SIMULATION FOR ELECTRIC VEHICLES
Steering the Digital Future of Electric, Connected and Autonomous Vehicles
Driverless, connected cars are ushering in a new era of travel that is efficient, affordable, clean and green. Experts predict these systems will transform travel in the years to come and shape the future of mobility, smart cities, and interactive communities. Bringing this new generation of cars onto the road requires new vehicle innovators and OEM leaders alike to rethink the way we experience their products, and the way they engineer them.
The unique challenge posed by the integration of new technologies (including LiDAR and other advanced sensing devices, batteries, new broadband antennas, electric drives and power electronics), along with the need to improve efficiency, calls for new solutions and applications that will better integrate engineering disciplines to help engineers look at vehicle performance in a new, more holistic way.
Dassault Systèmes with its family of brands is tackling this very challenge with solutions and key technologies to design, evaluate and optimize EV in an interconnected, multidiscipline framework.
The battery of an electric vehicle is a highly complex system involving multiple and connected physics. CATIA, BIOVIA and SIMULIA are working together to bring a solution that truly connects mechanical and system design, materials and chemistry modeling, and performance assessment of battery cells, modules and packs.
This 30-minute Webinar provides an overview of solutions for digital battery engineering and dives into specific applications on topics such as coupled thermal-electric-displacement analysis, SOC(State of Charge)-induced expansion, ultrasonic welding analysis, and general structural analysis.

The electric drive is a much more complex system to design than it might appear to be. To meet design requirements, teams need an environment which will allow them to optimize designs by simultaneously taking into account noise and vibrations, thermal management of the heat dissipated by high rotation speeds and electromagnetics losses, proper lubrication of the integrated gearbox, etc.
This presents a challenge to electric vehicle designers and manufacturers, as EVs have their own unique challenges that don’t affect traditional automobiles. One of those challenges is that of noise. Electric vehicles are known for being quieter than traditional cars, but the lack of sound from an engine means that other noises and vibrations are much more apparent.

The main purpose of a power electronic system in an electric vehicle is to manage the transfer and conversion of electrical energy between the battery and various components of the vehicle such as an electric drive, on-board electronics, external charging system (plugin or wireless). Some of the main challenges to be addressed include thermal management and electromagnetic compliance.
This 30-minute webinar provides an overview of simulation solutions that address these challenges in the design of a three-phase inverter power module. In particular, it addresses the thermal management, EMC compliance, and parasitic extraction aspects.
Electric vehicles rely almost entirely on the battery alone to provide the energy to warm or cool the cabin and make occupants comfortable. Simulation-driven design for climate systems can help diagnose and prevent energy loss: improving HVAC system efficiency and boosting battery life and vehicle range.
