Lithium battery of battery pack to how to install protective plate

Li-ion battery of battery pack to how to install protective plate, how are we going to install the lithium battery protection board? Protective plate installation method is what? We guangdong lithium battery manufacturer to tell you now! Is designed to ensure stability of protection plate, and ensure the lithium ion battery won't be overcharged or excessive discharge. Due to the lithium ion battery overcharge discharge can cause cell damage or explosion, fire and other dangers, so the introduction of lithium-ion battery protection board has also appeared in. With the emergence of iron phosphate lithium ion battery, it is said that the iron phosphate lithium ion battery are not afraid to put a charge, so the can use without protection plate. However, so far, there has been no battery maker publicly announced using protection circuit. Board is the purpose of bodyguards, protect board is to ensure the stability of the lithium ion battery. As a result of the lithium ion battery overcharge, discharge and short circuit may cause the battery scrap, protective plate had the protection effect. If can ensure the battery in the process of using the overcharge, discharge and short circuit, can avoid the protection board. Each time, in the process of use lithium ion battery overcharge, discharge and short circuit will reduce battery life. Serious directly discarded batteries! If there is no lithium ion battery protection board, lithium ion battery short circuit and overcharge will lead to bulge, severe leakage occurs, the stress relaxation, fire or explosion, and so on and so forth. , of course, if the design of lithium-ion battery protection board is bad, can damage the battery, but the purpose is to protect the battery protection board, prevent the battery before it is stable, so now use, put in lithium ion battery actually afraid of overcharge when considering without protection board. Lithium ion battery protection board's role is to protect the rechargeable battery of battery core, stability and stability, to maintain the battery in the process of charging and discharging on the performance of the battery circuit system plays an important role. 1. The overcharge protection function: the overcharge protection function is when reaches a certain voltage ( Hereinafter referred to as the overcharge check voltage) When ban charger to charge. Namely shutoff overcharge MOS tube, stop charging. 2. Over discharge protection function: over discharge protection function is in the lithium ion battery voltage lower stops to load discharge. Close control over discharge MOS tube, prohibit the discharge. The process check and overcharge when action is just the opposite. 3. The over-current protection function: over current protection function is stop to load when consuming large current discharge. This function is to protect the battery and the purpose of the MOS tube, guarantee the stability of the lithium ion battery in the working status. After flow check, will resume normal after the battery from the load, can charge or discharge. 4. Short circuit protection function: in addition to control IC, there is another important element of the circuit and MOSFET, have the effect of switch in the circuit. Because it directly in series between the battery and the external load, so it's on resistance have an impact on the performance of the battery. When choose MOSFET, the conduction resistance is very small, small battery internal resistance, carrying capacity is strong, discharge with low power consumption. When your battery accidental short-circuit protection board will be automatically closed in milliseconds, not electricity. Conclusion: about lithium batteries battery protection board installation method we introduce here, more information please also of focusing on our lithium battery manufacturers!
