AI Technical Summary
Existing multi-battery pack systems lack effective management methods, making it impossible to determine which battery pack(s) will be used for actual discharge or charging, whether newly added battery packs will be used immediately, and how to avoid the problem of high-current mutual charging between battery packs.
By acquiring the battery voltage and usage status of each battery pack, the parallel operation voltage range is determined, target battery packs are selected, and the activation status of the battery packs is adjusted according to their working status and voltage extremes. Priority is given to charging battery packs with low voltage or discharging battery packs with high voltage, thereby reducing the probability of high-current mutual charging.
It enables safe and effective management of multi-battery pack systems, resulting in more balanced voltage, improved charging and discharging efficiency and system safety, and reduced high-current mutual charging phenomena.
