AI Technical Summary

Technical Problem

Existing technologies for monitoring thermal runaway in vehicle batteries suffer from several drawbacks. Thermal runaway warnings are easily delayed or lost, and high-priority alarms cannot be delivered in real time with low latency and high reliability. In particular, it is difficult to maintain the continuity and temporal consistency of thermal data under conditions of unstable communication or limited edge node resources.

Method used

A multimodal monitoring method for thermal runaway of vehicle batteries based on edge PCDN is adopted. By collecting thermal imaging data, communication link data and cross-node alarm transmission data, a standardized vehicle status dataset is constructed to conduct risk assessment and reliability analysis, adjust the data transmission mode in real time, generate collaborative assessment results and trigger corresponding alarm levels.

Benefits of technology

Under conditions of unstable links or limited node resources, maintaining the continuity and structural consistency of monitoring data improves the timeliness of anomaly identification, enabling timely identification of changes in local high-temperature areas and enhancing the response capability during the thermal runaway surge phase.

Abstract

The invention discloses a vehicle-mounted battery thermal runaway multi-mode monitoring method and system based on edge PCDN, and relates to the technical field of intelligent traffic battery monitoring. The vehicle-mounted battery thermal runaway multi-mode monitoring method and system based on the edge PCDN comprises the steps that S1, thermal imaging data, communication link data and cross-node alarm transmission data in the vehicle monitoring process are collected and preprocessed, and a standardized vehicle state data set is constructed; s2, performing risk assessment on the thermal evolution state of the vehicle battery, and triggering a corresponding alarm level; s3, analyzing the overall transmission environment, and adjusting the data transmission mode in real time; and S4, carrying out collaborative evaluation on the operation state of the alarm link, and generating a regulation and control instruction of cache allocation. The problems that in a weak network family parking environment, due to the fact that a parking space distributed architecture and a link are unstable, alarms are prone to being delayed or lost, and low-time-delay and high-reliability real-time delivery of thermal runaway type high-priority alarms cannot be achieved in the prior art are solved.
