What is the difference between energy storage lithium battery pack and power lithium battery?

①The battery capacity is different. In the case of new batteries, use a discharge meter to test the battery capacity. Generally, the capacity of power lithium batteries is about 1000-1500mAh; the capacity of energy storage lithium battery packs is above 2000mAh, and some can reach 3400mAh. ②Different power lithium batteries in the application industry are used as batteries for driving power supplies for electric vehicles, electric bicycles, electric motorcycles, electric equipment and tools; used in power transmission and substations and supplying closing current for power units; energy storage lithium battery packs are mainly used in water power , Thermal power, wind power and solar power stations and other energy storage power stations, peak and frequency modulation power auxiliary services, digital products, power products, medical and security, and UPS power supplies. ③The location of the battery management system BMS is different. In the energy storage system, the energy storage lithium battery only interacts with the energy storage converter at high voltage, and the converter draws electricity from the AC grid to charge the battery pack; or the battery pack converts the current The electric energy is converted into AC through the converter and sent to the AC grid; the BMS of electric vehicles has an energy exchange relationship with the electric motor and the charger at high voltage; in terms of communication, there is information with the charger during the charging process. Interaction, in the entire application process, there is the most detailed information interaction with the vehicle controller. ④Different types of batteries are used. Energy storage lithium battery energy storage power station. For safety and economic considerations, when choosing lithium battery packs, lithium iron phosphate batteries are often used, and some energy storage power stations use lead-acid batteries, lead carbon Battery; power lithium battery The current mainstream battery types for electric vehicles are lithium iron phosphate batteries and ternary lithium batteries. ⑤Different performance and design. Power lithium batteries focus more on charging and discharging power and other aspects, requiring fast charging rate, high output power, and vibration resistance, especially emphasizing higher safety and high energy density to achieve long-lasting battery life, and weight Lightweight requirements in terms of volume; the preparation of energy storage lithium batteries emphasizes battery capacity, especially requirements for operational stability and service life, and more consideration is given to the consistency of battery modules. In terms of battery materials, attention should be paid to the expansion rate and energy density, and the uniformity of electrode material performance. In order to pursue the long life and low cost of the overall energy storage equipment. ⑥Different power lithium batteries refer to batteries that supply power for transportation, generally related to small batteries that supply energy for portable electronic devices; ordinary energy storage lithium batteries are a kind of lithium metal or lithium alloy as the negative electrode material , The use of non-aqueous electrolyte solutions for primary batteries is different from rechargeable batteries, lithium batteries and lithium ion polymer batteries.
