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.

What is the difference between a rapid charger and high speed chargers?

It’s Friday afternoon and you’re on your way to the mountains. Both your passengers and your EV are low on energy, and you want to arrive at the cabin before it is too late. Should you choose a fast charger or a rapid charger?

Potentially seven times the charging speed

Rapid chargers provide higher power charging, i.e. faster / speed. A rapid charger, with 350 kW, will potentially be able to charge an EV at seven times the speed of a fast charger with a maximum charging speed of 50 kW.

It should be easy to recognise the different types of chargers at our charging stations. All charging stations are clearly marked with maximum charging speed and type of charger (normal, fast, or rapid) both at the charger and on our digital map of chargers.

Most of our fast chargers deliver a charging speed of max 50 kW, and we estimate charging times of 15 to 120 minutes, depending on vehicle type and battery level. A rapid charger can deliver charging speeds from 150 to 350 kW, and we estimate charging times of 10 to 45 minutes, depending on vehicle type and needs.

Actual charging speeds are limited by your vehicle

So, you are standing at a charging station on the way to the cabin and wondering what will get you back on the road fastest, the rapid charger or the fast charger. However, it is not actually the type of charger alone that determines how fast your battery will charge – it also depends on the make and model of your vehicle.

How fast an EV can charge is limited by how much power it can receive. For example, if you have a 30 kWh Nissan Leaf, it will be limited to be able to handle a maximum charging speed of 50 kW. EV manufacturers are constantly coming up with new models that can charge at a similar or higher power.

Faster charging speeds cost more

It is usually more expensive to use a rapid charger than a fast charger. You will be able to receive as much power as on a fast charger, but because the power is delivered faster, a rapid charge costs more. There are also higher operating and maintenance costs associated with delivering power faster.

If your EV can charge on a rapid charger, it will of course go faster, but it will also cost a little more. If you choose the fast charger, it may take a little longer, but you can stretch your legs a bit and prepare for the rest of the ride.

Frequently asked questions

  • What is the difference between kW and kWh?

    Kilowatt (kW) corresponds to charging power/speed.

    Kilowatt hours are probably familiar from your electricity bill: A kWh is the unit for the amount of energy you have received/used.

    For example: A charger that provides 50 kW of power, will under ideal conditions deliver 50 kWh of energy in one hour. 

  • What is the difference between a slow charger, a rapid charger and a high power charger?

    The three types of charger say something about charging power/speed, i.e. how long it takes the charger to supply power to the EV. Not all EVs can utilize the charger’s maximum charging speed. If you are unsure about which charging type is suitable for your EV, you can check with your vehicle supplier.

    • Slow charger: 3.6–22 kW. Estimated charging time (80 per cent) 3–10 hours.
    • Rapid charger: 50–150 kW. Estimated charging time (depending on battery level) 15–120 minutes.
    • High power charger: Over 150 kW. Estimated charging time (depending on battery level) 10–45 minutes.
  • 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.

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

Why am I not getting more power from a rapid charger?

A rapid charger will always try to deliver maximum power, but the EV’s battery management system determines the charging speed.

All EVs have a battery management system(BMS).The battery management system is the unit that controls voltage, current and temperature. The battery management system also determines how fast the vehicle will charge, i.e. the charging speed. It does this to protect the battery as much as possible. 

During a charging session, the battery management system continuously communicates with the charger to tell it how much power it should provide. EVs don’t charge at the same charging speed for the entire charging session, so if the battery is too cold/hot, or is nearly fully charged, fast chargers won’t charge very quickly.

Psst! If the charger is marked with a maximum of 150 kW, and your EV battery can charge at 350 kW, the charger will never provide more than 150 kW.

Our charging speeds

The charging speed says something about how fast the battery will charge. We measure this in kW (kilowatts). All our charging stations are marked with their maximum power. Find your nearest fast charger on our map of charging stations.

  • Slow chargers have a maximum power of 3–22 kW.
  • Rapid chargers have a maximum power from 50 kW.
  • High speed chargers have a maximum power of 150 kW and up.

This is what happens in the battery when you charge

When you charge an EV battery, positive lithium ions are pushed over to a negative electrode until it is full. When the battery approaches a full charge, space also becomes cramped. Then, the electrode takes longer to free up space for the lithium ions that are on their way over.

This is the reason why the charging speed is reduced when you have reached a certain voltage level in the battery cells, usually when the battery is between 70 and 80 per cent charged.

The temperature for optimal battery charging is between 20–24 °C. Charging speed will drop if the temperature is too low or too high. When it is cold, the lithium ions will move more slowly in the electrolyte. 

The electrochemical processes are also sensitive to high temperatures; even at the same charging power, the voltage in the battery pack could become higher than at more ideal temperatures. This could damage the cells, so the battery management system must reduce the charging speed.

Ordboken for elbilister!

Det er kilometervis med nye ord og begreper man skal forholde seg til som elbilist. Her har vi forklart noen av de vanligste. Dette er ordboken for elbilister!

A – F

  • A

    AC
    Alternating current.

    AC charger
    An AC charger is the same as a normal charger.

    AC charging
    AC charging is charging at a charge point that offers alternating current. The EV has an onboard charger that converts this to direct current. All batteries use direct current. The onboard charger is a bottleneck for charging speed. When you charge your EV at home, it is AC charging.

    Adapter
    Cable transition.

  • B

    Battery management system
    The battery management system in the EV monitors the battery’s charge level and controls the vehicle’s power consumption. In addition, the system determines how fast the battery will charge – which is why we say that the vehicle determines the / speed, not the charger. 

    BEV
    BEV stands for battery electric vehicleThis is used for all-electric vehicles, and not for chargeable hybrids.

