HOW DO ELECTRIC CARS KEEP YOU WARM IN WINTER?

EV Channels Review

This video addresses the reported heating issues in Tesla Model 3 and Model Y vehicles during cold weather, using the situation as a springboard to explain the three primary EV heating systems: resistive, PTC, and heat pumps. The presenter clarifies that while resistive and PTC heaters are energy-efficient in converting electricity to heat, they significantly impact vehicle range on long trips due to high energy consumption. Heat pumps, conversely, are more efficient for overall vehicle range as they move existing heat rather than generating it. However, their effectiveness diminishes in extreme cold, potentially explaining Tesla's reported issues after switching to heat pumps. The video suggests that preconditioning the vehicle while plugged in is the most practical solution for most owners, despite acknowledging that liquid-fueled heaters might offer better performance in extreme conditions but add cost and complexity.
