I just learned how to secure my EVSE in the wild ;-) . Unfortunately, I'm not sure my driving skills are good enough.

Both OpenEVSE enclosures (diecast alunimum and Poly) are in a strain lab. They will be tested to distruction with a fixture that simulates a tire at 10,000 and maybe 20,000 lbs. I will have a full report and photos in a couple days.

If you have a Frito-Lay truck, bring it over. I will let you run over an enclosure in exchange for a few bags of chips...

It was pretty easy driving up....but when coming down the enclosure launched 20 feet or so up the street. It survived that too with a few scratches on the bottom where it launched/slid...

Awesome, and it looks like it was kinda fun. Thanks for crash testing your products.

The cast is stronger than I would have thought, but obviously both are fully capable of holding some electronics to recharge vehicles.

Thanks a lot for testing this out. Looks like the poly case is as strong as the aluminum case and I assume poly case is lighter in weight? It sure looks like it's going to be able to easily handle getting run over by most cars in a parking lot.

That's great news Chris! And thanks for bringing them down last week for us at the meet to check out and look at. I can't wait for the bigger box to hold the higher power stuff! 8-)

Jason

P.S. Thanks for the tips on the new API code! It works great! :D
