Theintelligent high-power communication power source developed by our company isadapted to solve the problems of wide distribution of base stations, inadequatepower laying and difficult maintenance of base stations. Adopting standardizedmodular design, which can stack battery modules according to different basestation needs. The power supply uses BMS system to manage battery cells. Itmonitors the status of battery cells in real time, and uses intelligent powerdetection IC to detect the battery charge and discharge power. How muchelectricity. Through radio communication equipment such as wifi, it can beconnected with mobile terminals such as mobile phones in real time, allowingusers to more easily grasp the operating status and power storage of theequipment.
First,the design requirements of lithium battery packs for communication basestations:
Accordingto customer requirements and specifications, the intelligent battery packsupporting the host is designed to carry security protocols such ascommunication protocols, intelligent power statistics, and battery temperature.Join WIFI radio communication technology, connect terminal control equipment.
Underthe specific design parameters:
1)Cell styling requirements: lithium iron phosphate 48V 50Ah combination.
2)Structural design requirements: The appearance is exquisite, using 1.5mmcold-rolled plate to reinforce the ribs, and the surface is dusted. The frontplate is made of aviation-grade aluminum alloy and is anodized and brushed.Surface laser engraved logo.
3)Circuit design requirements: accurate power management + accurate LED powerdisplay. The SBS intelligent battery management system design is adopted toeffectively manage the remaining power of the battery. Accurate LED powerdisplay can effectively display the remaining battery power to the user in theform of LED lights at an accurate percentage, so as to achieve efficient andintuitive purposes. WIFI radio communication technology. Connect the device toa wireless terminal phone, etc. View and control equipment in real time.
Designscheme of lithium battery pack for communication base station:
1)Aluminum alloy + sheet metal shell and battery holder: Sheet metal powdercoating shell, surface stiffener design, well maintained the structuralstrength and appearance of exquisite, one-piece nickel belt, with plasticbattery holder. The connection of the battery is well maintained. Reduceimpedance. The chassis uses a standard 3U chassis, which has excellent generalperformance. Very good universal standard cabinet, can be combined to expandcapacity at will. The standard foldable handle saves space and facilitates thehandling of the battery pack.
2)Intelligent Fuel Gauge Protection Board (PCM): adopts SBS intelligent batterymanagement system, uses advanced power calculation principles to accuratelycalculate the battery power, and reports the battery power information to thehost through SMBUS from time to time. The protection function of the batterypack (generally refers to the lithium battery). Due to the chemicalcharacteristics of the lithium battery itself, it is necessary to provideprotection functions such as overcharge, overdischarge, short circuit,overcurrent, and overtemperature to avoid dangers such as combustion andexplosion. Join WIFI radio communication technology, connect with mobileterminal in real time. You can check the device power, temperature and otherinformation anytime, anywhere. Control equipment operation.
3)LED power display board: 3.5-inch liquid crystal display, showing all batterypack power, voltage, current, temperature, and other information. The LED powerdisplay lamp will protect the battery calculated by the intelligent fuel gaugeaccording to the 20% power ratio The capacity is displayed intuitively forefficient and intuitive use by customers.
4)Overcurrent protection film (PTC): It is mainly designed for the secondaryprotection function. PTC resettable fuse has dual functions of overcurrentprotection and automatic recovery. PTC in battery products can prevent hightemperature battery discharge and unsafe large current from occurring.
