The Tesla Cybertruck is provided with an all-new 48-volt low-voltage system, which replaces the outdated however nonetheless the favored, 12-volt system.
This transfer from 12- to 48 volts for auxiliary onboard gadgets was confirmed by Tesla in the course of the 2023 Investor Day in March and utilized within the remaining product as promised.
*The primary traction battery system that runs the drive models is a high-voltage one with a nominal voltage of over 800 volts.
The primary profit of upper voltage for auxiliary gadgets is that the identical energy will be equipped at a decrease present, which straight lowers the present losses and permits the usage of thinner wires to save lots of weight and value. Giant autos already have been utilizing 24-volt techniques, however 48-volt continues to be a uncommon resolution in vehicles.
Tesla doesn’t intend to cease there by merely transferring from 12 volts to 48 volts for its personal electrical autos. The automaker wish to assist unfold the 48-volt structure by way of the business.
This is the reason Tesla despatched the 48-volt system specs to different producers and Ford CEO Jim Farley simply confirmed that he obtained it.
Contemplating his response “Nice for the business!” we are able to assume that Ford can be keen to implement a 48-volt system in its autos as properly, doubtlessly beginning with some next-generation all-electric autos.
Tesla CEO Elon Musk additionally responded, “You are welcome.” Maybe we’ll quickly see another producers trace at 48 volts now.
Regardless of many apparent advantages, the automotive business is usually very gradual to vary the issues that work for one thing higher.
The swap from 12 volts to 48 volts isn’t so simple as one would assume, as a result of it requires redesigning automobile wiring and (no less than usually) all new electrical parts (each motor, gentle, sensor, and chip) or no less than making certain that they’ll function at a better voltage.
The problems are that this requires funding, there aren’t that many suppliers of elements and there’s no economic system of scale at the start. The modifications additionally imply that the entire service facilities should be prepared for the brand new low-voltage system.
With Tesla’s template of a 48-volt low-voltage system, the remainder of the business may be keen to develop their very own resolution—first, as a result of will probably be simpler to start out from one thing moderately than from scratch, and secondly, as a result of now the competitors is one step forward.
Following the primary Tesla Cybertruck deliveries, Munro Reside’s Sandy Munro had a possibility to talk with Elon Musk in regards to the 48-volt system and points that prevented such a transfer previously.
Let’s additionally recall that in new electrical vehicles, Tesla nonetheless makes use of a 12-volt low-voltage system, however already managed to modify from the everyday lead-acid auxiliary batteries to 12-volt lithium-ion auxiliary batteries. The swap was introduced in February 2021, and initially launched within the refreshed Tesla Mannequin S/Mannequin X (beginning with the Plaid) – see an in-depth teardown right here – and later used additionally within the Mannequin 3/Mannequin Y (in late 2021).
We’ve not seen the Tesla Cybertruck’s auxiliary battery but, and an internet handbook has not but been launched however we assume that the brand new 48-volt battery within the Tesla Cybertruck can be a lithium-ion battery. The query is what sort of battery cells (and from whom) have been used?
