E-motors are the driving force behind Electric Vehicles (EVs), currently leading the global efforts for decarbonisation of the transportation sector. Unfortunately, electrification of commercial or heavy-duty vehicles, earth-moving machines and aircrafts have to overcome, among other significant limitations (such efficient energy storage and battery weight, safety, limited availability of carbon-free fuels, cost etc), the technological barrier of excess e-motor heat generated during power-demanding operations.

The long-term vision of E-COOL is to address this challenge via the development of a breakthrough direct-contact, spray cooling system. The envisioned technology aims at an unprecedented cooling rates at the local temperature hot spots and result to an average 20% increase in e-motor efficiency compared to today’s state-of-the-art. In an equally important manner, the developed technology will also allow utilisation of e-motors in power-demanding applications, currently prohibited by the excess temperatures generated. These applications expand over the whole range of transportation sectors and, thus, they will contribute to EU’s decarbonization strategy, via significant additional energy and CO2 savings relative to the ones currently envisioned from existing regulations. Moreover, E-COOL aspires to achieve this technological breakthrough at time-scales compatible to those required for industrial innovations to reach the market.
