As owner of a electric cars The question is what type of charging station is the most appropriate. Should you choose an AC or DC charging station? In this article, we'll explain the differences between charging stations and show you in which situations which type of charging station is best suited.
AC charging stations or private wallboxes: ideal for everyday use
AC charging stations, also known as normal charging stations, offer a charging speed of up to 22 kW and are ideal for everyday use, especially for commuters who charge their cars overnight. Such charging stations are often installed in private households, but they are also widely used in public places such as parking lots, shopping centers and hotels. AC charging stations are equipped with a Type 2 plug equipped, which is used in almost all electric cars.
DC charging stations or fast charging stations: For long distances and fast charging
DC charging stations, also known as fast charging stations, offer a higher charging speed of usually 50-240 kw and are ideal for long distances and fast charging. This type of charging station is often found on motorways and expressways and can charge the electric car to 80% or more in a short time. DC charging stations are equipped with a CCS- or CHAdeMO-Plugs equipped, which are used by almost all electric cars.
HPC: High Power Charging — even faster than fast?
HPC charging stations stand for high-power charging and are a variant of DC charging stations that offer an even higher charging speed of up to 350 kW. Compared to normal DC charging stations, however, they are much more expensive and require specialized infrastructure, which must be provided by energy providers. HPC charging stations are particularly useful for use on motorways or on long trips where fast charging is required.
Spoilt for choice: fast or normal charging?
Most would ask this question directly with “quickly, of course!” answer. However, it's important to note that fast charging at a DC charging station can affect battery life. The reason is that fast charging creates more heat, which can cause the battery to wear out faster. Experts therefore recommend charging electric cars at a DC charging station only when it is really necessary and otherwise using AC charging stations instead.
Another aspect that you should consider when deciding between AC and DC charging stations is the impact on the power grid. Fast charging stations, in particular DC charging stations, can cause consumption peaks, which can lead to problems in the power grid. For this reason, energy suppliers must upgrade and expand their networks accordingly to ensure that they can meet the increasing demand for electric mobility.
Availability of charging stations in Germany
When it comes to charging an electric car on the go, it is important to know which charging stations are available. There are now many public charging stations in Germany that offer both AC and DC charging. However, DC charging stations are not yet as widely used as AC charging stations because they are usually more expensive and require higher power. Private wallboxes are also a good option for those who want to charge at home or at work.
In Germany and Europe, there is a growing number of AC and DC charging stations in public places such as parking lots, shopping centers and motorways. Some supermarkets and shopping centers offer AC charging stations to attract customers. There is also a growing number of private AC charging stations being installed by companies and individuals.
Especially near motorways, there are mainly DC charging points.
Conclusion on e-car charging: Is it slow enough or does it have to be fast?
In summary, both AC and DC charging stations have their advantages and disadvantages. Which type of charging station is the best choice for you depends on your individual needs and the availability of the respective charging stations. If you have more time, it's best to look for a public AC charging station or charge your e-car at your private wallbox. In particular, if you charge your electric car overnight at home using a private wallbox, AC charging is completely sufficient. This not only relieves the power grid, but also prevents consumption peaks and protects your Akku.
It goes without saying that it makes more sense to use a DC or HPC charging station on long-haul trips. This allows you to charge your car and drive on within approx. 30 minutes. After all, you also want to get to your destination quickly.
