Finally a video showing that axial flux motors serpentine the magnetic field between the external magnetic rotors … offset between the magnetic field conductive material pads that are not permanent magnets. Truly brilliant design.

From Australia to Vietnam, the Iran war is fuelling demand for EVs | Economy News | Al Jazeera

Ever since the Gen II Prius, when fuel prices went up? So too - fuel efficient vehicle demands . At the time - the only choices were between Honda & Toyota hybrids. With Middle East Dynamics, hear the world is again. Only now there are hybrids, plug-in hybrids and full EVs.

Surprisingly, & even though our plug-in minivan typically gets 60 & 70mpg - the better ½ asked whether we might move back into another (our 3rd) Tesla (or some other ev?)

Anybody else considering making the full Ev jump?

I was worried about this. Iran did manage to hit the Shell Pearl GTL base-oil facility in Qatar, which is one of Shell’s crown jewels and has been in production since 2011–2012. GTL (gas to liquids) is a Group III synthetic base oil derived from natural gas via the Fischer–Tropsch process and is used in most synthetic motor oils today. Expect oil changes to become more expensive. It could be hard to find synthetic motor oil as well, especially those with specific OEM certifications, such as those for European cars. Most synthetic Shell motor oils (such as Pennzoil) use a GTL base oil.

• There are "fillers" between cells that are endothermic, heat absorbing. This reduces the risk of a complete pack event.
• There are "separators" within the cells that upon heating, block ion transfer, turning off energy release by the cell.
• As for relative risks:
  • NMC/NCA - heat and fire
  • LFP - toxic gas with a lot of explosive hydrogen

I am leaning towards battery pack safety regulation that incorporates both the "filler" around the cells and "separators" within the cells. Not something that needs to be done instantly and should not specific the specific media. Rather, a performance based, benchmarked solution.

Very impressed with Lucid Gravity designs. Pricey but very nice. With adjustable suspensions for off-roading. If only they have solid states, lfp or sodum ions. Still on lithium ions.

There are other flammables such as plastics that also burn.

Here I am wearing my NexPowerEnergy shirt and hat. I wanted to let you know of this impressive 12-volt battery for sale at SaltyHybrid.com. It costs $175 and allows you to control the battery management system for it with a phone app: http://www.saltyhybrid.com/collections/all-products/products/the-ultimate-12v-battery

This would be ideal for those who use their Prius to power their home during a power outage because it will give you valuable data about how your system is functioning, as well as allow you to change charge settings/thresholds.

This battery is also ideal if you live in super extreme cold weather and extreme hot weather because sodium battery chemistry is superior to standard 12v chemistry in extreme temperatures.

Another valuable feature is it has a power...

Saw this on Bogleheads today, but the mods blocked comment-.

Apparently Toyota is worried about the upheaval in the auto space, in particular competition from Chinese EVs. In response, Toyota is saying that its suppliers have to increase productivity (reduce costs) and can relax requirements to maintain spare part availability.

I would think Toyota is OK with hybrids in USA, in other words, I am looking for a motive in this, Might be they do not like US tariffs. Also I know Scotty Kilmer on YouTube thinks quality is down, maybe Toyota is saying get used to it.

If they have a "Full Self Driving" feature, I would be interested provided the rest of the specs are equal to my 2019 Model 3.

A computer controlled, two-stroke engine with integral generator could provide either emergency charging or range extension for EVs:


As my ultimately unreplaceable Tesla battery ages, it becomes more attractive to have a lightweight trailer with a 25 kW, flex-fuel, generator. Of course this assumes available and affordable fuel.

Finally, the Gen 6 RAV4 PHEV, the PHEV version of Toyota’s first take on a software-defined vehicle (SDV), will start hitting dealer lots next month, in April. It is also the first Toyota to feature TSS 4.0, which will be further upgradeable through over-the-air software updates.

It is over $3,000 cheaper than the Gen 5 RAV4 PHEV. It looks like Toyota has finally figured out how to make EV batteries that aren't astronomically expensive.

NPR: How long do electric vehicle batteries actually last?

... As the fleet of EVs on the road ages, new data pooled from tens of thousands of vehicles is showing those batteries are lasting longer than expected. ...

At auto auctions, a lot of healthy batteries
... "We were expecting battery health to be experiencing mass degradation over the first one to three years of owning a vehicle," George says. "What we have seen, though, is that these 2, 3, 4-year-old off-lease cars that are coming back have battery health scores well upwards of 95%."

Recurrent's data also shows that cars from most major brands retain 95% or more of their expected range after 3 years, thanks in part to software and...

I just ran into this car while surfing. Apparently this car has been around for a while. I'm only referencing this because of the recent demise of the Toyota Mirai - mainly the lost of convenient hydrogen stations. Thank you again Shell oil.....

Don't know how well they'll sell, if you can't refuel it.

Experimental Program in Massachusetts to start using EVs to support the grid when production is down. "Bi-directional EV chargers will turn vehicles into energy storage assets, advancing grid reliability and lowering energy costs for customers." Article doesn't seem to say what happens if you come outside to go to work and your car's been too busy supporting the grid to have charged itself up. Lots of details to be worked out, concept is good though.
