Tesla Cybertruck: The Breakthrough in 48-Volt Electrical Architecture
Introduction
The Tesla Cybertruck has revolutionized the automotive industry with its unique design and groundbreaking features. One of the most significant design decisions made by Tesla is the use of a low power side running on 48 volts. This departure from the industry standard has caught the attention of other auto CEOs, including Ford’s CEO, who recently confirmed that Tesla has shared instructions on how to implement this technology.
The Advantages of a 48-Volt System
The adoption of a 48-volt electrical architecture has the potential to bring about a similar shift in the industry as the introduction of the Model S did for electric vehicles. By using a 48-volt system, automakers can reduce material costs, specifically copper, and consequently reduce the overall weight of the vehicle. This is evident in the Cybertruck, which weighs less than its competitors despite its larger size, such as the Rivian R1T.
Tesla’s Instructions to Automakers
In a video review of the Cybertruck, automotive journalist Jason Cammisa revealed that Tesla had sent a document titled “How To Build A 48v Vehicle” to every automotive CEO. This document outlines the necessary steps to implement the 48-volt system. Jim Farley, CEO of Ford, confirmed the existence of this document and expressed gratitude towards Elon Musk for sharing this valuable information. Musk responded with a simple “You’re welcome” on his X platform.
The Challenges and Potential Solutions
While the concept of a 48-volt vehicle has been considered by automakers in the past, the main challenge has been the lack of suppliers manufacturing components for 48-volt systems. Both automakers and suppliers were hesitant to invest in the transition to 48-volt components due to the associated costs. However, Tesla, as a company that controls much of its production, took the initiative and successfully implemented the 48-volt system.
The Benefits Beyond Weight Reduction
Aside from the weight and material savings, a 48-volt system allows for higher current flow within the vehicle. This increased power capacity enables the integration of more electric components, including advanced features like the steer-by-wire system found in the Cybertruck. This system, a first in a production vehicle, requires triple the current that an average house could handle in the 1970s. As vehicles continue to incorporate more electric components, the demand for higher power capabilities will likely increase.
The Future of 48-Volt Systems
With Tesla leading the way, it is expected that other automakers will follow suit and adopt the 48-volt electrical architecture in their future vehicles. As the industry continues to evolve and prioritize electric technologies, the advantages of a 48-volt system become increasingly apparent. The Tesla Cybertruck has set a new standard for innovation, and its impact on the automotive industry is likely to be felt for years to come.
