Efficient surplus energy storage systems based on SCiB™ rechargeable lithium ion battery
Traction Energy Storage Systems
Traction Energy Storage System (TESS)
Toshiba’s Traction Energy Storage System with SCiB™ rechargeable battery for DC Railway Power Supply Systems is an energy-saving solution equipped with Toshiba’s own high-quality battery technology. TESS can not only be used for energy-saving purposes, but also as an alternative solution to building new substations and as an emergency power supply system in the case of power failures.
Features
TESS benefits the energy efficiency and reliable operation of railway networks. Braking energy is stored in the battery system based on SCiB™ modules and made available for other trains operating on the network. Simultaneously better regenerative braking operation, energy-saving, feeding voltage stabilization and emergency power supply are also achieved.
Benefits
- Improved Regenerative Braking: surplus regenerative energy can be efficiently charged and discharged to/from the SCiB™ modules, thus preventing regenerative brake failures
- Energy Saving: remarkable charge-discharge efficiency characteristics can reduce energy wastage and ultimately promote power demand peak cuts
- Line Voltage Stabilization: installation of TESS can improve traction power quality through voltage stabilization
- Emergency Power Supply: TESS enables train operation in emergency mode
