Trexa electric vehicle development platform

domenick · Jan 20, 2010

Tired of electric vehicle designs that don't quite flip your buttons? How about you develop your own starting with a lithium-powered all-wheel-drive platform from Trexa.

I've got a little more technical info than what's in the post. Let me know if you want more specs.

How much?

Regarding the price Trexa says, "The platform price varies depending on the number of features selected. (Trexa plans to release specific pricing later this year.)"

I expect it's expensive but it comes with a developer's kit which includes CAD models and interface hardware among other things.

This looks like the 2002 GM surfboard concept the Autonomy. Here's a link to a photo gallery.

TREXA Unveils New Enertube Prototype

http://inhabitat.com/?p=237246

Electric vehicle platform maker TREXA has just unveiled a new production prototype in conjunction with its filing for a patent for the company’s unique Enertube energy storage system. TREXA’s Enertube is a tubular chassis frame that serves as both the backbone of the vehicle platform and a housing for a scalable battery pack.

There was an earlier thread about their previous platform:

Edit: moderators have merged the two threads so you can see their old rendering and their new prototype.
Quite a change from the concept to the execution.

Note, that tube doesn't seem big enough to hold a lot of battery capacity. When they say 'scalable' do they have plans to add more battery capacity in parallel tubes or something like that?

Somehow their old chassis looks more evolved/finished than the new one.

Given that the image of the "old chassis" is just a rendering, it's not surprising that it looks more finished than something they actually built.

AutoblogGreen also has some bigger pictures in the gallery accompanying their Enertube post. Also, expect to hear more from them before too long.

Some other concept renderings they did a while back:

Ah, OK. Fatter tubes if you want more range.

Those don't seem to be 18650s in there.

Eberhard · Apr 15, 2011

why not add more tubes in parallel?

Whether or not this is important, this platform makes battery switching impossible.

ernst · Apr 15, 2011

Battery switching impossible? Maybe not, empty stick out fresh stick in.

So, umm, where does the body attach to this thing? Attaching along the spine is not seem structurally sound.

Hmm:

...Vehicle applications mount to the TREXA vehicle platform by way of several hard points located on the front and rear suspension subframes. The subframes are attached to the Enertube...
