The e-axle is a key component in an electric vehicle. This is where motor, transmission, and power electronics merge into a compact module that can also be expanded to include functions such as a DC/DC converter and charging. Every increase in the degree of integration saves costs and helps to increase system- efficiency. Other advantages are smaller dimensions, lower weight, reduced interfaces, and improvements with regard to electromagnetic radiation.
Recognizing market requirements at an early stage and mapping them in services and development methods has always been what has distinguished AVL. We develop your e-drive unit in such a way that it optimally meets end user expectations.
Optimization of Efficiency
In order to achieve maximum ranges, you need a high level of efficiency. This requires detailed understanding of the e-axle and the overall system, perfect coordination of the influencing parameters, and the reduction of losses in the system.
Less Weight, Longer Range
Reducing the weight of a vehicle has a direct, positive impact on the achievable range, which is why the propulsion system should be as light as possible. It is often possible to reduce weight by optimizing the design of the individual components, and this can be visualized early in the development cycle using advanced simulation methods.
Optimizing Acoustics
When it comes to NVH (noise, vibration, harshness), you can only achieve perfect results if the individual propulsion system components are coordinated and improved as a whole.
Cost and Lifecycle CO2 Reduction.
Under high competitive pressure, automobile manufacturers and suppliers feel compelled to keep development costs and the associated carbon footprint of the product as low as possible. At AVL, design-to-cost, as well as design-to-CO2 is taken into account consistently in our projects.
Compression of Design
In terms of volume and shape, the design of the propulsion system is limited by the chassis geometry and axle sub-frame structure. Therefore, the e-axle system must be designed to be as compact as possible – while also ensuring maximum power density.
Short Time to Market
Another competitive advantage is bringing new developments to market as quickly as possible. This allows expenses to be amortized more quickly, or simply enables a product to be first on the market.
With our support, your e-axle system will meet market requirements. Our greatest strength lies in our integration expertise: We consider the overall system and know the targets that the vehicle needs to achieve.
For example, to optimize efficiency, we recommend our two-speed e-axle system for your passenger car, premium SUV, and light-duty commercial vehicles. The optimal efficiency of the system reduces costs and improves performance.
Our extensive use of advanced simulation tools supports error-free processing and reduces the use of prototypes.
We keep your product costs low with our modular approach: Our e-axles are compact units that integrate the necessary e-drive components – e-motor, transmission, and inverter – and leave maximum space for the battery. These components power the axle of your vehicle directly and reduce complexity – as an out-of-the-box solution for battery electric (BEV) and hybrid electric vehicles (HEV).
This compact design has two additional advantages: optimal integration into the available space, and reduction of weight – a bonus when it comes to improving electric driving range.
Our modular approach also accelerates your time to market: With pre-designed solutions that only need to be customized, we reach the finish line much quicker than if we had to design each individual solution from scratch.
System Integration from a Single Source
With us you get comprehensive expertise in all key areas, under one roof.
Optimization of Your Total Development Costs
We have a team dedicated to "production development, cost optimization, and lifecycle CO2 assessment". This is how we reduce the costs of your individual components and your overall system, and increase sustainability.
Short Time to Market
Our modular approach to e-drive components shortens the development process for you in order to achieve the desired result.
Target Fulfillment
We define application requirements and break these down into subsystem and components. We factor this into the design. After extensive testing, we bring everything together in the overall system for you.
