The UK has pledged to reduce emissions from the transport sector to zero by replacing all the petrol and diesel cars with zero-emission battery-electric vehicles by 2050.
The success of this will depend upon three key aspects: the technological advancements in EVs, robust charging infrastructure and the role of society in adopting the new transport system.
Compound semiconductors will play a crucial role in the development of EV technology; they find their application in the powertrains and power electronics required in an EV.
They have significantly higher efficiencies than Si-based modules and generate less heat, and hence need smaller cooling systems, thus reducing the weight. They are also being exploited for wireless charging devices for EVs.
