Battery technology

Vehicle batteries, power supply systems, condition/durability, energy balance, etc.

We can assist you with your battery and charging systems, including outside the railway sector, to ensure that your stationary facilities and vehicles operate reliably.

We offer rail companies, repair and maintenance facilities as well as vehicle manufacturers solid engineering services in the field of electrical propulsion technology – independently and in line with your requirements:

  • For servicing your rail vehicles: Our comprehensive knowledge and holistic approach to vehicles help to avoid vehicle downtime and expensive consequential damage. By evaluating data and leveraging our many years of experience, we can identify components that require attention and develop appropriate alternatives.
  • For accompanying and consulting during the procurement process: By specifically defining and accurately describing projects, component properties and services, we will work together with you to create effective concepts and realistic requirements. We can therefore safeguard the implementation of these concepts and requirements when carrying out design reviews, tests and acceptance activities.
  • With tests, damage analyses and expert assessments: In the event of a damage incident, we examine the affected assemblies, clarify failure causes and devise rectification measures for you to avoid future assembly downtime and damage.

We coordinate potential areas of economical and technical improvement and assist you in implementation.

  • When it comes to the energy consumption of the fleet: Our solid, well-established know-how in electrical subsystems on board railway vehicles allows us to identify targeted areas in which energy savings can be realised (e.g. by monitoring consumption) and help you achieve these savings. In some cases, a great deal of energy can be saved simply by implementing basic operative measures.
  • When it comes to qualifying suppliers: Different objectives must be coordinated to avoid delivery bottlenecks and costly inventory levels. We can help you select suitable suppliers, define cost-effective procedural approaches, carry out quality assurance checks and accept contracted work and deliveries.
  • When it comes to maintaining, repairing and modernising: We can leverage the many decades of expert knowledge we have acquired in catering to a wide range of vehicle types employing various different electrotechnical technologies. This, in turn, allows us to answer all of your questions, define and draft maintenance guidelines and coordinate individual measures (such as whether a particular energy-savings strategy really is beneficial).

Our fields of expertise:

  • Vehicle batteries (battery systems)
  • Installation and ventilation of the battery housing
  • Power supply (e.g. in stationary facilities such as signal boxes)
  • Emergency power supply
  • On-board electrical system power supply
  • Battery components
  • Electronic components
  • Testing/analysis of batteries with respect to condition and durability
  • Analysis of energy balance in vehicles

We can also offer you the services of an expert/appraiser who is formally recognised by the German Federal Railway Authority (EBA) in the design of battery systems that require active monitoring in accordance with paragraph 33 of the German Railway Construction and Operating Regulations (EBA).
