The spring of the smart watch has come?

Consumers are once again attracted to the "Apple" to the attention of smart watches, some people are watching.

Optimistic about the Apple's design language, the integration of the industry chain, and so on, most of the people who wait to see the Apple Watch battery endurance. Some well-known investors said that although the introduction of Apple Watch, to some extent, to stimulate the smart watch market, but if the battery endurance problem is not resolved soon, may affect the user's choice.

The spring of the smart watch has come?

As early as Apple Watch, the market has gathered a large number of smart watch products, such as Samsung, LG, Motorola and other companies have already released their own "watch", but the market reaction generally.

Although the smart watch market is a brand new market, the outlook is much better: Global smart watch shipments are expected to grow by 511% in 2015, with Apple Watch global sales up to 15 million, up 55% of the global market.

And from the industry's attitude to the smart watch market, both investors and consumers are more and more positive feedback. But it is premature to conclude that the spring of the smart watch market has arrived. Although the smart watch market is becoming more and more prosperous, the power of smart watch batteries is still a huge "weakness". In the long run, solving this problem requires a certain amount of time and technical breakthroughs.

There are significant differences in the performance of smart watches on the market, with a length of 5-7 days short hours. For smart watches, even if standby can be up to 5-7 days, it is still difficult to meet the needs of ordinary users. After all, smart watches are the first to be watches.

The smart watch market is still in its infancy, and it is unrealistic to want to quickly boost battery life in the short term. Even the decade-old smartphone market has failed to find a better response to the battery's endurance.

Since 2005, lithium-ion polymer batteries have begun to replace ordinary liquid lithium batteries, and since then, the smartphone's battery energy density has made a huge leap. In 2013-2014 years, as many smartphone makers began to build batteries, and the smartphone battery's operating voltage began to rise from 3.7V to 3.8V, smartphone batteries reached a peak over capacity (also called gram capacity, the amount of electricity per gram of battery).

Even so, the smartphone battery has run into a "bottleneck". In the face of the high power consumption of smartphones today, lithium batteries are clearly a bit "powerless".

Of course, smartphone makers are also constantly looking for new ways to improve battery life, such as increasing battery capacity, charging through an external power supply, and even hoping to dramatically boost battery life with new battery technologies such as fuel cells and bio-batteries.

In the development of intelligent manufacturers, the use of smart phone users have been accustomed to "one day" or even "more than a day." However, a smart watch cannot be treated with empathy. And do not mention the "one-day" cumbersome, if it is a smart watch users, who would like to carry an external power supply at any time to charge it? How to make consumers more convenient to use, is the smart watch manufacturers must solve the problem.

"Revelation" brought by pure electric car battery

From the entire intelligent hardware market level, not only smart watches, smart phones, smart cars have also encountered the problem of battery endurance.

In general, the two directions of automobile in the field of Intellectualization are new energy and Internet. In which, pure electric vehicles are typical representative. After all, it has also experienced battery life problems. In recent years, the development of pure electric vehicles, although it can not be said that it has completely solved the problem of endurance, but also has a larger increase. And this, to some extent, may provide some inspiration for smart watches.

At present, most of the pure electric vehicles, are based on gas locomotives installed batteries after the modified models, the general range of mileage is about 100-150 kilometers. The new generation of pure electric vehicles is fully in line with the demand for pure electric vehicles, not based on the transformation of fuel prototype car models, such as Tesla, such as the Sino-German joint venture to create a pure electric vehicle.

Among them, Tesla uses Ni-co-Al lithium battery, the proton is used lithium iron phosphate battery. Tesla's Ni-co-Al lithium battery is lighter than energy and small in size, but there are too many restrictive factors in safety. And teng potential of lithium iron phosphate battery, charge and discharge efficiency is high, the rate of discharge charge and discharge efficiency can reach more than 90%, cycle life and other performance than ordinary batteries more than 4 times times, safety, stability are relatively high.

And what kind of battery is most suitable for pure electric vehicles, these years pure electric vehicle enterprises are also constantly groping. After all, the first consideration of pure electric vehicles is to meet the real needs of users-the use of convenience. On pure electric vehicles, it is high safety, high mileage of the model, can really let users pay.

For example, a joint venture between BYD and Germany's Daimler, the total energy of the lithium iron Phosphate battery pack is 47.5kWh. It is thanks to the advantages of lithium iron phosphate batteries, the energy of the energy mileage can reach 300 kilometers. Covering the entire electric vehicle market, the energy mileage in the same level is the longest pure electric vehicles. If users are just commuting daily, they don't need to worry too much about the endurance.

As for the safety of the pure electric cars that users are concerned about, Proton's battery safety management has also done a better job: lithium battery pack is wrapped in a specially designed battery protective device, protected by a strong aluminum frame, and installed in the body below the most safe parts of the body, thereby enhancing the stability of the vehicle. In addition, the proton is equipped with intelligent current management system, which can continuously monitor the energy flow between lithium battery and power system, ensure that in case of accident, lithium battery will be automatically disconnected, and in a critical state of rapid discharge to safety voltage.

Although pure electric vehicles such as Tengzhong and Tesla are still not "perfect" in their batteries, they have in fact been able to meet the basic needs of most ordinary consumers after years of development. This is precisely what smart watches need to keep working on. And from the perspective, although smart watch or smart hardware market needs to improve a lot of problems, but as long as the real demand for users constantly improve, the next wave of consumer spending boom is also a prospect.
