EV Winter Heat Pump Simulator
Not all electric cars handle Canadian winters the same way. Some older or cheaper EVs use a basic electric coil to heat the cabin — the same idea as a space heater — which drains the battery quickly and cuts your driving range significantly on cold days. Newer EVs use a smarter system called a heat pump, which is far more efficient in cold weather and lets you drive much further on the same charge. This tool shows you exactly how much range you could lose on a cold morning depending on which system your car uses, and how much money the smarter system could save you over a full Ontario winter.

Why Thermal Engineering Matters
Think of a heat pump like a refrigerator running backwards. Instead of burning battery power to create heat from scratch — the way a hair dryer does — it pulls warmth that already exists in the cold outside air, the battery pack, and the electric motor, then concentrates and moves that warmth into the cabin. Because it's moving heat rather than making it, a good heat pump can deliver up to 3 units of warmth for every 1 unit of electricity it uses. That's the difference between a tool that works with nature and one that fights it.
Here's the honest truth: once the temperature drops below about -15°C to -20°C, there simply isn't much warmth left in the outside air for the heat pump to grab. At that point, the car automatically switches on a small backup electric coil to top up the heat — similar to what a kettle does. This is completely normal and expected. The heat pump still does most of the work down to those temperatures, and the backup coil only kicks in for the coldest days of the year. For a Canadian winter, that means the heat pump saves you money on the vast majority of your cold-weather drives.
If you're shopping for a used electric car in Canada, checking whether it has a heat pump is one of the smartest things you can do. An EV without one will lose a much larger chunk of its driving range every cold morning — sometimes 30–40% less distance per charge. An EV with a heat pump typically loses only 10–20% in the same conditions. Over a full Ontario winter, that difference adds up to real money saved on electricity, and it means you're far less likely to feel anxious about making it to your destination on a cold day. It's a feature worth specifically searching for on any used EV listing.
