Like all home-project software, the dash/speedo will never be finished - but it now has everything I wanted it to have - and the displays are all glued in (silicone)!
Main display
- Instantaneous current
- Battery pack voltage
- Speed
- Estimated range remaining in 10 meters steps
Left 16x2 display
- State of Charge easy indication
- AH used (for more complicated evaluation of battery pack)
Right 16x2 display
- Trip meter in 10 meter steps
- Odometer in km (I might change this to 100 meter steps)
Even when I used the flash the 16x2 displays are quite readable.
I also added some special characters so the SOC indication could have 80 steps rather than only 16. It's resolution is now 200mA/.Hr or 0.2 AH. Note that the last bar is thinner because we have 14.6AH remaining.
All I have to do now is clean up the display wiring and mount the assembly into the speedo housing. The captive nuts are already installed and the holes have been drilled in the housing. I have to make a gasket for the front cowl (that holds the perspex front on) but that should be a small task.
Next week I'm off work for some real EV progress!
