What are the differences between battery protection board and battery management system

BMS battery management system: BatteryManagementSystem is composed of the previous letter, which means battery management system, a system used to manage the entire battery, and then collect all the signals of the battery, such as voltage, current, temperature, etc., and divide these signals into Overvoltage, low voltage, discharge overcurrent, charge overcurrent, high temperature charge and discharge, low temperature charge and discharge, short circuit, etc., store or decompose these signals for use in end products. BMS is often regarded as a protection board in a broad sense, and a battery management system in a narrow sense. Battery protection board PCM battery protection board: ProtectionCircuitModule is composed of the previous letter, which means protection circuit module, used to manage the circuit of the battery module, commonly known as battery protection board, part of the protection board function can meet the requirements of BMS, and can collect batteries All signals, such as voltage, current, temperature, etc., and divide these signals into overvoltage, low voltage, discharge overcurrent, charge overcurrent, high temperature charge and discharge, low temperature charge and discharge, short circuit, etc., although these functions are not at the same time Both exist, but they can also operate independently. Some protection boards only have monitoring functions, and this type of protection boards are usually used with MCUs. MCU is composed of MicroControllerUnit and the previous letter, also known as SingleChipMicrocomputer (SingleChipMicrocomputer), abbreviated as single chip, which means that with the emergence and development of large-scale integrated circuits, the calculator's CPU, RAM, ROM, The MCU and multiple I/O interfaces are integrated on a single chip, and the MCU can be given different functions through software layout.
