Battery components
With our battery components, we are ideally placed for alternative drive technologies. The major advantage for our customers: ElringKlinger offers development and prototype construction to testing and series production from a single source. We have been a series supplier in battery technology for more than 10 years.
Cell contact systems
- Specifically coordinated
- Mounted directly on the cell unit in various expansion stages and welded
- Plastic carrier frame holds cell connectors, ensuring that they can be installed in all tolerance positions
- Integrated voltage and temperature sensors
- Monitoring electronics (CSC) can also be integrated
- Automotive plug systems or screw connectors
Cell housings and covers
- Cylindrical, prismatic, pouch
- Exceptionally reliable even in large volumes
- Reduced number of components and complexity
- Reduced use of materials
- Lower CO2 footprint by up to 40 percent
Pressure equalizing units
Compensates for pressure differences in the storage housing (e.g. when driving up and down mountains, with temperature differences, for air transport in aircraft cargo holds without pressure equalization)
- With integrated safety function for critical excess pressure
Plastic battery housing and modules
- Weight and cost reduction
- Reduced installation work
- Integrated functions, reduced number of components
- Optimized NVH properties
- Low thermal conductivity
- Excellent electrical insulation
ElroForm™ metallic assemblies/formed parts
- e.g. battery housing, module housing
- Carrier layer provides structural strength and rigidity
- Weight and cost reduction
- Functions can be integrated
- Optimized NVH properties
ElroForm™ and ElroShield™ EV metallic battery covers
- e.g. for module separators
- One or more parts
- Functions can be integrated
- For high requirements for crash safety, thermal conditions (up to 1,100°C), particle coating and acoustics
Thermal propagation measures (covers)
- ElroSafe™ (lightweight, continuous fiber-reinforced thermoplastic composite material)
- ElroShield™ EV (metallic, multi-layer)
- Optimum protection against burn through and particle coating
Controlled gas feed during thermal propagation events
Elastomer/metal elastomer sealing systems
- e.g. for large flanges (battery housing)
- For components subject to high loads
- Adaptable to any geometries
- Fast installation, low space requirements
- Totally safe, even with low sealing pressures
- Long-term corrosion protection
- Double lip system possible
- Elastomer materials developed in-house by ElringKlinger
MetaloSeal™ metal bead gaskets
- Functional coatings, e.g. conductive coating for EMC shielding
- Installed in direct line of force
- Positioning plates and retaining clips for quick and reliable installation, vertical and upside down
- High media, temperature and pressure resistance
TopSeal™ deep-drawn covers
- e.g. battery module cover
- Topographic support of the integrated seal using embossed stoppers
- Improved corrosion resistance
- With functional integration, e.g. screws, ventilation elements
Best possible screening against electromagnetic radiation
Made of high-performance plastics
e.g. insulation elements, cell cover and PTFE membrane for pressure equalization elements
- Chemical resistance to aggressive media
- Very reliable at high temperatures
- Reliable ventilation with customized designs
