Introduction to the actual use of lithium iron phosphate battery packs in tower base stations

In view of the characteristics of the lithium battery pack, when setting the DC switching power supply of the base station, you only need to adjust the float voltage and equalizing voltage to the charging voltage required by the lithium battery pack (at the same time, it must be within the DC supply voltage range of the communication equipment) Because even if the lithium battery pack is in the charging state for a long time, due to its own BMS protection function, the battery performance will not change. For example: a base station backup battery pack, using 48V-300Ah ladder lithium iron phosphate battery pack, each battery is composed of 16 3.2V/100Ah single cells in series, of which the 300Ah battery is composed of 3 groups of 100Ah battery packs in parallel. Yes, each battery pack has a BMS control system, as shown in Figure 10. After installing the battery pack and supplementing the battery pack, the battery packs were respectively subjected to 0.33C10 online detection of discharge conditions. The detection scene is shown in Figure 11. A set of 300Ah battery pack capacity detection curve is shown in Figure 12. After detecting with the intelligent battery pack discharge meter, it is integrated into the DC power supply system online. At this time, the charging voltage of the switching power supply is set to 56.8V, and the charging current is limited to 30A per group.
