Re-inventing the electric wheel

03 June 2014

IDTechEx finds that the worldwide sale of hybrid and pure electric cars will triple as everything about them is being reinvented.

The market is expected to reach $178.9billion in 2024, finds the report Hybrid and Pure Electric Cars 2014-2024. Changes include in-wheel motors, fuel cell cars and transformed battery.

Launches of production models of fuel cell cars are promised around 2015 by companies such as Hyundai, Toyota, Daimler and Tata Motors, and new technologies such as supercapacitors, SiC and GaN power components, switched reluctance motors, merged and structural electric components, contactless charging and harvesting heat, light and vertical movement are all factors in the new market. presented.

Very different options for the elements of an EV are now emerging. It may be possible to have flexible batteries over the skin of the car in due course. Sometimes such laminar batteries permit faster charging and greater safety. In about ten years’ time, structural components - load-bearing supercapacitors and batteries will save even more space and weight in the most advanced vehicles.
 
Vehicle electrics will be a greater part of the cost of the vehicle as they replace hardware and give greater safety and performance. Electrics will change radically from the introduction of wide bandgap power semiconductors to printed electronics.
 
There is scope for energy harvesting from shock absorbers, thermoelectric harvesting which will be viable around 2017 and there will be some local harvesting for devices around the vehicle (eg Fiat vision).
 
The report also looks are “radically” new functional systems with previously impossible shapes and functions that will transform e-car systems.
