Rivian already has a patent on Tesla’s Cybertruck ‘range extender’
Tesla delivered the first Cybertrucks yesterday, and with that delivery event came the revelation that in order to get the range it promised, the Cybertruck needs a separate battery pack in the bed. But a similar battery pack system was already patented years ago, by one of Tesla’s competitors in the electric pick-up space.
Tesla’s Cybertruck website included a revelation about a feature that wasn’t mentioned in its presentation: a “range extender,” in the form of an additional battery pack in the truck bed which expands the truck’s range.
It’s an interesting solution, and we don’t know all the details of it yet. We don’t know the cost, the weight, how it will be installed and uninstalled, or whether it even can be uninstalled.
The battery pack is intended to be used “for very long trips or towing heavy things up mountains,” according to Tesla CEO Elon Musk. It takes up about a third of the truck bed, as can be seen in a photo posted on Tesla’s Cybertruck site.
So, there’s still room for cargo, just not the full 6 feet of bed length that Tesla says the Cybertruck has.
But the fact that it was described as being used only “for very long trips or towing heavy things up mountains” suggests that it will be removable, since most people don’t do that sort of thing every single day.
Making it removable is actually a good solution, because it can lower prices, make packaging easier, and improve efficiency for vehicles that simply don’t need a ridiculously enormous 470-mile battery – and most drivers don’t need that.
And if it is removable, well, there’s already a patent on that.
In 2019, electric truck maker Rivian filed a patent for a “removable auxiliary battery” that would fit into the front third-or-so of the truck bed. This patent was granted in 2020, so Rivian currently has a patent on this technology.
The patent is described as:
An electric vehicle system for transporting human passengers or cargo includes an electric vehicle that includes a body, a plurality of wheels, a cargo area, an electric motor for propelling the electric vehicle, and a primary battery for providing electrical power to the electric motor for propelling the electric vehicle. An auxiliary battery module is attachable to the electric vehicle for providing electrical power to the electric motor via a first electrical connector at the auxiliary battery module and a second electrical connector at the electric vehicle that mates with the first electrical connector. The auxiliary battery module can be positioned in the cargo area while supplying power to the electric motor, and can be removable and reattachable from the electric vehicle. The auxiliary battery module includes an integrated cooling system for cooling itself during operation of the electric vehicle including a conduit therein for circulating coolant.
We aren’t patent lawyers here, but this sounds awfully similar to Tesla’s “range extender.” The obvious potential differences we can find are if the range extender doesn’t have integrated cooling, which is unlikely, or if the range extender isn’t removable, which doesn’t seem to jive with the statement that it is only for long trips or with the marketing showing it as an optional add-on (if that were the case, why not just offer different battery sizes?).
Tesla itself has many patents (and is still pursuing more of them), but has pledged not to “initiate patent lawsuits against anyone who, in good faith, wants to use its technology.” It announced this in a 2014 blog post, and followed up by saying that it thinks several companies are using its patents.
So next, the question is: is Tesla’s solution different enough to avoid Rivian’s patent protection? Has Tesla licensed the idea from Rivian, and we just haven’t heard about it yet? Or will Rivian return Tesla’s “good faith” and not initiate a patent lawsuit against Tesla, if it does feel like it has a good enough case to say that Tesla’s range extender infringes on its patent?

The first EV charging hub funded by the Charging and Fueling Infrastructure (CFI) Program in the Eastern US is now online in Deerfield, Massachusetts.
The town installed the region’s first DC fast chargers (four ports), along with four Level 2 chargers, at 59 North Main Street in South Deerfield.
These new charging stations, funded with $2.46 million from the CFI program, are conveniently located near Interstate 91 in Franklin County, the most rural county in Massachusetts, which serves drivers from Connecticut up to the Canadian border.
The hub also features local and regional bus stops and designated bike lanes with secure onsite bike racks. The chargers are meant to cater to everyone: from local residents and visitors to municipal EVs and commercial vehicles that service the region’s businesses, like those in food and beverage manufacturing.
Gabe Klein, executive director of the Joint Office of Energy and Transportation, sees this as a model for future projects:
Multi-modal charging hubs in communities are key to giving more people the choice to ride and drive electric. The Town of Deerfield is showing leadership in building out convenient charging infrastructure that brings new transportation choices to rural and disadvantaged communities while supporting local commerce.
In recent years, Deerfield has experienced increased climate change-driven flooding from nearby rivers, including the Deerfield River, the Connecticut River, and the Bloody Brook. The project incorporates environmental engineering designed to mitigate and adapt to the effects of flooding and climate, including the installation of permeable asphalt and rain gardens, planting of native trees, grasses, and shrubs, and the creation of new greenspace in the center of Deerfield.
The Biden-Harris administration’s CFI Grant Program is expanding EV infrastructure nationwide. It offers grants for projects that complement and expand upon the initiatives of the NEVI program in urban, rural, and disadvantaged and low-income communities. So far, the CFI Grant Program has allocated over $1 billion to nearly 100 projects across the US, encouraging private investments and expanding the EV charging network to make EV ownership more practical and convenient.

Kia’s upcoming EV4 electric sedan was just spotted testing in the US for the first time. The low-cost EV is expected to make its big debut by the end of the year. Here’s a look at the new model.
The EV4 will round out Kia’s new “EVs for all” master plan launched last year. Kia showcased three new models, the EV3, EV4, and EV5, during its first annual EV Day in October 2023.
During the event, Kia outlined its new global strategy to “lead and accelerate the EV revolution” with a wide range of models priced from $30,000 to $80,000.
Kia plans to rapidly expand its lineup with a series of smaller, lower-priced models. It launched the EV9, its first three-row electric SUV, which is already proving to be a hot seller in the US. Starting at under $55,000, the EV9 is still a great deal compared to others in its class, but Kia plans to go even lower.
The EV3 and EV4 are expected to be among the most affordable electric vehicles when they arrive in the US.
Kia’s new EV4 is now testing in the US
Ahead of its official debut, Kia’s new EV4 sedan was recently caught driving on US streets for the first time.
The latest image from KindelAuto doesn’t reveal much more than what’s been shown in the past, but the fact that it’s now testing in the US is significant.
Kia’s EV3 is already on sale in Korea, starting at around $30,000 (42.08 million won). Earlier this week, the company said its new compact SUV is now available across Europe, starting at around $38,000 (36,000 euros) with a “segment-leading range” of up to 375 miles (WLTP).
Next up will be the EV4. Kia is expected to officially reveal the new EV by the end of the year, with deliveries starting in 2025. It could be as soon as next week at the 2024 LA Auto Show.
The interior will feature Kia’s advanced new ccNC infotainment system with dual 12.3″ navigation and driver display screens. An otherwise minalimalistic design is expected inside.
Kia’s EV4 will also be available in a hatchback variant. Although the hatch is likely aimed at European buyers, it was also recently spotted testing in the US for the first time.
We will learn official prices closer to launch, but the EV4 is expected to start at around $35,000 to $40,000.
Kia is teasing five new vehicles for the US, at least one being a new EV, that will debut at the LA Auto Show next week. Will it be the EV3? EV4?
