Battery Mode Operation of the EV-E301 Series

Dropping the pantographs, EMU JR East EV-E301 series runs on the non-electrified track
 
As I reported before, JR East launched Japan's first accumulator train, the EV-E301 series on March 15th this year. Following the test run operation on the electrified track of the Tohoku Main Line (Utsunomiya Line), I am going to show you the scenes of the battery mode operation on the non-electrified track of the Karasuyama Line since starting commercial operations.

Please look at the top photo. You can see the EV-E301 series running on the un-electrified track between Kohnoyama and Oogane stations of the Karasuyama Line. Dropping its pantographs, the train is operated by the electric power supplied from two sets of 600V-95kWh lithium ion accumulators. I was surprised that the train had such a low noise level.

The following photo shows the scene of the train being charged at Karasuyama Terminal. After arriving at Karasuyama, the EV-E301 series is charged up at the charging facility for its return trip. You can see the train raising the pantographs and the short overhead conductor rail constructed above the train. "Nutritional support" is essential for the EV-E301 series before a 20.4km long return journey without electric supply from the overhead catenary.

Plenty of rail fans ride on this brand new train every day. While I was waiting for the return train at Karasuyama Terminal, I saw many local Boy Scouts, who were making a visit to the terminal to see the EV-E301 series. They listened intently to the railway employee's explanations about the accumulator train.

The battery mode operation of the EV-E301 series... so far, so good.
