Type of BMS Classification by structure Centralized BMS All monitoring and control functions are centralized in one node, suitable for small battery packs. Distributed BMS Monitoring and control functions are dispersed across nodes and are better suited for large battery packs, such as electric vehicles. Classification by function Passive balanced BMS mainly through the resistance to consume excess power, suitable…
How BMS works BMS includes control IC, MOS switch, Fuse, NTC thermistor, TVS transient voltage suppressor, capacitor and memory, etc. Its specific form is shown in the figure: BMS can be divided into three protection circuits, designed to ensure the safety and stability of the battery pack under different operating conditions. Primary protection circuit It mainly monitors the basic parameters…
The composition of BMS CSU CSU (Cell Supervision Unit) : that is, cell monitoring unit, lithium-ion batteries are usually composed of many independent cell strings and combined, the number from several to several hundred, not only need to monitor and collect the electrical parameters and status of each cell, but also need to do a good job of balance and…
The function of BMS Perception and measurement Measurement This is the basic function of BMS, including the measurement and calculation of some indicator parameters. There are voltage, current, temperature, electricity, state of charge (SOC), state of health (SOH), state of power (SOP), and state of energy (SOE).SOC can be commonly understood as how much power is left in the battery,…
