Speech Title: Energy Management, Energy Sources and Power Electronics Techniques for Electric Vehicles
Abstract: Electric Vehicle represents the major energy storage in a mobility aspect. It is also significant energy storage to connect to the power grid for future energy management, There are numerous energy storage units/systems that can be used in a vehicle now and future. For example, Supercapacitors, Fuel cells, and batteries are the major energy storage units for Electric vehicles (EV). The performance of an EV is highly governed by its performance. The challenge is not only to develop very high-density energy storage, the safety, dynamics, power conditioning, and charging method are also important research and development areas. The commonly used hydrogen fuel cell and metal-air fuel cell could be important future energy storage for mobility. Its performance and potential as compared with the other high-performance battery is an interesting area for exploration. Besides the Li-ion battery, there are many other newly emerging batteries such as new forms of Li-ion battery and flow batteries. Also, the super-capacitor usually works in parallel with the battery. The associated application to electric vehicles, and also their power conditioning is now a hot research topic. The battery management system is one of the key technologies to make the battery to be successful. This technology is now being investigated for use in the second life battery obtained from retired vehicles. In this century, electric vehicle research is also extended to the electric vessel. The opportunity of the electric vessel also plays an important role in smart mobility and smart city. The talk will discuss the recent and future developments in energy management including fuel cell and battery technology and the associated electric engineering research for the application to electric mobility and how the V2G can be benefited the power grid. Discussion on the better usage of the energy storage, stability, carbon footprint of this technology to the power grid will be examined.
