The Central Bureau of Economy, Trade and Industry of Japan held a workshop on October 7 to share trends in electric vehicle (EV) technology. About 70 auto parts companies in central Japan visited the EV teardown exhibition facility and learned about the body structure and component design features of Chinese-made EVs. As a backdrop to the production of low-cost EVs by Chinese companies, the generalization and in-house production of parts have emerged.
- Japanese disassemble Chinese cars and are surprised by the BYD Yuan Plus
- More than 90,000 parts from 16 models, including BYD's ATTO3 SUV (Yuan PLUS in China), the ET5 from Shanghai NIO, and Tesla's Model Y from United States, were on display.
- One of the EVs that attracted the attention of participants was BYD's ATTO3. The car went on sale in China in February 2022 with prices starting at around 140,000 yuan. Global sales will reach 300,000 units as of March 2023.
- One of the features of ATTO3 is the integration of advancing components. The E-Axle electric drive unit has a total of eight components, including a motor, inverter, and reducer, as well as an on-board charger and a DC-DC converter (DC voltage converter). As a result, component costs can be reduced, and weight can be reduced.
- In addition, BYD is promoting the sharing of parts with other models for the ATTO3 and in-house production. Taking advantage of the high sales volume of EVs, the cost of parts has been reduced through mass production.
- However, there are also some designs that are not perfect, and many people think that the waterproof performance of the car battery is not sufficient.

was surprised by the small number of parts produced by BYD and Tesla. Our company also wants to use the experience of our existing business to enter the EV field

The EV teardown exhibition facility opened in March 2022.
So far, more than 6,000 people from 450 companies have visited. The contents of the exhibition are updated regularly, and four new models are planned to be added by the end of October, including the L9 from Li Auto, an emerging EV manufacturer in China, and the IONIQ 6 from Hyundai Motor in Korea.
In the central region of Japan, Toyota Tsusho also operates Toyotsu Manabu Square (Miyoshi City, Aichi Prefecture), a teardown and exhibition facility for gasoline vehicles and EVs. Parts of Toyota's Vitz and bZ4X are available to partners and other partners free of charge.
