Project Background

A JD-level smart logistics park in the Yangtze River Delta covers an area of 500,000 square meters, with the deployment of over 200 AGVs and a centralized lithium battery charging area. In 2024, two AGV lithium battery thermal runaway and fire accidents occurred in other logistics parks in the same industry, which attracted great attention from customers. The customer’s requirement is to provide an early warning five minutes before thermal runaway develops into a fire.

Customer Pain Points

  • The diffusion of precursor gases (H₂ + CO + electrolyte VOC) from AGV lithium battery thermal runaway is rapid, whereas traditional smoke detectors respond slowly
  • The charging area is spacious and AGVs move frequently, necessitating careful placement of fixed monitoring points
  • The power coverage in the warehouse is poor, and wireless LoRa transmission is required for some points.
  • Integration with WMS (Warehouse Management System) is required, with automatic locking of storage locations upon exceeding limits + notification to duty personnel

URION Solutions

  • Core Monitoring in Charging Area: 80 sets of points, with 4 sets per charging pile cluster (H₂ + CO + VOC + Temperature)
  • Three-gas composite monitoring: Insight into YQGT-H2 + YQGT-CO + Pioneer YQZW PID (VOC), covering the entire stage of thermal runaway
  • Wireless LoRa deployment: Avoids the impact of power cables on warehouse operations
  • Key Points of AGV Corridor: Deploy smoke + CO monitoring at the intersection of the AGV corridor
  • WMS Integration: automatic locking of storage locations upon exceeding limits + notification to duty personnel
  • AI Early Warning: Based on the combined curve of H₂ and VOC, provides early warning of thermal runaway 5-15 minutes in advance

Implementation Effect

  • The system has been in trial operation for 6 months, successfully warning of an AGV lithium battery anomaly (alerted 7 minutes before thermal runaway)
  • WMS automatically locks relevant storage locations to prevent interference with over 30 AGVs
  • The fire department has approved the inspection, and the logistics park has been awarded the title of ESG Safety Management Demonstration Unit
  • 4G + LoRa dual-link, with an annual availability rate of 99.95%
