AVL Focus - Issue 2025

VL’s new AVL Tilting Powertrain TS™ redefines pow-

ertrain testing by combining road gradient, driving

resistance, and ambient temperature simulation in a

single unit. At its core is an innovative dynamic tilting platform

that simulates gradients and lateral inclinations, enabling

uphill, downhill, and cornering maneuvers without ever leaving

the test hall.

Designed for passenger cars through to heavy-duty trucks,

it enables tilt angles of up to ±45° around two axes and tilt

speeds of up to 15°/s. Wheel load units provide peak torques

of up to 7,000 Nm for light-duty vehicles and up to 40,000

Nm for heavy-duty applications. An optional climate chamber

allows testing from -40 °C to +80 °C.

This unique setup multiplies testing options, ensures valid

results, and boosts efficiency by avoiding costly development

loops. By shifting validation to earlier phases, the AVL Tilting

Powertrain TS™ accelerates time to market, reduces costs,

and raises product quality.

New AVL Tilting Powertrain TS™ Is Expanding

the Limits of E-Powertrain Testing

old weather is one of the toughest realities for electric

driving. Tests show range losses of up to 30 % in sub-

zero conditions. The reason lies in physics: BEV power-

trains produce little waste heat, yet batteries, power electron-

ics, and the cabin must all be kept within narrow temperature

limits. Their needs often conflict: batteries require heating in

the cold, electronics demand cooling under load, and passen-

gers expect comfort at all times. As a result, up to one third

of the vehicle’s energy is consumed by thermal conditioning,

making efficient control strategies essential.

AVL ThermalLab™ addresses these challenges by enabling ac-

curate analysis and optimization of vehicle thermal manage-

ment systems without complete prototypes. Real components

– pumps, valves, heat exchangers, cabin heaters – are tested

Is Tackling the Thermal Challenge in BEVs

under realistic conditions. The lab simulates component

temperatures from −25 °C to +90 °C, transient load cycles,

rapid temperature changes, and control function integration.

Entire cooling circuits can be validated in an emulated vehicle

environment for repeatable, efficient testing, where climatic

chambers supply temperatures in the range of −40 °C to

+60 °C and controlled humidity.

Combining physical testing with multiphysics simulation and

virtual calibration lets OEMs validate concepts earlier, reduce

late changes, and cut prototype effort. The benefits are

measurable: lower heating and cooling demand, more winter

range, improved battery durability, fewer warranty claims,

shorter time to market, and progress toward sustainability

targets.
