Input
Defined electrical loading
Apply traceable charge and discharge conditions to establish the operating point.
Isothermal calorimetry
Measure battery heat precisely enough to improve the model.
Isothermal calorimetry turns battery heat flow into controlled experimental evidence for efficiency assessment, thermal-load definition and validation of cell-level thermal models.
Method
Separate measured heat from assumed heat.
Controlled current profiles, thermal boundary conditions and heat-flux measurements support repeatable comparison across battery operating points. The result is a stronger basis for efficiency specifications and for parameterizing models used in cooling-system design.
Measurement
Heat-flow evidence
Quantify thermal output under controlled isothermal conditions.
Analysis
Efficiency and thermal KPI
Relate electrical energy transfer to measured thermal losses.
Use
Model validation
Compare experimental results with predicted cell behavior and refine assumptions.
