Battery Development for Electric Vehicles

From Technological Innovation to Series Industrialization

We push technology forward by focusing on getting products to market faster, increasing safety, and prioritizing recycling and sustainability. Furthermore, we create custom battery solutions for all types of vehicles, aiming to keep costs down and speed up the time to market. Our services cover everything from developing new concepts to perfecting the production process for large-scale manufacturing.

The main challenge in vehicle electrification is developing effective batteries. Both new and established vehicle manufacturers face ongoing and emerging challenges as the technology evolves rapidly with each new market entrant. The focus is on optimizing efficiency, safety, and industrialization costs.

At AVL, we propel technological advancement by crafting customized battery solutions based on our customers' specific needs, aiming to reduce costs and accelerate market readiness. We handle all aspects of development, from initial innovation to preparing manufacturing processes for series production.  

Since 2007, we have concentrated on developing safe, cost-efficient, environmentally friendly battery systems with high energy density. Throughout the years, our focus has been on producing top-quality products with a strong emphasis on functional design and innovative production processes. We devise strategies for individual assembly steps and flexible small-batch production of modules and battery systems. The projects listed below represent just a few examples of our extensive work:

  • AVL Lighthouse

Our internal project to advance electrification by focusing on battery, EDU, and thermal system development and integration. AVL also leads the integration of E/E systems, control systems, vehicle aerodynamics, and chassis enhancements.

  • McLaren Speedtail

Battery pack development project from initial concept to start of production (SOP), incorporating modules into the battery pack for hybrid electric vehicle. The project was executed at the AVL Battery Innovation Center, where small series of battery packs were manufactured.

  • LG

Pouch module with a coated aluminum monoframe. Now produced in very large batches and installed in the Audi e-tron and Porsche Taycan, for example.

Development methodology

At AVL, we have the expertise, methods, and tools for the entire development process. These include simulation tools and service, virtual testing and validation, creation of prototypes, and integration into the complete vehicle.

Innovative capability

We have been actively involved in automobile production for more than 75 years, and have optimized our processes for the swift transition from innovation to series-ready products. For batteries in particular, we focus on parallelization of functional and production process development.

Innovative Imersion Cooling
No Thermal Propagation

Our innovative battery concepts allow us to reduce CO2 emissions and increase the 24/7 safety of battery-electric vehicles. The key phrase is: no propagation. If a thermal runaway looks likely at cell level, flames must not spread to neighboring cells. Battery design of this type requires a detailed, careful development and verification process. We have developed a unique simulation methodology to realize this swiftly and in a cost-efficient manner. This combines physical tests at cell level with simulations at module and pack level - including the corresponding vehicle interfaces.

Weight savings, component reductions, easier assembly and service, as well as recycling aspects, all play a key role in the entire battery development process. AVL has already brought solutions with a high level of energy density to market, with low unit and production costs. Our expertise is a decisive advantage for future innovations.

Battery Modules and Packs

Benefit from our engineering expertise throughout the entire battery development process – from the initial idea to SOP and beyond. We offer a comprehensive set of services: in addition to engineering new batteries or derivatives, we support you in setting up cost-optimized, sustainable, and secure series production.

Battery Simulation
Simulation in Battery Development

AVL simulation software and methods enable fast and efficient development of no-propagation battery designs, structural cell integration, thermal systems for rapid charging, and many other solutions.

Battery BMS Rendering
Software and Controls for BEV

Our proven Battery Management System (BMS), developed in-house, facilitates safe battery control, both at the prototype stage and in series – including comprehensive diagnosis (OBD, ISO26262) and precise monitoring. Featuring its own software and hardware, the BMS is designed for all battery types and sizes.

 Battery Innovation Center
Battery Industrialization and Manufacturing

In addition to building, testing, and validating batteries, we also develop the associated industrialization for you at our AVL Battery Innovation Center. This allows us to provide production-ready development, including production planning and process validation.

Battery Testing Solutions

For battery (module/pack) testing, we offer complete test systems, stand-alone equipment, or even entire turnkey test labs.

As an independent service provider, AVL has been a leading battery technology company for nearly two decades.

From the electrode to the pack, we provide complete vehicle integration. We are pioneers, especially with regards to safety, we are already able to realize the no propagation objectives for the next generation of battery electric vehicles.

Our Battery Innovation Center (BIC) in Graz, opened in 2021, added another key future platform to our portfolio, enabling us to provide the best possible support for the automotive industry and its suppliers during the conversion to electromobility. The facility, which covers an area of 1600 square meters, supports all of AVL’s expertise in innovative battery concepts around the world, both in terms of functionality and production process development.
