Brief analysis of the importance of polymer lithium ion battery protection board

The importance of polymer lithium-ion battery protection board The life of mobile power is based on the stability of high-quality battery protection board, and most mobile power sources use polymer batteries. In fact, polymer lithium-ion batteries need to be used in any application. Adding a protection board, its quality depends on two aspects of the battery and the protection board. The mobile phone mobile power supplier recommends: For the service life of your mobile power, various electrical products should be placed in a dry environment where the lithium-ion battery is the same, and the air humidity is relatively low. The high humidity environment is not conducive to the preservation of various electrical appliances, which is determined by the characteristics of lithium-ion batteries. Lithium-ion battery protection board, as you can imagine, is used to protect lithium-ion batteries. The purpose of lithium-ion battery protection board is to prevent battery maintenance from over-discharge and over-current protection. There are overcharge, no flow, and output. Short-circuit protection. Because the operating voltage range of lithium-ion batteries is between 2V and 4V, if the battery continues to be charged beyond this range, it will be overcharged. In order to prevent the battery from being overcharged or over-discharged, we must technically use a protective board to protect the battery and prevent battery failure. When the polymer battery is discharged, the protection board will have a maximum current limit, and the setting value of different devices will be different. When charging, if the discharge exceeds this current, the protection board will automatically shut down. When the voltage reaches the maximum voltage of the battery, the display will not continue to charge after it is fully charged. The protection board will automatically shut down to form overcharge protection. Under short-circuit protection, if the battery is accidentally short-circuited, when it is a positive and negative electrode at the same time and there is nothing, the protection plate will automatically close within a few milliseconds and not in the power supply, thus forming short-circuit protection and preventing explosion The accident happened. In addition, since lithium-ion batteries will be accidentally short-circuited and squeezed in actual operation, this dangerous situation cannot be prevented if there is no protection board.
