Quick checklist: what you need before choosing a charging station

• Connection type: single-phase or three-phase (check your fuse box or energy supplier).
• Max. car charging speed: your EV also determines whether 11kW/22kW makes sense.
• Charging location: wall (wallbox) or post on the driveway; cable length and cable route.
• Smart charging: do you want to schedule charging during off-peak hours or link it to energy prices / solar panels?
• Safety: residual current device/circuit breaker and (if necessary) DC residual current protection in or next to the charger.
• Load balancing: useful with limited fuse box capacity or if you use many appliances at the same time.

Single-phase vs. three-phase: what is the difference?

In short: three-phase can deliver more power than single-phase. As a result, you can (usually) charge faster, provided your car and installation support it.

• Single-phase charging is often perfectly fine if you mainly charge at night and do not need maximum speed.
• Three-phase charging is popular for 11kW and higher, and provides more “room” for future use.

Note: whether you have three-phase (or can get it) varies by home. If in doubt, have an installer take a look.

11kW vs. 22kW: which is right for you?

The most popular home solution is 11kW. 22kW can be interesting if your installation and car can handle it and you want to charge faster.

Practical advice: if you mainly charge at night, 11kW is usually more than enough. If you drive a lot and want to “refuel” faster at home, 22kW can be interesting—but always check your EV specifications and fuse box.

Load balancing: when is it necessary?

Load balancing (dynamic power management) ensures that your charging station automatically uses less power when your household demands a lot of electricity (e.g., cooking, heat pump, washing machine). This prevents overloading and outages.

• You have a limited main fuse or you want to “be sure” that everything remains stable.
• You often use multiple high-power appliances at the same time (induction, heat pump, sauna, etc.).
• You want to expand in the future (extra EV, heat pump, home battery).

Installation & fuse box: what you need to know

A charging station is a powerful electrical device. A safe installation is essential. Think about the right circuit breaker/residual current device and the correct cable thickness suitable for the distance and power.

• Fuse box check: is there room for extra circuits and protection?
• Cable route: the longer the distance, the more important the right cable choice.
• Indoor or outdoor: choose a charging station with a suitable IP rating and sturdy mounting.

Tip: have the installation carried out by a certified installer and follow the applicable standards and guidelines.

Costs & smart saving tips

The total costs depend mainly on the charging station type, installation work (distance, excavation, fuse box modifications) and extras such as load balancing.

• Choose the right kW: avoid overkill if 11kW is sufficient.
• Plan smart charging: charging during off-peak hours or at low rates can reduce your costs (depending on your energy contract).
• Consider solar panel integration: smart charging can help you use more of your own generated electricity (depending on your setup).

Common mistakes (and how to avoid them)

1. Choosing based on kW alone: your EV and fuse box determine what you can actually achieve.
2. Not considering the future: an extra EV or heat pump? Think ahead now.
3. Cable too short: measure your driveway/parking realistically (also in the dark and in the rain).
4. No load balancing when in doubt: can prevent outages or power failures.
