Cell contact systems for low-voltage battery systems
A dynamic, electrified future requires powerful, safe and sustainable battery systems. Diehl Metal Applications' (DMA) cell contact systems form the heart of modern low-voltage battery systems, whether they are used for urban mobility, industrial applications, or new energy and storage solutions.
Modular. Efficient. Forward-looking.
We offer customized solutions for various cell configurations that are precision-manufactured and flexible to combine. By pairing them with connectors and housings, busbars and bimetals, welding pads, power pins, and stamping grids, we create battery systems that meet the highest performance, safety, and efficiency demands of our customers.
Our variable design can be adapted to every application:
- Short tolerance chains for a precise fit
- Waterproof construction for maximum safety
- Lower heat generation for longer runtimes
- Performance optimization through the intelligent use of materials
- Modularity for flexible applications
Intelligent Cell Connections — Innovation from a Single Source
Advantages for Your Battery Systems:
- Tabless Cell Generation 21700 & 18650: Less resistance and more power
- High output power (AC rated power)
- Improved heat dissipation and efficient heat transfer
- Reduction of electrical connections: Harmonized contacts and fewer interfaces
These features enable a more compact, powerful, and durable battery unit. The modular design also supports optimized assembly and an efficient logistics concept.
