Description

Technical field

[0001] The invention relates to a device for charging and maintaining a battery pack and detecting the charging and discharging characteristics of the battery. It can charge the battery pack in series and at the same time adjust the terminal voltage of each single battery in the battery pack in series to be consistent, and can automatically adjust the battery pack in series. The charging and discharging characteristics of each single battery in the battery pack are detected and analyzed, and the user is prompted to replace the single battery whose charging and discharging characteristics are seriously degraded or invalid. Battery packs suitable for handheld or mobile devices, especially suitable for high-power, large-capacity power battery packs, and belong to the electrical control category. Background technique

[0002] The currently known method of charging a battery pack connected in series is to charge the connected battery pack as a whole. During the ch...
