Japan’s Toshiba has provided a 1,000kW traction energy storage system (ESS) for stable electricity supply to Tobu Railway, a local train operator.
The ESS will be installed at Unga station in the Chiba prefecture. The ESS comprises of lithium titanate batteries with a capacity of 387kWh and stores regenerative traction energy from train deceleration when trains accelerate from the station.
The system can also be configured to support other applications, including traction energy loss prevention and peak demand power management. The company claimed that the ESS enables efficient charging and discharging by offering a battery capacity ten times that of other typical traction storage systems.
The system is planned to operate from December 22.
According to Toshiba, the company aims to expand marketing of traction ESS and other products that facilitate efficient energy use of energy, to railway companies in Japan and overseas.
Eneres recently announced to offer Toshiba’s IT & Control Systems’ 10 kW/9.9 kWh single-phase systems to consumers for behind-the-metre battery storage installations.
