Six health dimensions, building a system health landscape.
The generic assessment structure is based on the key health dimensions of the large energy storage systems, which map the state of equipment, historical trends and risk signals into a unified health picture.
Specialized testing equipment and on-site inspection
Battery inaccessibility tester
Measure core / module internal resistance, judge consistency and ageing trends
Insulation electrical resistance tester
Assessment of the insulation level of the current system
Exposure tester
Check connect points, parent rows, key electrical connections
Electrical Quality Analyser
Electricity, current, harmonization, power factor and frequency analysis
Battery resistance analyser
Identification of cell resistance to change and unusual trends
Environmental monitor
Temperature, wind, noise and site environmental inspection
Key Connection and Inner Status Check

Main risks currently identified (example)
| Risk item | Observations | Level |
|---|---|---|
| Battery cluster temperature is high. | Part of the Rack peak temperature difference is 8.7°C. | Very high. |
| Direct current contact with electrical resistance rising. | Trend increase in multiple connections | High |
| Partial connection point temperature rise | Infrared tests have detected local temperature increases. | High |
| Wind efficiency is down. | There's a gap between running currents and flows. | Medium |
| Communication chain fluctuations | Occasionally short-term loss of packages and increased delay | Medium |
Recommendations for a road map for action Example:
Time Range
Key actions
Responsible party
Expected impact
Short term0-30 daysRapid governance and risk reduction
- (a) Reviewing and securing abnormal connections;
- Calibrating temperature measurements and heat management parameters;
- Update key warning thresholds and frequency of inspections.
Transport teamPlant manufacturer / System Integration
- Reduce the probability of a connection failure
- Rapidly improve local temperature differentials
Medium term1–3 monthsImprove performance and eliminate hazards
- Replacement of reduced efficiency wind or pumps;
- Optimizing heat management control strategies;
- Conduct a special inspection of critical insulation and connectivity.
Transport team / equipment supplierMake special arrangements, if necessary.
- Increase heat management homogeneity
- Reduction of unplanned alerts
Long term3-12 monthsEnhancing reliability and longevity
- Undertake assessment of battery lifetime and SOH trends;
- Optimizing cooling system capacity and energy consumption;
- Establish a predictive maintenance baseline and periodic Health Check.
Owner / Transport / Equipment Supply BusinessJoint development of annual plans
- Extension of useful life
- Reducing full-life costs
