I recently got a electric go kart built to race at our local autocross events. First time out it smoked the previous track record set by karts and cars. I ordered a prebuilt kit for the motor and controller, it consists of a Motenergy ME1115, a Sevcon GEN4 Size 6, and a Sevcon ClearView. It runs on a 24s 5p Lipo pack made of 20 Turnagy Nano-Tech 6s 5000mah 60c Rc LiPos. It preforms very well but does not feel like it is accelerating as hard as it should be able to. After talking to multiple people about the power issue I didn't get anywhere. After talking to John at Motenergy (VERY helpful guy) he suggested that I put the kart against a wall and floor it, check the amperage/voltage. Sure enough it is only putting out 300 amps instead of the 420 that the motor is rated to. With this information I bit the bullet and ordered the Sevcon PC programmer.
This is where I have hit a road block. After getting the licensing worked out to get the Program working, the CAN-USB adapter will not link with the controller (or so it seems). I can not get it to read any data from the controller. I have tried all the different communication speeds and I have tried starting/plugging things in different orders. I have also tried reinstalling the whole program to make sure that it has all that it needs. The USB light lights up solid green every time. The CAN light stays off, sometimes it flashes red and on rare occasions of trying things it will go solid red. The program is not able to retrieve any data from the controller, or send it anything.
So at this point I'm stumped. I'm studying to become a mechanical engineer, so the complex programming errors it spits out at me mean ABSOLUTELY nothing to me. Any help would be DEEPLY appreciated at this point. The only thing I know to check is the wiring of the kit vs the wiring of the converter extension, but that all should be standardized.
So if you have any ideas, list of instructions or a cure to this problem that would be great. Probably knock another second or two off my run times.
