In a recent publication in the journal “Transportation Engineering,” lead author Y. Xu from Zeekr Technology Europe AB and Chalmers University of Technology has shed light on an innovative approach to enhancing the efficiency of electric vehicle powertrains, particularly through what’s known as torque modulation. This technique, which involves alternating the driver’s torque demand between zero and a set value, could have significant implications not only for electric vehicles but also for the maritime sector as it looks to adopt similar technologies.
Battery Electric Vehicles (BEVs) often struggle with energy efficiency when operating under low-torque conditions. Xu’s research aims to tackle this issue by proposing optimal modulation strategies tailored for both single and dual motor powertrains. The findings suggest that implementing these strategies can lead to notable improvements in powertrain efficiency while also ensuring that driver comfort and vehicle durability are not compromised. “The proposed optimal modulation strategies can enhance powertrain efficiency while maintaining acceptable levels of driver comfort and powertrain durability,” Xu notes.
This research opens the door to exciting commercial opportunities, especially in the maritime industry, where electric propulsion systems are gaining traction. As vessels increasingly turn to electric and hybrid technologies, the principles of torque modulation could be adapted to improve energy efficiency in marine powertrains. This could mean longer voyages on a single charge, reduced operational costs, and a smaller carbon footprint, aligning with global sustainability goals.
Moreover, the study highlights that dual motor powertrains, which are becoming more common in both automotive and marine applications, could benefit significantly from complementary modulation and torque distribution. This approach not only enhances energy savings but also minimizes the impact on comfort—an essential factor for passenger vessels and luxury yachts.
As the maritime sector continues to evolve with electrification, the insights provided by Xu and his team could be instrumental in guiding engineers and manufacturers towards more efficient designs. The focus on mitigating energy losses while ensuring a smooth operation could lead to a new wave of electric vessels that are not only environmentally friendly but also commercially viable. With the maritime industry facing increasing pressure to innovate, research like this could pave the way for a more sustainable future.
In summary, the work published in “Transportation Engineering” by Y. Xu and his colleagues offers valuable insights that could translate well into the maritime domain, presenting a promising avenue for enhancing powertrain efficiency in electric vessels. As the industry navigates through these transformative times, embracing such advancements may very well be the key to staying ahead in a competitive market.
