How the 800V conversion from 400V would speed up charging?

[RoadExplorer1]

Hello!
Has anyone else questioned the 400V to 800V conversion in electric motors after reading Mopar's article?

I don't think there is anything great about the efficiency loss and the added energy cost.
I don't understand how the 800V conversion from 400V would speed up charging.
To me, it sounds more like a way to reduce wire size and vehicle weight rather than improving eMPG or ownership costs.
Also, I was hoping for some clarity on the REV and charger plans, especially since 4Q24 is over and the REV was supposed to launch in 2024.
Any thoughts, guys?

Here is the article.

Yes I read it! That Mopar article definitely got me thinking too! The whole 400V to 800V conversion thing seems a bit… convoluted. I get the smaller wire gauge advantage, which is good for weight and packaging, but the efficiency losses in the conversion process do raise an eyebrow. It's hard to believe it doesn't impact overall energy consumption, even if it's a small amount. As for charging speed, going from 400V to 800V doesn't inherently make charging faster, it's more about enabling the use of higher-power chargers. Think of it like a wider pipe allowing more water to flow through at once. The real benefit is future-proofing for faster charging tech. And I'm with you on the REV, the silence is deafening! Q4 2024 is gone, and we're still waiting for any concrete news. Hopefully, they'll spill the beans soon about the launch and charger network plans.
