Analysis the importance of polymer lithium battery protection board

Source: 2020 - 04 - 12 20:54 hits: polymer lithium battery protection board, the importance of mobile power supply is based on the high quality of life of the stability of the battery protection board, and most of the mobile power use of polymer battery, in fact, polymer lithium battery in any application you need to add protection board, its quality depends mainly on two aspects of battery and protection plate. Mobile power suppliers suggestion: in order to the life of your mobile power supply, various kinds of electrical appliances product should be kept in dry environment lithium battery is the same, and the humidity of the air environment is relatively small. And high humidity environment conducive to the preservation of various electrical, which is determined by the characteristics of lithium battery. Lithium battery protection board, you can think of is to protect lithium batteries, lithium battery protection board's role is to prevent the battery maintenance will not be over discharge, over current protection, a charger, do not flow, output short circuit protection. Because the working voltage of the lithium battery range between 2 v to 4 v, if the battery to charge more than the range, will be charging too much. In order to prevent the battery overcharge or overdischarge, we need to use a technically to protect battery protection board, to prevent the battery failure. When polymer battery discharge protection board there will be one of the biggest limit current and set value of different equipment will also be different. When charging, if the discharge exceeds the current, protection board will be closed automatically. When the voltage to the battery voltage, display screen is full after don't continue to charge. Protection board will automatically shut down, formed as the overcharge protection. Under short circuit protection, if the battery short-circuit, when the positive and negative at the same time it is a also nothing, protective plate will be automatically closed in milliseconds, is not in the power supply, so as to form a short circuit protection, to prevent the explosion accidents. In addition, due to the lithium battery in practice accidentally short-circuits and extrusion, the dangerous situation if there is no protection board accident is inevitable.
