- The mixing of a number of parts right into a single drive unit that BYD calls E-Axle was essentially the most spectacular half.
- Between the E-Axle and the economies of scale that BYD can obtain, it will possibly promote its EVs at very inexpensive costs that non-Chinese language automakers merely cannot match.
Japan was a world chief in electrical and electrified autos within the early 2000s, however its lead has since subsided, and it lags behind most developed nations on this regard. China is the undisputed international EV chief nowadays, and the Central Japan Financial and Commerce Bureau organized a seminar that concerned the teardown of a number of EVs to see how others are already so superior.
In accordance with Nikkei, the BYD Atto 3 (pictured) impressed attendees with how inexpensive it’s given its measurement and specs. In China, the place it’s referred to as the Yuan Plus, it begins at 139,800 yuan, or simply beneath $20,000, and for that, you get a 201 horsepower EV with a 50-kilowatt-hour battery that offers it a claimed CLTC vary of 267 miles (430 km).

The bigger elective 60.5-kWh battery ups the vary to 317 miles (510 km) for an extra 10,000 yuan or $1,400. This bigger pack can also be supplied on the European model of the Atto 3, which prices practically twice as a lot because it does in China. The upper worth is the results of each markup and import tariffs, that are set to rise beginning subsequent month.
The Atto 3 teardown in Japan revealed one of many methods BYD manages to maintain prices down and go the financial savings right down to the one who buys the automotive. It’s all about producing as lots of the parts as attainable in-house and integrating them. The supply article highlights the so-called “E-Axle” utilized by BYD, which is comprised of eight totally different parts.
It consists of not solely the motor, inverter, transmission and controller but in addition the onboard AC charger, the DC-to-DC converter and the battery monitoring system (BMS). This method, mixed with the economies of scale (the bigger the variety of automobiles you construct, the cheaper you’ll be able to construct them) goes a good distance towards explaining how these extremely competent Chinese language EVs will be bought at such low costs.
The BYD Atto 3 was chosen for this undertaking not solely due to its worldwide success but in addition as a result of it ranked very extremely within the 2023 Japan EV of the Yr awards and one other BYD mannequin gained.
Kenichi Ito, director of commercial equipment firm Sanyo Buying and selling and one of many seminar organizers, famous that “Chinese language producers connect nice significance to low-cost manufacturing” and “their views on high quality are totally different from these of Japanese producers.” This was a refined means of claiming they don’t seem to be constructed to the identical commonplace, however the market doesn’t appear to thoughts, and BYD bought 300,000 Atto 3s within the automobile’s first 12 months of manufacturing beginning in February 2022—it has been doing fairly nicely in some European markets too.
Tesla has an analogous method of mixing a number of parts to scale back prices. The most effective instance is the Mannequin Y’s construction, which consists of simply two main items as a substitute of 70 separate parts like within the smaller Mannequin 3. Apparently, despite the fact that this protects prices and cuts complexity, Tesla isn’t thinking about pursuing gigacasting additional and making use of it to different fashions, despite the fact that it commissioned and bought a few of the world’s most spectacular die-casting presses.
This could possibly be as a result of Tesla’s curiosity has now shifted extra towards self-driving expertise than advancing car-building strategies.
