Lithium iron phosphate battery pack structure design

　　The structural design of lithium iron phosphate batteries depends on PACK technology. Let's take a look at the characteristics of PACK technology of lithium iron phosphate batteries.

　　1. PACK technology structure characteristics

　　There are four PACK technical structure characteristics, namely firmness, seismic, conductivity, and heat dissipation.

　　2. PACK technology "eight consistent" configuration principles

　　The principle of "eight consistency" of the ACK technology is self -discharge, consistent voltage, consistent voltage, internal resistance, consistent capacity, consistent circulation life, the same platform, consistent constant current ratio, and consistent power. These eight principles can ensure that the capacity maintenance rate is still more than 80%after 8 years of normal use of lithium iron phosphate battery packs.

　　3. Vertical over -current, horizontal protection function

　　This function refers to the connected direction (vertical) battery in the battery pack. In the parallel direction (horizontal) of the battery pack (horizontal), the battery pack safety is protected by PCB boards (also called simple BMS) with a fuse. When a single battery cell is short -circuit, the fuse of the PCB board is cut off, and the working circuit is separated to protect. In this way, the battery pack can ensure that the battery pack can be safely charged, and the operation of the battery pack is safe under large current charging conditions.

　　4. Dialogue connection

　　This connection method allows all batteries of lithium iron phosphate battery packs to charge and discharge under the same condition to ensure that the working current of each cell is consistent and improve the life of the battery pack. It can not only ensure the safety of the battery pack, but also greatly improve the cycle life of the battery pack.

　　5. Seven -proof structure

　　Lithium iron phosphate battery pack has dustproof, waterproof, fireproof flame -retardant, leak -proof, anti -leakage below design, leak -proof oxygen and anti -impact.
