Sammanfattning
In recent years, the automotive sector has experienced a notable upsurge in the popularity of electric vehicles (EVs), as evidenced by the expanding array of EV models introduced to the market. This trend reflects a significant transition towards sustainable transportation solutions, promising reduced carbon emissions and decreased reliance on fossil fuels. However, alongside the promising prospects associated with the rise of EVs, there are notable challenges that must be addressed to facilitate their widespread adoption. A primary challenge confronting the adoption of electric vehicles pertains to battery technology. The current capacity and efficiency of batteries remain focal points for improvement. The constraints imposed by battery capacity directly influence the driving range of EVs, therefore impacting consumer confidence and adoption rates. Moreover, adverse weather conditions, particularly in cold climates, exacerbate these limitations by imposing additional strain on battery performance. The heating, ventilation, and air conditioning (HVAC) system is a significant contributor to energy consumption in EVs. In cold climates, the energy-intensive process of cabin heating assumes paramount importance, given its potential to significantly diminish the vehicle’s range. This thesis investigates radiation panels as an alternative approach to the heating of the cabin, alongside traditional heating done with warm air from the HVAC system and conductive heating from the seat and the steering wheel. A numerical model was developed in TAITherm software that simulates the heat up sequence of a cabin of an SUV-type car in -7◦C outside temperature. The model includes a driver manikin with a human thermal model, which calculates the human’s perceived sensation and comfort. A parameter space was defined for the simulations and a comparison between the cases was made.
