Lithium-storage battery pack: It is a lithium-ion battery for energy storage. It is a primary battery that uses lithium metal or lithium alloy as a negative electrode material. It uses a non-aqueous electrolyte solution.
Power lithium battery: Power lithium battery refers to the battery that powers transportation vehicles. It is generally used in electric vehicles, electric trains, electric bicycles, golf carts, etc., compared to small batteries that provide energy for portable electronic equipment. Powered battery.
The difference between energy storage lithium battery pack and power lithium battery:
1, the application industry is different
Energy storage lithium battery application industry: power storage power station, mobile communication power, new energy storage power, aerospace military power, solar power equipment and wind power equipment.
Lithium battery pack main application range:
●Small computer room ●Weak room and other room division system ●New energy outdoor site;
●Communication base station ● Indoor and outdoor airless stations ● Radio and television, troops, oil and meteorological sites.
Power lithium battery application:
● The automotive and motorcycle industries mainly provide electrical energy for starting ignition of engines and the use of in-vehicle electronic equipment;
●Industrial power system, used for power transmission substation, providing closing current for power units, providing backup power for public facilities and power supply for communication;
●Electric vehicles and electric bicycle industry, replacing gasoline and diesel, mainly new energy vehicles, as the driving power source for electric vehicles or electric bicycles.
2, lithium battery energy storage management system hardware logic structure is different
Lithium battery pack energy storage management system, the energy storage system is very large, the hardware generally adopts two-layer or three-layer mode, and the larger scale tends to the three-tier management system;
Power lithium battery management system, the power battery system is on the high-speed electric vehicle. It has higher requirements on the battery's power response speed and power characteristics, SOC estimation accuracy, and state parameter calculation quantity. Only one layer is centralized or two. Distributed, basically no three-tier situation. Small car mainly uses a layer of centralized battery management system. Two-layer distributed power battery management system.
3, the type of lithium battery used is different
The lithium storage battery pack mainly uses lithium iron phosphate batteries, because lithium iron phosphate batteries are superior to other batteries in terms of safety, environmental protection, volume, weight, etc. More energy storage power stations use lead-acid batteries, lead. Carbon battery.
The current mainstream battery types for power lithium battery electric vehicles are lithium iron phosphate batteries and ternary lithium batteries. There are many possibilities for selection. The safety aspect is not very stable.
4, different volume and volume requirements
The energy storage lithium battery is mainly for power supply, and it is required to output high power. The lithium battery pack is small in size and light in weight. The energy density of the lithium battery is 3 to 4 times that of the lead-acid battery, 2.5 times that of the nickel-cadmium battery, and is nickel. Hydrogen battery 1.8 times.
Power lithium batteries are mainly used for energy storage, 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 range is different
Power lithium batteries are generally used on equipment that requires high current discharge (3C-5C), but the battery damage is relatively small, and the energy storage lithium battery is used in small current equipment (usually 0.5-1C discharge range).
Regarding the difference between the energy storage lithium battery pack and the power lithium battery, I believe you all understand it. In short, the lithium battery for the new energy vehicle is the power lithium battery, the rest of the UPS power supply, the computer room, the data center, the energy storage power station. The energy storage lithium battery is used, this is to be selected according to different industries.
