7。 トラブルシューティング

If you encounter issues with your DC HOUSE LiFePO4 battery, refer to the following common troubleshooting steps:

• バッテリーの電源が入らない:
  • Ensure the one-button switch is pressed to the 'ON' position.
  • すべてのケーブル接続がしっかりと固定され、極性が正しいことを確認します。
  • Verify the battery's state of charge using the smart display or app. If critically low, attempt to charge.
• No Display/App Data:
  • For the smart display, ensure the communication cable is securely connected to both the battery's UART port and the display.
  • For the app, ensure Bluetooth is enabled on your device and the battery is paired. Restart the app and try reconnecting.
• バッテリーが充電されていません:
  • Check the charger connection and ensure the charger is functioning correctly.
  • Verify the ambient temperature is within the charging range (0~55℃). The BMS will prevent charging below 0℃.
  • Check for any error codes or warnings on the smart display or app.
• Battery Not Discharging (No Power Output):
  • バッテリーの電源がオンになっていることを確認してください。
  • Check for any over-current or short-circuit protection activation (the BMS will temporarily cut off output). Over-current protection typically auto-resets after 32 seconds.
  • Verify the ambient temperature is within the discharging range (-20~55℃). The BMS will prevent discharging below -20℃.
  • Check the battery's state of charge; it may have reached its low voltagカットオフ。
