Talk:Capacitor electric vehicle

Multiple Issues
I got here from Ultrabattery which used to link to Electric double-layer capacitor, but itself had a circular link. I then realised that this article has more information on UltraBatteries, changed the redirection here instead.

The next bit of delving (a web search) gave no obvious hits for Capa vehicle (outwith Wikipedia) for capacitor based vehicles, as opposed to Certified Automotive Parts Association vehicles. So I wondered if the term was made up (WP:MADEUP).

I suspect that it was, and that checking the edit history, it was moved soon after creation from Capabus, which appears to be a trade name. Further delving, and I note that it was changed from a redirect by, who did most of the editing, along with , both of whom are blocked along with (who created the Ultrabattery and UltraBattery redirect pages) -- see Sockpuppet investigations/Mac/Archive.

So I saw there were easily enough problems with the article for a tag, but I found it difficult to narrow down the areas to a handful. I'm sure there's something useful here, but it can probably be merged with electric vehicle. Tim PF (talk) 22:56, 23 March 2011 (UTC)


 * Ok, so I shouldn't have left in -- that was a mistake, probably due to confusion with the Ultrabattery redirects. Tim PF (talk) 23:51, 23 March 2011 (UTC)

Going forward with this article
I did not verify the whole article, but the subject exists and is most certainly not a hoax. Please use cleanup tags only where there they are needed; we could tag all of Wikipedia with "expert", "cleanup", and of course "incomplete" (and we would be correct for most articles), but that does not mean we should.

Most examples described in this article are actually hybrids that store energy when braking and use it later for acceleration (per the article intro: "uses supercapacitors (also called ultracapacitors) to store electricity"). These examples could conceivably be merged into hybrid electric vehicle, whereas the Capabus could be merged into electric vehicle. Considering, among other things, the lengths of these articles, I'd prefer keeping a separate article on the use of capacitors for driving vehicles. As for the name, "Capa vehicle" does not seem to be an established term, so a descriptive title would arguably be a better choice. Rl (talk) 09:20, 3 June 2011 (UTC)


 * Okay, but did you also note the Multiple Issues section above?
 * I agree that it doesn't help to mix both hybrid electric vehicles and short-range electric vehicles into one article like this. I'm not sure of an easy descriptive title, but it doesn't help that both Supercapacitor and Ultracapacitor both end up at Electric double-layer capacitor, which has a Vehicles section, which points back here, and largely duplicates much of this anyway.
 * BTW, I'm glad someone else is looking at this article now. Tim PF (talk) 12:00, 3 June 2011 (UTC)

Article title
"Capa vehicle" is a horrible neologism not used outside Wikipedia - would Electric double-layer capacitor vehicle or Ultracapacitor vehicle be better? Fences &amp;  Windows  07:21, 19 June 2011 (UTC)


 * The "hoax" is the term "capa vehicle". It looks like the article was started by a now-blocked user as "Capabus", and then he decided to expand its scope to cover other vehicles which use ultracapacitors, and so coined the current term "capa vehicle".
 * Whilst there are plenty of sources for the use or proposed use of ultracapacitors in vehicles, these currently only extend for a couple of miles (perhaps 2% of a battery vehicle's range), and are either by using regular intermittent very-fast charging, or else as a RESS in a hybrid vehicle, which latter does not a capa vehicle make.
 * In other words, the original "capabus" article has been padded out with bits which really belong elsewhere, mostly either in hybrid vehicle or electric double-layer capacitor, to end up with something of a dog's breakfast.
 * I'm not saying that there isn't scope for an article which includes all usages of ELDCs in vehicles (both road and rail), but I can't see how it would work without including bits that duplicate things that belong better in other articles. Tim PF (talk) 21:27, 19 June 2011 (UTC)
 * In the spirit of WP:BOLD I have moved the page to "capacitor electric vehicle" to align with the title of battery electric vehicle Alx xlA (talk) 02:17, 30 August 2021 (UTC)
