A wireless battery management system and method for electric vehicles based on nb-iot technology

Abstract

The invention discloses an electric vehicle battery wireless management system and method based on NB-IOT technology. The system includes a user terminal, a vehicle battery terminal and a monitoring center. The battery of the electric vehicle has a unique electronic label, and the on-board battery terminal records the electric vehicle battery power, capacity, geographical location, charge and discharge times and other information in real time, and transmits the NB‑IOT signal to the monitoring center through the NB‑IOT cellular base station, which is convenient The monitoring center intelligently manages the electric vehicle battery; the user terminal obtains the real-time information of the battery through information interaction with the monitoring center, and at the same time communicates with the battery through wireless communication, which facilitates the user terminal to manage the authority of the battery; the present invention uses NB-IOT cellular Internet of Things technology , which realizes real-time information collection and remote monitoring of electric vehicle battery information, which is beneficial to solve problems such as the scheduling of mobile rechargeable batteries; realizes mobile viewing of electric vehicle battery real-time information by user terminals, and simplifies the battery authorization process.

Description

technical field [0001] The invention belongs to the field of information technology, and in particular relates to an electric vehicle battery wireless management system and method based on NB-IOT technology. Background technique [0002] With the deepening of the global energy crisis and the continuous improvement of new energy power technology, the use of pure electric vehicles has gradually become the development trend of the automotive industry. At present, most electric vehicle batteries on the market are fixed in the vehicle and cannot be directly replaced, and lack a monitoring system for the real-time operating status of the battery, which greatly limits the service life of electric vehicle batteries, causing unnecessary economic losses and safety. Hidden dangers also restrict the promotion and development of electric vehicles. [0003] With the development of automobile manufacturing technology and battery technology, mobile replaceable electric vehicle batteries ha...
