Powerline-based home networking technology is used for more than, well, networking the home.
It is also be used for networking the helping electric vehicle charging stations (EVCS) that are spreading as the popularity of electric cars increases.
G.hn chipmaker Xingtera and Star Charge, one of China’s leading operators of EVCSs, have completed trial runs of what they called “the first ever high-speed powerline communication (PLC) based EVCS networking solution.”
They used G.hn network technology.
Electric vehicle charging stations: increasingly a familiar sight
They said the success of their “EVConnect 2.0” field trials marks “an important milestone for the powerline communication technology as well as the EVCS market” and “the combination of “the wide-spread, real-world application of the G.hn powerline communication technology and the emerging, vast EVCS market makes it a profound achievement.”
Star Charge operates more than 20,000 charging stations in China.
US-based Xingtera makes chips, hardware and software.
In 2015 the two began to jointly work on the venture whose goal was to achieve higher-level intelligent operations of EVCS and enable value-add services such as commercial advertisement displays on a screen on top of the charging station.
The announcement is important for several reasons. It’s the first announced win for Xingtera, which joins Marvell in the HomeGrid Forum winners circle – although we suspect that Sigma Designs may have some unannounced wins.
If G.hn becomes the market share leader in the EVCS market, it will give G.hn developers the volumes to continue to improve the G.hn technology and reduce its production cost. On the other hand if HomePlug continues to dominate the EVCS market, it will remove a very large market opportunity for G.hn, the other large market being home networks which HomePlug currently dominates in powerline.
Xingtera calls its G.hn-based powerline networking platform “EVConnect” and designed it specifically for the EVCS market. It provides for payments, remote manage of the EVCS station and downloads videos to a screen on top of the charging station. Its XT1200 G.hn chip complies with the ITU-T’s G.hn standard for communicating over existing wires such as powerline, coax or telephone wire.
It said China Telecom is using G.hn for traditional home networking applications.
Know how boring it is to pump petrol into a vehicle? Charging an electric vehicle takes longer and is boring for an even longer period of time. The HD screens that EVConnect 1.0” supports at the charging stations use G.hn networking to download videos over the powerline to which they are connected. Xingtera said customers enthusiastically welcomed the commercials they watched while charging their vehicles.
Star Charge previously used a General Packet Radio Service (GPRS) mobile data service based on the 2G and 3G cellular system for mobile communications. It is also said to have considered HomePlug technology but decided to find a better communications technology.
Also enthusiastic was Ms. Shao Danwei, Star Charge chairwoman, who said, “The successful field trial of ‘EVConnect 2.0’ shows that the solution is now ready for adoption for our charging stations. Compared to all existing networking solutions, Xingtera’s solution has its unique advantages. For example, when we used GPRS modules to connect EVCS to the Internet, the communication was not…
