Saft Li-ion hybrid traction battery systems Eco-driving railways to increased energy efficiency
Next generation energy for a brighter, cleaner and more affordable future The rail industry has a well-earned reputation as a future-oriented, sustainable mode of transport. Recent years have seen great progress in making rail transport even more affordable, safe, competitive, reliable and above all environmentally friendly. New technology in areas such as hybrid traction is helping the rail industry to combine environmental friendliness with economic competitiveness through improved energy-efficiency. Lithium-ion (Li-ion) battery technology offers rail operators a route to significantly reduce emissions and operating costs by efficiently providing the power needed for hybrid traction and alternative power schemes.

Saft Li-ion hybrid traction battery systems: Delivering energy efficiency Saft Li-ion battery systems are capable of providing both high power and reserve energy resulting in increased energy efficiency for a variety of rail vehicles. Engineered for autonomous traction, regenerative braking and voltage stabilisation To provide autonomous traction power for catenary free or emission free operations To store kinetic braking energy (regenerative braking) and reuse it for autonomous traction and to assist with the acceleration of the train To maintain power quality for the local distribution network by preventing voltage drops and fluctuations at weak points (voltage regulation and stabilization) Designed for modularity to fit a multitude of rolling and running stock Light rail systems including trams, streetcars and tram-trains Electric-powered trains including electric multiple units (EMUs) Diesel hybrid / diesel shunting and freight locomotives / DMUs Automated People Movers (APMs) From start to finish, Saft Li-ion batteries ensure your train keeps on rolling Autonomous traction Accelerating Breaking regeneration Stop Stop Charging Discharging Discharging Charging Charging
Benefitting from cutting-edge technology Delivering high power and energy from a single source High rate charge and discharge capability for an always available system Highest power and energy density compared to any other commercially available technology Modular, lightweight and compact systems for easy plug and play installation Providing energy efficiency for reduced costs Regenerative braking improves energy efficiency with the potential for transit operators to save up to 30% of their energy costs Energy storage provides a reserve for use during periods of increased demand, when electricity costs are higher: facilitates peak shaving and/or demand management functions Elimination of overhead catenaries reduces both infrastructure construction and maintenance costs Increasing reliability for passengers and railway operators The onboard battery can provide sufficient autonomous traction power for the hybrid vehicle to continue its journey to the next station, for example during power outages Vehicle traction is maintained in locations where catenaries cannot be installed for security or safety reasons Worry free and safe operation are provided throughout the battery s life thanks to an integrated and proprietary Battery Management System Taking a stand to reduce the impact on the environment through innovation Diesel engine noise and particulate emissions are reduced by relying on battery power during idling Diesel engine fuel consumption or electricity usage on electrical trains is reduced by using the battery for hybrid traction The aesthetic appeal of transport systems is improved by eliminating catenaries especially in historic city centres by using the battery for autonomous traction Li-ion trackside energy storage systems Saft's Intensium Max Li-ion megawatt energy storage systems can be deployed trackside as part of a regenerative system that captures energy when trains brake and reuses it to help them accelerate. In addition to saving energy, the fully integrated containerized system serves a dual purpose by helping to increase network stability through frequency support. It can also generate further revenues by enabling the operator to sell excess energy reserve back to the local grid.
Offering maximum flexibility and modularity Battery bank concept offers scalability and flexibility - from kilowatts to megawatts Saft has developed a Li-ion battery bank concept that ensures scalability and flexibility. It is designed to suit the needs of the growing hybrid traction market. The standard battery bank has a nominal voltage of 250 V and is comprised of individual Li-ion modules. 250 V 500 V 750 V Battery bank concept is designed for easy mechanical assembly and scalability by multiples of 250 V The battery banks can be connected either in series or in parallel to provide the appropriate voltage and capacity. Mechanical assembly is made easy as the Li-ion battery banks can be placed either side by side or stacked on top of one another. The Battery Management System (BMS) provides real-time data management, ensured safety, and easy integration Interconnected battery banks are managed by a modular BMS which ensures the safety of the system and enables operators to manage data in real-time. The battery banks together with the BMS allow for easy integration and provide the ideal plug & play solution. To ensure optimum performance, reliability and safety, Saft Li-ion battery banks come complete with fully integrated electronic supervisory and power management systems.
