What Are the Reasons for Poor Air Conditioning Cooling in New Energy Vehicles?
2 Answers
New energy vehicle air conditioning may not cool properly due to insufficient or too little refrigerant, or minor refrigerant leakage. Excessive refrigerant can also cause the air conditioning to not cool; because there is a required proportion of refrigerant volume in the air conditioning system. Solutions for insufficient or too little refrigerant: 1. It can be observed from the sight glass on the top of the dryer. During normal operation of the air conditioning, if there are continuous, slow bubbles in the sight glass, it indicates insufficient refrigerant. 2. If obvious bubble flipping occurs, it indicates severe refrigerant shortage. 3. If the refrigerant is insufficient or too little, the solution is to add refrigerant. However, it should be noted that if adding from the low-pressure side, the refrigerant bottle must not be inverted; if adding from the high-pressure side, the engine must not be started.
There are quite a few reasons for poor air conditioning cooling in new energy vehicles. I've personally encountered this issue while driving an electric car. First, it could be due to insufficient refrigerant or leaks, which prevents the system from properly circulating cold air. The compressor is a critical component - electric vehicles use electric compressors, and if the battery power supply is unstable or the compressor fails, cooling performance will naturally suffer. The cooling fan might be stuck or have too much dust buildup, affecting heat exchange. Clogged air conditioning filters are a common problem, especially in dusty urban environments where lack of timely cleaning can block airflow. Software malfunctions are also not uncommon - delayed system updates may cause control disorders. Additionally, when the battery condition is poor, the air conditioning will prioritize power saving by automatically reducing cooling power, resulting in poor performance. I recommend first checking the filter, and if that doesn't help, take it to a professional shop to test the refrigerant and voltage.
