BMS detailed explanation

Battery BMS management system, also known as battery management system, is a device or system used to monitor and manage batteries. It is commonly used on lithium battery, nickel-metal hydride and other types of rechargeable batteries to ensure their safety, performance and longevity.

Its main functions include:
Battery monitoring: BMS monitors key parameters such as battery voltage, current, and temperature to understand the working status of the battery in real time.
Condition assessment: Calculates the battery’s state of charge (SOC), state of health (SOH) and remaining life.
Balanced management: Ensure that each battery unit in the battery pack can be charged and discharged evenly, extending the service life of the entire battery pack.
Charge and discharge protection: BMS can monitor and control the charge and discharge process of the battery to avoid overcharge, over-discharge, over-current, etc., thereby ensuring the safe operation of the battery.
Temperature management: BMS monitors the temperature of the battery and takes measures when necessary to prevent the battery from overheating, thereby reducing safety risks and increasing battery life.
Communication and data recording: BMS usually has a communication interface that can communicate with other systems and record the battery’s operating data in order to analyze and optimize the battery’s performance.

BMS can monitor the voltage of the battery in real time and transmit the data to external devices through the communication interface for further analysis and processing.
Voltage sensor: A voltage sensor is a sensor device specifically designed to measure voltage, usually with high accuracy and fast response. A voltage sensor can be installed on the positive and negative terminals of the battery, and the real-time voltage information of the battery can be obtained through the voltage value output by the sensor.
Generally speaking, the voltage acquisition frequency of common battery BMS is between tens of Hz and hundreds of Hz, and the accuracy is usually between a few mV and tens of mV. This range can meet the needs of most application scenarios, but the specific collection frequency and accuracy need to be determined based on specific project requirements.

In general, the battery management system is a key technology that can ensure that the battery operates under safe, efficient and reliable conditions, and affects the performance and life of the battery system to a certain extent.
