It’s been two weeks since I have posted an update so there is lots of progress to report.
1. The BMS version two is up and running with a single MAX6802 (I should be getting some more chips any day now). There is just one bug I need to figure out. The last battery in the chain is reading 0 volts. All the others read fine. This could be because it is supposed to be wired up to the next string which isn’t installed yet. However, I think there might be something else going on. We’ll see…
2. I welded up a new aluminum mounting bracket for all the high voltage electronics.
This tray will be the final mounting location for everything that uses full pack voltage; motor controller, charger, etc… It will be accessed from the rear hatch:
3. I remounted and started the process of re-wiring all of the high voltage electronics. I am mounting everything to a piece of polycarbonate which then bolts to the aluminum bracket I made.
4. I installed my new 500amp 50mV shunt. This should give me better readings than the previous 1200amp 50mV shunt.
5. I received and tested all the LED lighting for the car. These will replace the standard incandescent backup lights, turn signals, brake lights, and side markers.
6. I cut out the safety cover for the battery box. It is 1/4″ polycarbonate. Later I will figure out the best way to vent it.
