Using Hybridization between the Partial Element Equivalent Circuit Method and the Multi-Conductor Transmission Line Method to Improve EMC in Rear Batteries 2008-01-1475
The increasing complexity and amount of equipment under the hood has led car manufacturers to place the battery in the trunk. Consequently the connections between the battery and the engine will require large cable bundles when the potentially disturbing frequencies flowing on the cables range from DC to several hundred kilohertz. In this paper, we address the implementation of a simulation tool which enables us to assess the effect of those connections. This tool aims at rapidly obtaining a circuit equivalent for the bundle and is based on the PEEC method (Partial Element Equivalent Circuit) as well as on the MTL method (Multi-conductor Transmission Line). The PEEC method gives us inductances when the MTL method provides us with the values of the capacitors which the model uses. The electric model obtained in that way makes it possible to connect this virtual bundle to battery and alternator models in order to understand the resonance phenomena created by this interconnection.
