Tesla is designing an electric pump system that makes its drive units even better

Published

on

Amidst Tesla’s continued efforts to usher in an era of mobility optimized for the convenience and safety of car owners, the electric car maker is exploring new ways to improve its vehicles’ systems. Recently published patent applications, for one, indicate that Tesla is working on better damage monitoring features, as well as safer seats that are capable of classifying a car’s occupants. Apart from these, Tesla is also looking into improving its vehicles’ electric pump system, which could ultimately result in better cooling and diagnostics.

The patent application, published on January 3, 2019 and titled “Electric Pump System and Method,” explores improvements that could be implemented on traditional pump systems used in automobiles. As noted by Tesla, traditional oil pumps, particularly those that are used for EV components such as the drive unit, do not have the capability to monitor oil condition. As a result, oil that is used to lubricate an electric car’s drive unit need to be changed on a regular basis (albeit very infrequently).

In the discussion section of its patent application, Tesla pointed out that traditional oil pumps are unable to accurately determine temperature, since temperature sensors are usually located outside of a conventional pump system. Apart from this, the electric car maker notes that conventional oil pumps are also large and unwieldy due to attachment mechanisms comprised of different parts. With these points for improvement in mind, Tesla has pointed out that there is a need for an “improved oil pump — in particular an electric pump system — designed to work in conjunction with an electric motor.”

Tesla’s patent describes an electric pump system that “presents methods and structures that help overcome the difficulties of operating a cooling and lubrication system, in particular, managing the transfer of heat and assessment of fluid temperature in electric pump systems.” The Silicon Valley-based carmaker describes its electric pump system design as follows.

“There is provided an apparatus that includes an electronic control unit, a mechanical pump, and a motor having a first side and a second side, the motor including: a stator, a rotor including a hollow shaft, and a housing around the stator and rotor, wherein the electronic control unit is connected to the first side of the motor, wherein the mechanical pump is connected to the second side of the motor, wherein the hollow shaft defines a shaft inlet and a shaft outlet, wherein the mechanical pump defines a first fluid passageway from a first pump inlet to the shaft inlet, wherein the housing defines an internal motor cavity, wherein the shaft outlet is in fluid communication with the internal motor cavity, wherein the mechanical pump defines a second fluid passageway from a second pump inlet to a pump outlet, and wherein the motor housing and mechanical pump define a third fluid passageway from the internal motor cavity to the pump outlet via a third pump inlet.”

“In some embodiments the apparatus according to the above-described aspect of the present disclosure or any other aspects thereof, a number of optional operations and features may be employed. One optional feature is the electronic control unit further including a thermistor to measure a temperature of a fluid exiting the shaft outlet. Another optional feature is wherein the housing defines a bypass inlet in fluid communication with the internal motor cavity. Another optional feature is at least a portion of the second fluid passageway and the third fluid passageway is common. Another optional feature is the mechanical pump is a gerotor. Another optional feature is the electronic control unit includes a microcontroller controlling the mechanical pump. Another optional feature is the electronic control unit includes cooling ribs.”

With such a design, the fluid temperature inside the electric pump system could be used to control and optimize the lubrication system of a vehicle, thereby improving the efficiency of an electric drive unit. Depending on the temperature of the oil in the system, the electric pump could react accordingly, even warning the vehicle’s computers that something is wrong. The readings from the electric pump system can be used to monitor the health of a vehicle’s drive unit as well. Tesla explains this process in the following discussion.

“The fluid temperature may be controlled to achieve certain lubrication properties. For example, hotter oil has lower viscosity which reduces drag and hydraulic power to pump the fluid, which can increase efficiency. If the oil becomes too hot, however, it will not provide sufficient cooling. The fluid temperature reading feature of the oil pump can monitor the general health and performance of the fluid in the electric drive unit system. For example, if the oil is too hot, the oil pump may alert the car computer that something is wrong, for oil that is too hot can damage or/and reduce the life of some components on the drive unit.”

“Stated another way, the temperature of fluid may be used to monitor the health and performance of the drive unit. The ECU may capture other information besides the temperature, such as pump speed, pump current composition, oil pressure, or other information. The information captured by the ECU may then be fed into a proprietary algorithm that monitors oil pump and overall drive unit health. The algorithm may provide an indication of service, such as when oil must be replaced or when the drive train needs to be serviced.”

