Comparing Tethered and Untethered EV Chargers

On this page
As society moves toward electric vehicle mobility, the complexity of EV charging technology becomes particularly critical. Tethered chargers with pre-connected cables provide a simple plug and play experience, while untethered charging solutions that require a separate cable provide greater flexibility and adaptability. Understanding the distinctive features and differences of these charging methods can help optimize the user experience of electric vehicles and ensure a seamless journey.

This article will explore the characteristics of tethered chargers and untethered chargers in depth. Whether you own an electric vehicle for the first time or are looking to upgrade your existing charging infrastructure, this guide will provide you with valuable insights to help you choose the charging option that best suits your needs.

Comparing Tethered and Untethered Chargers

Tethered EV Chargers

A tethered electric vehicle charger is a charging device with a fixed cable that provides a convenient plug and play experience. They are usually mounted on walls or struts and connected to the home electrical system. Users simply plug the charging cable into the vehicle to start charging. The cable length of the tethered charger is usually 5 to 8 meters to adapt to different parking layouts. These devices are available in single-phase and polyphase (i.e., three-phase) options, with single-phase devices suitable for home use and polyphase devices for commercial environments that require fast charging. Common connector types are type 1 and type 2, of which type 1 is used more in the United States and type 2 is more common in Europe.

Tethered chargers offer a range of significant convenience in that they are fixed, ready to go and do not require cumbersome user operations. This design not only reduces wear caused by frequent movement and improves durability, but also enhances anti-theft security due to the fixed nature of the cable. However, this convenience comes with some limitations. It is mainly reflected in the limitation of cable length, which undoubtedly restricts the use of the charger and makes it lack of flexibility. In addition, not all electric vehicles are compatible with tethered chargers, which may limit the options for some users. For those users who need to use charging services in different locations, fixed installation chargers are slightly less portable.

Tethered chargers can face challenges in terms of compatibility. Different electric vehicle and charging standards can cause connectivity issues. For example, the J1772 connector in the United States is suitable for single-phase power supply, while the CCS connector supports faster multiphase charging. Tesla uses a unique connector, but can be compatible with other standards via adapters. Cable length is also a consideration, traditional cable length is generally 5 to 8 meters, suitable for home use, but commercial environments or special parking situations may require different lengths of cable.

Untethered EV Chargers

Untethered electric vehicle chargers represent the flexibility of charging technology. These chargers are usually mounted on a wall or pedestal, and the user can select and connect the appropriate cable according to the need. Unlike tethered chargers, untethered chargers do not fix cables, allowing users to choose different lengths of cables according to actual needs. This charger is suitable for a variety of vehicles and charging situations because it offers a wide range of compatibility.

Untethered chargers are known for their versatility and portability, and they support a variety of cable types and lengths, giving users the flexibility to choose according to different charging needs and scenarios. The upgradability of this charger is also a significant advantage, and users can easily change the cable to adapt to the new charging standards, ensuring that the charger remains compatible and useful in the long term. In addition, the portability of the untethered charger makes it ideal for use in multiple locations, whether at home, office or public charging stations, providing a convenient charging solution.

However, untethered chargers also have some drawbacks. Each charge requires users to manually connect the cable, which can be inconvenient for some users. In addition, users are responsible for the storage and maintenance of the cables themselves, which increases the requirements for cable management. At the initial setup, users may also need to purchase additional cables, which involves additional costs. Nevertheless, the flexibility of the untethered charger remains its biggest selling point, allowing users to select and use cables according to their specific needs, providing a personalized charging experience.

The Main Considerations When Choosing a Charger

Personal Preferences and Usage Patterns

When choosing a tethered or untethered charger, you need to consider your daily EV usage. Do you value convenience or flexibility more? Do you need to adapt to different vehicle and charging situations?

Cost Comparison

In general, the initial purchase cost of untethered chargers is low. For example, non-tethered chargers can cost about $500, while tethered chargers can cost $600 or more. In addition, untethered chargers may require a separate cable purchase, which can add to the total cost.

Security and Anti-theft

Tethered chargers are usually equipped with cable locks, reducing the risk of cable theft. Untethered chargers require users to pay extra attention to the safe storage of cables, and can consider using a locking cable bag or security storage box.

Future Charging Solutions

Untethered chargers are popular because of their adaptability, allowing users to replace cables based on new models or changes in industry standards without having to replace the entire charger. While cables are not easy to replace, many modern devices are equipped with upgradeable features that maintain compatibility with new electric vehicles.

Conclusion

Choosing the right EV charging device is an important part of EV ownership. Tethered chargers and untethered chargers have advantages and disadvantages, and you need to choose according to your personal needs and charging environment. Understanding the features of these charging options can help you make more informed decisions and ensure your EV charging experience is smooth and hassle-free.
