this comprehensive guide, we delve into the world of Type 1 to Type 2 EV adapters, exploring their use and what to look out for when buying one.

Type 1 to Type 2 EV Adapters

Type 1 to Type 2 EV adapters are essential tools for bridging the gap between different charging standards. These adapters are designed to connect EVs equipped with Type 1 connectors (found in the USA and Japan)  to Type 2 charging stations (found in the UK and the rest of Europe). You can also get Type 2 to Type 1 EV adapters, useful if you need to take your Type 2 EV out of the UK or Europe.

The design of these adapters is both straightforward and functional. On one end, they feature a Type 1 connector, and on the other, a Type 2 connector. They are linked by a robust cable capable of handling high electrical currents. Type 1 to Type 2 adapters are very easy to use, they require no complex setup or installation; it’s a simple plug-and-play piece of kit.

Type 1 to Type 2 adapters are vital for EV owners who frequently travel between regions with differing charging infrastructures or for those who have vehicles imported from markets that use a different charging standard. With these adapters, EV owners can access a broader range of charging stations, either public charging stations or private chargers installed at home.

EV Charging Standard: Type 1 VS Type 2

What are Type 1 Connectors?

Originating primarily from the United States and Japan, Type 1 connectors, also affectionately known as SAE J1772, are a standard for electric vehicles in these regions.

These connectors have a five-pin design and are typically used for single-phase electrical systems, which are common in residential settings. The adaptability of Type 1 connectors to various charging levels, including Level 1 (standard 120V outlets) and Level 2 (up to 240V outlets), makes them a solid choice for EV owners in these regions.

What are Type 2 Connectors?

Type 2 connectors, also known as Mennekes, are prevalent in European countries and are increasingly being adopted globally. These connectors have a seven-pin design and are compatible with both single-phase and three-phase electrical systems, so they have faster charging capabilities.

Type 2 connectors have become the common connection used in Europe, supporting charging levels up to 22 kW, and even higher in some cases with modified setups.

The difference in EV charging standards between Type 1 and Type 2 connectors shows us how EV technology has evolved differently between regions, and also is because there are differences in electrical infrastructure throughout the world.

How Safe are Type 1 to Type 2 EV Adapters?

Type 1 to Type 2 EV adapters are generally considered safe when used correctly and if they meet certain standards and quality checks. Here are some key points that contribute to their safety:

  • Compliance with Safety Standards
    Quality Type 1 to Type 2 adapters are designed and manufactured in compliance with relevant UK electrical safety standards. These standards ensure that the adapters can handle the electrical currents they are rated for without overheating or causing electrical faults.

  • Built-in Safety Features
    Many adapters come with built-in safety features such as surge protection, temperature control, and waterproofing. These features help prevent electrical accidents and damage to the vehicle or the charging station.

  • Proper Usage
    Safety also depends on using the adapter as intended. This includes ensuring compatibility with the vehicle’s and charging station’s specifications, not using the adapter in wet conditions unless it’s rated as waterproof, and regularly inspecting the adapter for damage or wear.

How to Compare Type 1 to Type 2 EV Adapters

Finding the best Type 1 to Type 2 adapter for your EV is crucial if you don’t have the right connection for the available chargers. There are several factors to consider when choosing the right adapter:

Understanding Compatibility and Power Ratings
The first step in choosing the right Type 1 to Type 2 adapter is to understand the compatibility with your EV and the charging stations you intend to use. The adapter’s power rating is a critical factor – it must be compatible with both your vehicle’s charging capabilities and the power output of the charging station. Using an adapter with an inappropriate power rating can lead to inefficient charging or, worse, damage to your vehicle or the charging station.

Cable Length and Durability
The length of the cable on the adapter can affect how conveniently you can charge your EV. A longer cable offers more flexibility in terms of distance from the charging station but can be more cumbersome to handle and store with an EV cable holder.  The durability of the cable is important. Look for cables that are thick, robust, and have a high-quality outer sheath to withstand regular use and environmental factors.

Safety Features
Safety should always be a top priority. Look for adapters that come with essential safety features like the ones mentioned in the previous section. Also, ensure that the adapter has been tested and certified by recognised safety standards. 

Brand Reputation and Reviews
Consider the brand reputation and user reviews when selecting an adapter. Established EV charger brands with positive user feedback such as Vorsprung, fnrids and Evjuicion are often a safer bet, as they are well-known EV charger and accessory brands, more likely to adhere to quality and safety standards.

Warranty and Support
Check the warranty period and what it covers. Additionally, consider the manufacturer’s customer support services, as responsive and helpful support can be invaluable in case you encounter any issues with the adapter.

Tips for Using Type 1 to Type 2 EV Adapters

While electric vehicles are designed to be charged safely without constant supervision, it’s advisable to periodically check on your vehicle during the charging process, especially when using an adapter with a portable 3-pin granny charger. Portable chargers might not have the same smart charge monitoring capabilities as a home smart charger, and therefore monitoring them helps in the early detection of any potential issues. 

Many Type 1 to Type 2 adapters are built to withstand a range of weather conditions, but extreme weather can still pose a risk. Exposure to heavy rain or snow, for instance, can potentially lead to electrical hazards or damage the adapter. To avoid such risks, try to use the adapter in a sheltered area or during favourable weather conditions. If you must charge in less-than-ideal weather, ensure that both the adapter and the charging port are dry before connecting, and consider using a waterproof cover for extra protection.

How you store your adapter when it’s not in use is crucial in maintaining its condition and functionality. Always store the adapter in a dry, cool place away from direct sunlight. Try to use EV charger cable holders to avoid training the cable or the adaptor on the ground. Also, try and keep it out of the sun for long periods and prolonged exposure to heat and UV rays can degrade the materials of the adapter, leading to issues like brittleness. Similarly, storing the adapter in a damp environment can cause corrosion or electrical faults.

The Final Word on Type 1 to Type 2 EV Adapters

Type 1 to Type 2 EV adapters are really important for EV owners travelling between charging regions. Different regions often have distinct connection types for EV charging connectors. For instance, Type 1 connectors are commonly used in North America and Japan, while Type 2 connectors are prevalent in Europe. When EV owners travel between these regions, they will encounter charging stations incompatible with their vehicle’s built-in connector. Type 1 to Type 2 adapters resolve this issue by allowing EVs with Type 1 connectors to use Type 2 charging stations.

Throughout this guide, we’ve explored the nuances of Type 1 to Type 2 adapters, delved into and provided insights into selecting, using, and maintaining these accessories.

As electric vehicle technology continues to evolve, the role of adapters like these might change and we will hopefully have a more uniform charging infrastructure where they are no longer needed! However, for now, they remain a necessary component in the toolkit of EV owners.
