Range of products specifically provided for electric vehicles ensures reliable and safe performance of batteries, powertrain components and on-board electrical systems.
Bietigheim-Bissingen / Hannover. 1. April 2019 - The Engineered Materials Group of Parker Hannifin Corporation, the global leader in motion and control technologies, offers an extensive portfolio of products and solutions for electric vehicles in the areas of sealing, shielding and thermal management.
Electric vehicles with their high-voltage systems and power electronics confront automotive OEMs and their suppliers with special challenges in the areas of sealing, shielding of electrical interference signals and thermal management. Drawing on decades of experience in these areas, in all kinds of automotive as well as electronic system applications, Parker offers an extensive range of solutions.
Solutions Hallmarked by Efficiency and Reliability
Components of alternative drive systems such as electric axles, batteries, power electronics and their control units entail a multitude of sealing and shielding requirements. All of them are aimed at ensuring efficient and reliable performance of on-board electrical systems, from charging current couplings to the traction battery to the electric drive motor. Established sealing solutions such as O-rings, press-in-place seals, rotary seals, integral seals (composite sealing plates) are available for these purposes, as well as other products for electrical shielding and heat dissipation such as EMI components, thermal gels and pads. Special benefits can be achieved by combining these functions in one component.
Environmental Sealing of Electrical On-Board Systems
Drive systems for hybrid electric and battery electric vehicles consist of a multitude of complex components with specific tasks and requirements. Electronic control units, power electronics or the electrified drive axle and their individual assemblies have to be reliably protected against environmental influences and electromagnetic interference. For these requirements, Parker offers an extensive product range for shielding and sealing of chassis/housing elements. Customers are able to select from a multitude of press-in-place frame seals, O-ring seals, chassis/housing components with integrated sealing systems to thermally conductive sealing gels.
For sealing larger chassis/housings, such as those of the battery system, Parker offers XXL-size sealing solutions. Large circumferential seals, produced either by extrusion or, of higher quality, without joints, are the ideal solution for large chassis/housings. Unlike adhesion-bonded chassis/housings, they enable easy revision when repairs are necessary.
For electromagnetic shielding that is intended to prevent undesirable interference with the components either from external sources or adjacent electrical systems, special-purpose sealing solutions using EMI materials are available.
The compact design spaces of on-board electric systems such as the traction battery, power electronics and electric motor combined with their high power density require efficient and intelligent thermal management solutions. Air-cooled or liquid-cooled systems call for sealing solutions with high temperature stability and long life. Inefficient cooling would result in major trouble for the total system and may lead to massive performance loss up to and including total destruction of the electronic components of the hybrid electric or battery electric vehicles.
In this area, Parker is able to draw on longstanding experience in the development of sealing compounds for cooling systems with particularly challenging demands in terms of service life and chemical resistance. In addition to static and dynamic sealing solutions such as flange, shaft or molded seals, Parker offers special thermal gels or pads for heat dissipation of electronic components or chassis/housings.
