Application of surface-heating solutions in EV interiors to heat up

Automakers are experimenting with heated surfaces to provide optimal cabin heating without adversely impacting the driving range of BEVs.

Range is of utmost importance in battery-electric vehicles (BEVs) and automakers are working continuously to improve this feature. However, the heating, ventilating and air conditioning (HVAC) systems used for cabin-comfort features put a huge strain on the range of BEVs. Unlike internal combustion engine (ICE) vehicles, BEVs do not have an engine to act as a heat source that can help warm the cabin during cold climatic conditions. To do so, BEVs need to use a direct resistive-heating device, such as positive temperature coefficient (PTC) heaters. PTC heaters utilize PTC materials (ceramic elements) that exhibit a positive resistance change with rising temperature.
