CES has a bit of everything. After you are done looking at the glow in the dark iPhone cases you can check out the E Rex. Mike Worry, the CEO of Nuvation Engineering gives us an overview of the car. It’s an electric sports car which has been built using a Campagna Motors T Rex as the donor vehicle. Of course the T Rex is gasoline powered so converting it to electric isn’t a feat for the faint of heart.  The E Rex was built for the Progressive Automotive X Prize which is a competition that sparks innovation. The 800 pounds of batteries and huge electric motor gets this thing from 0 to 60 in 5 seconds! They couldn’t find an off the shelf battery management system so they built their own. The custom battery management system uses a Maxim 11068 chip which is a 12 channel battery monitoring system, you can see some pictures of the controller below.

You normally see the technique that Paul used when you make a circuit board on a CNC machine. But the reason so much copper was left on the board is because the board is used as power distribution within the controller instead of bundles of wires. So what sort of juice flows through a 100 HP electric car motor controller? According to Paul it needs about 500A at 144 volts! If you are interested in purchasing one of these in kit form have a look at the Paul and Sabrina’s EV Stuff web site. […]
