What should I do if the battery is dead?Teach you how to solve the feeding problem

【The owner's family car knowledge】The weather is getting colder and colder. Some car owners may have encountered a situation where the battery suddenly went out one morning and could not get into the car. Why does the vehicle run out of electricity frequently in winter? This is because the car battery is most afraid of low temperatures. In a low temperature environment, the battery capacity is much lower than that at room temperature.

Owner's question:The car is fine, how could it suddenly run out of electricity?

1. The anti-theft system runs for a long time and consumes electricity

Many car owners think that after closing the switch, the car will be in a state of power failure. In fact, many devices are still in operation. The most common is the anti-theft system installed on many car models. As soon as the car door is locked, the system starts to work, and its power consumption is much smaller than that of equipment such as headlights. But after a few weeks, when the car is not started for a long time for charging and the battery is in a poor state of storage, the battery will run out.

In addition, some vehicles equipped with an intelligent remote anti-theft system, because of the use of GPS positioning technology, can be used by vehicle owners to alarm through the remote control center in any state, and this system is that the vehicle will continue to work as long as the vehicle is connected to the battery. Therefore, its power consumption is greater, so it is more prone to run out of battery power. Therefore, it is recommended that if the vehicle owner needs to park the vehicle for a long time, start the vehicle once every two to three weeks, let the engine run for 10-20 minutes, and recharge the battery with a certain amount of power.

2. The vehicle is running despite the stalled parts

Is the car completely stationary after the flame is turned off? In the traditional impression, as long as the car key is turned to the closed state, all parts of the car are in a stopped working state. However, when the engine temperature is too high, even if the car is turned off and the car key is pulled out of the car, the cooling system will automatically start to cool the engine system. Only when the engine system temperature drops, the cooling system will automatically stop working, usually this process takes 3 to 5 minutes.

There are still many situations where a car like this is stalled and electronic equipment is still running. In some high-end cars equipped with sunroof ventilation system, the sunroof exhaust system will continue to work for 10 to 20 minutes after the flame is turned off, in order to remove the cold or hot air in the car and keep the air inside and outside the car at the same temperature. Reduce the fogging or excessive dryness of the interior parts caused by the temperature difference. Therefore, the owner found that there is still a slight whirring noise in the car after the flame is turned off. Don't be too nervous. It is actually the ventilation system that balances the air temperature and humidity inside and outside the car.

3. Forget to turn off the headlights when you lock the car and leave

With the increasing number of novice drivers, there are more and more "Ma Daha" drivers. I stopped the car without turning off the lights, and after a night, the battery was overworked and shocked, and finally went on strike. Of course, many vehicles now have their headlights turned off automatically when the car is locked, but there are still some vehicles that need to turn off their headlights manually, so be careful outside.
