World Premiere: 800 Volt charge park by Porsche in Berlin


High Power Charging (HPC) via CCS is Porsche’s answer to Tesla. It is ultra-fast, ultra-strong and liquid-cooled

HPC-charge point-PorschePorsche drivers opting for the Mission E once it hits the road by 2019 will not have to compromise as Porsche is taking their mission rather serious. VW’s sports brand today opened the first public charging site featuring its liquid-cooled 800 Volt technology and we were at the launch.

Porsche Germany’s CEO Jens Puttfarcken’s vision is clear: “Once the E hits the market in 2019, buyers shall have peace of mind to travel around Germany in the first series electric car with 800-volt technology.” And preparations have started now at a brand-new branch in Berlin-Adlershof that includes the first public fast-charging park with the 800-volt technology developed by Porsche Engineering. The first two such charging stations with 350 kW capacity just opened in the south of the German capital. They cover 180 to 950 volts and also offer lower charging capacities such as 50, 80 or 150 kW all via the Combined Charging System (CCS).

The Berlin charge park is ready to accommodate another two high-voltage charge points, while two AC stations for Volkswagen’s plug-in hybrid models complement the site. All eyes will be on Porsche’s high power chargers however, and their futuristic design drawn up by Porsche Engineering was called “close to serial” by experts on site. Michael Kiefer, who heads the High-Voltage Systems at the Porsche subsidiary, clarified that the optics are in fact final because the system is already undergoing certification.

Porsche’s 3rd centre in Berlin is now the site of Germany’s fastest charging stations

For Kiefer, high power charging based on 800 Volt is the future and it took him and his team of 70 two years to come up with a solution to the following problem: DC charging currents of several hundred amperes put an extreme load on the cables because they get so hot. At the same time, wire size is limited because the cables would become too stiff to manage at a certain point.

Porsche’s solution is to cool the charging cables as well as the entire area with a liquid made from a glycol/water mixture. If necessary, the same solution can also heat the cables to prevent them from rigidity in minus temperatures.

Adlershof, Berlin’s third Porsche center thus got the most powerful loading infrastructure in the Republic probably. It will be accessible during the store’s opening hours but will not go online autumn. Use will be free of charge at least until the back end is final.
“This facility marks the start of serial production of electric mobility at Porsche,” says Kiefer. Test runs with other electric vehicles such as the BMW i3 and VW e-Golf as well as prototypes of the Mission E will happen here in the future. Meanwhile, a second public facility is under construction at the sports carmaker’s U.S. headquarters in Atlanta.

Smart charge points and novel transformer in detail

The pioneering charge points with a CCS connector each, feature a display and card reader and also a heat exchanger and charging controller. DC counters for an accurate account of the current output are to follow. The six to seven kilo light cable has a length of 6.5 metres and is hanged high enough to not brush the ground. The coolant that runs underneath the sheath and envelops the inner cable is clearly feasible and reaches close to the contacts. The connector design is particularly handy and conveys high quality one would expect from a premium brand.

To ensure 350 kW will be delivered consistently, the Berlin station has got its own substation that connects to the medium-voltage grid in this case. While conventional transformers rely on one coil, Porsche here designed the system so that each HPC charge point got its own. “This ensures that each charging point always delivers the full power of up to 350 kW,” explains Michael Kiefer and adds that the facility achieves a total efficiency of a remarkable 97 percent. In front of the dark transformer stand the so-called flexboxes with power electronics and cooling.

According to Porsche Germany CEO Jens Puttfarcken, the company is currently looking into equipping all the country’s Porsche branches with such 800-Volt charge parks. Two HPC charging stations could soon be the standard. Wherever there is no connection to the medium-voltage grid, stationery storage shall buffer peaks to guarantee the full 350 kW. Porsche will do anything but compromise, it seems. “There won’t be any power-sharing like at Tesla Superchargers,” says high-voltage expert Michael Kiefer, not without pride in light of this holistic approach. Porsche puts the bar high, this world premiere of High Power Charging shows.

Baden-Württemberg


The world’s most car-centric region is Baden-Württemberg with its capital Stuttgart. It is where the German car industry’s hearts beat most strongly and has transported combustion engine technology and lastly diesel through its veins – so far. But this is to change due to players like Tesla, who is turning California into a centre of electric car making. On top, emission rules are being tightened worldwide and carmakers under scrutiny. It is in this climate, Clean Energy Wire set its media tour, which saw us travel to Stuttgart to learn, where the Germans are at when it comes to making a transition in transport.

How to turn Germany’s ultimate car city into a sustainable urban space.


Traffic-Stuttgart

The world’s most car-centric region is Baden-Württemberg with its capital Stuttgart. After all, it is here that Bertha Benz drove the first Daimler and to this day it shelters Mercedes, Porsche and suppliers like Bosch or Mahle. The heartbeat of the German car industry can be felt most strongly here and has transported combustion engine technology and lastly diesel through its veins – so far.

But this is to change. It must due to players like Tesla, who is turning California into a centre of electric car making and innovation anxiously eyed worldwide. On top, the EU as well as regulators in Beijing increasingly tighten their emission rules and since Volkswagen has been caught cheating, the entire (German) industry has come under scrutiny.

It is in this climate, Clean Energy Wire set its media tour, which saw an international group of journalists travel to Stuttgart to learn, where the Germans are at when it comes to making a transition in transport. Our correspondent Nora Manthey reports. (more…)

Urban Infrastructure – Part 4. LONDON: How to keep moving the masses by all means?


Urban-Infrastructure_610x340_London

How do electric cars get cleaner energy and cities better air? The series Urban Infrastructure from electrive.com highlights the different strategies with which cities in Europe develop infrastructure for electric vehicles. After Hamburg, Stuttgart and Berlin electrive.com Editor Nora Manthey takes a critical look at charging infrastructure and transportation in London, the capital and most populous city of England and the United Kingdom.

air quality crisis

Transport is moving in London, slowly at times, but move the British capital must by all means. Mobility is of the essence in a place that hosted 31.5m tourists in 2015 and has about 850,000 commuters flocking to the city every week day. A stand still is a disaster. Congestion is as pressing a problem as air pollution, and London keeps failing to meet EU standards.

Sadiq-Khan“Make no mistake: London is in the midst of an air quality crisis. Air pollution is permanently affecting children’s lung development and nearly 10,000 Londoners are dying early every year due to the long-term exposure of London’s dirty air.”

Mayor of London, Sadiq Khan

Both the UK government and the recently elected Mayor of London, Sadiq Khan, pledged to tackle the issue and put electric transport high on their agenda. The commercial level too, is taking an electric approach as initiatives like the sole EV charging network Source London experience new ownership.

Yet, London poses many a challenge to any concerted (electric) transport action due to its structure. Infrastructure here is a matter of public and semi-public transport as much as it is of private cars. All forms are increasingly electric – or shall become – but have to meet peculiar challenges in the British capital. (more…)
