AC chargers come in two types: type 1 and type 2. Type 1 chargers are single-phase only and have a power rating of 3.7-7 kW. They can add 12.5-25 miles per hour. In contrast, Type 2 chargers support three-phase power and have a power rating of up to 22 kW. They can add up to 75 miles per hour. Some three-phase cable chargers support over 40 kW power rating, giving over 100 miles of charge per hour. 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. 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. 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? 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.

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. 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. Shop Type 2 Extension Cables from EV Cable Shop. Frequently Asked Questions How long can an EV charging cable be? 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? Frequently asked questions about charging cables 1. What is the difference between a Type 1 and Type 2 charging connector?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 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. 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? 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.

The second type of charger is DC chargers or rapid chargers. They are faster than AC chargers. They come in two types. The first is CHAdeMo, which has a 50-100 kW power rating and can add 75-150 miles per hour. The second is CCS, which has a power rating of up to 350 kW and can add up to 525 miles per hour. The larger the battery, the longer it will take to charge. An electric car with a 60 kW battery will take more time to charge than a car with a 40 kW battery, provided that you use the same charger. Also, if your battery is nearly full, it will fully charge in less time than an almost empty battery. Environmental Factors 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: 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 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

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?

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. 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. Long cables are convenient. You can park your car far away from the charging station and still charge it comfortably. Thus, long cables are ideal for outdoor use, especially if you charge your vehicle in public areas.Type 1 and Type 2 connectors are different plugs on the end of the charger cable attached to an electric car. For most electric vehicles produced in the UK from 2018 onwards, the type 2 EV charging plug is the most commonly used. 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 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
