The Smart BEST is an experimental Japanese two-car self-charging battery electric multiple unit (BEMU) train developed and manufactured by Kinki Sharyo in 2012 to demonstrate the feasibility of battery train technology for use on non-electrified rural lines.[1] The name is an acronym for "Battery Engine Synergy Train".[1] The train has been tested on JR West and JR Shikoku lines since late 2012.[1][2]
The Smart BEST train operates using GS Yuasa LIM30H-8A lithium-ion storage battery modules[3] recharged in operation by a small-capacity "e-Brid Plus" diesel engine.[4] The train normally operates at a maximum speed of 70 km/h (43 mph), but is capable of 100 km/h (62 mph) over short distances.[4]

History

The "Smart BEST" train was unveiled to the media in October 2012 at the Kinki Sharyo factory in Osaka,[4] before being moved to Yonago, Tottori for test running on the Sanin Main Line, Sakai Line, and Hakubi Line.[5][6] It was returned to Kinki Sharyo in December 2012.[7] In December 2013, the train was moved to Takamatsu, Kagawa, and started test running on a number of lines in Shikoku, including the Kōtoku Line, Naruto Line, and Tokushima Line.[2]
From September until December 2014, the train was used in revenue service on promotional "Hello Kitty" services in the Wakayama area.[8]
