Project Scope of Chen Tech
1. Development of Low-Risk Retired Battery Management Technology
-
Pre-input Verification Mechanism for Retired Batteries: Designed a verification mechanism covering traceability, visual inspection, and protection function checks to ensure baseline safety.
-
Cell & Core-Pack Level Pre-input Inspection: Fast SOH (State of Health) estimation for cells and core packs prior to deployment, with an error margin of <±8%.
-
Module-Level Online SOH Monitoring: Continuous online SOH monitoring at the module level, with an error margin of <±3%.
-
In-Use Risk Feature Detection & Rapid Screening for Retired Batteries: * Achieved a >90% accuracy rate for the rapid detection of “balancing cycle activation” and “balancing failure.”
-
Implemented multi-level warning systems based on dynamic detection of:
-
Bottleneck cell features (probability of minV_ID ≧70%)
-
Work-and-rest behavioral features (standardized deviations: LVS, HVS)
-
Temperature profile features (temperature variance ≦5℃).
-
-
2. Development of High-Efficiency Intelligent Microgrid Control System
-
Asynchronous Adaptive Charge/Discharge Algorithm among Battery Packs: Enables asynchronous operations between battery packs with a response and decision-making time of 0.9 seconds.
-
In-Operation Battery Decommissioning Mechanism: Allows dynamic decommissioning of battery packs during operation, with a battery branch power redistribution response time of 0.292 seconds.
-
Performance Verification of Low-Carbon, Full-Green-Energy Microgrid: Achieved a conversion efficiency of 93.3% under direct green energy supply.
3. Full-Green-Energy Microgrid Integration and Field Validation
