Re: Batteries that Last

Most of the warranties that I hear about are like the Volt's, which is eight years/100,000 miles on its 16-kWh battery. That's less important for a conventional hybrid, which will typically have a 1-kWh or 2-kWh battery that may use a less costly nickel-metal hydride chemistry.

If it can be done, it certainly makes sense, davtrowbridge. Right now, the cells make up only about half of the pack costs, according to most of the estimates that I hear. If you can cut the cost of the cooling system, that pack cost could drop significantly.

New chemistries

I note that getting 15 to 20 years is contingent on power and cooling management systems, which adds to the cost of the battery subsystem. New chemistries may reduce or eliminate the need for these systems; the cost reduction this will make possible is needed to penetrate the burgeoning stop-start market.

Full disclosure: I'm affiliated with Leyden Energy, which is developing such a chemistry.

Batteries that Last

Chuck, With possible replacement costs potentially that high, it makes sense that buyers would be concerned to get some kind of long term service agreement to protects against catastrophe. Do you have any idea if this is common? I have heard with some hybrids that these agreements are available.

It's especially good news, Rob, when you consider the price of replacement batteries. A year ago, when a Tesla customer fried his Roadster battery, Tesla gave him a "friends and family" price of $40,000 for a new one. Most batteries are smaller than the Roadster's, but a few are even larger, so cost is a big consideration.

The batteries need to last

This is good news, Chuck. Many of us keep cars well beyond eight years. Stats show that the way to get the most out of a car economically is to run it till it falls apart. That can mean 15 to 20 years. If EVs and hybrids can't make it that long, it's a mark against them. So a long-life battery is good news.

Just how far has handheld gaming technology come? Let's take a look inside the Nintendo 3DS XL and find out.
Design, simulation, manufacturability, and prototyping: All of these phases are being pushed forward and progressively by underlying technologies.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
