Ripple and Electromagnetic Fields in Electric vehicles (RIFEL)
Purpose and goal
The purpose of RIFEL has been to develop the necessary knowledge in the modeling theory together with the academy in order to fulfill the objective. The goal was to design a verified system model consisting of HV components from an electric drive line that can simulate voltage and current ripple in a frequency range up to 100kHz. The result was a system model that can handle this but most models can handle frequencies up to 1MHz, which may be considered very satisfactory.
Expected results and effects
The outcome of RIFEL, and the system model that was developed, will result in earlier verification of changes in existing products as well as easier development of models for future projects. Some proactive work remains before supplier models can be used in the system model, but this iterative work is in progress. Currently, the system model will save time during verification work, but earlier verification in upcoming projects will also give significant benefits.
Planned approach and implementation
The project included five work packages, where three of these represented component-level modelling. These models were then used in another work package and merged into a system model whereas the last work package led project management and administration. All modeling work packages also had verification and documentation responsibility for their models, but also knowledge-sharing activities in the form of seminar presentations and publications at conferences. During the last part of the project, several project members came to work in several of the work packages.
