Briefly describe the meaning and use of lithium battery protection board and battery management system

The lithium battery maintenance board also has a balanced maintenance effect, and there are two methods of energy consumption and energy conversion. Energy-consumption equalization refers to the use of resistors to consume a certain battery with high power or voltage among multiple strings of batteries. Energy-consuming balance is divided into equalization during charging, voltage fixed-point equalization, and static automatic equalization. Balance during charging: When charging, when the voltage of any battery is higher than the average voltage, the maintenance board will start the balance maintenance. Voltage fixed-point equalization: The lithium battery maintenance board is fixed at a voltage point to start the equalization, which is only performed at the end of the battery charging, and the equalization time is short. Static automatic balance: During charging or discharging, even if the battery is in a static state, when the voltage is inconsistent, the lithium battery maintenance board will initiate balance maintenance until the voltage remains consistent. The transfer type is to transfer a large-capacity battery to a small-capacity battery by means of energy storage, and balance the capacity of the test battery, which is divided into constant capacity balance and fixed-point capacity balance. Battery Management System Battery Management System (Battery Management System) is abbreviated as BMS, which has the function of measuring battery voltage, and also contains battery maintenance functions, battery balancing functions, battery storage functions, energy measurement functions, network communication functions, etc. The battery management system can guard against abnormal conditions such as over-discharge, over-charge, and over-temperature of the battery. Since lithium batteries may damage battery functions and even explode in severe overcharge and overdischarge conditions, the battery management system exists to monitor, maintain, and manage lithium batteries in a balanced manner, and then improve the work efficiency of lithium batteries. The similarities and differences between the lithium battery maintenance board and the battery management system BMS The lithium battery maintenance board and the battery management system both have a maintenance effect on the lithium battery. The differences between them are: 1. The lithium battery maintenance board is composed of IC, MOS tube, resistor and capacitor components, and is an important component of the lithium battery. The battery management system can be edited and comes with battery management software, which is relatively smarter, equivalent to the brain of a lithium battery, and has a control effect. 2. The lithium battery maintenance board has an important effect in the field of 3C lithium battery and power lithium-ion battery, and the battery management system is used in the field of power lithium-ion battery.
