Laser welding of battery cells

Our battery cell services can be divided into four core areas:

Welding with the laser tool significantly improves the quality and reliability of battery modules and battery packs. Take advantage of our comprehensive expertise in e-mobility and contact us for an initial consultation!

The production of battery modules with a laser beam has decisive advantages:

• Low heat input: welding with lasers enables extremely precise and controlled heat input. This minimizes the risk of thermally induced damage to the battery cells, resulting in improved battery quality and service life.
• Short cycle time: The high energy concentration of the laser beam means that battery cells can be joined together quickly and efficiently. This leads to shorter production times and increased production capacity.
• Process stability: The laser process offers high reproducibility and consistency. This ensures a consistently high quality of welded joints across all production batches.
• Online monitoring: Our modern laser welding systems enable continuous monitoring of the welding process in real time. As a result, any deviations can be detected and corrected immediately, which contributes to a further increase in production quality.
• High degree of automation: The use of laser welding technology enables extensive automation of the production process. This not only leads to a reduction in manual work processes, but also to improved efficiency and cost-effectiveness. 
• Material-locking connection: Thanks to the precise focus of the laser beam, battery cells can be joined together without the need for additional materials such as adhesives or solder alloys. The result is a material-to-material connection with high strength and stability.

All in all, laser welding in battery production offers a number of advantages that lead to improved product quality, efficiency and cost-effectiveness. BBW Lasertechnik will be happy to support you with your project on the road to electromobility.

BBW Lasertechnik is an ideal service provider for the laser welding of battery cells. We offer a complete portfolio from sample to series production and support our customers in every development phase. 

Comprehensive support - from the 1st sample to series production
We attach great importance to complete support, from the first sample through to series production. Regardless of whether you just need help getting started or want to place the entire series production in our hands - we are flexible and adapt to your needs. If you want to take over series production yourself, we will only support you in the sample phase and provide recommendations for selecting the right laser components.

Process development and recommendations for the series system
Thanks to our expertise in process development during the sample phase, we can provide you with valuable recommendations for selecting the optimum laser components for your series system. The result is seamless integration and maximum efficiency for your production.

Bundling of welding process and welding system 
We develop both individual welding processes and complete welding systems. This holistic approach ensures that all components are perfectly coordinated to achieve the best possible results.

Manufacture and procurement of individual parts and components
In addition to the development and implementation of welding processes, we can also take on the production of individual parts and the procurement of the required components for our customers. This means you receive everything from a single source and can rely on a smooth process.

Put your trust in BBW Lasertechnik for the laser welding of battery cells. Contact us today and let us successfully implement your project together!

In addition to various advantages of lasers in battery production, there are other reasons why we are an ideal partner for your e-mobility project - starting with our competent BBW team and our in-house metallography. 

• High traceability: We attach great importance to the transparency and traceability of our processes. We use state-of-the-art systems to ensure complete traceability of every welded joint for maximum quality assurance.

• In-house metallography: Our in-house metallography enables detailed analysis and documentation of welded joints in order to achieve the highest quality standards.

• Competent, trained & experienced personnel: Our team consists of highly qualified specialists with extensive training and many years of experience in the field of battery modules.

• Flexibility: We adapt our processes individually to the specific requirements of our customers in order to offer customized solutions that meet their needs.

• Sample production as an all-round package: From conception to production - we offer a comprehensive all-round package for the sample production of battery modules and packs.

• Handling of the entire supply chain: Thanks to our close cooperation with suppliers, we can guarantee seamless handling of the entire supply chain with the aim of enabling efficient and fast implementation of your project.

• Short decision-making paths: At BBW Lasertechnik, you benefit from short decision-making paths and direct communication in order to implement your requirements quickly and effectively.

• In-house project management: Our in-house project management ensures efficient coordination of all project steps and guarantees on-time completion of your battery modules.

BBW Lasertechnik processes various cell types, including pouch cells, cylindrical and prismatic cells. We support customers in the following areas of application: 

Air cabs and lightweight construction: Pouch cells
There are areas of application where lightweight construction is required, for example air cabs. Pouch cells are predominantly used here. These cell types are characterized by their low mass, which leads to improved performance and efficiency in aviation. BBW Lasertechnik offers precise laser welding solutions that are specially tailored to the requirements of pouch cells to ensure maximum performance and safety.

Car sector: cylindrical and prismatic cells
In the automotive Industry, the requirements for battery modules are high, but not as stringent as in the aviation sector. In this context, cylindrical cells (round cells) or prismatic cells are often used. By welding these cell types, we create efficient and durable connections that meet the high demands of the automotive industry.

Industrial trucks: Prismatic cells for counterweight batteries
In industrial trucks, such as forklift trucks, the battery also serves as a counterweight. For this reason, a corresponding mass density is required, which makes prismatic cells the preferred choice. BBW Lasertechnik offers specialized laser welding solutions that are tailored to the specific requirements of these applications and ensure optimum balance and performance.

Stationary storage: home storage and battery containers
In stationary storage systems, such as home storage systems or battery containers for grid balancing, the weight of the cells plays a subordinate role due to the stationary nature of the application. We have extensive experience in processing cells for home storage systems and battery containers and offer reliable welding solutions that ensure long-term stability and efficiency.
