Energy storage lithium battery pack: It is a power source that uses lithium batteries as energy storage. It is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium iron phosphate battery packs are more common.
Power lithium battery: Power lithium battery refers to the battery that provides power for transportation. It is generally used in electric vehicles, electric trains, electric bicycles, and golf carts compared to small batteries that provide energy for portable electronic devices. Power battery. The difference between energy storage lithium battery pack and power lithium battery: 1. Different application industries Energy storage lithium battery application industry: power storage power station, mobile communication power supply, new energy storage power supply, aerospace military power supply, solar power generation equipment and wind power generation equipment, etc. The main application range of lithium battery pack: ●Small computer room ●Weak current room and other room sub-systems ●New energy outdoor site; ●Communication base station ●Indoor and outdoor non-air-conditioned sites Power lithium battery application: ●The automobile and motorcycle industries mainly provide electrical energy for the ignition of the engine and the use of on-board electronic equipment; ●Industrial power system, used for power transmission and substation, providing closing current for power unit, providing backup power for public facilities and power for communication; ●In the electric vehicle and electric bicycle industry, instead of gasoline and diesel, there are mainly new energy vehicles, which are used as driving power sources for electric vehicles or electric bicycles. 2. The hardware logic structure of the lithium battery energy storage management system is different Lithium battery pack energy storage management system, the scale of the energy storage system is very large, the hardware generally adopts a two-tier or three-tier model, and the larger scale tends to be a three-tier management system; Power lithium battery management system. The power battery system is in a high-speed electric vehicle. It has higher requirements on the battery's power response speed and power characteristics, SOC estimation accuracy, and the number of state parameter calculations. There is only one layer of centralized or two distributed layers, and there is basically no three-layer situation. Small cars mainly use a layer of centralized battery management system. Two-tier distributed power battery management system. 3. Different types of lithium batteries used Energy storage lithium battery packs mainly use lithium iron phosphate batteries, because lithium iron phosphate batteries are superior to other batteries in terms of safety, environmental protection, size, and weight. More energy storage power stations use lead-acid batteries and lead-carbon batteries. Power lithium battery The current mainstream battery types for electric vehicles are lithium iron phosphate batteries and ternary lithium batteries. There are more possibilities in terms of choice. Security is not very stable either. 4, the capacity and volume requirements are different Energy storage lithium batteries are mainly used for power and require high output power. The lithium battery pack is small in size and light in weight. The energy density of lithium batteries is 3 to 4 times that of lead-acid batteries, 2.5 times that of nickel-cadmium batteries, and 1.8 times that of nickel-hydrogen batteries. Power lithium batteries are mainly used for energy storage, with large capacity requirements, long life requirements, and low self-discharge. The power tool battery has a small capacity and does not need to provide high-power output. 5, the current use range is different Power lithium batteries are generally used in equipment that requires high current discharge (3C-5C), and the damage to the battery is relatively small. Energy storage lithium batteries are used in low current equipment (usually 0.5-1C discharge range). About the difference between energy storage lithium battery pack and power lithium battery, I believe you all understand it. In short, the lithium batteries used in new energy vehicles are all power lithium batteries, and the rest of UPS power supplies, computer rooms, data centers, energy storage power stations, etc. use energy storage lithium batteries. This must be selected according to different industries.
