Ｎ７００Ｓバッテリ自走システムの開発について

抄録

In N700S Shinkansen rolling stock, we achieved weight reduction of the traction system that contributes to make space for new equipment under the floor of the car body. By using the created space, a self-traction battery system was developed in order for the train to propel itself to be prevented from stopping at any tunnels and bridges between Tokyo and Shinosaka in case of power failure of catenary caused by earthquakes and other natural disasters etc. The self-traction battery system was verified by conducting running tests for the future revenue service. In this paper, we introduce the design concept of battery, the entire batter system and the results of running tests.
