EVs and the technologies that they encompass are disruptive technologies. If you're not aware of what that term means check out this presentation:

The coming transition away from ICEVs towards EVs is evangelism so much as economic logic, and China is using its financial and totalitarian might to accelerate that process. Legacy vehicle manufacture is already struggling to compete with the onslaught of EV introduction and that competition will only increase in the coming years.

I can't say there was any real value in that video. There were better ways to have used the time spent watching it.

I don't see s EV technology or the technology they encompass as being disruptive, I'd say more evolutionary. They don't change the way we travel they just change the motive energy.

You miss the point completely. EVs are not just a replacement for fossil fuel powered vehicles. They are internet connected, can be used to power your house, or just charge worksite tools, and they have an incredible synergy with home based generation such as solar. The degree to which they are able to change the way we currently travel, communicate, power our lives and impact our environment is revolutionary, which is just another way of saying disruptive. "Travelling" is just a small part of what EVs are capable of. Jim Farley CEO of Ford has recognised this:

50 or 60 years ago my uncles old Massey Ferguson 35 could power the cow shed when the power went off. Vehicles providing power for household or industrial equipment isn't new, and it didn't need internet to be able to to do it either. 👍

Why do you need to connect to the internet to provide power? My car has V2L, and doesn't connect to the internet in any way. I'd actually prefer not to have OTA, if having it also means the whole car can be disabled at the whim of the manufacturer.

People often mistake me for an adult because of my age.

Keep calm, and carry on posting.

All of it adds to the cost of the vehicle and almost none of it is standard on all models. No marque has the necessary relationships to make it all worthwhile.

Tesla comes closest yet after all this time the only vehicle with it all is CyberTruck - and only a tiny percentage of owners will be using it for that purpose.

Don't get me wrong it's all perfectly good and proven technology - problem is availability and integration. Mostly a chicken egg problem where no single company owns both a chicken and an egg. Although Tesla comes close to that, the CyberTruck was not the right vehicle to deliver it to the U.S market let alone anywhere else..

You don't need internet connectivity to provide power that's just an assumed correlation. Due to its online connectivity I know where my Polestar2 is at any given time which is very useful if anybody was clever enough to steal it but also the positional data means that I'm aware of traffic congestion or road closures in advance. I can also remotely check on its state of charge and whether it's locked, and I'm able to control its climate control functions. It's also nice to be able to upload apps to the car for the likes of Youtube viewing or other online functions. And of course I'm always running the most up to date OS with OTA updates.

In answer to the following post in this thread most EVs currently in NZ can be used in a V2H or V2G capacity with the right home set-up. Sigenergy's battery stack set-up with integrated 25 kW EV charger can access most EV's batteries now. The rapid introduction of bidirectional EVSE's will soon make this function available to most EV owners, albeit for an extra investment cost.

I'm interested in V2G for the V2H aspect for power during power cuts. Googling around NZ it's difficult to find out what equipment is available and what the cost might be. I see there have been a few trials here and there. I'm with Vector if that makes any difference.

I'm not currently looking at solar, just vehicle to home during power outages. My understanding is the lines company needs to approve it. Any idea what that kind of system costs to purchase and install?

Future proofing.with solar capability would be nice maybe not essential if it adds to the cost.

Oh, is it "Toyota will bring solid state batteries to the market real soon now" time of the month again?

Time of the month? They have been bleating about it for nearly a decade and still no show.

Toyota is one of the top company spenders on lobbying for the oil industry - was in the world top 3 at one point.

They also the second or third most indebted company on the planet.

People bleated about BEVs for decades yet here we are.

Solid state battery infrastructure build is under way. Working prototypes exist. Not sure why people are bleating negatively about it.

The article indicates completion in 2027/2028. It's some indication that Toyota see solid state as mature and ready for volume manufacturing soonish. There is no indication how much volume that plant will produce.

It's clearly not enough for all Toyota vehicle production.

Likewise it's not clear what Toyota will do with it. It's possible they will use this tech in hybrid rather than using it for 1000km pure ev. Heavy transport is another possibility. Either way it's almost certain Toyota will pilot this technology in China market first before other markets. Bz4x remains relatively low production at this time.

Reading the transcript of the question asked at their share holders meeting it appears they are "hopeful" they will meet this date. They have been touting SS since 2009.

Slightly off topic, that roof is a framing, weatherproofing nightmare let alone not optimised for solar. But kudos for their investment in the new tech.
