A typical Li-ion battery pack is made up of three main parts: the cell, the protection circuit module (PCM), and the battery management system (BMS). The cell is the actual battery itself, and it's responsible for storing and releasing energy. The PCM is a safety feature that protects the cell from overcharging or discharging.
Protection Circuits are crucial components in a BMS, safeguarding Li-ion batteries from potential risks such as overcharge, over-discharge, and short circuits. These protection circuits monitor and prevent overcharging, a condition that can lead to thermal runaway and damage. They may include voltage limiters and disconnect switches.
Next, you need to map out the wiring diagram for your battery pack. This will help you determine how the batteries should be connected and how the wires should be routed. You can find pre-made wiring diagrams for common battery pack
