Choosing the right electric vehicle (EV) charger for your home can significantly impact your daily charging routine. Two primary options exist: tethered and untethered chargers. Each offers unique advantages and disadvantages, and understanding these differences is crucial for making an informed decision. This guide aims to provide a comprehensive comparison, helping you select the charger that best suits your needs.
What are Tethered EV Chargers?
A tethered EV charger comes with an integrated charging cable permanently attached to the unit. This design offers unparalleled convenience as the cable is always readily available. Imagine arriving home after a long day; with a tethered charger, you simply plug in and start charging without needing to retrieve a cable from your boot. This ease of use is particularly beneficial in adverse weather conditions, such as heavy rain or snow, when fumbling with a separate cable can be inconvenient.
However, this convenience comes with certain trade-offs. The fixed cable can limit flexibility, especially if you switch to an EV with a different charging port type in the future. For example, if you currently own an EV with a Type 2 connector and later switch to one requiring a CCS connector, you may need to replace the entire charger. Furthermore, the permanently attached cable can impact the aesthetic appeal of your home, as it remains visible when not in use. Because the cable is attached, there is a lower risk of cable theft. However, due to the cable being permanently attached, it is also permanently exposed to the elements, which can lead to faster wear and tear.
What are Untethered EV Chargers?
In contrast, an untethered EV charger is essentially a socket on your wall. You supply your charging cable, which plugs into the charger and your vehicle. This design offers greater flexibility as you can use any compatible cable. This is particularly advantageous if multiple EVs with different charging ports are used in your household. If you change your vehicle, you simply purchase a new cable rather than replacing the entire charger. The flexibility of untethered chargers extends to public charging, as you can use your cable at various charging stations. The ability to change cables also helps to future-proof your home charging setup.
Untethered chargers also offer a cleaner aesthetic, as there is no cable protruding from the unit when not in use. However, the need to store and retrieve the cable can be less convenient than a tethered option. Storing a wet or muddy cable in your boot can also be less than ideal. Because the cable is removable, there is a higher risk of cable theft.
Tethered vs. Untethered: Key Differences in Practical Use
