“Interview with herbert Diess of VW.
The world is changing: it is transforming into an electric automotive world where you will have less differentiation when it comes to engines. You still will have differentiation, performance-wise. You will have a rear-wheel drive, front-wheel drive, and all-wheel drive. You will have different sizes of batteries, but when it comes to the converters for the electric units or such, you get much more similarity than we have today in the industry. This is why we think hardware differentiation will probably be decreased in the future. It’s what we also see from the competition: we all share a similar battery. Now, this is a floor bottom battery that can fit in a huge range of cars; this is common. You have rear-wheel and front-wheel electric drives that are very similar in their design. We have a certain differentiation currently between 800-volt and 400-volt technology. We have Porsche and Audi are running on 800-volt. Volkswagen and the volume brand are on the 400-volt batteries, but we see a conversion even there.
That is why we decided that in an entirely electric future, one platform will do it.”

Volkswagen announces $20 billion effort to build its own EV batteries –VW says it will eventually have a production capacity of 240 Gwh.

The Energy Information Administration (EIA) made an early release of the 2021 EIA-860 data reporting that battery energy storage capacity grew more than 300% year over year, increasing from 1.4 GW in 2020 to 4.6 GW in 2021.
The boost was largely driven by the 106 utility-scale battery projects that reached commercial operations, with 3.2 GW of capacity. Consistent with historic trends, about 78% of all storage capacity added last year was built in regional transmission organization (RTO) service territories.
