Automation for sustainable mobility The world’s first automated and driverless parking function Damien Kögler Bringing mobility and sustainability together requires systems that protect the environment, are closely interwoven, and provide users with a convenient mobility experience. Automated valet parking and automated valet charging play a key role here. The smart technology for infrastructure-based, automated driving from Bosch takes the hassle out of finding a parking space and also takes over the parking process. But that’s not all: while the vehicle is parked, it is also automatically ch ..read more

New LCP (Xydar® G-330 HH) material for Battery Module Insulation Designed to Mitigate Thermal Runaway, Improve Electrical Insulation, & Provide Space Savings Jiwen Wu, Nicolas Batailley, Brian Baleno Next generation battery electric vehicles (BEVs) are launching with much higher voltages than many of the current 400 Volts systems on the market today. Driven by the need to increase range and enable direct current (DC) fast charging, automotive car makers are introducing battery systems that operate above 800 Volts. The addition of more battery cells as part of the overall battery system is ..read more

EV Battery Design – Innovating for Longer Range and Battery Life Hwee Yng YEO The electric vehicle battery is one of the critical automotive technologies that have successfully scaled to support the e-mobility boom. The average EV battery pack cost $153 / kWh in 2022 – that’s a 90% price drop over a 15-year period. Looking forward, the automotive industry expects demand for Lithium-ion cells to grow by some 33% annually to 4,700 GWh by the end of this decade. More affordable EV batteries will help bring about the price parity between an EV and internal combustion engine car sooner than later ..read more

Revolutionizing Thermal Management in E-Mobility: High-Performance Sealing Solutions Monica Monte In the ever-evolving landscape of electronic mobility (e-mobility), pursuing higher efficiency, extended battery life, and enhanced safety remains paramount. One critical factor that significantly impacts these goals is thermal management. Efficiently dissipating heat generated by electronic components in electric vehicles (EVs) and other e-mobility applications ensures optimal performance and longevity. Schlegel Electronic Materials, a pioneering company at the forefront of sealing solutions, pri ..read more

Testing electromobility professionally Testing Hybrid and Electric Vehicles Klaus Leibold Electrical machines and drive systems place increasingly high demands on measurement and testing technology. Additional mobile and stationary test equipment is usually required in addition to conventional multimeters to ensure the safety of users. Functional and safety checks are absolutely essential, both on electric and hybrid vehicles and on the associated charging infrastructure. Ensuring this is one of the tasks that GOSSEN-METRAWATT has set itself. For years, the company has been working in close co ..read more

New materials and stacking technologies – Cost optimized Cobalt-Iron solutions for high performance electric motors Dr. Robert Brand High performance combined with small size and low weight are key requirements for electric drives. In applications with particularly high-performance demands such as aviation or motorsports, laminations made of cobalt-iron alloys are commonly used. Compared to classic electrical steel, this typically allows 20-30% higher power densities to be achieved. However, a technology transfer to roadgoing vehicles or high-performance industrial applications has rarely been ..read more

Next-generation testing for a safer today and tomorrow Advanced Driver Assistance Systems (ADAS) are standard equipment on electric vehicles, and serve to prevent accidents and make our roads safer. Testing the effectiveness of these systems requires engineering brainpower and robust methodologies to get it right. Product integrity and brand reputations depend on it. Aaron Mandalia The automotive industry is embracing a future that’s electric. The rapid development of Automated, Connected, Electrified and Shared (ACES) technology is changing the transport landscape forever. (Photoshoot 0322-02 ..read more

Martin Søgaard Electric vehicles (EVs) typically use regenerative braking, where the electric motor generates electricity that is stored in the battery. However, there are several brake conditions under which regenerative braking may not be an option (i.e., at low speeds, at speeds where deceleration is above a certain threshold value, and during emergency braking). Consequently, EVs are also equipped with traditional means of braking, typically disc brakes or drum brakes. As EVs carry a heavy battery, disc brakes are often chosen due to superior braking performance over drum brakes. Efforts t ..read more

New components for electromobility require novel manufacturing strategies According to expert estimates, by 2040 almost 45 percent of all passenger cars sold worldwide will have a battery or fuel cell drive system. This will result in a large number of new systems and components in production. This also poses a challenge to the supplier industry. Dr. Axel Luft Automobile manufacturers worldwide are working to reduce emissions. According to a 2022 study by the German industry association VDMA and FEV Consulting GmbH, almost 45 percent of a total of 128 million passenger cars sold worldwide will ..read more
