context_page_description: A battery electric multiple unit, battery electric railcar or accumulator railcar is an electrically driven multiple unit or railcar whose energy is derived from rechargeable batteries driving the traction motors.
  Prime advantages of these vehicles is that they do not use fossil fuels such as coal or diesel fuel, emit no exhaust gases and do not require the railway to have expensive infrastructure like electric ground rails or overhead catenary. On the down side is the weight of the batteries, which raises the vehicle weight, and their range before recharging of between 300 and 600 kilometres. Currently, battery electric units have a higher purchase price and running cost than petrol or diesel railcars. One or more charging stations are required along the routes they operate, unless operation is on a mixture of electrified and unelectrified track, with the batteries being charged from the electrified track.
  Battery technology has greatly improved over the past 20 years broadening the scope of use of battery trains, moving away from limited niche applications.
context_section_description: From March 2014, a two-car battery electric multiple unit, the EV-E301 series with 1,500 V DC overhead wire and battery power capability, entered revenue-earning service on the 20 km (12 mi) long non-electrified Karasuyama Line.
  Since March 4, 2017, battery electric trains have completely replaced diesel multiple units on this route. There are four two-car sets in operation, each set equipped with a 190 kWh lithium-ion battery.
  
  The trains recharge their batteries at Karasuyama Station (the end of the line) via their pantographs, using a rigid conductor bar placed where the overhead wires would be, connected to the local electric grid. At the other end, at Hōshakuji, the Karasuyama Line meets the electrified Tohoku Main Line. The trains then continue over the electrified Tohoku Main Line to Utsunomiya, where passengers can change to Shinkansen high-speed trains.
