The invention relates to the technical field of battery management in communication energy storage products, and in particular relates to a battery management system based on Internet of Things. Battery pack voltage is converted into working voltage of a main control unit through a DCDC converter, a temperature detection unit, a current detection unit and a voltage detection unit are respectively used for monitoring a temperature value, a current value and a voltage value of the battery pack in real time and sending the values to the main control unit through a CAN bus interface, the temperature value, the current value and the voltage value are stored to a data storage device through the main control unit, an Internet of Things terminal connected with the main control unit is used for receiving a command issued by equipment at the Internet of Things terminal and controlling a fan, a voltage balance circuit and a battery protective circuit so as to regulate the temperature of the battery pack, balance the voltage of a simple battery and protect over-charging, over-discharging, over-current, over-temperature and short-circuit. Through the communication of the Internets of Things terminal and the equipment at the Internet of Things terminal, the running parameter of the battery pack can be uploaded and managed in real time.
Description
technical field [0001] The invention relates to the technical field of battery management of communication energy storage products, in particular to a battery management system based on the Internet of Things. Background technique [0002] With the continuous development of communication technology, the application of communication energy storage products has been widely promoted, and most communication energy storage products use lithium-ion battery packs. Protection, over-temperature protection, short-circuit protection and other extreme conditions are easy to shorten and damage the lifespan. Therefore, a battery management system based on the Internet of Things that is used for real-time monitoring and management of the battery pack has emerged as the times require, and involves Internet data centers and communication base stations. In the battery management system based on the Internet of Things using 240V high-voltage direct current, most of the current methods are to d...
