EV Charging Station Electrical-Safety Solution Solutions

Harmonic-fingerprint AI analysis, 256 samples/cycle fine sampling, 97.3% arc-recognition accuracy, electrical hazards found 30 days in advance.

OVERVIEW

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'.

PAIN POINTS

Industry Pain Points

01
🔌

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.

02
🔥

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.

03
⏱️

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.

04
🗂️

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.
