Electric car charging glossary

Volt (V) - The unit of electrical voltage.

Kilowatt (kW) - Kilowatt, a unit of power.
One kW equals 1000 watts (W). The term kW is used to describe the amount of electricity an electrical device uses at any given moment, or the charging capacity of an electric car charger. The higher the power, the faster the car is charged.

Kilowatt hour (kWh) - kilowatt hour, a unit of energy.
One kWh equals 1000 watt hours (Wh). In the example of an electric car, the battery size is given in kWh and means how much energy can be stored in the car and how long the range is. The larger the battery capacity, the longer the range when fully charged. Energy is calculated by taking power x time.

Ampere (A) - The unit of electrical current that tells how much electricity can be drawn at the same time. The larger the fuse and the higher the amperage, the more electricity is available to charge.

AC – Alternating current

DC – Direct current

Charging station, charging post, charging box – Different names for equipment that charges the car.

Destination charging – A term used to describe charging that takes place at the destination where you drive the car and park for a longer period of time. This can be the workplace, parking garage, hotel, hospital, etc. The term Destination charging refers to Normal charging / AC charging.

On-board charger
Inside every rechargeable car is an on-board charger, which is used during AC/Normal charging to convert alternating current to direct current to store in the battery. The on-board charger always sets the maximum limit for how fast a normal charge a car can receive.

Range
Indicates how far a rechargeable car can travel when fully charged.
On average, an electric car consumes 2 kWh per mile. This varies of course depending on the size of the car and the weather. In colder weather, an electric car consumes more.

BEV - Battery Electric Vehicle or Elbil in Swedish.
A car that only uses an electric motor for its propulsion, can be charged both through normal charging (AC) and fast charging (DC). Different car models can receive different fast charging.
During normal charging, charging takes place with powers between 3.7 - 22 kW (AC).
During fast charging, charging takes place with powers between 50 - 350 kW (DC).

PHEV - Plug-in Hybrid Electric Vehicle or Laddhybrid in Swedish.
A car with both a combustion and electric engine, range with electric drive often amounts to between 20-100 km depending on the car model. Can be charged through normal charging (AC) and different car models can charge at different speeds. Can usually be charged with powers up to 3.7 kW. In rare cases up to 7.4 kW.

Fast charging
Fast charging takes place at a so-called Fast charger, here charging takes place with DC/Direct current which is transferred directly into the battery for storage and the car's on-board charger is not used in this case.
Within the EU, the standard for this connector is now CCS.
Different car models can receive different fast charging but generally this type of charging takes place with effects of between 50 – 350 kW.

The charging effect during fast charging is affected by several factors such as:
1. Temperature (At low temperatures, charging is slower)
2. Charge level in the battery (At low charge level, charging is faster and decreases as the charge level increases)
3. Car model

Normal charging
Normal charging takes place through a charging box mounted at the parking lot, this type of charging takes place with AC/Alternating current and the car's built-in on-board charger then converts alternating current to direct current for storage in the battery.
Different car models can receive different fast charging but generally this charging takes place with effects between 3.7 – 22 kW.
In the EU, the standard for this connector is now TYPE 2.

Aimo Park offers Normal Charging in many of our parking garages, all of our charging boxes are equipped with TYPE 2 connectors to fit electric cars and plug-in hybrids and can deliver power between 3.7 - 22 kW depending on the system and car that is connected to the charger.

Load Balancing - Static or Dynamic
When installing electric car chargers, it is usually necessary to install some form of load balancing. Load balancing means that you limit the total power that one or more chargers can use together at any given moment in order not to exceed the total capacity of the property.
In static load balancing, you tell a group of chargers how much power they collectively have access to at any given time. This usually means that at high occupancy, all cars get charged, but that the charging speed (power) decreases. This type of load balancing does not take into account other electricity consumption within the property.
In dynamic load balancing, an electricity meter is installed in the property that measures the total electricity consumption for the property, then the electricity meter tells the charging boxes how much power is available for the charging boxes. The available power for the charging boxes often varies throughout the day because other electricity consumption in the property goes up and down and can then mean that the speed of charging varies. This type of load balancing provides a better opportunity to utilize the capacity to the maximum.
When you park your electric car for a long time, from a few hours to a day, there is plenty of time for the charging box to fill the car's battery even if the charging power drops during parts of the time.

Charging times
To calculate how long it takes to charge the car, you need to know a few things.
1. How big is my battery?
2. With what power can I charge the car?
Example:
An electric car with a 78 kWh battery size should be charged from 0-100% at a charging box that can deliver 11 kW.
Charging time = 78/11. Approximately 7 hours.

Alternatively
1. How far should I drive until I can charge the next time?
2. With what power can I charge the car?
Example 2:
You are going to drive 200 km with an electric car that consumes 2 kWh/km. This means a total consumption of 40 kWh. Charging these 40 kWh with an 11 kW charger means: 40/11 = Approx. 3.5 hours of charging.

Type 1 or Type 2
There are 2 different connector types for normal charging of cars. Type 1 and Type 2.
Type 2 is the EU standard and is found on all cars sold in Sweden today. The Type 2 connector supports 1-phase and 3-phase charging up to 43 kW (in reality no more than 22 kW).
All charging boxes in our parking garages are equipped with Type 2.
Type 1 is found on older cars from mainly Asian car brands. The Type 1 connector only supports 1-phase charging up to 7.4 kW.

CCS - Combined Charging System.
A connector type for both AC and DC charging.
EU standard for electric cars that can be fast-charged. A combined connector for both AC and DC charging. The upper part of the connector is identical to Type 2 and is used for normal charging of the car (AC). The lower part of the connector is used for fast charging (DC).
