The {{Nihongo|EV-E801 series|EV-E801系|EV-E801-kei}} is a two-car battery electric multiple unit (BEMU) train type operated by East Japan Railway Company (JR East) on the Oga Line in Akita Prefecture in northern Japan since 4 March 2017.{{cite web |url= http://www.jreast.co.jp/press/2016/20161219.pdf|script-title=ja: ２０１７年３月ダイヤ改正について |trans-title=March 2017 timetable revision|date= 16 December 2016|work= News release|publisher= East Japan Railway Company |location= Japan|page= 4|language= ja|archive-url= https://web.archive.org/web/20161217143005/http://www.jreast.co.jp/press/2016/20161219.pdf|archive-date= 17 December 2016|url-status=live |access-date= 17 December 2016}}

Overview

The train is derived from the experimental 817 series BEMU train developed by JR Kyushu, and will incorporate modifications to cope with the colder climate of Akita Prefecture.{{cite web |url= http://response.jp/article/2015/11/20/264656.html |script-title=ja: JR東日本、男鹿線に蓄電池電車「EV-E801系」導入へ|trans-title=JR East to introduce new EV-E801 series battery train on Oga Line|date= 20 November 2015|work= Response |publisher= IID, Inc.|location= Japan|language= ja|access-date= 21 November 2015}}

The two-car EV-E801 series train operates as an electric multiple unit (EMU) under the 20 kV AC overhead wire of the Ou Main Line between {{STN|Akita|x}} and {{STN|Oiwake|x|Akita}}, a distance of {{Convert|13.0|km|abbr=on}}, and on battery power over the non-electrified Oga Line tracks between Oiwake and {{STN|Oga|x}}, a distance of {{Convert|26.6|km|abbr=on}}, replacing existing KiHa 40 diesel multiple unit (DMU) trains. It can also be recharged via its pantograph at a 20 kV AC recharging facility specially built at Oga Station.

The EV-E800 car is equipped with lithium-ion storage batteries with a total capacity of 360 kWh (at 1,598 V), and operates at a maximum speed of {{Convert|110|km/h|mph|round=5|abbr=on}} under overhead wires and at {{Convert|85|km/h|mph|round=5|abbr=on}} on battery power over non-electrified tracks.

Formation

The two-car train is formed as shown below, with one driving motor ("Mc") and one driving trailer ("Tc") car.{{cite web |url= http://www.jreast.co.jp/akita/press/pdf/20151120-1.pdf|title= 新たな「蓄電池電車」を男鹿線に導入します |trans-title=New battery train to be introduced on Oga Line|date= 20 November 2015|work= Press release|publisher= East Japan Railway Company Akita Division|location= Japan|language= ja|access-date= 21 November 2015}}

History

Initial details of the new train were formally announced by JR East on 20 November 2015.{{cite web |url= http://tetsudo-shimbun.com/headline/entry-551.html |script-title=ja: JR男鹿線に新型交流蓄電池電車「EV-E801系」を導入へ JR九州開発車両ベース|trans-title=New EV-E801 series AC battery train to be introduced on JR Oga Line - based on train developed by JR Kyushu|date= 20 November 2015|publisher= Tetsudo Shimbun|location= Japan|language= ja|access-date= 21 November 2015}} The train underwent evaluation and proving trials on the Oga Line prior to scheduled services in March 2017. The two-car trainset was delivered from the Hitachi factory in Kudamatsu, Yamaguchi to Akita Depot in December 2016.{{cite web |url= http://railf.jp/news/2016/12/10/203000.html|script-title=ja: JR東日本EV-E801系が甲種輸送される |trans-title=JR East EV-E801 series delivered |date= 10 December 2016|work= Japan Railfan Magazine Online|publisher= Koyusha Co., Ltd.|location= Japan|language= ja|archive-url= https://web.archive.org/web/20161210125347/http://railf.jp/news/2016/12/10/203000.html|archive-date= 10 December 2016|url-status=live |access-date= 10 December 2016}}

On November 2, 2020, two new sets G2 and G3 were delivered from Hitachi and arrived at Akita depot on November 4. The sets were coupled to each other and transported by a freight locomotive.{{cite web |url=https://4gousya.net/blog/archives/19932 |title=アキG2・G3編成4両日立製作所出場 |location=Japan |language=ja |access-date=7 November 2020 |date=4 November 2020}} Additionally on November 16, 2020, three more sets G4, G5, and G6 were delivered and arrived at Akita depot two days later.{{cite web |url=https://4gousya.net/blog/archives/20172|title=アキG4・G5・G6編成6両日立製作所出場|location=Japan|language=ja|access-date=18 November 2020|date=18 November 2020}}

In December 2023, a winter snowstorm stranded sets G5/G6 in the middle of Oga Line at a passing loop station, requiring a DE10 diesel locomotive to rescue both sets at the same time.{{Cite web |title=【JR東】EV-E801系G5編成、G6編成が、DE10-1759の救援により回送 {{!}}2nd-train鉄道ニュース |url=https://2nd-train.net/topics/article/52647/ |access-date=2024-12-04 |website=2nd-train |language=ja}}
