So we now know you lose battery time in both heat and cold. I will stick with my gas car

The Biden Administration, as we have seen in recent reporting, seems determined to get Americans to switch to an electric vehicle (EV) whether you like it or not. This is done in the name of “green” policies and climate change, but it’s been known for some time that cold weather dramatically reduces the range an EV has per charge. But now, we learn that hot weather can have the same effect.A new study suggests that excessive heat can greatly diminish electric vehicle range. The findings are similar to other studies that show how excessive cold also reduces range. Thankfully, it seems as though the range is mostly unaffected unless the temperature is in the triple digits.

Seattle-based Recurrent studies and tests thousands of vehicles each year in order to analyze the relationship between batteries and their range. Its latest data indicates that when things get really hot, EVs could lose almost a third of their stated range. While Recurrent didn’t name names, it says that some vehicles saw a drop in their range of 31 percent when temperatures climbed above 100 degrees Fahrenheit (38 degrees Celsius).
It’s significant to note that, this summer, much of the American Southwest has seen temps consistently over 100 degrees. If you live in Phoenix or Tucson, Arizona, Las Vegas, Nevada, or Las Cruces, New Mexico, prepare to lose 30 percent of your EV’s range through most of the summer.

Recurrent, the company that has done this testing, has already shown how freezing cold weather affects EV performance:

Recurrent is the same company that last year found that freezing temperatures have a nearly identical effect. Both the Ford Mustang Mach-E and the Volkswagen ID.4 saw dips in range of 30 percent when temps dropped below 30 degrees Fahrenheit (-1 degrees Celsius). At the same time, it’s worth noting that less extreme temperatures exhibit very little influence on battery range.

In Phoenix the loss is closer to 40%. 30% is at 100 to 110 degrees. Phoenix has been over 110 for the entire month of July so far...

Then your range drops more because in Western cities you tend to do more highway driving at high speeds with no braking or slowing. Testing has shown this will reduce milage compared to EPA testing by another 10 to 15%.

You are in the desert
 
I have never seen the range drop on hot days. It does on cold days though. Gas mileage o ICEs is lower in winter too.
 
We need to know names...Tesla says that their superior battery tech does not have this problem big like some of the others.

ICEs have the same weather problems. In cold weather, they lose 15 percent of range. https://www.utilimarc.com/blog/winter-range-ice-vs-ev/ EVs also do not have to overcome the heat caused by the engine, so their air conditioning is much less of a drain.

Nope. ICE cars perform BETTER at cold temperature. Denser air. Their air conditioners have the condensor located in front of the engine AND in front of the main radiator, not in back. They do not have to overcome the heat of the engine at all. Further, on cold days, the HEATER is being used rather than the air conditioner. That's free heat from the engine.

EVs DO have to overcome the heat caused by the 'engine'. Both the batteries and the motors are liquid cooled. Further, the compressor consumes battery power to run. The heater requires battery to run also. At cold temperatures, battery chemistry runs slower, reducing overall range by quite a lot.

Tinker has stated that they live in AZ and can you tell you, for fact, that this is all BS and it is no hotter now than it was decades ago.

The data says otherwise and i cited it but Tinker stands by their view as accurate because it is based on their personal feelings in this area and the need to deny anything and everything 'climate change'.

Not to mention in cold weather, the battery 'cooling' system becomes heated drawing power from the battery to keep the temperature elevated rather than reduced. The whole idea of that system is to keep the battery at a constant, optimal, temperature.

There is no data.
Climate cannot change. Climate has no temperature.

Not quite. While there is a battery heater in EVs, it does NOT heat the battery to 'optimal temperatures'. It only heats the battery enough to keep the coolant or the battery itselffrom freezing. This of course requires power from the battery, reducing it's range. As the car is driven, it's own waste heat is sufficient to keep it from freezing and the heater is shut off to save power. The battery is STILL operating at reduced temperatures, reducing it's range.

I’ll play your stupid game, fine, depends upon how one defines data, climate, change, and temperature

Three men walk into a hotel looking for a hotel late one night looking for a room …………………..

It is no game. It is English (which you ignore), mathematics (which you ignore) and science (which you ignore).

Climate is a subjective description. It has no values associated with it. It cannot change. There is no value that can change. Climate has no temperature.
The concept of temperature is defined by the 0th law of thermodynamics, which you discard and ignore.

Data is a measurement of a value (such as temperature). A statistical summary is not data.
To create a statistical summary, you must:
* Provide data that is published. That data MUST be collected without bias.
* Provide the time the data was collected.
* Provide and justify the method that data was collected and how that collection method prevents bias.
* If instrumentation is used, provide the tolerance information for that instrumentation and when it was last calibrated and by who and it's method of calibration.
* Declare and justify your range of variance. You must show why the range is relevant.
* Select from your data using randN.
* Normalize your selection using paired randR.
* Calculate the mean of the selected data.
* Calculate the margin of error value.
* Publish BOTH the margin of error value and the mean.

Statistical mathematics is NOT capable of prediction due to it's importation of random numbers. Note that two summaries on the SAME data can result in a DIFFERENT summary.

You have no data.
You do not know what 'climate' means.
Climate cannot change.
You do not know what 'temperature' means.

YOU ARE MAKING SHIT UP.

Tesla and GM both use an electric heating system to warm the battery to within it's expected operating range. In looking that up, I discovered that Tesla has a sensor that will automatically turn on the car's air conditioning if the cabin temperature exceeds 105 degrees. That means, leave your Tesla out in the sun in Phoenix, it will run the AC nearly continuously to keep the cabin of the car cool.
