IEC 63110-1 Committee Draft for Vote Draws Near

Please read on to discover the latest news from the smoke filled back offices of the International Electrotechnical Commission’s (IEC for short) electric vehicle standards development committees.

Here once again is the roadmap for the development of the IEC 63110 international standard defining a protocol for the management of electric vehicles charging and discharging infrastructures:

2018-01-IEC-63110-Roadmap

Part 1 of the standard (IEC 63110-1 for short) concerns itself with potential EV charging and discharging use cases. As we have previously mentioned the committee produced a draft document for comment many months ago. The original draft has now been modified to incorporate the suggestions contained in several hundred comments received from around the world. A grand total of zero of those comments emanated from the United Kingdom. The committee is issuing one final call for informal suggestions for further vehicle-to-grid use cases before their next face to face meeting which will be held in Seoul, South Korea starting on June 18th 2019. At that meeting the Committee Draft for Vote (CDV) document for 63110-1 will be finalised, following which the assorted national committees that make up the IEC will vote on the committee’s proposals.

Meanwhile the IEC 63110 part 2 (IEC 63110-2) task force looking into possible options for “message encoding and transmission technology” to be included in the standard are also currently completing their work. It was agreed on the IEC Technical Committee 69 Joint Working Group 11 (TC 69/JWG 11 PT1 and PT2 web conference calls earlier this week that the Seoul meeting should be extended by a day in order to finalise this aspect of part 2 of the standard. By way of example, version 2 of the Open Charge Point Protocol (OCPP 2.0) specifies using JSON encoding over RFC 6455 WebSockets transport, but the task force have been considering a wide range of other possibilities.

Should you have any thoughts on these thorny eMobility topics then please do not hesitate to get in touch at your earliest convenience. After the TC 69/JWG 11 meeting in Seoul these matters will be starting to be set in stone (SSS for short).

Tesla Files SaMDES Patent Application

Regular readers with long memories may recall that way back when in November 2017 we here at V2G UK announced the launch of our Static and Mobile Distributed Energy Storage project? Those readers can no doubt imagine my surprise when I recently discovered an article by Sebastian Blanco in Forbes magazine announcing that:

There’s the grid, the evolving smart grid and then there’s no grid at all. That’s the paradigm that Tesla is exploring in a new patent application, Number 16/186390, which calls for controlling energy generation interactions (solar roofs, anyone? ) that bypass the electric grid.

Here’s the monochrome graphic that Sebastian extracted from Tesla’s recent microgrid patent application:

To my way of thinking that’s remarkably similar to the left and central portions of the much more colourful “prior art” in the banner that’s been proudly displayed at the top of every page on this web site for many years now. Do you suppose that Elon Musk is an avid reader of the V2G UK web site? If so perhaps he first arrived here way back in 2014 when I took Tesla’s marketing mavens to task over their propensity to be “economical with the truth” concerning open source electric vehicles.

Tesla’s recent US patent application includes the following paragraph:

This application is a continuation application of U.S. patent application Ser. No. 15/153,037 entitled “ENERGY GENERATION INTERACTIONS BYPASSING THE GRID,” filed on May 12, 2016, which is herein incorporated by reference in its entirety for all purposes.

That seems to refer to this 2018 patent assigned to “SolarCity Corporation, San Mateo, CA”. Does the US patent office by any chance have a number to call to advise them of occurrences of “patenting the bleedin’ obvious”?
