The water level of the shared battery needs to exceed the built-in plate when replenishing water, but it should not exceed too much

Since mechanization began to develop vigorously, labor has gradually withdrawn from the 'stage'. Generally speaking, the loading and unloading of large objects all rely on machinery and equipment. For the loading and unloading of these large objects, electric pallet stacker must be used. Electric pallet stacker make good use of electricity to carry out shipping operations, which means that its batteries will always be in a state of charge and discharge. In addition, the working frequency of electric pallet stacker is more likely to have a great impact on the life of the batteries. Impact. Then how to prolong the battery life becomes a problem, let's talk about it by the electric pallet truck manufacturer.

First, the change of the battery liquid level when the battery is charged and discharged:

1. When the battery is discharged: the battery liquid seeps into the battery inside the pores of the plate, so the battery fluid 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.

2. 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 add 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 position (based on the splash-proof plate), it should still be detectable (confirm that the battery plate was 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 20ml of pure water.

2. After replenishing water, the liquid level of the battery liquid must not exceed 10mm of the splash plate, the reasons are:

A. The liquid level is too high, and the battery liquid capacity contacts the battery 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.
