Cap-xx Share Discussion Threads

A supercapacitor is a capacitor you complete and utter fool.

It's like saying a Veyron isn't a car.

What date was that?. Think they tried a supercapacitor on a racing car but didn't work.

Are you aware then that Cap-xx don't actually manufacture capacitors?

Toyota has revealed the full powertrain details of the Yaris Hybrid-R concept that it teased a few weeks ago. The intriguing concept uses a 420-hp 4WD driveline that's derived from racing. In an interesting twist, Toyota uses a combination of super capacitor and motor-generator, in place of the battery pack that typically powers the motors in contemporary hybrids.

Hahahahaha,

This dude doesn't quit.

You see, your argument there is a non sequitur (something else for you to look up). Because I asked you to state the difference between a capacitor and a supercapacitor doesn't mean I don't know what the technical difference is. And the Wiki link I gave you explains it quite clearly.

Now you've made yourself look like a complete tit, I suggest you let the adults get on with their discussion.

So you actually believe there is no difference between a supercapacitor and a capacitor lol.

So tell me what EV car supercapacitors are used in. I can tell you now they are certainly not in a Tesla and they are certainly not used for regenerative braking.

[mauricemonkey] 12/2/2021 13:48

"I will tell you again, Cap-xx don't manufacture capacitors."

FML.

Graham, explain to me the difference between a "capacitor" and a "supercapacitor". Use the Wikipedia link I gave you as a starting point.

Why did the RADAR system I worked on had capacitors the size of waste paper bins. Do you think they would've have used these massive components if a smaller version had been available?

[charlesjames1] 12/2/2021 13:47

Graham is out of bed I see. I mean you are on filter and really have zero idea of engineering, but out of bed you are.

[mauricemonkey] 12/2/2021 13:46

Look, doofus, they're used all over the place. In all sorts of applications.

You seem to be stuck on the fact of supercapacitors being used as an energy store. Get your thick head around the fact they're used for all sorts of uses in high power electronics, not just as an energy store.

Go choke:



"Supercapacitors are used in applications requiring many rapid charge/discharge cycles, rather than long-term compact energy storage — in automobiles, buses, trains, cranes and elevators, where they are used for regenerative braking, short-term energy storage, or burst-mode power delivery".

Get a small clue about electronics, then come back to us.

[grahamwales] 12/2/2021 13:43

I will tell you again, Cap-xx don't manufacture capacitors.

[grahamwales] 12/2/2021 13:42

"How many supercapacitors are currently in EVs - Millions." Really do you have any proof of this or is it just a throwaway comment.

I ask again can you provide proof of your comment regarding millions of supercapacitors in EV's.

[mauricemonkey] 12/2/2021 13:33

Lol, go look up the "Dunning-Kruger effect". You're clearly way out of your depth in this discussion.

You quite obviously don't have any clue what capacitors are used for.

[grahamwales] 12/2/2021 13:32

Maurice.

"How many supercapacitors are currently in EVs - Millions." Really do you have any proof of this or is it just a throwaway comment.

Yes supercapacitor technology will filter through into batteries, however CPX wont be in that market and the why EV's won't need supercapacitors now or in the future.

Yes there will be a market for them but only for their size. Small gadgets and wearables perhaps.

There are lots of other companies competing in the same area though.

Cap-xx is by their own admission a development company, however they have not developed anything new for a number of years now.

[mauricemonkey] 12/2/2021 11:30

Hahaha,

You totally ducked the question. Son, I used to work on RADAR systems that pumped out 1MW of RF energy that could find an object with the RCS of a cricket ball at 100 miles. We had capacitors the size of waste paper bins. If you want to talk about power electronics, I'm up for that.

So, I ask again, what is the difference, in respect of power electronics, between a capacitor and a "supercapacitor".

I ask these questions because you asked/stated:

"How do you see supercapacitors helping out the automotive industry?

How many supercapacitors are currently in EV’s.

Batteries are slowly catching up supercapacitor qualities"

Which I already answered.

But for the record - supercapacitors are required in power electronics to assist delivery of short bursts of high power and to act as part of electronic filters to stop rogue frequencies interfering with the operation of the car. They also assist with power generation and dissipation (that's thermal management son).

How many supercapacitors are currently in EVs - Millions.

Batteries are slowly catching up supercapacitor qualities. Only in terms of energy density, but that is not all capacitors (super or otherwise) do.

Wow getting a bit edgy there Maurice, what’s the matter am I showing you up for your lack of knowledge about Cap-xx and what they manufacture.

I’m sure you are well aware of the difference if not then you really should not be investing in companies you know nothing about.

But then again as I said earlier it’s your money to do what you want.

[mauricemonkey] 11/2/2021 21:12

F me, this dude doesn't quit. Gets smashed to bits and keeps coming back for more.

Tell me, oh great one (that's you Graham), what's the difference between a capacitor and a "supercapacitor".

Please focus you answer on their respective uses in power electronics.

[grahamwales] 11/2/2021 20:40

Maurice

I take it you know the difference between capacitors and supercapacitors. Cap-xx don’t manufacture capacitors.

[grahamwales] 11/2/2021 18:49

Charles. Supercapacitors have been around for years and achieved no real progress unlike batteries. Never say never.

[globalwill] 11/2/2021 18:49

The guy is a serial basher of this share and has been for years. Reminds me of Openspaces on LSE. Definitely has a motive.

[grahamwales] 11/2/2021 18:48

Richsydenham. So you drove for 4 hours and you had to stop for electric. If you had driven a petrol or diesel car for 4 hours would you have not stopped for fuel.

I drive a Tesla and if I’m doing long journeys I plan my trip to stop at Tesla Superchargers. Yes it takes longer but to be honest stopping for 30 minutes to have a coffee is a great way to relax after fill up after a long journey.

[charlesjames1] 11/2/2021 17:18

From someone who has a Masters Degree in Electrical Engineering I can categorically tell you that batteries will not be replacing capacitors. And people listen to this person. Strewth.

[richsydenham] 11/2/2021 14:51

I drove a tesla for 6 months last year. Frankly I was very dissapointed in the range and the charging speed. If you are deiving short distances all the time its great but if you have to drive a 2 hr return trip you have to stop. The range it tells you is around 10-20% wrong so you have to calculate yourself if you will make your destination. The charging is super fast for 10 mins or so but the very slow. Oh and if it rains then knock off another 10% off the range
