Why Tesla’s move to 48-volt electrical architecture is an industry game changer
Tesla's CyberTruck has been grabbing attention in the auto industry since its unveiling in 2019. It’s cold-rolled stainless steel exoskeleton chassis and innovative manufacturing methods have been generating increasing interest, despite multiple delays in its launch date. The vehicle's fan base is constantly on the lookout for new information, and recent investor day presentations confirmed a long-discussed innovation: its 48-volt electrical architecture.
In the Tesla investor day presentation at the company's Austin headquarters, Pete Bannon, vice president of Low Voltage and Silicon Engineering at Tesla, announced that Tesla power electronics platforms will be moving to 48 volts.
“This reduces the current needed by a factor of four and since power loss in the harness is resistance times the square of the current a 4X reduction and current leads to a 16X reduction in lost power.”, said Bannon.
While 48v systems have been partially utilized for high draw componentry in mild hybrid vehicles for a few years now, the CyberTruck replacement of the traditional 12v power electronics system is a significant step forward for the auto industry. In traditional 12v systems, wiring and components have to be larger and heavier to handle high electrical loads. However, the 48v system can handle these loads more efficiently, which reduces the size and weight of wiring and components.
Tesla's vertical integration, manufacturing capabilities, and corporate structure give them an unprecedented agility to design and produce their own highly integrated components in-house, enabling a swift transition to the 48-volt system. The implementation of this technology starting in the CyberTruck provides several advantages. The 48-volt system enables more efficient power delivery and handling of higher electrical loads with smaller less complex cabling, resulting in lower overall weight and greater efficiency gains.
“The (12v) low voltage harness is built from individual wires cut to length crimped and inserted into connectors a manual
process that is tedious error-prone and
doesn't scale well,” said Bannon
Using a 48v system will likely enable the automated manufacturing of wire looms described in a 2018 patent (US20190217794A1).
In addition to this, the system change further embraces removal for hardware component control systems like relays, fuses, and CANBUS and replaces them with software control over Ethernet.
“Control over all the software which enables us to develop features and functionality that we never even dreamed of at the time we designed the hardware, so that's why you see software in your car is getting better and better over time in ways that we didn't even think of
when we designed the hardware in the first place” said David Lau VP of software engineering at investor day. For example, sentry mode.
Legacy automakers have been slow to fully adopt 48-volt technology partly due to their dependence on third-party suppliers, who may not be equipped to handle a rapid transition to a new system voltage.
In a recent Autoline Daily interview, Sandy Monroe noted that "Everybody had been talking about doing this for 30 years, but they didn't."
In a 2020 interview with powerelectronicsnews.com Patrick Wadden Global VP Automotive Business Development at Vicor Corporation said
“Overcoming the hesitancy to modify the long-standing cost-optimized 12-volt power delivery network (PDN) may be the biggest challenge”.
According to Cory Steuben, President of Monroe and Associates, manufacturers and suppliers will have to switch to 48 volts: "Either the customer will pay, or the car maker will take the profit loss of not adopting 48 volts."
As more automakers recognize the benefits of the 48-volt system, they will be compelled to invest in the necessary technology and infrastructure to make the switch. Failure to do so could result in a loss of market share and profitability. David Lau closed out his contribution to the 48v discussion with an ominously prescient invite;
TSLA retail investor Matthew Donegan-Ryan, spoke with Tesla executives at the investor day and disclosed on twitter
that Tesla has its own "secret" accessories team dedicated to developing products specifically for the 48-volt architecture, such as lighting, winches, and air compressors.

These products are designed to work seamlessly with the CyberTruck systems, offering customers a wide range of high-quality accessories that are tailored to the vehicle's capabilities. With this approach, Tesla not only aims to provide a superior product to its customers but also creates new revenue streams and strengthens its brand image as a leader in innovation and design.
The members of the CyberTruck fan site Cybertruckownersclub.com have been letting their imagination run wild over this development hoping that the 'Secret accessories team' would consider some of their ideas.
Tesla's adoption of a 48-volt electrical architecture in the CyberTruck represents a significant step forward for the auto industry and aligns with the company's mission to accelerate the world's transition to sustainable energy and transport. By designing and
manufacturing their own components in-house, Tesla will be able to seamlessly transition to this innovative technology, which is a distinct advantage in the automotive market.
By taking advantage of the benefits offered by the 48-volt system, such as improved power delivery, handling of higher electrical loads, lower weight, and greater efficiency gains, Tesla is establishing a distinct advantage in the market. The company's "secret" accessories team is dedicated to developing products that work seamlessly with the CyberTruck systems, which not only provides a superior product to customers but also creates new revenue streams and strengthens Tesla's brand image as a leader in innovation and design.
As legacy automakers struggle to adapt to new technologies generally, Tesla's gains with the 48-volt system will serve as a reminder of the importance of vertical integration, innovation in manufacturing capabilities, and corporate structure in the seamless transition to sustainable transportation.
With its continued investment in R&D and CyberTruck as its technology beacon, Tesla is poised to continue leading the way in the electric vehicle industry, playing a key role in the world's transition to a sustainable energy future.
