The safety and reliability of lithium batteries for communication energy storage can be ensured in a number of ways:
1.Battery selection and quality control:
Selection of high-quality electric core: electric core is the core component of the battery, and its quality directly determines the safety and reliability of the battery. Products from well-known brands and reputable battery cell suppliers should be selected, which usually undergo strict quality testing and verification, and have high stability and consistency. For example, the battery cell products from well-known battery manufacturers such as Ningde Times and BYD are highly recognized in the market.
Compliance with relevant standards and certifications: Ensure that the selected lithium batteries comply with relevant national and industry standards and certification requirements, such as GB/T 36276-2018 “Lithium-ion Batteries for Electric Energy Storage” and other standards. These standards make clear provisions for battery performance, safety and other aspects, and a battery that meets the standards can ensure safety and reliability in communication energy storage applications.
2.Battery Management System (BMS):
Accurate monitoring function: BMS is able to monitor the voltage, current, temperature, internal resistance and other parameters of the battery in real time, so as to find out the abnormal situation of the battery in time. For example, when the battery temperature is too high or the voltage is abnormal, the BMS can immediately issue an alarm and take corresponding measures, such as reducing the charging current or stopping charging, to prevent the battery from thermal runaway and other safety issues.
Equalization management: As the performance of each cell in the battery pack may differ during use, resulting in overcharging or overdischarging of some cells, which affects the overall performance and life of the battery pack, the equalization management function of the BMS can equalize the charging or discharging of the cells in the battery pack, so as to keep the state of each cell consistent, and improve the reliability and life of the battery pack.
Safety Protection Function: BMS is equipped with various safety protection functions such as overcharge protection, overdischarge protection, overcurrent protection, short circuit protection, etc., which can cut off the circuit in time when the battery is in an abnormal situation and protect the safety of the battery and communication equipment.
3.Thermal management system:
Effective heat dissipation design: communication energy storage lithium batteries generate heat during charging and discharging, and if the heat cannot be emitted in time, it will lead to an increase in the battery temperature, affecting the performance and safety of the battery. Therefore, it is necessary to use effective heat dissipation design, such as air cooling, liquid cooling and other heat dissipation methods, to control the temperature of the battery within the safe range. For example, in large-scale communication energy storage power stations, liquid cooling heat dissipation system is usually used, which has better heat dissipation effect and can ensure the temperature uniformity of the battery.
Temperature monitoring and control: In addition to heat dissipation design, it is also necessary to monitor and control the temperature of the battery in real time. By installing temperature sensors in the battery pack, the temperature information of the battery can be obtained in real time, and when the temperature exceeds the set threshold, the heat dissipation system will be activated or other cooling measures will be taken to ensure that the temperature of the battery is always within the safe range.
4.Safety protection measures:
Fireproof and explosion-proof design: Adopt fireproof and explosion-proof materials and structural design, such as using flame-retardant materials to make the battery shell, and setting up fireproof isolation zones between the battery modules, etc., so as to prevent the battery from triggering a fire or an explosion in the event of thermal runaway. At the same time, equipped with appropriate fire-fighting equipment, such as fire extinguishers, firefighting sand, etc., in order to be able to extinguish the fire in a timely manner in the event of a fire.
Anti-vibration and anti-shock design: communication equipment may be subject to external vibration and shock, so the communication storage lithium battery needs to have good anti-vibration and anti-shock performance. In the structural design and installation of the battery, the requirements of anti-vibration and anti-shock should be taken into account, such as the use of reinforced battery shells, reasonable installation and fixing methods to ensure that the battery can work properly in harsh environments.
5.Production process and quality control :
Strict production process: follow the rigorous production process to ensure that the battery production process meets the quality requirements. During the production process, strict quality control is carried out for each link, such as electrode preparation, cell assembly, battery packaging, etc., to ensure the consistency and reliability of the battery.
Quality testing and screening: comprehensive quality testing and screening of the produced batteries, including appearance inspection, performance testing, safety testing and so on. Only those batteries that have passed the testing and screening can enter the market for sale and application, thus ensuring the quality and safety of lithium batteries for communication energy storage.
6.Full life cycle management:
Operation monitoring and maintenance: real-time monitoring and regular maintenance of the battery during its use. Through the remote monitoring system, you can obtain real-time information about the battery's operation status and find and solve problems in time. Regular maintenance includes cleaning, checking and calibrating the battery to ensure the performance and safety of the battery.
Decommissioning management: When the battery reaches the end of its service life or its performance decreases to the point where it cannot meet the communication energy storage demand, it needs to be decommissioned. In the decommissioning process, the battery should be recycled, disassembled and disposed of in accordance with relevant regulations and standards to avoid pollution to the environment, and at the same time, some of the useful materials can be recycled to reduce costs.
7.Well-developed emergency response plan:
Formulation of emergency response plan: For possible safety accidents, formulate a perfect emergency response plan, including emergency treatment measures for fire, explosion, leakage and other accidents. The emergency plan should clarify the duties and tasks of each department and personnel to ensure that the accident can be handled quickly and effectively when it occurs.
Regular drills: Regular drills of the emergency plan are organized to improve the emergency handling ability and cooperative ability of relevant personnel. Through drills, problems and deficiencies in the emergency plan can be found, and timely improvements and perfections can be made.
