The difference between lithium battery protection board and lithium battery management system

The difference between lithium battery protection board and lithium battery management system, starting from the introduction of the two:
BMS Battery Management System: The Battery Management System is composed of the first letter, which means the battery management system. It is used to manage the system of the entire battery group, collect all signals of the battery, such as voltage, current, temperature, etc., and distinguish these signals into overvoltage, low voltage, discharge overcurrent, charging overcurrent, high temperature charging and discharging, low temperature charging and discharging, short circuit, etc. These signals are stored or analyzed for use in terminal products. BMS, in a broad sense, is often considered a protective board, while in a narrow sense, it is a system for battery management.
PCM Battery Protection Board: The Protection Circuit Module is composed of the first letter, which means the protection circuit module. It is used to manage the circuit of the battery module, commonly known as the battery protection board. Some of the protection boards can meet the requirements of BMS, collect all signals of the battery, such as voltage, current, temperature, etc., and distinguish these signals into overvoltage, low voltage, discharge overcurrent, charging overcurrent, high-temperature charging and discharging, low-temperature charging and discharging, short circuit, etc. Although these functions do not exist simultaneously, they can also operate independently. Some protection boards only have monitoring functions, and these types of protection boards are usually used in conjunction with MCUs. MCU is a Micro Controller Unit composed of the first letter, also known as a Single Chip Microcomputer. It refers to the integration of the CPU, RAM, ROM, timer, and various I/O interfaces of the calculator on a single chip with the emergence and development of large-scale integrated circuits. Different functions can be assigned to the MCU through software programming.
