The car supports single-phase charging, but the actual charging power is only 3.3kW instead of 3.6kW.

In order to better understand why the charging power of the car is only 3.3kW instead of the expected 3.6kW when using single-phase charging, it's essential to look at various factors that could potentially contribute to this discrepancy. Here are a few more aspects to consider:

1.Voltage fluctuations: Even though the power supply to the charging station is supposed to be constant, it's possible that there may be occasional fluctuations in the voltage. These fluctuations can lead to a reduction in the actual charging power delivered to the car.

2.Power factor: The power factor is the ratio of real power to apparent power in an electrical system. If the power factor is less than one, it means that the charging system is not operating at its maximum efficiency. In this case, the actual charging power could be lower than the expected value due to the poor power factor.

3.Internal resistance: The internal resistance of the car's battery can also have an impact on the charging power. As the battery gets older, its internal resistance typically increases, which can result in a decrease in the actual charging power.

4.Software limitations: Some cars may have built-in software limitations that cap the charging power below the maximum level. This could be a safety feature to prevent damage to the battery or other components, or it could be due to regional regulations or market-specific requirements.

To identify the root cause of the discrepancy in the charging power, start by examining the charging equipment and infrastructure, as well as the car's battery and charging system. If no issues are found, consider consulting with the car's manufacturer or a qualified technician to further investigate the problem and identify potential solutions.
