New report stated that the cost of driving a mid size ICE car was cheaper than a mid size EV. Let the good times roll!
Ha! Nothing new about "shaft currents". Manifests as "brinelling" or "wash board" on race surface. Shaft is rotating in magnetic field after all. Electrically insulated bearing at one end breaks the circuit and stops the current flow thru bearings and attached equipment. SOP for big gennys. Or bypass bearing with shaft brushes? Gotta be careful to bypass BOTH ends of shaft, tho. Wind turbine design includes "static" drain also. Shaft currents can prove pita. LolHeh heh heh that'll send the EV"angelizers" bananas.
Here's a very funny (but completely logical) argument about the myth of saving money on EV's:
Warning: the presenter is Australian and typically irreverent so there'll be some language we wouldn't consider proper in a published video but I think it just adds to the authenticity . But he is a mechanical engineer and automotive journalist and so credibility is up there.
P.S. @idssteve's cars excluded of course but not all of us are skilled enough to engineer our own EV's
I didn't get through all 18 minutes of it. However, seems he's not outlining anything that isn't already outlined elsewhere in more efficient non video presentation format, in terms of the break even point for an EV being close to 10 years of required ownership/operation, at best. The video format of the discussion is basically just for dramatic effect, in my opinion, and actually probably a negative approach for trying to communicate with other than like supporters....Here's a very funny (but completely logical) argument about the myth of saving money on EV's:[ MEDIA=youtube]_VbDgBZTUWg[/MEDIA]..
the report I referenced was in the Wall Street Journal. It showed that with the cost of electricity going up and the surcharge many utilities place on home consumers that go over 1000 KW in a month. ICE look better and better.I didn't get through all 18 minutes of it.

This video is not what I based my statment on, it was WSJ report that broke out all the economics of the twoHa! Nothing new about "shaft currents".

Good to know. I'll look into fabbing insulated sleeve for outer race of bearings in mine. Or explore ceramic bearings? Hard to believe that was missed. Pretty amateurish imo. Ug.
With shaft currents floating around, I might expect need to protect liquid cooling circuits from "electrolysis erosion"? Maybe include sacrificial anodes?
Understood. Not finding a link to a WSJ report in ur post, on my end?This video is not what I based my statment on, it was WSJ report that broke out all the economics of the two

The WSJ cannot be linked as they now will require a paid subscription, something new. On another note a Tesla S on the Highway went poof, no reason just poof.Understood. Not finding a link to a WSJ report in ur post, on my end?
I read MUCH faster than I suffer patience to watch vids. Overheard this one. Coworker in break room. The guy's description of bearing failure caught my ear. Much issue with that on a LOT of our equipment. Absent pretty elementary precautions. Imo.
If designers are THAT steep in learning curve,... Pretty precarious prediction precision ? Lmao
Still, I'd like to read the WSJ report you're talking about? If you'd post it? Lol
I put rings in my daughter's 2005 Prius a few years back. It started burning enough lube oil to plug catalyst. VERRRrry expensive catalyst. Lol. The wife's 2005 "EV mode" Prius virtually never runs its ICE. When it does, the poor thing might start and hit full bore high speed in seconds. NO warm up! Cold oil, cold cylinder walls, cold rings, cold OIL rings... Lol. Also cold catalyst, btw. Lol.Cost of EV use must include service life expectations and replacement costs of battery? Which WSJ report is OP referencing?
I know Prius NiMH crowding 20yrs that suffer no discernable degradations. A proprietary Toyota special sauce? Combined with essentially 60% SOC limits? LiPo in our handsets certainly indicate shorter service life. Possibly due to routinely exceeding 80% SOC?
And then what labor costs of swapping an embedded batt? MANY batts failed in my old Bolds over a decade +. Ten second swap and back to work. Abject nightmare replacing swelled batt in my K2. Poorly soldered connector pulled from board. Still languishes in my "Round TUIT" collection. Lol.
I realize that Tesla canned cell config can prove more durable than mobile envelope. Less delamination failure? What ARE forecasts for EV LiIon? Based on what criteria? Wandering minds wonder. Lol.

I simply didn't find the video useful since it presented facts that one can already otherwise read on one's own, via a faster and more credible presentation method than having to sit through that 18 minute video. For me (in my opinion), the video purpose seems more about appealling to those that would already like and support the positions and mannerisms the video presents, basically almost a rallying call of likewise positions/supporters/opinions probably for the purpose of maximizing YouTube subscribers/views and monetizing/advertising.Well, I'm not sure what you not going through all of it has anything to do with it?
I'm also not sure what the format has to do with it. Americans own their cars for an average of 8-10 years so STCo's point is still valid and more importantly, based on facts, regardless of which article is quoted.
The funny thing about facts is that you don't have to like them, they stand on their own regardless of the number of "like supporters" .
Perhaps if you disagree with the OP, you can proffer a different point of view with some facts so that we can all have fun instead of criticizing the medium of delivery and the deliverer .
Entertaining or irritating, I personally learned a couple things while over hearing the guy. I'd not heard or read of shaft current bearing failures in EV. Assumed the potential but also assumed diligent engineering to have anticipated and mitigated. It's not like freq drives haven't been around for a few decades. Lol.I simply didn't find the video useful since it presented facts that one can already otherwise read on one's own, via a faster and more credible presentation method than having to sit through that 18 minute video.

I don't disagree with the general opinion that EVs probably take too long for return on investment and lots of otherwise presented arguments are questionable. Whenever I've posted about if an EV would be for me, the position from me has been.... no certainly not now maybe later if things evolve a bit more/better.... However, that video isn't going to do anything (in my opinion) to convince those that would argue otherwise.
For what it's worth, the guy likes EV's, his only point is that the economic argument isn't there (yet?) which was STCo's point. He's got videos in support of EV's where the use case stacks up.I simply didn't find the video useful since it presented facts that one can already otherwise read on one's own, via a faster and more credible presentation method than having to sit through that 18 minute video.

To convince, or not to convince, is that the question? Lol. Can ANY one be convinced atp? Nothing new about political, economic, etc exploitation. Comic expression frequently proves comic release for frustration of perceived disenfranchisement?I simply didn't find the video useful since it presented facts that one can already otherwise read on one's own, via a faster and more credible presentation method than having to sit through that 18 minute video.

Scary. I wonder for comparison how many ICE cars went poof in the early 1900's when they were new as well. I can't find any information on this.The WSJ cannot be linked as they now will require a paid subscription, something new. On another note a Tesla S on the Highway went poof, no reason just poof.
