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. The name is an acronym for Battery Engine Synergy Train. The train has been tested on JR West and JR Shikoku lines since late 2012.
