Toshiba Supplies Traction Energy Storage System for Tobu Railway

TOKYO - Thursday, December 18th 2014 [ME NewsWire]

(BUSINESS WIRE) - Toshiba Corporation (TOKYO:6502) today announced that it has supplied a traction energy storage system (TESS) to Tobu Railway Co., Ltd. TESS stores traction energy generated by decelerating trains as they enter a station and releases it as needed when trains accelerate from the station. The system is planned to operate from December 22.

Toshiba’s TESS is installed at Unga station on the Tobu Urban Park Line, and utilizes Toshiba’s SCiBTM rechargeable batteries to store regenerated power. SCiBTM offer outstanding characteristics, including a high degree of safety, a wide state-of-charge (SOC) range*1 and stable operation at low temperatures. Toshiba’s TESS realizes efficient charging and discharging by offering a battery capacity ten times that of typical traction energy storage systems*2, and also employs the company’s proprietary charge-discharge control technology, which takes full advantage of the wide SOC range of the SCiBTM.

At Unga Station, regenerative traction energy from train deceleration is stored in the TESS for supply as needed when trains are accelerating from the station, facilitating stable electricity supply.

In addition to supporting stable supply, the system can also be optimally configured to support other applications, including traction energy loss prevention and peak demand power management.

Going forward, Toshiba intends to proactively expand marketing of traction energy storage systems and other products that facilitate efficient energy use of energy, to railway companies in Japan and overseas.
