Tesla Motors Shows Off China’s First Solar Supercharger With An Energy Storage System

At Auto China 2014, Tesla Motors took the opportunity to showcase its first solar Supercharger in Beijing

“At the recent delivery ceremony of Tesla’s first batch of Chinese orders in Beijing, two PV charging systems caught the eyes of the guests. The system was requested by Tesla Motors, and designed and manufactured by Hanergy Solar Group. Hanergy thin-film flexible PV system was Tesla’s first choice for the first PV Supercharger station in China.”

Though the solar Superchargers seen above are in Beijing, China, Tesla Motors opened a similar Supercharger site in Shanghai, China.

At the Model S delivery ceremony, Tesla Motors CEO Elon Musk commented:

“In the future, Tesla will work with partners to build supercharger network. The first charging station in Beijing was built in cooperation with Hanergy Solar Group. Tesla will continue to invest in the construction of superchargers in China, aiming to quickly expand the network.”

As for those solar carports/Supercharger, Hanergy Solar Group states:

“Hanergy Solar Group will deliver two solar carports, each in Beijing and Jiading, Shanghai. The Beijing carport, a mobile carport designed to be assembled and transported, adopts Hanergy’s GSE flexible thin-film solar modules. The Shanghai carport will be a fixed structure, and adopts Hanergy’s MiaSole CIGS high-efficiency modules. The first phase of both carports has been completed.”

But wait, there’s more in the work.  Musk says that Tesla is already in the process of building 7 Supercharger networks in China, all of which will be solar-powered units with energy storage systems..  They’ll be open 24 hours a day, 7 days a week.  The first of those networks will be in Beijing and Shanghai.

Back to Hanergy’s solar carports:

“The PV charging system by Hanergy Solar Group protects vehicles like ordinary carports while converting sunlight into electricity utilizing its designated rooftop. At the same time, the system charges the electric vehicle through its energy storage system. The system uses the CIGS thin-film PV technology, the most advanced in the world. With conversion rates peaking at 20.5%, this technology offers light weight, flexibility, excellent low-light performance and advanced packaging. More importantly, no fixed column is required, which significantly reduces the cost. The carport is mobile, beautiful, modern in appearance, and a perfectly integrated to city surroundings, providing convenient and fast charging services to electric car owners.”

Lastly, Ms. Zhang Qingliang, Vice President of Hanergy Global Solar Power and Application Group, stated:

“We are pleased to be the one to provide Tesla the first batch of solar powered Supercharging stations in China. As a technology-driven company, Hanergy has been actively exploring ways to utilize its thin-film photovoltaic technology to provide solutions through technological innovation and cross industrial integration. We have been working with multiple domestic and foreign automobile manufacturers to integrate solar, and is also researching on energy storage, photovoltaic car roof and other solar-automobile applications.”

China’s dependence upon coal for electricity is what convinced Tesla Motors that all Superchargers in China will rely on the power of the Sun and be supplemented by energy storage systems.

Can’t tell, but if 20 panels per car, the “.205” CF on (let’s be optimistic) 300watt X 20 would yield about 29.5kwh per day. Really, not bad. Does anyone want to guess how lossy the battery charge, discharge, charge would be?

China announced 58GW of nukes this week, including 8 more of the same AP1000’s that will be going online in a few months, in the City of Sanmen. This industry watches from this side of the planet because it’s the same Toshiba-Westinghouse design being built in Georgia, at Vogtle.

For slow C-rates (trickle charge from solar), round trip battery efficiency is really high, i.e. 90-95%. If the battery is big enough, it should have a pretty low discharge rate even at 135kW. High voltage DC-DC conversion can be 99% efficient when you’re not worried about space.

So I’m guessing 85-90% from solar panel to supercharger plug.

Interesting note about the China’s nukes.

No need to guess.
The Tesla S is around 85% efficient in charging:

And then the smog blocked the sunlight. 😉

I was wondering when that would be mentioned. Ironically, the last time I was in Beijing, we had two days of clear blue sky.

7 supercharger networks? Anyone who has more details on this?
Will there be one for diferent regions or cities or?

Or maybe it was just meant to be 7 supercharger stations and not networks.

What a useless solar crap. The panels aren’t directed to south and even partial shadowed by the neighboured building.

Yeah, hopefully they are using microinverters or DC optimizers that can work around the horrible partial shading issues that array is getting.

It’s great that they invest in clean energy too to make the cars actually run on green electricity.

Especially since they have been focusing their sales on the biggest coal burners on the planet with the US, China and Germany and soon Japan.
If that is any indication of anything then Poland, Australia and South Korea should expect to be “invaded” by Tesla soon.

This sounds to me like part of the deal to open China to Tesla. Now Chinese authorities can point to this ev network and vehicle as more proof that they are trying to do something about the horrendous particulate pollution there.
(So that they can tout their sponsorship of Tesla’s program in China). On Musk’s part he is all too eager to comply with the wishes of the Chinese, for look what happens when you don’t. Google for instance.
Anyway fortune cookie say: Things looking good for Tesla in China.

Storage at supercharging station is very important not only for storing solar electrons but also to level out the demand peaks. With storage, superchargers can be installed almost anywhere with normal and a lot cheaper 50–100 kW grid connection.
