One of the biggest problems with electric cars is still the charging time.

According to US researchers, there is a method that is much faster than before.

Many customers may now be able to cope with the range now offered by many e-car manufacturers – but less so with the charging time.

For owners who charge their Stromer every night in the garage at home, this is of course not an issue - but those who want to cover longer distances can run into problems.

With an increasing number of e-vehicles, the rush to the charging stations naturally increases and there can be extreme waiting times at peak times - such as last summer in Croatia or during the Christmas holidays in Great Britain.

In addition, when it is cold, the charging capacity at fast charging stations sometimes drops considerably, as the ADAC recently found out in a test.

Researchers from the USA have now allegedly developed a technology with which particularly fast charging should be possible.

Charge an electric car to 70 percent in ten minutes: nickel foil is said to increase the speed enormously

The approach taken by the researchers at Pennsylvania State University, which they published in the journal

Nature

in autumn 2022 : Instead of installing ever larger batteries in electric cars, it is better to install smaller batteries - and to charge them particularly quickly.

Because there are not enough raw materials for large batteries, the scientists believe that making batteries smaller is unavoidable.

With the new technology, it is said to be possible to charge an electric car battery to 70 percent in just around 10 minutes.

Currently, charging usually takes much longer - which is why many e-car owners are dealing with "range anxiety", like a couple in Florida recently.

Charge an electric car to 70 percent in ten minutes: It should work if the temperature is optimal

An ideal temperature window is important both for drawing power from a battery and for charging: not too hot and not too cold.

Only then can the current flow at high speed.

And this is exactly where the researchers have developed a corresponding solution, according to a statement from the university: the result is a new battery structure that, in addition to anode, electrolyte and cathode, contains a wafer-thin nickel foil as an additional fourth component.

Ten micro electric cars - Stromer perfectly suited for the city

Opel Rocks-e: Some might wonder if this is still a full-fledged car.

Legally, like all small cars, it is not.

If you want to drive it, you only need the driver's license class AM.

So it can be moved from the age of 15.

The electric motor delivers 8 hp and accelerates the mini electric car to 45 km/h.

More is not possible.

The 5.5 kWh battery is sufficient for a range of 75 kilometers.

After that, the 2.41 meter long Opel Rocks-e has to be plugged in for around four hours.

Cost: around 8,000 euros © Opel

Renault Twizy: The little Frenchman is something like the grandfather of micro electric cars.

The Twizy has been part of the Renault model range since 2012.

At 2.34 he is slightly taller than Rocks-e and Ami.

Instead of side by side, the two occupants take a seat one behind the other.

Side windows are only available as accessories.

Prices start at 11,450 euros.

Like the larger version wants to drive, however, requires a proper driver's license.

Renault specifies the range as 90-100 kilometers.

City Transformer CT1: Micro electric cars have also been discovered in Israel.

The CT1 from the start-up City Transformer lives up to its name.

Because the track width of the mini Stromer can be adjusted.

It is powered by two electric motors on the rear axle.

The start-up promises a range of up to 180 kilometers and a top speed of 90 km/h.

If you pre-order the CT1, you pay 13,000 euros, later it will cost 16,000 euros.

e.Go Life: At 3.3 meters, the e.Go Life is almost a giant compared to the other mini electric vehicles.

The 77 hp electric motor enables a top speed of 130 km/h.

In the city, he should be able to travel up to 206 km.

The combined range is 139 kilometers.

Due to the bankruptcy of e.Go in the summer of 2020, the Life was temporarily not built.

However, the business was taken over by Next.E.Go Mobile SE.

With the e.wave X, a Life successor is already available.

Microlino 2.0.Microlino 2.0: BMW built the Isetta light vehicle from 1955 to 1962.

The micro car is still a cult today and is now celebrating its comeback.

At least the Microlino 2.0 is very similar to the Isetta.

The micro-electric vehicle is available in three battery versions with a range of 95, 175 and 230 km.

The 20 hp electric motor accelerates the vehicle, which weighs only 450 kilograms, to 90 km/h.

At 14,990 euros, however, the Microlino is not exactly cheap.

Elaris PioElaris Pio: With a length of 2.81 meters, this electric dwarf is still under the three meter mark.

In this area, the boundaries between micro-car and passenger car are blurred. In terms of drive, however, the Pio is among the micro-electric vehicles.

The electric motor delivers just 49 hp.

The battery has 27 kWh and is enough for 225 kilometers.

The Pio is priced at 21,900 euros.

FreZE Nikob EVFreZE Nikob EV: The electric dwarf under the name Wuling Hongguang Mini EV is already very successful in China.

In order for this to be the case in Europe as well, more security and energy efficiency were needed in addition to a new name.

Means: ESP, airbags, new wheels and LED lighting.

The Nikob EV is offered with a 13.8 kWh LFP cell with a range of 200 km.

The small electric car should cost 16,000 euros.

Electrofrog Bob FourElectronic frog Bob Four: You don't really know what this vehicle wants to be.

Officially, the electric frog Bob Four is a cabin scooter.

Accordingly, 45 km/h is the end.

The electric frog should cover around 100 kilometers and that for just 8,990 euros.

In addition to the Bob Four, Elektrofrosch has other micromobiles on offer.

Ari 802ARI 802: At 2.22, the Ari 802 is very small.

At 643 kilograms, it is also very light.

Therefore, 10 hp are enough to bring the small car to 80 km/h.

In the versions 252 and 452 only 25 or 45 km/h are possible.

Ari states the range as 120 to 250 kilometers.

The price of the Ari 802 is 10,990 euros.

Charge an electric car to 70 percent in ten minutes: Researchers promise cheaper electric vehicles

"Our fast-charging technology works for most energy-dense batteries and will open up a new way to downsize EV batteries from 150 to 50 kWh without drivers experiencing range anxiety," said Chao-Yang Wang, professor of mechanical engineering at Pennsylvania State University and lead author of the study.

"The smaller, faster-charging batteries will drastically reduce battery costs and consumption of critical raw materials such as cobalt, graphite and lithium, enabling mass adoption of affordable electric cars."
