When we sit in the car, we only need to gently turn the key, and the engine will start, which is inseparable from the participation of the battery. The battery (also known as battery) is a kind of battery. Its working principle is to convert chemical energy into electrical energy. The starting battery used in our truck is rechargeable. Let's take it as an example to briefly talk about the use and maintenance of batteries.

Main functions of battery

1. Discharge

When the vehicle starts, stops and the engine speed is low, the power required by the on-board electrical equipment is provided. At this time, the battery is in the discharge state.

2. Charging

When the engine runs at high speed, some of the power generated by the generator is stored in the battery for future use. At this time, the battery is in charge.

How to use the battery correctly

1. It is important for the battery to master the vehicle start time correctly

The instructions of each vehicle specify that the starting time should not exceed 3-5 seconds and the interval time should not be less than 10 seconds. Many people may think that it is just afraid of damaging the starter. In fact, it is wrong. Continuous starting will also cause great damage to the battery.

2. Turn off unnecessary electrical equipment when leaving the vehicle

In daily use of the vehicle, after the vehicle is stopped, turn off the unnecessary electrical equipment, which can reduce the consumption of electricity and increase the service life of the battery.

3. Do not use electrical equipment with excessive power

The power of all electrical equipment on the vehicle has been measured. When installing the electrical equipment, you must make sure whether the power of the battery can bear, otherwise it is likely to cause circuit failure.

Daily maintenance of battery

Lead-acid batteries are mainly used in automobiles, which are divided into ordinary batteries (requiring frequent maintenance) and maintenance-free batteries. Maintenance-free batteries can only be used to clean their two electrodes and maintain sufficient power. Let's talk about the maintenance of ordinary batteries.

1. Let's popularize the principle of battery first. Where is the added electrolyte?

As mentioned above, the working principle of battery is the conversion of chemical energy and electrical energy. During discharge, chemical energy is converted into electrical energy for vehicle use. During charging, electrical energy generated by generator is converted into chemical energy for storage for future use. In the process of charging, some of the water oxidized on the electrode will become gas and escape, which is why we should check the electrolyte height frequently.

2. Add electrolyte according to scale

The upper limit position and lower limit position of the electrolyte are marked on the shell of each ordinary battery. When adding, we should add according to the marked scale. When adding, it is better to keep the electrolyte of each partition at the middle of the scale.

3. Always keep the two electrodes clean

When the battery is used for a long time, it will find that many white powder will accumulate on its two electrodes. This is caused by the corrosion of the electrolyte. It can be washed away with boiling water. It is better to apply a thin layer of butter on the battery clip and electrode, and the clip must be reliable when installed. Otherwise, it is easy to burn the electrode.

4. The power should be replenished immediately

When using the vehicle, if the battery is found to be low, the vehicle battery should be charged in time. There are two ways: 1. If it can be started, let the on-board generator charge the battery. 2. When the battery cannot be started, use the external charging device to charge the battery.

5. It's a cliche, or anti-theft

The battery is one of the most favorite and most easily stolen items for thieves, so be careful to prevent theft.

As long as you are careful in your daily use, you will not cause major problems. I hope you can start from a young age and treat your car well.
