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

Tesla creates clever solution to simplify and improve its Service
Raj Jegannathan, a Vice President of IT/AI-Infra, Apps, Infosec, and Vehicle Service Operations, revealed that Tesla has started a small pilot program at a few service locations to combat this issue.

Tesla has created a clever solution to simplify and improve its Service. Tesla performs most of the services that are needed on its vehicles at its company-owned Service Centers.
However, service has been a weak point of the company, as some regions have fewer Service Centers than others. This can cause long wait times for Tesla owners in some parts of the country.
There are also instances where customers do not agree with what Tesla is saying about their vehicle. In fact, one instance that revealed this new change Tesla is making to its Service was precisely that.
One owner posted on X that his vehicle’s battery seal had failed after a recall was issued. Tesla insurance and Tesla Service both did not assist, and it took CEO Elon Musk stepping in to get the issue resolved:
Will investigate

Another owner suggested there should be a more streamlined communications process between the customer and the Service Center, a solution that has been missing.

Jegannathan said that Tesla has started to share local and regional leader contact information so customers have the ability to reach out when they have complaints or disagree with warranty claims, changes in estimates, or initial diagnostics.
It is available in a handful of locations already, and Jegannathan said that once abuse guardrails are built, this will expand to all locations:

This would be a major improvement in the Service portion of Tesla’s business. There are common disagreements between Service and customers, specifically when Service’s suggestions don’t align with the customer’s beliefs.
When it comes to things like a warranty claim, these issues are not really up for interpretation. Instead, the repairs should be made. If there is a misunderstanding on Service’s side, a simple message from the customer could have resolved the issue. That’s basically what happened here.

Tesla gets its best analysis from Morgan Stanley as ‘it’s all about to change’
He maintained its ‘Overweight’ rating and the $410 price target Morgan Stanley had on the stock.

Tesla has gotten perhaps its best analysis from Morgan Stanley in quite some time, as the Wall Street firm claims that “it’s all about to change.”
That phrase could be used for both the company’s status and the world in general.
Analyst Adam Jonas said in a new note on Thursday to investors that Tesla could be one of the major winners in terms of the global transition from what it is now to what it will be.
He describes the global shift that will occur over the next few years:
“Have you interacted with a robot today? Have you even seen a robot today? No? Well, take a mental picture because it’s all about to change. When we meet someone who has never been in a Waymo or a Tesla Cybercab (which is most people), we frequently see a wince and a response such as ‘I’m not sure I’d feel comfortable getting in a car without a driver.’ We imagine going back in time to 1903 and asking people if they’d feel comfortable in an airplane.’”
The same technological revolutions that have occurred over the past 150 years will continue to occur again and again. We are on the verge of another, Jonas believes, as companies like Tesla are working on artificial intelligence tech, which includes changing the way we look at things like transportation and labor.
Jonas includes an interesting tidbit in his note about how humanoid robots could change wages, and how it could work into the advantage of Tesla, especially as it is developing its own Optimus robot:
“We estimate 1 humanoid robot at $5/hour can do the work of 2 humans at $25/hour, generating an NPV of approximately $200k/humanoid. 1 robot shaped car can potentially drive down cost/mile of a ride share vehicle to <$0.20 mile (1/10th human-driven ride-share).”
Jonas sees Tesla as a key player in how AI will impact things like manufacturing and various automotive industries, and he believes there is long-term potential for AI, robomobility, and even autonomous eVTOL platforms.

Tesla expands Robotaxi program in Austin to new riders
Tesla has been expanding both the rider group and the geofence in Austin slowly, making sure to prioritize safety and avoid any major events with the early rollout.

Tesla is expanding its Robotaxi program in Austin, Texas, as several people have received invitations to participate and take rides.
Tesla first launched the Robotaxi platform on June 22. It invited a handful of people to participate in the first-ever public rides. We were lucky enough to get an invitation, and our permissions have been expanded in the Bay Area pilot program as well.
The group was small and consisted of big names in the Tesla community. It expanded and is continuing to offer these exclusive invitations to notable members of the Tesla community.
There have been fewer than five subsequent invitations after the first group’s were sent in late June:
I’m so stoked!! LFG 🙌🏽🙌🏽 @Tesla @Tesla_AI @robotaxi @elonmusk pic.twitter.com/F4chRhMjc9

Tesla’s new Robotaxi geofence shape is an FU by Elon Musk to the competition
“We are being very cautious. We do not want to take any chances, so we are going to go cautiously. But the service areas and the number of vehicles in operation will increase at a hyper-exponential rate,” CEO Elon Musk said during the Q2 Earnings Call.
Eventually, the Robotaxi platform will not require an invite, and it will operate without geofences. Musk believes Tesla can get there within three or six months, and plans to have at least half of the U.S. population with access to a Robotaxi by the end of the year:

— TESLARATI (@Teslarati) July 23, 2025
“I think we will probably have autonomous ride-hailing in probably half the population of the U.S. by the end of the year. That’s at least our goal, subject to regulatory approvals. I think we will technically be able to do it. Assuming we have regulatory approvals, it’s probably addressing half the population of the U.S. by the end of the year.”
Tesla plans to have regulatory approval in Nevada, Arizona, and Florida sooner than in other states.
