That's cool to see thanks - looks so easy to work on (provided you have the battery lift equipment)... So glad it's not a "structural" battery pack with all the cells glued together... or it would be there 3-4 weeks!

It is a structural element to the vehicle. If someone gets in there while the battery is removed, the vehicle can fold up. There are warnings against this very thing.

Yes, I am aware that it contributes structural rigidity... but it's not a structural pack in modern parlance as coined by Tesla and copied by others... because the cells aren't part of core vehicle structure. In the new structural packs, the pack is the floor of the car, and the seats and seat belts, interior trim, center console, carpet etc are fastened to the pack itself and need to be stripped out of the interior before the pack can be removed.

So we are deferring to Tesla to coin terms for EVs? Anything that contributes to the structural integrity of the vehicle is part of the structure. By definition, it is a structural pack, whether the cells are glued together or not.

Hey, I'm not a Tesla fan, but when you go someplace first you get to name it...
Edit: here's some backup: Structural Batteries: The Cars of the Future Are Glued

PS: What it means is the battery cells themselves are structural, which is only possible when they are glued together into a single unit. VW uses the rigid case to stiffen the existing vehicle structure, but the cells are definitely not structural.

Also, to be clear, I'm in favor of the way VW is doing it because our cars are repairable, not disposable. But the structural pack method is lighter than what we have because they don't need as much structural support, which means they strip weight out of the pack, and they don't need a floor to the car, which also saves weight.

So to be a "structural pack" you have to have the cells glued together?

That seems to be the way automotive engineers are defining it… the battery cells themselves (not just the case) are part of the structure of the vehicle. Apparently you can’t do that without gluing them together. But that also was not the point of my comment

Cool. Im starting to think there is something wrong with my new gtx.

Picked it up 20 feb this year. At 100% from my dealer i got 167km range down to 12% when turtlemode kicks in and the car get so slow it's unbearable. Where i live there is ice and snow right now and around -10 celsius. Running on studded wintertires.

What winter range do you get?

I'd take it in and have it tested... that seems really low! My 2021 (still on original software that burns a lot of power heating the battery in the cold) can predict a total estimated range of around 340-350km (converting from miles) in weather around -10 c.

Of course, if you've been driving it on the ice rally, that could explain it I've seen what you Swedes get up to in the cold weather with your EVs:

Thank you for sharing! Very interesting to see how they constructed it. It's like a big tray held on by bolts (you can see them when you look at the undercarriage of your car). Also looks like a HUGE gasket running along the perimeter (all that blue stuff) and maybe gaskets or o-rings for each of the bolts.

Look at how much heavy equipment you need to service this thing! Well outside the capabilities of most home mechanics. That said, I'm sure there's some nut who will try and drop that battery tray onto a set of 4 Harbor Freight jack stands in his driveway.
