The Battery Management System is a hardware component with an on-board electronic system that manages a rechargeable battery (either a single cell or a pack). It serves as the connection between the battery and its user. Our BMS incorporates a control module, a display module, a wireless communication module, and an acquisition module for documenting the battery's history.

There are several drawbacks to rechargeable batteries, including a low power storage rate, short life cycles, series or parallel circuits, safety concerns, difficulties in estimating battery power, and so on. Moreover, the characteristics of different batteries vary significantly. The BMS system, commonly referred to as the Battery Manager, can manage and maintain each cell more intelligently, enhance battery utilization, prevent overcharging and discharging of the battery, extend battery life, and monitor the battery's status.
