How to maintain lithium iron phosphate battery? Next, we will take you to know where daily maintenance of lithium iron phosphate battery is required?

(1) Working environment requirements of lithium iron phosphate battery pack: according to the environmental requirements of the battery, the room temperature should not exceed 55 ℃, and it is recommended that the ambient temperature be kept between 0 ℃ and 55 ℃. In order to prevent direct sunlight from the battery, windows facing the sun should be shaded. Ensure that there is enough maintenance space between lithium ion battery packs.

(2) Precautions for using lithium iron phosphate batteries Different specifications and models of lithium iron phosphate batteries shall not be used in the same DC power supply system. Batteries of different old and new levels shall not be mixed in the same DC power supply system. If there is a centralized power supply and environment monitoring system, the total voltage, current, single module voltage, temperature and capacity of the battery pack shall be monitored in real time through the dynamic environment centralized monitoring system and BMS. At the same time, the charging and discharging curve and performance of the battery are known through the battery monitoring device, and the actual measurement is carried out regularly to find and deal with faults in time.

(3) For the regular inspection items of lithium iron phosphate battery, check whether the electrode and connecting strip of lithium iron phosphate battery are loose. Whether there is damage, deformation or corrosion. Whether the connection is loose, whether the battery shell is damaged, leaked, deformed, and whether the battery temperature rise and connection are abnormal. According to the technical parameters provided by the manufacturer and the on-site environmental conditions, check whether the voltage of the battery pack and single module meets the requirements, and whether the charging current of the battery pack during intermittent floating charge is within the required range. Check whether the charging current limit of the battery pack is set correctly. Check whether the low voltage alarm and high voltage alarm settings of the battery pack are correct.
