Summary
The Automotive Engineering Exposition 2025 was held from May 21 to May 23, at the Pacifico Yokohama convention and exhibition center.
This year, the number of exhibitors increased from last year's 590 companies (1,378 booths) to 617 companies (approximately 1,470 booths). According to an announcement by the organizer, the Society of Automotive Engineers of Japan (JSAE), the total number of visitors registered for the three-day event was 79,808, up from last year’s 75,972, and the venue was quite crowded at certain times of the day.
This report introduces inverters, thermal management components, power electronics components, e-Axle and motor components, bearings, and countermeasures for electrolytic corrosion.
