As a means of transportation, automobiles have entered thousands of households and become an indispensable means of transportation in people's lives. With the continuous development of science and technology and the upgrading of people's modern life, various modern high-tech facilities in automobiles are constantly being added, resulting in automobiles. Auxiliary electricity is constantly being strengthened. As the main auxiliary power source of the car, the battery is one of the indispensable parts of the car, and its task is also increasing. If we use and maintain routinely, the service life of the battery will be greatly prolonged, which will lead to premature retirement, increase the cost of the owner and cause environmental pollution. Then how to carry out the daily maintenance of the car battery, what kind of driving habits should be developed to improve the service life of the battery? Here are a few points summarized:
How to make the battery of the car last longer?
First, we must pay attention to understanding the function of the battery
Some drivers do not pay much attention to the function of the battery. They think that the battery is nothing more than just starting the engine. It is even considered that the engine can be completely used after starting the engine. Therefore, the maintenance and maintenance of the battery is not paid much attention. Because of this, the car is in operation. Some of the electronic components are not damaged. What are the functions of the battery? Its main performance is in the following aspects:
1. When the engine is starting, the battery is supplied with power from the starter and the ignition system (gasoline engine).
2. When the engine is running at low speed, the battery is supplied with power to all the electric equipment and the generator excitation winding.
3. When the engine is running at high speed, the battery converts the remaining electrical energy of the generator into chemical energy for storage.
4. When the generator is overloaded, the battery assists the generator to supply power to the electrical equipment.
5. The battery is also equivalent to a large capacitor, which can absorb the instantaneous high voltage appearing in the circuit, protect the electronic components, and play a very important role in maintaining the voltage stability of the automotive electrical system. This function can only be guaranteed if the battery is in good working condition, which is easily overlooked.
If we understand and pay attention to these functions, it will not only improve the service life of the battery, but also make you feel more comfortable when using the car.
Second, pay attention to the daily maintenance of the battery
The length of service life of a car battery depends on the structure and quality of the battery on the one hand and the daily maintenance on the other hand, so we should do the following in use:
1, pay attention to the installation and maintenance
First of all, the installation of the battery in the car should be firm and reliable, to prevent the vibration of the car during driving, causing damage to the internal plate of the battery and loose connection of the external wires. Secondly, automotive start-up batteries can withstand large currents for short periods of time, but long-term discharges with small currents can lead to reduced battery life; therefore, dust, muddy water, and oxides and liquids on the terminals and ends should be removed frequently. The electrolyte overflowing at the mouth is kept clean and dry to prevent the battery from discharging itself.
2, pay attention to timely charging
When the voltage of the battery is insufficient and the light is dim and the starting is weak, the external charging should be carried out in time. The storage capacity of the battery can be reflected on the instrument panel. When the ammeter pointer indicates that the stored electricity is less than one-third of the discharge, it must be charged in time. More than two-thirds of the discharge is over-discharged. The current is relatively large when overdischarged, which is not conducive to the reduction of the active material. Sometimes the power is not enough on the road, the engine can not be started, and as a temporary measure, you can ask for help from other vehicles. If the car is driving in a cold area, avoid completely discharging the battery to prevent the electrolyte from freezing.
3, regular inspection
a. Check the battery case for cracks and electrolyte leakage.
b. Always check whether the battery cable is secure. All the joints must be in good contact to prevent sparks and cause the battery to explode. For example, always check whether the fixing bolts of the battery on the bracket are tightened. Always check whether the pole and the terminal are connected reliably. Do not place the metal on the battery to prevent short circuit; the sealing glue should be repaired in time. Check the parts of the circuit for signs of aging or short circuit.
c. Regularly check the battery electrolyte density and liquid level, check the discharge level of the battery, and prevent early decommissioning due to overdischarge.
d. Pay attention to keep the charging circuit of the battery normal. When the battery is over used, the charging indicator light may not correctly display whether the charging is normal or not. You can use the following method: keep the car in idle state at night, turn on the headlights, and illuminate Go to a fixed position, look at the center of the light carefully, then refuel, see if the light suddenly becomes brighter, and the light indicates that the generator and charging line are normal.
e, the car temporarily parked to pay attention to summer anti-exposure, winter anti-freezing. The car park for a long time, more than half the engine speed operation should be started half an hour; then removing the battery time is preferably kept separate parking protection.
