Optimizing thermal management of electrified vehicles for an overall improved performance

Overcome electric vehicle thermal management challenges using simulation

Estimated Watching Time: 37 minutes


Vehicle electrification design requires a strong focus of car manufacturers on thermal aspects to improve vehicle performance for safety, driving range, passenger comfort, and battery life span.

A critical challenge is to study the energy efficiency of the overall electric vehicle, while the various design choices include a large variety of parameters. For instance, OEM engineering departments must consider climate conditions and dependency on the different vehicle subsystems under real driving conditions.

In this webinar, Eric De Hesselle will present how Simcenter solutions can support the creation and utilization of your Digital Twin electric vehicle. He will show how using the example of a complete digital twin of a Siemens e-vehicle – from component design to overall electric system integration – you can use simulation tools to analyze thermal management and energy efficiency. Sana Loussaief will detail how Simcenter system simulation helps get results over the EPA 5-Cycles thanks to a fully designed electric vehicle model.

Optimizing the digital twin of your electric car to improve overall energy efficiency

Developing the digital twin of your electric vehicle with Simcenter allows you to understand how design choices impact the vehicle's overall system thermal management. The challenge for engineering while accelerating the vehicle design and development process is to get to know how to retain the right level of high-fidelity results while leveraging fast simulation speed? It naturally starts with basic requirements for range and performance. Before analyzing component and vehicle thermal management, it quickly turns into powertrain sizing with higher fidelity models for e-motors, HV Batteries, and IC Engines.

Running electric vehicle system simulation over EPA 5-Cycle procedure

An electric vehicle system modeling includes the vehicle powertrain, the electric circuits, and the different subsystems cooling loops. Using Simcenter Amesim software enables system engineers to develop the vehicle architecture early in the design process, including the battery, the power electronics and e-motor thermal management systems, and HVAC and cabin systems. To some extent, the system simulation enables to get results over the EPA 5-Cycles procedure and understand the impact of driving cycles and climate on energy consumption and driving range.
