What are the requirements for the installation and maintenance of ladder lithium iron phosphate batteries

Ladder lithium iron phosphate battery installation and maintenance requirements1. The surface of the battery pack should be clean, without obvious deformation, no mechanical damage, and no rust on the interface contacts; the surface of the battery pack should have the necessary product identification, and the identification should be clear; the positive and The negative terminal and polarity should be clearly marked, and the wiring method should be front-out for easy connection; the power interface and communication (or alarm) interface of the battery pack should be clearly marked; 2. The 19-inch standard mechanical and electrical equipment of the stepped lithium battery pack The container shell, mounting frame or box of the unit should be made of metal material, and the structure is easy to carry; 3.In order to install the stepped battery for easy commissioning and later maintenance, the iron-lithium battery panel should be facing outwards, and the stepped battery should be reliably fixed to the battery rack. In the upper or integrated cabinet; 4, the step battery is laid out the step battery connection line, and the battery line is connected to the upper port terminal of the fuse copper bar in the power cabinet or the battery management circuit breaker, and the cable is labeled and identified; 5. Lay out the battery monitoring cable and connect the iron-lithium battery pack to the FSU-RS485 communication terminal; 6.The iron-lithium battery cascade battery is connected to the system. After all kinds of cables are connected, use a multimeter to test the output voltage of the battery. Make a record of the data of the switching power supply, adjust the output voltage of the switching power supply to the current voltage value of the battery; 7.Adjust the parameters of the switching power supply, after all kinds of cables are connected, use a multimeter to test the output voltage of the battery, and record the test data 8. Requirements for the operating environment of cascaded lithium iron phosphate batteries: According to the environmental requirements of the battery, the room temperature should not exceed 55 ℃, and the battery should be protected from direct sunlight. The sunshade windows should be shaded to ensure that sufficient maintenance space is reserved between the battery packs. 9. Matters needing attention in the use of ladder lithium iron phosphate batteries The total voltage, current, cell voltage SOC, SOH, and temperature of the battery pack are monitored in real time through the dynamic loop aggregation monitoring system and BMS. At the same time, the battery charging and discharging curve and performance are known through the battery monitoring device, and the regular measurement is performed to solve the fault in time; 10.Items that are often checked for the ladder lithium iron phosphate battery: The terminal connection line of the ladder lithium iron phosphate battery module should be checked frequently ( Bar) Is it loose, damaged, deformed, or corroded; Is the connection loose, whether the battery module is damaged, leaking and deformed, whether the temperature rise of the battery and the connection is abnormal; whether the BMS data line is in contact ; Carry out an alarm test on the output fuse temperature check and signal fuse of the battery pack. According to the technical parameters and on-site environmental conditions provided by the manufacturer, check whether the total voltage and cell voltage of the battery pack meet the requirements through the BMS system, and test whether the charging current of the battery pack is within the required range during intermittent charging. Test whether the settings of the charging voltage and current limit value of the switching power supply and battery pack are correct. Test whether the low-voltage alarm, high-voltage alarm, high-temperature alarm and other settings of the battery pack are correct.
