How EchoStat™ Works

EchoStat™ can screen all common types of battery cells, regardless of size or chemistry. Feasible has systems for pouch, prismatic, and cylindrical cells, which simply slide into the EchoStat™ station.

Ultrasound pulses are sent into one side of the cell and response signals are received on the opposite side, and can cover the full area of a cell. The rapid speed and non-invasive nature of EchoStat™ makes it easy to integrate into any workflow.

Data is examined through EchoStat™’s screening and analytics platform. Feasible’s proprietary software provides deep insights on the differentials within one cell, between multiple cells, and between production lines.

Screening & Analytics Platform

EchoStat™ is supported by Feasible's powerful screening and analytics platform. Easily conduct comparisons of quality across different lines. See a real-time running log of screening data.

Maximum battery performance. Longer-lasting electric vehicles with lower production costs. It all starts with greater assurance from improved quality control at each manufacturing step.
