The BEC819 series (BEC819系), branded "DENCHA" (Dual Energy Charge Train), is a two-car battery electric multiple unit (BEMU) train operated by Kyushu Railway Company (JR Kyushu) on inter-running services over the Fukuhoku Yutaka Line and Chikuhō Main Line in Fukuoka Prefecture in northern Kyushu, Japan, since October 2016.

Design

Based on the earlier 817 series electric multiple unit (EMU) trains,[1] styling of the trains was overseen by industrial designer Eiji Mitooka.[1]

The lithium-ion battery system used has a capacity of 360 kW and operates at 1,598 V.[2]

Operations

The BEC819 series trains are used on through services over the Fukuhoku Yutaka Line electrified at 20 kV AC and the non-electrified Chikuhō Main Line (known as the "Wakamatsu Line") between Orio and Wakamatsu.
