Are you currently driving an electric vehicle (EV) or managing a fleet and looking for the optimal charging solution? The choice between Alternating Current (AC) and Direct Current (DC) charging is crucial for your business's charging infrastructure. Let's delve into the benefits and considerations of both AC and DC charging, so you can make an informed decision.
Getting started
We all know that electric vehicles are charged with electricity, but did you know there are different types? Electricity comes in two forms: Alternating Current (AC) and Direct Current (DC). In a nutshell, AC charging points charge EVs more slowly than DC charging points. But how does it work? And what is the best type of charging point for your business?
What is AC Charging?
AC charging, or Alternating Current charging, uses the same type of electricity that powers our homes and businesses. This electricity comes into your home from the socket. AC chargers are commonly found in households and commercial buildings, making them easy, accessible, and cost-effective to install.
AC charging points transfer electricity from the power grid to your electric vehicle via the charging cable. The built-in inverter in your EV converts this electricity from Alternating Current (AC) to Direct Current (DC) and stores it in the battery. The charging time depends on the type of charging point, your electricity connection, and the capacity of the inverter. In general, lighter inverters are slower than heavier ones.
The benefits of AC charging
Versatile and Compatible
AC chargers are compatible with most EV models. This versatility makes them a suitable choice, especially if you manage a mixed fleet of electric vehicles. Whether you oversee a small fleet or have a large and diverse range of EVs, AC charging can meet your needs.
Cost-effective installation
Compared to DC chargers, AC chargers have relatively lower installation costs. They can utilise existing electrical infrastructure, meaning if your business already has electric outlets or a three-phase power supply, setting up AC charging stations becomes easier and more affordable.
Slower, but sufficient charging
AC chargers typically deliver power in the range of 3,7 kW to 22 kW. While this may be slower than DC charging, it can still be ideal for overnight charging or during longer parking periods. If your company's vehicles are parked for a significant amount of time, AC charging can ensure that their batteries are sufficiently replenished.

What is DC charging
DC charging stations, or fast chargers, convert Alternating Current (AC) to Direct Current (DC) before the energy reaches your car, using their built-in inverters. This means powerful Direct Current (DC) flows directly from the charging station to your battery, resulting in a faster and more potent charging experience compared to AC charging. You often find these charging stations along highways, in busy urban areas, and within public charging networks.
The benefits of DC charging
Fast Charging
DC chargers supply power directly to the vehicle's battery, bypassing the onboard charger. This direct transfer enables charging speeds of 50 kW or more, significantly speeding up the charging process. If you aim to regularly and quickly charge your fleet, DC charging provides the necessary convenience.
Long-distance travel
For businesses with long-distance or delivery vehicles, strategically placed DC charging stations along key routes can facilitate efficient travel. With shorter charging stops, your drivers spend less time waiting and more time on the road, ultimately increasing productivity.
Future-proof investment
As technology advances, an increasing number of EV models are equipped with faster charging capabilities. By investing in DC charging, your company positions itself for future growth and ensures compatibility with upcoming EV models.
Load balancing
Similar to AC charging facilities, DC chargers can be equipped with hardware and software that provide dynamic load balancing. This means they utilise available power capacity. Does your building or location need more power for heating or air conditioning? The charging facilities adjust the charging current, and once more capacity becomes available, they automatically scale up.

How do you choose the right option?
Now that we've explored the benefits of both AC and DC charging, you're probably wondering: How do I choose the right option for my business? Do you opt for AC or DC charging points for your company, or a combination? Let's recap the key factors:
Assess your needs
Evaluate your company's charging requirements, including the average daily mileage, charging duration, and the number of vehicles in your fleet. This analysis helps determine whether the convenience of DC charging justifies the higher installation costs.
Balans between cost and speed
If your fleet primarily operates locally, AC charging may provide sufficient charging speeds while keeping installation costs low. On the other hand, if your business heavily relies on long-distance travel or requires fast charging to meet demanding schedules, investing in strategically placed DC charging stations may be worthwhile.
Future-proof
Considering the future of EV technology is essential. As more advanced EV models with faster charging capabilities enter the market, having DC charging infrastructure ensures that your company remains compatible and ready for the next generation of electric vehicles.
There is no one-size-fits-all solution for AC or DC charging. The key is to evaluate the unique needs of your business and find the right balance between cost and speed. By assessing factors such as average daily mileage, charging duration, and the main focus of your fleet, you can make an informed choice that aligns with your charging requirements.
