Sustainable design solutions to meet next-gen vehicle demands.

Integrated system-level, multi-disciplinary and multiphysics solutions offer designers the ability to understand and optimize the complex, connected architectures of today’s battery-electric vehicles (BEVs).

Scaling e-Mobility from niche to mass-market.

As OEMs begin to create BEV for their mainstream customers to address issues like range, drivetrain efficiency and charging times, design becomes an even more vital component of the development process. This requires fast exploration of higher system voltages, innovative cooling implementations and the ongoing race to reduce vehicle weight.

Accelerate Product Development

BEV product development: Aligning BEV development cycles with traditional powertrain vehicle program timelines requires changes to engineering team structures and toolsets. To address unique challenges, simulation-driven design processes help advance concepts to the design stage with fewer redesigns and physical prototypes. Altair® e-Motor Director™ is a single working environment where specialists can provide best-practice stored as solutions which users can drop and connect into more complex workflows, ready to be executed automatically.

Lightweighting during pre-program for balanced design: Mass reduction is a key contributor to the battery range and e-propulsion performance. The Altair Concept 1-2-3 design process enables designers to confidently create and assess innovative next generation architectures by using simulation to inform vehicle architecture, manufacturing processes, material selection, and platform strategies.

Design exploration for informed e-motor selection: Use rapid design exploration and feasibility ranking during concept phase to inform optimal downstream e-propulsion decisions. Altair® FluxMotor® can be used to make performance comparisons to select the best e-motor topologies, considering constraints like efficiency, temperature, weight, compactness, and cost.

Enhance Energy Efficiency

Wide-ranging vehicle range: Lighter cars require less battery power for accelerating and maintaining speed, allowing a single charge to go further. Generative design enables engineers to remove material, while maintaining strength and stiffness properties required for safety and comfort. With less power required, the battery pack size and weight is reduced, one of the biggest contributors to an electric car’s weight.

Detailed design for efficiency, cooling and noise: To balance performance, cost and weight requirements, designers can utilize multiphysics simulation to enhance the e-Mobility driving experience. Detailed e-motor electromagnetics with Altair® Flux® and magneto-thermal simulation with Altair CFD™ evaluates the convection and radiation contributing to efficiency losses. Altair® OptiStruct®offers insight into sound quality and passenger experience influenced by e-propulsion systems, as well as wind and road noise with Altair CFD.

e-Mobility challenges in crash and safety: The battery pack is critical in e-Mobility safety, and insights from the simulation of vehicle crash events, road debris impact and shocks need to align with the speed of your vehicle program. Altair’s investment in vehicle safety, in collaboration with leaders in vehicle battery research, now enables efficient and accurate analysis of mechanical failures that could lead to battery fires because of a short circuit.

Designing the Future of e-Mobility

EV performance optimization: EV subsystems have considerable influence on surrounding systems, providing opportunities to optimize vehicle performance. Using a multi-disciplinary approach, designers can analyze and optimize key performance attributes across complex systems to find a balanced final design.

Drive and control integration: Altair’s model-based development solutions leverage simulation models to accelerate design delivery, while supporting different levels of mechatronic system complexity. Varying levels of model fidelity (from 0D to 3D) can be deployed in electric machine, power converter and control strategy design to match the vehicle development phase. 1D and 3D simulation studies can be coupled, sequentially or simultaneously to evaluate product performance through representative system models, all built to enhance design efficiency.

V2X, ADAS and autonomous vehicles: e-Mobility solutions must connect and interact with their surroundings without interfering with in-vehicle electrical systems (EMC/EMI). Altair® Feko® high-frequency electromagnetics software and wave propagation tools help vehicle designers perform virtual drive testing, and consider a full array of environmental obstacles using either Dedicated Short Range Communications (DSRC) or 5G wireless signals.

E-motor Design using Multiphysics Optimization

Today, an e-motor cannot be developed just by looking at the motor as an isolated unit; tight requirements concerning the integration into both the complete electric or hybrid drivetrain system and perceived quality must be met. Multi-disciplinary and multiphysics optimization methodologies make it possible to design an e-motor for multiple, completely different design requirements simultaneously, thus avoiding a serial development strategy, where a larger number of design iterations are necessary to fulfill all requirements and unfavorable design compromises need to be accepted.

The project described in this paper is focused on multiphysics design of an e-motor for Porsche AG. Altair’s simulation-driven approach supports the development of e-motors using a series of optimization intensive phases building on each other. This technical paper offers insights on how the advanced drivetrain development team at Porsche AG, together with Altair, has approached the challenge of improving the total design balance in e-motor development.

Using Multiphysics to Predict and Prevent EV Battery Fire

Electric vehicles (EV) offer the exciting possibility to meet the world’s transportation demands in an environmentally sustainable way. Mass adoption could help reduce our reliance on fossil fuels, but the lithium-ion (Li-on) batteries that power them still present unique challenges to designers and engineers, primary among them to ensuring safety against battery fire. To achieve vehicle manufacturer’s ambitious adoption goals, it is necessary to improve the safety of Li-on batteries by better understanding all of the complex, interconnected aspects of their behavior across both normal and extreme duty cycles. Altair is focused on developing a comprehensive understanding of automotive battery safety issues which it has named the Altair Battery Designer project.
