- The combination of a number of parts right into a single drive unit that BYD calls E-Axle was probably the most spectacular half.
- Between the E-Axle and the economies of scale that BYD can obtain, it could actually 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 world EV chief as of late, 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 dimension and specs. In China, the place it’s referred to as the Yuan Plus, it begins at 139,800 yuan, or simply below $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 optionally available 60.5-kWh battery ups the vary to 317 miles (510 km) for a further 10,000 yuan or $1,400. This bigger pack can be supplied on the European model of the Atto 3, which prices almost 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 that buys the automotive. It’s all about producing as lots of the parts as doable 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 possibly can construct them) goes a great distance towards explaining how these extremely competent Chinese language EVs might be offered at such low costs.
The BYD Atto 3 was chosen for this challenge 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 received.
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 delicate approach of claiming they aren’t constructed to the identical commonplace, however the market doesn’t appear to thoughts, and BYD offered 300,000 Atto 3s within the automobile’s first yr of manufacturing beginning in February 2022—it has been doing fairly effectively in some European markets too.
Tesla has an identical method of mixing a number of parts to cut back prices. The most effective instance is the Mannequin Y’s construction, which consists of simply two main items as an alternative of 70 separate components like within the smaller Mannequin 3. Apparently, regardless that this protects prices and cuts complexity, Tesla isn’t excited by pursuing gigacasting additional and making use of it to different fashions, regardless that it commissioned and bought a number of the world’s most spectacular die-casting presses.
This might be as a result of Tesla’s curiosity has now shifted extra towards self-driving expertise than advancing car-building methods.
