Tesla confirms Model 3 battery pack uses 2170 form factor cells

Published

on

Tesla has confirmed through its 2017 Second Quarter Update Letter that Model 3 is using the company’s high energy density 2170 cells in its battery pack. This confirmation puts to rest previous speculation that Tesla was producing a lithium ion cell with a much larger form factor specifically for Model 3.

Tesla had begun mass production of its 2170 form factor cells earlier in the year for use in its line of commercial and home energy storage solutions – Powerpack and Powerwall. The company confirmed today that Model 3 battery packs will also be sharing the same lithium ion cell type, however built on a new production line at the Gigafactory facility outside of Reno, Nevada.

“Model 3 drive units as well as battery packs made with our proprietary 2170 form factor cells are being built on new lines at Gigafactory 1. We are now fine-tuning these manufacturing lines to significantly increase the production rate.” said Tesla in its update letter.

Tesla’s proprietary 2170 cells, produced in conjunction with partner Panasonic, replaces the more common 18650 form factor cells that’s currently being used in the Model S and Model X battery packs. Tesla CTO JB Straubel noted earlier in the year that the 2170 cells were designed from the ground up to be the optimal in size and energy density for electric vehicles, balancing energy storage with external surface area to allow for sufficient cooling.

Though one might assume that future Model S and Model X refreshes may also include a battery pack upgrade in the form of newer 2170 cells and similar to Model 3’s battery pack, Tesla CEO Elon Musk indicated that there’s no such plans. “No plans to change cell form factor for X and S” said Musk in a tweet posted in June.

The decision to maintain two types of battery cells might have something to do with being able to maintain production and supply chain efficiency. With commodity 18650 form factor cells readily available and production lines for Model S and X well established at the Fremont factory, creating new production lines as they did with Model 3, and reworking the factory to accommodate a different Model S and Model X battery specification is likely something that might take place down the road. For now, disruption to an already well-established supply chain would arguably provide little value to the company and, let’s not forget, Wall Street.

Tesla Energy has become the undisputed dark horse of the electric vehicle maker. This was highlighted by Tesla Energy’s growing role in the company’s overall operations in the past quarters. 

And as per Tesla’s year-end milestone posts on X, Tesla Energy had a blockbuster 2024.

Tesla Energy’s 2024 milestones:

  • As per Tesla on its official social media account on X, the company has hit over 800,000 Powerwalls installed worldwide. 
  • From this number, over 100,000 Powerwall batteries have been enrolled in virtual power plant (VPP) programs.
  • The Powerwall 3 has officially been launched in the United States, Canada, Puerto Rico, the U.K., Germany, Italy, Australia, and New Zealand.
  • The Tesla Megapack hit over 22 GWh in operation across more than 60 countries across the globe.
  • The Lathrop Megafactory, which produces the Megapack, has been ramped to 40 GWh per year. 
  • The Lathrop Megafactory has also produced its 10,000th Megapack battery.
  • The Shanghai Megafactory was completed in just seven months, and it is ready to start Megapack production in Q1 2025.

Powerwall owners’ 2024 impact:

  • As per Tesla Energy, Powerwall owners generated a total of 4.5 TWh of solar energy globally in 2024. This was equivalent to powering a Model 3 for more than 17 billion miles.
  • A total of 1.1 TWh of energy was stored in Powerwalls in 2024. This protected homes from over 5.8 million outages during the year.
  • Tesla’s Storm Watch feature for Powerwall batteries covered 2.8 million severe weather events over the year.
  • Powerwall owners saw collective savings of over $800 million on utility bills.
  • Virtual Power Plants contributed over 2.2 GWh of power to the grid. This reduced the need for 2,200 metric tons of fossil fuel peaker plant emissions.

Utah’s rPlus Energies breaks ground on Tesla Megapack battery system

Utah-based rPlus Energies recently held the groundbreaking ceremony for the Green River Energy Center, a 400 MW solar PV and 400 MW/1,600 MWh battery storage project in Eastern Utah. Tesla Megapacks will be used as the upcoming facility’s battery storage solution. 

At 400 MW/1,600 MWh, the Green River Energy Center is expected to become one of the largest solar-plus-storage projects under development in the United States. Once operational, the facility would supply power to PacifiCorp under a power purchase agreement, as noted in a press release

Utah Gov. Spencer Cox shared his excitement for the project during the Green River Energy Center’s groundbreaking event. As per the Utah Governor, the solar and battery storage system represents a notable step forward for the state’s sustainable energy efforts. 

“This project is being built in rural Utah, by rural Utahns, and for all of Utah. When rural Utah thrives, the entire state prospers. Today, we’re not just breaking ground—we’re building a future of affordable, abundant energy in Utah,” the official noted. 

The Green River Energy Center secured over $1 billion in construction debt financing earlier this year. The facility is also expected to create about 500 jobs, many of which will be filled by local workers. With this in mind, the solar and battery farm would likely prove to be a boost to Emery County’s economy, enhancing tax revenue, strengthening public services, and offering long-term employment opportunities for the area’s residents. 

Sundt Construction will serve as the project’s contractor, EliTe Solar will supply the solar modules, and Tesla will provide the battery storage system for the project. Luigi Resta, President and CEO of rPlus Energies, noted that the Green River Energy Center is special because of the entities that have worked together to make the facility a reality. 

“It’s the partners that make this project special, that have made this monumental project possible. From our equipment providers to the onsite talent, and the support of the local and regional community, we owe this project’s success to each of you,” he stated.

Tesla Energy loses director who brought Autobidder

Tesla Energy is losing a director who brought Autobidder, a real-time trading and control platform that provides value-based asset management and portfolio optimization, to the company.

Rohan Ma, who has been at Tesla for just under eight years, announced he would depart the company on LinkedIn, aiming to take on a new opportunity elsewhere.

Ma posted:

“After eight years at Tesla, this will be my last week. It was a ride of a lifetime! Today, Tesla Energy is thriving and I can confidently say it’s in the best position it has ever been in to drive impact toward the original mission I signed up for. I’m proud to have contributed over the years to where it is now, and will be cheering the team on from the sidelines as they carry the torch forward and continue to relentlessly solve problems at the frontier of the energy transition.”

Ma started as the Senior Manager of Energy Optimization at Tesla back in November 2016. After four-and-a-half years at the position, he then moved on to a new role as the Director of Energy and Software Optimization. He has been in that role for over three years.

The exit of Ma is the latest in Tesla’s tough year in terms of losing high-level employees.

Earlier this year, as a part of widespread layoffs, Tesla eliminated up to 20 percent of its workforce and people like Rebecca Tinucci, who was the company’s Senior Director of EV Charging.

Tesla also lost Rohan Patel, Vice President of Global Public Policy and Business Development, and Martin Viecha, who was Head of Investor Relations, are just a few notables to depart.

Autobidder

Tesla’s Autobidder platform helps owners and operators make money by autonomously monetizing battery assets. It is a real-time trading and control platform that maximizes revenue according to business objectives and risk preferences.

Autobidder already has hundreds of megawatt-hours under management and continues to scale. It is hosted on Tesla’s secure cloud infrastructure that is engineered to handle large and complex computations.

Without Ma’s expertise, Autobidder would likely not be involved in Tesla’s Energy division at all, and although it is not frequently discussed, it is still a major part of the business’s growth over the past several years.
