BEV 產品開發:要使 BEV 開發週期與傳統動力車輛專案的計畫時間表保持一致,就需要更改工程團隊的結構和工具集。魔哦你驅動設計流程可以減少重新設計和物理原型製造,加快從概念到設計的進度,以解決這種特殊挑戰。Altair® e-Motor Director™ 是單一的工作環境,專家可以在其中提供儲存為解決方案的最佳實踐方法,使用者可以將其拖放並連接到更複雜的工作流程中,準備好自動執行。
在計畫實施前的均衡設計期間考慮輕量化:重量減輕對於提高電池續航能力和電力推進性能非常重要。 Altair Concept 1-2-3 設計流程使設計人員能夠透過模擬瞭解車輛架構、製造流程、材料選擇和平臺策略,以自信地創建和評估新一代創新架構。
執行設計研究,做出明智的電機選擇:在概念階段快速執行設計研究及可行性排序,根據結果做出明智的最佳下游電力推進決策。Altair® FluxMotor® 可以用來進行性能比較,選出最佳的電機拓撲結構,同時考慮效率、溫度、重量、緊湊性和成本等限制條件。
提高能源效率
車輛續航能力強:汽車越輕,加速和維持速度所需的電池電量越少,使單次充電的行駛距離更長。生成式設計賦予工程師在保持安全和舒適所需的強度和剛度特性情況下減少使用材料的能力。由於所需的功率較小,電池組的大小和重量因而減小,而電池組的尺寸和重量正是影響電動汽車重量的主要因素之一。
效率、冷卻和雜訊的詳細設計:要想在效能、成本和重量之間達到平衡,設計人員可以通過多物理場模擬,以提高電動汽車的駕駛體驗。使用 Altair® Flux® 執行詳細的電機電磁仿真,並使用 Altair CFD™ 執行磁熱模擬,可評估對流和輻射對效率損失的影響。借助 Altair® OptiStruct®,可以了解電力推進系統對聲音品質和乘客體驗的影響,並可使用 Altair CFD 瞭解風噪和路噪。
電動汽車面臨的碰撞和安全挑戰:電池組對於電動汽車的安全至關重要,因此需要從車輛碰撞事故和道路碎片碰撞與衝擊的模擬深入洞察,以與車輛計畫進展的速度保持一致。Altair 在車輛安全方面進行了大力投資,並與車輛電池研究領域的領先企業合作,目前已能夠高效而準確地分析可能會因短路而導致電池起火的機械故障。
設計未來的電動汽車
EV 性能優化:EV 子系統對周圍系統的影響很大,可以借此優化車輛性能。透過多學科方法,設計人員可以分析和優化複雜系統中的關鍵性能屬性,實現最終設計平衡。
驅動和控制整合:Altair 基於模型的開發解決方案藉由模擬模型來加速設計交付,同時支持不同等級機電一體化系統的複雜性。可以在電機、功率轉換器和控制策略設計中部署不同等級的模型保真度 (從 0D 到 3D),以與車輛開發階段相配合。1D 和 3D 模擬研究可以依序或同時耦合,透過代表性系統模型評估產品性能,所有這些都是為了提高設計效率。
V2X、ADAS 和無人駕駛汽車:電動汽車解決方案必須與周圍系統建立連接並進行交互作用,並且不能干擾車載電氣系統 (EMC/EMI)。Altair® Feko® 高頻電磁學軟體和波傳播工具能夠幫助車輛設計人員執行虛擬駕駛測試,並將使用專用短程通信 (DSRC) 或 5G 無線信號的環境障礙納入考量。

Guide to Using Altair RapidMiner to Estimate and Visualize Electric Vehicle Adoption
Data drives vital elements of our society, and the ability to capture, interpret, and leverage critical data is one of Altair's core differentiators. While Altair's data analytics tools are applied to complex problems involving manufacturing efficiency, product design, process automation, and securities trading, they're also useful in a variety of more common business intelligence applications, too.

An Altair team undertook a project utilizing Altair® Knowledge Studio® machine learning (ML) software and Altair® Panopticon™ data visualization tools to investigate a newsworthy topic of interest today: the adoption level of electric vehicles, including both BEVs and PHEVs, in the United States at the county level.
This guide explains the team's findings and the process they used to arrive at their conclusions.
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. It combines innovative design methods and tools to model and predict mechanical damage phenomena as well as thermal and electro-chemical runaway. Altair has developed an efficient way to calculate mechanical and short-term thermal response to mechanical abuses, providing accurate computational models and engineer-friendly methods to design a better battery.
