Energy storage electrical equipment seal

What type of sealing is used for power electronics?

The sealings to connect power electronics are usually integrated directly into the plug. Silicon rubber-based components are used for this application in most cases. They have increased resistance toward high electrical voltages, and their surface does not carbonize, as opposed to carbon-based polymers.

What are cell sealing components?

The following pages will discuss the main sealing components for cells and the entire battery system. Cell sealing components must electrically isolate the two pole connectors from each other. The sealing components used also have to be chemically stable toward organic electrolytes.

Why do batteries need to be sealed?

The sealing components used also have to be chemically stable toward organic electrolytes. In addition, during the battery’s entire service life, the sealing mater-ial must not leach out contaminating substances into the battery electrolyte as this could have a long-term negative influence on the cells’ electrochemistry.

Can a seal design improve battery cooling cycles for electric vehicles?

Kritzer P, Clemens M, Heldmann R (2011) Innovative seals: a robust and reliable seal design can provide eficient battery cooling cycles for electric vehicles and hybrid electric vehicles. Engine Technology International, June 2011, p. 64

What are plug & seal components?

Plug & Seal components are already being used as standard in vehicle cooling systems and cooling modules of hybrid and electric vehicle batteries. Additional requirements for battery cooling systems can be met with sealed plastic pipe con-nectors and branched, flow-optimized components (Fig. 10.3).

What elastomers are used to seal pole feed-through?

Current approaches use specially developed, polyolefin-based elastomers (ethylene-propylene-diene monomers [EPDM]) as cell sealing material. These materials reliably seal the pole feed-through even under the prevailing operating conditions.
