Partners

With our partners, we can carry out both the research‑intensive development of new simulation models and their validation in a timely manner.

DIN/VDA and ZVEI

Based on the documents of the DIN Committee on Automotive and Mobility and the German Electrical and Electronic Manufacturers’ Association (ZVEI), to whose development PSS makes a significant contribution, PSS develops models for a standardized, cross‑company description and simulation of electrical components using thermal networks.

What we provide:

  • Standardized modeling approaches for electrical components (e.g., cables, contact and connector systems) based on thermal network models,
  • Software tools that calculate and export the required input parameters, enabling users to create equivalent circuits and populate them with correct values.

An initial approach to modeling thermal networks for the simulation of electrical components is described in the ZVEI Working Group “Thermal Simulation” guideline. More binding and detailed specifications will be found in the DIN/TS 70101 “Thermal simulation models for vehicle electrical systems”, which is currently in development.

PSS is continuously enhancing its software tools with the goal of achieving direct compatibility with the applications and input formats of this forthcoming standard. In particular, the K‑module is intended to enable a modular and standards‑compliant simulation in the future.

Bayern Innovativ

PSS contributes to the development of a standardized methodology for assessing the aging behavior of electrical components in the on‑board power network at Bayern Innovativ.

Based on specified thermal, electrical, and mechanical load profiles, we develop models and forecasts for:

  • failure times (time‑to‑failure) and failure rates (FIT),
  • dominant aging mechanisms and sensitivities,
  • risk classes as well as recommendations for design and validation.

The goal is a robust and comparable decision‑making basis for development, production release, and lifetime estimation.

Universität der Bundeswehr München

In collaboration with the Institute for Mathematics and Computer-Based Simulation and the Institute for Applied Mathematics and Scientific Computing at the Universität der Bundeswehr München, PSS addresses demanding challenges at the interface of mathematics, simulation, and engineering.

BSFZ

The project “FTMA: Fast Thermal Analysis for Electric Components” is funded with the support of the Certification Body for the Research Allowance (BSFZ). The goal is rapid simulation of generalized structures of thermal RC networks (e.g., cable harnesses with contact/connector systems and loads), independent of circuit topology or geometry.

  • Project focus: Accelerated thermal simulation of RC networks
  • Application examples: Cable harnesses, contact/connector systems, loads
  • Funding framework: Research Allowance (BSFZ)
