motor efficiency | Tesla Motors Club
2015年3月18日 · The efficiency (mechanical power output by motor divided by electric power input to inverter) varies from 0 when the motor outputs 0 kW of power to about 85% when the motor outputs 30 kW of power. At about 10 mph, the mechanical power output by the motor is about 1 kW and efficiency is 30%.
Electric Motor Efficiency vs. Increased Speeds - Tesla Motors Club
2015年6月10日 · There is something that I have yet to understand, regarding range efficiency vs. speed. I have always thought (from my limited understanding of electric motor efficiency), that there is a direct, linear, correlation between speed and energy consumption (the higher the speed, the higher the consumption per unit of time, in a linear fashion).
Can anybody provide model S motor efficiency diagram??? - Tesla …
2015年10月3日 · The Prius motor efficiency is the highest per that graph around 2200 RPM, which I would describe as nearer the middle than the lower or top end. It is also more effecient on the top side of the torque area as the RPM rises and has a large blob in the high torque low rpm area. Tesla's motors are larger all the way around.
Motor or Efficiency Loss over time | Tesla Motors Club
2011年8月19日 · One way to differentiate between a motor issue like you're thinking and a drag/load issue like I'm suggesting would be a coast down type test - take the car up to some fairly high safe speed on a straight quiet piece of road (100 kph?) and then shift it to neutral and record how the speed drops (could take notes or use a stop watch, but a phone ...
efficiency | Tesla Motors Club
2024年5月8日 · Having driven the MX 75D (20inch wheel) for over 4 years, I have checked its average efficiency after 41K miles of driving. Based on the last 28K miles, EPA is 350wh/mile. But on the highway driving 70~75mph, I think the efficiency drops to 400wh/mile. For a long distance trip I need to charge...
Does electric motor performance degrade? | Tesla Motors Club
2020年4月28日 · The net result is that yes, the motor does degrade, but none of these will measurably affect the peak power output, temperature/cooling, torque, or efficiency. At some point, something will degrade to the point of failure (likely the bearings will be first), requiring a motor replacement, but with many fewer things to go wrong, this extends the ...
Does Chill mode increase efficiency? Surprisingly, Tesla says yes
2023年9月2日 · Chill mode improves efficiency even if you don't have a heat pump. And that's because the simple fact of energy to work relation. The faster work being done the more energy is consumed. This is one of the basic laws of physics. Chill mode makes the pedal less sensitive. And that increases the time voltage is delivered to the motor.
Five Year Review -- Tesla Model 3 Dual Motor AWD
2023年11月20日 · My Model 3 Dual Motor AWD net cost after tax rebates and incentives was about $47,500 -- cheaper than the price of a comparable BMW 328 or Audi A4. Cost and incentives were certainly a factor, but Model 3 also had the best technology as it was the first car in decades that was different – it came with an embryonic Full Self Driving package ...
Tires: MXM4 vs other options for model 3 tires - Tesla Motors Club
2020年1月28日 · Maybe some other efficiency-focused tires are just as efficient now, but I think you're unlikely to end up with significantly better efficiency than the MXM4. MXM4 performance and road feel is atrocious even compared to many non-sporting all seasons, but if you're fine with those aspects, they certainly have their benefits which seem to match ...
2023 Model Y LR Poor Mileage in real world | Tesla Motors Club
2023年1月10日 · My lifetime efficiency is 265 Wh/mi; this winter the efficiency has been ~300Wh/mi to 320 Wh/mi; My 2020 LRMY is using ~20% more energy in winter. This is for local driving, short distances. I do precondition before driving for 5 to 10 minutes. (I almost never plug in at home because I am able to use free public Level 2 charging.
