Moved to a new location
By Ricky Gu
Sorry about having no update for almost 2 months. In December, we put the project on hold to focus on final exam. Then during the winter break, the school was closed so we could not work on the vehicle.
Unfortunately in January, due to limited space in the ICICS building, we had to find a new location to work on the car. I’ve temporarily towed the car to my parents house and we will be continue to look for a new space to work on campus. Here are some new photos update.
Looking good!

Hi there,
Nice to see your car together. I work with Roger. Watch out for vibration causing the edge of the cable conduit to cut through the motor cable insulation. And supporting the cables with structure, and adding split washers should keep them from shaking loose from their terminals.
Is your pack negative connect to the car chassis? Are you connecting the charger chassis to the traction pack negative? I think it would be better if the charger chassis is not connected to pack negative. The charger chassis is connected to safety ground of the AC input.
AFAIK, most people do not connect their traction pack negative to the car chassis.
Hi Gregory,
Thanks for your support and advice. supporting motor cable is a good idea, we will look into it further. We were unable to put on the lock washer due to the sheer thickness of our home made terminals, but we do have some wave washers available.
The pack ground is not connected to the chassis ground. We have the charger chassis grounded to the car chassis(12v aux battery ground). When you say connected to the safety ground of AC input, that’s the ground wire on the ac input?
the best thing about AC motors is that they require less maintanennance-,,
AC motors are really more efficient than DC motors, requires less maintennance too”:-
for years we have been using ac motors for industrial use and yes they last longer -
