Understanding the various parameters of lithium batteries: Easy selection of lithium batteries
Lithium batteries have been widely used in various fields. From smartphones, tablets to electric vehicles, lithium batteries are an indispensable source of energy. To ensure the stable and safe operation of lithium batteries, we need to understand and pay attention to their basic parameters. These parameters not only reflect the performance of lithium batteries, but also determine their applicability and service life. Here we will elaborate on the basic parameters of lithium batteries, providing a reference for your better understanding and use of lithium batteries. 1. Detailed explanation of basic parameters of lithium batteriesl Rated capacityRated capacity refers to the maximum amount of electricity that a lithium battery can provide under specific conditions, usually measured in milliampere hours (mAh) or ampere hours (Ah). This parameter reflects the battery's ability to store electricity and determines the length of time the battery can support device operation. When choosing a lithium battery, the required capacity should be determined based on the device's power consumption and expected usage time. l Rated voltageRated voltage refers to the voltage of a lithium battery at full charge, usually measured in volts (V). The rated voltage of lithium batteries is generally 3.7V or 4.2V, and different models of lithium batteries may vary. Understanding the rated voltage of the battery helps us choose the appropriate charger and electrical equipment to ensure that the battery can function properly. l Internal resistanceInternal resistance refers to the resistance inside a lithium battery, which affects the charging and discharging efficiency and heating situation of the battery. The smaller the internal resistance, the higher the charging and discharging efficiency of the battery, and the smaller the heat generated. Therefore, when choosing lithium batteries, it is advisable to choose products with lower internal resistance as much as possible. l Cycle lifeCycle life refers to the number of times a lithium battery can undergo charging and discharging cycles. The cycle life of lithium batteries is related to their structure and materials, generally ranging from hundreds to thousands of cycles. Understanding the cycle life of batteries helps us to arrange the usage and replacement cycle of batteries reasonably, and avoid excessive battery loss. l Self discharge rateSelf discharge rate refers to the rate at which a lithium battery self discharges when not in use, usually expressed as a percentage per month. The self discharge rate of lithium batteries is related to factors such as materials, manufacturing processes, and storage conditions. Understanding the self discharge rate of batteries helps us to arrange their storage and usage time reasonably, avoiding the loss of battery power due to prolonged inactivity. l Working temperature rangeThe working temperature range refers to the temperature range within which lithium batteries operate normally. Lithium batteries are sensitive to temperature, and high or low temperatures can affect their performance and lifespan. Therefore, when using lithium batteries, it is important to ensure that they operate within a suitable temperature range to avoid battery damage or safety accidents. l Charging timeCharging time refers to the time required for a lithium battery to go from empty to full, usually measured in hours. The charging time is influenced by various factors such as the power of the charger, the capacity of the battery, and the charging method. Understanding the charging time of batteries helps us to plan our charging schedule reasonably and avoid situations of overcharging or undercharging. l Discharge depthDischarge depth refers to the ratio of the maximum capacity reached by a lithium battery during discharge to its rated capacity. The deeper the discharge depth, the shorter the battery life may be. Therefore, when using lithium batteries, deep discharge should be avoided to extend the battery's service life. l Termination voltageThe termination voltage refers to the voltage threshold that lithium batteries should not exceed during charging and discharging. When charging, the battery voltage should not exceed the maximum termination voltage; When discharging, the battery voltage should not be lower than the minimum termination voltage. Exceeding these thresholds may cause damage to the battery, affecting its performance and lifespan. Therefore, when using lithium batteries, it is important to ensure that the charging and discharging processes are carried out within the appropriate voltage range. l Energy densityEnergy density refers to the amount of energy that a lithium battery can store per unit volume or weight, typically measured in watt hours per kilogram (Wh/kg) or watt hours per liter (Wh/L). The higher the energy density, the more energy the battery can store in the same volume or weight, which is particularly important for electronic devices that require long working hours or are convenient to carry. 2. How to choose a suitable lithium battery When choosing a lithium battery, we need to comprehensively consider the above parameters. Firstly, determine the required rated capacity based on the power consumption and expected usage time of the device; Secondly, ensure that the rated voltage, internal resistance, and cycle life of the selected lithium battery meet the equipment requirements; At the same time, attention should also be paid to the self discharge rate, operating temperature range, and charging time of lithium batteries to ensure their stable and safe operation. As a professional battery supplier, Be Power is committed to providing customers with high-quality and customized solutions；We are the number one Chinese battery supplier delivered to automotive OEM in Brazil.We offered battery for over 800K set HESS systems; Our battery systems are warmly welcomed in over 30 countries applied on electricTrucks，electric light vehicles，electric UTV, electric sweepers, container energy storage systems, 215Kwh commercial and industrial energy storage systems etc. With top-notch technical team in China we are providing the toughest technical and highest level safety products. 3. Conclusion The basic parameters of lithium batteries cover multiple aspects, which not only reflect the performance characteristics of lithium batteries, but also determine their applicability and service life. When selecting and using lithium batteries, we should fully understand these parameters and make reasonable combinations and choices based on actual needs. At the same time, we should also follow the correct charging and discharging methods to avoid damage to the battery caused by adverse factors such as overcharging and discharging and high temperatures. By using lithium batteries scientifically and reasonably, we can ensure that they provide stable and safe power support for our equipment.

