What are the important maintenance methods for lithium iron phosphate battery packs?

(1) The operating conditions of the lithium iron phosphate battery pack The requirements of the operating conditions of the lithium iron phosphate battery pack: According to the requirements of the battery conditions, the room temperature should not be higher than 55℃, and the temperature should be maintained at 0℃～55℃. between. Protect the battery from direct sunlight, and sun-facing windows should be shaded. Ensure that sufficient maintenance space is reserved between the lithium-ion battery packs. (2) Precautions for the use of lithium iron phosphate batteries Different specifications and different models of lithium iron phosphate battery packs should not be used in the same DC power supply system, and batteries with different levels of old and new batteries should not be mixed in the same DC power supply system. If there is a power and condition meeting monitoring system, the total voltage, current, cell module voltage, temperature, and capacity of the battery pack should be monitored in time through the dynamic meeting monitoring system and BMS. At the same time, through the battery monitoring device to understand the battery charging and discharging curve and performance, actual measurement is carried out on schedule, and the invention hinders real-time processing and punishment. (3) Items that are frequently checked for lithium iron phosphate batteries should be checked frequently to see if the poles and connecting strips of lithium iron phosphate batteries are loose. Whether there is damage, deformation or corruption. Whether the connection is loose, whether the battery case is damaged, leaking or deformed, and whether the temperature rise of the battery and the connection is abnormal. According to the technical parameters and on-site conditions provided by the manufacturer, check whether the voltage of the battery pack and single module meets the requirements, and check whether the charging current of the battery pack during intermittent floating charge is within the required range. Check whether the charging current limit value configuration of the battery pack is correct. Check whether the low-voltage alarm and high-voltage alarm configurations of the battery pack are correct. (4) The voltage requirements for equal charge and float charge operation of lithium iron phosphate batteries are generally configured as a single battery: 3.60～3.76V for intermittent charging voltage of lithium iron phosphate battery packs, and a high-voltage DC output voltage of 278V. Measure the battery pack voltage and the terminal voltage of the single battery every month to compare with the battery monitor display, and solve problems in real time.
