Aluminum Battery Frame

After the Concord trip we decided to move out to start using the big battery pack (the 11kWh, 240lb A123 pack). Nick, Erich and Will started working on the next big mechanical component: the frame to hold the batteries.

We chose to build it out of aluminum box extrude and then have it welded at central machine shop by EVT's old friend Scott.

Laying out the frame before the welding!

Shiny New Frame!


Frame + Batteries!
With the batteries mounted on the frame our next step is to get all the electrical components (controller, precharge, contactors etc) on the frame as well.
