As a necessity in our daily life, the car has brought great convenience to our daily travel. However, many car owners often leave their cars at home without driving in order to save fuel. And the car as a consumable, if often put open, will cause great damage to the car, especially the damage to the car battery is very large. Car battery, as a very important accessory on the car, is charged by the engine. So how long does it take for the car to run before the battery can be fully charged? Today Xiaobian will tell you about some knowledge about batteries.
Automotive batteries are not only a particularly important component of the car, but also a component that is easily lost on the car. Car batteries can not only provide electricity for cars, but also store electricity. When the car engine is just in place, the battery provides the required electrical energy to the starter, ignition system and in-car electrical equipment. When the car engine is operating normally, the generator will charge the battery.
So how long does it take for the car to fully charge the battery? The general starting time of the car is about three seconds, which consumes about 0.3 milliamps of electricity. The electricity used when all the electrical equipment on the car is turned on is also about 0.3 mA. So when we turn off all the electrical equipment in the car, the car with a displacement of less than two liters can run for about 5 to 10 minutes to fully charge the battery.
But many car owners often park their cars at home, and when the car is parked for too long, the electricity in the car battery will slowly disappear. When the car is in a state of power deficit, if the car engine is used to charge the battery, it needs to be charged for about 20 hours to fully charge the battery. Therefore, everyone must drive a car from time to time, and do not often park the car in the underground parking lot. If there is really no time to open, unplug the negative electrode of the car battery to avoid battery loss.
The life of the general car battery is about three to four years, when the car is more difficult to start than usual or the battery appears bulging, indicating that the battery is about to be scrapped, we need to replace the new battery. When the battery fault light is on, it means that there is a problem with the car battery, and we need to send the car to the repair shop to check it. So how do we usually maintain the battery to extend the service life of the battery?
The first is that xiaobian just mentioned that you should drive a car often and don't park at home for a long time. Even if you don't have time to drive a car, you must start the car engine regularly and charge the battery.
Secondly, everyone must turn off the headlights and air conditioning before stopping the car, and many car owners often forget to turn off the headlights and air conditioners before stopping. Although the air conditioner cannot be activated after the car is turned off, the blower is still rotating, which will still consume the energy of the battery. And some old models do not have the function of power outage after the shutdown, so everyone must turn off the headlights and air conditioning before stopping the shutdown.
Car battery as the core component of the car plays a very important role, we must usually take good care of the car battery.
