High-speed, very high speed and tilting trains

Saft on-board battery systems perform two distinct, but important, functions on high-speed and tilting trains: low-voltage system back-up and braking and tilting system support.

Low-voltage system back-up

The on-board batteries must provide up to 90 minutes of back-up power for vital systems such as:

• lighting
• ventilation
• air-conditioning
• computers
• door controls
• communications

Braking and tilting system support

On-board batteries are also required to power for emergency braking and/or tilting systems that require a high current for short periods of time.

Battery solutions

Saft MRX, SRA LT/HT, MSX, SRM+ and SRX Ni-Cd batteries and NHM Ni-MH batteries are designed to meet the specific performance and safety needs of high-speed and tilting train applications. They offer:

• reduced weight and volume
• low maintenance and ease of servicing
• optimised LCC (Life Cycle Cost) and TCO (Total Cost of Ownership)
• flame retardant characteristics

Battery systems

Saft has extensive experience in meeting the needs of rail operators who require a complete battery system, and has developed nine standard systems for new build trains.

Saft can take responsibility for the whole battery design, development and manufacturing process by acting as a fully integrated, single-source supplier – from initial concept to volume supply. The result is a bespoke battery – tailored to meet the customer’s exact dimensional and performance specifications – that is supplied fully tested and qualified, and ready to ‘plug and play’.
