Battery Overvoltage

Hva betyr 23 ?

The connected battery's voltage has exceeded the maximum safe limit during or after a charging cycle. This is a critical condition that can lead to excessive gassing, overheating, and potential irreversible damage to the battery if not promptly addressed.

• A malfunction or miscalibration in the battery charger's output voltage regulation circuit.
• An incorrect battery type or nominal voltage setting selected in the charger's configuration, leading to charging at too high a voltage.
• External factors causing voltage spikes or uncontrolled voltage rise on the battery terminals.

1. 1

   Immediately disconnect the battery from the charger to prevent further overvoltage and potential damage.

2. 2

   Verify the charger's output voltage regulation by measuring its open-circuit voltage (if safe to do so) or output voltage with a dummy load.

3. 3

   Check the charger's configuration parameters to ensure the correct battery nominal voltage and appropriate charge profile are selected for the connected battery type.
