Congress: Detailed Analysis of Regenerative Energy when the Electric Bus Driving on Expressways

Event: FISITA World Congress 14-16 September 2021 online

Name: Yiyuan Fang, PhD student

Company: Waseda University, Electric Vehicle Laboratory

Presentation Title: F2020-ADM-027 Detailed Analysis of Regenerative Energy when the Electric Bus Driving on Expressways

Please introduce yourself briefly…

I am a Chinese student studying for a PhD at the Graduate School of Environment and Energy Engineering, Science and Engineering Faculty, Waseda University, Tokyo, Japan. I like cars and driving very much, so my research field is electric vehicles.

What you will talk about at this year’s FISITA World Congress?

  1. Detailed analysis of regenerative energy when EV driving on expressways.

  2. Construct a theoretical formula for calculating regenerative braking energy.

  3. Regenerative brake setting improvement proposal.

What benefits will participants gain from your presentation?

Participants will learn about the following in my presentation:

  1. Comparison of regenerative braking conditions and effects of EVs (Ordinary roads / Expressways).

  2. Consider the energy calculation method of regenerative braking.

  3. Regenerative brake setting improvement proposal for expressway driving conditions.

Which trends do you consider as the most important for your domain of research and your geographical region?

For environmental reasons, electrification is a trend in the automotive industry in recent years. The current mainstream solutions are: HEV, BEV, PHEV, FCEV. I have observed that HEV is spreading far faster than the other three solutions in Japan. And, HEV, BEV, and PHEV are developing rapidly at a similar speed in China.

BEV has the advantage of simple power system configuration, but increasing its range is a major challenge

What challenges do these trends present?

BEV has the advantage of simple power system configuration, but increasing its range is a major challenge.

And what opportunities do these trends offer?

There are many ways to increase the range of BEVs, such as developing a more energy-efficient power system and optimizing regenerative brakes.

About the FISITA World Congress

Since 1947, the FISITA World Congress has been the leading international meeting place for industry experts, engineers and executives to exchange ideas and discuss the trends that drive the automotive industry forward. The theme for the 38th FISITA World Congress is 'From automobile to mobility. New roles. New challenges' and it will take place 14-16 September 2021, with the opportunity for the global audience to join virtually available for the first time. Registration is now open, with the Early Bird and special registration rates available until 31 August 2021.

Content from the 2020 FISITA Web Congress is available within the FISITA Technical Library, while material from previous Congress events back to 1998 is available in the FISITA Store. By the time of this year’s Congress, all the content will be available within the FISITA Technical Library, with free access provided to FISITA members.
