Maintenance Recommendations

⚠️

Cell String 3 Balancing Required

Cell String 3 shows elevated resistance and lower SOH. Recommend performing deep balancing cycle during next maintenance window.

🔄

Capacity Test Due

Quarterly capacity test scheduled for next week. Last test showed 94.5% capacity retention.

📈

Optimize Cycling Pattern

Analysis shows potential to reduce degradation rate by 8% through adjusted DOD limits during low-demand periods.
