Include tetra- batteries of B11, B12, B13, B14, in addition to the controller being connected with the rectification unit.
Described tetra- battery series connection of B11, B12, B13, B14, to load supplying.
Check diode is provided with the battery series loop.
Described tetra- rectification units of M11, M12, M13, M14 respectively with described tetra- batteries of B11, B12, B13, B14 simultaneously
Connection.
The rectification unit output 48V DC voltages and 12V DC voltage, 12V DC voltage charge a battery, 48V
DC voltage powering load.
Compared with prior art, its advantage is the power supply system for communications that a kind of battery series-parallel connection of the present invention uses：
1st, by Novel Communication rectification unit, the one-to-one management of discharge and recharge is carried out to battery, reduced to battery
Coherence request, can be achieved different brands, new and old battery it is mixed.
2nd, single-unit battery damage need not change whole battery pack, and only single only damage battery is changed, carried
The high utilization rate of battery.
3rd, system can increase scale capacity at any time to be used in parallel, increase expense only cost of equipment and construction cost, cost
It is lower.
【Brief description of the drawings】
Fig. 1 is the schematic diagram of the present invention.
【Embodiment】
The following example is further explanation of the present invention, and the present invention is not limited in any way.
As shown in figure 1, the power supply system for communications that a kind of battery series-parallel connection of the present invention uses includes alternating current inlet wire unit 1, whole
Flow unit group, controller, battery pack and check diode 4.Rectification unit group includes tetra- rectification units of M11, M12, M13, M14
2, battery pack includes tetra- batteries 3 of B11, B12, B13, B14.
As shown in figure 1, rectification unit group is multigroup unit M11-Mn1, setting is actually needed according to the size of load capacity
The quantity of rectification unit group, it is made up of multiple communication power supply modules in parallel.M11, M12, M13, M14 in one rectification unit group
Four rectification units 2 are in parallel, tetra- rectification units 2 of M11, M12, M13, M14 in a rectification unit group respectively with an electricity
Tetra- batteries of B11, B12, B13, B14 3 are in parallel in the group of pond, and tetra- batteries 3 of B11, B12, B13, B14 are gone here and there in a battery pack
Connection.
As shown in figure 1, rectification unit 2 can export 48V DC voltages and 12V DC voltage, and when alternating current is normal, exchange
Wire inlet unit 1 introduces alternating current, and DC48V is converted into by AC220V by rectification unit 2,48V direct currents by dc bus,
The powering load after feeder switch.12V DC voltage is charged to B11, B12, B13, B14 battery 3.
As shown in figure 1, the inside of rectification unit 2 is provided with RS485 order wires, rectification unit 2 is connected by RS485 order wires and controlled
Device processed.Controller main function is each functional unit running situation and each functional unit in system to be controlled in monitoring system
