Therefore, if you have an extremely long CCS charger, it may still charge faster than an extremely short Type 1 AC charger. Max. Charge Rate of the Vehicle and Connectors As humans, we need speed, convenience, comfort, and performance all at once. You might want a cable that charges your EV over a long distance in less time. Sadly, it isn’t possible. Science comes into the picture. Long charging cables have upsides and downsides. You’ll need to balance them based on your needs and make the right choice. Let’s look at the pros and cons of long charging cables. Benefits: There is no hard-and-fast rule for choosing the length of charging cables. They can be as long as someone wants. However, the longest EV charging cable available in the UK is 20 metres. In the US, the maximum allowed length for EV cables is 25 ft. Do longer charging cables take longer to charge?

What if you have already bought a fast charging cable? EV cables are expensive, and buying a new cable just because the previous one is short may not be the best decision. The good news is that you can extend your EV cable using an additional charging cable. Please note that length is not the only criteria to consider when selecting an EV cable. Several other factors must also be considered before making the final decision. You can follow this ultimate guide to buying charging cables for electric vehicles. How Does Length Affect Charging Performance? The type of charger is inarguably the most crucial factor that influences charging speed. Electric vehicle chargers are broadly classified into two types: AC charging cables and DC charging cables. Long electric car charging cables mean more convenience. You can charge your EV in your house or at public charging stations without worrying about the distance between your car and the charging point. So, how long can an EV charging cable be? Is a long charging cable always suitable? Long USB-C cables that come with a carrying wrap like the Anker Powerline+ are ideal for travel, but when you're looking for a long cable to snake from the wall plug to your bed, you'll want the rugged reliability of Uni's Type-C Charging Cable, which also has the benefit of coming in a 15-foot option if you need the absolute longest cable you can without giving up charging speeds.A long charger cable is beneficial, as you can park your EV away from the charging point and still charge it. A long tethered cable can help you save on installation costs, as you can install the EV charging station closer to the service panel. Overall, a long extension cable means more operational flexibility. Ideal Length of Electric Car Charging Cables When electricity flows through wires, it experiences some resistance (opposition to the flow of electric current). The higher the resistance, the lower the flow of current, resulting in a lower charging speed. Extension cords come in various lengths and specifications, and you can choose the one that best fits your needs. You can extend all EV cables, including three-pin and tethered cables. If your car supports 7 kW charging only, it won’t charge any faster than 7 kW even if you use 22 kW adapters. The cable length might end up being pointless if your EV has a low charge rate. Battery Size and Fullness Length is an essential factor to consider before buying an electric car charging cable. A longer cable provides comfort, convenience, and easy charging. However, you might end up losing some charging speed. Longer cables take more time to charge, and that is an adjustment you will need to make if you choose a longer cable.

A member of the XDA Developers forum performed an experiment to prove the relationship between cable length and charging speed. They took three cables of sizes 12″, 36″, and 72″. The experiment concluded that the 12″ cable charged 1.3x faster than the 36″ cable, while the 36″ cable charged 1.7x faster than the 72″ cable. On average, there was a 1.5x reduction in charging speed when the length of the cable was doubled. The output was the same for each cable. This is another cable that can support up to 100W charging, and while you probably haven't heard of Uni before, they make some excellent USB-C adapters, cables, and hubs that will last years and can take a beating. Another benefit to Uni's cables is that it comes in a 15-foot length, which is great if you need to run a cable across your entire room. The best long USB-C cables will serve you for years to come However, you must ensure that the additional cable has a power rating equal to or more than your primary connector. If you use a charger with a lower power rating, the overall charging speed may decrease. Another concern for EV owners is whether an extension cord reduces charging speed. The answer is no. The final charge speed will be the same as your initial charge speed. So, if your charger has a 7.2 kW output, it will remain the same.Therefore, it’s established that long charging cables take longer to charge than short charging cables. If you plan to get a long EV cable, your electric car will take a few extra minutes to charge. Can You Extend an EV Charging Cable? Environmental factors also affect charging speed. An EV takes slightly longer to charge in colder climates compared to hotter regions. This effect is more noticeable when you use public charging stations with rapid chargers. Conclusion While the length plays a vital role in the charging speed of an EV cable, it isn’t the only factor. Several other factors collectively act to determine the power output, and thus, the charging speed. Let’s briefly discuss some other factors that influence the charging speed of electric cars. Type of Charger Long cables are difficult to maintain. They are heavy, and therefore, challenging to carry and store. Since they’re long, they are more likely to tangle, giving you a hard time.
