Groundbreaking started on new facility that will produce the battery enclosures for GM's electric vehicles:

Magna Building New Michigan Facility To Produce GMC Hummer EV Battery Enclosures

Production at the new plant will begin early next year.

Interesting, Sounds like Magna will manufacture the battery module housings... This will be an interesting part to see how they incorporate high voltage connections and cooling. I would imagine this part is universally designed for all Ultium products.

Since this facility will not be operational until 2022, I wonder where the battery enclosures will be produced for the Edition 1 Hummers introduced at end of this year.

Good question... With traditional OEM's when they announce operational dates typically that means full series production, so I take all dates with a grain of salt. Magna may be building these enclosures on another site for prototype and early production. Considering the size of the facility and the announcement from Magna, they will be building the enclosures for all Ultium batteries. If this was just for the Hummer EV, it would slip below the cracks. I sure do want to see one of those enclosures though, see how they do the cooling and heating.

Well, Magna didn't ask me not to share any photos, but my Hummer was in their plant yesterday. First one any of them had even seen. I let some of their employees do the driving in/out of the plant. Was really neat to get a tour of their operations there. They had some of the 20 module trays for the SUV in production too, so I got to see those.

Sounds like anyone interested will be able to watch a "virtual tour" sometime in the near future.

How are the batterts replaced on the Hummer EV ? Do they have to remove ths cab and bed in order to remove the batterys from the top. This is what the picturs look the show!

How are the batterys replaced in the Hummer EV ? Rorm the bottom of the RV looks like they are replaced from the top meaning the cab and bed would have the be removed inorder to replace or service the batterys

The battery is dropped from the bottom of the Hummer like say a gas tank. There are several Bolts that need to be undone then it is lowered using a special lift to hold the batteries massive weight as it is removed.

Ya, usually they lift the Hummer to working height, so the mechanics can work under it, disconnect waterlines and wires, unbolt the pack, with a second lift under the pack to lower it down, while the truck stays elevated,

Do you think this redesign is the result of the moisture intrusion or was this intended all along?

Hard to say, but my overall confidence in GM and Ultium is not strong at the point. GM really needs to show us something now, I put GM on a "prove it" deal.

Found this report. The Magna enclosures are suspect . 2022-2023 GMC Hummer EV recalled for battery sealing

Does GM have an Engineering change for this problem or is the rumored cylindrical battery design replace it all together. Perhaps that’s why the 2 year delay.

Magna had expressed concern with GM's design before production started. @Dark-Fx had talked about this quite a while ago.
