Nissan Leaf Drive Train is 25 Times More Reliable than Conventional Cars

[Updated 5/4/2015 to delete potentially incorrect information about storage space and battery size.]


My Leaf parked in front of a seventies vintage Ford Pinto (my first car was a Pinto). Car technology has come a long way.

Nissan recently released the results of a five year study that found 99.99 percent of its battery packs are still operating as warrantied (battery not having less than 80 percent capacity after five years). Using that information, a study conducted by Warranty Direct (an independent British insurance specialist) found that the Leaf drive train is 0.255/0.01 =25 times more reliable than internal combustion engines. This is, however, somewhat misleading because today’s conventional cars are amazingly reliable, especially compared to a 1973 Pinto. They found that out of 50,000 conventional cars aged 3-6 years old, only a quarter of one percent “had an issue that led to an immobilization of the internal combustion engine.” This finding appears to have led Glass’s (Britain’s used car guide) to conclude:

“They [Leafs] are good enough that, as an expert in this field, we will be looking again at our residual value forecasts for LEAF and probably revising them upwards. Long-term battery life has been a definite concern for used EV buyers but the new figures from Nissan effectively remove this worry.

“Really, Nissan has gone through a process with the LEAF similar to Toyota with the first generation Prius several years ago, where the cars had to be proven in real life conditions before used buyers could feel confident. Now, the Prius enjoys excellent residuals and the LEAF should start to find a similar level of market acceptance.”

Some Thoughts on the Second Tesla Model S Fire

Like the Hummer once was, the Tesla is a status symbol (but for a different crowd). Considering its outrageous price tag, one would be hard-pressed to argue that it is a practical car for the masses. But that’s OK with me, because the Tesla is an ambassador for all electric cars through a process called “status by association” (which is what name dropping is all about). We are social primates… like it or not, status seeking is built into our genes.

On the flip side, it could harm the image of electric cars if this latest trend of catching on fire continues, or accelerates. I’ve looked into the statistics and have concluded that, to date, a significantly smaller percentage of Tesla’s catch on fire than conventional cars. Although, that could change with time. Two spectacular fires in almost as many weeks is not a good thing. A lithium fire with exploding batteries is something to behold and makes good copy. It’s also dangerous if the driver should be incapacitated. To date, no Nissan Leaf has caught fire. 35,000 Leafs have been sold in the U.S. compared to 15,000 Tesla Model S sedans. But that might change as well.

Testing the Electric Car Battery Warranty Waters

Before the Chevy Volt (a plug-in hybrid) went on sale, Volt Chief Engineer Andrew Farah openly acknowledged that the extreme temperatures found in the Southwest have the potential to permanently reduce the battery pack’s capacity to store energy:

“The Volt may not be right for everyone. If you live in the Southwest, depending on how you use your car, the Volt might not be right for you.”

So what is a manufacturer to do if a given customer’s driving habits consistently exposes his or her battery pack to excessively high temperatures in a place like Tucson, or charges it five times a day, or maybe applies a blowtorch to it? As it turns out, the answer depends on what the warranty says, not so much on what the owner’s manual warns you not to do.

Electric Vehicle Charging and the Range Anxiety Myth

Bosch has just entered the EV charging market with its simple 240 volt Power Max charging station for $499.00. Considering that dishwashers, clothes dryers, and hot water heaters can cost less than that, you can bet that the price for this small, relatively simple device will eventually be a lot lower. The Ecotality Blink charging station in my garage cost about $1,200. Neither is actually a charger. They are devices that interface with the charger carried inside the car. How fast you can charge with 240 volts is ultimately limited by the charger that came with the car. The difference is that the Blink station interfaces with the internet, allowing the DOE to study my charging habits, which is fine by me because they paid for it.

The Ecotality Business Model

Ecotality is also installing Level 2 (240 volt) charging stations in business parking lots. For now, charging is free but eventually you will be charged for your, ah, charge. I don’t see this business model having a long-term future. An analogy might be a company that designed a hitching post tailored for Henry Ford’s first car design (that looked a lot like a buggy) which might have seemed like a great idea by car and saloon owners until they realized you don’t need a hitching post for a car.

