The intelligent high-power communication power source developed by our company is adapted to solve the problems of wide distribution of base stations, inadequate power laying and difficult maintenance of base stations. Adopting standardized modular design, which can stack battery modules according to different base station needs. The power supply uses BMS system to manage battery cells. It monitors the status of battery cells in real time, and uses intelligent power detection IC to detect the battery charge and discharge power. How much electricity. Through radio communication equipment such as wifi, it can be connected with mobile terminals such as mobile phones in real time, allowing users to more easily grasp the operating status and power storage of the equipment.
First, the design requirements of lithium battery packs for communication base stations:
According to customer requirements and specifications, the intelligent battery pack supporting the host is designed to carry security protocols such as communication protocols, intelligent power statistics, and battery temperature. Join WIFI radio communication technology, connect terminal control equipment.
Under the specific design parameters:
1) Cell styling requirements: lithium iron phosphate 48V 50Ah combination.
2) Structural design requirements: The appearance is exquisite, using 1.5mm cold-rolled plate to reinforce the ribs, and the surface is dusted. The front plate 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 power display. The SBS intelligent battery management system design is adopted to effectively manage the remaining power of the battery. Accurate LED power display can effectively display the remaining battery power to the user in the form of LED lights at an accurate percentage, so as to achieve efficient and intuitive purposes. WIFI radio communication technology. Connect the device to a wireless terminal phone, etc. View and control equipment in real time.
Design scheme of lithium battery pack for communication base station:
1) Aluminum alloy + sheet metal shell and battery holder: Sheet metal powder coating shell, surface stiffener design, well maintained the structural strength and appearance of exquisite, one-piece nickel belt, with plastic battery holder. The connection of the battery is well maintained. Reduce impedance. The chassis uses a standard 3U chassis, which has excellent general performance. Very good universal standard cabinet, can be combined to expand capacity at will. The standard foldable handle saves space and facilitates the handling of the battery pack.
2) Intelligent Fuel Gauge Protection Board (PCM): adopts SBS intelligent battery management system, uses advanced power calculation principles to accurately calculate the battery power, and reports the battery power information to the host through SMBUS from time to time. The protection function of the battery pack (generally refers to the lithium battery). Due to the chemical characteristics of the lithium battery itself, it is necessary to provide protection functions such as overcharge, overdischarge, short circuit, overcurrent, and overtemperature to avoid dangers such as combustion and explosion. Join WIFI radio communication technology, connect with mobile terminal in real time. You can check the device power, temperature and other information anytime, anywhere. Control equipment operation.
3) LED power display board: 3.5-inch liquid crystal display, showing all battery pack power, voltage, current, temperature, and other information. The LED power display lamp will protect the battery calculated by the intelligent fuel gauge according to the 20% power ratio The capacity is displayed intuitively for efficient and intuitive use by customers.
4) Overcurrent protection film (PTC): It is mainly designed for the secondary protection function. PTC resettable fuse has dual functions of overcurrent protection and automatic recovery. PTC in battery products can prevent high temperature battery discharge and unsafe large current from occurring.
