CliPHvent vent valves increase battery safety of electric vehicles

CliPHvent vent valves from Parker Prädifa increase battery safety

The Prädifa Technology Division of Parker Hannifin has introduced CliPHvent, a new generation of vent valves for EV battery housings. In the event of pressure differences between the interior of a housing and the environment, as well as when sudden overpressure occurs inside a housing, CliPHvent ensures controlled pressure compensation or fast venting. This is particularly important in case of a thermal event in the traction batteries of electric vehicles.

Protection against sudden pressure increase caused by overheating

A “thermal event” or “thermal runaway” describes the sudden and rapid heating of a single or several battery cells due to a defect such as mechanical damage, an electrical short circuit, or overload. Especially in the powerful batteries supplying the propulsion energy in electric vehicles, thermal runaway causes huge amounts of gas to form inside the housing which leads to an uncontrolled and rapid rise in pressure and may have serious consequences up to and including the complete destruction of the traction battery and even the whole vehicle. CliPHvent vent valves from Parker Prädifa have been specifically developed to prevent that. By enabling fast venting via the integrated seal, they protect the battery housing resulting in higher safety of the traction battery. In the case of thermal runaway in a single battery cell, a domino effect, i.e., the spreading to adjacent cells followed by rapid propagation across the entire traction battery and its complete destruction, can be prevented.

Compensation of minor pressure differences, protection against ambient influences, easy installation

Minor pressure differences between the interior of the housing and the environment due to air pressure or temperature changes are compensated via a membrane. In addition, Parker aspire® membranes are water- and oil-repellent. As a result, CliPHvent vent valves provide reliable protection against ingress of external liquids and dirt.

The special, compact design of CliPHvent vent valves enables easy snap installation without the use of tools, on the battery housing or inside a bore.

New anode design to revolutionize electric aviation

New anode design to revolutionize electric aviation

Innovative strides have been made by Theion in battery technology through revolutionary anode chemistry. As part of lithium-sulfide battery research, the company has developed a lightweight polymeric host with special coatings to replace more modern chemical anodes such as graphite, silicon-rich graphite or lithium metal foils. Why is a lightweight and durable anode a key factor for lithium-sulfide batteries? Energy density is three times that of current conventional lithium-ion batteries at one-third the cost, requiring significantly less energy to produce. Scientifically validated results achieved tell of more than 2,000 charge and discharge cycles.
“Our innovation in lightweight, fast-charging battery chemistry makes lithium-sulfur batteries ideal for aviation electric thrusters, such as eVTOLs and conventional propulsion aircraft,” said Marek Slavik, co-founder of Theion.

CEO, Ulrich Ehmes, added, “Our new anode design is an important milestone. With our host anode chemistry, optimized and tested over several thousand cycles, we have solved the problem of dendrite and fast charging of lithium metal foils. This is a key component for our high-performance lithium-sulfur cell.”

New partnership for the electrification of boating

New partnership for the electrification of boating.

The partnership between Koelliker, which offers sustainable and smart mobility solutions, and Barchelettriche, a company that has been committed to eco-sustainable boating for years, was created to offer advanced electric mobility solutions on road and water. The collaboration aims to provide Marinas, Resorts, Glamping and accommodation facilities with vehicles and boats that can give their customers a unique and sustainable experience with 100% electric company vehicles and workboats on the other.

“In recent years there has been an evolution on the different forms of mobility for both vehicles and boats. Today mobility is starting to be perceived as a service and will be more and more so for the future. And we are starting to see this need in boating as well, where there will be fewer owned boats and more boats for tourists and citizens to share,” said Michele Solari, chief marketing officer of Barchelettriche Srl.
Luciano Iengo, chief marketing officer of Koelliker, on the other hand, explained, “This collaboration allows us to be at the side of hospitality facilities with our company vehicles and to propose two micro-mobility solutions for their guests, such as Microlino, the 100% electric and made in Italy microcar, and the Koelliker e-scooter, which are well suited to be protagonists of an increasingly green and smart mobility.”

First carbon motor for e-bikes unveiled

First carbon motor for e-bikes unveiled

Edinamic has launched the EDC1, the first motor for e-bikes in carbon. EDC1 is equipped with a unique powertrain with a patented pedal release mechanism that allows the rider to disengage from assistance. In this way, the bike is simply transformed into a muscle model when the motor is switched off or when the speed exceeds 25 km/h.
Alessandro Campanini, founder and CEO of Edinamic said: “This new concept motor was born after a process of design and testing by the Edinamic staff and responds to a precise purpose defined in our company mission: to create products that, in addition to providing benefits, are also able to give emotions. I imagined the development and evolution that the technology could have”. It was with these assumptions that the first carbon engine was first conceived and then designed.

ABB improves its range of HDP motors

ABB improves its range of HDP motors

ABB has improved its range of High Dynamic Performance (HDP) induction motors, creating new opportunities for machine builders looking for motor and drive solutions with excellent dynamic response and high power density. Typical applications for these motors include plastic and rubber extrusion, injection moulding, winding systems, elevators, conveyors, test benches and machine tools. The improved range allows output powers of up to 2 MW and alternative versions such as high-speed and water-cooled motors. The motors are designed for use with a frequency converter, and ABB can provide the matching motor-drive package for the full range of frame sizes.
The high power density offers advantages for both retrofit and new-build machines, and thanks to their low inertia and high overload capacity, the HDP motors enable fast motion control and high manoeuvring accuracy. “For ABB, ease of installation is a priority and is an integral element of the HDP motor concept. Consequently, a replacement HDP motor is easy to install in a machine already in use without excessive engineering work,” the company explains.

New motor control centre from Rockwell Automation

Rockwell Automation has launched Flexline™ 3500, a new low-voltage motor control centre (MCC) for the global IEC markets. “With this motor control centre, industrial companies can harness production data and increase uptime and productivity with a range of intelligent products,” the company explained. In manufacturing and process activities, every minute of production counts. However, it is estimated that, globally, the average manufacturer faces up to 800 hours of downtime per year. Depending on the industry, downtime can cost $100,000 per hour or more. By integrating with intelligent motor control devices, the Flexline 3500 MCC provides real-time operating data and diagnostics for critical equipment. Manufacturers around the world rank predictive maintenance as the leading strategic technology for reducing downtime.
The modular design of the motor control centre is customisable to suit multiple low-voltage motor control applications as well as factory footprint requirements, while the technology is designed for a wide range of industries, from food to oil & gas. Furthermore, when Flexline 3500 motor control centres are integrated with intelligent variable frequency drives, manufacturers can significantly reduce energy consumption.
