Tesla's battery is world famous for its breakthrough in electric vehicles. The idea is not new and has been mastered for many years by leading automotive companies. However, American designers were able to optimize this direction, taking into account the interests of the consumer. To a large extent, this has become possible due to innovative energy supply systems focused on the complete replacement of conventional internal combustion engines. Consider the features and varieties of this drive.

Application

The development of fundamentally new types of li-ion batteries is due to the tasks of improving the performance of electric cars. In this regard, the basic line of the Tesla S model is focused on providing the vehicle with innovative power sources. A feature of lithium-ion batteries was the introduction of a combined mode of operation, in which the alternation of energy supply from an internal combustion engine and AB is allowed. At the same time, the company's engineers continue to develop machines that are completely independent ofthe usual type of fuel.

It is worth noting that engineers are not limited solely to the creation of power elements for road transport. Several versions of Tesla batteries have already been released for domestic and commercial use. If the option for an electric car is aimed at maintaining the operation of running gear and on-board electronics, then stationary storage modifications are positioned as autonomous sources of electricity. The capabilities of these elements make it possible to use them for servicing home appliances. Additionally, research is underway on the accumulation of solar energy. Works are still under development.

Device

Tesla batteries have a unique structure and way of placing active components. The main difference from the analogue is the lithium-ion configuration. Similar elements are used in the design of mobile devices and electric tools. Tesla engineers first used them as batteries for cars. The whole block is divided into 74 compartments, which look like AA batteries. Depending on the configuration of the battery, it includes from 6 to 16 segments in the design. The positive charge comes from the graphite electrode, the negative moment comes from several chemical components, including nickel, cob alt and alumina.

Tesla batteries are integrated into the car by fixing them on the bottom of the vehicle. This arrangement provides a low center of gravity of the electric vehicle, increasingcontrollability. Special brackets are used as fasteners. Currently, there are not many such solutions, therefore, the specified part is often compared with a traditional battery.

Important points regarding security and placement. The first factor is guaranteed by the high-strength housing in which the battery is mounted. In addition, each block is equipped with a fence in the form of metal plates. In this case, not the entire internal part is isolated, but each element separately. It should also be noted that there is a plastic lining that prevents water from getting inside.

Tesla battery specifications

The most powerful battery for an electric car consists of 7104 small batteries. Below are the parameters of the specified element:

  • Length/thickness/width - 2100/150/1500 mm.
  • The electrical voltage indicator is 3.6 V.
  • The amount of power generated by one section is identical to the potential of a hundred personal computers.
  • Tesla batteries weigh 540 kg.
  • The travel time on a single charge on an average element with a power of 85 kWh is about 400 km.
  • Speed up to 100 km/h - 4.4 seconds.

With these characteristics, a reasonable question arises,how durable these structures are, because high performance implies intensive wear of active parts. It should be noted that the manufacturer gives an eight-year warranty for its products. Most likely, the working life of the batteries in question will be the same.

While the owners of electric machines can not confirm or deny this fact. In addition, there are research results that indicate that the battery power parameter is characterized by its moderate loss. On average, this figure is about 5% per 80 thousand kilometers. There are other facts that indicate that the owners of the specified vehicle regarding problems in the battery compartment are turning less and less as new models are released.

Tesla Battery Capacity (Model S)

It is necessary to evaluate the capacitive characteristic of batteries taking into account the development of production. During the improvement of the line, the indicator varied from 60 to 105 kW / h. Official information indicates that the peak battery capacity is about 100 kW / h. According to the reviews of the owners, the real parameter will be somewhat lower. For example, an 85 kW Tesla battery actually produces no more than 77 kW.

History also provides reverse examples, confirming the excess of the volume. There are cases when a 100-kilowatt battery was endowed with a capacity of about 102 kW. From time to time, contradictions are found in the definition of active nutritional components. Mainlydiscrepancies are observed in estimates of the number of block cells. This is due to the fact that the battery is constantly being upgraded and improved, equipped with innovative elements.

The manufacturer claims that every year updated modifications undergo transformations in electronic parts, cooling system, architecture. The ultimate task of designers is to achieve the highest possible quality characteristics of the product.

Power Wall Version

As mentioned earlier, along with the release of Tesla car batteries, the company produces household versions of energy storage devices. One of the productive and latest modifications was the lithium-ion version of the Power Wall. It is designed to generate energy as a permanent source or is operated as a standby structure similar to an autonomous generator. The model is presented in several variations, differing in capacity and serving to perform certain energy tasks. The most popular versions are 7 and 10 kWh units.

Regarding the operational parameters, it can be noted that Power Wall has a power of 3.3 kW with an operating voltage of 350-450 watts, a current of 9 A. The weight of the structure is 100 kilograms, therefore, its mobility is out of the question goes. However, as an option, for example, for summer cottages, the block is quite suitable. The unit is transported without problems, since the designers pay great attention to the mechanical protection of the body part. Certain disadvantages include a long period of battery charging.(12-18 hours), depending on drive modification.

