EV Charging Station Electrical-Safety Solution
Harmonic-fingerprint AI analysis, 256 samples/cycle fine sampling, 97.3% arc-recognition accuracy, electrical hazards found 30 days in advance.
Harmonic-fingerprint AI analysis, 256 samples/cycle fine sampling, 97.3% arc-recognition accuracy, electrical hazards found 30 days in advance.
By deploying ESA Full-Factor Smart Meters, ESB three-phase unbalance monitors, EST wireless temperature sensors and FA arc-fault detectors on charging-pile distribution circuits, all charging-circuit parameters are monitored in real time 7x24. The core innovation is harmonic-fingerprint AI analysis: based on 256 samples/cycle fine sampling, deep-learning models recognize harmonic signatures of different charger types, upgrading charging-station safety management from 'passive alarming' to 'proactive prevention'.
Industry Pain Points
No Real-Time Monitoring of Charging-Pile Electrical Parameters
Charging piles generate heavy harmonic pollution; frequent plug/unplug wears connectors, heating terminals and degrading insulation. Conventional protection only reacts passively after faults occur.
Arc Hazards Cannot Be Recognized
Arc faults from loose terminals and worn charging guns are hard to identify with conventional breakers; hazards persist until a fire starts.
Slow Passive Fault Handling
Without real-time monitoring and alarms, fault handling is passive and slow, and electrical-fire risk cannot be controlled in advance.
Difficult Scattered Multi-Site Management
Centralized charging stations, bus depots and charging canopies are scattered without a unified platform for centralized management and remote O&M.
