Key technical standards for lithium iron phosphate power lithium battery packs for communications

The key technical standards of lithium iron phosphate power lithium battery packs for communications: 1. Operating temperature field. Lithium battery packages are used under the following operating temperature standards: battery charging environment temperature: −10~55°C; discharge environment temperature: −20~60°C; Second, it is the characteristics of electric equipment. The key characteristics inside the lithium battery pack are the same. Each lithium battery cell in the lithium battery pack should be processed and manufactured by the same processing factory, with the same structure and composition, and comply with the following regulations: 1. The maximum and minimum operating voltage of electrostatic induction short-circuit between the lithium batteries in the rechargeable battery pack The difference between the values u200bu200bshall not exceed; 2. The difference between the highest value and the smallest value of the resistance in the static data of each lithium battery cell in the rechargeable battery control module should be consistent: less than ten meters W, and the square root of error does not exceed ten meters W, more than ten meters W 5% of the average value; 3. The difference between the larger volume and the minimum volume between the cores in the rechargeable battery touch group shall not exceed the average value ±1%. 3. Possession of energy storage technology. The battery capacity should not be less than 95% of the short-circuit capacity. 4. Cycle time service life. The service life of the battery's circulatory system should be 800~2000 times. 5. High temperature will accelerate the embrittlement period. After the battery is charged and discharged in accordance with the regulations, there should be no significant deformation, rust, smoke or explosion in appearance, and the test cycle time shall not be less than 52 times. Sixth, electromagnetic compatibility detection. 1. Anti-interference of electrostatic induction charging and discharging. The lithium battery pack should meet the requirements of GB/Level 4, after the test, the appearance should have no significant deformation, liquid leakage, smoke or explosion, and be able to work normally. 2. The degree of transmission interference. The lithium battery pack should meet the requirements of YD/T983-1998 Class B. After the test, there should be no significant deformation, liquid leakage, smoke, explosion, etc., and it should be able to work normally. 3. Restrictions on the interference of radiation sources. The lithium battery pack should meet the requirements of YD/T983-1998 Class B. After the test, there should be no significant deformation, liquid leakage, smoke, explosion, etc., and it should be able to work normally. 4. Impact resistance (impact resistance). The lithium battery pack should meet the requirements of GB/Level 4, after the test, the appearance should have no significant deformation, liquid leakage, smoke or explosion, and be able to work normally. 7) Battery management purpose. Seven, the accuracy of the displayed information. The lithium battery pack is equipped with a dedicated rechargeable battery intelligent management system (BMS). The deviation between the various variable values u200bu200bof the BMS display information and the detailed variable values u200bu200bof the rechargeable battery should be considered in Table 1.
