Entroview SoH solution

Entrodiag allows you to precisely measure the SoH of your battery modules to maximize battery life and reliability.

Why Battery Diagnostics Matter

EV batteries account for up to 40% of the vehicle cost. Without accurate testing, it’s difficult to assess whether a battery is safe and valuable enough for reuse or requires recycling.

Traditional diagnostic methods are obsolete, creating significant uncertainty about battery health.

Entrodiag solves this with a reliable, physics-based diagnostic solution powered by entropy measurements.

The solution: Entrodiag

Entrodiag is your plug-and-play solution, combining the essential hardware and software to accurately diagnose and qualify your EV batteries.

Decision making for every module

At the end of each test, Entrodiag delivers a diagnostic report that goes beyond raw data.

It provides clear, actionable recommendations for every module tested:

Stationary Reuse

Evaluates the battery’s potential for stationary energy storage outside of vehicles.

Vehicle Reuse

Identifies suitable modules for future use in automotive applications.

Recycling

If the module is too damaged or unsafe for reuse.

Your Actionable Report

All diagnostics tests results are consolidated in an easy-to-read report that ensures your decisions are traceable and data-driven.

What our diagnostic solution measures

Entroview’s solution captures key battery health data to help you make informed decisions:

Remaining Battery Capacity

(SOHc - Residual Capacity)

Evaluates how much charge the battery can still hold, guiding whether it’s suitable for reuse or recycling.

Battery Resistance Levels

(Internal Resistance)

Measures resistance across different charge states to assess electrical performance and efficiency.

Degradation modes

(SOHs - Degradation Analysis: LLI & LAM)

Detects critical signs of consumption, like lithium loss and material depletion in electrodes, indicating the battery’s future usability.

“Think of a battery like a dam.”

The energy stored in the battery is like water in a dam. Over time, small cracks (battery degradation) start to form. Entroview detects these “cracks” in real-time, allowing you to act before they lead to major issues, just like fixing a dam before it bursts.
