Why charging an electric car can sometimes be so slow

more and more Dutch people to find out more about electric cars, but especially in the charging station, they can sometimes be caught unaware. Why is it that it is charging, sometimes it is so slow? NU.nl the suppliers of charging infrastructure EVBox and Lanova, and the operator Fastned.

by the manufacturer of the promised speed is actually at the peak rate. This is the beginning of the laadsessie has been obtained, and, usually, only if certain conditions are met," says the Fastned. No matter how high the peak is, it depends on the car itself.

Other factors that play a role in the level of battery power, so how much you overhebt as soon as you have a charger for that matter, and the temperature management of the battery pack. "It Is the battery temperature, the specified load previously met, to when the packet is still very cold. In the summer, and plays an active accukoeling a role in this, because if the package is too hot to be charged in the car is less likely," says the company in this matter.

"the basis is going to be a number of factors, the teams of EVBox Group as well as Lanova separately. They point out that the power supply to the power supply, the setting, or the limit of the charging station, the charging cable, and the temperature and the electric car is capable of. At the point of loading, there is also a difference between alternating current (AC load, such as at public charging stations) and direct current (DC-to-load, such as, for speed loaders).

"The decision has been the greatest influence on this process and you can have it," said Fastned. "Do you have a vehicle with an active temperature management for the battery pack, make sure that it is set up, you are always optimally prepared for the journey ahead, or on the battery charger to arrive. Some cars do this automatically, while others you can do this."

It is suggested that you do not already have to charge it when the battery power is still 40 per cent of state. For a higher speed is better for the battery-empty-to-drive" adds Lanova is on.

at Home, you can use the wall outlet, but it's not as secure, and it is going to not be so fast. "You can buy a docking station for your home, then you will get a special usb cable, and a separate group in the hall. In this way, charge you a safer and faster, and you can park your car in a few hours to fully charge," said EVBox.

"The speed, that is, it is the limit of the charger and the vehicle. What is the lowest value that determines how fast it will go. So, if you are coming with a car, with a 150 kW load at a 50kW charger, then the charger is the limiting factor. If you have a car that is 50 kW, and can be loaded at a 300kW charger, the car is the limiting factor," explains Fastned out.

"When the power available at the loading location is limited, it may be that the current to one or more cars are being distributed, and therefore the speed can go down," says the Lanova to do that.

Well, if there's a fork in the power, you can limit an experienced, complete EVBox it. A 120kW docking station allows two cars to a 60-kW load. "If I had to be on my own, with up to 90 kW of the load, and am someone else, I'll certainly notice it."

"But it's snellaadpunt own terminal, that is, the ability for the corresponding fast chargepoint can make, then this is the rated power is guaranteed," said EVBox.

in Such a fast chargepoint is at Fastned: "Almost all of our drawers are fully functional independence. This is true for the chargers with 50, 150 and 175 hp. The 300kW shutdown is different. Since it has a closet and two plug-in connections. So, if you have two cars, it is the ability to spread out. Because of the more than 300 kW, did you, however, is only the burden of which was-more than 300 kW) for free.

the First time, you can offer the card, and that will only make a connection with the so-called backend server is in the charging station. Out of these communications via the cellular network, and there may be a slight delay in it, " says EVBox. "Sometimes it is the combination of a mobile phone, did you?"

in this communication is regular, then it is the contact between the vehicle and the charging point on the swing, also known as the interface is called. "Well, that can wait. Some of the cars are faster than others," said Fastned.

“We don't suffer from an evening at the net,”

"no, No, the two families have a proprietary power connector, and there is no influence on each other," said Lanova. "It's going to be pure in order to it's use in the home," says EVBox. "So, when I got home to cook, ben, and the machine is running and I plug my car in, and then it loads a little slower. But when I lie down to sleep, can have the power to draw".

Fastned: "In the city, we are the so-called medium-voltage network, and we have our own trafohuisje. Thus, to overcome the low-voltage grid, where all of the household to sit on. In other words, we have not been affected by an evening at the net."

"connect-the stations are well-standardized. Especially for the stations where you have your very own usb charging cable to plug in are expected to remain well in the older cars still have a long time to use it," said Lanova.
