Improved Battery Tech from BMW

[Mikehig]

According to Autocar, BMW are making significant strides with their battery technology: greater energy density; faster charging; lighter; cheaper to build. Due on the market in 2025:

Items like this make me wonder whether it would be useful to have a "News & Stuff" thread on this forum?
It would let folk post news snippets and other stuff which may be of interest but don't really merit a thread of their own.

I love the wording that the range is increased by 30%, but won't go over 620 mile and it's good to hear BMWs will get round batteries

Not entirely sure just what 'technology' BMW have? They don't make cells but buy them in and they work with research companies rather than doing the research. As far as I'm aware all BMW do is build the battery packs?

Isn't this planned 2025 improvement just when CATL hope to be supplying solid state cells in their race against Toyota?

Personally, I think commercially viable solid state batteries will be really interesting even if cars rely on a much larger traditional Li battery behind it.

Being smaller and lighter is good but the faster recharge and release times should apparently make regen more efficient plus, banging in top up charges much quicker. Could also be a game changer for small city cars and hybrid EV ranges.

Yes indeed. It's the natural evolution of the technology. It's not really news to hear that manufacturer's are working towards battery tech improving over the next few years.

Maybe this link helps suggesting the BMW are moving to CATL

There's a lot of hype at the moment about SS but that's because a lot of the firms doing research have been fund raising over the last 18 months.

But, if they do finally get the production breakthroughs they're aiming for over the next couple of years then by 2035 the EV landscape will look quite different to today.

I suspect the the current production date of 2025 is more than a bit bullish but firms seem closer today than ever before.

I wonder if BMW's improvement mentioned above is more to do with simply changing cell supplier or their cell supplier becoming more efficient? It could just be that BMW batteries to date have been less efficient than rivals and this increase merely is them coming up to speed?

BMW moving to cylindrical cells in 2025.........I wonder which company have been using cylindrical cells in EVs since 2012 .

Yes it's not "BMW" making significant strides as such, they don't do any sort of battery R&D as far as I know! They are switching to a more modern product from their supplier.

Facts don't get people to click on "news" though. Sadly.
