Engineering challenges in EV high-voltage connections
High-voltage connections are critical to the performance and reliability of electric vehicle (EV) electrical systems. Engineers must consider how connectors handle electrical loads and maintain reliable operation throughout the vehicle’s service life. Higher-voltage architectures also introduce additional requirements for insulation and electromagnetic compatibility. This Q&A brings together six engineering questions, answered with excerpts from previously…
Engineered disorder improves lithium-rich cathode performance
Researchers at Hanbat National University in South Korea have demonstrated that intentionally introducing disorder into lithium-rich cathode materials can improve battery capacity and stability. The approach could help address performance limitations in high-energy-density batteries being developed for electric vehicles (EVs). Lithium-rich cathodes offer the potential for greater energy storage, but their performance can deteriorate when…
Floating board-to-board connectors for EV powertrain electronics
Hirose Electric has expanded its FunctionMAX family with the FX36 Series, a 0.5-mm-pitch floating board-to-board connector designed for use in electric vehicle (EV) powertrain electronics. The series accommodates circuit-board misalignment and vibration in compact systems, including traction inverters and onboard chargers. The connector incorporates a floating mechanism that allows ±0.7 mm of misalignment in the…
Cybersecurity certification covers development processes for connected equipment
SINEXCEL has received IEC 62443-4-1:2018 certification from TÜV SÜD for its product cybersecurity development processes. The certification is relevant to the company’s electric vehicle (EV) charging equipment, where connected systems require security considerations throughout product development and maintenance. IEC 62443-4-1 establishes cybersecurity requirements for the development lifecycle of industrial automation and control system products. The…
Aluminium-intensive EV design could reduce battery capacity by 15%
A joint theoretical study by Alumobility and Stellantis has found that an aluminium-intensive vehicle architecture could reduce battery capacity by 15% while maintaining equivalent driving range. The findings demonstrate how reducing structural weight in a battery-electric vehicle (BEV) can create opportunities to optimize other vehicle systems. Using Stellantis’ STLA Medium platform as a steel-based reference,…
