You have to love Elon Musk, he has a set of brass ones!
Remarks come in the wake of Nissan bragging that it is far ahead of competitors
If there's one main factor that is turning people off from truly considering
electric vehicles for their next purchase, it is the price. Thus when Nissan
claimed to have reached production costs of $375/kWh for its upcoming
2011 Nissan LEAF EV, it turned heads. After all, most
auto companies were saying that they hoped to reach $400-$700/kWh with their upcoming models.
Tesla Motors CEO Elon Musk is not impressed with Nissan's claims, though. While he does not comment much on the battery cells themselves, during a call to analysts and investors he blasts Nissan's supporting systems, saying that
they are more primitive than his company's first prototype.
At issue is the fact that the LEAF uses air cooling for its batteries, while Tesla uses a superior liquid heating/cooling thermal management solution. By opting for the cheaper air cooling, Musk says Nissan's battery temperatures will be "all over the place". Worse yet, he says that they will undergo "huge degradation" at colder temperatures, and literally "shut off" at warmer ones. Competitor GM has stated that its
2011 Chevy Volt EV
may have similar issues.
Tesla Motors' current system for the Roadster sports over 6,831 laptop-sized battery cells designed for
automotive use. It packages cells together in modules and then places modules into a full pack. Each module is equipped with liquid cooling and temperature sensors. Firmware controls the rate at which the cooling fluid (or heating in cold weather) is pumped through the system, responding to changes in heat.
Despite having a huge profit margin on its current Roadster, Musk says that his company is "giving up" hopes of overall profitability in exchange for "pretty astronomical growth." Tesla is instead opting to spend up to $500M USD (currently its hoping to stick to under $400M USD) to develop its
new Model S electric vehicle.
Musk says the
new vehicle will sport significant improvements to its battery. It will feature 50 percent more density per module -- meaning that it will pack 3 cells into a similar sized module for ever 2 of the Roadster's pack. It also ditches the expensive all-cobalt electrode in favor of a nickel cobalt aluminum cathode (positive electrode). The new composite cathode will be much cheaper, while not significantly impacting performance.
The company has not revealed the cost per kWh that it's targeting for the Model S. In 2009 the industry average, according to a Deutsche Bank
report [PDF], was $650/kWh, but current orders being placed for the 2011/2012 timeframe are averaging $450/kWh. The rapidly dropping prices are helping to cut the cost of laptop batteries as well, which are priced at $350/kWh,
according toLG Chem subsidiary
Compact Power’s CEO Prabahkar Pati. Pati says that low price is a sign of things to come for the auto industry.
Tesla Motors plans on having an "Alpha" version of the Model S built later this year. That version will be 80 to 90 percent complete in terms of production intent. Then next year it will build a "Beta" version, which will be 99 percent complete. The production Model S is launching in 2012 priced at $57,400 USD.
While that price may seem high, price inflation may make it more competitive. Some dealers of the upcoming Volt EV are reportedly adding $10,000 to $20,000 USD markups on to its base price, raising the cost to
as high as $61,000 USD before tax credit.
Still pressure is on for Tesla, which lost $38.5M USD in its last fiscal quarter, bringing its total losses for the year to $68M USD -- over $10M USD more than it lost
all of last year. The company has an upcoming contract with Toyota to
produce an electrified RAV4 that also promises great future payoffs, but at the present is sapping cash.
