D-WPT Installation and Characteristic Changes Due to Surrounding Environmental Factors

Jin Katsuya･Takeshi Hoshinoya･Kenichiro Takahashi (Honda R&D)

Proposing a burial method, verifying the influence factors due to the actual environment (soil, snow, asphalt pavement, etc.) with actual equipment, and evaluating changes in characteristics after 100,000-wheel durability and pavement roadbed evaluation before applying to general roads. We will make suggestions regarding inexpensive installation methods.

Feasibility Study of Onboard PV for Commercial Vehicle Application (2nd Report)
-Estimation of the On-board Effect of PV Systems by Simulation-

Shuai Pei･Jingxuan Peng･Kimiyoshi Kobayashi･Toshio Hirota･Yushi Kamiya (Waseda University)･Hidenori Mizuno･Takashi Ohzeki (AIST)

As an EV community bus field test was conducted in Iizaka Onsen area, Fukushima, EV’s energy consumption and solar irradiance under various driving and weather conditions were measured. Then, simulation models were developed to analyze the impact of EV energy consumption and PV generation, which are under different ambient temperatures, solar heights and driving conditions, such as various driving distance and route slope. Finally, the potential for electric energy reduction with installation of PV system was evaluated.

Benefit and Challenge Analysis of EVs Integrated with Photovoltaic Systems

Hidenori Mizuno･Katsuto Tanahashi･Takashi Oozeki (AIST)

This study focused on EVs especially used as delivery service vehicles, to analyze the potential benefit of integrating photovoltaic systems to the EVs and extract challenges to utilize such “PVEV” vehicles as efficiently as possible.

A study of EMC Tests during 150kW Class BEV Charging

Akira Mori (Toyota Motor)

Although BEV charging power is becoming high rate, study of EMC testing methods has not progressed accordingly. Therefore, in order to study a standard test method that assumes high power charging, we used the Fukushima Renewable Energy Institute which has dedicated equipment. And we conducted EMC tests during 150kW class BEV charging. It was confirmed that when the charging voltage is constant, there is no current dependence of conductive and radiated emissions.
