When the weather is not very hot, using the parking air conditioner while driving does have the effect of energy saving and fuel saving. As far as the parking air conditioner itself is concerned, as long as the product is verified by the vibration test of the car air conditioner, there is no problem using the parking air conditioner when driving!
However, the only problem with the current technical state of the original car is: the generator of the original car may generate a small amount of electricity. As mentioned in the previous question, the generator of the original car may use the parking air conditioner when driving. , Not to mention that the battery may be in a state of loss due to lack of charging for a long time!
At present, there are generators with increased capacity on the market, such as 110A generators. For general parking air conditioners, they should be able to use the parking air conditioner when driving or stopping. When the weather is not too hot, parking this The air conditioner uses half of the power generation, and the other half of the generator is still used to charge the battery.
After installing the parking air conditioner, the air conditioner only used 4 hours for the first time the air conditioner was used for low voltage protection. Why did the air conditioner take only 2 hours for the second time to protect the low voltage?
The above-mentioned problem is mainly caused by the second battery not being fully charged. Before the parking air conditioner is installed in the vehicle, the load of the on-board electrical appliances using the battery is not large, and the battery can be fully charged in 1 hour after the engine is started; after the parking air conditioner is installed, the air-conditioning load is much greater than other vehicle on-board electrical appliances. The power consumption is large. The battery of the air conditioner is fully charged for the first time and can be used for 4 hours. After that, it may take 4 to 5 hours to fully charge the battery.
