Over-current of Charge Current (ECM)

Was bedeutet 3 ?

An over-current condition has occurred in the charge current path to the Capacitor Modules of the ECM. This suggests an issue with the charging circuit or a fault in the capacitor modules themselves.

• Excessive current flowing into the battery or DC bus during charging.
• Battery internal resistance is too high, limiting charge acceptance.
• Faulty charging circuit or power supply unit.
• Incorrect battery charging parameters configured (e.g., P5-xx).
• External voltage source exceeding battery's maximum charge voltage.
