Tesla patent hints at more reliable batteries through ‘dynamic’ management system
It is no exaggeration to state that Tesla’s business hinges on its battery technology. Fortunately for the company, its batteries are among the best in the industry today. This is particularly notable in the case of Tesla’s electric cars, as well as its energy storage products. In terms of vehicles, Tesla’s battery tech has reached a point where it is capable of supporting the demands of closed circuit driving, as is the case with the Model 3 Performance’s Track Mode. In terms of battery storage, the quality and performance of Tesla’s batteries have been so impressive in South Australia that it appears to have started an energy storage movement.
Considering Tesla’s reputation for never staying still, though, it is almost certain that the company’s batteries will improve over time. This was mentioned by Tesla’s President of Automotive Jerome Guillen to CNBC last November, when he noted that the company’s technology consistently evolves. In his segment, the executive noted that “the design of the (battery) cell is not frozen,” indicating upcoming improvements in the near future.
A recently published patent points to one of these battery tech improvements. Titled “Multi-Channel and Bi-Directional Battery Management System,” the patent describes a way for Tesla to push the envelope on its battery management system even further. In the patent’s description, Tesla noted that the increasing demand for battery-based power is putting an emphasis on the performance demands of management systems, which ensure proper operation within a range of products like electric vehicles and energy storage units.
While battery management systems perform vital functions, the units themselves could be subject to various external factors. In the case of electric cars, the system could be subject to mechanical vibration and shock, varying environmental temperature, multiple power domains and a large number of interference sources that could deteriorate signals between the centralized management controller and multiple battery integrated circuits. Considering that batteries are the only power source for electric vehicles, instances involving a failure of the system could render an electric vehicle inoperable. With this in mind, Tesla notes that there is a need for a battery management system that is “more robust and dynamic.”

Tesla’s patent describes what could be dubbed as a redundant battery management system, comprising a first client coupled within a multi-channel, bi-directional and daisy-chained communication loop. The electric car maker also outlined a method for identifying a failure location within a battery management system. Tesla describes these as follows.
“The battery management system may include a host (such as a microcontroller that manages at a system level) and clients (such as battery management integrated circuits that manage battery cells within the system). In embodiments, the host may be implemented in various structures including the previously mentioned microcontroller and manages the system by transmitting commands and receiving responses from one or more of the clients. Each client may monitor and control corresponding battery cells to measure the electrical and physical status of the cells, such as voltage, amount of remaining electrical charge and temperature of each cell. For instance, the client 120a may monitor the cells 130a. It is noted that each client may monitor a different number of battery cells. The client 120a may perform measurements (e.g., voltage, charge, temperature, etc.) as well as perform certain functions (e.g., bleed-off charge from a battery cell, etc).”
Tesla further discussed its rationale behind its use of daisy-chain loops for its battery management system.
“The host and each client may communicate commands and responses via a daisy-chain transmission path loop, where the daisy-chain loop may include a pair of wires that transmit electrical signals therethrough. In embodiments, the daisy-chain loop may connect the interface of the host to the interfaces of the clients in series so that communication may serially occur on one or multiple channels within the loop. “
“The battery management system is able to provide redundant communication paths because of its ability to bi-directionally communicate along the daisy-chain loop and because the two channels used on the daisy-chain loop each allow access to completely separate and redundant battery management systems. Specifically, the host is able to communicate in a clockwise direction around the serially connected clients as well as communicate in a counter-clockwise direction along the loop. This bi-directionality allows the host to communicate with each client in case there is a single failure within the daisy-chain loop. This redundancy applies to both channels.”
Ultimately, Tesla notes that these systems will result in what could only be described as “dynamic redundancy” across its battery management systems. This, of course, could foster a new generation of battery packs that are more reliable than the company’s already stellar batteries.
“One skilled in the art will recognize the use of a multi-channel signaling system as well as a bi-directional signaling architecture within the battery management system results in dynamic redundancy across the system itself. For example, if a primary or secondary circuit should fail on a client, the host may communicate a redundant command to the client using a different and fully operational channel. The multiple channel architecture ensures that even egregious malfunction of a sub-system, such as the transmission of spurious data, will not be able to interfere with normal operation of a complementary subsystem operating on a different channel. In addition, the bi-directionality of the system allows for compensation to occur in the event of a complete path failure somewhere within the loop.”
The past months have seen an influx of published patents for Tesla. Among these include an automatic tire inflation system patent that can pave the way for off-road capabilities for the company’s vehicles, a clever patent that would allow Tesla to address panel gaps during vehicle assembly, a patent that describes colored solar roof tiles, and even a system that uses electric cars as a way to improve vehicle positioning.

