Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

NAWA looks like another hopes and dreams company. .... Sorry it all looks like hype to me. You may well be completely correct, and likely are, reading your investigations. But as I said, I haven't had time to track their claims and some did seem unreasonable. The part that caught my attention big t...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

.... Did you find any product specs that would allow one to calculate watt-hours per litre? Like I said, I haven't scrutinized it all in detail BUT they are very clear that it IS a lithium cell WITH an embedded supercap, which is what I have been working on for a while. Having the supercap embedded...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

I think that horse has been beaten to death enough :-) Not getting up in this lifetime ... Came across this yesterday, and a cursory search shows great promise. I have been experimenting with an embedded supercap idea for ages, so the bastids beat me to it :-) The 5X more powerful needs to be scruti...

Missed that .. what confused me is that this seems to be a "new" post that popped up, as the Jan 2016 is still there, and both have Jan 2016 dates ???

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

They posted internal pix of their "supercaps" on F/Book - https://www.facebook.com/kilowattlabs/p ... =3&theater
Odd that they copied these from a previous post they did on 26 Jan 2016, over 2 yrs earlier ! So many more questions :-)

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

... But I asked GridEdge several questions per email, so far the silence is deafening. 100 watt to run them on standby and 14 hours to heat them up before they are usable? .. In contrast the supercap is very new, exorbitant claims .... Yes. Having seen the unit, plus it's build quality (excellent),...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

I went to the presentation last night. It was more about ARVIO's business of manufacturing /supplying storage systems than the supercaps. I think their products are top notch, irrespective of the battery . I wanted to go, but had an ATA meeting at the same time. Guess we'll have to wait and see if ...

Re: Stray Capacitance

Hiya, Yes it is definitely a capacitance issue. I seen it a lot, especially with Formula SAE-E builds (Universities), plus my own battery packs. Because the HV section must be isolated, usually with differential "earth leakage" to vehicle 0V, there is no point "earthing" the Al case to the vehicle c...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Hi folks (Vic AEVA here) They have a presentation here tomorrow, just up the road - Is it worth going? or is the horse beaten enough ? https://www.eventbrite.com.au/e/home-battery-storage-revolution-registration-41801353975?aff=efbevent I already went to one last week on Sodium nickel chloride batte...
