Saft back-up battery systems will support critical control and safety functions on 20 Alstom Metropolis trainsets that will carry 430,000 passengers a day on the new Lucknow Metro in India.
LUCKNOW: Saft has been awarded a major contract by Alstom India to supply the onboard back-up battery systems for 20 Metropolis trainsets for Lucknow’s brand new metro system. Lucknow is the capital of Uttar Pradesh, India’s most populous state. The city has grown to over three million people, creating an urgent need for an environmentally-friendly mass transit system to address traffic congestion and pollution issues. The SRM+ battery systems will provide the vehicles with up to 90 minutes of onboard back-up power if the main power is interrupted. This will ensure continuity of operation for critical control and passenger safety functions such as door operation, lighting and communications.
Saft has a strong presence in India’s fast-growing railway sector, with ongoing metro projects in some of the largest cities across the country. The Lucknow Metro Rail Corporation (LMRC) has ordered the vehicles for a new metro line, around 23 km long and including 22 stations. The 8 km first phase is scheduled to open in March 2017. The line is predicted to carry more than one million passengers a day by 2030.
“The Lucknow Metro will be the fastest and most economical high speed rapid transit system project in India. To achieve this goal, we have selected the very best components and subsystems,” said the project manager of Alstom India. “We specified Saft’s specialized rail batteries because they have proved their reliability and long life in a number of previous Alstom rail projects around the world.”
Each four-car unit will be fitted with a battery system based on Saft’s SRM+ 135 nickel technology cells that deliver high performance, reliability and a 15-year plus service life in a compact installation footprint. The battery systems were designed and engineered by Saft’s team in Bordeaux, France where the SRM+ cells are manufactured. The battery systems are assembled by Amco Saft using battery boxes made locally in Bangalore, India.
“The Lucknow Metro project further reinforces our global cooperation with Alstom on major rail projects. It also continues Saft’s substantial penetration into India’s metro sector that has already seen our batteries specified on rolling stock in cities including Delhi, Kolkata, Bangalore and Chennai” said Guy Patrick de Broglie, Saft General Manager India. “The approach taken, with cells produced in France for local assembly into battery systems is an important step towards more substantial localization of key elements of our rail projects in India.”
Saft delivered the first two battery systems in September 2016. The order is scheduled for completion by the end of 2017. LMRC has ordered the vehicles for a new metro line, around 23 km long and including 22 stations. The 8 km first phase is scheduled to open in March 2017.
SAFT’S C.O.M.M. Batt harnesses the internet of things for the remote monitoring of backup batteries
At the recently held InnoTrans 2016 at Berlin, Saft announced launching of its groundbreaking battery monitoring solution that combines remote, wireless real-time data monitoring and collection with advanced modeling algorithms.
Batt, its first ever Internet Of Things (IoT) service for nickel-based onboard batteries. The new service now enables rail operators to realize the benefits of predictive maintenance planning for their backup batteries based on remote, real-time monitoring e.g. reduced downtime, optimized fleet management and the associated cost efficiencies.
Saft has developed the C.O.M.M. Batt service as an innovative element within its global improvement program to further improve life-cycle costs (LCC) and maintenance intervals for its nickel-based batteries. C.O.M.M. Batt uses wireless technology to transmit a wealth of diagnostic data. This data is analyzed using Saft’s advanced modelling algorithms based on real-world knowledge drawn from a vast installed base to provide information on battery operation and charge condition as well as key predictive maintenance information. Operators can see a real-time picture of how their batteries are performing and can access this information on a PC or a smart phone and receive message alerts.
C.O.M.M. Batt provides an effective basis for a transition to a predictive maintenance regime, rather than corrective and preventive maintenance, which yields other benefits such as lower maintenance costs and, increased fleet availability. C.O.M.M. Batt represents a flexible philosophy that can be adapted to suit specific train equipment, communication protocols and operator maintenance workflows.
The other highlight of Booth 205 in Hall 15.1 is Saft’s high-tech lithium-ion (Li-ion) battery systems for hybrid and autonomous catenary free traction applications as well as for supporting electricity infrastructure serving public transport systems. Also on display is Saft’s range of specialized nickel-based battery solutions for onboard auxiliary power and engine starting applications.
Li-ion technology powers traction and supports infrastructure
Saft’s Ion-OnBoard® modules harness the specific advantages of Li-ion technology, such as high power, lightweight design, compact footprint and maintenance-free operation for rail traction applications. They complement diesel-electric generators in hybrid installations by accommodating highly dynamic charge-discharge cycles to provide peak power for acceleration and recovering energy from deceleration and braking. They are also ideally suited for electric drive applications that ensure autonomous, catenary-free operation for trams and light rail vehicles over unpowered sections of track.
Saft’s Intensium® Max containerized Li-ion systems also feature in stationary wayside energy storage installations to support the electricity infrastructure serving public transport systems, particularly in optimizing power flows by recovering braking energy from trains.
An outstanding global track record in reliable backup and engine starting
Saft’s innovative nickel-based battery solutions contribute to the reliable and successful operation of more than 100 rail networks worldwide in even the most demanding conditions, including extremely low and high temperatures. Saft’s outstanding track record is founded on over 60 years’ experience in the design, development and volume delivery of battery systems that support critical onboard safety, control and passenger comfort systems as well as effective engine starting. At Innotrans, Saft is showing 11 specialized battery ranges that meet all needs from 2 kWh to 420 kWh, with the emphasis on performance and reliability over an extended life of up to 20 years. Thanks to a low maintenance design, with service intervals from five to 10 years, and a near zero corrective maintenance cost, Saft rail batteries enable operators to achieve an optimized Total Cost of Ownership (TCO).
