Electric vehicles are the future of transportation. Electric mobility has become an essential part of the energy transition and will imply significant changes for vehicle manufacturers, governments, companies, and individuals. 

Electric Vehicles have completely different systems & architecture compared to petrol or diesel vehicles. Example,

• Heating Ventilation Air Conditioning (HVAC) system is completely different compared to the one which is used in IC vehicles. As there is no engine, the compressor needs to drive by a separate drive unit and there is no engine cooling system that can be used for cabin heating. In EV’s the HVAC unit is completely different. (The need for understanding: Mid-size sedan’s  HVAC system size is about 1.5 to 2.5 kW, on full load operations, the impact of energy consumption by HVAC can drastically reduce the range of vehicle)

• Auxiliary loads in EVs are higher, and 12V system architecture for auxiliary loads used in IC vehicles may not be sufficient to be used in an EV auxiliary system (These intricate details and ability to analyze can be understood only when you have the system-level knowledge)

• Components like vacuum-assisted braking can now require a different system as there won’t be an engine to create the vacuum

Like the above examples, EV is a very complicated system than ICV’s. If you like to explore opportunities in EV sector, you need to have a deeper understanding of the system, it’s dependencies & interconnections, sizing, operating conditions, dynamic behaviours & more. So you appreciate the technology & work which beyond the books & internet collected course contents.

This course brings you deeper insights to understand the electric vehicle technologies and gain appreciable command over the systems. By the end of the course, you will have a theoretical understanding of the system, visualization of real vehicle components, numerical calculations, and analytical understanding of system sizing and you will build the motivation to learn more as you will appreciate the technology.
