Parked Vehicle Temperature Calculator

Predict interior temperature over time using ambient temp, sunlight, paint color, ventilation, wind, and vehicle size.

Model: T(t) = T_ambient + (T_max - T_ambient) * (1 - e^(-k*t)), where T_max = T_ambient + (Solar * absorption) / (1 + ventilation + wind*0.1) and k scales by vehicle type.

Predicted cabin temperature at 30 min: 479.1°C (894.3°F)

Estimated steady-state maximum (T_max): 784.0°C (1443.2°F)


  • Vehicle factor: 1.00
  • Absorption factor: 0.90
  • Ventilation dissipation factor: 0.00
  • Thermal constant k: 0.0300 per minute

Parked Vehicle Temperature Calculator helps you predict interior temperature over time using ambient temp, sunlight, paint color, ventilation, wind, and vehicle size. It is commonly used by engineers, lab users, field operators for parked car temperature calculator, vehicle cabin heat predictor, car interior temperature.

Thermal model used

This calculator applies:

T(t) = T_ambient + (T_max - T_ambient) * (1 - e^(-k * t))

Where:

  • T_max = T_ambient + (Solar_Gain * Absorption_Factor) / (1 + Ventilation_Factor + Wind_Speed * 0.1)
  • k is scaled by vehicle type (car heats faster; bus/train have more thermal inertia)

Use it for safety planning and heat-risk awareness in parked vehicles.
