Temperature Overrun - Excessive Temperature

What does 302 mean?

The monitored temperature has exceeded the safe operational limit. This is a critical safety fault indicating excessive heat in the monitored area, which can lead to component damage, reduced lifespan, or hazardous operating conditions.

• High ambient temperature in the operating environment, increasing the overall thermal load.
• Internal overheating of the battery or charger components due to excessive current or load.
• Insufficient cooling or blocked ventilation for the charger or battery enclosure.

Click steps to track your progress.

1. 1

   Identify the specific source of the excessive temperature (e.g., battery, power module, transformer) using an infrared thermometer.

2. 2

   Ensure adequate ventilation and cooling airflow for the affected component and the entire charger enclosure, clearing any obstructions.

3. 3

   Reduce the charging current or temporarily pause operation to allow the component or battery to cool down to a safe temperature.
