Was bedeutet 37 ?

An error occurred during the RI (Internal Resistance) charging process. This specialized charging method monitors battery internal resistance, and a fault indicates a significant deviation from expected behavior or a measurement issue with this diagnostic cycle.

Häufige Ursachen

  • A significant and unexpected change or instability in the battery's internal resistance during the RI charge measurement.
  • Malfunction in the charger's dedicated RI measurement circuit or its associated sensors.
  • The battery condition is not suitable for RI charging, or the battery itself is severely degraded.

Reparaturschritte & Checkliste

  2. 2

    Consult the charger's specific manual for troubleshooting steps related to RI charging diagnostics.

  3. 3

    Verify the charger's RI charging parameters and settings to ensure they are appropriate for the connected battery type.
