==> needs to be uploaded to the Arduino IDE Library



From the 2 zipped files EV Display.tft if the file that goes on the screen and the EVDisplay.HMI is the file that can be modified with the Nextion software.

If anybody has an idea of what else should be on the main screen please let me know. There is still some space.

Would be nice is a real programmer would work on this.

Looks awesome! I use nexion display too - but a small one.
To keep it clean, for the main screen I just display the motor direction, speed and vehicle state - (drive, charge, error) and error pop-ups. Ex. motor temp H (warm)/yellow, HH (hot)/red. Then I have separate details screen for all my hardwares - motor details, battery details, ibooster details, charger details, etc.
Just an idea.

put a screenshot with yours. the more ideas the better. I am going to implement the error popup on mine too. good idea.

I also want to add on the 2nd BMS, charging details. I will have to purchase the CCS board for that.

This is the new version and probably final for a while.
There is an invisible slider on the top Right for screen light.
The red line for instant power shows Amps used. I do not think the Regen bar on the left can be made possible in Nextion
Battery green fill goes up and down depending on the charge.
Battery percentage number turns to red under 20%.
Inverter temperature turns to red over 75C(is this threshold right?)
Motor temperature turns to red over 85C (is this threshold right?)
Charge, Regen and creep mode can be pushed on and off but there is no code behind them. Need to figure that out in the future.

Inverter temp max (default derate) is 85C
i think the motor temp (tmpm) is allowed to go quite high.
you ll have to monitor the temps during your first runs

I took the screen protector and the screen looks a little washed out. Probably need to start looking at Dwin screen.
But the software is different.

Updated the background to black to get more contrast. On the screen looks dark gray.

I updated the files. By mistake yesterday I exported the pictures from Photoshop at 70% instead of 100%
