kWThe BYD Atto 3's climate system stands out for incorporating a standard heat pump integrated into its thermal management platform. This technology makes the difference compared to traditional resistive heaters:
It works in the reverse way of a refrigerator. It absorbs the waste heat from the electric motor, the inverter and the outdoor air to compress it and heat the cabin. For every electrical kWh consumed, it is able to deliver between 2 and 3 kWh of heat (a COP of 2.0 to 3.0), achieving an efficiency of 200% to 300%.
Conventional heaters (PTC) work by passing current through a resistor. Their maximum physical efficiency is 100% (a strict COP of 1.0). Thermally charging the cabin in winter based on PTC generates a brutal drain of energy directly from the main traction battery.
The highest climate consumption occurs when starting cold to bring the cabin from 0°C to 21°C. If you schedule the climate 15 minutes before leaving while the car is charging, that initial energy comes from your home plug, protecting both the trip range and the life of the cells by starting warm.
