AVL Focus - Issue 2025

he growing diversity of powertrain concepts increas-

es the demand for precise and realistic testing.

­Accurate simulation of real-world conditions requires

high-performance media conditioning systems. The new AVL

­ConsysActive portfolio provides this capability with efficient

refrigeration circuit control, ensuring precise and energy-effi-

cient testing conditions. The modular product family includes

air, glycol, and oil conditioning units that deliver stable and

reproducible results under steady-state operation.

or a decade, AVL E-STORAGE BTE™ has set the

benchmark in battery pack testing and emulation.

As AVL’s first in-house electrified product line, it

established scalable, precise energy supply solutions for

e-mobility. Today, more than 1,500 channels are installed

worldwide, challenging batteries, e-motors, drivelines,

hybrids, and fuel cells.

Scalable up to 3 MW and 1,500 V, E-STORAGE BTE com-

bines outstanding control accuracy with dynamic perfor-

mance, enabling realistic battery emulation and precise

reproduction of load profiles. Automated configuration

changes minimize downtime and increase utilization, while

0.01 % FS accuracy ensures reliable results. With air- and

water-cooled variants, the portfolio continues to evolve to

meet next-generation testing demands.

After ten years, E-STORAGE BTE remains a cornerstone

of AVL’s e-mobility testing portfolio – delivering precision,

versatility, and innovation for the future of e-mobility.

Testing ­Excellence

Designed with standardized industrial-grade components,

ConsysActive systems combine robust performance with

simplified service and spare parts management. All units are

available with refrigerants below 2500 GWP as well as a CO2

version for environmentally friendly operation. With its holistic

and versatile design, ConsysActive supports a wide range of

applications, from AVL ThermalLab™ to batteries, fuel cells,

e-motors, and e-axles, advancing both testing reliability and

sustainability.

dentifying where energy is used effectively and where

losses occur is crucial for developing modern BEVs. Effi-

ciency has become the key to range, cost, and competi-

tiveness. To master this challenge, AVL applies energy flow

testing using the AVL Vehicle Powertrain TS™ platform,

specifically designed for the development and validation of

electric and hybrid powertrains.

The energy flow testbed uses hub-mounted dynamome-

ters, direct torque measurement, and synchronized sensors

to provide a comprehensive overview of energy consump-

tion – from the wall to the wheel – including non-drive

consumers, e.g., HVAC systems, which are often excluded

from legislative cycles.

Combined with the AVL toolchain, the method delivers

reproducible and highly transparent results. With this front-

loading approach, efficiency losses can be identified much

earlier than in conventional prototype testing. OEMs gain

greater flexibility for design changes, more accurate range

optimization, and ultimately a faster time to market.
