Wireless management system and method based on NB-IOT (Narrow Band Internet of Things) technology for electric vehicle battery

Abstract

The invention discloses a wireless management system and method based on an NB-IOT (Narrow Band Internet of Things) technology for an electric vehicle battery. The system comprises a user terminal, avehicle-mounted battery terminal and a monitoring center. The electric vehicle battery is provided with a unique electronic label; the vehicle-mounted battery terminal records information such as theelectric quantity, the capacity, the geographical position and the charging and discharging times of the electric vehicle battery in real time, and transmits the information to the monitoring center through an NB-IOT cellular base station, so that the monitoring center performs intelligent management on the electric vehicle battery; and the user terminal acquires real-time information of the battery through information interaction with the monitoring center, and communicates with the battery through wireless communication, so that the user terminal can perform permission management on the battery conveniently. The NB-IOT technology is used, so that real-time information acquisition and remote monitoring of the information of the electric vehicle battery are realized, the problems concernedwith scheduling of a mobile charging battery and the like are solved; the real-time information of the electric vehicle battery can be checked in a mobile way by the user terminal; and a battery authorization use flow is simplified.

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...
