Does Parking Ventilation Damage the Battery?
2 Answers
Parking ventilation does not damage the battery, but it increases engine pressure and fuel consumption. Relevant details are as follows: 1. Definition of parking ventilation: It refers to blowing natural outside air into the car without starting the compressor. When the car has been exposed to the sun all day in summer and the temperature inside is high, you can use your phone to activate parking ventilation in advance to lower the interior temperature. 2. Taking BMW as an example: BMW's parking ventilation system is an auxiliary function designed to prevent excessively high interior temperatures when the driver enters the car in summer. When this function is used, the vehicle monitors the interior temperature. When the temperature reaches a warning level, the air conditioning system will ventilate the interior to reduce the temperature.
As someone who frequently drives long distances, I have to say that parking ventilation can indeed harm the battery. The battery relies on stored power to start the engine. If the ventilation system is left on for too long after parking without the engine charging it, the battery can be drained. One summer, I forgot to turn it off, and the battery died—I had to call for a jump start. I recommend not using it for more than 30 minutes. It's best to turn on the ventilation while the engine is running or install a battery monitor. Regularly checking the battery's health can prevent issues. Replacing a new battery isn't cheap, so don't take the risk.
