MCS connector generations
Based on piecing things together, there been approximately four versions of the MCS connector, so far:


 * 1) v1.0 Triangle, round pins + 1
 * 2) v2.0 Square, horizontal tuning fork + 3 extra pins (5 total)
 * 3) v2.4 Square, vertical tuning fork + 3 extra pins (5 total) (currently in Infobox)
 * 4) v3.0 Triangle, round pints + 5 extra pins (7 total)

 * Assuming the MCS connector follows the existing CCS signaling protocols, there are a minimum of five connections needed:
 * DC+
 * DC-
 * PE (protective earth or ground)
 * CP (control pilot)
 * PP (plug pilot)
 * Page 48 of this combined presentation shows a blurry sketch of "v2.4", which includes the three signal pins alongside the two power pins. Cheers, Mliu92 (talk) 14:49, 3 May 2022 (UTC)


 * Image at has the MCS 3.0 submitted connector.  How many pins do you reckon? `:-)` —Sladen (talk) 23:54, 10 May 2022 (UTC)


 * Coming full-circle, Ted Bohn has used images for ChaoJi and the v2.4 MCS connector from Wikipedia in the latest presentation from April 2022 at https://publicdownload.epri.com/PublicAttachmentDownload.svc/AttachmentId=78275 while providing some hints on the MCS 3.0 triangular connector using a higher-resolution version of the one posted to LinkedIn. I made a speculative sketch (matching the scale of other EV connectors) using some of the data provided. Cheers, Mliu92 (talk) 18:50, 8 June 2022 (UTC)


 * Ha, yes. First two images on Page 43 (Type 1/J1772, Tesla 02/NACS, Type 2/J3068) are pictures I took a few years ago, primarily for Wikipedia usage—good to see them being used, even by the people designing connectors!  —Sladen (talk) 10:30, 17 December 2022 (UTC)


 * The v2.4 MCS connector may have been based on a Tesla proposal, as photographs of the Megacharger connector; on the other hand, the Megacharger may have been based on the draft CharIN spec. Since Tesla is part of the CharIN consortium, I would assume the final Megacharger may conform to MCS. Cheers, Mliu92 (talk) 20:36, 3 November 2022 (UTC)


 * Relative size comparison of prototype MCS and CCS1 connectors. Cheers, Mliu92 (talk) 20:44, 3 November 2022 (UTC)

Tesla Megacharger and a mere children's toy
MCS capacity is four times more than the current 750kw implementation of the Tesla Megacharger, and even the V4, let alone V3 Tesla supercharger is limited to 250 kw, with 350 kw only possible with higher voltages, where V3 was expected to outdo CCS Electrify America's 350kw output per the mere children's toy tweet, unless that can be construed to entail only 400v capacity, where the supercharger exceeds CCS.

 * The V4 may do more if 800v charging is enabled. The first generation MCS stations are limited to 700kW as well, according to the documents of the German ministry which subsidizes the HoLA project. See the German wikipedia article for more. Guidod (talk) 22:30, 6 August 2023 (UTC)

Removal of Differential PLC from the specification
Differential PLC is no longer expected to form a part of the MCS ISO15118 specification. References to it should be removed. 154.47.106.44 (talk) 16:41, 14 November 2023 (UTC)