What is particularly notable is that these improvements could result in enhancements to Tesla’s drive units, which are already among the best in the industry. The Model 3’s drive unit, for one, has been lauded by veteran teardown experts such as Sandy Munro as industry-leading. In a recent appearance at Autoline TV, for one, Munro noted that Tesla’s drive units are practically a class above its competitors.

Tesla’s constant efforts to improve its vehicles are highlighted by the patent applications from the company that have been published over the past months. Among these include an automatic tire inflation system that hints at off-road capabilities for the company’s vehicles, a system that allows Tesla to address panel gaps during vehicle assembly, a way to produce colored solar roof tiles, and even a model that utilizes electric cars as a way to improve vehicle positioning, to name a few.

Elon Musk’s warning to legacy automakers: Tesla FSD licensing snub echoes EV dismissal

Published

Elon Musk said in late November that he’s “tried to warn” legacy automakers and “even offered to license Tesla Full Self-Driving, but they don’t want it,” expressing frustration with companies that refuse to adopt the company’s suite, which will eventually be autonomous.

Tesla has long established itself as the leader in self-driving technology, especially in the United States. Although there are formidable competitors, Tesla’s FSD suite is the most robust and is not limited to certain areas or roadways. It operates anywhere and everywhere.

The company’s current position as the leader in self-driving tech is being ignored by legacy automakers, a parallel to what Tesla’s position was with EV development over a decade ago, which was also ignored by competitors.

The reluctance mirrors how legacy automakers initially dismissed EVs, only to scramble in catch-up mode years later–a pattern that highlights their historical underestimation of disruptive innovations from Tesla.

Elon Musk’s Self-Driving Licensing Attempts

Musk and Tesla have tried to push Full Self-Driving to other car companies, with no true suitors, despite ongoing conversations for years. Tesla’s FSD is aiming to become more robust through comprehensive data collection and a larger fleet, something the company has tried to establish through a subscription program, free trials, and other strategies.

Tesla CEO Elon Musk sends rivals dire warning about Full Self-Driving

However, competing companies have not wanted to license FSD for a handful of speculative reasons: competitive pride, regulatory concerns, high costs, or preference for in-house development.

Déjà vu All Over Again

Tesla tried to portray the importance of EVs long ago, as in the 2010s, executives from companies like Ford and GM downplayed the importance of sustainable powertrains as niche or unprofitable.

Musk once said in a 2014 interview that rivals woke up to electric powertrains when the Model S started to disrupt things and gained some market share. Things got really serious upon the launch of the Model 3 in 2017, as a mass-market vehicle was what Tesla was missing from its lineup.

This caused legacy companies to truly wake up; they were losing market share to Tesla’s new and exciting tech that offered less maintenance, a fresh take on passenger auto, and other advantages. They were late to the party, and although they have all launched vehicles of their own, they still lag in two major areas: sales and infrastructure, leaning on Tesla for the latter.

Musk’s past warnings have been plentiful. In 2017, he responded to critics who stated Tesla was chasing subsidies. He responded, “Few people know that we started Tesla when GM forcibly recalled all electric cars from customers in 2003 and then crushed them in a junkyard,” adding that “they would be doing nothing” on EVs without Tesla’s efforts.

Companies laughed off Tesla’s prowess with EVs, only to realize they had made a grave mistake later on.

It looks to be happening once again.

A Pattern of Underestimation

Both EVs and self-driving tech represent major paradigm shifts that legacy players view as threats to their established business models; it’s hard to change. However, these early push-aways from new tech only result in reactive strategies later on, usually resulting in what pains they are facing now.

Ford is scaling back its EV efforts, and GM’s projects are hurting. Although they both have in-house self-driving projects, they are falling well behind the progress of Tesla and even other competitors.

It is getting to a point where short-term risk will become a long-term setback, and they may have to rely on a company to pull them out of a tough situation later on, just as it did with Tesla and EV charging infrastructure.

Tesla has continued to innovate, while legacy automakers have lagged behind, and it has cost them dearly.

Implications and Future Outlook

Moving forward, Tesla’s progress will continue to accelerate, while a dismissive attitude by other companies will continue to penalize them, especially as time goes on. Falling further behind in self-driving could eventually lead to market share erosion, as autonomy could be a crucial part of vehicle marketing within the next few years.

