GM Thinks Tetris-Shaped Batteries Could Be the Key to Better Cooling Battery cells are typically only rectangular or cylindrical. GM might change that. General Motors?has plans to operate four battery plants, with one in?Lordstown, Ohio?already pumping out cells. With the ability to make its own batteries comes the potential for custom configurations and form factors, something the company is considering taking to the extreme. A recent patent from GM shows batteries not shaped like rectangles or cylinders, but Tetris-like blocks meant to accommodate more efficient cooling channels. #ThermalComfortinBuildings #AutomotiveCabinComfort #DataCenterCooling #ThermalManagementinelectronics #BiomechanicsandBiomedicalApplications #Aeroacoustics #EnvironmentalandClimateModeling #UrbanAirflowandPollutionControl #Gasturbineselectrification #Electrificationforagriculturalequipments #IndustrialMixingandChemicalProcessing #Fannoisecontrol

Different Types of Batteries Used in Automotive

Future Car Battery Cell Production - BMW No.2（Causes and Solutions） I'll provide my take on the previous video and would be grateful for your feedback. (Phenomenon) ?(1:30, 1:50) Wrinkles in the foil between the 3 stripe coating. 　This may cause various problems in the TAB forming and laser 　　　 　welding processes in the later processes. (Countermeasures) 1) Product design that keeps the calender pressure low. 　 The degree of foil wrinkling is determined by the calender pressure, which makes the thickest coating part as thin as possible. 2) The thickness of the coating part of each stripe is equal and uniform. Control by radiation alone does not capture thickness changes, causing wrinkles in the foil after the calender. A hybrid type of density meter (radiation, etc.) + thickness meter is desirable (Maysun developed product). (Phenomenon) ?(7:23) Uneven edges or product width error If it is simply a lack of adjustment of the EPC (edge position controller), optimization is possible, but the occurrence of product width errors is a major problem. (Countermeasures) ?Uneven edges EPC changed to high performance type, especially type that allows selection of material centering method according to operating specifications such as speed. ?Product width error 　 Product width error caused by poor cutting is eliminated by 　　 　 optimizing cutting conditions that determine cutting quality. Slitting with the material firmly held by the shaft-type lower 　　　 　 knife is preferable, and by using a single upper knife with built-in contact pressure sensor between the upper and lower knives as in the Maysun type, cutting conditions before operation and cutting conditions during operation can be digitally monitored to confirm optimal conditions. (Maysun standard product) 　We welcome your opinions and objections, so we look forward to 　　 　hearing from you！??

GM has published patents detailing a novel hydraulic air gap control system for axial flux motors. This tech could allow for smaller, lighter, and more efficient motors by dynamically adjusting torque and speed characteristics on the fly. The potential benefits are huge - increased range, lower costs, and zippy performance, all from a more compact package. Exactly what affordable, mass-market EVs need. While still early stage, GM's axial flux innovations underscore the engineering processes going into realizing the EV dream. An exciting development that could help EVs go mainstream.

How many batteries could you CT scan in ONE YEAR with ONE Lumafield Triton? ?? ?? ?? ?? ?? ?? ?? ?? 31,536,000 seconds in a year ÷ 10 seconds per battery cell CT scan = 3,153,600 full battery cells inspected for internal defects (impressive math, I know) **This assumes 24 hour shifts running 356 days/year. Almost never the case.** Regardless, how does this compare to battery manufacturing volumes across the largest producers in the world? Not as simple of an equation... Mass battery production is often measured in watt-hours (Wh), referring to the electrical capacity of all the cells combined. Depending on size (and quality) they offer different electrical capacities. However, I found the Tesla Cybertruck to provide a good example. This vehicle uses 1,344 cells (big 4680s manufactured in-house). If they wanted to ensure quality on every single cell installed in the packs inside the Cybertruck, how many vehicles would they be able to produce annually? 2,346. (8.6% of total Cybertrucks sold currently) With one battery line. With one scanner. With complete peace-of-mind on cell quality.

I recently dived into the Tesla Cybertruck manual and came across some fascinating insights about its drivetrain. The Cybertruck employs a dual motor system: Front Motor: AC Induction Motor with a Variable Frequency Drive (VFD) Rear Motor: AC Permanent Magnet Synchronous Motor (PMSM) with a VFD An AC induction motor produces a rotating magnetic field which induces a current in the rotor. The induced current in the rotor produces its own magnetic field that follows the stator's magnetic field. PMSM's operate with permanent magnets in the rotor to produce a constant magnetic field. VFD's adjust the motor's speed and torque to match the vehicle's demands. Ultimately, this dual motor system enables the Cypertruck to be a complete behemoth on the road. #ElectricalEngineering #Tesla #Cybertruck #AutomotiveEngineering #MotorTechnology #VariableFrequencyDrive #ACInductionMotor #PermanentMagnetMotor #ElectricVehicles ##GreenTech

Talking about MOSFET Characterization Test, engineers depend on accurate characterization of devices for understanding and, in more complex scenarios, modeling device behavior of seven FET tests cover I-V and C-V characterization : Drain current vs drain voltage, Drain current vs gate voltage, Threshold voltage, Subthreshold voltage, Gate leakage, On-state resistance, Gate capacitance In the automotive industry, MOSFETs are key components that support the efficiency, performance, and reliability of various electronic systems in modern vehicles, making them indispensable for advancements in automotive technology. Here are several reasons why MOSFETs are essential in the automotive sector : - Power Efficiency : MOSFETs are used in power management systems to reduce power losses and increase energy efficiency, which is particularly important for electric and hybrid vehicles. - Motor Control : In applications such as electric motor drives for electric vehicles, MOSFETs help control the speed and torque of the motor efficiently. - Battery Management : MOSFETs are utilized in battery management systems to regulate the charging and discharging of batteries, ensuring long lifespan and optimal performance of vehicle batteries. - Safety Systems : MOSFETs are used in various active and passive safety systems, such as airbags, ABS (Anti-lock Braking System), and vehicle stability control.
