Charger shows much lower charging current than expected, even though settings are at maximum and no error code is present.

Safety first: Reduced current is usually a protective behavior, not a direct hazard.

• 1. Check charger settings: Confirm that the Primecom current limit is set to the desired value (e.g., 32A or 40A) and not reduced.
• 2. Verify circuit rating: Ensure the supply breaker and wiring are sized for the desired current; some models auto-limit based on configuration.
• 3. Monitor temperature: If the charger is hot to the touch, improve ventilation and reduce ambient temperature.
• 4. Measure supply voltage: Low voltage can cause the vehicle to draw less current. Have an electrician check voltage under load.
• 5. Firmware or hardware issue: If all conditions are normal but current remains low, the current sensing or control algorithm may be faulty; professional diagnosis and possible board replacement are needed.
