Data from thousands of EVs shows the average daily driving distance is a small percentage of the EPA range of most EVs.
For years, range anxiety has been a major barrier to wider EV adoption in the U.S. It’s a common fear: imagine being in the middle of nowhere, with 5% juice remaining in your battery, and nowhere to charge. A nightmare nobody ever wants to experience, right? But a new study proves that in the real world, that’s a highly improbable scenario.
After analyzing information from 18,000 EVs across all 50 U.S. states, battery health and data start-up Recurrent found something we sort of knew but took for granted. The average distance Americans cover daily constitutes only a small percentage of what EVs are capable of covering thanks to modern-day battery and powertrain systems.
The study revealed that depending on the state, the average daily driving distance for EVs was between 20 and 45 miles, consuming only 8 to 16% of a battery’s EPA-rated range. Most EVs on sale today in the U.S. offer around 250 miles of range, and many models are capable of covering over 300 miles.
All the complexity of a gas engine
Batteries are more complex. A 200lb battery is less complex than 1000lb or 2000lb battery.
EDIT: I’m an electrical engineer. I can prove to you the complexities of a modern EV Battery. Or do you think 400V systems composed of parallel transistors, battery-management systems, and a whole slew of literally fucking computers estimating the internal-state of the thousands of individual cells that compose a modern EV is a “simple” task?
EDIT: Do you know what kind of degrees you need to design a battery-management system? To mass produce those circuit boards? And to do it all over again 2 years from now when all the chemistries change and therefore the internal estimates of each of these cells completely and drastically changes? No? Please stop pretending that “Batteries” are simple.
Case in point: it’s the battery that will most likely fail in ALL of the discussed designs here. Why? Because chemistry is incredibly difficult and hasn’t been solved yet. I do await for the future improvements in the EV battery pack that are sure to come over the next few years and decade… But let’s not pretend that anything is done R&D yet.
The gasoline engine? Okay we’re up to Atkinson cycle so that’s a bit different but was around in the 1800s anyway. Nothing is really new or complex here. The engines mechanics were understood nearly two centuries ago.
There’s a reason why gasoline engines are so reliable, while batteries keep having faults. Complexity has a lot to do with it.
What happens when you don’t use the gas engine for months and then go to start it with gelled gas?
If only computers existed and had timers that automatically burned off stale gasoline.
Also, just fill up 2 gallons or so to minimize the stale gasoline effect. You’ll only be filling up once or twice a month with all the EV driving you’ll be doing in practice.
You’re trying to solve a problem that the article shows doesn’t exist for 99%
No. The 800+ to 1500+ extra lbs of battery you lug around with a full 300mi electric car is what’s actually being wasted in practice.
Batteries are absolutely not more complex than an internal combustion car. They’re newer, but not more complex.
Why is it that all the batteries are the things that fail in these designs?
And why is it that the gasoline engine lasts for a decade or longer, with very few repair issues? In fact, when was the last time you heard of an old car where the engine needed to be replaced?
When old cars break down, its the suspensions, the belts… radiator (those things rust / break surprisingly often), etc. etc. Its not really the ICE parts that break down.
Check engine lights, oil leaks, coolant leaks transmission leaks, timing belts, timing chains, thermostats, water pumps, compression leaks, vacuum leaks, catalytic converters, oxygen sensors, ignition coils , spark plugs, spark plug wires, distributors, fuel pumps, fuel filters, fuel leaks, cracked block, thrown rod, warped crankshaft, scorn cam shaft, cam phasers, differentials, transmission problems and on… and on…
These are just SOME of the repairs that are common to ONLY gas vehicles and you won’t have any of these problems with an EV.
Sorry, fellow me/ee, disagree on complexity, having worked directly with both. Advantage of mechanical systems: theoretically predictable action, repeated endlessly so long as torque at the tires is req’d. Reality: tolerances in various parts open over time, resulting in a nonlinear decrease in efficiency and power. A symphony of hundreds of bolted joints, springs, tappets and valves, a sum of thousands of parts dancing while a complex ECU watches over the system. A single part or joint far enough out of tolerance will cause very, very expensive damage.
Battery powered vehicles: motor has full torque at close to zero RPM, all components in the control system are solid state, and software (always updateable) handles control decisions. Electric motor has 6 to 30 parts, based on whether liquid cooled or air cooled.
I mean just that.
The internal chemical structure of Li-ion is only designed to work for a limited number of charge/discharge cycles. As the chemistry is stressed out, the internal metals begin to form dendrites (or in more simple terms, spikes) internally.
We have reasonable estimates for how long this takes, but everyone’s battery pack is different. And the process is invisible (you have to cut open & destroy a battery to figure out how much of these dendrites or whatever have formed). So the best we got are some computers slapped on the outside of the battery pack that measures temperature, voltage, current, and time to guestimate the effects from the outside.
As cells fail, modern BMS systems will reroute power away from degenerated cells. Its not that the problem was solved per se, its that modern battery packs have a bunch of extra cells waiting in reserve to pretend that nothing has happened to the end user. But this process eventually breaks enough cells that the whole pack fails and inevitably needs replacement.
Exactly when depends on how many cells were left in reserve, how much “fast charging” you do (which is extremely harsh on the internal chemicals), the temperature of the pack under use, and any aggressive driving you might do that heats up the pack more than usual.
Its… really complex. There’s a lot of research going on right now to try to stop these dendrites from forming.
EDIT: In any case, Consumer Reports reliability surveys on various parts of say… a Toyota Prius Prime or other PHEVs. Go look at them all, see what parts fail. Its the battery.
Here’s GM Volt. What’s the problem? Oh, the EV Battery again, and looks like the EV Charger is also terrible cause GM must have messed that up too.
But yes, its the electrical parts that are more complex and prone to failure in almost all of these cars.
Here’s Chrysler Pacifica. Oh boy, lots of parts of this vehicle is terrible. But as predicted, the EV Battery is among the worst of parts again.
You chose GM and Chrysler as your reliability targets…………
A 40mi PHEV battery is getting a lot more wear put on it from going 0-100% than a 300mi battery that’ll bounce between 50-80%
If I have a 400 V 50 kWh battery and charge at 400 V 50 kW, won’t it be charging at 1 C? Like you could use the Nissan leaf as an example but it’s dishonest since it’s the worst type of battery cooling, air, which makes the cells die prematurely.
Tesla is one of the more failure prone brands. Hybrids are a bad solution since it won’t address the problem fully, and only serves to lengthen the ICE industry.
It’s interesting to be on the other side of watching a subject matter expert being downvoted by laymen suffering from Dunning Kruger. Their feelings will always Trump your knowledge.
I’ve read enough on these systems to understand you’re speaking the truth here. Thanks for trying. I learned some new details on these system’s complexities.
