Will the charging fan of a new energy vehicle keep running?
1 Answers
New energy vehicle charging fans will keep running. This is because charging the vehicle can easily cause the battery pack to overheat. When the internal sensors of the battery detect the temperature, they will send an alert to the BMS (Battery Management System). The BMS will then send a signal to the fan, which activates the fan control terminal, causing the fan to start spinning. Once the load exceeds a certain level, the noise from the vehicle's fan will become significantly louder. Reasons for noise during charging of new energy vehicles: The noise occurs because components converting current and voltage generate heat, triggering the cooling fan of the electronic control system. This is a normal phenomenon. If the ambient temperature is relatively low and heat dissipation is good, the fan may not start or operate at a low speed. However, if the temperature exceeds 40 degrees, the fan will start running. If the temperature surpasses 50 degrees, the fan will run at full speed, producing noticeable noise. Additionally, if the fan's quality is poor, the noise during operation will also be louder. Long-term use of new energy vehicles can lead to dust accumulation in the charging system, which may also produce louder noises. During charging, new energy vehicles generate static electricity, which attracts dust from the environment onto the charging system, impairing heat dissipation. As a result, the temperature rises immediately when the charging gun is plugged in, forcing the fan to operate at maximum speed continuously. To address this, it is advisable to clean the dust and lubricate the fan. If necessary, replacing the fan with a higher-quality one can help reduce noise.
