General update

We have been working on several topics simultaneously.
Measuring the bell-housing, schematics for the car, battery, control logic.

Microscribe GX2
I worked out a deal, if I can get it to work, I may measure my bell-housing... It is a very outdated arm, and the power supply was missing and the license for the software expired, but we found parts to make it work.




Above is the point cloud we generated, and then the surfaces we created so we can create the adapter that will go between the transmission and the motor.

We opened the battery with the help of a fiend from Wisconsin.  We will split the pack into 3 physical groups.  The tall group on the right will go under the rear seat, the top groups will go against the firewall, and the lower groups will either be over the motor, or in front of the motor.
The white plates over the right pack are heaters. there are a total of 6 heaters in the pack that I have found so far.



The pre-charge and main contactor, the white ceramic in-between seems to be the pre-charge resistor.


We looked inside the motor controller, those capacitors are about 1.75"x4".  The 3 IGBT's are hidden underneath of them, and mounted directly to the large aluminum water-filled cooling housing.
We are looking at the lights that are already in the dash that we can now use for other things.   The oil pressure light is the only unused.  We will re-purpose the temperature light to match the max temp for the motor and controller.  The temp gauge will also be re-scaled for the motor and controller, both of which are water cooled.  We will either need to add, or find another light to monitor the vacuum for the brakes.
The original brake switch and accelerator will be used, I had not realized it was a drive by wire car, this makes things easier.



I/O required for the DMOC adapter
Charge control is missing?
