Why range anxiety is not a real problem

The phrase “range anxiety” typically refers to the worry that a battery electric vehicle – a Nissan LEAF, BMW i3, Chevrolet Spark, you name it – will run out of charge and leave you stranded by the side of the road.

It exists because no currently produced EV other than the Tesla Model S (which is capable of up to 295 miles of cruising range) can offer more than 93 miles of range per charge, which certainly poses some limitations on the utility of these cars.

However...

A strong case can be made that anyone in the market for this type of electric vehicle will almost never actually experience the dreaded malaise of range anxiety, as the Rocky Mountain Institute recently pointed out. Here is why.

Even assuming that the average American drives 15,000 miles per year (the actual figure is closer to 13,000) this only equates to about 40 miles per day. And surely that yearly total normally includes a few lengthy road trips, which are not what today’s EVs are designed for, with the obvious exception of Model S.

So the actual daily figure in typical driving for the average American is even lower than 40 miles. Sure, some have long commutes for which, say, a Nissan LEAF (with an EPA-rated 84-mile range) would be impractical, but the vast majority will find that 80-odd miles is more than enough range for a day or two of driving.

In fact, according to data from the EV Project, on days the car is used LEAF drivers travel an average of about 30 miles per day with a mean trip distance of 7 miles.

The increasing availability of workplace charging is also effectively increasing the commute distance an electric vehicle is capable of, doubling it in most cases. The EV project found that Nissan LEAF drivers with access to workplace charging did 65% of their charging at home and 32% at work, while LEAF drivers without workplace charging filled up 84% of the time at home. Those who are provided with charging stations at their workplace clearly take advantage of it.

What does this tell us?

Despite all the hand-wringing over range anxiety, the data clearly shows us that for drivers that actually own electric vehicles, range anxiety for all intents and purposes does not exist. For the rare foray far from home, EV drivers can take advantage of the growing public charging infrastructure.

That’s not to say the owner of a Nissan LEAF will never have to carefully plan a trip to avoid running out of battery – especially in winter, reduced driving range can pose a legitimate problem to the most careful of drivers.

But the larger point is that this type of electric vehicle is aimed at a certain niche, and a fairly huge one at that. The number of multi-car households in the United States is enormous, and most of these households have at least one vehicle that serves mainly as the around-town or commuter vehicle.

It is this application that electric cars like the Nissan LEAF are designed for – not to replace the family hauler or take on vacation, but to provide an incredibly efficient, clean, and satisfying way to get to and from work and around town. And for that purpose, electric vehicles are unmatched by any car with an internal combustion engine. Just ask their owners, who demonstrate staggering rates of owner satisfaction across the board.

To put it bluntly, if you buy a LEAF to drive it from San Francisco to Los Angeles, you’re clearly doing it wrong. Not that it isn’t possible – with California’s robust charging infrastructure, it actually wouldn’t be all that difficult – but it is not the car’s intended purpose, and people usually buy cars with their intended use in mind.

Anecdotal evidence, the finest form

Bear with me as I provide the most convincing form of evidence (as long as the storyteller is in the room): an anecdote.

I was influential in my parents’ decision to lease a Nissan LEAF in January, and they have not regretted the decision. With two kids still at home, my parents both work 10-15 miles away and have a fair amount of chauffeuring and errands to do on the side. Since my father teaches at a university on the top of a frequently snowy mountain, my mother gets the LEAF as her daily driver, and she loves it.

My family has experienced range anxiety exactly twice in the last 10 months. Once, a miscommunication led to the car not being plugged in prior to my brother attempting a trip up the aforementioned mountain. With a half-full battery and not realizing the difference between the range estimator and battery state-of-charge estimator, he panicked as the range meter plunged on his way up and turned around to head for home rather than risk being stranded.

The other occasion was a case of poor planning. My father and brother attempted an ambitious 100-mile trip, with the intention of charging at a Nissan dealer for a few hours at their destination. The charging session was cut short when the dealer closed, however, and the trip home got very interesting. Hypermiling on the highway allowed them to make it to a local mall where they plugged in for a 20-minute trickle charge (the public charging infrastructure buildout has yet to spread to central Pennsylvania) before impatiently setting off for home, only to have the battery die at the bottom of the driveway. I think it is safe to say that anxiety was one of the emotions they experienced on that particular trip, but it was definitely avoidable.

To sum up, range anxiety is only fretted over by those that do not actually own electric vehicles. Those that take the plunge and purchase an EV to meet their needs, however, quickly discover that range anxiety is largely but a figment of the imagination.
