Towing a trailer or caravan with an EV

Many electric cars can tow a trailer or a caravan. But the range drops a lot, and it can be hard to charge with the caravan attached.

What may the car tow?

Check the car's registration certificate (registreringsattest) to see how much it may tow. Some electric cars may tow 1,500 kg or more, some only 750 kg, and some nothing at all. A category B driving licence covers car and trailer up to 3,500 kg combined. If it is more, you need an extended licence.

The range drops

A caravan is big and heavy, and air resistance matters most. Consumption can easily become almost twice as high as without it. A low trailer costs less. Keep your speed down. With a trailer in Denmark you may drive at most 80 km/h, or 100 km/h on the motorway if the trailer is approved for it.

Charging with the caravan attached

At most rapid chargers you park in a normal parking space, and there is no room for the caravan. Some new charging stations have drive-through bays. Otherwise you have to unhitch the caravan or park so you do not block others. Plan your stops so you charge somewhere with plenty of space.

Plan shorter legs

Expect to charge more often than usual. Arrive at the charger with 15–20% in the battery, so you have a little margin. Charge to around 80% and drive on. Above 80% the car charges more slowly.

At the campsite

At the campsite you can charge from the site's socket with a portable charger, if the site allows it. Read more in the guide on campsites and holiday homes.

Checklist

Check in the registration certificate what the car may tow.
Expect up to double the consumption with a caravan.
Find chargers with room for the caravan.
