Charge electric vehicles in minutes with fast charging solutions for on-the-go locations.
One of the key barriers to EV adoption is range anxiety. With more DC fast chargers on the road, your business will be a catalyst in the electric mobility revolution.
DC charging charges your EV to 80 percent capacity at full speed and then reduces output to ensure it doesn’t affect the performance of your EV’s battery.
As more DC fast chargers are introduced to the public, EV drivers can integrate charging into their daily routines (e.g. charging whilst eating lunch or doing the groceries).
EV Just like their AC counterparts, DC fast charging stations are easy-to-use: just tap to pay, plug in, charge, and be on your way. for business are designed to be weatherproof, shockproof, and can withstand 24/7 charging.
Because you can charge on the go, you don’t have to worry about whether a single charge will be enough for your entire journey.
With power outputs between 90 kW and 400 kW, fast charging stations increase charging speeds dramatically.
There are two different types of EV charging stations: AC and DC. It's important to keep in mind that power from the grid is always AC and EV batteries only accept DC power. That means that at some stage, the current must be converted. The difference between AC and DC charging stations is whether that power convertor is located onboard or off-board the vehicle.
With DC charging, the convertor can be significantly larger due to the fact that it is located off-board the vehicle. Because the current is already converted to DC by the time it reaches the vehicle, it is possible to deliver more power, faster.
As a result of this different charging technique, DC stations can provide up to 350 kW of power and fully charge an EV in 15 minutes (providing the EV allows it). Due to their fast charging abilities, DC fast chargers are ideal for short-stop locations, fleet vehicle charging, and are beneficial for passenger vehicles as well as buses and trucks.

The kW output of DC fast charging stations varies depending on multiple factors including location, make, and model.
Broadly speaking, there are two different kinds of DC fast charging stations: standalone, and split.
At EVBox, we have fast chargers that span from 50 kW all the way to 350kW.

There are a number of factors which affect an EV’s charging speed with DC charging. However, because the AC/DC converter is located in the charging station itself, charging an electric vehicle with DC charging can be significantly faster than with AC charging.
Different factors which affect a vehicle’s charging speed with DC charging include the battery’s current charge, the weather conditions (batteries charge slower in the cold), the battery’s charging capabilities, and, of course, the power output.
Battery’s current charge: Due to measures to increase battery life and ensure safe charging, charging slows down significantly for the final 20 percent. As DC fast charging takes an EV's battery to 80 percent capacity in a comparatively short amount of time versus AC charging and then slows down for the remaining 20 percent, the time it takes for your battery to reach 100 percent full may be the same for the initial 80 percent charge.
Weather conditions: Depending on where you are charging your EV, the temperature may effect the charging speed. Cold temperatures can negatively impact charging speeds due to the fact that lithium-ion batteries—those used to power EVs—are very sensitive in low temperatures.
Power output: Obviously, the power output of the charger will have an effect on charging times. For example, 15 minutes of charging time can give you between 130 km and 480 km additional range at 100 kW and 350 kW output respectively. At 50 kW, one hour of charging a passenger vehicle will add an additional 278 km of range.
Additionally, we always say that the car is the “master” when it comes to dictating charging times. Some vehicles can accept more power than others. For example, while a Tesla Model 3 can accept 250 kW, a Nissan Leaf can only accept about 50 kW.

DC charging works with the vast majority of passenger vehicles. By default, EVs charge their batteries with direct current and this means that almost all accept DC fast charging. How much power each battery can handle, however, is another story. Some batteries can accept 350 kW whilst others can only accept 50 kW. Additionally, a very small portion of electric vehicles with smaller batteries do not have the capacity to charge with DC charging—for example, the Fiat 500 does not offer a fast charging capability. To get the most out of DC fast charging, it’s important to consider whether the EV supports DC charging, and if so, what is the maximum output that it accepts?
Whilst almost all passenger vehicles can use DC fast charging, the process of charging itself may require a different connector than the one your vehicle uses with AC charging.
Looking at the European level, there are two standards for DC charging connectors—CCS and CHAdeMO—as well as Tesla’s signature Supercharger which you have to consider.
Combined Charging System (CCS) allows for both AC and DC charging through the same input port, while vehicles equipped with CHAdeMO have a separate port for AC charging and can’t charge faster than 50 kW.
Due to this shortfall, CCS is becoming the dominant standard across Europe and North America and CHAdeMO is getting phased out across both continents.
While there are still over half a million vehicles with CHAdeMO plugs on the road in Europe, Europe recently announced that CCS2 will become the standard.
That means that a CCS connector is likely to be necessary for DC fast charging in the future—at least in North America and Europe.
It is most likely that DC fast charging does cost more than charging your electric vehicle with AC power. When you’re paying for DC charging, you’re paying extra for the convenience of charging your vehicle quickly.
The price difference, however, depends on the location in which you charge and whether the charging station bills by the minute or by kWh.
Balancing price and convenience comes down to knowing what’s best for your vehicle. For instance, if your vehicle's maximum DC charging capability is 50 kW and you're occupying the ultra-fast charging station (250 kW), then you're going to be paying more whilst still receiving the same charge.
Ultimately, the answer is yes, DC fast charging costs more than AC charging, but it’s important to ask yourself, “Do I actually need to charge this fast or is it more logical to charge slower?”
DC fast charging stations are ideal for commercial and public locations, meaning that you’re likely to find them at retail and hospitality locations, in commercial parking stations, fuel retailers, highway rest stops, and utility providers.
To find a DC fast charger, Google Maps is a great option or you can always open up the EVBox Charge app.
