When and how to use DC fast charging

Perhaps to illustrate the obvious – soonplus DC fast chargers are faster than level 2 AC charging stations. They’re also just as easy to use as an AC charger. As with any Level 2 charging station, just tap your phone or card, plug in to charge, and go on your merry way. The best time to use a DC fast charging station is when you need an immediate charge and are willing to pay a little more for the convenience – such as when you’re on a road trip or when your battery is running low but you’re pressed for time.

Check out these tips for a great DC fast charging experience.

Tip: Not every electric vehicle (EV) is compatible with DC fast charging stations. If you think you’ll need fast charging from time to time, be sure to ask about this option when shopping for an EV.

Check your connector type
DC fast charging requires a different type of connector than the J1772 connector used for Level 2 AC charging. Leading fast charging standards are SAE Combo (CCS1 in the US and CCS2 in Europe), CHAdeMO and Tesla, and GB/T in China. More and more EVs are coming with DC fast charging these days, but be sure to check your car’s ports before trying to plug it in.

The soonplus DC fast charger can charge any vehicle, but the North American CCS1 and European CCS2 connectors are best for the maximum amperage that is becoming the standard for new EVs. Tesla EV needs a CCS1 adapter to use soonplus for fast charging.

Here’s what some common connectors look like:
Tip: You can filter by connector type in the soonplus app to find the right charging station for your EV.

Save fast charging for emergencies
DC fast charging is generally more expensive than level 2 charging. Because they provide more power, DC fast charging stations are more expensive to install and operate. Station owners usually pass some of these costs on to drivers, so it really doesn’t make sense to use fast charging every day.

Another reason not to overcharge during DC fast charging: DC fast chargers generate a lot of power, and managing it can put extra stress on the battery. Using a DC charger all the time reduces the efficiency and lifespan of your battery, so it’s best to use fast charging only when needed. Keep in mind that drivers who cannot charge at home or at work may rely more on DC fast charging.

follow the 80% rule
Every EV battery follows a so-called “charging curve” as it charges. Charging begins slowly while your vehicle monitors the battery’s charge level, outside weather, and other factors. Charging then ramps up to peak speed for as long as possible, and slows down again when the battery is about 80 percent charged to preserve battery life. (Check out this post and this post to learn more about charging curves.)

When using a DC fast charger, it’s best to unplug the battery when it’s about 80% charged. That’s when the charging speed drops off dramatically. In fact, it takes almost as long to charge the last 20% as it takes to charge to 80%. Not only is it more efficient for you to unplug when you hit the 80% threshold, but it’s also considerate to other EV drivers, helping to ensure that available fast charging stations are available to as many people as possible. Check the soonplus app to know your charge status and know when to unplug.
