Improvements & Fixes
- Fixed an issue where the charger could incorrectly report "Short Circuit Protection" or trigger overcurrent protection during charging.
- Fixed an issue where charging inrush current could cause the generator to surge or output undervoltage, resulting in the charger entering protection mode.
- Fixed a hardware protection issue where SRMOS failure in the power stage could short the battery and potentially cause component damage.
- Added support for Battery Pack Serial Number (PACK SN) configuration.
- Fixed an issue where the charger could not be activated.
Upgrade Notes
- Power the charger using the generator power cable during the firmware upgrade.
- Before starting the upgrade, verify that all power modules are powered on:
- * 9 kW charger: Both power modules must be powered.
- * 12 kW charger: All three power modules must be powered.
- Do not insert a battery into the charger during the firmware upgrade.
- After the firmware upgrade is complete, restart (power cycle) the charger before use.
