A new analysis conducted in Sweden, examining nearly 10,000 electric vehicles, has pinpointed two specific models that demonstrate exceptional battery health. These vehicles retained over 97% of their original capacity after accruing 62,000 miles on the road, suggesting impressive durability in real-world conditions.
Webasto has introduced the 900 EX Power Bridge, an innovation allowing laboratories to increase the voltage capacity of their existing 900 EX battery test units. This new technology combines two test units into a single system, achieving a robust 1,500 V and 500 kW rating without requiring new hardware purchases. It's designed to streamline high-voltage battery development and validation processes.
Ensuring the safety of electric vehicles, from battery packs to charging systems, relies heavily on rigorous high-potential (hipot) testing. This diagnostic procedure verifies the integrity of electrical insulation, preventing potential hazards from the high voltages and currents present in EVs. Employing sophisticated components like reed relays enhances the precision and reliability of these essential safety checks.
Chinese manufacturer FAW Jiefang is actively testing sodium-ion batteries in its heavy-duty trucks, marking a significant step from lab development to real-world application. This initiative aims to assess the practicality and performance of these more affordable and abundant battery alternatives for commercial vehicle use, potentially reducing reliance on lithium-ion technology.
