Problems solved by technology

However, due to more and more functions of mobile phones, the software and hardware to realize these functions need to consume a large amount of built-in power of mobile phones, especially for display, camera and positioning, which consume a lot of power, which makes the battery life of mobile phones seriously insufficient. , Therefore, many mobile phone users will be equipped with one or more mobile power banks to keep the mobile phone working continuously when they go out
[0003] In the prior art, almost all mobile power supplies sold on the market have a fixed structure, fixed batteries and fixed rated power. Such a design makes the mobile power supply unable to continue to provide electric energy when the power of the mobile power supply is exhausted, thereby Inconvenience to users, especially long-distance travelers
Moreover, mobile power supplies on the market generally use lithium-ion batteries, lithium-ion polymer batteries or 18650 lithium-ion batteries as electric energy storage media. However, the above three batteries have safety hazards such as fire and explosion, making There are potential safety hazards in the storage, transportation and use of mobile power itself
[0004] Batteries are safe, reliable and easy to obtain. Therefore, batteries can also be used to charge mobile phones. However, the connection relationship of batteries in existing battery chargers is fixed and can only be discharged. If the battery is dead, it can only be charged. It is inconvenient to replace the battery or use a battery charger to charge each battery before use
Even if there are some battery chargers that can both discharge and charge, the connection relationship between the batteries is the same when the charger discharges and charges, and the power is fixed and cannot be easily expanded. In this way, if The battery is fixed in series connection, which makes the charging efficiency of the battery very low during charging, and if the battery is fixed in parallel connection, a booster circuit is required during discharge, and the efficiency is not high and it will also generate heat, causing Security risks

Description

technical field [0001] The invention relates to an energy storage device, in particular to a mobile power supply device that can be stacked freely and can both discharge and charge. Background technique [0002] The rapid development of mobile communication technology meets the different needs of users in life and work, especially the most widely used mobile phone, which has a huge impact on people's life and work. Mobile phones not only facilitate the communication between people, but also have multiple functions such as social interaction, entertainment and learning, which makes people's life and work more and more dependent on mobile phones. However, due to more and more functions of mobile phones, the software and hardware to realize these functions need to consume a large amount of built-in power of mobile phones, especially for display, camera and positioning, which consume a lot of power, which makes the battery life of mobile phones seriously insufficient. , Therefo...
