What are the uses of lithium battery protection board

With the development of the economy, electronic products have entered the homes of ordinary people. People’s demand for the use of electronic products is also getting higher and higher. With the higher and higher demand for the use of electronic products, people’s demand for lithium batteries is also getting higher and higher. As a battery with relatively large electric storage, lithium batteries are used Used in various electronic products. However, some unscrupulous merchants in the market have aimed at this point. They flooded the entire market with a large number of fake and inferior batteries, making it difficult for consumers to buy genuine products. These counterfeit and shoddy lithium batteries have serious quality problems. These counterfeit and shoddy lithium batteries are likely to have overcharge and overdischarge problems, which may cause an explosion, or a short circuit of the internal circuit may cause an explosion. However, there is a product that can effectively guard against lithium battery overcharge, overdischarge and short circuit of the internal circuit, it is the lithium battery protection board. Today, I will explain the use of lithium battery protection board from a professional perspective. We all know that the lithium battery we use is actually composed of several small internal lithium batteries connected in parallel. There are several plastic-like plates separating them in the gaps between the internal lithium batteries. These small plastic boards are actually lithium battery protection boards. In fact, the lithium battery protection board is not made of plastic. It is composed of several non-conductive fiberboards wrapped with a layer of oil. We all know that oil is not conductive. This is the reason why the lithium battery protection board can isolate several lithium batteries and prevent short circuits in the circuit. Secondly, we talked about the lithium battery protection board also has the function of protecting the battery and guarding against battery overcharge. When the external power supply continues to charge the battery quickly, the lithium battery protection board will be used for protection. When the internal power of the lithium battery reaches the saturation level, the internal circuit of the lithium battery protection board will automatically cut off the external fast charging power supply. So that the external power source cannot enter the battery. This is exactly the principle that the lithium battery protection board protects the battery from overcharging. We also went to the lithium battery protection board to protect the lithium battery and guard against the over-discharge function of the lithium battery. When the lithium battery is over-discharged, the internal memory content of the lithium battery will undergo a qualitative change. At this time, the lithium battery protection board can sense this and quickly cut off the discharge power so that the lithium battery will not discharge all the electricity. So as to ensure the stability of the internal current of the lithium battery, and guard against the over-discharge of the lithium battery.
