Inputs
Current profile, resistance, thermal capacitance, ambient temperature, effective cooling conductance, and time step.
Validated reference · MATLAB/Python
Battery thermal response from an explicit energy balance.
A first-order model for sensitivity checks involving current, resistance, thermal capacitance, ambient temperature, and effective cooling conductance.
Governing equation
Cth dT/dt = I²R − hA(T − Tamb)
What the model exposes
The implementation makes heat generation and convective rejection explicit. It supports early sensitivity studies and discussion of cooling assumptions before higher-fidelity CFD, FEA, or electrochemical models are justified.
Research context
Published spatial modeling provides the higher-fidelity context behind the reduced-order reference model.
Engineering boundary
Useful for sensitivity; insufficient for qualification.
Outputs
Temperature trace and heat-balance response for the stated lumped assumptions.
Verification
Analytical state update and automated unit tests in the public repository.
Not included
Thermal runaway, electrochemical aging, spatial gradients, component tolerances, or safety certification.
