EV chargers

A charging point draws a lot of power. Without load management, running the dishwasher, the oven and the car at the same time trips the main fuse.

We first look at your connection and your current consumption, then install the necessary protection and controls. That way the car automatically charges more slowly when the rest of the house needs a lot of power.

Also for small businesses with a few charging points in the parking lot.

What we take care of

Wall-mounted or pedestal charger on the outside wall, in the garage or by the driveway
Single-phase to three-phase, from 3.7 to 22 kW
Dynamic load balancing, so your main fuse can cope
Tethered cable or untethered socket, as you prefer
Cable route to the electrical panel, including under the driveway
Charging on your own solar power
Inspection of the charging point
Charging points for staff or visitors at businesses

What output do you really need?

A car that's plugged in for twelve hours overnight has plenty with 7.4 kW: that's good for about three hundred kilometers of range between dinner and the morning.

Eleven or twenty-two kilowatts only makes sense if you have a three-phase connection and the car can handle that output. Many models don't charge faster than 11 kW on alternating current, however powerful the charger. We check that before we put an output on the quote.

DC rapid charging, like along the highway, isn't a realistic option at home: it requires a connection of a completely different order.

Load balancing: why your fuse won't trip

A charger at full power draws as much as an oven, a stovetop and a dryer combined. Switch them all on at once and the main fuse trips.

With dynamic load balancing, a sensor at the meter measures how much the rest of the house is using at that moment, and the charger adjusts its output accordingly. When you're cooking, the car charges a little more slowly; when the stovetop goes off, it picks up again.

That way you don't need to upgrade your connection, which means an application to the grid operator and a considerable cost.

Charging on your own sunshine

If there's already an inverter from the same range, the charger can use whatever your roof has spare at that moment. The car then becomes the biggest user of your own surplus, which usually pays more than exporting it.

You choose how strict that is: only on surplus, or always charging with the sun as a bonus when it shines.

The charger

A fixed charger charges faster and more safely than an outlet, and can work together with the rest of your home. Paired with your inverter, the car charges preferably on the surplus from your own panels rather than from the grid in the evening. With a tethered cable or an untethered socket, depending on where the car is parked and which plug it has. We choose that together when preparing the quote.

We are not tied to one brand. What we propose depends on your installation, your consumption and your budget. What you see above is always one of the options.

What the installation is made of

Connection and inspection

A charging point gets its own circuit with the right protection, and is included in the single-line diagram of your installation.

The installation is inspected. If your employer or leasing company asks for a certificate for the charging point, we make sure you have the right paperwork.

Frequently asked questions: EV chargers

Can my electrical installation handle an 11 kW charger?

Eleven kilowatts needs a three-phase connection. If you don't have one, 7.4 kW single-phase is the maximum, and that is more than enough for overnight charging. We check your connection and main fuse before putting an output on the quote, so you don't pay for a charger your installation can't supply.

Do I need to upgrade my connection for a charger?

Usually not. With dynamic load balancing, a sensor at the meter measures how much the rest of the house is using, and the charger adjusts its output accordingly. When you're cooking, the car charges more slowly for a while. That keeps you within your main fuse and avoids an expensive application to the grid operator.

How long does it take to charge my car at home?

At 7.4 kW you add roughly forty kilometers of range per hour. A car plugged in for twelve hours overnight is therefore well charged by the morning, even if it arrived almost empty. Faster charging rarely makes sense at home: the car is parked there anyway.

Can I charge on my own solar panels?

Yes, if the charger and the inverter talk to each other. The charger then uses whatever your roof has spare at that moment. You choose how strict that is: only on surplus, or always charging with the sun as a bonus when it shines.

Tethered cable or an untethered socket?

A tethered cable is more convenient day to day: you don't have to take anything out of the trunk. An untethered socket is more flexible if several cars with different plugs charge there, and the cable doesn't hang outside in all weather. We put both on the quote.
