Burnout#3

CravenSpeed's Electric MINI Cooper is finally starting to lay down some nice power thanks to our new LiFePO4 battery pack. Since the Dyno trials are not scheduled until next week, the best way we can display the torque right now is by smoking the tires.

Vacuum Pump

Today Chester is working on giving us power assist brakes. He made a temporary mount for the vacuum pump so that he can test it.

Before the MINI is finished the look of the engine bay will change in some significant ways. With all the electrical components in there we need to protect them from excess water. So, there will be a housing around them and the mount for the pump will be incorporated into that.

Test Run #2

One of the best things about building the EV is that we have to test it. The more we drive it, the better we'll be able to tune it to perform. So far I think things are looking pretty good. Here is a sample of a test run conducted on a closed course, of course.


Any comments?

Old Cars Can Learn New Tricks

With the new batteries temporarily in the back of the MINI we are able to take some test drives to work on fine tuning the controller. We quickly found out that The Torque is with us.

Temporary Battery Pack

During the road testing phase of the project we are using the set of 44 Lithium Iron Phosphate batteries that will eventually go where the gas tank used to be, only they are sitting in the back seat of the MINI. This way they have access to each cell while we are testing.
We have a styrafoam sheet for the big pack there too. It acts a a little safety insulation, there is plenty of energy stored in the batteries, so just like gasoline you need to treat them with care. We are hoping to get a test run in tonight before taking a break for the weekend....
