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 snags Lamborghini alum to help in newly entered market
Tesla has snagged a Lamborghini alum to help with its entrance into a new market, which has proven to be an intricate situation for the automaker.
A report from Bloomberg states that Tesla has hired Sharad Agarwal, who was formerly employed by the Italian luxury carmaker, to run its operations in India. With Lamborghini, he was employed to handle operations in India.
Tesla launches in India with Model Y, showing pricing will be biggest challenge
Tesla has gone through quite a few different team members with its launch in India, starting with a few hirings a few years ago, well before the company actually committed to selling cars in the country.
The move helps Tesla streamline its executive decision-making process, as it previously had employees in India reach out to managers based in China, among other areas. Agarwal will be stationed in India and will handle the company’s operations.
Tesla’s mentality behind the strategy is to have local leadership, something that seems to cater to the market specifically.
Tesla had previously put Isabel Fan, the manager of Southeast Asia for the company, in the position. However, Tesla seemed to want someone who was more permanent and would be dedicated to India exclusively.
India has the largest population on Earth and has a massive automotive market for that reason. Tesla stands to gain a lot from a strong performance in India, and its clean energy vehicles could help with pollution of all kinds in the region.
Tesla’s path to entrance in the Indian market was a long one, as the company tried for nearly ten years to get into the elusive region. Back in 2016, CEO Elon Musk said Tesla “would love to be in India,” teasing the Model 3.
By 2017, Tesla had met with officials from the country, but tried to get import duties down to nothing from 100 percent.
Indian authorities denied Tesla’s request.
For years, Musk met with Prime Minister Narendra Modi to try and iron out a deal of some sort. Nothing truly came to fruition, at least until last year, when real movement started.
By 2024, India had introduced a strategy to reduce import duties for some companies, which was enough for Tesla to make a move. It is now 2025, and the company still has not committed to building a factory in the region. However, it is not completely out of the question.

Tesla Sentry Mode helps lock up drive-by shooting suspect in Seattle
“A nearby Tesla actually captured the video that showed a man crouched behind a vehicle firing gunshots. A lot of vehicles record, and officers know that Teslas, especially, record, so we use that video all the time in these instances.”
Police in Seattle, Washington, are crediting Tesla’s well-known Sentry Mode for helping find a suspect in a drive-by shooting case.
A 21-year-old was arrested for an alleged drive-by shooting in the Pioneer Square neighborhood of Seattle this past Sunday, and the leads on the case seemed to be slim.
However, a Tesla parked nearby was able to record the shooting, as well as the car that the suspect hopped in after the crime occurred. It helped police identify the person they were looking for.
Seattle Police Department Detective Brian Pritchard said to MyNorthwest that the Tesla was a critical part of finding the suspect and placing him under arrest:
“A nearby Tesla actually captured the video that showed a man crouched behind a vehicle firing gunshots. A lot of vehicles record, and officers know that Teslas, especially, record, so we use that video all the time in these instances.”
The Tesla footage helped the Police put the suspect into handcuffs about an hour after the crime was committed. They are currently charged with drive-by shooting and unlawful possession of a firearm.
Tesla Sentry Mode is a security feature the vehicle utilizes to help solve crimes like vandalism, but it is also a cool feature that has caught things like accidents and other incidents on camera.
Many people still do not know about it, including the many vandals who keyed or broke the windows of Teslas earlier this year, as people damaged others’ cars in an act of retaliation against CEO Elon Musk when he became involved in politics.
This is far from the first time Sentry Mode has helped Police Departments solve crimes. Last September, we reported on Oakland’s Police Department in California using Teslas near crime scenes to help solve cases.
Tesla Sentry Mode is Oakland PD’s secret weapon against rising crime
Sergeant Ben Therriault, president of the Richmond Police Officers Association, said, “We have all these mobile video devices floating around,” in reference to the Teslas that sit and capture nearly everything that surrounds them.
Sentry Mode has helped officers arrest a variety of suspects, including several people who were allegedly involved in the murder of a 27-year-old woman in Northern California.

UPDATE: Tesla investors push Charles Schwab for Musk comp plan clarification
Update: 4:00 p.m. EDT – Charles Schwab has reached out to TESLARATI with the following statement, clarifying that it plans to vote FOR Musk’s compensation package:
“Schwab Asset Management’s approach to voting on proxy matters is thorough and deliberate. We utilize a structured process that focuses on protecting and promoting shareholder value. We apply our own internal guidelines and do not rely on recommendations from Glass Lewis or ISS. In accordance with this process, Schwab Asset Management intends to vote in favor of the 2025 CEO performance award proposal. We firmly believe that supporting this proposal aligns both management and shareholder interests, ensuring the best outcome for all parties involved.”
There have also been updates to the headline and various paragraphs to reflect this as well as accuracy.
Tesla investors are pushing Charles Schwab for clarification after it was expected to vote against CEO Elon Musk’s pay package.
Several high-profile Tesla influencers are speaking out against Charles Schwab, saying its decision to vote against the plan that would retain Musk as CEO and give him potentially more voting power if he can achieve the tranches set by the company’s Board of Directors.
The Tesla community appeared to see that Schwab is one firm that tends to vote against Musk’s compensation plans, as they also voted against the CEO’s 2018 pay package, which was passed by shareholders but then denied by a Delaware Chancery Court.
Schwab’s move was recognized by investors within the Tesla community and now they are speaking out about it:
Hey @CharlesSchwab – I need to speak with someone from Schwab Private Wealth Services this week. Please reach out via email, the mobile app message center, phone, or X DM.
Here’s why this is urgent: At least 6 of your ETF funds (around 7 million $TSLA shares) voted against… https://t.co/uSgPWnfTFc
— Jason DeBolt ⚡️ (@jasondebolt) November 3, 2025
If @CharlesSchwab doesn’t vote for Elon Musk’s 2025 CEO Performance Award plan, I’ll move all my assets to another brokerage. My followers, many of whom also hold assets with Schwab and collectively own at least hundreds of millions in $TSLA, may do the same.
I can’t in good… https://t.co/6iUU6PdzYx

— Gali (@Gfilche) November 3, 2025
At least six of Charles Schwab’s ETFs were expected to vote against Tesla’s Board recommendation to support the compensation plan for Musk. The six ETFs represent around 7 million Tesla $TSLA shares.
Jason DeBolt, an all-in Tesla shareholder, summarized the firm’s decision really well:
“As a custodian of ETF shares, your fiduciary duty is to vote in shareholders’ best interests. For a board that has delivered extraordinary returns, voting against their recommendations doesn’t align with retail investors, Tesla employees, or the leadership we invested to support. If Schwab’s proxy voting policies don’t reflect shareholder interests, my followers and I will move our collective tens of millions in $TSLA shares (or possibly hundreds of millions) to a broker that does, via account transfer as soon as this week.”
Tesla shareholders will vote on Musk’s pay package on Thursday at the Annual Shareholders Meeting in Austin, Texas.
It seems more likely than not that it will pass, but investors have made it clear they want a decisive victory, as it could clear the path for any issues with shareholder lawsuits in the future, as it did with Musk’s past pay package.
