There are 2 ways to update firmware for EV charger
1. Update by SD card
2. Update on parameter setting page
6.1 Update by SD card
1. Prepare a microSD card with capacity not greater than 4G. Format the SD card using
FAT32.
The firmware file must be named as “App.bin”.
2. In the root directory of the SD card, rename the firmware file as “App.bin”. And create a
txt file with name of “UploadConfig.txt”.
3. Open the txt file, write “state=1” in it and save the file.
4. Insert the SD card into the charger, turn off and back on the charger, the update will start
automatically. The indicator will first flash red and then flash green with a long beep as the
end of the update(sometimes the beep sound may not be clearly heard). After the update is
done, turn off the charger and remove the SD card.
