Efficient E-mobility through Simulation

In order to produce electric cars for the mass market still various requirements place themselves in different disciplines against the production development.
The performance, durability and functional safety of the battery, which serves as an energy supplier or memory, is thereby one of the most important success criteria. But the questions about the optimal use of materials, vehicle dynamics, the synchronization of components for intelligent energy consumption and optimization of the charging of "Electric stations" by cable or by inductive energy transfer are not yet finally resolved. A further goal is to be able to provide the description of an intelligent consumer-oriented energy management (Smart Grid).
With numerical calculations, the various electro-mechanical, physical and electrochemical processes can be analyzed and optimized in order to intervene at an early stage in the further product development. By means of simulation the interaction of all components can be illustrated and so an efficient electric car be developed.
CADFEM has been working for over 25 years with the numerical simulation and the approaches and simulation solutions for e-Mobility are presented below:
CADFEM Solution for Li-ION Cells
Description of the electro-thermal processes within a cell by taking into account the thermal interactions.
The goal is to find a cell structure that ensures the reliability of the electrochemical process with respect to the control. A high load capacity and speed of the charging process are further assumptions.
The CADFEM approach allows the description of the charging and discharging of a battery cell using a physical model with the ANSYS Simplorer system simulator.

CADFEM Solution für Battery (Cell Structure)
Description of the interaction of individual cells in cell assembly.
A goal is to be found for the suitable arrangement and linkage of individual cells in order to achieve as high a life span in a given thermal instrument range as possible.
CADFEM links the physical compact models of individual cells with the numeric description of thermal boundary conditions (FEM + MOR) in the overall system.
The peculiarity of this system description is based on the proper integration of reduced models that are derived from detailed FEM models.
CADFEM Solution for Battery Cooling
Description of the thermal management of a battery under operating conditions.
The goal is the design of a suitable cooling system of the battery for the supply of electricity for the connected components. The consideration of real operating conditions (driving, load cycles) is of special importance in this connection during the Design phase.
The available ANSYS solutions to describe the cell and the cell group allow the system simulator Simplorer for the illustration of real time near load scenarios.

CADFEM Solution for Electrical Drives
Description of the drive train consisting of: control, power electronics, electric motor and mechanical components..
Aim is to design an energy-efficient drive train in the chain of acting elements for each application. By using simulation one can incorporate new engine concepts at an early stage through detailed numerical descriptions of the development process.
The CADFEM solution plans the integration of order-reduced models, e.g. for the electric motor, sensors and for mechanical components. The simulation of the entire system including control and power electronics is performed using ANSYS Simplorer system simulator.
The details of the individual components can also be mapped in a 2D or 3D FEM simulation and optimized. This detailed analysis is done for the magnetic components with the ANSYS tool Maxwell, for the mechanical by means of ANSYS Mechanical.

CADFEM Solution for Light-Weight Construction
Description of new design principles to reduce overall weight by use of alternative materials.
The aim is to reduce the overall weight, increasing the service life and ensuring the safety of support structures. The use of lightweight construction principles makes it possible in electric cars not only to compensate the excess weight of the battery, but also to lower energy consumption and to ensure security and life span.
The CADFEM solution enables the exact mapping of composite and composite materials in the simulation.

- For the description of alternative materials, different software solutions are used
CADFEM Solution for Vehicle Dynamics
Description of the driving behavior of electric vehicles.
The goal is to tune the components of the electric vehicle for intelligent energy consumption optimization.
The knowledge and the integration of all components allows a detailed forecast of consumption and adaptive control of the driving behavior. The ANSYS solution links all behavioral models and enables the design of an optimal control of the overall vehicle system behavior with the ANSYS simulator Simplorer.

The CADFEM solution contains comprehensive tools for the electromechanical description of plug connectors and inlets "Electrical gas-station" (ANSYS Mechanical). Established numerical field calculation methods allow the detailed analysis of inductive charging process with the ANSYS tools Maxwell Q3D and Simplorer.
CADFEM Solution for Smart Grid
Description of an intelligent consumer-oriented energy management of electricalmobile applications.
The aim is to develop an intelligent power supply system (Smart Grid) for the supply of distributed power by taking into account consumer demand fluctuations.
The system simulator Simplorer enables near real-time description of the energy supply network of the production, storage, distribution to the consumer. The specialty of the CADFEM solution is based on the integration of order-reduced models, which are derived from detailed FEM models.