Power Pack Model

This system is based on the previous version but is commercially oriented. This means that such a Tesla battery is used to service enterprises. It is a scalable energy storage device that provides increased system performance at the target site. It should be noted that the battery capacity is 100 kW, while the indicated capacity does not apply to the maximum indicator. Engineers have provided a flexible design for the aggregation of several units with the possibility of obtaining a value from 500 kW to 10 MW.

Single modifications are also being upgraded in terms of quality of operation. Official information has already been received about the appearance of the second generation of commercial batteries, in which the power parameter was 200 kW, and the efficiency approached 99%. The specified energy storage device differs in technological indicators. To expand the volume, the developers used a reversible inverter.

This innovation made it possible to increase the power and performance of the system at the same time. The company plans to develop and implement Power Pack cells in the design of additional solar components such as Solar Roof. This approach allows you to renew the energy potential of the battery not through special lines, but through free solar flow in continuous mode.

Production capacity

According to the manufacturer himself, innovative batteries are manufactured at Tesla's own Gigafactory. The assembly procedure was organized with the participation of Panasonic representatives (delivery of components for block segments). The specified enterprise produces the latest designs of power supply systems focused on the third generation of electric vehicles Model.

It is assumed that the total number of products produced at the maximum production cycle will be up to 35 GW / h. It is worth emphasizing that the indicated volume is half of all the parameters of batteries produced in the world. Current maintenance is carried out by a team of 6.5 thousand people. In the future, it is planned to create an additional 20,000 jobs.

Among the features are a high degree of protection against battery hacking. This eliminates the possible risks of filling the market with counterfeit variations. In addition, the production procedure itself involves the participation of high-precision robotic technology in the process. There is no doubt that only corporations of the Tesla level are able to display all the technological production nuances at the present time. Most interested organizations do not need plagiarism, as they are intensively developing their own developments.

Pricing policy

The cost of the Tesla battery is also constantly changing due to cheaper production technologies and in connection with the release of updatedcomponent parts with high performance parameters. Two or three years ago, the type of accumulative device under consideration was sold within 45 thousand dollars (about 3 million rubles). Now the blocks have a price of about five thousand dollars (330,000 rubles).

Approximately the same cost for home analogues of the Power Wall configuration. The most expensive versions include a commercial battery. For example, the first generation of the specified device can be purchased for $20-25,000 (approximately 1,327,000 - 1,650,000 rubles).

Competing modifications

Tesla is not a monopolist in the production of li-ion batteries. Despite the fact that other brands are not so well known on the market, their parameters are quite competitive. Among the popular representatives:

  • The Korean corporation LG produces Chem Resu drives, which are analogues of the Tesla PowerWall (a 6.5 kWh system costs about 4 thousand dollars or 265,000 rubles).
  • The product from Sunverge has a power range from 6 to 23 kW / h, is characterized by the ability to monitor the charge and connect to solar panels (the price is 10-20 thousand dollars or 665,000 - 1,327,000 rubles).
  • ElectrIQ sells household storage batteries with a capacity of 10 kW / h (together with the inverter, the product will cost $ 13,000 or 865,000 rubles).
  • Among automotive competitors, firms such as Nissan, Mercedes stand out.

The first auto giant produces a series of XStorage batteries (workingvolume - 4, 2 kW / h). The nuances of this modification include a high level of environmental safety, which fully complies with international standards for the production of passenger cars. Mercedes produces compact versions of 2.5 kW / h. At the same time, they can be combined into increased productive systems with a capacity of 20 kW / h.

Features

Tesla electric car batteries and their household counterparts are not very affordable for the mass consumer. With Power Wall systems, the situation is somewhat changing due to cheaper components. But the idea of aggregation with blocks of solar panels cannot yet be successfully implemented due to the high cost. Undoubtedly, the possibility of accumulating a free energy source is beneficial for consumers, but the purchase of such structures is beyond the reach of most interested users.

A similar story with other alternative drives, the principle of operation and use of which gives a lot of advantages, but requires the use of high-tech devices and devices.

Result

In the battery market for electric vehicles, Tesla is the undisputed leader. This is largely due to the use of innovative equipment in the production of environmentally friendly transport. At the same time, the engineers of the leading company face certain obstacles. For example, the Model S series with lithium-ion cells is criticized for poor protection against the ignition of power cells.

Howeverdesigners constantly improve their models and treat criticism constructively. For example, after the only AB fire in the history of electric vehicles, cars began to install a hollow aluminum beam (to protect against obstacles on the road surface), a shield made of pressed aluminum and a titanium plate. Everyone who bought cars before this improvement is offered to complete them for free at service stations.
