Iron phosphate battery protection board function -Lithium - Ion Battery Equipment
Lithium iron phosphate ion battery protection board function, is it suitable for fast charging for lithium iron phosphate ion batteries? At present, most of the power lithium batteries in my country are lead -acid batteries, but the battery has disadvantages such as smaller capacity, large volume, and high pollution. The study of its protection circuit is also an important development direction. What are the protective board functions of lithium iron phosphate ion batteries? Is lithium iron phosphate cells suitable for fast charging?
Lithium iron phosphate ion battery protection board function
1. The protective board has the function of over -charging voltage protection
The maximum limit voltage of a single lithium -ion battery is set to 4.2V. When the charging voltage reaches this value, the circuit board is limited to charging, and the indicator light of each single battery is displayed.
2. The protective board has over -voltage protection function
When working on power lithium batteries, it consumes electricity and reduces the battery voltage. If it exceeds its range, it will affect the life of the battery. The underwriter protection value of a single lithium -ion battery is set to 2.0V. When the value is lower than this value, the protective board protects the battery, so that the lithium -ion battery pack will automatically stop working.(Lithium - Ion Battery Equipment)
3. This protective board has an overcurrent protection function
When the working current exceeds the rated value, the lithium -ion battery protective board sends a signal to stop the lithium -ion battery pack.
4. This protective board has a short -circuit protection function
When the external reason is caused by various reasons, the lithium -ion battery protection board protects the lithium -ion battery pack to prevent damage to the lithium -ion battery group.
5. This protective board has temperature protection function
When the working temperature of the battery exceeds the rated value, the work of the lithium -ion battery pack is stopped by this line board to avoid accidents and protect the battery pack and users.
Lithium iron phosphate ion battery is suitable for fast charging
There are two sides of this problem. From the perspective of materials, the conductivity of lithium iron phosphate materials is relatively low. It is only one percent of the ternary material. The material optimization of the material of the lithium iron phosphate battery must be optimized to meet the needs of fast charging.
Traditional lithium iron phosphate has poor conductivity, and fast charging is prone to heat. After the side reaction is more, the circulation naturally deteriorates and affects the battery life. Therefore Lithium iron phosphate is very promising in terms of fast charging. At the same time, the fast charge battery is not only dynamic, but also because the energy density is lower than that of non -fast charging, the energy density is lower, the electrolyte is more, and the circulation becomes better.
In terms of solving the mileage of new energy vehicles, the power replacement mode, increased battery loading and fast charging have become three major directions. From the perspective of comprehensive operating costs, fast charging is a very suitable operating vehicle that is very suitable Essence There is no need to over -press the energy density of the battery, and the power replenishment can be completed in the operation of the operation.
In the fast charging market, lithium titanate and lithium manganate each occupy a certain share, and the development of lithium iron phosphate this year is also remarkable and achieved rapid development. We are convinced that with the development of the lithium -ion battery industry in my country, more and more industries will pay attention to the protection of the circuit of lithium -ion batteries. And hope that through the introduction of this essay, the domestic electric power industry will have a new profound understanding and understanding of the lithium -ion battery protection board.
