Moulding method for pack covers

Materials firm Sabic has successfully moulded an EV battery pack top cover using low-pressure injection moulding (writes Nick Flaherty). The trial of the process is part of Sabic’s Bluehero initiative to show the manufacturability of large EV battery components using thermoplastic injection moulding. This specific form of...

Additive manufacturing advance in stator production

Researchers in the US and UK have used additive manufacturing (AM) to develop a 3D-printed motor with materials previously considered too brittle to use (writes Nick Flaherty). The researchers, at the University of Sheffield in the UK and the University of Wisconsin-Madison in the US, have developed a 10 kW prototype motor that they are scaling up to 40 kW for e-mobility applications.

Carbon fibre made from sawdust

Researchers at the Bernal Institute in the University of Limerick (UL) are developing processes to create sustainable carbon fibres for car structures and batteries (writes Nick Flaherty). The processes use lignin, which is found in the walls of plant cells and is the second most common carbon material after cellulose.

Zero-emissions barge in world first

Dutch shipping company Future Proof Shipping (FPS) has launched the first hydrogen-powered zero-emissions inland container ship (writes Nick Flaherty). The H2 Barge 1 was developed in partnership with sports company Nike and the BCTN Network of Inland Terminals. The 110 m-long, 11.45 m-wide ship will sail between Rotterdam and BCTN’s inland terminal in Meerhout several times a week.

Simulators simplifies e-train design

A new version of the Spice analogue simulator called Qspice can simplify the development of motor control for EV powertrains and other vehicle motors (writes Nick Flaherty). The Qspice simulator has been written by Mike Englehardt, the creator of several versions of the Spice analogue simulator. It can integrate digital elements such as controllers with no performance penalties alongside the analogue power device simulation.
