6 use cases for CAE simulation in electric vehicle drivetrains

While a lot of attention is focused on battery performance, the electric drivetrain presents completely new engineering challenges that require extensive simulation to understand how interconnecting systems affect each other.

01

NVH

With combustion noise gone, passengers notice outside noise, gearbox and coolant sounds. Simulation shows how disparate parts contribute to NVH so issues are remedied in design.

02

Electric motor performance

Multiphysics simulation helps optimize motor efficiency together with gear ratios for highway and uphill performance.

03

Thermal management

EV thermal systems are more complex than ICE. Simulation models the whole vehicle to integrate motors, inverters, generators and batteries efficiently.

04

Lubrication

EV motors run at very high speed and still need oil and coolant. CFD simulation helps engineers choose the right lubricants for their designs.

05

New materials

Reducing weight improves efficiency and responsiveness. CAE simulation shows how new lightweight alloys behave in driveline components.

06

Durability

Run fatigue tests and predict failure conditions for every EV driveline component, informing repair schedules and warranties.

CAE Value supports OEMs and suppliers in two ways: as value-added resellers of VI-grade simulation apps and driving simulators, Siemens Simcenter HEEDS and Amesim, SES-AgileTire™ and our own ParaMount bushing tool — including custom workflow setup; and as CAE consultants bringing multidisciplinary expertise, performing simulations for clients without CAE staff and expanding capacity during peak production.

Real-time testing

Why choose Concurrent Real-Time for HIL & SIL testing

A real-time test environment only pays off when it behaves like the system you are building — every millisecond of jitter is a result you cannot trust. Here is what teams developing mission-critical vehicle, defence, aerospace and energy systems get from building their HIL and SIL rigs on Concurrent Real-Time.

01

Deterministic timing

RedHawk Linux delivers hard-real-time determinism with sub-microsecond latency, so a HIL loop reacts exactly when the model says it should — no jitter, no re-runs, no results you have to question.

02

The model you develop with

Simulation Workbench runs your own C code or third-party models from MATLAB, Simulink and Adams directly on the real-time target, so the model you design with is the model you test with.

03

Scale from desktop to rack

Start as SIL on a workstation and move the identical setup onto iHawk hardware in the lab — the platform scales with your test scope instead of forcing a rewrite.

04

I/O that matches the unit under test

Rugged modular I/O, high-speed data acquisition and synchronized capture let you close the loop against real ECUs, sensors and actuators, and record every channel on the same clock.

05

More tests in parallel

RedHawk KVM-RT virtualization runs several real-time guests and models on one machine, multiplying coverage and regression runs without multiplying hardware or lab space.

06

Open standards, no lock-in

RedHawk adheres to open standards, so your test environment integrates with existing open systems architectures and stays yours as programmes, suppliers and teams change.

CAE Value helps you put Concurrent Real-Time hardware, RedHawk Linux and Simulation Workbench to work in your own HIL and SIL environments — from the first real-time target to a fully automated test rig — with the same engineers setting it up and supporting it.