Chevy answered Tesla’s new Standard Model 3 and Model Y offerings with its second-generation Bolt EV, a car that actually appeals to those who were looking for affordability.
Earlier this week, Tesla unveiled the Model 3 and Model Y Standard, two stripped-down versions of the cars of the same name it already offers. The Long Range versions are now labeled as “Premium,” while the Performance configurations stand alone.
Tesla launches two new affordable models with ‘Standard’ Model 3, Y offerings
However, many people were sort of upset with what Tesla came to market with. For well over a year, it has been transparent that it was planning to develop affordable models, and this year, it was forced to take action to counter the loss of the $7,500 EV tax credit.
The Model 3 Standard starts at $36,990, while the Model Y Standard comes in at $39,990. While these are cheaper than the company’s Premium offerings, many fans said that Tesla missed the mark with the pricing, as these numbers are not necessarily “affordable.”
At the very least, they will likely miss the mark in helping Tesla regain annual growth rates for its deliveries. Tesla will likely rely on its “unboxed process,” which will be used to manufacture the Cybercab and potentially other affordable models in the future. These will be priced at below $30,000.
Other carmakers are making their moves and were able to undercut Tesla’s new Standard offerings, Chevrolet being one of them.
This week, the company launched its second-gen Bolt EV, which starts at just $28,995.
Here are the full specs:
- 65 kWh LFP battery
- 255 miles of range (EPA estimated)
- Native NACS port for Tesla Supercharger accessibility without an adapter
- Up to 150 kW charging speed
- Bidirectional power of 9.6 kW
- Front-Wheel-Drive
- 10-80% charging in just 26 minutes
- No Apple CarPlay or Android Auto
- SuperCruise capable
- 11.3″ touchscreen, 11″ digital gauge cluster
- 16 cubic feet of cargo capacity
- Other Trims
- RS – $32,000
- Base LT – $28,995
- Deliveries begin in early 2026
Let’s be frank: Tesla fans are unlikely to bat an eye at other OEM offerings. However, first-time EV buyers might be looking for something more price accessible, so vehicles under $30,000 are where they will look first, at least for most people.
If money isn’t an option, people will consider spending a minimum of $37,000 on a new vehicle, especially an EV, as a first-time owner.
The Bolt EV could be something that does well, especially considering its one of only a handful of EVs that are priced at around $30,000 brand new in the U.S.
The others are:
- Nissan Leaf S ($28,140)
- Mini Cooper SE ($30,900)
- Fiat 500e ($32,500)
While these cars are priced at around $30,000 and are affordable, they each offer minimal range ratings. The Nissan Leaf S and Fiat 500e have just 149 miles, while the Mini Cooper SE has 114 miles.
Tesla’s flagship sedan, the Model S, has officially been named one of TIME Magazine’s Best Inventions of the 2000s. It joins its sibling, the Model 3, which made the list in 2017.
The Model S is among the most crucial developments in the automotive industry in the last century.
Just as the Ford Model T made its mark on passenger transportation, becoming the first combustion engine vehicle to be successfully developed and marketed at a time when horse and buggy were the preferred mode of transportation, the Model S revolutionized things a step further.
Although it was not the first EV to be developed, the Tesla Model S was the EV that put EVs on the map. In 2012, TIME recognized the Model S as a piece of technology that could truly transform the car industry.
The publication wrote:
“This electric four-door sedan has the lines of a Jaguar, the ability to zip for 265 miles (426 km) on one charge—that’s the equivalent of 89 m.p.g. (2.6 L/100 km)—and touchscreen controls for everything from GPS navigation to adjusting the suspension.”
Looking back, TIME was right on. The Tesla Model S was truly a marvel for its time, and it, along with the OG 2008 Roadster, can be seen as the first two EVs to push electrification to the mainstream.
As TIME described this year, the Model S “proved to be a game-changing experience for electric vehicles,” and it ended up truly catalyzing things for not only the industry, but Tesla as well.
The Model S acted as a fundraiser of sorts for future vehicles, just as the Model X did. They paved the way for the Model 3 and Model Y to be developed and offered by Tesla at a price point that was more acceptable and accessible to the masses.
The Current State of the Tesla Model S
The Model S contributes to a very small percentage of Tesla sales. The company groups the Model S with the Model X and Cybertruck in its quarterly releases.
Last year, that grouping sold 85,133 total units, a small percentage of the 1.789 million cars it delivered to customers in 2024.
Things looked to be changing for the Model S and the Model X this year, as Tesla teased some improvements to the two cars with a refresh. However, it was very underwhelming and only included very minor changes.

