Description
TECHNICAL FIELD

[0002] In modern electronic devices and energy storage systems, battery packs serve as the core energy supply unit, and their design and functionality directly impact the operational efficiency and performance of the devices. However, traditional battery pack designs often only provide a single voltage output, which is insufficient when facing devices that require different voltage levels.
[0003] Battery pack design primarily revolves around single voltage output, which simplifies the complexity of the battery management system (BMS) and reduces manufacturing costs. However, as electronic devices become more diverse and complex, single voltage output battery packs cannot meet the needs of all devices. For example, some low-power devices may require lower voltage levels, while high-power devices require higher voltage to drive their high-performance components. This diversity of needs requires battery packs to provide flexible voltage output to adapt to different working conditions.
[0004] In traditional battery pack designs, battery cells are typically connected in series or parallel to form the required total voltage and capacity. However, this configuration limits the voltage output range, allowing only one fixed voltage level to be provided. This means that if a device requires a different voltage level, the user must carry multiple battery packs or use external voltage conversion equipment, which not only increases cost but also increases system complexity and weight.
