Freudenberg Introduces Seals for Electric Vehicles

Freudenberg Sealing Technologies debuted its newest sealing solution at The Battery Show which is designed specifically for electric vehicle (EV) applications. It is a sealed, rectangular overmold which creates an impermeable seal to protect the power electronics found in EVs. 

Creating a tight seal on rectangular busbars has proven to be a challenge in the past. Often they have not provided as tight a seal as desired and required extra work while also taking up additional space in vehicles which is often at a premium. However, the new Freudenberg seal overcomes these challenges. Per the company, it features an elastomeric layer which is applied to the rectangular busbar and bonds firmly with the metallic conductor and the surrounding plastic later in the manufacturing process which helps to ensure a tight seal without taking up additional space in a vehicle or requiring additional post-processing. 

"Sealing rectangular shapes is considered the pinnacle in sealing technology, as leakage points often occur in the corners. Thanks to an elastomer layer between the metal and plastic we can now produce sealed busbars – and in a way that saves valuable space, as component and seal virtually become one. This new solution from Freudenberg Sealing Technologies enables our customers to seal their busbars even more reliably, while at the same time offering a high degree of design latitude," said Parisa Burger, Business Development Manager and Project Manager at Freudenberg, in the company's press release announcing the debut of the new sealing solution.

Schaeffler Exhibits Range of Electrification Solutions

At the Electric & Hybrid Vehicle Technology Expo, Schaeffler showcased its wide range of products for use in EVs, including hybrid- and full-electric applications. These include electric axles, thermal management modules with integrated cooling, fuel cell stacks, battery systems and more. 

In addition, director of engineering Dr. Rashid Farahati gave a presentation at the event on how solid-state batteries could be the next generation of development focus for EVs. Dr. Farahati discussed the technology itself as well as current challenges in manufacturing this battery type and how those challenges could be overcome. 

Battery technology is an area in which many companies are researching new options as there remains a need to not only increase the capabilities of current battery chemistries but also improve their sustainability.

Monolith Shows AI's Ability to Aid with Battery Testing

Artificial intelligence (AI) software provider Monolith spoke at The Battery Show about how AI can be used by engineers to speed up development and integration of battery systems. Earlier this year the company introduced an updated version of its machine learning technology Next Test Recommender (NTR) which can aid with these development efforts. 

NTR provides engineers with active recommendations on the validation tests to run during the development of hard-to-model, nonlinear products such as batteries and fuel cells. According to Monolith, this technology can help to reduce testing up to 70%. 

"In the fast-paced EV market, testing batteries has become a significant bottleneck, hindering the timely launch of EVs. The escalating demand and intense competitive pressure to enhance the range and charging times compound this challenge exponentially," said Dr. Richard Ahlfeld, CEO and founder of Monolith, in an excerpt from his Battery Show speech. 

"Engineers perform battery tests across thousands of channels generating terabytes of data per week. They’re running out of test stands and don’t know what optimal tests to run, and certainly don’t have the ability to learn from this vast amount of data as quickly as they need. 

"This is where AI comes in. Through the ability to learn from data, test engineers can understand behavior characteristics that are so complex, that without the right tools it is incredibly difficult to decipher. AI software that learns from real world test data is a reliable and effective means for solving the intractable physics of batteries that current simulation and test planning tools don’t efficiently solve."

Festo's CPX-MPA fieldbus-enabled valve terminal controller, the DFPC linear actuator for a knife gate valve, the KVZA pre-assembled process valve, and the VZXA angle seat valve were all part of the exhibit demo. 

The company also exhibited how its technology can be used to disassemble battery housings and remove various components which is usually a labor intensive process. 

"In order to meet the needs of the rapidly growing EV market, the United States will need to expand battery recycling capabilities, as well as grow our domestic capacity for producing battery precursor materials," said Jigar Shah, Director, Loan Programs Office at the U.S. Department of Energy. "By lowering the cost of the critical materials for lithium-ion batteries using recycled materials, electric vehicles can become more accessible to lower income communities."

Honeywell Exhibits Safety Technology for EVs

Safety is a key concern when it comes to electric vehicles because of the high voltages used and potential for thermal runaway in batteries, among others. Honeywell has developed several solutions to help protect those working with and driving EVs. 

Among these technologies are battery safety sensors which can be integrated into battery packs. The sensors can detect thermal runaway and alert drivers so they can take appropriate action. Battery manufacturers who incorporate these sensors into their systems can benefit as well as the technology helps them meet international battery fire safety standards. 

Honeywell is working with Nexceris, a developer of Li-ion Tamer lithium-ion gas detection solutions, to develop sensors which can detect thermal runaway faster to help further improve safety.
