Amidst Tesla’s ongoing efforts to usher in an era of mobility optimized for the convenience and security of car owners, the electric automobile maker is researching new methods to better its automobiles ’ systems. Recently published patent applications, for one, indicate that Tesla is operating on greater damage monitoring characteristics , as well as safer seats that are effective at classifying an automobile ’s natives . Apart from these, Tesla is also looking into enhancing its own vehicles’ electric pump machine, which could ultimately lead to better cooling and diagnostics.
The patent software , printed on January 3, 2019 and titled “Electric Pump System and Method,” explores improvements that could be put into place on conventional pump systems used in cars. According to Tesla, conventional oil pumps, especially the ones that are used for EV parts such as the drive device, do not have the ability to track oil condition. As a result, oil that is used to lubricate an electric car’s drive device have to be changed on a regular basis (albeit quite infrequently).
In the discussion part of its patent program, Tesla pointed out that the conventional oil pumps cannot accurately determine temperature, since temperature sensors are usually located out of a conventional pump method. Apart from this, the electric automobile maker notes that conventional oil pumps are also big and unwieldy as a result of attachment mechanisms comprised of different parts. With these points for advancement in mind, Tesla has pointed out that there is a need for the “improved oil pump — in particular an electric pump system — made to work together with an electric engine. ”

Tesla’s patent refers to an electric pump system that “presents structures and methods that help overcome the difficulties of working a lubrication and cooling system, in particular, managing the transport of heat and assessment of fluid temperatures in electric pump systems. ” The Silicon Valley-based carmaker describes its electric pump system layout as follows.
“There is an apparatus that contains an electronic control unit, a mechanical pump, and a motor having a first side and a second side, the engine such as: a stator, a rotor including a hollow rotating shaft, and a home around the stator and rotor, whereas the electronic control unit is connected to the side of the engine, whereas the mechanical pump is connected to the second side of the engine, whereas the hollow rotating shaft defines a rotating shaft inlet and a shaft outlet, whereas the mechanical pump defines a primary fluid passageway from a primary pump inlet into the shaft inlet, whereas the housing defines an internal engine cavity, whereas the shaft outlet is in fluid communication with the internal tube, whereas the mechanical pump defines a second fluid passageway from a second pump inlet into a pump outlet, and wherein the engine housing and mechanical pump specify a third fluid passageway from the internal motor cavity to the pump outlet using a third pump valve. ”
“In certain embodiments the device according to the above-described component of the current disclosure or any other aspects thereof, quite a few optional operations and attributes may be used. One optional feature is the electronic control device further including a thermistor to measure a temperature of a fluid leaving the shaft outlet. Another optional feature is the housing defines a bypass flow in fluid communication with the internal motor cavity. Another optional feature is at the very least a part of the instant fluid passageway along with the next fluid passageway is normal. Another optional feature is that the mechanical pump is really a gerotor. Another optional feature is the electronic control unit comprises a microcontroller controlling the mechanical pump. Another optional feature is the electronic control device includes cooling ribs. ”

With such a layout, the fluid temperatures inside the electric pump system can be used to control and maximize the lubrication system of a vehicle, thus improving the efficacy of an electric drive unit. Based upon the temperatures of the oil in the machine, the electric pump could respond accordingly, even caution the automobile ’s computers that something is wrong. The readings from the electric pump system may be used to track the wellness of an automobile ’s drive device too. Tesla describes this procedure in the following discussion.
“The fluid temperatures may be controlled to attain particular lubrication properties. For example, hotter oil has lower viscosity that reduces drag and hydraulic power to pump up the fluid, which may boost efficacy. If the oil gets too hot, but it will not offer adequate cooling. The fluid temperature studying feature of the oil pump may track the overall health and performance of the fluid at the electric drive unit system. For example, if the oil is too hot, then the oil pump can alert the car computer that something is wrong, for oil that is too hot can harm or/and reduce the life of some components on the drive unit. ”
“Stated another way, the temperatures of fluid may be utilised to track the health and performance of the drive device. The ECU may catch other information besides the temperature, for example pump speed, pump present composition, oil pressure, along with other info. The information captured by the ECU can then be fed into a proprietary formula that tracks oil pump and total drive unit health. The algorithm may provide an indicator of support, such as when oil must be replaced or when the drive train needs to be serviced. ”
What is especially notable is that these improvements can lead to enhancements to Tesla’s drive components, which are among the best in the business. The Model 3’s driveway device, for one, has been lauded by veteran teardown experts such as Sandy Munro as industry-leading. At a recent appearance at Autoline TV, for you personally, Munro noticed that Tesla’s drive components are almost a course above its competitors.
Tesla’s constant attempts to boost its vehicles are highlighted by the patent applications from the business that have been released over the previous months. One of these include a automatic tire inflation system that hints at off-road capacities for the company’so vehicles, even a system that allows Tesla to handle panel interruptions during automobile assembly, a means to produce colored solar roof tiles, and even a version that utilizes electric automobiles as a means to boost vehicle placement, to list a few.
