EVS 2016 - 29th International Electric Vehicle Symposium | Year: 2016

When putting electric buses into practice in mass transit systems, the vehicle state management becomes a vital factor in the realization of a stable commercial operation. Aiming at achieving a sound bus operation, we installed a vehicle monitoring system on our own conversion E-Bus and realized remote vehicle control and driving data logging. In this manuscript, we are presenting a track record of the E-Bus and the vehicle monitoring system introduced in the JR (Japan Railway) Kesennuma Line which was severely hit by the Great East Japan Earthquake on March 11, 2011 and later temporarily restored as the BRT (Bus Rapid Transit).

EVS 2010 - Sustainable Mobility Revolution: 25th World Battery, Hybrid and Fuel Cell Electric Vehicle Symposium and Exhibition | Year: 2010

Electric vehicles (EVs) have been developed with the aims of saving energy and reducing carbon dioxide emissions. Furthermore, as a single bus can transport many people, buses produce low carbon dioxide emissions per person in comparison with cars. In recent years, community buses have been introduced nationwide to ensure the mobility of senior citizens. Therefore, a low-floor vehicle was adopted as the base vehicle in our latest project. The bus was demonstrated around the center of Toyama City. It was followed a circular route of distance 7.2km, the number of bus stops on the route was 27 and the driving time was 40 minutes per circuit. This demonstration was repeated three to four times a day for 14 days. During the 86 circuits of the demonstration, a total of 1,110 passengers used the bus and the total running distance was 776km. From these results, we concluded that the quantity of carbon dioxide emissions can be reduced by 37% using our proposed bus in comparison with that of a conventional diesel-engine bus.

2013 World Electric Vehicle Symposium and Exhibition, EVS 2014 | Year: 2014

We developed an EV conversion kit for light truck to promote 'pure (battery)' commercial EV. Operation of EV trucks can be arranged according to the capacity of battery installed generally because light trucks for deliveries inside cities are used in limited areas, fixed routes and scheduled operation time. Light delivery trucks are mostly used in food industry to make small amount deliveries and most of such trucks are equipped with freezer-refrigerator. We mounted a freezer-refrigerator on the converted EV truck, optimized the specification through demonstration and validated amount of CO2 reduction. © 2013 IEEE.

With the aim to improve technologies for EV or new energy industries and to create society with low environmental impact, Akita Prefecture has carried out the 'EV Bus Technology Improvement Project'. The project developed an Akita-original electric bus and it further aims to operate the E-Bus on regular bus routes throughout the year. © 2013 IEEE.
