Why Range Anxiety Is The Mortal Enemy Of EV Efficiency - 24 volt lifepo4 battery pack

Last week, the green car Press was flooded with reports that GM increased the range of electric drives for the 2013 Chevrolet Volt from 35 miles to 38 miles.
The increase is due to better batteries.
LG Chem (OTC: LGCIF), a battery supplier for GM, has apparently increased the bulk energy density of the battery to the point where GM can hold 16 batteries.
Storage space at 5 KW hours can only accommodate 16 KW hours in January 2011.
GM's press release also noted that "the test shows that the degradation of the battery is low and can withstand as low-
30 degrees Celsius, less affected by energy throughput.
"Battery improvement represents volume energy density gain 3, according to my calculator.
In less than two years, 125%, and moderate growth in the cycle --
The performance of life and cold weather.
I was impressed because I knew how hard it was to increase energy density and improve battery performance.
However, this achievement does highlight the unpleasant reality --
Changes in battery performance and a significant reduction in cost are highly unlikely.
The development and commercialisation of batteries is a long and slow process, the difficult and expensive process has nothing in common with the short product development cycle we recognize and love in the IT revolution and the dramatically reduced costs.
The research and development and manufacturing dynamics are very different this time.
The difference is that Professor vazraf Smille called this new power Moore's curse.
With the announcement of GM last week and the launch of Model S by Tesla Motor (NASDAQ: TSLA) this month, now seems like a good time to revisit an issue I discussed in December 2008, most evangelists are still not sure-range anxiety is always the enemy of the efficiency of electric vehicles.
In the financial world, the value of any asset is based on the number of payments that its owner can receive within a given time and the amount of each payment.
Hotel rooms with a daily rent of $1,000 are more valuable than executive suites with a weekly rent of $1,000, and more valuable than apartments with a monthly rent of $1,000.
While living spaces and batteries have nothing else in common, their intrinsic value to owners is based on the same financial iron law.
Full use and daily turnover maximize the value of assets, while inefficient use and slow turnover are barbaric values. In the U. S.
, An ordinary driver travels about 12,500 miles a year on his car, or about 40 miles a day when you explain different weekend driving modes.
Compared to new cars that meet CAFE standards, 40-per car-
Electric mileage daily commute cycle
Mode alone represents a potential savings of 1.
3 gallons of gas, the effective "daily rate" is about $5.
Starting at the rate for the day, I can put on a green eye mask and delve into the operational inefficiencies directly attributable to range anxiety.
Batteries cost money; lots of money.
While GM is quite nervous
Most experts are tight-lipped about battery costs and think Volt's battery pack costs less than $12,000.
In contrast, the battery pack of the Tesla Model S-
It will cost about $45,000.
In most cases, the driver of the Model S
85 will not save more gas than Volt's drive.
Pay $33,000 for electricity
The range that most drivers rarely use is just a bit wasteful.
The first great tragedy is
The only scope, the most excessive
The widely publicized feature in EVland is the enemy of EV efficiency.
When the battery capacity you buy every day does not exceed the capacity you plan to use, the electric drive is the most economical.
Relieving range anxiety with a huge battery pack may feel better, but it can ruin any excuse for efficiency.
The second big tragedy is that the cost of making electric car batteries is $30 to $50 per pound, but it is not worth recycling.
Value of recycled metal in most lithium
The price of ion batteries ranges from $0.
$50 to $5 per pound, but the cost of collection, transportation, primary battery recycling and secondary metal separation and refining exceeds the value of the recovered metal.
Several companies have set up pilot scale lithium-
Ion battery recycling facilities, but these facilities are experimental and the current recycling technology is far from cost-effective --effective.
This range anxiety relieves the efficiency of the battery pack for electric vehicles during battery life, and also leads to unreasonable waste of scarce non-ferrous metals at the end of life.
Although my article seems to draw on the constant vigilance and long-sighted remarks of the Paladin, they are still fiercely, maliciously and occasionally defamatory.
Elon, an efficient car like a Toyota plug.
At Prius, the best is the edge economy proposition, and the most efficient electric vehicle like the Tesla S-Model
This is a waste.
Benjamin Graham once said: "In the short term, the market is like a voting machine, but in the long run it is like a weighing machine. " While Mr.
Graham is talking about the stock market, and his wisdom applies to all markets.
The gospel frenzy of revenge on electric cars can only last for so long.
When consumers and governments begin to weigh the real cost of power-driven and its largely illusory interests, the House of Cards will collapse and investors will suffer.
