With the improvement of lithium ion battery technology, railway vehicle industry to accelerate the battery alone would drive the development speed of the vehicle. Japan has recently introduced a Shinkansen vehicles driving on batteries, while in South Korea, hyundai motor is speeding up the development of the technology fusion cell and hydrogen production train.
7, according to the railway vehicle industry, from 1 to start a new high speed railway vehicles & other; N700 S” Connect in Japan Tokyo and Osaka, fukuoka, 1069. 1 km high-speed rail line & other; Tokaido, sanyo Shinkansen years into a route for the new car, for the first time when the external power supply, solar portal, using battery power can light. N700S is one of the world's first use of battery-powered high-speed railway vehicles. The vehicle use Toshiba lithium ion batteries, electric trolley line from the air take at ordinary times, in charge at the same time.
N700S battery driving system is in response to a power outage or natural disaster such as dangerous situation. So far, if all of the high speed railway vehicles from an external power, the inside of the passengers will do. Parked train to run, need to wait for the power to access or use of the diesel locomotive traction. Due to the distance between the station in more than 10 kilometers of high-speed railway, the characteristics of maximum capacity of 1323 people, only 16 carriages, solar energy equipment, solar energy equipment, so can't quickly in a short time to evacuate passengers. Especially when the train stop at the bridge and tunnel, etc, the more serious problem.
N700S in an emergency, just on the battery can be moving at top speed of 30 kilometers. High speed railway vehicles will be a huge electric vehicles. Maximum range not publicly, but operators JR east Japan said: & other; Only rely on battery power, train from Tokyo to Osaka, 515. 4 km range out of all the Bridges and tunnels. ” In this interval, the longest bridge and tunnel length 1 respectively. About 4 and 8 kilometers. Previously, Japan is actively using Toshiba 2018 lithium ion battery, battery can be performed during blackout moving into the new train in Tokyo subway bolus of the paint will be secondary battery technology such as grafting to try on railway vehicles.
in the domestic, hyundai group is committed to using the battery drive train technology development. Modern Rotem plans in February this year in Singapore the new contracting urban railway vehicle in the event of an emergency can keep running on batteries. Because Singapore requirements & other; Considering the general road and railway lines overlap region features, train need to quickly get very period & throughout; 。 The industry believes that the domestic plans big also to carry out the distance between the station in more than 5 km wide area rapid rail transit enterprise, relevant market is expected to open. Modern Rotem Zheng Encheng power system leader ( The sound) Look forward to, 'said & other; Considering the extraordinary times such as the passengers' safety, solar equipment, we developed the battery self driving systems. From China began in 2018, will help to activate the orders in the world market. ”
in the meantime, solar power network, the modern Rotem based on the modern car hydrogen fuel cell system, is developing hydrogen fuel cell. Hyundai plans to hydrogen fuel commercial vehicle development experience transplantation on the railway vehicle, strive for in the next year or so to ensure that the technology. Only by hydrogen fuel cells, lithium ion battery for mobile and is expected to contribute to reduce the cost of railway infrastructure. In Japan, JR east Japan railway company and Toyota to empirically test next year as the goal, is to accelerate the development of hydrogen fuel rail vehicles.
