v0.2.0 - Temperature-aware battery modeling

Highlights

• Adds a temperature-aware battery equivalent-circuit example in base MATLAB.
• Couples irreversible electrical losses to a single-node thermal energy balance.
• Feeds lumped cell temperature back into ohmic resistance.
• Includes plotting and no-plot entry points, explicit assumptions, physical bounds, and an energy-conservation assertion.
• Documents the expected 37.32 degC peak temperature, 28.95 degC final temperature, 33.32 W peak irreversible heat, and 0.608 final SOC for the included pulse case.

Validation

• MATLAB R2026a mlint reports no findings for both new scripts.
• The pull request link-check workflow passed.
• An independent execution of the same discrete equations reproduced the documented outputs and a thermal energy-balance residual below 1e-6 J.
• Full local MATLAB batch execution was unavailable because the installed R2026a instance could not obtain a license; run check_battery_thermal_model in a licensed MATLAB session for native execution.

Scope

This remains an educational reference model. Parameters are not fitted to a specific cell, and the model excludes spatial gradients, reversible entropic heat, aging, hysteresis, thermal runaway, and pack-level interactions.
