Tesla Teases Less-Expensive, Next-Gen EV Motor and Platform
Viewers of Tesla’s 2023 Investor Day stream hoping for extra particulars in regards to the upcoming Cybertruck or a glimpse on the rumored Mannequin 2 have been left upset. Nonetheless, the electrical automaker did tease particulars about the way it’s its next-generation car platform and electrical motor, which guarantees to be extra environment friendly and extra inexpensive.
The automaker’s powertrain designers used in-house developed software program to simulate the interplay between the magnetic fields between the stator and rotor, optimizing the fee, weight and measurement and sound of the electrical motor via speedy iterative design. Additionally they labored carefully with Tesla’s manufacturing engineers to make comparable optimizations to the manufacturing course of and supplies.
The brand new drive unit will function a everlasting magnet design, however require no uncommon earth metals.
Now taking part in:
Musk Outlines Imaginative and prescient for Electrical Planes and Boats
Tesla says the next-generation powertrain would require 75% much less silicon carbide to provide, with none compromise to efficiency or effectivity. Regardless of the brand new drive unit being a everlasting magnet design, Tesla additionally says it can require zero uncommon earth supplies. It will be extra production-efficient, requiring 50% much less manufacturing unit flooring house than the Mannequin Y’s motor, and round $1,000 cheaper per unit to provide, which is essential contemplating the autos constructed on this platform are anticipated to be essentially the most inexpensive Tesla EVs but.
The brand new platform can be suitable with any battery chemistry and will make use of new manufacturing strategies to streamline manufacturing. Tesla says that classes it discovered the laborious means through the growth of its oft-delayed Cybertruck impressed it to rethink the custom collection meeting line. Relatively than the car’s unibody chassis shifting down the road as an entire, elements of the brand new mannequin (sides, doorways, flooring, entrance and rear subframes) can be assembled on parallel strains, solely coming collectively on the very finish of the road.
Tesla says this “unboxed course of” is extra environment friendly, cost-effective and much less liable to manufacturing bottlenecks. That final bit is very essential if Tesla desires to hit its purpose of producing 20 million EVs a 12 months by 2030.
Relatively than assembling the car on a single line, element sub-groups can be assembled in parallel earlier than being introduced collectively a lot later.
Along with the high-voltage powertrain, the automaker can be rethinking the low-voltage energy system, redesigning and decreasing the wire harnesses that function the car’s nervous system. It is shifting from 12 volts to a 48-volt structure which (because of Ohm’s regulation) will allow decrease present, smaller wires and elements with smaller warmth sinks, all of which helps save weight. Subsequent, fairly than a fancy community of analog harnesses, Tesla is shifting to a community of smaller controllers — additionally designed and constructed in-house — linked by ethernet to the car’s highly effective central mind. This can drastically cut back the variety of wires snaking across the physique and, because of bidirectional communication, simplify diagnostics and debugging.
Neither Musk nor different Tesla management presenting on the investor day commented on a timeline for the anticipated deployment of the next-generation platform, powertrain or the car that may finally host it.
