The heat pump acts primarily as a range extender that helps save battery power in the pure electric XC40 Recharge. When it’s cold outside, it transports thermal energy from either the ambient air or the battery and releases this energy to heat up the cabin. This transport of heat is provided by a compressor which consumes less energy compared to the car's standard electrical heater. And by also supporting the air conditioner to work more efficiently, the heat pump helps save electric energy at a temperature range from +5°C up to 25–30°C. The heat pump can also help warm or cool the battery to optimise performance and range during long trips or heavy loads.
