China State Grid Corporation building "superchargers"

It's not. I think it's kWh charged for pricing purposes like gallons/liters on a fuel pump.
If you multiply voltage and current, you get ~23.5 kW. Divide by 4 for quarter hour and you get 5.875 kWh.
Allow for some charging taper and time inaccuracy and the 6.6 kWh figure makes sense.
New article on the state grid chargers:
Beijing-Shanghai high-speed run to open the electric car is just a joke? - GeekCar
TL;DR:
* Microbloggers (i.e. Chinese twitter users) went out to test the new state grid chargers.
* The two cars used were Kai Chen Morrowind (i.e leaf variant) and a Model S.
* None of the state grid chargers they tested worked, despite being promised to be open.
* They had issues with the contactless payment system. 'High speed charging' card can't be bought by individuals. (?)
* Tesla charging is a better user experience, but they think harmonisation is necessary long term.

Several editors car home site today drove the electric car from Beijing, preparing for a trip to the Beijing-Shanghai line.
In their fleet, the two electric cars are Kai Chen Morrowind and Tesla Model S. Tesla drove away from Beijing to Shanghai has proven to be feasible, so the whole story of suspense is nominal mileage of 175 km bike morning breeze.
Their faith, or that the key to this plan can be implemented, because before the burst of news: the Beijing-Shanghai high-speed line opened fast charging system. Based on this, a life of more than 100 kilometers of pure electric cars to finish the Beijing-Shanghai line to become possible.
However, the team has just left the Beijing 200 kilometers, the story "the whole end of the play", the reason is that the national grid charging device on the highway all can not be charged. Si village shop, wangqingtuo, Jinghai, tangguantun four service areas without exception. So, this time, "the Beijing-Shanghai high-speed electric line 'had ended prematurely.
Qichezhijia host micro-Bo Yan Chuang explains why you can not use the charging pile: "National Grid to communicate the results: we buy IC card charge card is also the only market in the sale of the charge card, charge card high speed on the radio card, users can not buy; before the Beijing-Shanghai high-speed charging through the news, they did not say the opening of a national grid, two did not say open to individuals, we are wishful thinking. "
National Grid issued January 16 micro-Bo said: "National Grid in the Beijing-Shanghai high speed along the fast-charging stations built in 50, with an average 50 km each way per seat a fast charge station plans to build four sets of 120 kilowatts DC charger. 8 charging pile, which can for eight electric vehicle charging, full (80% capacity) within 30 minutes, the initial construction of two sets of charger, charge pile 4 support in line with China's electric vehicle charging standard. "
In this article microblogging with maps, including Kai Chen Morrowind, including a few electric cars are charging pile beside quiet charging service area, the car sticker that says, "the Beijing-Shanghai line 1.10-1.14 electric car."
The car is the same car, and even car home also made a similar body stickers, but their car Morrowind but because this "low-level" reason can not be charged.
Judging from the scene image, charging pile indeed using RF design, compared to the contactless IC card, RF card can be identified in a relatively far distance. But no matter which way the technology is not very deep, there was no difficulty in construction. For example, the bus card machine is mostly used in the RF mode.
Perhaps, only with the design side or the construction side, "oolong" to explain this thing. Of course, we should change the charging system RF contactless IC card payment system, it is not a difficult thing.
The car home to try all four service areas located in Tianjin territory, as the Beijing-Shanghai line along the Hebei, Shandong and other provinces if the charge is the same pile can not be used, is currently unknown.
Built charging pile network, could have been a happily good, but the large and small problems may still have a lot of. Improve the basic set up of just one aspect of how the user experience, probably is more important. In contrast, Tesla self charging network, the implementation of a destination charge of policy in this area there are no small advantage. Of course, this is only from the perspective of the user experience point of view, the long-term perspective, charging pile harmonization of standards is still necessary.
On this matter itself, halfway back home, may be higher than the successful completion of the task but also more meaningful, more dissemination of results.

Even if it does not work ok right now in practice, features above are good enough to feel good about it. They will have time to improve the execution.
China gets it, Europe on the other hand does not.

Those charging stalls look *awfully* familiar!
Hrmmmm Now I wonder where they got that idea from... haha!

Don't know what you mean, they are a different colour! :tongue:
I happen to have a 21 year old student from China staying at my house for a few days after spending a semester at UC Santa Barbara. I showed her that article. She said the charging station specs are claimed to be up to 120kW for 8 stalls. No mention of the charging standard or connector type.
