I’m not sure what speed they’re driving at to get 150 miles of range… It’s a simple fact that most EV owners should know that efficiency is inversely squared proportional to speed. I could get 300 miles on a full charge after 1 year/37,000 miles in my Model 3, in 50F weather by just going slower (55mph) and running the seat heaters instead of the heat. The battery degradation is the largest after the first year too, so this is great.
Although I do just keep the display to percentage now. I still use the 1% = 3 miles calculation, even though it’s slowly getting worse than that.
Sure, but the article indicates that tesla was deliberately inflating predicted range in their in-car displays. In other words, they were/are engaged in fraud.
I didn’t see it say that at all. I did see it say that they take every legal advantage they can to claim the absolute highest range possible; no matter how unrealistic that may be. Most other manufacturers don’t do that, instead choosing to claim a more realistic range.
The EPA really need to rethink this range calculation crap. I don’t understand why the manufacturers get so much freedom to choose the vehicle’s range.
Tesla years ago began exaggerating its vehicles’ potential driving distance – by rigging their range-estimating software. The company decided about a decade ago, for marketing purposes, to write algorithms for its range meter that would show drivers “rosy” projections for the distance it could travel on a full battery, according to a person familiar with an early design of the software for its in-dash readouts.
Then, when the battery fell below 50% of its maximum charge, the algorithm would show drivers more realistic projections for their remaining driving range, this person said. To prevent drivers from getting stranded as their predicted range started declining more quickly, Teslas were designed with a “safety buffer,” allowing about 15 miles (24 km) of additional range even after the dash readout showed an empty battery, the source said.
Oh duh, the car display thing. I was just thinking of the EPA rated range for some reason, which doesn’t really seem possible for them to defraud with.
I forget that the car even displays that range on the display since I changed mine to percentage the day I got it.
And Tesla can obviously predict range well, since they do such a good job with the navigation predicted arrival range. That has always been spot on for, like predicting my arrival percentage with in a percent or two even when I’m like 2 hours away.
The EPA doesn’t test the EPA range, the manufacturer does. So it’s entirely possible to cheat, and it’s likely you’ve heard of some famous cases of cheating. Maybe a case involving VW and emissions?
Tesla’s EPA estimate is the most out of line with real world tests whenever any independent organization tries to recreate the claimed range, and that shouldn’t be a surprise to anyone given Teslas long history of bending the truth. They also have the most egregious “correction factor” for their range test that I’ve seen any manufacturer adopt.
I have a Mid Range Model 3, so it works out to 1% = 2 miles for me. But on this last road trip, I had the range estimate give me some wild predictions like 25% of the battery to go 100 miles. If I had followed the car’s directions, there were two times I would have run out of charge miles from a charger.
After reading the details of the “range projection algorithm” it 100% explains the weird projections I was receiving.
