In August 2026, China’s National Energy Administration issued the 15th Five-Year Action Plan for Power Safety, strengthening safety standards for new energy storage. Safety is no longer a bonus—it is a hard requirement for grid connection and returns.
For EAST, with 30+ years in power electronics, storage safety is an engineering problem that can be broken down, verified, and replicated.
1. Thermal Control: Stop Thermal Runaway at the Source
EAST’s 6.7MWh semi-immersed system uses insulating coolant spray to directly cool core heat points, achieving cluster ΔT ≤2°C and stack ΔT ≤3°C. Centralized liquid cooling keeps cell ΔT within 3°C and cycle life beyond 8,000 cycles—ensuring synchronized cell aging and stable usable capacity.
2. Fire Protection: Three-Level Containment
Immersion liquid absorbs heat and suppresses early thermal runaway.
PACK-level perfluorohexanone spray blocks heat spread.
Active warning and passive suppression form a closed safety loop.
3. System Synergy: Full-Stack Self-Development
EAST develops PACK, PCS, BMS, and EMS in-house with deep AC/DC coupling. Its BMS with ActiveLi enables millisecond cluster balancing and intelligent SOC adaptation, eliminating circulating current, improving battery utilization by 5%, and achieving >99.9% system availability. Four-level protection covers cell–module–cluster–system.
4. Intelligent Diagnosis: An AI Brain for Storage
Based on the eDome platform, EAST provides 7-day advance warning of battery faults and component life prediction—shifting O&M from reactive to proactive. IP66 and C5 anti-corrosion support operation from -40°C to desert heat and sand. Proven from a 1.4GWh plant in Xinjiang to a mining project in Congo.
Safety Is the Foundation of Storage Assets
EAST’s architecture—extreme thermal control, system synergy, AI diagnosis, tiered fire protection, and full-link protection—turns safety into verifiable solutions, quantifiable data, and traceable lifecycle management. With 10GWh of application practice, EAST answers not “whether safety matters,” but “how safety should be done.”
