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 be used not only 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 stabilisation 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 cut
- Line Voltage Stabilisation: Installation of TESS can improve traction power quality through voltage stabilisation
- Emergency Power Supply: TESS enables train operation in emergency mode
