Photovoltaic energy storage:

High-Temperature Stability Testing for Lithium-Ion Battery Packs.

Application: A energy storage company required validation of lithium-ion battery performance under extreme conditions.

Testing Protocol:
Temp Cycling: -20°C to +70°C (10 cycles) to simulate day-night fluctuations.
Humidity Control: 30–90% RH to mimic arid environments.
Cycle Life Assessment: 2,000+ charge-discharge cycles under thermal stress.

Key Results:
Capacity Retention: 92% after 2,000 cycles at +50°C.
Safety : No thermal runaway events detected via built-in thermal imaging.
Benefit: Extended warranty period from 1 to 3 years for long-term deployments.

New Energy Vehicles:
