Directly-cooled lighter-weight EV motor made with polymer housing

Green Car Congress

Researchers at the Fraunhofer Institute for Chemical Technology ICT are working together with the Karlsruhe Institute of Technology KIT to develop a new cooling concept that will enable polymers to be used as EV electric motor housing materials, thereby reducing the weight of the motor and thus, the EV itself. Coolant circuit in the stator.

EPoSil: electroactive polymers for generating electricity from wave power

Green Car Congress

A German consortium involving four companies and and two universities is developing dielectric elastomers (electroactive polymers) for the conversion of mechanical energy—in this case wave power—into electrical power. This is an essential part of the electroactive polymer that converts mechanical energy into electrical power.
