(Regenerative Power)

When a train set is braking, it generates energy which can be used by the adjacent accelerating trains. But in most cases, this regenerative energy is not e�ciently utilized by the next train and is wasted as heat through onboard or wayside resistors. Such cases does not only incur energy wastage but also likely to cause abrupt shift from regenerative braking to mechanical braking. This sudden change may further cause passenger ride discomfort and degradation of the brake shoe due to abrasion.

Toshiba developed Traction Energy Storage System (TESS) with SCiB™, a new energy saving solution with Toshiba’s own battery technology of high quality.

Toshiba’s Traction Energy Storage System e�ciently stores surplus regenerative energy in the SCiB™ and discharges it to another accelerating train. TESS is installed with Toshiba’s patented advance control system which allows �exible control of charge-discharge cycles in accordance to the battery’s State-of-Charge (SOC). This allows signi�cant increase in battery lifetime.

High performance SCiB™TESS utilizes Toshiba’s own high performance SCiB™This battery has various outstanding characteristics. By using unique oxide materials, SCiB™ holds high resistance against thermal runaway caused by internal short circuiting brought about by physical stresses.

Advanced V-SOC Battery ControlToshiba also developed a completely new and advanced Charge-Discharge algorithm for the e�cient control of TESS.For conventional energy storage systems, battery is charged and discharged to keep speci�ed SOC (State of Charge). Thus, battery is charged and discharged regardless of the feeding voltage. There will be instances when the battery will be unnecessarily charged/discharged even at rated line voltage (area between the Charge Start Voltage and Discharge Start Voltage). Thus causing feeding voltage imbalance and shortened battery lifetime.  As for Toshiba’s advance V-SOC control method, charge and discharge characteristics automatically shifts depending on SOC. When SOC is high, charge-discharge characteristic will shift to the higher voltage side, hence the battery shall be easily discharged. On the other hand, when SOC is low, charge-discharge characteristic will shift to the lower voltage side thus, battery shall perform more charging. The lifetime of a battery strongly depends on the charge-discharge times and current. By using this control algorithm, unnecessary charge and discharge can be greatly reduced.

Toshiba’s system does not de�ne any certain SOC which means that charge and discharge will be performed dynamically within a wide range of SOC.

SCiB™’s remarkable charge- discharge e�ciency characteristics can reduce energy wastage and ultimately, promote power demand peak cut.

Stored energy can be utilized to accelerate the trains and safely bring passengers to the nearest station during power failure. This function is most applicable when installed in tunnel and bridge sections.

TESS for Energy Saving

Tokyo Metro – Ayase Substation Field Test Results500kW TESS was installed in Ayase Substation of Tokyo Metro for energy saving and emergency power supply. TESS was able to independently power a 10-Car Train including all its auxiliary equipment (air conditioners, etc.) through a 2.4 kilometer distance from Ayase Station to Kita-Senju Station. This distance has a section with steep gradient of up to +33‰. Even at this stringent condition, TESS was able to safely power the train in a power failure condition.

500kW TESS was installed in Sueyoshi Substation of Okinawa City Monorail. With TESS operation, 10% power peak cut was achieved in Sueyoshi SS power consumption alone. Signi�cant power peak cut was also achieved in total power consumption in all substations.

With TESS, daily traction energy consumption was reduced to 575kWh/day (-17%) during weekday and 883kWh/day (-32%) during weekend while reducing the adjacent substation energy consumption as well.

TESS for Emergency Power Supply

Tobu Urban Park Line – Unga Station Battery Post During the adaptation of new type of cars, signi�cant loss in line voltage was expected to occur between Noda Substation and Toyoshiki Substation (11.65km distance). To stabilize line voltage in this section and avoid building new substation, 1000kW TESS was installed as a battery post.

TESS was able to stabilize line voltage �uctuation without having to build a new substation. Furthermore, power peak cut was also achieved through the e�ective use of regenerative energy.
