Sealing Shielding

Observations From the Electric & Hybrid Vehicle Technology Expo NA

Daniel with Customer_Observations from the Electric & Hybrid Vehicle Tech Expo North America_Parker CHOAnother Electric & Hybrid Vehicle Tech Expo North America has concluded and it is evident that this show has grown by leaps and bounds. In just a few years since Parker Hannifin has started exhibiting, the interest and demand in EVs and PHEVs have seemingly exploded, and the 2019 show proved to have the most suppliers and attendees the show has ever seen.

From nearly every continent across the globe, there are innovators fast developing new and exciting technologies that will make the future of driving cleaner, safer, and more reliable. The Electric & Hybrid Vehicle Tech Expo North America is a must-attend event for OEMs, tier suppliers, and designers looking for the latest in the development and application of technology for electric vehicles. With over 8,500 attendees, 650 suppliers, and 150 speakers in 2019, Electric & Hybrid Vehicle Tech Expo North America is fast becoming the largest EV technology show in North America. 

This year, Parker Hannifin Engineered Materials Group (EMG) featured many new and innovative products -- from heat-dissipating thermal interface materials, to electromagnetic interference (EMI) shielding products such as plastics, gaskets, and coatings, sealing for complex groove designs, and closure force reduction, the Engineered Materials Group from Parker Hannifin is your single source provider for sealing, shielding and thermal management components in electric vehicles.

So what was new this year from Parker Hannifin EMG?

 

Large format battery seals

Parker's sealing solutions for batteries are available in large formats. Our versatile materials address your specific needs such as low compression set, temperature resistance, fire resistance, media resistance, and low closure force. Additionally, our seals can be customized in a wide range of geometries.

Parker has developed a new hollow "keyhole" seal design for easier installation, providing significantly lower compression load forces while maintaining seal reliability. Other key advantages of the keyhole profile design include improved rollover stability performance, larger application gap tolerances and lower reduction which provides lower application costs that would normally result from fasteners and thinner covers. 

Our expertise in material science is the critical foundation to offer engineered products made from a wide range of standard and tailor-made compounds which can be specifically adapted to your application requirements.

Parker sealing solutions are available in various product designs, from O-Rings, press-in-place seals, extruded and spliced seals to custom designs. 

 

 

Thermal interface materials for battery heat dissipation

Parker Chomerics provides effective heat dissipation technologies in the form of thermal interface materials that are either robotically liquid dispensed or a die-cut thermally conductive gap pad. Liquid dispensed thermally conductive materials such as THERM-A-GAP® GELS offer the reliability of traditional thermal interface materials, but with the ability to be robotically dispensed for fast, effective high volume productions.

And with a wide variety of performance and polymer options available, THERM-A-GAP GELS are ideal for most battery heat dissipation applications. 

THERM-A-GAP thermal gap filler pads dissipate heat generated from the battery pack and add additional support, vibration dampening or dialectic strength. They are also available in a variety of performance options from 1 W/m-K up to 6.5 W/m-K thermal conductivity. 
 

 

EMI shielding technologies for EV electronics

Beyond effective thermal management, another technology challenge Parker Chomerics helps to solve is the need to shield against EMI. The cables that travel between the battery and engine, as well as the battery and charger, see high current produced at low frequency. This produces a large magnetic field that can negatively affect other electronics within the vehicle. High shielding attenuation is also required to protect the battery and its circuits from any incoming EMI. Shielding is also required in the increased technology and communication required to ensure the proper advanced driver-assistance systems (ADAS) 

Replacement of metal housings with PREMIER electrically conductive plastic can contribute to reducing vehicle weight and cutting manufacturing costs. Here, an electrically conductive plastic alternative can be exchanged for the battery electronic control unit’s (ECU) conventional die-cast aluminum housing. Metal to plastic conversions not only eliminate 35% of the housing weight but also provide cost reductions of up to 65% by eliminating secondary operations such as assembly and machining.

As electric and hybrid vehicles grow in popularity, Parker offers the engineering and materials expertise to help EV manufacturers produce the vehicles that consumers want at the scale needed.

With thousands of sealing, shielding, and thermal management solutions available, and over 50 locations around the globe, Parker is ready today to engineer solutions for your most critical EV applications.