    Blue adapter
    Adapter used in a blue industrial outlet with 32 amps on 230 volt systems. Provides charging power of 7.4 kW.

  • C

    CCS
    This fast charging standard is newer than CHAdeMO, and has become a European standard. Most new EVs usually come with this standard. CCS provides charging power up to 350 kW for compatible models.

    CHAdeMO
    Originally a Japanese charging standard and cable type. Some older Asian EVs use this connector. Of EVs available on the market today, only Nissan still uses it. In addition, Tesla can use this type with a CHAdeMO adapter. CHAdeMO provides charging power of up to 62.5 kW, but usually only up to 50 kW in Norway.

  • T

    DC
    Direct current. Used for fast charging. With DC, the EV’s onboard charger is bypassed, and charging takes place directly from the charging station to the battery.

    Dynamic load balancing
    A charging station with dynamic load balancing ensures good utilisation of the power grid, by distributing available capacity to the charging points in use.

    Charging station with dynamic load balancing
    At charging stations with dynamic load balancing, the charging speed (power) will vary based on how many vehicles are using the system at the same time and how much power is available.

  • E

    Effekt
    Effekt er hastigheten på hvor fort strømmen fylles på batteriet. Vi kaller det for ladefart. Effekten oppgis i kilowatt (kW). 

    Power (kW)
    Power is the charging speed and is measured in kW. A charging station may have one or more charge points or charging cables. You can see the maximum power available per outlet/cable at the charging station. The power available can vary at all types of charging stations, including fast chargers. The power stated is the maximum power the charging station can provide, but be aware that your vehicle may limit the charging speed.

    EV
    EV stands for electric vehicle. In many countries, the term EV is used for both all-electric vehicles and chargeable hybrids. 

    EV
    EV stands for electric vehicle An electric vehicle is a vehicle that is powered by electricity and not an internal combustion engine. The energy for propulsion is usually stored in batteries. 

    Estimated range
    The vehicle’s range based on previous consumption on the drive.

  • F

    Fast charger
    A fast charger provides charging speeds between 50 and 100 kW. It is faster than a normal charger, but slower than a rapid charger. Fast chargers have fixed CHAdeMO and CCS cables. Some also have an AC outlet or an AC cable. Only one car can charge at a time on a fast charger, unless it also has an AC outlet/cable – then this can be used as well.

    Fossil vehicle
    Fossil vehicle has become a term used by the media to describe vehicles with internal combustion engines.

  • H

    Home charger
    A home charger is what we generally call a wall charger. . The Norwegian Electric Vehicle Association recommends that you install a home wall charger (also called a “home charger”) where you normally charge your EV. A wall charger allows you to charge your EV more safely and quickly than if you use a standard outlet. This is because wall chargers are made especially for electric cars.

    Rapid charger
    A fast charger provides charging speeds between 50 and 100 kW. It is faster than a normal charger, but slower than a rapid charger. Fast chargers have fixed CHAdeMO and CCS cables. Some also have an AC outlet or an AC cable. Only one car can charge at a time on a fast charger, unless it also has an AC outlet/cable – then this can be used as well.

    Hybrid
    A hybrid vehicle uses both an internal combustion engine and an electric motor as a power source. Most hybrids can be charged, but only a few use regenerated power. Hybrids have a much shorter range when driving on electricity than electric vehicles. But hybrids can switch to propulsion with an internal combustion engine along the way.

     

  • I

    ICE
    ICE stands for internal combustion engine. The term ICE is often used for a vehicle with an internal combustion engine (fossil vehicle), i.e. in contrast to an electric vehicle.

    ICEd
    Used to describe a situation when a fossil vehicle is blocking a charger. Plays on the word “iced”. Often generates a lot of angry comments on social media.

    Combination price
    On some chargers, you only pay for the power you receive. The price is slightly higher than the kWh price you pay for the electricity at home, because access to higher power is more expensive, in addition to covering costs for the charger and other expenses. 

    kW
    kW stands for kilowatts and says something about how fast the electricity enters the EV battery. Kilowatt measures the power, or the charging speed. If you charge at 50 kW for one hour – you will receive 50 kWh of power.

    kWh
    kWh stands for kilowatt-hour. In Norwegian, it is “kWt”.

    kWt
    kWt is the Norwegian abbreviation for kilowatt-hours and measures power consumption. Your home electricity bill states your power consumption in kilowatt-hours.

    kWt-pris
    På noen ladere betaler du for strømmen du får. Prisen er litt høyere enn kWt-prisen du betaler for strømmen hjemme, fordi tilgang til høyere effekt er dyrere, i tillegg til å dekke kostnader for laderen og andre utgifter. 

  • L

    Ladeboks
    Ladeboks brukes om den ladestasjonen man ofte har hjemme. Den gir god sikkerhet og lader raskere enn i vanlig stikkontakt. Når man lader en elbil med ladeboks benyttes en spesiell elbil-kabel som er laget for å tåle høy belastning over tid. Det finnes ladebokser med og uten fastmontert kabel. Å lade med en ladeboks kan redusere kostnader når strømprisen er høy.

    Ladefart
    Ladefart er betegnelsen på hvor fort strømmen fylles på batteriet. Vi måler denne effekten i kilowatt (kW).

    Ladepunkt
    Et ladepunkt er det samme som et ladeuttak. Nen av våre ladere har flere ladeuttak/ladepunkter, det gjør at flere elbiler kan lade samtidig.

    High power charger
    A rapid charger is a type of charger with a charging speed of 100 kW or more. They have fixed cables, usually one CHAdeMO cable and one CCS cable, or they can have two CCS cables. Two vehicles can use a rapid charger at the same time and share the available power. Not all vehicle models can take advantage of the high power of a rapid charger, but they can still receive a charge from a rapid charger.
