2K power module 50AH lithium battery module
Figure 2-1-1 shows the outline diagram of the small cell power system.
2.2 Principle of work
Figure 2-2-1 is the schematic diagram of small cell power .
The small cell power system adopts the single-phase three-wire of AC input. AC is changed into
stable direct current to positive and negative discharge of the system after rectifying, filtering, stabilizing
and other links of the rectifier. The system has a battery interface, the battery via battery fuse, shunt (test
battery current) and the output of the rectifier module in parallel, when AC power failure, The power
supply from customer DC load is by DC PDB .
AC distribution state, rectifier state, battery state, DC shunt state, customer power consumption,
etc. are all detected or controlled by the controller. Bluetooth unit and remote monitoring unit are
configured in the system. At the nearly point, the relevant information of the system can be check
by mobile APP;At the remote point, the system information can be monitored by remotely PC system .
