Innovative rapidEIS Technology

Accurately assign battery quality, lifetime, and capacity

Electrochemical Impedance Spectroscopy (EIS) is widely recognized as the most reliable method to evaluate Li-ion battery performance and lifetime. EIS is consistently superior and reliable compared to industry-standard tests like open circuit voltage (OCV), AC resistance at 1kHz (AC-IR), DC pulse methods, and capacity checks.

Key benefits of Safion‘s rapidEIS:

Determine Li-ion battery performance and SOH within seconds
Increase testing throughput and accuracy
Ensure safety and performance of your batteries in the field
