It is connected, moreover, string is equipped with diode D1~Dn in every discharge paths, the anode of diode is opened by the control of corresponding branch
It closes and is connected with the anode of corresponding battery modules, cathode is connected with base station equipment.
The electric energy of battery module passes through discharge paths and electric discharge main line, supplies base station equipment through charge and discharge branch
Electricity.
Each battery modules are when under discharge condition, since the voltage between each battery modules may be unequal,
It is so likely to occur the case where high battery module of voltage charges appearance to the low battery modules of voltage at this time, which is battery
Circulation phenomenon between mould group, will will cause the loss of battery system internal component at this time.The generation of the phenomenon in order to prevent,
Therefore a discharge paths are connected between electric discharge main line and charge and discharge branch, string sets a diode in the discharge paths, makes
It obtains when battery modules are under discharge condition, electric current can only be flowed out from battery modules, and cannot flow into battery modules.
Each battery modules are correspondingly arranged on branch way control switch K1~Kn, so that battery modules are too high or too low in electricity
In the case where, it can be opened or closed by controlling corresponding branch way control switch, to realize each battery modules in charging process
Between electric voltage equalization.

The status information of block.
The charging control switch KV1 of above-mentioned introduction, discharge control switch KV2, branch way control switch K1~Kn all can for after
Electric appliance can also be other controllable switch.
The course of work of the communication base station system is described in detail below.
As shown in Fig. 2, being the battery system discharge process flow chart of the communication base station system.
Firstly, under whole system normal operating conditions, control is put so that charging control switch KV1 is in an off state
Electric control switch KV2 is in closed state, and branch way control switch K1~Kn of each battery modules is also at closed state, battery
Each battery modules in system are powered by diode to base station equipment, simultaneously, it is ensured that do not fill mutually between battery modules
The circulation of electric discharge generates.
Meanwhile battery modules monitoring module is acquired monitoring to information such as voltage, the electric currents of each battery modules, and will
The information of acquisition passes to battery system main control module.Battery management system main control module is according to the entire battery of these data-evaluations
The remaining capacity of system, and according to remaining capacity number determine whether start battery discharge protection strategy.When battery capacity mistake
When low, the control of battery management system main control module disconnects discharge control switch KV2.
Moreover, when battery modules monitoring module detects that wherein a certain battery modules come across the surplus of other each battery modules
When remaining electricity difference is larger, the minimum corresponding branch way control switch of battery modules of remaining capacity is disconnected, to stop the battery mould
Group discharges to base station equipment.
As shown in figure 3, being the communication base station system to battery system charging process flow chart.
Firstly, being in power output state and battery mould when battery management system main control module gets power conversion module
When the electricity of group is less, it is closed charging control switch KV1.
Then, the voltage and charging current information of battery modules monitoring module acquisition battery modules, according to battery modules electricity
Pressure and charging current calculate the remaining capacity of the battery modules, and the information is exported and gives battery management system main control module.Together
When, battery management system main control module judges whether to need disconnected branches control according to the data that battery modules monitoring module exports
Switch, if desired disconnects, then issues open command to corresponding branch way control switch.
After all battery modules reach full of electricity condition, battery management system main control module disconnects charge control and opens
KV1 is closed, and is sent to all branch way control switch and disconnects switch order.
Moreover, the system can also dynamically add battery modules, flow chart is as shown in Figure 4.
When battery system needs dilatation, a new battery modules n+1 can be directly added, at this time battery management system master
Control module automatic identification and will manage new battery modules；Meanwhile being correspondingly arranged on corresponding battery modules monitoring mould
Block n+1.
The remaining capacity information for the battery module that battery modules monitoring module n+1 will test is sent to battery management system
Main control module, battery management system main control module finds this new battery modules and other battery modules, and there are biggish consistent
When gender gap, it can charge during charging to the battery system to new battery modules, so that itself and other batteries
Mould group is consistent.
