2. Preparation for Visit
- Check if a component is faulty or if the firmware is to be updated. Refer to chapter 4 and chapter 5 and determine the fault location based on fault information reported by the user.
- Prepare a USB key for firmware upgrade or log exporting.
- Obtain the SOC information of user’s system and prepare a module with similar SOC or BMS Box for onsite replacement.
- Prepare a set of network cables and power wires.
- Prepare uninstallation and installation tools, such as hex key and wrench.
3. Onsite Process
Follow the steps below to locate the fault and take photos for every step:
- (Optional) if only the firmware needs to be updated, implement the upgrade through the USB port of the BMS Box. For how to upgrade firmware through the USB port, refer to Firmware Upgrade Via USB.
- Export log through the USB port. For how to export logs, refer to Log Exporting.
- Check PCS. (if the PCS reports any fault and if it works properly)
- Check the ESS system. ( if any damage on appearance)
- Check cables and wires. (Whether they are inserted properly or not and whether they are damaged or not)
- Reset the breaker to check if the fault still exists.
- Check the LED status and take actions referring to the LED display in chapter 4.
- Confirm the error code displayed on the screen of the PCS is consist with that the user reports. Refer to the error code in chapter 5.
- Confirm the faulty component.
- Replace the faulty one. For how to replace a BMS Box or Module, refer to the Battery Replacement Guide.
