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? 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?
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. 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: Choosing an appropriate length of charging cable is essential. There are no standard guidelines around the best size of EV cables, but the recommended length is between 4m and 10m. That said, you can go for longer cables depending on your requirements. 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. Before diving into charging cable lengths and key considerations when deciding your charger cable length, you must understand the difference between tethered and untethered chargers.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. 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 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.
As an EV owner, you might have a lot of questions when it comes to buying an EV charging cable. Keep reading to find answers for all of them. How Long Can an EV Charging Cable Be? 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. 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 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. 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 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.
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. 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. 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.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
