The Importance Of OCV Curves In Understanding Battery Behaviour

OCV curves are one of the most fundamental components of battery modelling. They capture the true electrochemical behaviour of a cell at rest and form the baseline for accurate SOC estimation, thermal modelling, ageing prediction, and safety analysis.

In this webinar, we break down how OCV curves are measured, what they reveal about battery chemistry, and why they are essential inputs for our hybrid Physics+ML approach. Whether you're designing next-generation EV batteries, calibrating digital twins, or optimising fleet performance, understanding OCV behaviour is critical to achieving high-fidelity simulations and faster model development cycles.

Key Outcomes

By the end of this session, participants will be able to:

1. Understand the OCV–SOC relationship and what makes the curve a unique fingerprint of cell chemistry.
2. Identify key features of OCV curves: plateaus, slopes, hysteresis, and what they reveal about material behaviour.
3. Explain why OCV data is necessary for accurate voltage, thermal, and degradation modelling.
4. Recognise how poor OCV characterisation leads to simulation errors, inefficient calibration, and mispredicted field behaviour.
5. See how oorja’s hybrid physics + ML framework uses OCV curves to deliver chemistry-specific, high-accuracy battery models.
6. Apply OCV understanding to real-world engineering tasks such as fast charging, ageing prediction, cell qualification, and fleet intelligence.
