Aims

This unit addresses the theoretical aspects on the novel concepts in automotive engineering including electric drive systems and hybrid systems. As the main part of the unit, the design aspects, construction and operating principles are included. In addition, the efficiency, environmental concerns and other advantages of electric and hybrid systems and integrated into the content. Knowledge on different types of hybrid systems such as series, parallel and series-parallel as well as full electric vehicles and plug in hybrid systems are expected to be delivered.

Learning Outcomes

1.
Explain the operational deficiencies of traditional IC engines such as fuel efficiency, wastage of energy environmental pollution and describe the need of electric and hybrid drivetrains.
2.
Appraise the operational principles of hybrid drivetrains and compare with traditional IC engines and electric drivetrains.
3.
Illustrate the risks and hazards associated with electric and hybrid drivetrains and recommend safety precautions needed in operation and maintenance.
4.
Define performance characteristics applicable for hybrid and electric drivetrains and carry out vehicle performance tests.
