In cobalt acid lithium battery woes Tesla is the road to the future

Detroit last year to $17 billion in debt bankruptcy in July, one hundred, "auto city" self-effacing voice has not fallen settles, based in silicon valley, Tesla, for use Cobalt acid lithium batteries To tender, such as sheep's electric car modification sex Wolf and attracted a lot of attention.

With mature electromechanical integration technology, silicon valley as a holy site in the IT industry, properly for Tesla cover on the aura of the Internet, minimalism, user level localization, the terminal connection, Tesla CEO elon musk Allen is not only a master of resource integration and marketing, was a great practitioner, Tesla Motors directly to the advent of electric cars and toy impression from the low end of the mud, subsequent models but also relies on the dynamic Model - S body lines and hundreds of kilometers speed record of 3.9 seconds, the silicon valley to Detroit's successor.

Indeed for the electric car companies in silicon valley provides unprecedented intelligence operation experience, Tesla change the button in the gasoline vehicles and other electric car brand design, with a touch screen instead, let the user feel is still in the process of driving sliding on apple phones capacitance screen, strong scent of science fiction for Tesla electric cars, high-end positioning and increased a lot of chips. Using the touch screen, the driver can be completed including the most basic navigation, listen to music, adjust temperature, adjust the seat position, even can also surf the Internet.

But these intelligent operation for a car, are still in a relatively shallow level, through the touch screen operation Tesla, the driver can be more easily to realize the skylight and window switches, monitor mileage, even on the wheel control screen operation, but in the more tight security and accident treatment market, Tesla do far from gm's On star wonderful.

Integrated wireless communication and globalspecial positioning technology of remote control system, can not only detect fault and repair service, remote sensing device also can pass the car body week, realize the automatic alarm after the accident. From this perspective, On star shape is more like the description of vehicle network, a complete set of terminal collection, data collection, data processing and feedback system.

That is to say, the smart car most of the time just Tesla with customized marketing ma3 jia3 in silicon valley, and to feed the owner behind marketing nerves or Tesla battery technology.

Cobalt acid lithium batteries cannot alter nature

2008 Tesla Motors USES the Panasonic NCA series, aluminum nickel and cobalt system provided by the 18650 small battery, single battery capacity is 3100 MAH, the battery is no stranger to say, a laptop computer and cell phone batteries are all members of the family. Battery is recognized in the industry18650 battery Not suitable for Power battery The cobalt acid lithium battery with large current discharge ability, such as poor safety performance and cycle life short faults.

Tesla's math magic will be divided into 7000 pieces of cobalt acid lithium battery block, layer, three levels of management, 69, 18650 got behind and a piece of batteries, 9 cell block series into one layer, and 11 layer series again into the cell. If you want a bigger power output, number of cells is likely to be tens of thousands of, once appear, emergency brake, such as high power discharge or low temperature, impact, piercing, these tens of thousands of pieces of battery is like a time bomb.

It is worth mentioning that Tesla appeared this kind of pure electric cars, more stable performance lithium iron phosphate batteries Technology is still immature, Tesla's choice is not much, but at the time of the Tesla roadster, determines its users is not sensitive to circle life and discharge capacity, as for the safety performance, Tesla in nearly 7000 battery unit and each battery level set up insurance device, once detected the battery temperature too high or too much electricity, immediately disconnect the output.

The battery management doesn't seem to be reliable, however, since 9 months 6 spontaneous combustion accident recalled 439 vehicles is evident in the data. Previous spontaneous combustion accident, musk were given the interpretation of the battery pack was pierced, and because the car warning system in place, all from the casualties, and Tesla electric car spontaneous combustion in Canada in February, when the owner is not to make any high strength automobile operation, just to drive back to the garage.

These accidents by Tesla's public relations channel, provides the driver with a temporary homogeneous security and beyond the power of other electric cars two times, but the driver has left a question mark in my heart, a battery management software can really resolve cobalt acid lithium batteries unstable chemical properties? What's more, the Tesla electric consumption crowd also focused on the rich, who tend to have much money for rotation, Tesla only used in limited situations, under the condition of market is far from universal, though Tesla battery has a high efficiency range and strong power, but hidden safety problems, or would you let the cockpit bus staff concerns.
