Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model carries out the technical scheme in the embodiment of the utility model
Clear, complete description, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model proposes a kind of base station power battery management systems.
Referring to Figures 1 and 2, base station power battery management system, including charger module, battery management module, charge and discharge
Management module, LED display module and PC communication module, battery management module respectively with management of charging and discharging module, LED display module
Connected with PC communication module, PC communication module be connected with the low power consumpting state for waking up battery management module wake-up module and
For acquiring the communication module of battery data.
It should be understood that charger module turns DC module by AC, is converted into 55V direct current when there is the input of 220V alternating current
Power input, the more existing flash driving circuit of this charger module are compared, and using negative switch function, save boosting driving portion
Point, safety is improved, while adding the combination of comparator AP4313 using power management chip LM5022, realizes constant current constant voltage
Output function, this design is a kind of innovative design, relative to flash driving price it is lower, meanwhile, production and test
It is more convenient.
In the present embodiment, battery management system management be 12 string batteries, it can be achieved that battery supervising and management in real time, protect
Demonstrate,prove the safety and availability of battery pack.
Communication module and wake-up module, RS-485 interface are the combinations using balance driver and differential receiver, are resisted altogether
The enhancing of mould interference performance, at the same it is current by RS485 and host computer, the Protection parameters of battery can be uploaded in real time, pass through base
The transmission stood can make Master Control Center obtain the power management message of each base station in real time, realize on-line monitoring and management.
Management of charging and discharging module: this circuit carries out management of charging and discharging using field-effect tube, its conducting resistance is small, and grid drives
Dynamic not need electric current, loss is small, and driving circuit is simple, carries protection diode, and heat resistance characteristic is good；This circuit has battery simultaneously
