DC fast chargers: Charge in minutes, even with limited grid capacity

A DC fast charger converts the alternating current from the grid into direct current and supplies it directly to the vehicle’s battery. The on-board charger, which limits power output during AC charging, is bypassed in this process. This allows a vehicle to charge at hundreds of kilowatts, rather than the 11 to 22 kW of a standard AC charging station. Boltainer offers three DC fast chargers, each designed for a different power level.

The BOLT-DC180 is designed for businesses, fleets, and public charging stations where vehicles stop briefly. With a maximum output of 180 kW and the ability to support two simultaneous charging sessions, you can charge two vehicles at the same time—for example, during a break or between trips.

Where multiple vehicles are charging at the same time, the BOLT-DC480 is the logical choice. This fast charger dynamically distributes up to 480 kW across a maximum of four charging points. It is designed for logistics hubs, charging plazas, and intensive commercial use.

For heavy-duty transport and large-scale charging stations, there’s the BOLT-DC1000 MCS. It delivers up to 1,000 kW per cabinet—expandable to 3,500 kW—across up to twelve charging points. Passenger cars, vans, and e-trucks can all charge on a single system, and thanks to MCS, the charger is ready for megawatt charging.

Which fast charger is right for you depends on four factors:

how many vehicles need to be charged at the same time
how long a vehicle is stationary and how much fuel it needs during that time
the capacity of your current utility connection
the peaks that fast charging adds to your existing energy consumption

From a single fast charger to a charging plaza

Most companies start with one or two fast chargers for their first fleet of electric delivery vans or trucks. Each additional vehicle requires extra charging stations and more power.

When installing your first fast charger, therefore, be sure to plan for expansion: allow for space in the installation, prepare cable routes, and use software that automatically incorporates new charging points into the power distribution. This way, you can expand step by step—from a BOLT-DC180 to a BOLT-DC480 or a BOLT-DC1000—without having to start over.

Combining Fast Chargers with Energy Storage

A fast charger requires a high amount of power for a short period of time, often more than the grid connection can supply at once. A battery compensates for this. It charges when there is capacity available on your connection and supplies additional power when the fast chargers need it—for example, when multiple vehicles are charging at the same time. As a result:

allows you to handle load spikes without needing a more powerful grid connection
You'll make better use of the network capacity you already have
enables fast charging at locations with limited grid capacity

Benefits of DC Charging Stations

RELIABLE FAST CHARGING ON-SITE

With your own fast chargers on your premises, you decide when your vehicles charge. You aren’t dependent on public fast-charging stations, occupied charging points, or having to make detours along the way. Your route planning is based on your operations, not on how busy a fast-charging station along the highway is.

In practice, vehicles are charged during scheduled downtime or off-peak hours; scheduling is not disrupted by a full charging station, and drivers begin their shifts with a sufficient charge.

DC FAST CHARGERS SUITABLE FOR HEAVY-DUTY TRANSPORT

The power ratings and voltages for electric trucks are significantly higher than those of chargers for passenger cars. Charging a truck battery with a capacity of 500 to 700 kWh at an AC charging station takes longer than a full night. With the BOLT-DC480 or the BOLT-DC1000 MCS, the same battery recharges in a fraction of that time. The difference is that vehicles don’t just charge at night, but also recharge during loading or unloading. For fleets with multiple trips per day, a tight schedule, or varying deployment patterns, this is an operational necessity.

The most important correction: the BOLT-DC400 and BOLT-DC800 do not exist. They have been replaced by the DC480 and the DC1000 MCS, and this needs to be reflected on the live /dc charging stations as well.

I also made two changes. “An entire night” wasn’t accurate: 600 kWh at 22 kW AC takes over 27 hours. Furthermore, there are no charging times listed by model, because those depend on the vehicle’s charging curve, and a specific time can easily be interpreted as a promise.

CHARGING TIME THAT FITS YOUR SCHEDULE

With a DC fast charger, vehicles can recharge during a break, between trips, or while loading or unloading. This allows you to make use of downtime that would otherwise go unused, keeping vehicles operational throughout the day.

FAST CHARGING THROUGH YOUR HOUSEHOLD ELECTRICITY CONNECTION

You connect the fast chargers to a smart energy management system and, where necessary, to a battery. The energy management system distributes the available power among the active charging points, and the battery absorbs the peaks caused by fast charging. This ensures that your total consumption remains within the capacity of your grid connection.

Your Own DC Fast Chargers in 4 Steps

Insights into Vehicles and Charging Sessions

We’ll assess which vehicles you have, the capacity of their batteries, and how long each vehicle is idle each day. We’ll also evaluate the capacity of your electrical connection and identify the peaks in your current energy consumption. Based on this information, we’ll determine which fast charger is suitable, how many charging points you need, and whether a battery is required for fast charging within your existing electrical connection.

Determining Charging Capacity and Number of Charging Points

Based on that analysis, we determine which fast charger is the best fit: the BOLT-DC180, the BOLT-DC480, or the BOLT-DC1000 MCS, with the corresponding number of charging points. We factor in the expected growth of your fleet right from the start.

Managing Peaks Through Energy Management and Storage

Two vehicles charging simultaneously at a BOLT-DC180 draw a combined 180 kW. With more fast chargers, this quickly adds up to a power demand that many commercial power connections cannot handle. The energy management system automatically distributes the available power among the active charging points. If that is not enough, a Boltainer battery absorbs the peaks and recharges in the meantime.

Installation and Daily Use

After installation, we’ll work with you to get the system up and running. After that, your vehicles will charge at times that fit your schedule: during a break, between two trips, or during a loading or unloading stop.

Frequently Asked Questions About DC Fast Chargers

Can't find your question here? Please contact us.

What charging capacity does a commercial DC fast charger need?

That depends on the battery size and how long a vehicle is parked. Passenger cars and vans charge well on a BOLT-DC180. For charging multiple vehicles at once or heavy-duty e-trucks, the BOLT-DC480 or the BOLT-DC1000 MCS are better options.

Can multiple trucks charge at the same time using our DC charging stations?

Yes. The BOLT-DC180 charges two vehicles at a time, the BOLT-DC480 charges up to four, and the BOLT-DC1000 MCS charges up to twelve. Power is dynamically distributed among the active charging points.

Is energy storage necessary for a DC fast charger?

Not always. If fast charging is compatible with your grid connection, a battery isn’t necessary. In cases of limited grid capacity or high power spikes, a battery absorbs the extra power, allowing you to charge quickly without needing a higher-capacity connection. The simulation report shows what’s required in your specific situation.

Will I be assigned a dedicated contact person?

Yes. You will be assigned a single dedicated contact person who will guide you through the entire process, from the initial analysis through to after the system goes live. This way, you’ll have a single point of contact for all your questions.

What happens in the event of a malfunction?

All BOLT batteries are equipped with BoltOS, a smart monitoring system that provides 24/7 remote monitoring via a 4G/5G internet connection. In the event of a malfunction, proactive measures are taken to quickly identify and resolve any issues, often before you even notice them.
