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 System or Dynamic Power Supply System) 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.

Effectivity of Trolley Technology in Converting Mining Dump Trucks to EVs

Jun Ikeda･Yohei Nakate･Kiminori Saitou･Takayuki Satou (Hitachi Construction Machinery)

Mining companies are seeking zero-emission mining dump trucks, but changing the power source from engines to batteries poses challenges due to the operating characteristics of mines. An effective way to solve this problem is to combine it with trolley technology.

Current Status and Issues of Dynamic Power Supply in the Railway Sector

Yoshihisa Hojo (Toyo Denki Seizo)

The railroad sector has long been electrified, and power is supplied while driving from overhead wires.
In recent years, some lines have been either de-electrified or abandoned due to the inability to sustain the cost of overhead line facilities.
In addition, there are some sections where trains cannot interchange due to differences in electrification methods.
This paper presents a survey report on the current status and issues of dynamic power supply in the railroad sector.

Development of an EV with a Large-Scale Photovoltaic System

Hidenori Mizuno･Katsuto Tanahashi･Takumi Takashima･Takashi Oozeki (AIST)･Toshio Hirota (Waseda University/AIST)

A demonstrative van-type photovoltaic-attached electric vehicle (PVEV), to be used as a local community bus, was developed. This presentation shows the specifications of the PVEV and some of the results obtained through test runs.
