Nissan Unveils All-Electric LEAF 586
MojoRilla writes "In Japan, Nissan unveiled their all-electric LEAF (press release, and Flash site). Slated to launch in late 2010 in Japan, the US, and Europe, this car will have a 100-mile range, seats 5, has an advanced computer system with remote control by IPhone, and promises to be competitively priced. While this car's range won't work for everyone, it could be a game changer as a commuter car." Recharge time is 8 hours with a 200-volt power source, and "just under 30 minutes with a quick charger" (no further details given) to charge to 80% of capacity.

I'm starting a company to do just that -- Celadon Applications, LLC. We already have a fully functional prototype and are in the middle of raising money to add some more features and polish to make it into a commercial product (the prototype is a bit cluttered and could use to be more user-friendly). The prototype [rechargeamerica.net] makes use of weather forecasts, 10-meter altitude data with a vertical resolution of 4 inches, and so forth, along with driver behavior modeling and physics calculations every several meters to determine how much charge you'll have at each point along the trip. The final version will have a very powerful crowd-sourced, trust network-validated charger database overlay on the map as well (it's coded, but is currently being debugged). So you find your route won't make it to your destination, no problem -- you drag it over to a charging station. And you can click on the station, get pictures, reviews, find what there is to do in the area, etc. It'll initially be populated with not just "known" recharging stations, but also "likely" recharging places, such as RV parks and so forth -- as well as phone numbers and email addresses to contact their owners. And you can add your own charging stations, even just a high-power outlet in your garage -- and list a fee for it if you want.
We've done some accuracy validation on the simulator part with a Tesla Roadster. Of 7-ish legs that we tested, all but one of them were in the 2-4% error range. The last one was on surface streets and was about 12% error because Google was way off on how much traffic there was going to be (they said 40 minutes, it actually took closer to 25); when we hard-coded it to get the amount of traffic right, it fell back into the normal error range. To counter that issue, we're going to add real-time traffic forecasts in wherever available. Oh, and this is so far without any of Tesla's help. If we can get more detailed hardware specs, we can do even better.
The market forecasts range wildly, but they range from a million or two EVs up to 32.7 million shipped by 2015 (Wintergreen Research). Either way, it's a massive market, and even with just a couple percent penetration, there's huge profit potential and the potential to create a lot of jobs. And it should help open up the EV market to a lot of people who wouldn't otherwise consider them. And most of our competition is way behind -- the standard approach, you'll find, is just to draw a circle around the car and say this is how far you can drive (as though you can go just as far over the top of Mount Whitney as you can over flat land on good roads).

As an result-oriented environmentalist, this disappoints me immensely.
In short, Amdahl's law says that when you want to improve a system that is made up of lots of different components, you do best to improve the lowest-performing part first. In programming, that means focusing your performance analysis on the parts of the program that are taking the most time before you focus on making the fast parts faster. In terms of automobiles, that means you should replace the most fuel-guzzling part of the fleet before you start thinking about making the thrifty cars thriftier.
Let's do some numbers, for the same number of miles driven, replacing a 12 mpg vehicle with a 15 mpg vehicle saves you as much as replacing a 30 MPG vehicle with a 60 MPG vehicle. Improve that 12 mpg to 18 mpg and now you need to replace a 30 mpg with a 180 MPG car (the EPA calculates the carbon-cost of an electric vehicle using our mix of power source to be roughly 120 mpg) to match the fuel savings.
So if we were really serious about making a dent in oil consumption and CO2, we would be pushing for more fuel-efficient pickup trucks, cargo vans and SUVs instead of this inane (but highly press-friendly!) pursuit of ever-more-efficient small vehicles. The people that drive those vehicles can't or won't replace them with small cars no matter how efficient.
Ultimately, it comes down to whether we value results or whether we value cool technology. As a gadget-nerd, I freely admit that all-electric cars are much sexier than a new pickup truck that gets 16 mpg instead of 12. But the programmer inside me knows that the pickup truck will probably do a lot more good over the lifetime of the vehicle. There are only so many R&D dollars going around and I feel like they aren't being well spent (from the point of view of the environment -- for marketing, the halo effect of the Prius is definitely worth it).

Apartments were one of the first spots with internet access, because you could run a few lines and connect up a few hundred people.
Likewise, some company will be offering a cut of metered electric service to the apartment complexes, and they'll be able to list "EV Charging Spots" as an amenity to the apartment.
Really, once an electric car is mass produced, inexpensive, and safe, the rest of the problems that come up are completely trivial.

200 volt power source (Score:2)
Recharge time is dependent on amp-hours, not volts. If you hook up a 200 volt power source that can only deliver 1 amp, you are not going to charge your batteries in 8 hours because that is only 8 amp-hours.
I image that the car is designed around residential wiring, which is usually 12 gauge and rated at 20 amps, so in 8 hours you should get 8*20=160 amp-hours, which at the quoted 200 volts is 32kWatt-hours. Based on $0.10 per kWh, it should cost $3.

