The objective of MAXITHERM is to contribute to the expansion of Electric mobility by extending Electric Vehicles' autonomy. We propose a heating system for EV that reduces electricity demand of heating systems by 30% while maintaining passenger comfort. MAXITHERM is a heating system based on a technical textile composed by a blend of electrically conductive and non-electrically conductive fibres that is integrated within the structure of the vehicles. It provides direct and fast heat to passengers and is 32% more cost efficient that current solutions.
