Electric vehicles are ushering in a new era of travel that is efficient, affordable, clean and green. They will transform travel in the years to come and shape the future of mobility connected with smart cities, and interactive communities. Bringing this new generation of cars onto the road requires new vehicle innovators, OEM leaders and suppliers alike to rethink the way vehicles are engineered. To meet the demand now, this needs to happen quickly.
Compressed development cycles require vehicle manufacturers and their partners to work in sync like never before. With multiple systems in the vehicle being affected, the integration of new technologies is a significant engineering challenge. This, calls for a new solution that will better connect disciplines to help engineers look at vehicle performance in a new, more holistic way.
Designing Wireless Systems for Autonomous Vehicles Using Simulation
Interview with Joy Laskar, CEO from Maja Systems, explaining how simulation augments the development of wireless systems.
Batteries are the new fuel tanks in electric vehicles. They need to store as much energy as possible to minimize range anxiety, as well as maintain safety in case of unexpected events. Batteries are highly complex systems, requiring advanced engineering methods at all levels: from chemistry to cell engineering, to module and pack engineering, and finally integration into full vehicles.
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.
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 the challenges in the design of a three-phase inverter power module, in particular the thermal management, EMC compliance, and parasitic extraction aspects.
