For each electric vehicle charging type, there are specific technical requirements. In somes cases, you may also need to increase the capacity of your installation, or even modify it thoroughly...
Different charging types
1. Normal charging
Normal charging (up to 7.4 kW) on a conventional connection (single-phase or three-phase) is perfectly suited to serve the overriding majority of vehicles and does not involve any adjustments to your electrical installation.
This makes it the cheapest and the easiest solution to put in place.
To give you some idea of the charging time required for your vehicle in consideration of the power of your charging point, run a simulation.
You will find that normal charging amply suffices for conventional vehicle usage (the average Belgian drives around 50 km a day, whilst a 6-hour charging time allows a small town car to stay on the road for anywhere from 100 to 200 km).
Please be aware that certain vehicle models require a specific connection (involving a neutral conductor), even when they are charged from a normal charging point.
2. Quick and semi-quick charging
Quick and semi-quick charging requires more power and specific connection configurations. As such, it is important that you discuss your needs with the charging point installation company if you decide on this kind of charging point.
In among other things, it is for the installation company to draw your attention to two kinds of limitations:
Quick and semi-quick charging requires you to be connected to a 400 V three-phase network with a neutral conductor.
However, the vast bulk of the Brussels power grid is a 230 V three-phase network without a neutral conductor. Which means there could be a compatibility issue.
How to resolve this problem? There are three potential solutions:
• Your installation company can fit a three-phase 230 V/400 V autotransformer in front of your charging point. This is the same technology that is used for a lot of lifts. If you are connected to the single-phase 230 V network, you will first need to apply for a three-phase 230 V connection with Sibelga.
• In some cases, depending on the set-up of the network where your home is located, Sibelga can supply you directly with three-phase 400 V + neutral conductor power. As a result, you may be required to make changes to your indoor installation (distribution board, wiring, etc.).
• Faced with these limitations and expenses, and after having assessed the charging time required for your kind of vehicle use*, this enables you to decide whether or not a normal charging installation is suitable for your situation. A normal charging installation will enable you to cover your everyday needs with smoothed overnight charging. Moreover, this solution remains the cheapest and the easiest to put in place.
If you decide to go for a more powerful charging point, it is likely that the power of your installation will need to be stepped up.
The power supplied by Sibelga will simultaneously need to cover the requirements of your charging point as well as your household needs (electrical appliances, kitchen, electric heating, lighting , etc.).
So do not forget to allow for a sufficiently large power margin when you submit your application with Sibelga for works to be carried out.
Before deciding on which kind of electric vehicle and the appropriate charging mode to go for, make sure you find out exactly what is what from your car dealership, your charging point installation company and Sibelga.
If you decide on quick or semi-quick charging, chances are you will need to make major alterations to your electrical installation at your own expense.
Please note! Not all electric vehicles are compatible with all types of charging points. Your car dealership will advise you on the various options open to you.
