Maintenance and maintenance of lithium batteries for photovoltaic energy storage systems, off-grid energy storage systems, and UPS systems

　　Lithium batteries are much more expensive than lead-acid batteries. How to maintain and maintain lithium batteries has always been the focus of consumer concern.

　　So, what is the correct maintenance and maintenance of the lithium batteries of photovoltaic energy storage systems, off-grid energy storage systems, and UPS systems?

　　1. Environmental requirements for the use of lithium batteries

　　▲The placement of the cabinet with lithium batteries must be stable.

　　▲The lithium battery must be far away from heat sources, avoid direct sunlight, and do not approach corrosive objects.

　　▲The working environment of lithium battery needs to maintain normal temperature and humidity.

　　▲Keep clean in use.

　　2. The size and characteristics of the load must be considered when using lithium batteries

　　The rated output power of the lithium battery is an important parameter of how much power load the product can drive. In order to prolong the service life of the lithium battery, the lithium battery should not be operated under full load for a long time.

　　Backup-type lithium batteries generally select a load of 50% to 80% of the rated power, and on-line lithium batteries that are used more frequently generally select a load of 80% to 90% of the rated power.

　　3. Other precautions for lithium batteries

　　▲Lithium batteries are electronically protected by BMS, but after being discharged to the protection shutdown, restarting is not allowed, otherwise it will easily cause the battery to over-discharge.

　　▲For long-term storage of lithium batteries, the lithium batteries should be charged and discharged every 3 to 6 months to ensure that the chemical substances inside the lithium batteries remain active.

　　▲Regularly clean and maintain lithium batteries. .

　　The above is an introduction to the maintenance and maintenance of lithium batteries.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data centers and other industries.