It appeared as if Tesla was planning to sunset the two cars, and while it has not taken that stance yet, it seems more likely that the company will begin taking any potential options to heart.
CEO Elon Musk said a few years ago that the two cars were only produced due to “sentimental reasons.”
Tesla (NASDAQ: TSLA) has had a few weeks of overwhelmingly bullish events, and it is inciting several analysts to change their price targets as they expect the stock to potentially go Plaid Mode in the near future.
Over the past week, Tesla has not only posted record deliveries for a single quarter, but it has also rolled out its most robust Full Self-Driving (Supervised) update in a year. The new version is more capable than ever before.

However, these are not the only things moving the company’s overall consensus on Wall Street toward a more bullish tone. There are, in fact, several things that Tesla has in the works that are inciting stronger expectations from analysts in New York.
TD Cowen
TD Cowen increased its price target for Tesla shares from $374 to $509 and gave the stock a ‘Buy’ rating, based on several factors.
Initially, Tesla’s positive deliveries report for Q3 set a bullish tone, which TD Cowen objectively evaluated and recognized as a strong sign. Additionally, the company’s firm stance on ensuring CEO Elon Musk is paid is a positive, as it keeps him with Tesla for more time.

Musk, who achieved each of the tranches on his last pay package, could obtain the elusive title as the world’s first-ever trillionaire, granted he helps Tesla grow considerably over the next decade.
Stifel
Stifel also increased its price target on Tesla from $440 to $483, citing the improvements Tesla made with its Full Self-Driving suite.
The rollout of FSD v14.1 has been a major step forward for the company. Although it’s in its early stages, Musk has said there will be improved versions coming within the next two weeks.
Stifel raises Tesla price target by 9.8% over FSD, Robotaxi advancements
Analysts at the firm also believe the company has a chance to push an Unsupervised version of FSD by the end of the year, but this seems like it’s out of the question currently.
It broke down the company’s FSD suite as worth $213 per share, while Robotaxi and Optimus had a $140 per share and $29 per share analysis, respectively.
Stifel sees Tesla as a major player not only in the self-driving industry but also in AI as a whole, which is something Musk has truly pushed for this year.
UBS
While many firms believe the company is on its way to doing great things and that stock prices will rise from their current level of roughly $430, other firms see it differently.
UBS said it still holds its ‘Sell’ rating on Tesla shares, but it did increase its price target from $215 to $247.
It said this week in a note to investors that it adjusted higher because of the positive deliveries and its potential value with AI and autonomy. However, it also remains cautious on the stock, especially considering the risks in Q4, as nobody truly knows how deliveries will stack up.
In the last month, Tesla shares are up 24 percent.
