🔋 Battery Degradation in BESS: The Hidden Factor Behind Energy Storage Performance

A Battery Energy Storage System (BESS) does not lose performance overnight — it slowly degrades over thousands of operating hours.

Understanding battery degradation is critical for designing reliable, cost-effective energy storage projects.

❄️ Cold Climate BESS Design: Why DCIR-Based Cutoffs Matter

Extreme cold is one of the biggest hidden challenges for Battery Energy Storage Systems (BESS).

When temperatures drop, lithium-ion batteries experience:

⚠️ Increased internal resistance (DCIR)
⚠️ Higher voltage sag during discharge
⚠️ Reduced available capacity
⚠️ Increased…Read More
