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.

Tesla Sweden finally makes IF Metall union give up 600-day strike
Tesla and the union have opened the door to resolutions that do not involve a collective agreement.

After nearly two years of industrial action and sympathy strikes, Swedish labor union IF Metall has stated that it is softening its stance in its dispute with Tesla. With this, Tesla and the union have opened the door to resolutions that do not involve a collective agreement.
Union chair Marie Nilsson told Sveriges Radio’s Ekot that while the preferred outcome remains a signed agreement, “other alternative solutions” are now on the table.
Union reconsiders rigid demands
The strike, which began over 600 days ago, has been marked by a series of strategic moves from both sides. IF Metall blocked Tesla’s access to license plates by targeting mail delivery, while Tesla bypassed the restrictions by importing vehicles in bulk through German ferries to Trelleborg, among other strategies.
Despite the high-profile tactics, the number of active strikers has been relatively small, just about 60 in total, as noted in a CarUp report. Tesla Sweden has also maintained that it does not intend to bow down to the union’s demands. Over the 600-day strike, Tesla Sweden has adapted its operations to get around the union and its allies’ strikes.
Possible paths to ultimate resolution
Nilsson, for her part, noted that IF Metall is now willing to explore alternatives, such as embedding industry-standard terms directly into Tesla’s employment contracts or shifting Tesla’s Swedish operations to a company that already has a collective agreement.
“You can do it in different ways. The easiest thing would be to sign a collective agreement. But when that is not possible, we have to find other alternative solutions as well, so we are open to discussion,” Nilsson stated.
IF Metall, if any, has acknowledged that Tesla has already improved working conditions in Sweden since the dispute began. Tesla Sweden has argued that its working conditions are already better than union standards, which is reportedly one of the reasons why very few company employees actually participated in IF Metall’s strike.
“There have been conversations throughout the journey where we compared our conditions. Tesla has adjusted details without going into details, they want to be a good employer, it’s about wages and conditions,” Nilsson stated.
Cybertruck
Tesla Cybertruck is getting a big security upgrade
“Cybertruck was not 100% carryover in execution like S3XY, so it required work.”

Tesla confirmed today that a massive Cybertruck security feature is on the way soon, and it is one that owners have been asking about for a long time.
Like all Teslas, Cybertruck has the excellent security feature known as “Sentry Mode.” The feature essentially turns your Tesla into a moving security camera, recording any event that happens nearby.
It has been used to solve crimes such as vandalism and burglary, and even used by police departments to solve other, high-profile crimes.
Tesla quietly added this extra Sentry Mode feature to deter vandals
However, Cybertruck has been missing one key feature of Sentry Mode: the use of the B-Pillar camera has not been enabled, leaving one of the most vandalized and targeted vehicles in the United States with a weakness.
One person who has been vocal about it is Tesla Cybertruck enthusiast Greggertruck, who has been pushing for answers for months. He finally got his answer from Cybertruck Vehicle Program Manager Siddhant Awasthi:
“It will come soon! Cybertruck was not 100% carryover in execution like SX3Y so it required work. Team has finished work on this and just need to make sure it’s validated and runs reliably (which it should for its feature).”

It sounds as if Tesla’s issue was something they similarly experienced when deploying Full Self-Driving to Cybertruck. The other four Tesla vehicles were able to use FSD because they’re all relatively similar in ride height and overall functionality. They share tons of similarities.
Cybertruck did not get FSD right away because Tesla still had to work on the differences between it and the other cars in the lineup. As Awasthi said, “Cybertruck was not 100% carryover in execution like S3XY, so it required work.”
Tesla Cybertruck FSD release expected for Sept, Park Assist to come first
It sounds as if Tesla is close to resolving some of the more intricate details of adding the functionality, and it was just a matter of time before it figured out the issue.
The release of the B-Pillar camera being active during Sentry Mode events on Cybertruck will likely come in a software update in the coming weeks.
Investor's Corner
Tesla investors may be in for a big surprise
All signs point toward a strong quarter for Tesla in terms of deliveries. Investors could be in for a surprise.

Tesla investors have plenty of things to be ecstatic about, considering the company’s confidence in autonomy, AI, robotics, cars, and energy. However, many of them may be in for a big surprise as the end of the $7,500 EV tax credit nears. On September 30, it will be gone for good.
This has put some skepticism in the minds of some investors: the lack of a $7,500 discount for buying a clean energy vehicle may deter many people from affording Tesla’s industry-leading EVs.
Tesla warns consumers of huge, time-sensitive change coming soon
The focus on quarterly deliveries, while potentially waning in terms of importance to the future, is still a big indicator of demand, at least as of now. Of course, there are other factors, most of them economic.
The big push to make the most of the final quarter of the EV tax credit is evident, as Tesla is reminding consumers on social media platforms and through email communications that the $7,500 discount will not be here forever. It will be gone sooner rather than later.
It appears the push to maximize sales this quarter before having to assess how much they will be impacted by the tax credit’s removal is working.
Delivery Wait Time Increases
Wait times for Tesla vehicles are increasing due to what appears to be increased demand for the company’s vehicles. Recently, Model Y delivery wait times were increased from 1-3 weeks to 4-6 weeks.
This puts extra pressure on consumers to pull the trigger on an order, as delivery must be completed by the cutoff date of September 30.
Delivery wait times may have gone up due to an increase in demand as consumers push to make a purchase before losing that $7,500 discount.
More People are Ordering
A post on X by notable Tesla influencer Sawyer Merritt anecdotally shows he has been receiving more DMs than normal from people stating that they’re ordering vehicles before the end of the tax credit:
Anecdotally, I’ve been getting more DMs from people ordering Teslas in the past few days than I have in the last couple of years. As expected, the end of the U.S. EV credit next month is driving a big surge in orders.

It’s not necessarily a confirmation of more orders, but it could be an indication that things are certainly looking that way.
Why Investors Could Be Surprised
Tesla investors could see some positive movement in stock price following the release of the Q3 delivery report, especially if all signs point to increased demand this quarter.
We reported previously that this could end up being a very strong rebounding quarter for Tesla, with so many people taking advantage of the tax credit.
Whether the delivery figures will be higher than normal remains to be seen. But all indications seem to point to Q3 being a very strong quarter for Tesla.
