EnginSoft and Metasystem develop design validation, verification methodology for highperformance on-board chargers for electric vehicles

Abstract

On-board chargers (OBC) are one of the key components in the energy efficiency of electric vehicles.

They must meet various requirements relating to mechanics and to electro-mechanical integration. Tolerances are fundamental in meeting these requirements. However, the small dimensions and the amplifying effects typical of the propagation of tolerances require additional compliance verification steps.

This article describes how EnginSoft supported Metasystem in acquiring the know-how to satisfy future customer requests on the one hand, and to create projects that are as profitable as possible in terms of waste minimization, on the other hand.

CASE STUDY

Model-based characteristics: the missing link in dimensional management

Dimensional management in modern manufacturing demands more than just accurate geometric tolerances—it requires data consistency, traceability, and automation across the entire product lifecycle. Traditional practices like annotated PDFs and Excel-based inspection plans introduce risk and inefficiency by detaching product and manufacturing information (PMI) from the 3D model. Siemens’ NX Inspector addresses this challenge through the introduction of Model-Based Characteristics (MBC)—standards-compliant, machine-readable data objects that convert each PMI requirement into a uniquely identified, traceable element within the CAD environment.
