Schreiner ProTech, a global developer and manufacturer, has expanded its series of pressure compensation seal (PCS) solutions for the rapidly growing electric vehicles sector. The full range now comprises solutions for charging protection, battery, and motor production and lifespan management, and components marking and sealing.
An emerging trend for years, electric vehicles continue to make steady inroads in the automotive market. Most prominently, in August California regulators agreed to ban the sale of new gasoline-fueled cars by 2035.
From a corporate standpoint, Ford is investing $30 billion toward its goal of making half its vehicles electric by 2030, while GM’s $35 billion investment through 2025 targets zero overall emissions. In addition, Volkswagen and Germany-based engineering giant Siemens are pouring nearly half a billion dollars into doubling its North American charging station infrastructure over the next two years.
In addition to their obvious environmental advantages, e-vehicles also bring a modicum of manufacturing ease, as they require fewer mechanical components than their conventional combustion engine counterparts. However, unsurprisingly EVshave decidedly more electrical components requiring proper labeling and protection to ensure long-term functionality.
Notably, EVs need robust, durable pressure compensation solutions in a variety of areas — including the battery and driving column — that must be resistant to steam jet cleaning. Here, it’s increasingly important for such solutions to be lightweight and small in size, as these simplify production processes and save on warehousing space and shipping costs.
To meet these needs, Schreiner ProTech’s expanded range of pressure compensation seals (PCS) include:
- Vehicle charging protection: During the EV charging process, the electric current generated leads to high temperatures in the charging plug and socket area. These temperature fluctuations result in pressure differences in the electronic housing. A modified version of Schreiner ProTech’s PCS HighProtect pressure compensation seals comprise a membrane that protects electronic housings
against potential damage.
- Battery management: In addition to various PCS solutions, Schreiner ProTech’s PreScript warning and information plates help manage the production, storage, installation and lifespan of EV batteries.
- Motor marking: The motor of an e-vehicle must deliver reliable performance with low-noise emissions. Schreiner ProTech supplies numerous marking solutions as well as double-sided adhesive die-cut parts for precise, noise reducing component assembly. To meet rugged needs, its segment-specific PCS HighProtect is extremely flat and particularly steam jet-resistant.
- Complex power-electronics units, which control the motor and convert direct current into alternating current for the powertrain, Schreiner ProTech’s customized PCS HighProtect and self-adhesive pressure compensation seals provide a worry-free combination of housing seals and warning/information plates.
For added value, Schreiner ProTech’s PCS products come in adhesive rolls that can be automatically applied and made translucent for easier product labeling and camera-readable traceability. Such solutions also make mandatory, chemical-resistant labeling of high-voltage parts simpler, and more user-friendly throughout the supply chain.
