BBW Lasertechnik is your expert for laser welding of battery cells - an area that is becoming increasingly important. With the increasing demand for electromobility and the use of home storage systems and stationary energy storage systems, laser welding of battery cells is more important today than ever before.
We have many years of experience in laser material processing and continue to grow with each individual request. In combination with our expertise, this makes us the ideal partner for your project involving battery modules, packs and more. Thanks to a high proportion of in-house production and state-of-the-art equipment, we can respond flexibly to your individual requirements.
Our battery cell services can be divided into four core areas:
A busbar is a current-carrying rail. In busbar welding or cell connector welding, the cell connectors are pressed onto the cell poles without a gap using a hold-down device and then welded with a laser. This method ensures a precise and stable connection, which is necessary for the performance and safety of the battery.
In case welding, the case parts are usually pressed together with the cells for force and displacement and then welded with a laser in the pressed state. This process ensures that the housing parts remain firmly and permanently bonded together, increasing the structural integrity and longevity of the battery module.
The voltage taps are precisely positioned and held down on the cell connectors before they are welded. This precise positioning and fixing before welding ensures a reliable and stable electrical connection, which is crucial for accurate voltage measurement and battery safety.
The sheet metal parts of the temperature control plates must be positioned and fixed without gaps to ensure a tight laser welded joint. A precise and tight connection is the prerequisite for enabling effective cooling and temperature control of the battery. This in turn increases the performance and service life of the battery.
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:
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.

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.
