This is for the Opel/Vauxhall/Chevy Volt. It is designed to take the smaller of the three modules.
Might be useful for an alternative pack too.
Of interest to anyone?

No idea. It was done by a local engineering shop.

They were made on hydraulic press. I have those made into my box too. They are suppose to strengthen the wall a bit so it doesnt wobble. No Omega profile welding required.

The house HVAC guys do it as a regular course, but it's a much thinner gauge that they work with. Which is why I asked.

Hi
What ist the thickness of the stainless steel and would you, if you built a new box go with thicker or thinner sheets?
I am trying to fit all 200kg of my I3 Battery in a single box and was wondering what sheet thickness to get.
My design sadly has no space for X-creases but I have two 20mm thick horizontal aluminium plates in the box for stability (and battery module mounting/cooling).
Would love to hear some opinions or experiences about sheet thickness and stainless/non-stainless steel.
And a safety question: I have read a few times about isolating the battery boxes. Is hat an actual thing that should/has to be done? The I3 had the aluminium modules directly bolted to the aluminium battery box, which is (as far as I know) directly bolted to the metal frame, so no isolation here.
My common sense says that 360V potentially shorted to the chassis is no good idea but I also see that in a crash that reaches the battery there probably also is a short to chassis created anyways.
I know the classifieds section is probably not the right place to post this and hope to not bring anyones wrath over me by doing so.
