RECOM'S RMOD families are robust plug & play modules which are used to generate the low voltage network for a vehicle's traction battery

Railway carriages, vehicle locomotives and multiple units are constructed “inside-out”. First, the chassis and frame are assembled inside a giant cradle. Then the flooring and internal walls are added. The whole carriage can then be rotated to assemble the equipment built onto the roof space (lighting, air conditioning, CCTV, door actuators, electrical cabling, etc.) and the heavyweight stuff is built into the underbody space (braking controllers, traction systems, air compressors, vacuum pumps, etc.) Only when all of this is complete, are the windows and outer skin of the carriage fitted.

Coach bodies are assembled this way to make it easier to fit all the electrical and electronic equipment, cabling and sensors needed for a modern railway carriage. As with any complex electronic systems, ensuring a clean and reliable power supply is essential, so the EN50155 standard for electronic equipment in rolling stock is the basic specification for designing such power supplies, detailing the technical, EMC and environmental requirements.

However, assembling a complete power supply system requires more than simply assembling different power supply units together. Just as the carriage needs to be built bottom-up, so does the power supply infrastructure.

At the “front-end”, new power generation technology such as fuel cells and battery hybrids need multi-kilowatt AC/DC and DC/DC converters and chargers. RECOM provides several charger solution families in the power range from 1,5kW up to 18kW as modular and cascadable units including intelligent interfaces such as CAN J1939 and temperature regulated output voltages including split operation.

At the “plug-and-play” area, flexibility is called for. These units are designed for equipment that needs a standalone or an external power supply or for any equipment that needs fully approved units. RECOM’s RMD Families are ready to use, where easily a complete certified unit can be implemented without having to design the PSU with an extra PCBs, without any external/extra circuits and especially without any trouble of certifications and approvals. Modular, all-in-one, chassis mountable, easily swappable, power supply units need to be available for any kind or railway systems.

At the “back-end”, compact and robust DC/DC converters are used to provide local power. Isolating each functional part with its own independent power supply ensures that there is no crosstalk between them and increases fault tolerance.

RECOM offers a product range that covers front-end, back-end and plug-and-play solutions, all from one experienced source. Visit the company at InnoTrans to find out more.


Hall 11.1, Stand 260

Leclanché’s INT-53 Energy Battery Pack

At InnoTrans 2022, Leclanché, a global leader in the electrification of fleet vehicles – from trains to ships, trucks, and specialty vehicles – will display its full range of lithium-ion battery solutions specifically designed for the railway industry.

The company manufactures its own cells to exacting standards in Germany. It has become a benchmark in lifecycle and total cost of ownership for rolling stock and locomotive applications with a service life of up to 10 years and hence providing tremendous savings in battery replacements. Leclanché cell technology has been specified for use in North America and Europe by some of the industry’s largest rolling stock manufacturers and operators.

In addition to its cells, Leclanché manufactures modules on its state-of-the-art automated assembly line, in Yverdon, Switzerland. These modules are assembled into packs with proprietary functionally safe battery management systems (BMS) to address the needs of battery electric multiple unit (BEMU) trains, freight train locomotives and other specialized railway maintenance equipment.

On display in Leclanché’s InnoTrans stand 260 in Hall 11.1, the company will be showing its railway specific INT-53 Energy Battery Pack. The fully modular and scalable system is configurable for a large range of railway energy requirements. It includes liquid-cooling in every pack and provides real-time access to battery status, performance, and diagnostic data via a comprehensive user interface.

The INT-53 Energy Battery Pack resides in a robust aluminum enclosure that is IP65 rated. The fully self-supported high strength pack structure can be optionally end-mounted if required. The system features standard CAN bus communication for system connectivity. It is expandable by integrating multiple packs using a multistring controller.

Subsystems comprising up to eight packs in parallel, making a total of 424 kWh, can be combined to further increase capacity as required. For G/NMC batteries, it provides an industry leading cycle-life of 8,000 cycles at 80% DoD and 4,500 cycles at 100% DoD.

Leclanché’s battery systems are designed to meet the railway industry’s most rigorous safety standards including EN45455, IEC62619 and EN50128 and the company is IRIS / ISO TS 22163 certified. The company’s proprietary battery management system, developed by its in-house team of hardware and software engineers, is designed in accordance with SIL 2 level requirements.
