AC and DC charging: the difference

What is AC charging? And how does it compare to DC charging? These two methods form the basis of electric vehicle charging. In this blog, you will read more about them. We explain exactly what it is and what the differences are.

AC charging means 'Alternating Current' and is the most common form of electric charging for vehicles. It is also known as alternating current charging. AC charging uses the standard electrical connection found in homes and most businesses. The alternating current from the electricity grid is fed directly to the electric vehicle. There, a built-in inverter in the vehicle converts the alternating current into direct current to charge the battery. This method is mainly used for everyday use at home or at work.

DC charging is a faster way to charge electric vehicles. It is also known as DC charge and is useful during long trips where fast charging times are required. DC stands for 'Direct Current'. This involves direct current being fed directly to the vehicle's battery. This speeds up the charging process, think of roadside fast chargers or hotels.

What exactly is the difference between the charging modes and what does this mean for charging speed, installation and operating costs, availability and applicability?

Charging speed

• AC charging: has a relatively slower charging speed. This is usually up to a maximum of 22kW. Although most cars go up to a maximum of 11kW. This makes it more suitable for home use or in workplaces where your electric car can stand for long periods of time.
• DC charging: has a much higher capacity, from 50kW to 350kW or even more. This ensures the faster charging time that electric cars can reach 80% within 20 to 30 minutes

Installation and operating costs

• AC charging: requires less complex and cheaper installation. This makes it a cost-effective option for private homes and businesses.
• DC charging: DC charging involves higher installation and operating costs. This is due to the technology and infrastructure required to deliver this powerful energy.

Availability and comfort

• AC charging: is wide available and can be installed almost anywhere there is a standard electricity connection, including at home and at work.
• DC charging: is less widespread due to higher costs and is mainly installed in strategic locations such as along motorways and in (large) urban areas.

Appropriateness

• AC charging: suitable for everyday use where the car is parked for long periods of time, such as at home or in the office.
• DC charging: ideal for long trips or situations where quick recharging is needed.

AC and DC charging both have their benefits. If you are looking for a charging station for home or work, choosing a reliable AC solution is important. Want to know more about this? Then check out our website.
