The potential to significantly reduce pollution could be huge.

Toyota boasts new battery technology with 745-mile range and 10-minute charging time — here’s how it may impact mass EV adoption::The potential to significantly reduce pollution could be huge.

      What certification does it need other than be certified by Toyota for use?

      Engineer in the automotive industry here. Vehicles need a ton of certification by tons of different governments and face very strict regulation.

      Just a battery alone is going to be subject to lots of EMC emissions and interference tests. Then you have the capability to survive crashes, fail operational requirements, how does the battery fail (does it explode or just disconnect itself?), etc. etc. These are all dependent on the chassis the battery is in, so they can’t just swap it into an existing chassis and say “Oh it worked with battery A, it’ll work with battery B.” Unfortunately the requirements are just way too strict for that.

      Additionally I can’t go into details but the sentiment others are echoing of “If it’s coming in 2028 they should have a functioning prototype” are true in my experience. It takes several years to design and release a car, and when you’re introducing a new battery tech or drive train or similar changes it takes even longer.

          Different battery chemistries do not behave identically in terms of failure modes, EMC emissions and interference response, and tons of other things. Just swapping one battery for another has a huge effect even before you consider auxiliary components like charging circuitry.

          My assumptions as to why you can just drop in an aftermarket battery and crate motor into an existing ICE vehicle (also, far from any vehicle, it is a relatively niche product) are that A. The batteries are way smaller and aren’t structural to the frame the way they are in BEV-first designs (but this is how we get good range out of them). B. The companies selling these probably aren’t held to the same emissions standards that an automaker is.

          Again, these are assumptions, I don’t work in conversions but in BEV designs primarily. I know there’s a ton of red tape for us to even think about changing battery chemistry, and we 100% would have to get all new certifications for it.

              12V sealed lead-acid batteries are a standard size and chemistry… They are absolutely not comparable to a BEV battery. The lithium ion 12V batteries are built to the emissions standards and regulations of the 12V lead acid, that’s a known quantity and a hell of a lot less energy. BEV batteries contain kwH of energy, they are significantly larger, are a nonstandard size on every single vehicle. Even if Toyota made it the same size and shape, the energy density might be enough to fail EMC regulations (without having to change the size and shape)

              I don’t know what else to tell you man, I work on electric vehicles for my job. Literally an engineer. You can choose to not believe me but it just isn’t anywhere near as simple as you’re acting like it is. Just because you think it’s like swapping an alkaline AA for a NiZn AA doesn’t make it true.

      Then Toyota has some magic power that all the other car companies I work with don’t

      I know Tesla plays fast and loose with NHTSA regulations, but I doubt Toyota will

      This battery technology will have to pass safety inspections, just as Li-ion

          If they had the ability to test it in a vehicle, they would be shouting about it from the hills rather than this “maybe it might be possible” report that keeps getting shared

          It would be magic to get it into a vehicle in 2028. Every other car manufacturer has finalized their designs past that by now, and aren’t going to risk such a massive change this late in the design process

          This is part of why the infotainment systems in cars tend to suck. They’re finalized about 6 years before the car goes to market

              I don’t know how else to explain to you that you have to have a street legal vehicle to sell from the factory.

              You’re welcome to mod your car, and you probably won’t have issues, but that’s not how it works for new vehicles

              The 2022-2027 model year of one of the biggest manufacturers is using a chipset from a phone from 2016 in their infotainment. Yeah, you’ll get some minor updates, but they’ve recently cancelled any more major updates since the chip is dead. And it’ll still go into cars until the next unit they designed last year enters production in 2028

                  Because an infotainment system isn’t considered safety critical…

                  Once they pass safety tests for this new battery, which will take many years, there might be an option for an after market modification, but as the other engineer in this thread tried to tell you, it’s kind of unlikely
