VW Solid State Battery

I’m happy that my QS shares are going up!

I love hearing news like this - solid state batteries really will revolutionize the EV industry and I’m excited to see it!

This VW ID.2 interior is copy / paste Mach-E. Glad they decided to at least slap a VW badge on the steering wheel.

Not sure how optimistic to be on this. The sub-headline and final sentence of the article tell the whole story.

For sure. That is pretty much a challenge with every new thing.

For sure. What bugs me about this particular topic is that there are many articles/headlines that imply solid state batteries are right around the corner when they really have no idea if or when they will be able to be mass produced affordably. My concern is that there are people considering an EV that are holding off for solid state.

I see some brownouts in my future.

Multiply the pack size (in kWh) by 12/h to get the wattage pulled down during a 5 minute charge! 100kWh pack would pull 1.2 megawatts.

That'd be quite a large conductor for going back to the future. Even at 1.2 MW we're talking 1500 amps for an 800 Volt battery. See https://en.wikipedia.org/wiki/Megawatt_Charging_System for something in that ballpark.

I am tired of waiting for this. When they can put a 180 kWh battery in a MME, then I will be interested.

sorry... just like fuel cells, solid state batteries are mostly "science projects" at the minute... yes they can work, but not in the messy real world. "soon"... think 5-10 more years to figure out production at scale.

Keep in mind we are nearly 50 years into the dev cycle of current Lithium batteries. They were invented in 1976.

chargers will be as plentiful as gas stations way before that ever happens.

I hate public charging. I hope you are wrong, and I am willing to bet you a beer on it! We will never need as many chargers as we have gas stations.

Of course I don't have a lot of faith we will get high capacity batteries any time soon either, but WTH. Are you in?

Each conductor, according to the Megawatt Charging System standard, would be 1 inch in diameter, or 11/0 American wire gauge. That's one heavy charging cable.

Nah, I would be more interested in a 90 kWh that weighs half as much.

But clearly VW nor Ford nor Toyota nor anyone else is anywhere close to mass producing a battery for cars.

My guess is this “prototype” is the same as everyone else…… big enough to fit in a wristwatch.

No surprise they’re focusing on consumer electronics instead of cars. The article shouldn’t have even mentioned VW.
