Liquid-cooled charging – a dynamic rapid-charging solution that can help accelerate the electrification of medium and heavy-duty vehicles Jussi Vanhanen Electric medium and heavy-duty vehicles such as trucks and buses demand more charging power than personal EVs. They also have different charging requirements, meaning that they require separate infrastructure investments from light-duty cars. However, there is currently a lack of industry consensus on the standards for the megawatt charging systems medium and heavy-duty EVs need. Kempower S-Series charging satellite system We recently launched ..read more

On the road to a greener future with composite materials Francis Arthur Composite materials have significant potential in the transportation industry, making it possible to create lighter parts for cars, trains and aircrafts but, until recently, the cost and time often associated with composite material production has made high-volume manufacturing of composites unsuitable for many industries. This article discusses an automated manufacturing process that makes it possible to produce these lightweight materials on a large scale, reducing vehicle weight and, therefore, fuel and energy usage, co ..read more

Reducing OEM Financial Risk by Preventing Battery Fires in Electric Vehicles – An Overview of Battery Safety Methods Dr. Kai-Philipp Kairies Batteries are at the heart of our energy and mobility future. If the recent supply chain crunch has shown us anything, it’s that batteries are even more successful than the most optimistic analyst predictions just a few years ago. But with the success of batteries and ever-increasing numbers of deployed battery packs around the world, we also see more incidents of failing systems – from burning electric scooters in apartment buildings in New York City to ..read more

The Devil Is In The Detail! A Closer Look at a Multiphysics Fuel Cell Electric Bus Model Mike Dempsey Much has been made recently about the importance of using virtual models in delivering eMobility. Benefits are often talked about in general and holistic terms; reduction of prototypes, digital twins, model-based design and so forth. As one can easily imagine, the accuracy of a model directly influences its usefulness. After all, you need to trust what the model is telling you in place of real-world testing. But how does a model achieve that realism? What is the importance of detail and fideli ..read more

Battery Management System Testing & Its Challenges  Kiriakos Athanasas, & Anita Athanasas, A battery of an electric vehicle usually consists of about 96 to 200 cells per pack, which are monitored and controlled by a battery management system (BMS). If cells get overcharged, deep discharged, exposed to very high or low temperatures or have chemical issues, the whole battery would be no longer useable. Thus, the battery is only as good as the weakest link in the chain, which means the weakest battery cell. One of the main challenges are the cell voltages, which drift apart because o ..read more
