Simulate Li-ion cells and large battery packs in 3D with full electrochemical and energy-conserving thermal models. Explore cell designs, pack layouts and cooling strategies.
Advanced Battery Modelling
Compare pack layouts before building prototypes, identify thermal hot spots and assess cooling designs within weight and space limits. DandeLiion brings full electrochemical physics to battery engineering.
Thermal-Electrochemical Design
Full Newman/DFN electrochemical models coupled to energy-conserving heat generation. Resolve temperature gradients and uneven local discharge within large-format cells and across packs, including bespoke cooling systems.
Fast Battery Management Tools
Electrochemical pack models demonstrated on resource-constrained automotive BMS hardware. We tailor models and solvers to your application and computational hardware.
Run simulations in your browser or integrate the solver into your engineering workflow with our lightweight Python client. Cloud execution is available through the portal and API, with deployment on customer servers available for bespoke applications.
A spin-out from the Universities of Southampton and Portsmouth, built on the Faraday Institution's investment in multiscale battery modelling. Our partnership with About:Energy brings complementary expertise in cell parameterisation.
