UAV battery management system (BMS) is the core component of UAV power system. It is mainly responsible for monitoring, protecting and managing the battery to ensure the safety and stable performance of the battery. This article will introduce the constituent elements of UAV battery management system and the functions and functions of each component.

I. Basic constituent elements of BMS

1. Battery Management chip (Battery Management IC): It is the core component of BMS, responsible for monitoring the Battery voltage, temperature, current and other parameters, and mastering the Battery status in real time.
2. Battery Protection Board (Protection Board): it is used to protect the battery from overcharging, overdischarging, short circuit, overcurrent, etc. to prevent battery damage or safety accidents.
3. Temperature Sensor (Temperature Sensor): monitors the Temperature change of the battery to prevent the battery from overheating or catching fire due to excessive Temperature.
4. Battery equalizer (Balancer): it is used to balance the charge and discharge of each single battery in the battery pack to ensure that the battery status in the battery pack is consistent.
5. Communication Interface (Communication Interface): used for data Communication with flight control system or ground station to transmit battery parameters and status information.
6. Power Switch: control battery Power supply Switch, which can realize the charging and discharging operation of the battery.
7. Display Screen (Display Screen): displays the status, power, temperature and other information of the battery, which is convenient for users to monitor and operate. </span>

II. Functions and functions of each component

1. battery Management chip: the battery parameters are monitored and collected in real time through the built-in ADC (analog-to-digital converter) to ensure that the battery is in a safe working state.
2. Battery Protection Board: once the abnormal situation of the battery is detected, such as overcharging and overdischarging, the power supply of the battery will be cut off immediately to protect the safety of the battery.
3. Temperature Sensor: monitor the temperature change of the battery. Once abnormal conditions are found, take timely measures to prevent the battery from overheating and causing accidents.
4. Battery equalizer: by balancing the charge state of each single battery in the battery pack, the battery life is prolonged and the overall performance is improved.
5. Communication Interface: data communication with flight control system or ground station, timely transmission of battery status information, improve flight safety.
6. Power Switch: control battery power supply switch to ensure the safe use and charging of the battery.
7. Display screen: displays the status information of the battery, so that users can understand the usage of the battery, which is convenient for timely adjustment and processing.

Battery Management System of UAV(BMS) is an important component to ensure the safe and stable operation of UAV batteries. Each component plays a different role in the system to ensure the safety and stable performance of the battery. Understanding the constituent elements of UAV battery management system and its functions is helpful for users to better understand and master the working principle of UAV battery management system and improve the flight safety and reliability of UAV.
