lithium ion battery pack Toyota's Problem With Plug-in Hybrids

NEW YORK CITY--
The "thought conference" is the international urban planning conference (60 th Floor, JP Morgan office building) held in the most urban environment for a tutorial on the inherent problems of plug-ins, this is probably a less likely setting.
In hybrid (PHEV) cars, Toyota is the main sponsor, and it has certain advantages.
Irv Miller, vice president of environmental and public affairs at Toyota group, answered the PHEV question;
Bill reinat, national manager of the company's advanced technology.
Although Toyota will launch its own 500 Prius fleet
Based on the marketing experiment of PHEVs, their main point is that the cost of PHEVS is too high and the environmental benefits are too low.
Instead of some proponents claiming 100 miles per gallon, plug
They said it was actually between 50 and 55 miles. -
There is no better company than the third generation Prius. it is no coincidence that it is only launched.
The promise of lithium, Miller said.
Ion battery pack--
For electric vehicles and electric vehicles with pure batteries-
Led to "excessive expectations beyond the technical reality ".
As evidence of irrational prosperity, he mentioned that San Francisco mayor Newson has declared that the traditional hybrid "yesterday's technology" and President Obama's commitment, as shown in 2015, is 1 million PHEVs.

The tornado threatens Miller's more House agreements and it is not entirely clear whether consumers are willing to pay extra for additional miles.
Electric range provided by PHEVs.
"The trial day is right in front of you," he said . ".
"The challenge here is that you will carry about 300 pounds of the battery after the charge runs out.
Dogs don't hunt.
Reinert cited studies from Carnegie Mellon University and Duke University that were skeptical about PHEV's claims. In a chart-
Carrying extra battery weight means the subframe is larger in diameter, the brake size is larger, and the spring is larger, he said.
"There's a lot of weight penalties, and you always have to pay the price," he said . ".
"When you keep increasing the size of the battery pack, there will be less and less returns.
PHEV's buyers will be trading in Prius and other hybrids, rather than the Hummer, according to Reinert (which further weakens the green advantage ).
Of course, the progress of the battery can greatly reduce the size, cost and complexity of large batteries.
But Miller says battery technology lags behind hydrogen fuel cells.
Toyota plans to launch a 50-mile city electric vehicle (based on a tiny IQ) and a hydrogen fuel in 2012 --
Cell car at the end of 2014 was still 2015.
But reinat lamented the difficulty of charging urban electric vehicles, and Miller questioned energy minister steven Chu's $100 million reduction in hydrogen funding in 2010.
He said the federal government "should not play with technology for political gain.
