Mmmm, toast!
I needed a way to discharge the battery pack during my BMS tests, so I headed down to my local K-mapart to pick up a space heater. It's spring here in Califoria, though so there weren't any. I figured a nice Toast-R-Oven uses lots of electricity too, and I can make toast with it later. It's pretty funny to go to the store to find something that uses the most electricity.

I am anxious for an update. Has the car hit the road? If so, how's it working out? Stats on performance? Lessons learned?
Inquiring minds want to know!!!
I am working on the battery box now, and will post updates soon. Thanks for reading!
Hi kermit
I have been watching your blog also :) . Well done on your design. It is by far the best I have seen. All the best in commercialising it.
I am curious are you using PWM and a PID control loop for the shunt control on your balancer, or just switching on and off the resistor for a fixed period (several seconds). I am thinking about using PWM and adjusting the duty cycle according to the terminal voltage.
For the communication I will probable use an isolated 2 wire I2C bus. Fibre optic comms would be nice but would be cost prohibitive.
