How quickly you can charge at your home charger depends on a number of factors.
The type of car
Not every car charges at the same speed. If you are going to charge a slowly charging car with a fast charging station, the car is the limiting factor. The other way around is also possible. If your car can charge very quickly, but the charging station cannot deliver that charging capacity, the charging speed will remain low.
To find out the charging capacity of your car, it is best to contact the manufacturer of the car. You can usually find this information on their website.
The capacity of your electrical installation
You also need to know how your home is connected to the power grid. This can be done with a 1-phase connection or a 3-phase connection.
You can see which connection you have on the electricity meter in your meter cupboard.
You can also find it on the annual statement from your energy supplier.
A higher maximum charging capacity is possible with a 3-phase connection.
In many cases, houses with a single-phase connection can be retrofitted with a 3-phase connection. Please contact your grid operator if you wish to do so.
Please note: in Belgium, there are 3-phase connections without a neutral conductor. These connections have the same charging capacities as a single-phase connection.
Type of cable you are using
Our Blossom charging stations always have a type 2 connection where you can charge at a maximum of 32A. With a charging point with a fixed cable, you can charge at a maximum of 7.4 kW on a single-phase connection and a maximum of 11 kW on a 3-phase connection.
At a charging point with a socket where you use the cable that came with your car, it is good to know whether it is a 3-phase cable so that you can always handle the maximum power: when using a single-phase type 2 cable at a 3-phase charging point, you will be able to charge a maximum of 7.4 kW instead of 11 kW.
You can recognize a single-phase cable by the 2 "empty" pins at "L2" and "L3", where there are no connected cables.
A single-phase cable is also lighter and more flexible due to the absence of 2 phases.
Table with theoretical maximum charging capacities
Type of connection of the home to the electricity grid | Maximum charging capacity in kilowatts | Number of kilometers that you can charge per hour on average |
1 x 16A single phase (230V) | 3.7 kW | 22 km |
1 x 25A single phase (230V) | 5.8 kW | 35 km |
1 x 32A single phase (230V) | 7.2 kW | 43 km |
3-phase without neutralizer 16A (230V) | 3.7 kW | 22 km |
3-phase without neutralizer 25A (230V) | 5.8 kW | 35 km |
3-phase without neutralizer 32A (230V) | 7.2 kW | 43 km |
3-phase with neutral 16A (400V) | 11.0 kW | 66 km |
3-phase with neutral 25A (400V) | 17.2 kW | 103 km |
3-phase with neutral 32A (400V) | 22 kW | 132 km |
