How to maintain 18650 lithium battery cells components?
The components of 18650 lithium battery cellss indicate that you should always wipe the battery components with a soft and clean cloth, and check them regularly. If you find that there are broken glass, scorched backplane, obvious color changes, etc., you should make timely adjustments or replace the battery components. Then Next, I will introduce the relevant content to you in detail.
1. Maintenance methods of 18650 lithium battery cells modules
1. The surface of the battery component should be kept clean. Use dry or damp soft and clean cloth to wipe the battery component. It is strictly forbidden to use corrosive solvents or hard objects to wipe the battery component. Battery components should be cleaned when the irradiance is lower than 200W/m2. It is not advisable to use liquids with a large temperature difference from the components to clean the components.
2. The battery components should be checked regularly. If the following problems are found, the battery components should be adjusted or replaced immediately. The battery components have broken glass, scorched back plates, and obvious color changes; there are bubbles in the battery components that form communication channels with the edges of the components or any circuits; the battery component junction boxes are deformed, twisted, cracked, or burned, and the terminals cannot be used properly. touch.
3. The live warning mark on the battery component must not be lost.
4. For battery components with metal frames, the frame and bracket should be well combined, the contact resistance between the two should not be greater than 40, and the frame must be firmly grounded.
5. When working under no shadow conditions, when the solar irradiance is more than 500W/m2 and the wind speed is not more than 2m/s, the temperature difference on the outer surface of the same battery module (the area directly above the battery) should be less than 20°C. . Photovoltaic power stations with an installed capacity greater than 50kWp should be equipped with infrared thermal imaging cameras to detect temperature differences on the outer surfaces of battery components.
2. Factors affecting the output characteristics of 18650 lithium battery cellss
1. Effect of temperature on the output characteristics of 18650 lithium battery cellss and components
As we all know, when the temperature of 18650 lithium battery cellss and components is high, the working efficiency decreases. As the temperature of the 18650 lithium battery cells increases, the open circuit voltage decreases. In the range of 20-100 degrees Celsius, the voltage of the 18650 lithium battery cells decreases by about 2mV for every 1 degree Celsius increase. The photocurrent increases slightly with the increase of temperature, about every 1 degree Celsius. The photocurrent of the battery increases by one thousandth when the temperature rises by 1 degree Celsius. In general, for every 1 degree Celsius increase in temperature, power is reduced by 0.35%. This is the basic concept of temperature coefficient. Different 18650 lithium battery cellss have different temperature coefficients, so the temperature coefficient is one of the criteria for judging the performance of 18650 lithium battery cellss.
2. Effect of light intensity on the output characteristics of 18650 lithium battery cells modules
Light intensity is proportional to the photocurrent of 18650 lithium battery cellss and components. Within the range of light intensity from 100 to 1000 watts per square meter, the photocurrent always increases linearly with the increase of light intensity; while light intensity has little effect on voltage, and changes in temperature Under fixed conditions, when the light intensity changes within the range of 400-1000 watts per square meter, the open circuit voltage of 18650 lithium battery cellss and modules remains basically unchanged. Therefore, the power of 18650 lithium battery cellss is basically proportional to the light intensity.
