The MR2 got a new touchscreen display that shows real-time information about the battery pack. The information can also be sent by Bluetooth to any Android device with the Torque application.

The battery transplant is now complete and the MR2 is back on the road, thanks to seven long hours of work on Saturday by some dedicated students. Re-wiring the Orion BMS took a lot of time and patience (and a call to their ever-helpful customer support line), but it is now working to equalize our new battery pack. There are still some final details to attend to, but now our attention can shift to the Volkswagen and preparing for the EV challenge. Check out the pictures of our progress.
Drilling out holes for the battery straps.
The front box, ready to go back in!
Moving the bug out of the way, so the MR2 can get on the lift.
Since the new cells are smaller, we need new holes for the battery cables.
The back box is almost finished...
Everything is in place up front.

This week has been rather hectic in the shop. We have run some cables and repaired the parking brake in the Volkswagen, and are modifying the motor, coupler and adapter plate to make everything fit. In the MR2 we have removed the old Thunderskycell and are modifying the battery boxes to accept the smaller, yet more energy dense cells. We will then have to do a rewire of the Battery Management System (BMS) before the car can get back on the road.
Also, we received a very generous donation this week from one of our sponsors, Atlantic Tool and Die!
