Are you currently driving an electric vehicle (EV) or overseeing a fleet and in search of the optimal charging solution? The choice between AC and DC charging holds significant importance for your organisation’s charging infrastructure.
We all know electric vehicles are charged with electricity, but there are different types. Electricity comes in two forms: Alternating Current (AC) and Direct Current (DC). In a nutshell, AC chargers charge EVs slower than DC chargers. But how do they work? And what is the best type of charger for your business?
Let’s dive into the benefits and considerations of both AC and DC charging, empowering you to make an informed decision.
Understanding AC Charging
AC charging, which stands for Alternating Current charging, uses the same type of electricity that powers our homes and businesses. You’ll commonly find AC chargers in households and commercial buildings, making them easily accessible and cost-effective to install.
AC chargers transfer electricity from the mains to your electric vehicle through the charging cable. Your EV has a built-in inverter that changes this electricity from one form (alternating current – AC) to another (direct current – DC), storing it in the battery. The time it takes for this conversion depends on the type of charger, your electricity connection, and the capacity of the inverter. Generally, lighter inverters are slower compared to heavier ones.
Here’s why AC charging might be the right choice for your organisation:
- Flexibility and Compatibility
AC chargers are compatible with most EV models available today. This versatility makes them a suitable choice, especially if you have a mixed fleet of electric vehicles. Whether you manage a small fleet or have a diverse range of EVs, AC charging can meet your needs effectively. - Cost-effective Installation
Compared to DC chargers, AC chargers have relatively lower installation costs. They can make use of existing electrical infrastructure, which means if your organisation already has electrical outlets or a three-phase power supply, setting up AC charging stations becomes easier and more affordable. - Slower but Sufficient Charging
AC chargers typically provide power in the range of 3.7 kW to 22 kW. While this might be slower than DC charging, it can still be ideal for overnight charging or longer periods of parking. If your organisation’s vehicles spend a significant amount of time parked, AC charging can ensure their batteries are adequately replenished.

Exploring DC Charging
DC charging, or Direct Current charging, offers a faster and more powerful charging experience compared to AC charging. You’ll commonly find these charging stations along highways, in busy urban areas, and within public charging networks.
Fast chargers or DC chargers work differently from regular AC chargers. Unlike AC chargers that rely on your EV’s inverter to convert electricity, fast chargers have their own built-in inverter. This means that the charge itself delivers direct current (DC) straight to your EV’s battery through the charging cable. This direct supply of current makes charging faster and more efficient.
Consider the following factors when deciding if DC charging is the right fit for your organisation:
- High-speed Charging
DC chargers deliver power directly to the vehicle’s battery, bypassing the onboard charger. This direct transfer enables charging speeds of 50 kW or more, significantly reducing charging times. If your fleet requires frequent and rapid charging, DC charging provides the necessary convenience. - Long-distance Travel
For companies with long-haul or delivery vehicles, strategically located DC charging stations along major routes can facilitate efficient travel. With shorter charging stops, your drivers can spend less time waiting and more time on the road, ultimately boosting productivity. - Investment for the Future
As technology progresses, more EV models are being equipped with faster-charging capabilities. Investing in DC charging infrastructure positions your organisation for future growth and ensures compatibility with upcoming EV models.

The Right Charger, The Right Place
Now that we’ve explored the benefits of both AC and DC charging, how do you choose the right option for your organisation? Will you opt for AC or DC charger for your business? Or a combination? Consider the following factors:
- Evaluate Your Needs
Assess your organisation’s charging requirements, including the average daily mileage, charging duration, and the number of vehicles in your fleet. This analysis will help you determine if the convenience of DC charging outweighs the higher installation costs. - Balance Cost and Speed
If your fleet primarily operates locally, AC charging may offer sufficient charging speeds while keeping installation costs down. On the other hand, if your business heavily relies on long-distance travel, investing in a few strategically placed DC charging stations might be a worthwhile expense.
When it comes to AC or DC charging, there’s no one-size-fits-all solution. The decision should be based on your organisation’s specific requirements and long-term goals. By understanding the benefits and considerations of both options, you can make an informed choice that maximizes efficiency and supports your EV charging needs.
Remember, the key is to evaluate your organisation’s unique needs and find the right balance between cost and speed. If your fleet primarily operates within a local area and you have existing electrical infrastructure, AC charging can be a cost-effective and practical solution. It may not be as fast as DC charging, but it can still meet the charging requirements of your vehicles during overnight stays or extended periods of parking.
On the other hand, if your organisation relies heavily on long-distance travel or requires rapid charging to keep up with demanding schedules, investing in DC charging infrastructure can provide the speed and convenience your fleet needs. With high-speed charging capabilities and the ability to reduce charging times significantly, DC charging stations are ideal for drivers who can’t afford to spend too much time waiting for their vehicles to charge.
It’s also worth considering the future of EV technology. As more advanced EV models with faster-charging capabilities are introduced to the market, having DC charging infrastructure in place will ensure that your organisation remains compatible and ready for the next generation of electric vehicles.
Ultimately, the decision between AC and DC charging should be based on careful consideration of your organisation’s unique requirements, budget, and long-term goals. By evaluating factors such as average daily mileage, charging duration, and the nature of your fleet, you can make an informed choice that aligns with your charging needs.
