For battery cell housings, OEMs and battery manufacturers need a system supplier who already provides intensive support during the development phase and, building on this, establishes custom-fit production solutions – and within the framework of an iterative process.
The battery cell housing is a central and at the same time exceptionally demanding task in the automotive sector: on the one hand, enormous quantities are required, on the other hand, high production requirements apply - from absolute tightness and no contamination to architecture-dependent, individual geometry.
Consequently, there are no standard solutions for the development and production of battery cell housings - and a flexible partner is required whose know-how and expertise covers the entire process from development to production.
Against the background of this complex task, aft automotive sees itself as part of a larger whole: We are a system supplier and support our customers right from the start of the technical development of the battery. The resulting production solutions are developed iteratively: every decision is examined holistically, weighed up against alternatives and adapted again and again if necessary.
We combine innovative system development with meticulous engineering craftsmanship, agility with reliable project management and comprehensive production planning with careful quality planning. The end result is highly efficient production sites with performance benchmarks
In the development of a battery cell housing, you have to meet the functional, safety-related and production-specific requirements – a complex task. The most important features at a glance:
Adherence to the opening pressure of the predetermined breaking point
Simulations for avoidance of heat transitions
Laboratory determination of electrolyte-resistant materials
z.B. Perfect filling with burr-free filling opening
Elastomeric sealing and precisely fitting design and material selection
Optimal welding and joining parameters
Design-for-assembly and interlinking of engineering and technical development
Prevention of leakage via the cell housing
Compliance with flammability, cleanliness, safety integrity and thermal runaway prevention standards
Responsible for the strategic product orientation at aft
There are various battery concepts such as cell-to-chassis or cell-to-pack, each of which has a different influence on the geometry. At the same time, many manufacturers are now looking to implement the industrialization of cell housings and the like. We already provide support during the development of the battery cell housing, derive functional requirements from this and create mechatronic concepts.
Each process is assessed according to whether it fits the requirements of the system – such as stability and thermal conductivity. Let’s take the burst valve as an example: During its development, we first validate the tightness and opening behavior and, based on this, we design the forming tools and the required laser welding systems.
This includes our promise as a "system provider". We plan and operate the complete factory for battery cell housing assemblies, including all production facilities, quality assurance and logistics. OEMs and battery manufacturers receive the solution for development, planning and production from a single source.
Incoming and outgoing goods are optimized directly at the plant so that subsequent or previous production steps benefit. Risks in the supply chain are identified at an early stage.
Interlinked production processes ensure agility and speed - the focus is on "cost per piece". Development, industrial engineering and quality management define an optimal process sequence.
Our objective is “0-error production”. High-resolution camera monitoring, in-line and in-process measurements and regular requalification and audits are used to achieve the goal.
Cleaning and drying processes ensure high component cleanliness. Production and assembly take place under clean room conditions.
automotive relies on end-to-end digitalization for all processes and systems. This offers significant advantages in system development, production and downstream processes involving the battery cell housing.
Each sub-step is validated and then the whole thing is developed further as part of a continuous optimization process.
We stand for flexible processes, short paths and scalable solutions.
We take a technology and process-independent view of challenges and choose new paths.
We follow a holistic approach, whereby each system development is backed up iteratively.
