Working process and design points of protection board for lithium iron phosphate battery pack

Working process of lithium iron phosphate battery pack protection board: When the cell voltage is between 2.5V and 4.3V, the first and third pins of DW01 both output high level (equal to the supply voltage), and the second pin voltage is 0V . At this time, the voltage of pin 1 and pin 3 of DW01 will be applied to pins 5 and 4 of 8205A respectively. The two electronic switches in 8205A are in the conducting state because their G poles are connected to the voltage from DW01, that is Both electronic switches are in the open state. At this time, the negative pole of the battery and the P- terminal of the protection board are equivalent to a straight connection, and the protection board has a voltage output. The design of lithium iron phosphate battery pack protection board should consider the following points: lithium iron phosphate battery.pngA, the design of lithium iron phosphate battery pack protection board should ensure reliability and working stability. Over-current parameters retain at least 30% technical margin. B. The designed product should be easy to detect. C. The design of the lithium battery pack protection board should be easy to process and debug, and the process should be simplified. D. Lithium iron phosphate battery products should be easy to install. E. The design of the lithium battery pack must meet the size requirements. F. The design should facilitate the purchase of devices. The device used cannot be too special. G. The design of lithium battery protection board should consider the cost. H. The design should fully consider the heat dissipation and the placement of the heat sink. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
