Piëch Automotive unveiling Piëch Mark Zero electric sports car at Geneva; 500 km range, 80% charge in 4:40 minutes

Piëch Automotive will unveil the Piëch Mark Zero electric sports car concept at the Geneva Motor Show this week. The Mark Zero is the first of a family of products to be brought to market by Piëch Automotive over the next three years. Three vehicle variants are in planning: a two-seater, a four-seater and a sporty SUV. Other concepts such as convertibles or pick-ups are also conceivable.

A flexible and open vehicle architecture allows the use of a variety of drive systems—electric drive, hybrid, fuel cell or internal combustion engine.

The Piëch Mark Zero is an electric GT with a range of 500 km (311 mi) according to WLTP. Acceleration is expected to be 0-100 km/h in 3.2 seconds, with a top speed of 250 km/h.

A special type of battery cell hardly heats up during charging or discharging phases. Significantly higher currents can flow as the cell temperature rises only marginally.

In addition to conventional CSC charging, the fast charging mode allows for a sensationally short charging time of only 4:40 minutes to 80% battery capacity with an exceptionally high recuperation rate. Because of the reduced heat build-up, the batteries can be cooled by air alone. This contributes to an overall weight reduction of around 200 kg, resulting in a total vehicle weight of under 1,800 kg.

At the front axle, an asynchronous motor delivers 150 kW, while at the rear axle, two synchronous motors produce 150 kW each.

Piëch Automotive’s battery partner is the DESTEN Group Ltd., based in Hong Kong, China, with a research and development center in Qingdao, China. DESTEN offers innovative cell and battery packs which feature extremely short charging times combined with low temperature development. Now DESTEN wants to roll out their battery and cell competence gained in the consumer sector in the automotive industry.

The necessary charging infrastructure is supplied by Qingdao TGOOD Electric Co. Ltd. from Qingdao, China, and Hong Kong, China. The group of companies was founded in 2004 by Chinese and German engineers, is listed on the stock exchange in Shenzhen, China, and is a market leader in eHouse solutions. TGOOD operates 210,000 charging stations in more than 300 cities.

Due to the placement of the battery packs (one in the center tunnel, the rest at the rear axle), weight distribution and handling are expected to be similar to that of a conventional sports car with a combustion engine. In contrast to the widespread placement under the floor, this allows a low seating position typical of a sports car as well as precise handling, giving the driver immediate feedback.

I was wondering who was trying to go head-to-head against Tesla.

China.  It figures.

HarveyD

I have to agree with SAEP that China has the market, knowhow and resources required to meet and surpass TESLA and eventually run the Big Three to bankruptcy unless?

With a range of 500 Km and a very quick 80% charge under 5 minutes, this new made in China BEV will/may compete against equivalent ICEVs, if the total price is right?

Public charging facilities will have to be upgraded to deliver that many KW in 5 minutes.

Interesting concept car from Anton Piech who is the son of Ferdinand Piech, former Chairman of VW and great-grandson of Ferdinand Porsche.
The battery and charging infrastructure are from China. Not sure where the automobile will be made except that is made by partners with a long history of success in contract manufacturing (probably Magna a supplier to VW).

80 kWh in 5 minutes is charging at close to 1 megawatt,
good luck with that. That is 800 VDC at more than 1000 amps.

An good device for the race course; but, what is the life of the battery? How dangerous is charging this battery? What safeguards are required, What is the temperature rise in the battery when charging, etc., lots of engineering questions.

HarveyD

Yes SJC, transferring that many KW in 5 minutes would require super charging facilities like (800 VDC @ 1200 Amps), super cables and special connectors. Increasing recharges to 10 minutes would effectively reduce current by 50% to about 600 Amps and could be achieved with very special charging facilities.

A smarter solution may be and on board FC range extender and smaller batteries to keep an extended range of 500+ miles and total cost low? More clean H2 stations would be required.

Correct existing Fast DC Charging Stations will not charge the Piech Mark Zero in 5 minutes. Even the DESTEN Group web site posted an article that pointed out that the ABB 350 kW Charger would not do this.
However, China (GB/T standard) and Japan (CHAdeMO) are planning to implement a new standard that will set the limit to 900 kW (1,500 Volts x 600 amperes) which would meet the demands of this battery (assuming an 88 kWh battery) . (Reference: https://spectrum.ieee.org/energywise/transportation/efficiency/a-global-charging-standard-for-evs).
. . .
Of course, you need the right battery. two technologies will meet the requirement of a 5 minute charge - StoreDot and Enevate. StoreDot has an agreement with EVE Energy, a large Chinese battery manufacturer. Enevate has an agreement with LG Chem, while a Korean company it has two battery plants in China and is also the VW supplier.
. . .
While this post states that DESTEN Group will supply batteries, they appear to be a System Integrator not a large battery manufacturer. Their web site does not describe any battery products. My bet is the cell supplier is Enevate/ LG Chem.

SJC

The Porsche is suppose to be 800 VDC but not 1200 amps.
Getting another 200 miles in 10 minutes sounds good,
but pack life is a factor.

Gasbag

311 miles of WLTP translates to about 250 miles EPA. For a small low profile light vehicle like this that likely means a battery in the 55-60 kWh range.

The 280 second 80% recharge time implies a charge rate of ~10 C so were talking more like 550-600 kW. Even if charging infrastructure only supports half that rate market research indicates 94% of drivers would find 10 minute recharge time acceptable.

The charge rate and the fact that it is air cooled sounds like they are using CATL’s EnerSpeedy product.

Did a little detective work on this concept and it may not be hype at all.
. . .
The Piech Mark Zero does not only look like an Aston Martin it probably IS one!
According to Automotive News an unnamed buyer paid $26 million for the tooling and design drawings associated with the Vanquish coupe and convertible. The Piech Mark Zero is almost a copy of the Aston Martin Vanquish.
. . .
The Aston Martin Rapide which is related to the Aston Martin Vanquish and has a similar bonded aluminum body frame was built by Magna Steyr in Austria until 2012.
. . .
The planned Aston Martin Rapide E has an 800V 65 kWh and a 200 mile WLTP range.
So the Mark Zero may have a similar size battery and since it is lighter could have a 311 mile WLTP range (really 250 miles as pointed out earlier).
. . .
A 400 kW DC Fast Charger like the ChargePoint and planned GM chargers would charge this battery to 80 percent in less than 10 minutes, i.e. less than 40 kWh.
. . .
The Aston Martin Vanquish chassis was built to handle 600 hp and the 201 hp motors in the Mark Zero look like standard VW ID electric motors.
. . .
The batteries according to DESTEN are 10 C and have a power density 1600 W/kg. This could be a Solid-State battery like the one in low volume production at Qing Tao Energy Development Co, a startup spun off of Tsinghua University. Their research was published and posted in GCC (https://www.greencarcongress.com/2019/01/20190103-sslmb.html).
