Description

Technical Field

[0001] The utility model relates to the field of battery packs, in particular to a large-volume compact battery pack. Background Art

[0002] A battery pack is a power system composed of multiple batteries connected in series, parallel, or hybrid. These batteries can be of the same or different types, but are generally required to maintain consistency or compatibility in certain parameters to ensure the overall performance and safety of the battery pack. In a series battery pack, the positive and negative electrodes of the batteries are connected in sequence, forming a continuous circuit. The key characteristics of a series battery pack are that the output voltage is equal to the sum of the voltages of each battery, while the output current is the same as that of a single battery. This combination is suitable for applications requiring high voltage.

[0003] Although battery pack designs currently on the market have made significant progress in energy density, safety, and cycle life, they still have limitations in flexibility and scalability. Once assembled, many battery packs have a relatively fixed structure, making it difficult to instantly add, subtract, or reassemble them according to the needs of actual application scenarios. This lack of flexibility not only limits the adaptability of battery packs in changing environments, but also increases the difficulty and cost for users to adjust the energy system under specific circumstances. Therefore, one of the future development directions of battery pack technology will be to explore and develop more modular battery pack structures that are easy to disassemble and reassemble to meet the needs of different fields for highly flexible and customizable energy systems.
