How to extend the life of the UPS battery pack?lithium trolling motor battery Processor

　　1. Regular inspection

　　Check the end voltage and internal resistance of each unit battery. For the 12V unit battery, if the end voltage difference between the battery of each unit exceeds 0.4V or the internal resistance of the battery is more than 80mq or more, the battery should be balanced to restore the internal resistance of the battery to the battery's internal resistance. And eliminate the end voltage imbalance between the batteries. The charging voltage at a balanced charging can be taken 13.5 ~ 13.8V. Most of the batteries that are well -balanced charging can be restored to less than 30mq.

　　During the operation of the PS power supply, the above -mentioned unevenness generated by the battery characteristics of each unit may rely on the charging circuit inside the UPS power supply to eliminate it. For groups, if they are not taken off in time, their unevenness will become more and more serious.

　　2. Re -floating charging

　　The PS power supply is stopped for more than 10 days. Before reorganizing, the UPS power supply should be activated without loading.

　　The IPS power supply has been in a fluttering state for a long time without discharge, which is equivalent to being in the state of "storage and standing". If this state lasted too long, causing the battery to be scrapped due to "storage for too long". It mainly manifested that the internal resistance of the battery increased, and the internal resistance could reach a few Q.

　　We found that at room temperature at 20 ° C, after 1 month of storage, the capacity of the battery available was about 97%of its rated value. If it was stored for 6 months, its available capacity became 80%of the rated capacity. If the storage temperature rises, its use capacity will be reduced.

　　Therefore, it is recommended that users should deliberately unplug the electricity input every 20 ° C to allow the UPS power supply to work in the state of energy from the battery to the inverter. However, this operation should not be too long. When the load is about 30%of the rated output, it can be discharged for about 10min.

　　3. Reduce depth discharge

　　The service life of electricity is closely related to the depth of its discharge. The lighter the load of the UPS power supply, the larger the capacity of the power -to -use capacity to the rated capacity when the municipal power supply is interrupted. In this case, when the UPS power supply is automatically shut down when the battery voltage is too low, the battery is being automatically shut down. The depth of discharge is deeper.
