DC Rapid Chargers

ElectrAssure offers a range of DC rapid chargers. These DC charging stations are designed to charge your Electric Vehicles fast and efficiently.

Why Use a DC Rapid Charger?

The main reason to use a DC charger is to recharge depleted vehciles rapidly. DC rapid charging is essential for EV fleets, eHGV and eBus operations. Stationary fleet vehicles waiting to charge reduces time in operation. Our DC rapid chargers paired with our maintenance plans are designed to maximise charger availability/uptime. The goal is to maximise revenue making operations of the vehicles on the road.

DC rapid chargers are categorised as Level 3 EV charging. This is the most powerful type of EV charging available. Typical DC charging power is around 15kW-400kW depending on the type of EV you are charging. 

How Fast Is DC Charging

Level 3 DC rapid chargers have various power outputs which can influence charging speed. However, here is an estimate for how many miles of range a DC charger can deliver within just a 60 minute charging period.

  • 30 Kw – 87 miles/hour
  • 50kW – 145 miles/hour
  • 100kW – 289 miles/hour
  • 120 kW – 347 miles/hour
  • 150 kW – 434 miles/hour
  • 180kW – 520 miles/hour
  • 250 kW – 723 miles/hour
  • 350 kW – 1012 miles/hour


Our DC Rapid Charging Stations

DC chargers can add between 65-600 miles range to typical electric cars/vans/HGVs and e buses for every hour that they charge. DC chargers are ideal for supporting Operational Fleets where a high level of availability is required for the driver or the vehicles to be charged.

In addition to load management and RFID/App/Contactless access control, ElectrAssure’s preferred Rapid Chargers provide fault tolerance and resilience features to ensure very high levels of charger availability.

How Does DC charging work?

How Does DC charging work?

There are two types do EV charging stations, AC and DC. The core difference between AC and DC chargers is whether the power converter is onboard or offboard the Electric Vehicle. The DC charger has a larger converter as it is located offboard the vehicle, this means DC chargers can deliver more power quickly. This offers EV vehicles full charge as quickly as just 15 minutes (as long as the EV power acceptance allows it). This makes DC charging stations perfect for fleet vehicle charging in short-stop locations. DC chargers are also the perfect choice for EV buses and trucks. 

DC charging FAQ

How does DC charging work?

DC charging allows energy to recharge the vehicle battery at an accelerated rate, due to not needing a small onboard AC to DC converter in the vehicle. The Battery cells in the vehicle charge & dissipate through DC, whereas the main electrical grid supplying EV chargers is AC. With DC converting the AC within the unit itself, it can house a larger converter, thus deliver more units of energy to the vehicle in a given time compared to AC charging.

How many kW is a DC charger?

DC chargers KW output can vary from 20KW to 1,000KW. Most use cases are for 60-180KW for cars/vans, and 120-450KW for eHGV/eTruck/eBus.

Is a DC charger better than an AC charger?

A DC Charger is usually found to have a higher energy output per unit of time, and thus reduces the time required to charge. It really depends on the application use case of what is best for your Fleet.

What’s the best DC charger for my business?

The best DC charger is: one that comes with high availability through reliability, spares available in your region, supported by your service provider for ongoing operations & maintenance, charges your critical fleet in the time allocated to charging & is compatible with your chosen CPMS provider.
