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.
Three Core Industry Challenges
- Power Grid: High-power charging spikes grid load and widens peak-valley power gap
- O&M Management: Dispersed equipment, inconsistent communication protocols and high manual inspection costs
- 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.
