Electric car batteries are charged with direct current, but the one that connects to a normal outlet is variable. Typically, 7 to 22 kW of power is charged by converting current to direct current from the device installed in the electric vehicle itself, the report says. High-speed AC charging stations provide up to 43 kW of power, but the principle is the same.
High-speed DC charging stations allow you to bypass internal converters and supply power directly to the electric car battery, resulting in power of 50 kW and above.
Infrastructure is already lagging behind
The blog “100 percent. Electrical author Dainius Jakas explained that the only way to increase the charging speed of the stations is to increase the voltage, which is very expensive. It is difficult to increase the current further because the wires start to get very hot.
“The Vilnius Vokiečių street stop already has cooled cables, because there are a lot of amps and they can only be reduced in one way: by increasing the volts. It automatically turns out that if you don’t want to cool the cables with liquid nitrogen, you have to increase the voltage, ”said the electric car expert.
According to D.Jak, the 50 kW charging can be considered fast, but if the installation of new stations is planned at least five years in advance, the charging speed after that period will be too low.
The expert hinted that so far there are no electric cars that can take advantage of the maximum charging speed of 350 kW in today’s stations, but this is a more theoretical problem. According to him, in practice, the situation is reversed: many modern electric models can be charged with more than 50 kW, but such stations, although their number is growing, are still very few.
It will be an important advantage in the future.
The faster charging provided by manufacturers makes compact models such as the Peugeot e-208 more versatile and suitable not only for urban driving. D.Jak noted that the buyer of such an electric car has a reserve of charging speed, which will be an advantage as soon as more powerful stops appear. This will also have a major impact on aftermarket sales: Peugeot’s 100 kW charging speed is higher today than its competitors, but it will become the market standard in a few years.
D.Jak also pointed out that even when traveling in an electric car, fast charging is not a deal breaker. You also need to assess how far you can travel on a charged battery – that is, how often you will have to stop to replenish your power supply. According to the expert, this allows a clearer image.
“For example, the Audi e-Tron is an inefficient electric car, consuming a lot of electricity, but with access to the necessary infrastructure, its battery can be charged very quickly,” he said.
Small electric vehicles like the MINI Cooper SE or the Peugeot e-208 generally have similar mileage to the WLTP, while the larger and heavier models like the Audi e-Tron or the Porsche Taycan tend to have shorter distances.
Provide safeguards
The blog author acknowledged that the average buyer rarely immerses himself in the niceties of using an electric car, and charging speed is often a surprise. He joked that people buy what they like and then clarify the things they need to know up front.
Here, just like when you go to the cabin, they tell you that a car will consume an average of 4 liters of diesel per 100 kilometers. Finally, it turns out that you like to drive at 160 km / h on the highway. Fuel consumption is “slightly” higher and possibly reaches 12 liters, “laughed the interlocutor.
Fast charging of electric cars does not hurt; Often in doing so, modern model batteries, unlike a laptop or smartphone, will not suffer as manufacturers use systems that protect batteries from such damage.
For example, batteries in modern Audi, Peugeot or Porsche electric cars get cold and do not overheat with frequent use of fast charging. And if the maximum power is set to charge too frequently, the charging speed may be temporarily limited. In that way, electric cars from older manufacturers are fundamentally different from less practical ones like the Nissan LEAF – the lack of battery cooling makes this model somewhat impractical.
Efficiency is also guaranteed by the manufacturers themselves: Peugeot or Volkswagen give their batteries for 8 years or 160 thousand. km warranty.
