HIFI-ELEMENTS will develop, validate and publish a recommendation for standardisation of model interfaces for common e-drive components, and will implement compliant versions of existing models. The project will implement a seamless workflow linking extended versions of existing tools, a model/data management tool and a co-simulation tool for MiL and HiL environments, augmented with effort-saving automated methods for model parameterisation and test case generation. Validation of standardised models and workflow will be done in four industry-relevant use cases depicting common scenarios in e-drivetrain and EV development. On project conclusion, the interface recommendations and workflow methods will be disseminated in order to gain widespread EV-industry adoption.
HIFI-ELEMENTS seeks to implement and investigate a streamlined workflow that makes the use of diverse modelling and simulation tools more efficient. A workflow that is conducive to model reuse promotes consistency between different models of the same physical component and requires the developers working in the early concept stages to consider the evolution of their models as their design matures.
Coupled with this workflow will be a proposed standardisation of functional model interfaces. Existing standards such as FMI focus on the formulation of a formal interface format description under the assumption that the physical signals, data rates and data types have been defined. The proposed functional model interface standard—defining model boundaries, signals and data particulars—will add a crucial element towards consistency and seamless use of models in the development process.
Additionally, we will explore the integration of methods for automatic parameter identification and for the generation of test cases into this workflow as both model parametrisation/calibration and test management require high efforts when faced with a fragmented population of models.
Within HIFI-ELEMENTS, we are proposing solutions that can overcome some remaining limitations: we do not seek to invent or pioneer new tools but instead to showcase how fragmentation can be reduced and existing tools can be used more efficiently. We will build on existing standards and initiatives to improve scalability, modularity and real-time use of simulations for system characterisation, optimisation and validation and thus enable faster introduction of novel e-drive technologies to the market.
