The most common charging questions — and the answers

As a new EV owner, it is perfectly natural to have many questions about charging. We have collected the questions we get asked most often and provide you with clear, simple answers. After reading this article, you can charge with confidence.

Can I charge my EV in the rain?

Yes, absolutely! EVs and charging stations are designed to withstand all kinds of weather — rain, snow, cold, and heat. The charging connectors are watertight when connected, and there is no risk of electric shock.

The car and charger communicate electronically and ensure that power only flows when everything is safely connected. You can safely charge in pouring rain without worrying.

Can I leave the car charging overnight?

Yes, that is actually the most common way to charge. Most EV owners plug in the car when they get home and let it charge overnight. The car and charging box manage the charging automatically and stop when the battery is full.

There is no risk of overcharging. The car's battery management system (BMS) ensures the battery is not charged beyond what is safe. You can compare it to leaving your phone charging overnight.

Is fast charging harmful to the battery?

Not in practice, but it is good to vary. Modern EVs are built to handle fast charging. The car's battery management system protects the battery by automatically regulating the charging power.

That said, most car manufacturers recommend using home charging as your primary source, and fast charging when you need it — for example, on road trips. A mix of home charging and fast charging is completely unproblematic for the battery.

Some simple rules of thumb:

• Charge to 80 percent in everyday use — it is gentler on the battery than always charging to 100 percent.
• Avoid leaving the battery at 0 percent for extended periods.
• Fast charge when you need to — the battery handles it just fine.

How long does it take to charge?

It depends on three things: battery size, charging type, and how much charge is already in the battery.

Can I use any charger?

Yes, generally. The vast majority of EVs in Norway use two types of connectors:

• Type 2 — for normal charging and semi-fast charging (alternating current/AC)
• CCS (Combined Charging System) — for fast charging (direct current/DC)

As long as the charger has the right connector, you can use it. Some older EVs use the CHAdeMO connector for fast charging, but this is being phased out.

You need an account with the charging operator to start charging. Some chargers also accept bank cards directly.

What does kWh mean?

kWh stands for kilowatt-hour and is the unit we measure energy in. Think of it this way:

• kW (kilowatt) is the power — how fast electricity is delivered. Compare it to the water pressure in a tap.
• kWh (kilowatt-hour) is the amount of energy — how much electricity you actually use. Compare it to how many litres of water you fill.

If you charge at 10 kW for one hour, you have charged 10 kWh. A typical EV uses about 1.5-2 kWh per 10 km, so 10 kWh gives you about 50-70 km of extra range.

When you see charging prices quoted in kr per kWh, you know exactly what you are paying for. You can see all prices→ from the various operators to compare.

Do I need an app to charge?

Usually yes, for public charging stations. Each charging operator has its own app where you start and stop charging, and pay. Some stations also accept bank cards or RFID tags.

For home charging, you do not necessarily need an app — you just plug in the cable and the car charges. But many charging boxes have apps that let you control charging, monitor electricity consumption, and schedule charging times.

Our tip: Start by downloading the apps for the two or three largest operators in your area. You can always add more later.

What happens if the power goes out while I am charging?

No danger. If the power goes out, charging stops automatically. When the power comes back, most cars and charging boxes will automatically resume charging. The battery and car take no damage from a power outage.

Can I charge my EV with solar panels?

Yes! If you have solar panels on your roof, you can connect them to your charging box and charge your car with solar power. Many smart charging boxes let you control charging so that the car charges most when the sun is shining and the electricity is free.

This is a fantastic combination that makes EV driving even cheaper and more environmentally friendly.

Is it safe to charge my EV in the garage?

Yes, with the right equipment. EVs are designed to be charged indoors. The important thing is that you use an approved charging box installed by a certified electrician. Do not use a regular wall outlet or extension cord for permanent charging.

Summary

Charging an EV is safe, simple, and affordable. The most important things to remember:

• Charging in rain and snow is completely safe.
• Charging overnight is the most common way to charge.
• Fast charging is perfectly fine — use it when you need it.
• 80 percent is the magic number — charge to 80 percent for the best balance between time and battery health.
• You need apps to use public charging stations.
