Lithium batteries do not need a protective plate, but the battery is damaged very quickly. The protective plate is used to protect the battery from overcharge, overdischarge, short circuit and other problems. battery So important.
What is a lithium battery protection board?
The lithium battery protection board is a charge and discharge protection for lithium batteries connected in series. When fully charged, it can ensure that the voltage difference between each battery is less than the set value, thereby achieving equal charging of each battery in the battery pack, effectively improving the charging effect in charging mode serial.
Simultaneously detect the overvoltage, undervoltage, overcurrent, short circuit and overheating status of each battery cell to protect and extend battery life. life ofbattery. Undervoltage protection prevents each battery from being damaged due to over-discharge when used for discharge.
The relationship between the protection plate and the lithium battery The finished lithium battery mainly consists of two parts, the lithium battery core and the protection plate . Lithium battery cells are mainly composed of positive plates, separators, negative plates and electrolytes; positive plates, separators and negative plates are rolled or rolled, wrapped, filled with electrolyte and packaged to form a battery core.
Many people don't know the role of lithium battery protection board. Lithium battery protection board, as the name suggests, is used to protect lithium batteries. The function of the battery protection boarde lithium is to protect the battery against discharge, overcharge and current, as well as to provide protection against output short circuits.
Do lithium batteries need a protection board? Regarding this question, people who think that lithium batteries do not need a protection board think that the lithium battery will be damaged if it is connected. to the protection board or not, and the protection board will cause long-term damage. Spots from unused lithium batteries emit light.
Regarding this statement, it is obvious that the idea arose from the lack of knowledge about the function of the protection panel. Since the protection plate acts as an additional layer of protective barrier for lithium batteries, the function of the protection plate is to ensure the safety of lithium batteries andto extend their lifespan. Without a protective panel, not only is the service life difficult to guarantee, but it is also very dangerous.
Therefore, when the lithium battery can be completely immune to the effects of overcharging, overdischarging, etc., and when the design of the lithium battery itself even can completely replace the role of the protection plate, lithium battery You may not need a protection board, but at this stage, lithium batteries still need a protection board .
Of course, if the protection plate is not well designed, it will also damage the battery. Therefore, when purchasing lithium batteries, it is best to purchase lithium batteries produced by regular manufacturers through regular channels. In this case, the quality of lithium batteries is further guaranteed.
