What is important for lithium battery protection circuit planning?

Lithium battery overcharge and overdischarge will affect the battery life. Pay attention to the charging voltage and charging current of the lithium battery. Then select the appropriate charging chip. Pay attention to the overcharge, overdischarge, short circuit protection and other issues of lithium batteries. Lithium battery protection circuit planning will have to pass many tests in the future. When we plan to use lithium battery products, we need to plan the protection circuit of the lithium battery, and then we can plan the charging circuit on this basis. Lithium batteries require over-voltage charging protection, over-voltage discharge protection, over-current discharge protection, short-circuit protection, etc. Therefore, when we plan the lithium battery protection circuit, we must at least achieve the above protection functions. The lithium battery protection board also has the function of protecting the battery and guarding against battery overcharging. 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 a full level, the internal circuit of the lithium battery protection board will automatically cut off the external fast charging power supply. So that external power cannot enter the battery. This is exactly the principle that the lithium battery protection board protects the battery from overcharging. Lithium battery protection IC's ultra-small package and few external equipment requirements make it widely used in the planning of single-cell lithium battery protection circuits.
