Chen Mingxiang, Chief Engineer of EAST Charging Pile Product Line: Technical Innovation & Large-scale Application of All-scenario Intelligent O&M for Integrated PV-ESS-Charging System
June 2, 2026
 

Event Overview

 
The 5th China International PV-ESS-Charging Industry Conference (BRICS PV-ESS-Charging Forum) was held in Shanghai on May 14, centering on technological innovation and commercialization of integrated PV-ESS-charging solutions. Chen Mingxiang delivered a keynote speech titled Technical Innovation & Large-scale Application of All-scenario Intelligent O&M for Integrated PV-ESS-Charging System.
 
 
 

Corporate Profile

 
Founded 37 years ago, EAST (Stock Code: 300376) has evolved from a leading UPS manufacturer into an ecological enterprise focusing on new energy and energy storage.
 
Its wholly-owned subsidiary ZNEE has been certified as a national-level "Little Giant" specialized & sophisticated enterprise.
 
EAST runs 268 service outlets worldwide, with over 50,000 DC charging piles in operation, completing more than 50 million charging sessions across over 100 countries.
 
 

Three Core Industry Challenges

 
  1. Power Grid: High-power charging spikes grid load and widens peak-valley power gap
  2. O&M Management: Dispersed equipment, inconsistent communication protocols and high manual inspection costs
  3. Application Scenarios: Diversified technical requirements for passenger EVs, heavy-duty trucks, highway stations and mining yards

 

 

Core R&D Breakthroughs (Hardware + Intelligent Software)

 

1. High-standard Hardware Portfolio

 
  • World-first 1072kW semi-submerged liquid-cooled ultra-fast charger: 10+ year service life, module failure rate below 0.1%, 45dB low noise, IP65 & C5 corrosion protection, cost comparable to air-cooled products
  • 400kW/480kW dedicated heavy-duty truck chargers: max 300A per gun, stable operation at -40℃~60℃
  • 720kW–1440kW full liquid-cooled highway ultra-chargers with 1200A liquid-cooled connector: 90% SOC replenishment for 300kWh battery within 15 mins
  • Self-developed 60kW low-noise charging module (55dBA)

 

 

2. AI-powered Predictive O&M Software

 
  • Real-time monitoring of over 200 parameters with Class 0.5 precision; 92%+ fault prediction accuracy, early warning up to 72 hours in advance
  • 100% automatic fault identification and over 90% remote auto-repair; O&M efficiency up 40%–50% and staffing cut by 60%
  • EMS intelligent energy management: power consumption reduced by over 25%; cell temperature difference controlled within 3℃ with three-tier fire protection linkage

 

 

3. Full-coverage Intelligent O&M System

 
  • Edge-cloud collaboration: local data pre-processing via smart gateway to cut bandwidth cost and latency
  • Automated inspection by robots & UAVs lifting patrol efficiency by 80%
  • Multi-network redundancy & hotspot data transmission to ensure connectivity of remote off-grid stations

 

 

Commercial Application Results

 
  • Highway charging hubs: peak grid load -30%, charging efficiency +50%, O&M cost -40%, renewable energy consumption ≥85%
  • Heavy-duty truck & logistics parks: no large-scale grid upgrading required, annual revenue +20%+, equipment failure rate -70%
  • Urban public charging stations: O&M headcount -60%, fault response within 15 mins, station utilization +35%

 

 

Core Viewpoint

 
The industry shall shift from volume-driven expansion to quality-oriented development and avoid vicious hardware price competition. EAST aims to build globally competitive edges via superior intelligent O&M and product quality.
