New battery tech means EV charges to 80 percent in just five minutes
A Swiss-German electric car startup will launch a new car tomorrow with batteries that can charge to 80 percent in just five minutes.

The Piëch Mark Zero, launched tomorrow at the Geneva Motor Show,  uses a new type of battery developed by Chinese supplier DESTEN and charging infrastructure from Qingdao TGOOD Electric to provide the fast charging for a range of 500km (311 miles).

Piëch Automotive, based in Zurich and Munich, is aiming to launch a family of products in the next three years using a flexible and open vehicle architecture allows the use of a variety of drive systems that will be available to other car makers.

The new battery cell developed by DESTEN supports a higher current rate with minimal heating during charging and discharging phases and has a high rate of recuperation and can be charged up to 80% in 4:40 minutes with just air-cooling. This means that fast charging takes only marginally more time than filling up a conventional car with petrol, and contributes to an overall weight reduction of around 200 kg to under 1,800 kg.

Different placement of the batteries (one in the centre tunnel, the rest at the rear axle), rather than in the chassis, means weight distribution and handling are expected to be similar to that of a conventional sports car. At the front axle, an asynchronous motor delivers 150 kW, while at the rear axle, two synchronous motors produce 150 kW each

The vehicle supports conventional CSC charging, but the TGOOD chargers provide the fast charging. The Qingdao TGOOD Electric group based in Qingdao and Hong Kong, , was founded in 2004 by Chinese and German engineers, and operates 210,000 charging stations in more than 300 cities.

"We are proud to have found two such strong and innovative partners. Together with our partners, we're open for cooperation, regardless of whether it's about our new modular vehicle architecture or the innovative battery cells or the charging infrastructure," said Toni Piëch, Co-CEO and Chief Marketing Officer of Piëch Automotive.

The modular architecture for both hardware and software means the battery cells can be updated
