ARTIPhy

Physics-based battery insight from real-world data

Artiphy infers model parameters, internal states and degradation behaviour from ordinary current, voltage and temperature measurements.

Machine-learning-accelerated surrogate models deliver orders-of-magnitude speedups over classical electrochemical solvers, enabling inference workflows that were previously impractical.

Battery modelling sits at the heart of modern electrification. Physics-based models can describe the internal electrochemistry of a cell and predict performance, degradation and safety across operating conditions.

But in practice, these models are often too slow, difficult to parameterise and hard to keep accurate as cells age or move into real-world use.

Artiphy closes this gap. We combine electrochemical modelling, machine learning and inverse-problem methods to infer hidden battery states and parameters from measurable signals such as current, voltage and temperature.

Where the physics is simple enough, we solve it directly. Where full simulations are too slow for inference, we use reduced-order models and AI surrogates to accelerate the workflow while retaining physical interpretability.

Key Capabilities

Next-generation battery intelligence powered by scientific machine learning

Battery model parameterisation

Estimate model parameters and stoichiometric alignment from current, voltage and temperature data, with uncertainty and identifiability checks.

Fast physics-based inference

ML-accelerated models make repeated electrochemical simulations practical for optimisation, uncertainty quantification and real-time inference workflows.

Hidden-state and degradation insight

Infer internal states, transport limitations, ageing mechanisms and safety-relevant indicators that cannot be measured directly.

Engineering Platform

Our platform provides GPU-accelerated surrogate modelling for electrochemical battery systems, with a primary focus on the Single Particle Model (SPM).

Core workflows include:

  • Forward Simulation: Evaluate voltage response V(t) from parameter vector θ and current profile I(t)
  • Parameter Inference: Estimate unknown model parameters from experimental current–voltage data
  • Surrogate Evaluation: Run trained neural network surrogates on cloud GPU infrastructure
  • Cloud Execution: Flexible input modes with structured result storage and CSV export

Supported Parameters

  • Solid diffusion coefficients (Dsn,p)
  • Particle radii (Rsn,p)
  • Reaction rate constants (kn,p)
  • Maximum solid concentrations (cs,maxn,p)
  • Ohmic resistance (Rohm)
