The 'Next-Generation Vehicle Center Hamamatsu' of the Hamamatsu Agency for Innovation (Shizuoka Prefecture) conducts "components benchmarking activities" as one of its support measures for member companies that are developing components related to next-generation vehicles. By disassembling electric powertrain components and displaying them in the parts benchmarking room, participating member companies, mainly small and medium-sized automobile-related parts manufacturers, can acquire knowledge of the basic structure and parts required to manufacture prototypes of components that will be installed in next-generation automobiles instead of conventional automobile parts.
This report outlines the content of the presentation "Comparison of E-Axles (Electric Powertrains)" given by Mr. Eiji Mochizuki, Director of the Next Generation Vehicle Center Hamamatsu, in the third session of the "Motors and Electric Vehicles" web seminar series, held on November 18, 2021.
The presentation began with an introduction of the activities of the Next Generation Vehicle Center Hamamatsu, followed by an overview of the Jaguar I-PACE, BMW i3, Tesla Model S and Model 3, VW e-Golf, Nissan Leaf, and Audi e-tron, all of which were subjected to teardown analysis. He then explained the features of the motors, reduction gears, and inverters that make up the electric powertrains of the seven models.
