AVL is strengthening its position in electric mobility by advancing comprehensive electric driveline engineering solutions designed to improve propulsion efficiency, power density, and system integration in next-generation electrified vehicles. AVL enables automotive manufacturers to accelerate electrification programs by combining advanced powertrain architectures, digital engineering platforms, and robust validation technologies.

The company’s electric driveline development portfolio spans the full engineering lifecycle, from concept design and system simulation to hardware validation and production integration. By leveraging expertise across mechanical, electrical, thermal, and software engineering domains, AVL supports the development of high-performance electric propulsion systems that deliver improved vehicle efficiency, reliability, and driving performance.

System-Level Electric Driveline Architecture Development

AVL adopts an approach that optimizes complete electric propulsion systems by integrating electric machines, power electronics, transmission systems, and battery interfaces into unified drivetrain platforms. The company develops multiple driveline configurations, including centralized motor architectures, distributed propulsion systems, and integrated electric axle (e-axle) solutions.

These architectures are engineered to meet vehicle performance targets, energy efficiency requirements, packaging constraints, and cost objectives. By enabling coordinated co-development of drivetrain subsystems, AVL improves torque delivery efficiency, reduces overall system complexity, and enhances vehicle range and performance.

Electric Motor, Power Electronics, and Wide-Bandgap Semiconductor Integration

AVL provides advanced engineering capabilities for electric traction motors and inverter technologies, focusing on improving electromagnetic performance, torque density, and operational efficiency across wide speed and load ranges. The company supports multiple electric machine technologies, including permanent magnet synchronous motors and induction motor platforms, optimizing electromagnetic design to achieve high power density and improved efficiency.

A significant area of AVL’s inverter development involves the integration of wide-bandgap semiconductor technologies such as Silicon Carbide (SiC) and Gallium Nitride (GaN). These advanced semiconductor materials enable higher switching frequencies, reduced switching losses, and improved thermal performance compared to traditional silicon-based power devices. The adoption of SiC and GaN technologies allows AVL to design compact, high-efficiency inverter systems that improve drivetrain responsiveness, reduce energy losses, and support extended electric vehicle driving range.

Transmission and Mechanical Driveline Optimization

Beyond electric propulsion hardware, AVL develops advanced mechanical drivetrain components, including single-speed and multi-speed transmissions, gear reduction systems, and differential assemblies. The company focuses on maximizing torque transfer efficiency while minimizing frictional losses and mechanical wear.

AVL applies advanced tribological modeling, structural simulation, and durability testing to optimize gear geometry and mechanical load distribution. Noise, vibration, and harshness optimization is also a key development area, enabling quieter drivetrain operation and improved passenger comfort while enhancing mechanical efficiency.

Thermal Management and Cooling Technologies

Thermal management remains critical as electric propulsion systems continue to increase in power density. AVL develops integrated cooling solutions designed to regulate operating temperatures across motors, inverters, and drivetrain components.

Using advanced multiphysics simulation tools, AVL models heat generation and thermal distribution to design optimized cooling architectures, including liquid cooling circuits, direct oil cooling strategies, and advanced heat exchanger integration. Effective thermal management ensures stable operation of high-power propulsion systems, protects semiconductor components, and improves overall drivetrain durability and efficiency.

Virtual Development and Validation Technologies

AVL utilizes advanced model-based development and digital engineering platforms to accelerate drivetrain design while reducing reliance on physical prototypes. These simulation tools allow detailed evaluation of power flow dynamics, energy consumption, and system performance under diverse operating scenarios and driving cycles.

The company also deploys software-in-the-loop (SiL), hardware-in-the-loop (HiL), and integrated system validation platforms to verify control software and electronic system functionality before vehicle integration. These validation frameworks enable faster calibration, improved performance optimization, and compliance with automotive safety and reliability standards.

Integrated E-Axle and Intelligent Control Software Development

AVL is actively developing compact and scalable e-axle propulsion modules that combine electric motors, power electronics, transmissions, and control units into highly integrated drivetrain systems. These modular propulsion platforms improve power density, reduce packaging complexity, and support flexible vehicle platform scalability across passenger and commercial vehicle segments. 

Complementing hardware integration, AVL develops advanced control algorithms that manage torque delivery, regenerative braking, drivetrain stability, and overall energy optimization. These intelligent control systems coordinate motor operation, inverter switching control, and powertrain energy management, enabling improved drivability and enhanced vehicle efficiency.

Through its end-to-end electrification engineering capabilities, AVL supports development across concept design, simulation, prototype validation, and series production integration. The company’s integrated engineering approach enables manufacturers to accelerate the deployment of high-efficiency and high-performance electric propulsion systems while meeting evolving sustainability and electrification targets.