High Cost Prevents Electric Cars From Penetrating the Market

We see this week news that Tesla is having trouble meeting it’s loan repayment schedule, and faces a need to raise more money on the markets. Combined with this week’s pronouncement from the chief of Toyota against electric cars and lackluster sales of GM’s Volt that have forced the company to reduce production, it seems there are more troubles ahead for electric-driven cars.

I believe this shows that pure electric cars are not yet ready for the consumer market. They are both too expensive, and they don’t meet the needs of consumers for range and performance.

Tesla and Fisker, in particular face consumer challenges that the traditional car makers do not face. As a start-up, they have to convince customers that they can both make a reliable car, and their small dealer network will be able to maintain the cars when they need servicing and repair. (See more: CBO: Electric Cars Will Flop, Despite $7.5 Billion in Subsidies)

The US government provides a tax credit of up to $7500 for purchasers of electric or plug-in hybrid cars. But, for cars that range in price from about $35,000 for the Leaf, to $45,000 for the Volt, to $57,000 for the baseline Tesla Model S, that does not drive the price down to a place where it would be competitive with high efficiency traditional gasoline-driven cars, or even hybrids, which are probably the source of the most competition.

The problem, in short, is that the battery-only cars (Leaf, Tesla, Fisker) are inferior cars at a higher price point.

First Vehicle to Home Power System in North America

Nissan issued a press release earlier this month to announce that Power Stream will be using the V2H system with its fleet of Leafs in Canada. This device acts as a charger and as a power inverter, allowing 4 hour charges instead of 8 hours as well as the capacity to power a home for a couple of days in the event of a power outage. Apparently your Leaf has to have the CHAdeMO protocol quick charge port which was an option on the 2012 cars. The price seems about right to me costing roughly twice as much as the charge stations now installed in homes but that’s still cheaper than a charge station and a backup generator system. And if… Continue»

Chevy Volt Sales Pick Up in March

Last week, in my post about the new Better Place electric vehicle company, I wrote that I was concerned that the electric vehicle “economic model cannot work in places like the U.S. where prices are lower, spaces are bigger, and there is not as much [government] support.”

I really do think that there’s not yet a good reason to buy an electric vehicle here in the U.S. yet. Though gas prices are approaching a nationwide average of $4.00 (it was $3.94 this week), I still don’t think that’s high enough to justify the extra cost. For instance, a Chevrolet Volt costs $40,000 (plus a $7,500 tax credit), while the Cruze, which is basically the same car with a 138 hp gasoline powered engine, costs only $17,000. Even at $4 per gallon, it’s hard to make those numbers match up. Across the Atlantic, though, where gas prices are higher and there are higher sales taxes on traditional cars, it can make more sense.

Electric Car Technology Upgrades, Subsidies, and the Anti-Nuke Crowd

Updated Charging Technology

An email recently came in from Blink telling me they want to install a new card in my electric car charger. New technology always involves a learning curve. If any discipline should be a science (other than science), it is engineering but even engineering involves a lot of trial and error. The first jet engines were unbelievably primitive by today’s standards.

The new Leaf will have a more efficient heating system that will extend the range in cold weather. Not sure what they are up to but hopefully it is one of these heat pumps. It will also come with a charger that is about twice as fast as the one on my car. Oh well. Obsolete already.

Do Government Subsidies Ever Pay Off?

The answer largely depends on your definition of a subsidy and what you mean by payoff.

I’d suggest that many, if not most, subsidies are a roll of the dice (crap shoot) when it comes to the purported pay off. They are social experiments without any guarantee of success, which is not to say they should not be undertaken as long as a mechanism is in place to end the subsidy in a timely manner.

There are many examples that have paid off royally, along with many that were (and are) a waste of time and money to varying degrees.
