Manchester team proposing graphene-based ballistic rectifier for waste heat recovery

Green Car Congress

Rectifying diodes let electrical current flow in only one direction; mainly used for power supply operation, they convert AC to DC current. Graphene was the world’s first two-dimensional material, isolated in 2004 at The University of Manchester; since then a whole family of other 2D materials have been discovered. —Song et al.

It enables electric cars to be charged with direct current (DC) and alternating current (AC) using the standard Combo 2 connector. The majority of stations currently available on the market support DC charging with 50 kW. An AC/DC converter inverts the current, which is then fed into the high-voltage electrical system.

The next-generation Toyota Prius

Green Cars News

And when operating in EV mode at speeds up to 30mph, it uses no fuel and produces zero exhaust emissions. Adopting the Atkinson cycle and a new, cooled exhaust gas recirculation system brings significant gains in fuel efficiency and emissions reduction. As a result the exhaust temperature is lower than that of conventional engines.
