Charge your E-car at home faster? Boost your mains connection

Posted on
Charging an electric car at home takes several hours. Does it have to go faster or do you need the power to run the dishwasher at the same time? Then consider having your mains connection boosted.

Busy days: we all have them. After a long day at work, you come home, cook some pasta, charge the electric car, and quickly wash your daughter’s hockey shirt. But what if it’s not possible to do all of that at the same time?

Not enough power

A charging point for an electric car consumes more electricity than any other household appliance. If the house’s electrical system is limited or outdated, it can take a very long time to recharge the car battery. “Plus, you have to have the necessary amps left over to use other appliances during the charging process,” adds Gerry Van Aken of charging service provider Eneco eMobility. “Otherwise, the fuses will blow as soon as you turn on the coffeemaker, for example. Or your charging station stops working and you can’t use your car if you want to go to the gym in the evening. If your home doesn’t get enough power to easily combine electric charging with household appliances, you can boost your mains connection.”

What does boosting entail?

If you boost your mains connection, the electrical capacity in your house will increase. For example, a house with a 1x25A connection (230 volts) is supplied with 25 amps of power via a single cable. Switching to a 3x25A connection and 400 volts provides three times as much power. Most Belgian homes have a connection value of 1x25A/230V, 1x35A/230V, 3x25A/400V, or 3x35A/400V. Substantial connection values, such as 3x63A/400V, are rare in private homes.

When is boosting useful?

Having your mains connection boosted is especially useful if you need more power than you get when charging your electric car. “In order for your household to function smoothly, you should have at least ten amps left,” says Gerry Van Aken. “Do you have a 1x35A connection and does your electric car use 32 amps to charge its battery, like a Jaguar I-PACE? Then you can boost your mains connection. If you drive a Tesla, you’ll need a 3-phase connection anyway to charge your car efficiently. Charging with a 1x25A or 1x35A connection will be very slow. Anyone who orders an electric (company) car with a charging point from Athlon can already rely on Eneco eMobility for support during the installation.”  


Even those who can easily combine their household usage with an electric car can consider boosting their mains connection. After all, our homes will need more and more power in the future. According to Gerry Van Aken, “If you want to install a heat pump or an air conditioner within a few years, a boosted mains connection will ensure that your household appliances continue to function properly. Electric car batteries are also becoming increasingly more powerful. So, boosting the electrical capacity of your home is a future-proof decision.”
