What is the difference between an energy storage lithium-ion battery pack and a power lithium-ion battery?

①The battery capacity difference is in the environment of new batteries. Use a discharge meter to test the battery capacity. Generally, the capacity of power lithium-ion batteries is about 1000-1500mAh; the capacity of energy storage lithium-ion battery packs is above 2000mAh, and some can reach 3400mAh. . ②Application industry difference. Power lithium-ion battery is used for electric vehicles, electric bicycles, electric motorcycles, electric equipment and object driving power batteries; used for power transmission and substations, supplying closing current for power units; important applications of energy storage lithium-ion battery packs It is used in energy storage power stations such as water power, thermal power, wind power and solar power stations, peak and frequency modulation power assistance, digital products, power products, medical and security, and UPS power supplies. ③Battery management system BMS position difference In the energy storage system, the energy storage lithium-ion battery only interacts with the energy storage converter at high voltage, and the converter takes electricity from the exchange grid to charge the battery pack; the battery pack may change The power is supplied by the converter, and the electric energy is converted into exchange through the converter and sent to the exchange grid; the BMS of the electric vehicle, at high voltage, has an energy exchange relationship with the electric idea and the charger; in terms of communication, it is in the charging process with the charger There is information interaction, in all application processes, there is the most detailed information interaction with the vehicle controller. ④Different types of recycled batteries. Energy storage lithium-ion batteries. Energy storage power stations. For safety and economic considerations, when choosing lithium-ion battery packs, they often choose lithium iron phosphate batteries. More and more energy storage power stations use lead-acid batteries. , Lead-carbon battery; power lithium-ion battery The current mainstream battery examples for electric vehicles are iron phosphate lithium-ion batteries and ternary lithium-ion batteries. ⑤The performance and design are not communicated. Power lithium-ion batteries are more focused on charging and discharging power, etc., requiring fast charging rate, high output power, and vibration resistance, especially emphasizing higher safety and high energy density in order to achieve long-lasting battery life. Lightweight requirements in terms of weight and volume; the preparation of energy storage lithium-ion batteries emphasizes battery capacity, especially requirements for operational stability and service life, and consider the consistency of battery modules. In terms of battery materials, attention should be paid to expansion rate, energy density, and electrode materials. To pursue the long life and low cost of the overall energy storage equipment. ⑥Property difference Power lithium-ion battery refers to the battery that supplies power for transportation objects, generally related to the small battery that supplies energy for portable electronic equipment; ordinary energy storage lithium-ion battery is a kind of lithium metal or lithium alloy. The negative electrode material, a primary battery that uses a non-aqueous electrolyte solution, does not communicate with the rechargeable lithium-ion battery and the lithium-ion polymer battery.
