An Ultra-Fast Solver for Battery Performance
High-performance, physics-based solvers for the Newman model of Li-ion battery behaviour. Full electrochemical and thermal simulations in minutes, not hours.
Advanced Battery Modelling.
DandeLiion Technologies Ltd. builds validated high-performance, physics-based battery modelling software.
Thermal-Electrochemical Design
Fully three-dimensional tools capable of simulating large pouch, cylindrical and prismatic cells, and complete battery packs. Coupled thermal-electrochemical-degradation models solved exactly, rather than approximated.
Fast Battery Management Tools
Physics-based cell models designed to run within the tight computational limits of an on-board vehicle battery management system, bringing first-principles accuracy to real-time control.
Run simulations directly in the cloud on a scalable architecture. DandeLiion combines speed, scalability and raw computational power to shorten battery development cycles and deepen system-level understanding.
About:Energy, a world-leading innovator in battery parameterisation, has entered a technology licensing agreement with DandeLiion to advance battery modelling and accelerate electrification across the automotive and energy-storage sectors.

Examples
A selection of simulations run on DandeLiion. Each compares model output against experiment or demonstrates large-scale 3D performance.
Pouch cell heating during 5C discharge
A fully coupled thermo-electrochemical 3D simulation built from 9,600 coupled DFN models, showing heat generation across the cell during a demanding 5C discharge.
Tesla Model S battery module simulation
Temperature distribution across a complete module during a 1C discharge. A fully coupled thermo-electrochemical 3D simulation with liquid cooling, made up of 440 coupled DFN models.
Temperature coupling
Temperature distribution inside a 3D pouch cell, with the full DFN model solved in every finite volume. This single simulation solves more than 5 million coupled differential-algebraic equations.
Drive Cycle simulation
A half-hour fragment of a drive-cycle simulation (red) compared against experiment (black). The relative error (orange) never exceeds 1%.
Charge / discharge experiment
An LG M50 cell simulated under a realistic, time-varying current demand.
Commercial NCA/Gr-Si battery discharge
A high-energy 21700 NCA/Gr-Si cell discharged at two different temperatures, with results compared directly against experiment.
High-current Drive Cycle simulation
A high-current drive cycle with a highly non-uniform current profile, where peak charge and discharge currents reach 10C.
Secondary variables
A constant-current (1C) charge and discharge of a commercial Kokam 7.5 Ah pouch cell. Both microscopic and macroscopic variables — lithium-ion concentration in particles, potentials and more — can be saved at user-defined times and post-processed offline.
GITT experiment simulation
A 21700 NCA/Gr-Si cell undergoing a Galvanostatic Intermittent Titration Technique (GITT) experiment, with measured current and voltage in excellent agreement with simulation.
GITT simulation (zoomed-in)
A zoomed-in view of the GITT comparison, highlighting just how closely simulation tracks experiment.