Eventually, companies could be forced into joint partnerships as economic pressures mount. Some companies did this with EVs, but it has not resulted in very much.

Self-driving efforts are not only a strength for companies themselves, but they also contribute to other things, like affordability and safety.

Tesla has exhibited data that specifically shows its self-driving tech is safer than human drivers, most recently by a considerable margin. This would help with eliminating accidents and making roads safer.

Additionally, competition in the market is a good thing, as it drives costs down and helps innovation continue on an upward trend.

Conclusion

The parallels are unmistakable: a decade ago, legacy automakers laughed off electric vehicles as toys for tree-huggers, crushed their own EV programs, and bet everything on the internal-combustion status quo–only to watch Tesla redefine the industry while they scrambled for billions in catch-up capital.

Today, the same companies are turning down repeated offers to license Tesla’s Full Self-Driving technology, insisting they can build better autonomy in-house, even as their own programs stumble through recalls, layoffs, and missed milestones. History is not merely rhyming; it is repeating almost note-for-note.

Elon Musk has spent twenty years warning that the auto industry’s bureaucratic inertia and short-term thinking will leave it stranded on the wrong side of technological revolutions. The question is no longer whether Tesla is ahead–it is whether the giants of Detroit, Stuttgart, and Toyota will finally listen before the next wave leaves them watching another leader pull away in the rear-view mirror.

This time, the stakes are not just market share; they are the very definition of what a car will be in the decades ahead.

A video posted on social media has shown an occupied Waymo driverless taxi driving directly into the middle of an active LAPD standoff in downtown Los Angeles. 

As could be seen in the short video, which was initially posted on Instagram by user Alex Choi, a Waymo driverless taxi drove directly into the middle of an active LAPD standoff in downtown Los Angeles. 

The driverless taxi made an unprotected left turn despite what appeared to be a red light, briefly entering a police perimeter. At the time, officers seemed to be giving commands to a prone suspect on the ground, who looked quite surprised at the sudden presence of the driverless vehicle. 

People on the sidewalk, including the person who was filming the video, could be heard chuckling at the Waymo’s strange behavior. 

The Waymo reportedly cleared the area within seconds. No injuries occurred, and the passengers inside the vehicle were safely transported to their destination, as per a Waymo representative. Still, the video spread across social media, with numerous netizens poking fun at the gaffe.

Others also pointed out that such a gaffe would have resulted in widespread controversy had the vehicle involved been a Tesla on FSD. Tesla is constantly under scrutiny, with TSLA shorts and similar groups actively trying to put down the company’s FSD program.

A Tesla on FSD or Robotaxi accidentally driving into an active police standoff would likely cause lawsuits, nonstop media coverage, and calls for a worldwide ban, at the least.

This was one of the reasons why even minor traffic infractions committed by the company’s Robotaxis during their initial rollout in Austin received nationwide media attention. This particular Waymo incident, however, will likely not receive as much coverage.

Tesla Model Y demand in China is through the roof, and new delivery dates show the company has already sold out its allocation of the all-electric crossover for 2025.

The Model Y has been the most popular vehicle in the world in both of the last two years, outpacing incredibly popular vehicles like the Toyota RAV 4. In China, the EV market is substantially more saturated, with more competitors than in any other market.

However, Tesla has been kind to the Chinese market, as it has launched trim levels for the Model Y in the country that are not available anywhere else. Demand has been strong for the Model Y in China; it ranks in the top 5 of all EVs in the country, trailing the BYD Seagull, Wuling Hongguang Mini EV, and the Geely Galaxy Xingyuan.

The other three models ahead of the Model Y are priced substantially lower.

Tesla is still dealing with strong demand for the Model Y, and the company is now pushing delivery dates to early 2026, meaning the vehicle is sold out for the year:

Tesla experienced a 9.9 percent year-over-year rise in its China-made EV sales for November, meaning there is some serious potential for the automaker moving into next year despite increased competition.

There have been a lot of questions surrounding how Tesla would perform globally with more competition, but it seems to have a good grasp of various markets because of its vehicles, its charging infrastructure, and its Full Self-Driving (FSD) suite, which has been expanding to more countries as of late.

Tesla Model Y is still China’s best-selling premium EV through October

Tesla holds a dominating lead in the United States with EV registrations, and performs incredibly well in several European countries.

With demand in China looking strong, it will be interesting to see how the company ends the year in terms of global deliveries.
