Futures of EVs: Buy The Range You Want

CleanTechnica.com: We are still in the early stages of EV development. One of the bigger issues slowing widespread acceptance is the fact that electric car driving ranges are still, for the most part, quite low. As Zach has pointed out, and I agree, the range issue is a canard since the current ranges are adequate for 90%+ of drivers.

The shorter ranges are, however, not adequate for occasional weekend or other longer trips, which is a common auto use. Many of us might not be willing to give up that use when buying a vehicle, so there exists real market pressure for longer ranges. This article is about addressing the needs of the entire driving public for full EV market acceptance. It explores the future direction of EV driving ranges and choices that may become available. Your comments on the topic, as always, are welcome below the article.


High-Range EV Batteries Coming “Quite Soon”

First, we need a reliable high-range battery system. This is in the works. As is the case with most technologies, they keep improving over time. There is no reason to believe that EV batteries will be any different. Indeed, we have already seen significant improvements over the recent years.

It has been stated by Elon Musk that high-range battery systems are coming “… quite soon.” Tesla may have an 800 km (500 mi) range car within a handful of years. This would have an impact on the auto’s price of course. Let’s take a look at a mature technology to see if there may be any clues about the future of EV battery technology.

Mature Technology Case History: Computer Purchases

While it’s funny to think that Bill Gates might have said in 1981 that he saw no need for anyone to ever need more than 640k of memory, he does deny this less-than-prescient comment. Computing history of course belies that statement, whether he said it or not. Memory capacity keeps increasing, but is there currently too much memory capacity potential for most computing needs?

The evidence bears this out as true. If you were to go online to order a computer, the computer company would give choices such as how much memory you want to buy. You see that you can pay for 8 GB RAM, 16, 32 or 64 GB RAM. Of course, buying more RAM would cost you more money. What happens? Almost all consumers don’t buy the highest amounts of memory because they simply don’t need it. They prefer to save the money instead of over-buying capacity.
What Will EV Car Buyers Do?

While this is speculation, EVs are likely going in this very direction. Once there is a battery system that goes 800 km (500 mi) and car buyers only need a 325 km (202 mi) range, would most drivers want to pay for more range than they need? It’s not likely. Most car buyers would probably prefer to buy the battery/range combination that match their driving needs and wallet potential. Car buyers have proven over the decades that they do like having the choice of paying for upgrades or saving money for standard features.
Speculation for the Future of EVs

This article is being written to suggest that this principle will apply to EVs as battery technology matures. For example, there may be a 325 km (202 mi) battery pack for price $X, a 500 km (310 mi) battery pack for $X + $Y and an 805 km (500 mi) battery pack for $X + $Y + $Z.
Solid Baseline Range Being Established

In the same interview mentioned earlier, Elon Musk seems to bear out the first part of this article’s thesis, which is that he seems to be proudly putting forward a car with a 322 km (200 mi) range as an adequate baseline range. He states: “We’re going to keep improving battery technology and even with Model 3 we’ll expect a range of over 200 miles with a price of around $35,000.”



To test out this theory, I contacted a few EV manufacturers to get their opinions and add their comments into the story. First, more context:

Why Might There be Longer Driving Ranges Needed in the US?

US = 9,147,420 sq. km with large cities spread all over it.
China = 9,327,490 sq. km, but most big cities are only in the eastern portion.
Australia = 7,682,300 sq. km with most of the large cities in the east, southeast, and south.
India = 3,287,263 sq. km with large cities all over it.
Germany = 348,570 sq. km, is about half the size of Texas alone, which has 695,621 sq km.
United Kingdom is not quite the size of Nevada (241,930 sq. km vs. 286,351 sq km).
South Korea is about the size of Kentucky (100,032 Sq. km vs. 104,659 sq km).
Japan is 86% the size of California (364,500 Sq. km vs. 423,970 sq. km).

What Are the EV Manufacturers Saying on the Topic?

Tesla
Tesla isn’t saying any more than to what Elon Musk said about a 800 km (500 mi) range electric car that could be coming “quite soon.” My interpretation is that it is sticking to its game plan and keeping the focus on the possible. It often keeps the dialog in the realm of what’s possible, the imagination, and what will soon be. It is, in my opinion, masters at this.

General Motors
Kevin Kelly, Manager of Electrification Technology Communications at GM, agrees with this prospect of the future of EVs. In a phone interview, Kevin stated, “I think what you are talking about is a feasible idea. We could definitely see this happening. The key is making the battery fill within the same footprint. I don’t think this is anything you will see in the near future, but in the long term, it’s a distinct possibility.”

Ford
Ford was guarded on the subject. Ford Manager of Sustainability Communications John Cangany stated: “Your question touches on business decisions car manufacturers make with EVs, so I can’t provide detail on this topic.”

Nissan
Corporate Communications Senior Manager Brian Brockman stated: “On the concept of Nissan offering several battery sizes for EVs in the future to match consumer needs, it is a model we are studying. I can’t confirm that we will or will not offer that as an option, as I can’t comment on our future product strategy.”

This comment not only validates the theory of multiple battery packs being offered for consumers to select their range, but it states that a leading EV manufacturer is studying this model currently.

Side note about Tesla’s Media Services staff:

Tesla’s Media Services staff responded to my email request for a comment in 11 minutes. They replied with what I consider to be a thorough comment including a link to an article already published with an interview of Elon Musk that included comments on battery range. Pretty impressive. (Now, if only Tesla’s Marketing Department would accept my suggestion of naming an EV model “The Valdez,” with the simple marketing campaign of only 3 words: “Remember the Valdez.”)

Battery Technology Development

Battery breakthroughs are announced with some regularity, including Sakti3’s recent announcement. As Elon Musk has pointed out, these don’t usually amount to much in the way of reliable systems. Real battery improvements have been made over the last decade, though, and battery technology will continue to improve because there’s a lot of money in it.
Conclusion: The Future of Buying EV Range

When battery technology arrives as a fully mature technology, the likelihood exists that there will be a baseline expectation range, which will probably be in the 325 km (202 mi) to 500 km (310 mi) range with “options packages” that car makers are famous for offering, which will allow for higher driving ranges for a premium price.
