Session｜2024 JSAE Annual Congress (Spring)

Contents: Proliferation of electric vehicles (EV) is the key to reduce CO2 emissions while driving vehicles. However, there are issues which need to be solved such as cruising range, charging method, and spread of EVs among large-sized transport vehicles. We will discuss Electric Road System (Dynamic charge and power supply) technology using ground infrastructure to directly supply charge running EVs with electricity. In this session, various systems such as contact type (conductive type) and non-contact type (wireless type) will be discussed.
Committee: Vehicle Characteristics Design Committee
Organizer: Takamitsu Tajima (Honda R&D), Junya Yamakawa (National Defense Academy of Japan), Hitoshi Tsunashima (Nihon University), Yasuji Shibahata (Kanagawa Institute of Technology), Keiichi Koseki (Ibaraki University), Takayuki Satou (Hitachi Construction Machinery), Kazuki Shimamura (Japan Automobile Research Institute), Masaki Asano (Isuzu Advanced Engineering Center), Ryuzo Hayashi (Tokyo University of Science)

189	◯	Endurance Test Methods for Batteries Applied to Intermittent Charging during Highway Driving Yoshihisa Hojo (Toyo Denki Seizo) Intermittent charging during driving on highrways is being considered from the perspective of reducing battery capacity and equipment-related costs for heavy trucks and other vehicles.However, this method has an impact on battery life due to frequent charging and discharging. This paper proposes a test system using two dynamometers with a continuous rated torque of more than 6500 Nm to perform battery endurance tests on the bench.
190	◯	Proof of Concept of Trolley Technology in EV Conversion of Mining Dump Trucks Toshikazu Minoshima･Jun Ikeda･Takayuki Sato (Hitachi Construction Machinery) The mining industry is exploring the electrification of mining dump trucks to achieve net-zero emissions. Mine dump trucks powered by batteries instead of engines were operated at a mine with conventional trolley technology. This paper reports on the actual experiment at the mine site.
191	◯	Development of a PVEV Evaluation Tool Hidenori Mizuno･Bunme Pawita･Takumi Takashima･Takashi Oozeki (AIST) We have developed a 'PVEV Evaluation Tool' that estimates the potential benefits of PVEVs without actual usage. This tool will provide useful information to motivate manufacturers to develop PVEVs and assist users in making decisions about adopting PVEVs.
