Leveraging Multiphysics Simulation for Enhanced Battery and Cabin Cooling Design

Leveraging Multiphysics simulation for enhanced battery and cabin cooling design, the development and optimization of electric vehicles (EVs) confront a significant challenge: harmonizing passenger comfort, EV range, and battery cost. Ensuring a top-tier passenger experience can sometimes reduce EV range – by as much as 40% under extreme weather conditions. Under milder weather conditions, heating or cooling services lead to an energy increase of up to 15% per mile. Yet, designers are working relentlessly to reduce this trade-off using innovative approaches such as the integrated design and verification process. 

The Role of an Integrated Design and Verification Process 

The integrated design and verification process has emerged as a key tool in reducing the energy consumption-versus-comfort trade-off. This comprehensive technique involves meticulously choosing materials, window treatments, operating strategies, and designing localized heating and cooling solutions. The process aims to offer a prime passenger experience while simultaneously upholding temperatures suitable for onboard electronics. It also ensures battery temperature is kept within a peak efficiency range, thereby satisfying regulatory requirements, and extending both the range and battery lifespan. 

The Evolution of Passenger Expectations and its Impact on Design 

With the expansion of the electric vehicle market, customer expectations have skyrocketed. Amenities previously deemed extra or optional have now become a differentiator, setting brands apart. For instance, the vehicle cabin’s climate system plays a significant role in shaping the passenger experience, making Heating, Ventilation, and Air Conditioning (HVAC) systems crucial components. Holistic solutions for HVAC design are thus required to provide an optimal passenger experience without sacrificing the vehicle’s range. 

Battery Thermal Management: The Heart of Electric Vehicle Design 

In the grand scheme of EV design, battery thermal management is a critical factor. While high temperatures can increase battery efficiency, prolonged exposure to these conditions can lead to premature degradation. Hence, maintaining optimal battery temperatures is a necessity to ensure peak efficiency and prevent adverse impacts on durability.

This results in highly accurate end-of-life performance predictions for the battery. 

The Interplay of Electric Vehicle Cabin and Battery Cooling 

Designing an efficient vehicle involves dealing with complex interactions between various elements. Any alteration in cabin temperature or occupant comfort can influence the HVAC system, battery cooling, and overall vehicle efficiency. Therefore, these systems must be designed and optimized holistically, considering both the performance of individual components and the overall system. Dassault Systèmes offers toolkits that enable easy integration between models in different subsystems with varying physics, allowing engineers to concentrate on optimizing overall vehicle performance.
