With the proliferation of “fast charging” terminals, filling the full energy of electric car takes much less time. 30 minutes is enough to charge 80% of the battery! We explain to you how it is possible.
The “fast charging” terminals will save time for the electric vehicle’s drives. Due to them, the charging time of the battery is greatly reduced: 20 to 30 minutes only.
Advantage: Even with an electric car whose range is 200 to 300 km, it is now possible to consider longer journeys without having to plan long stops to refuel.
Why charging terminals are so fast?
If the charge terminals are faster than the domestic or industrial charging solutions, it is due to some technical differences.
The battery is recharged directly and not via the inverter of the car
In the case of fast charging, the inverter is not used. The “fast charging” terminals charge the battery directly. It can thus recharge the car much faster.
An electric car battery runs on DC power, the AC power grid. To be able to recharge the battery via the ordinary electric network, the car is equipped with an inverter that converts the AC current into direct current. However, the power of the inverter determines and limits the charging speed of the battery. The less powerful the inverter, the longer it takes to charge the vehicle. In the case of fast charging, the inverter is not used. The “fast charging” terminals charge the battery directly. It can thus recharge the car much faster.
The charging cable is attached to the terminal
Electric cars are, in principle, equipped with their own charging cable. They can easily be recharged at public terminals. You do not need this cable when you are refueling at Tesla Supercharging for FREE. It is equipped with a number of cables with different types of plug which allows compatibility of the terminal with most brands of electric cars.
The type of catch often depends on the country of origin of the car. In Belgium, four options are available:
- Combined charging system, or CCS Combo , for European cars (BMWi3 – Opel Ampera e – VW E-Golf – Hyndai Ioniq and soon the Audi e-tron and the Porsche Mission E)
- CHAdeMO, for Japanese and South Korean cars.
- Type 2- Mennekes high power for the Renault ZOE. With this plug the loading is slower than with the two previous ones.
- Tesla Supercharger, only for Tesla. It is the fastest charging station in the world. It can deliver up to 150 kW and soon 350 kW against 120 kW for others.
Load with a maximum power of 150 kW instead of 22 kW
The fast charging stations sometimes have a power of up to 120 kW and even 150 kW for the Tesla Supercharger. For the Tesla Model S, the gain of autonomy is 105km / 10 mints of loading.
If you charge your electric car at home, you will have at your disposal a refill solution with a capacity of 22 kW, equivalent to 10 fryers. If all the other factors are optimal (battery charging power, grid capacity and charging cable) you can expect to store 100 km in one hour. The fast charging stations sometimes have a power of up to 120 kW and even 150 kW for the Tesla Supercharger. For the Tesla Model S, the gain of autonomy is 105km / 10 mints of loading.