Lithium-ion batteries are not ready for this task. They are not easy to make. That is why they cost a fortune. I don't think I am alone, but I have never had a Li-ion laptop battery make it more than 1 year in a laptop. After about 1 year the run time on the battery goes from 2 hours ( new ) down to 30-45 minutes. Plus, I don't run on battery power that often. Less than 2 hours a week. This tech is not ready to be put in mass produced cars. I know all the new claims about longevity. I bet the those who believe those claims also believe the claims Lenovo made about the battery in my current laptop. Battery life claims are notoriously unreliable.
One issue is that Li-ion batteries are very sensitive to heat. Leave them out in the sun, and their capacity will drop like a rock - even if you do not use them. This is going to be a huge problem anywhere where it is sunny through much of the year. Heat kills a Li-ion battery's longevity. Parking a car under the LA sun is a perfect way to quickly kill an electric car.
I don't know how much the Nissan battery pack will cost, but a Tesla battery pack runs about $30,000. If you replace it every 2 years, the cost quickly gets out of hand. My guess is that Nissan will not make an binding promises about warranting the battery pack. If it fails ( drops to less than 50% initial capacity ) in less than 3 years, you will be SOL.
I did see an article in the WSJ ( Wall Street Journal ) about an electric lawn mover about 2 months ago. The company clearly stated that the $800 battery pack would have to be replaced approximately every 2 years. Sadly, I think this is the brutal reality when it comes to battery powered vehicles. Massive piles of batteries that will require disposal, and the expense of purchasing new while disposing on the old.
I think a better solution is a supercharged engine that is 1.5 liters or less. Add to that capacitors and electric motors for acceleration. Capacitors are light, so they don't weigh down a car like batteries do. When and only when accelerating, the capacitors power the electric motors to give acceptable acceleration. When cruising, a 1.5 liter supercharge engine should be able to carry most light cars along at 100 mph or less no problem. Massive power is only needed for high speeds ( 100+ mph ) and rapid acceleration. When cruising at constant speed, it does not matter if you have 600 hp or 90 hp. During cruising and braking, the capacitors can be recharged. The capacitors only need enough power for short bursts. They discharge quickly, but also recharge quickly. Start and stop traffic might wear down the power in the capacitors fast than the system can recharge. However, you can accelerate on the engine alone in start and stop traffic. You generally don't need rapid acceleration in start and stop traffic.
Keep in mind coal power production is not exactly what one would call efficient ( less than 50% ). Nor is power transmission ( 10% or more loss ). Nor is turning electricity back into forward momentum. Also, high efficiency batteries are going to require a lot of rare earth metals. Unfortunately, world supply is limited.

100-mile range is misleading (Score:3, Interesting)
Nissan is knowingly setting itself up to over-promise and under-deliver by quoting the EPA range of 100 miles, because the EPA test is well known to be extremely optimistic for EVs. AC Propulsion's eBox has an EPA range of ~170 miles, but a realistic range of 130. Tesla's Roadster has an EPA range of ~220 miles, but a realistic range of 175.
Nissan's car will probably have a realistic range of 70-80 miles. The good news is that this is more than enough for many, many households. The bad news is that many households don't realize it, because "range anxiety" is a very real (psychological) phenomenon, even though actual range limits are not.

Hopefully the chargers aren't locked out while moving. Not only does the GEN not have to meet as many emissions standards ( = cheaper) but has other uses also.

A DOT vehicle can easily carry the batteries to get you to a charging station or even back to your house.
The hurricane fear mongering is just sad.
And maintenance is far less expensive for an EV, because it's far less complicated mechanically. If you'd done any research on the GM vehicle, you'd know that they basically rotated the tires. There are Priuses with over a hundred thousand miles that haven't needed new batteries. And the batteries will be less expensive too replace than putting in an entirely new engine, so you could literally keep the same car for decades if you kept it rust free.
Honestly, who is paying you to repeat the same inane bullshit?

So, given the choice between saving thousands dollars a year on gasoline and maintenance, or renting a car for the entire week you get for vacation and the few weekends you can get out of town, you'll pick the more expensive option?
You said this car was "doomed" because it doesn't work for anyone, which is complete nonsense. For many people I know, who nearly always travel to their vacation via airplane, and who rarely leave town on the weekends, a cheap electric plus an occasional rental is the most economic option. And most people live in cities, not out in the sticks.
If you regularly leave on the weekends and you can only afford one car, then go with an ICE. If you live in the sticks, get an ICE. Otherwise, if you do the math, this is the way to go.
