- The mixing of a number of elements 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 might probably 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 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 lately, 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 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 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 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 automobile. It’s all about producing as most of the elements as potential 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 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 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 venture 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 completely different from these of Japanese producers.” This was a delicate manner of claiming they aren’t constructed to the identical customary, however the market doesn’t appear to thoughts, and BYD offered 300,000 Atto 3s within the car’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. The very best 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, despite the fact that this protects prices and cuts complexity, Tesla isn’t eager about pursuing gigacasting additional and making use of it to different fashions, despite the fact that it commissioned and purchased among 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 know-how than advancing car-building methods.
