Summary

The Nissan LEAF, the world’s best-selling EV, is often the subject of benchmark surveys. Co-sponsored by Shizuoka prefecture’s Economy and Industry Department and the Hamamatsu Agency for Industrial Innovation’s Next-Generation Automotive Center, the 2017MY LEAF was disassembled for teardown analysis and used for training activities conducted for participating member companies in Shizuoka Prefecture. As part of the same initiative, the 2010MY LEAF was previously disassembled for teardown analysis.

This report summarizes the coverage on the vehicle tear-down training session for the 2017MY LEAF conducted at the Hamamatsu Industrial Technical Assistance Center on July 11, 2019 as well as an introduction of the organizer's approach to EV research, and the difference between the air conditioning systems of the MY2010 and MY2017 LEAF models.