Eight major differences between air cooling and liquid cooling in energy storage systems
1.Different cooling principlesAir cooling is the process of removing heat through the flow of air, which lowers the surface temperature of the equipment. The advantages of air-cooled heat dissipation are simple structure and low cost, but its heat dissipation effect is greatly affected by factors such as environmental temperature and air circulation, and is not suitable for high-power and high-density equipment. Liquid cooling heat dissipation is the process of removing heat through liquid circulation, which lowers the internal temperature of the equipment. The advantages of liquid cooling are good heat dissipation effect and high stability, but its cost is high and it requires maintenance of the liquid circulation system.2. Different applicable scenarios Air cooling systems are suitable for energy storage systems of various scales and types, especially in outdoor environments with better applicability. It is currently the most widely used cooling technology, applied in industrial refrigeration, communication base stations, data centers, temperature control scenarios, etc., with relatively high technological maturity and reliability. Especially in low to medium power scenarios, air cooling remains the mainstream. Liquid cooling systems are also suitable for various scales and types of energy storage systems, especially for large-scale, high energy density energy storage projects. The advantages of battery packs are particularly evident in situations with high energy density, fast charging and discharging speeds, and large environmental temperature changes. 3. Different design complexityThe design of air-cooled energy storage systems is relatively simple, mainly involving the installation of heat dissipation fans and the design of air circulation paths. The core of air-cooled systems is the air conditioning and air ducts, which are used for cooling and exchanging heat; Liquid cooling design is usually more complex and requires consideration of issues such as the layout of the liquid circulation system, pump selection, coolant circulation, and maintenance. 4. Different heat dissipation effectsThe heat dissipation effect of air-cooled cooling is greatly affected by factors such as environmental temperature and air circulation, and generally cannot meet the heat dissipation needs of high-power equipment. The cooling effect of liquid cooling is better, which can effectively reduce the internal temperature of the equipment, improve the stability and lifespan of the equipment. 5. Different operating power consumptionThe composition of power consumption is different, and the main power consumption of air cooling is air conditioning+electrical compartment fan; The main power consumption of liquid cooling is the combination of liquid cooling units and electrical compartment fans (some manufacturers use whole machine liquid cooling). Under the same conditions and maintaining the same temperature, the power consumption of air cooling is higher than that of liquid cooling. 6. Different costs and maintenanceThe cost of air-cooled heat dissipation is relatively low and maintenance is simple. However, due to its limited heat dissipation effect, it may be necessary to increase the number of heat sinks or increase the fan speed to improve the heat dissipation effect, thereby increasing energy consumption and maintenance costs. The cost of liquid cooling is relatively high and requires maintenance of the liquid circulation system. However, due to its good heat dissipation effect and high stability, it can reduce equipment failure rate and maintenance costs. In the long run, its overall cost may be lower than that of air-cooled heat dissipation. 7. Different levels of noise and space occupancyThe noise generated by air-cooled cooling is relatively low and has a relatively small impact on the environment. But due to the need to install fans and heat sinks, it may take up some space. The noise generated by liquid cooling is relatively high and has a certain impact on the environment. However, due to its small radiator volume, it can effectively save space. In addition, liquid cooling can also reduce the impact of noise on the environment by optimizing the design and layout of the radiator. 8. Different safety and risk pointsThe safety of air-cooled heat dissipation is relatively high due to its simple structure and no risk of liquid leakage. But it is necessary to pay attention to the safety issues of the fan to prevent damage or overheating.The safety of liquid cooling is relatively low, and there are risks such as liquid leakage and corrosion. Therefore, the liquid cooling cooling system needs to use high-quality materials and strict sealing design to ensure safe operation. ConclusionAir cooling and liquid cooling are two commonly used heat dissipation methods in energy storage systems, each with its own advantages and disadvantages. When choosing a cooling method, it is necessary to comprehensively consider factors such as the actual power of the equipment, cooling requirements, and cost budget. With the development of technology, more efficient and low-cost new heat dissipation methods (such as the combination of air cooling and liquid cooling, immersion, etc.) may emerge in the future to provide guarantees for the stable operation of energy storage systems.
