When the electric forklift is operating, the concentration of the battery fluid inside the battery should be consistent with that of other batteries.

Due to the development and progress of science and technology, machines have gradually replaced traditional labor, especially in handling operations. When handling, often choose to use electric pallet stacker, which greatly reduces the human effort. However, the electric lithium pallet truck also needs the battery life of electric power when it is working. In addition, the workload of the electric pallet truck is sometimes very large, and the battery is constantly being charged and discharged, so it is necessary to maintain and maintain the battery of the electric lithium pallet truck before and after daily use. . Let's take a look!

Maintenance and precautions for lead-acid batteries:

1. When the battery is charged and discharged , the change of the battery liquid level:

1. When the battery is discharged: the battery liquid penetrates into the pores of the battery plate, so the battery liquid level will drop.

2. When the battery is charging: the battery fluid is discharged from the pores of the battery plate, so the battery fluid level will rise.

Second, about the loss of battery fluid:

1. When the battery is charging, especially near the gasification stage (Cassing Condition), the electrical reaction is that the water in the battery fluid is electrolyzed . The gas of hydrogen (H) and oxygen (O) overflows, thereby reducing the capacity of the battery fluid and increasing the concentration.

2. The above reaction will also occur when the battery is discharged, but it is not as strong as when it is charged, but when the battery is continuously discharged with a large current, the above reaction is also quite strong.

3. In the intense electrochemical reaction, if the liquid level of the battery is too high, the discharged gas will splash and overflow with the battery liquid, so that the liquid level of the battery will drop (wherein the Sulfuric acid H2SO4 is lost with the overflow of battery fluid). If supplementary pure water is used to maintain the liquid level, the liquid level of the battery liquid will change (that is, the specific gravity of the battery liquid will be insufficient). Since the splashing and overflow of the battery fluid in each unit is different, the specific gravity of each unit battery is inconsistent after replenishing water in this way, resulting in a potential difference between each unit battery, thereby affecting the performance of the battery. So try to avoid this situation when using the battery.

3. Why should pure water be added:

1. It is required that the battery fluid must be immersed in the electrode plate at any time regardless of the change of the battery fluid level (the electrode plate should not be exposed to the battery fluid). ), so as to give full play to its design requirements (capacity). The battery capacity is related to the area of u200bu200bthe battery fluid in contact with the battery plates.

2. The battery should maintain the proper concentration of the battery fluid and the consistency of the concentration between the individual cells during operation. Otherwise, there is a potential difference between each unit cell, which will cause a circulating current and affect the efficiency of the battery pack. The battery voltage is related to the concentration of the battery fluid.

3. Correctly replenishing water has an important impact on the performance and service life of the battery and can reduce and reduce sulfation.

4. How to replenish water:

1. It must be done within 1-2 hours after the battery is fully charged.

2. After the battery is used, measure the liquid level (based on the splash plate), and it should still be detected (confirm that the battery plate is not exposed during the last charge-discharge cycle).

3. The liquid level after replenishment should be 5-10 mm higher than the splash plate, but not too high (the splash plate is the benchmark).

4. After several charge and discharge cycles, when the battery fluid is charged to the point that it cannot be recharged, measure the specific gravity of the battery fluid. If the specific gravity is too low or the specific gravity of each unit cell is inconsistent, sulfuric acid should be added. Readjust the specific gravity to be between (1.27-1.29) G/CM3 (to make the specific gravity of each unit battery liquid close to the same). After adjustment, charge the battery to make the battery fluid even. This should be done by professionals.

V. Precautions:

1. During normal use, the water loss of a unit battery is about 4ml/100Ah in one charge and discharge cycle. Example: A 500Ah unit cell should be supplemented with about 20 ml of pure water.

2. After replenishing the water, the liquid level of the battery fluid must not exceed 10mm of the splash plate. The intermittently welded aluminum bars will form ionic contamination of the battery fluid, which will increase the discharge of the battery pack and damage the battery capacity and life.

B. When the liquid level is too high, the battery fluid will splash and overflow during the electrochemical reaction, resulting in a decrease in the concentration of the battery fluid, thereby reducing the battery capacity and battery voltage. And the splashed battery fluid will cause corrosion to the car body and battery.

3. If the battery liquid level is insufficient, when the battery is in use, the upper part of the battery plate will be exposed to the battery fluid, which will reduce the area of u200bu200bthe battery plate participating in the electrochemical reaction and reduce the battery capacity.

The above is about the maintenance and maintenance methods and precautions of the lead-acid battery of the electric lithium pallet truck. I hope you can gain something from it after reading it! The use of electric pallet stacker is still relatively large, so Its battery in the case of non-stop charging and discharging, the wear and tear will be very serious. If no maintenance is carried out, the life of the battery will be greatly shortened.
