- The mixing of a number of elements 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 might promote its EVs at very inexpensive costs that non-Chinese language automakers merely cannot match.
Japan was once a world chief in electrical and electrified automobiles 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 keeping 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 known as the Yuan Plus, it begins at 139,800 yuan, or simply underneath $20,000, and for that, you get a 201 horsepower EV with a 50-kilowatt-hour battery that provides it a claimed CLTC vary of 267 miles (430 km).

The bigger non-obligatory 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 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 value 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 cross the financial savings all the way down to the one that buys the automotive. It’s all about producing as most of the elements as doable in-house and integrating them. The supply article highlights the so-called “E-Axle” utilized by BYD, which is comprised of eight completely different elements.
It contains 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 could be offered 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 received.
Kenichi Ito, director of business 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 completely different from these of Japanese producers.” This was a delicate means of claiming they don’t seem to be constructed to the identical normal, 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 properly in some European markets too.
Tesla has an identical method of mixing a number of elements to scale back prices. One of the best instance is the Mannequin Y’s construction, which consists of simply two main items as a substitute of 70 separate components like within the smaller Mannequin 3. Curiously, though this protects prices and cuts complexity, Tesla isn’t interested by pursuing gigacasting additional and making use of it to different fashions, though it commissioned and bought a number of the world’s most spectacular die-casting presses.
This may very well be as a result of Tesla’s curiosity has now shifted extra towards self-driving expertise than advancing car-building methods.
