NGHVT Next Generation High Voltage Topology
Purpose and goal
The aim of the project is to enable a generation , commercialization and platform alignment of the components connected to the hybrid cars´ high voltage grids , with the exception of the battery system - focusing on drive systems , charging systems and the DC bus itself . Overall goal is to , with a view to 2017 , reduce högspänningskomponenters total cost, weight and volume by 25%. Additionally, expected system efficiency is improved by five percent , thereby enabling a CO2 reduction of 12% on fleet basis.
Expected results and effects
Increased client expertise through model-based development and supplier development. Synergies through intensified cooperation with selected suppliers as well as with experts in the western Swedish competence cluster. Upgraded specifications and ordering data for high-voltage components with focus on drive systems and charging systems . Improved and standardized simulation models of battery systems with regard to the problem parameters such as accuracy , temperature and charging status.
Planned approach and implementation
Main activities of the project are : Literature study and inventory of simulation models. Evaluation and development of suppliers of components and systems . Development and integration of simulation models for high-voltage power systems and nätladdningssystem that fits together with the adjacent simulation project . Ensure that the new guidelines for the development of high-voltage systems fit VCG ´s all car sizes and types.
