The battery protection circuit board, commonly known as the PCB, is the battery management system usually for small batteries. They typically are used for digital batteries. To understand PCBs well, you need to know about battery management systems or BMS.
Battery protection packs can be divided into two categories. The first category is the Protection Circuit Module (PCM) it is also known as Protection Circuit Board or (PCB), And the other type is the Battery Management System (BMS). In the lithium battery, the battery management system is an essential part of it.
Key Functions of a Battery Management System: Battery Monitoring: The BMS continuously monitors the voltage and current of each individual battery cell or module within the pack. It keeps track of the overall state of charge and determines the remaining capacity of the battery.
A typical BMS consists of various components, including voltage and current sensors, temperature sensors, control circuitry, and communication interfaces. These components work together to ensure the safe and efficient operation of the battery pack.
Battery packs, especially the big ones, have power batteries that protect the battery packs from overcharging, discharging, over current, cell balancing functions, and short circuits during battery charging. Some of these batteries need to communicate data with input and output options.
The BMS should incorporate a cell balancing circuitry that redistributes charge between cells as needed to maintain balance. This can be achieved using techniques such as active or passive cell balancing. Temperature is another critical parameter to monitor in a battery pack.
The BMS can activate a balancing circuit that diverts excess charge from higher voltage cells or modules to lower voltage ones, maintaining a balanced state across the battery pack. Communication and Control: The BMS facilitates …
