Vorsichtsmaßnahmen für das Design von Lithium-Ionen-Batterien -Lithium-Ionen-Batterieausrüstung

1. The internal switch element is used inside the lithium -ion battery. When the temperature of the battery rises, the resistance value rises, and the temperature stops discharge after the temperature is too high.
2. Set up a battery outlet in the structure. When the inner pressure of the battery rises to a certain extent, the pores are automatically opened to keep the internal pressure on the internal pressure imbalance of the alert and cause the battery to burst.
3. Optimize the electrolyte system. At present, the main electrolytes on the market are critical with organic solvents. It is difficult to withstand high voltage of more than 4.5V. Inorganic composite electrolyte is the best way to improve battery safety.
When designing needs to use a lithium -ion battery product, we must protect the circuit design of the lithium ion battery, and we can design the charging circuit based on this. We will understand that lithium -ion batteries should do over -voltage charging protection, overvoltage discharge protection, override discharge protection, short -circuit protection, etc. Therefore, when we design a lithium -ion battery protection circuit, we must at least achieve the above protection function.(Lithium - Ion Battery Equipment)
The design of the lithium -ion battery charger should have a adaptive power path management function. When the system side uses the power supply restrictions of the input power supply, ensure that the lithium -ion battery can actively drive the discharge function, and at the same time provide the power required for the system. When the charger consumes small electricity, when the battery is lower than 3V, the IC should set the 10%preset current of the charging current.
Lithium-ion battery charger IC should have active power path management. This power path management requires that when the load-end current is loaded/uninstalled, the lithium ion battery charging current is realized in real time. Requirements to restrict and soft excitement functions.
