Re: Is range anxiety real?

1. By what definition does anyone consider "average" adequate?  A car designed to meet my average needs for range will, by definition, strand me on the road exactly 50% of the time.  Not sure about you, but to me that's not acceptable performance.

2. I do know pretty well the range of all of my gasoline cars, and I don't worry about it because (a) none have a range of less than 300 miles; (b) there are gas stations all over the place; and (c) if I do run out of gas, I can carry a 10 pound can of gas back to the car and get it going again.

I do expect electric vehicle technology and infrastructure to improve and become more and more competitive, but I have little patience for engineers who whine about consumers wanting something more than average.

I agree with patb, with the following comments:

Of course range anxiety is real, particularly if you are limited to a single vehicle to cover as many of your particular needs as possible.  Same for towing needs, carrying 9 passengers, off-roading, etc.  Life is choices.

EVs are new technology, with restrictions of capability and available infrastructure.  I'm sure the early drivers of gasoline vehicles has the same anxieties.

The tone of the discussion is that an engineer, unable to provide the ideal solution, tries to convince you that it really is not a limitation.  Better to evaluate the current state of the technology, identify the market that it serves, and make a product appropriate to that market.  The people who find your limitations unacceptable are not part of your market.

I forgot about the gas can! Only once in my life did I run out of gas and that was on my way to a gas station. I missed it by about a half mile. How much does a half mile extension cord weigh?

It's not so much range itself, but first the time required to "refuel" and second the  availability/density of "refueling stations".

Owner or driver?
Battar   8/5/2013 8:56:48 AM
There is a large market for vehicles where the owner is not the driver, and the owner can dictate vehicle usage. For example, light delivery vehicles, which are only used in urban environments and during work hours, or service-call technicians. Fleet owners could operate a mix of gas and electric vehicles according to requirements. For some reason, I don't see EV manufacturers targeting that market.

Right, Rick. I'll add: 

(d) I can refill to full range (300+ miles) in ~5 minutes.

All of the above make the range of a gas / diesel vehicle essentially infinite for most practical purposes.

"Besides, it's the job of engineers to figure out what consumers want and then design to it. It's not the job of engineers to say, "Here's what you should want.""

I follow your logic Nancy. I'm waiting until an EV could even be produced to withstand NW Minnesota. I'd love to see an EV that can go through a foot or so of snow and ice in -30°F weather during a month or two in winter. This is often a daily drive of only about 15-20 miles. However, just like gasoline vehicles, I'm sure conditions tend to play a part in reajusting your drivable range. Now, say a person were to start with a short-range EV with about an 80 mile capacity on the battery. Heaven forbid you get stuck in your driveway on the way to work. I'm thinking the range would be cut to little more than half. If it were a gasoline vehicle, I could still stop and "gas up" on my way home from work, which would take 5 minutes or less. Where or how am I supposed to get "re-charged" on my home commute? Range-anxiety?!?! You bet!! And for darn good reason as far as I'm concerned.

Having been born and raised in Minnesota, many ICE cars cannot function in your described weather conditions. I have had to drive my snowmobile to work a couple of times!

By the way, is there such a thing as an electric snowmobile? I haveseen  electric motorcycles, planes, and even a boat, but have never heard of an electric snowmobile!
