The difference between EV chargers

Do you find it difficult to remember which type of charger you normally use, should use or cannot use? Here is the overview you need to choose the right charger for your EV!

Why is it really so important to choose the right EV charger? Well, there are two good reasons for that. Firstly, it will cost you much less if you choose the right charger for the right use and EV model. Secondly, you contribute to reducing waiting times at charging stations – and that’s something we all really appreciate when we are on the go. Especially if we are in a bit of a hurry and “just need a little” top-off.

The different types of charger

At our charging stations, you can choose between three types of chargers; slow charger, rapid charger and high speed charger. They all have different properties and will provide different charging power.Remember that it is ultimately your EV that determines how much electricity you can receive. This means that even if you use a high speed charger, it is not certain that you will get the full benefit if your battery does not have the capacity for that level of charging speed.

If you are unsure of the type of charger that fits your EV, we recommend that you contact the manufacturer. Most EV manufacturers have clear information on their websites.

Slow Charger

Slow chargers are the original EV charger, and the first type of charger we installed. Today, this may not be the charger we prefer most often, but on the other hand, there is seldom a charging queue! Slow chargers are perfect when you have a lot of time. If you are going to the cinema, on a longer shopping trip or on a visit.

Slow chargers are often found in car parks. If there are rapid or high power chargers in the same place, you will probably find a slow charger a short distance away from the others.

To use a slow charger, you must have your own charging cable with a Type 2 connector. The charging power varies from 3.6 to 22 kW. And depending on the make and model of your EV, we estimate a charging time of 3–10 hours, giving you plenty of time for both the cinema and your shopping trip.

Rapid charger

Rapid chargers are an efficient way to charge your EV – under optimal conditions. By optimal conditions for an EV battery, we mean that it is temperate (not too hot or too cold) and that the battery is neither flat nor fully charged. Remember that the charger will always give the charging effect it is marked with, and it is the EV that limits the charging speed.

Rapid chargers usually have two fixed cables (CHAdeMO and CCS). Only one EV can charge at a time, unless there is also an AC outlet/cable – then this can be used in addition. If you arrive at a charging station that has a free cable for fast charging, but it lacks an AC outlet/cable, you will not be able to charge if another EV is charging with the other cable.

Most fast rapid chargers deliver a charging speed of 50 kW, and we estimate charging times of 15–120 minutes, depending on the make and model of your EV, the required amount of power and the condition of the battery.

High speed charger

High speed chargers are our fastest charging option! These chargers deliver charging speeds from 150 to 350 kW, and we estimate that you can cover your charging needs in 10–45 minutes! How fast a high speed chargers will charge your EV is of course also related to the make and model of your EV, and the type and charge level of the battery.

Our high speed chargers have two charging cables, so more cars can charge at the same time. We also have high speed chargers with several associated “satellites”, and all of them can be used at the same time. Some satellites provide more power than others. If there are several available, check which one best suits your EV. The power output is marked on all the satellites.

Frequently asked questions

  • Why does my EV charge slower in the winter?

    Fast charging takes longer when the battery is cold. This simply has to do with battery chemistry; the ions move more slowly when the battery pack is cold than they do when it is warm. The cold does not affect the charging station itself. The charger provides the same power as it is marked with. It is the car’s battery management system that limits the charging speed to protect the battery.

    Tips! In order to speed up charging in cold weather, it may make sense to charge the EV when the battery is warm. For example, plan a charging stop towards the end of your trip.

  • Which charging cable fits my EV?

    There are several types of charging cables, and at many stations, you will be able to choose between several charging options.

    For slow charging you must always bring your own mode 3 type 2 charging cable that fits your EV. This is usually standard equipment on all new EVs. EVs normally come with two cables. You cannot use the charging cable that has a “normal” wall connector at our public charging stations.

    For fast chargers and high power chargers there are always fixed cables, and at most charging stations, you will find both a CCS/Combo connector and a CHAdeMO connector. Only one of them will fit your car. Most new EVs today come with CCS, which is the European standard for charging cables. Read about the different charging cables here..

  • Why am I not getting more power?

    How much power you get over a given time, i.e. the charging speed, depends on several things, including which EV model you have, what kind of charging station you charge at, battery temperature and the vehicle’s battery level.

    It is always the vehicle that decides how much power it can receive! It is the vehicle’s battery management system that limits the charging speed, to protect the battery.

    For example: An EV that cannot charge at higher power than 40 kW will not be able to get more than 40 kW – even if the charger has a maximum charging speed of 150 kW.

    All our charging stations are marked with their maximum charging speed. So, be aware that even if your EV can receive a charging speed of 150 kW, it will never be able to draw more power than what the charging station is marked with.
