Battery packs do not specifically refer to lithium battery packs, but include various types of battery packs such as lead-acid battery packs, nickel hydrogen battery packs, and lithium battery packs.
Definition and classification of battery packs
A battery pack is a battery assembled from a set of individual cells, typically used for energy storage or providing high power output. There are many types of battery packs, mainly including the following:
Lead acid battery pack: mainly used in the fields of automobiles, UPS power supply, etc. Its advantage is low cost, but its disadvantages are low capacity density, poor safety, and short lifespan.
Nickel hydrogen battery pack: mainly used in electric vehicles, energy storage power stations and other fields. Its advantages are high capacity density, high charging efficiency, and environmental protection. Its disadvantages are higher price and shorter lifespan compared to lithium battery packs.
Lithium battery pack: widely used in fields such as mobile power banks, laptops, electric vehicles, and energy storage stations. Its advantages include high energy density, long lifespan, and high charging efficiency. However, its disadvantages include high price and special attention to safety.
Composition and function of battery pack
A battery pack is a battery system composed of a certain number of cells arranged in a designed series and parallel structure. By connecting multiple battery cells in series, the voltage of each cell is accumulated to achieve an output voltage based on the corresponding multiple of the cell voltage; By parallel connection of battery cells, the capacity of multiple cells is accumulated to provide electrical energy capacity based on the corresponding multiple of cell capacity. The design and structure of battery packs can be customized according to different spatial structures and application scenarios.
