As an engineering service provider, invenio offers the holistic development of high-voltage batteries suitable for series production for BEVs and PHEVs. The scope of services can be realised in support of an existing development team or as outsourced system development for partial scopes. If required, on-site support is also possible.
Our services include:
Concept
Installation space analyses
Manufacturing-
suitable
construction
Drawing-
creation
(GD and T)
Simulation (FEM, Crush, Crash, CFD)
Optimisation (weight and costs)
Supplier-
support
Concept development includes analysis, goal description, application of concept methods, and evaluation. Through internal production locations for component scopes and partnerships with numerous suppliers, our developers can offer production-oriented development, drawing creation and supplier support.
The optimisation of assemblies, the reduction of component costs, topology optimisations or simulations of static or dynamic scopes round off our internal development scope of high-voltage batteries.
Intelligent invenio software (VT-DMU) for checking derivatives, distances and assemblies
Short-term production of prototypes to secure your test set-up
Independent technically sound second opinion on one's own specialist area
Standard-compliant drawings and specifications for enquiries with suppliers
Our development scope includes the architecture selection of the battery cell, its contacting and storage. In addition, the connection of several modules – if modules still exist – and the control system to form an overall electrical system.
Depending on the concept, cooling plates or cooling lines can be integrated between the cells, modules or housings, or immersion cooling can be used for direct cooling. In a sealed housing, as a load-bearing or non-load-bearing structure of the vehicle, the energy storage system becomes a crash-relevant overall system.
We provide support in all development batches of high-voltage batteries up to series production and also with series production support.

Benefit from our independent opinion, concept development, evaluation, selection and constructive implementation of components. We can take over the preparation of enquiry documents, as well as the implementation of the enquiry and evaluation for decision documents and the coordination of suppliers.
Manufacturing processes and example scopes for traction batteries:
Aluminium extrusion for e.g. housings, modules and crash subjects
Sheet metal forming and stamped parts for e.g. enclosures, cell contact systems (CCS), holders and busbars
Plastic injection moulded parts for e.g. cooling lines, insulation components, plugs, housings and holders
Machining for e.g. contact pins, castings and spacer sleeves
Plastic pipes for e.g. cooling lines
Welding for e.g. cell contacts, housings and spacer sleeves
Sealing with e.g. liquid seals, moulded seals or O-rings
Aluminium die casting, chill casting and sand casting for e.g. holders, housings, connector interfaces and crash themes
