Abstract
Based on the current safety relationship of new energy vehicle batteries, this paper proposes a battery supervision system based on NB-IoT cloud. In this paper, the current state of battery charge in the pool is estimated by establishing a parametric model combined with the extended Kalman filter algorithm, so as to obtain various safety indicators and nonlinear parameters of the battery of electric vehicles, and real-time monitoring and timely adjustment of the use state and running state of the new energy battery, so as to improve the efficiency of the battery and extend the life of the battery. Aiming at the problem of fault diagnosis and safety regulation during battery use, this paper adopts the combination of multiple evaluation indicators, and realizes the termination and fault adjustment of the operation process by setting parameter threshold and interrupt procedure, so as to ensure the safety and stability of the operation process. In this paper, the upper computer system is designed to complete high-speed interaction and data storage of various parameters of external modules and battery fault diagnosis through NB-IoT cloud, so as to realize accurate supervision of batteries in the new-energy vehicle group.
