upgrade instruction:
Update the FW by USB. Separate BA and CA files when updating FW v2.05(important). If BA and CA FW are updated together there is a possibility that there would be no automatic reboot when upgrade is done and also would cause backend to disconnect
Please follow this rule for upgrade with USB or OCPP backend:
- If only BA and CA need to be upgrade, please upgrade file 5505604248F and 5505604249F separately.
- If more than these two boards need to be upgrade, the files(Ba, Aux and Relay) except CA (5505604249F) can be bundled in a zip file “DCWB25kW.zip” and be upgraded together. After upgrading the bundled files then upgrade CA file individually.
- When updating just the CA file, save JUST the file, or Zip the file, in the root directory of flash memory
For downgrade from version v02.05:
- If downgrade is done via OCPP backend, everything can be bundled with a file “DCWB25kW.zip”. (Because charger already is v02.05)
- If downgrade is done via USB, please keep following the rule as upgrade.
[DC wallbox 25kW FW] v02.06 [This firmware contains only one file for the BA board.]
Download the upgrade instruction from here.
Note: for this version you only need to update the BA board. It is recommended to update the CA, AUX, and Relay control BD boards to the latest firmware (get those from link v2.05). Use the correct firmware based on the charger model. For example, if the charger has CHAdeMO and CCS guns, use the firmware from EU_CHA_CCS. Save the firmware file to a USB drive to update the charger locally, or use the file to update the charger remotely via OCPP.
