When do you upgrade the fuse box for your charging station?

A charging station requires a lot of power. To prevent the fuses from blowing, it's necessary to give your fuse box an upgrade. In this article, we'll explain what this means and how you can do it.

What does upgrading mean?

When you give your fuse box an upgrade, it means that you increase the size of the gas or electricity connection. As a result, your fuse box will have more power. For example, you can go from a 1-phase to a 3-phase connector. Or, you can increase a phase connector, so it has more ampere. Your fuse box will be able to handle more large appliances at the same time, like a charging station, air conditioner, or induction cooktop.

Why upgrade?

Do you choose a charging station? There are 2 reasons why it's useful to upgrade your fuse box.

  1. You need more power to charge your car, especially if you want to use your TV or washing machine at the same time. By giving your fuse box an upgrade, you prevent the fuses from blowing. Thanks to this, you can do your laundry while you charge your car.
  2. You can charge the car faster with more power. Let's say your car can charge with a 3-phase connector but your fuse box has a 1-phase connector. Your car will charge slowly, because you don't have the power. With a 3-phase connector, this will go a lot faster.

Connector and charging capacity

The more charging capacity you have, the faster an electric car charges. This charging capacity depends on the connector and current of your fuse box. If you car can charge a maximum of 3.7kW, a 1-phase connector with 16 ampere is enough. Do you want to charge with 11kW? You need a 3-phase connector with 25 ampere.

Maximum charging capacity

Fuse box connector Maximum charging capacity fuse box
1x 16A 3.7kW
1x 25A 5.8kW
1x 35A 6.9kW
3x 16A 11kW
3x 25A 17.2kW
3x 35A 24.2kW
