The Tesla Cybertruck is provided with an all-new 48-volt low-voltage system, which replaces the outdated however nonetheless the favored, 12-volt system.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 units was confirmed by Tesla in the course of the 2023 Investor Day in March and utilized within the remaining product as promised.

*The principle traction battery system that runs the drive models is a high-voltage one with a nominal voltage of over 800 volts.

The principle profit of upper voltage for auxiliary units is that the identical energy might be equipped at a decrease present, which immediately lowers the present losses and permits the usage of thinner wires to avoid wasting weight and price. Giant autos already have been utilizing 24-volt techniques, however 48-volt continues to be a uncommon answer in automobiles.

Tesla doesn’t intend to cease there by merely shifting from 12 volts to 48 volts for its personal electrical autos. The automaker wish to assist unfold the 48-volt structure by means of the trade.

For this reason Tesla despatched the 48-volt system specs to different producers and Ford CEO Jim Farley simply confirmed that he acquired it.

Contemplating his response “Nice for the trade!” we are able to assume that Ford will probably be keen to implement a 48-volt system in its autos as nicely, 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.

Replace: In a following submit, Jim Farley stated: “Nice to learn the doc and understand that our next-gen group has been on an identical path. Let’s work collectively to assist the provision base transfer into the 48V future as nicely.” This clearly signifies that the next-generation Ford all-electric autos may also have a 48-volt system.

Regardless of many apparent advantages, the automotive trade is typically very gradual to vary the issues that work for one thing higher.

The change from 12 volts to 48 volts is just not so simple as one would suppose, as a result of it requires redesigning automobile wiring and (not less than typically) all new electrical elements (each motor, gentle, sensor, and chip) or not less than guaranteeing that they will function at the next voltage.

The problems are that this requires funding, there aren’t that many suppliers of components and there’s no financial system of scale firstly. The modifications additionally imply that the entire service facilities have to be prepared for the brand new low-voltage system. 

With Tesla’s template of a 48-volt low-voltage system, the remainder of the trade may be keen to develop their very own answer—first, as a result of it will likely be simpler to start out from one thing somewhat than from scratch, and secondly, as a result of now the competitors is one step forward.

Following the primary Tesla Cybertruck deliveries, Munro Stay‘s Sandy Munro had a chance to talk with Elon Musk concerning the 48-volt system and points that prevented such a transfer up to now.

Let’s additionally recall that in new electrical automobiles, 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 change 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 have not seen the Tesla Cybertruck’s auxiliary battery but, and an internet guide 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 kind of battery cells (and from whom) have been used?
