ECU Software Updates & BMS Recalibration

OTA update troubleshooting, BMS SoH calculation algorithm recalibration, and CAN gateway diagnostics.

Software & BMS Optimization

Modern EVs rely on dozens of ECUs synchronized via high-speed CAN and FlexRay buses. BMS recalibration aligns battery capacity estimation with actual cell chemistry health.

Key Diagnostic Areas:

  • OTA Update Lockout Recovery: Clearing firmware flashing errors that prevent vehicle charging.
  • SOC / SoH Memory Reset: Resetting BMS RAM after cell rebalancing to re-establish true driving range metrics.
  • Gateway Diagnostics: Checking CAN bus noise isolation against high-frequency inverter switching interference.
