At the end of July, #Tesla released its fourth #model Model 3, the mileage of 354 km and 499 km , Which the lowest price is 35,000 US dollars, so that #Model3 is most popular so far .

It is worth noting that the key to making Tesla launch such a electric car is that it uses a upgraded version of the battery- 21700 battery.


As with the #18650 battery, the Tesla #21700 battery is also a kind of cylindrical #lithium #battery. "21" means that the battery has a diameter of 21 mm, "70" means a height of 70 mm, and "0" represents a cylindrical type battery.



Why is the 21700 battery? #Industry analysts believe that: 21700 type cells #energy #density #higher than the 18650 , and after the cost of #pack will be reduced. Choose 21700, not its absolute performance is better than other models, is a combination of #physical and #economic results of the balance.



Earlier this year, Tesla officially announced the joint development of new 21700 battery with #Panasonic began small batch #production, the end of the year will be large-scale production plant in the #supply of Model 3.


The #advantages are obvious, but the #shortcomings worthy of vigilance

#21700 has three major advantages. Monomer and group energy #density are greatly improved, for example, from the 18650 model to switch to 21700 models, the #cell #capacity can reach 3 ~ 4.8Ah, a substantial increase of 35%, into Group after the energy density is still increased by 20%.


If you continue to increase the size of the battery , safety and adaptability will be reduced, invisible to increase the new energy vehicle safety risks and design difficulties, which is why the larger size of the cylindrical battery 26500,32650 and other large scale to occupy the mainstream market the reason.



In theory, compared to 18650 #batteries, 21700 battery life is shorter, the same capacity charging time is longer and lower security. For electric #vehicles, the safety is always the first, in order to avoid high battery #temperature rise is too high, the battery cooling #system must be designed more reasonable.



Can It replace 18650?



In view of the 21700 battery's many advantages, coupled with Tesla's huge industry influence, which battery is likely to become the next #cylinder battery development trend.

As the 18650 battery has a long history of development and accumulation, strong adaptability, the formation of a large market #space and #application, in addition to the field used in electric vehicles, but also in the notebook computer, 3C digital, UAV, power tools And other areas .


The vast majority of production lines are set for the production of 18650 batteries, however, the new energy automotive market in the fast-moving, end consumer market has a pressing demand for life, it determines the manufacturers will give priority to choose high density, comprehensive performance better Battery, and the policy is also adjusted for the market changes.



Today, #Tesla has to carry the banner of the first burst into the 21,700 battery battlefield, the domestic battery manufacturers have to choose to follow, and some still wait and see. This may be a gambling or a feast.

The first low-temperature battery born, electric #vehicles will not be afraid of cold?



#Electric #vehicle afraid of "cold", in case of cold, the #battery performance will be greatly reduced. This has become a major obstacle to the development of electric vehicles. August 31, the world's first low-#temperature battery products come out. It can be heated from minus 30 degrees to more than 0 degrees, thus activating the normal application of #power #batteries.


"In the cold weather, the electric vehicle mileage can be reduced by 40% to 50%, and below zero can not charge, which makes it a 'greenhouse flowers'." One of the technical team leader, Beijing Polytechnic University Professor Sun Fengchun told the technology Daily reporter, usually to the battery "warming" method is outside the heating, but this way not only high energy consumption and the effect is not ideal.



Product research and development team from the Beijing Institute of Technology, CITIC Guoan UNITA Power Technology Co., Ltd. and the United States EC Power company. Technical staff to use the principle of metal wire heat generation, in the batteries on the installation of nickel foil. After the power, the nickel foil produces heat, so that the battery internal temperature. To a certain temperature, the foil will automatically disconnect, to ensure safety.

"In the minus 30 degrees of the experimental environment, the application of the technology of the battery only 30 seconds, you can quickly heat up to zero, so that the discharge power increased by 6 times, charging power is increased more than 10 times." Sun Fengchun told reporters, This operation does not change the original structure of the battery, and the transformation of low cost, suitable for lead-acid batteries, lithium batteries and other types of batteries.


This battery will be the main service in 2022 Beijing - Zhangjiakou Winter Olympics. "During the Olympic Games, the outdoor temperature may be as low as minus 30 degrees, low-temperature battery to ensure the normal operation of the vehicle." Sun Fengchun said.



He revealed that in December this year, the team will develop a low-temperature batteries equipped with buses, buses and cars and other three types of vehicles, and next year before the Spring Festival in the low temperature cold area to complete the prototype test.

Shocked: the most costly #battery #capacity of #electric #scooter is this little action ?



With the electric #vehicles in the domestic market hot up, more and more users feel the convenience and benefits of electric vehicles, users of their own electric #scooter battery life, how to protect the battery life and electric bike battery charging market Need to understand.


So, for their own vehicles, in the end charge a few hours the best? In fact, also need to vary by vehicles. And for the electric #car battery power consumption of almost the state, generally need to #charge about 8 hours.



In addition, there is a situation that is the electric motorcycle when the charger prompts the power is not full of the state, this time the best rush about 1 hour or so, can not overcharge.


And for many users are worried about the electric #pedelec to avoid electricity consumption is too fast and want to use the possibility of longer life, there are some small suggestions, such as not fierce start, uphill not strong to #power, not #overload, no #brakes, Can not #overcharge, not #exposure, timely #charging and attention to heat and other details.

only from the details concerned about the bike, in order to allow electric car #pedal #batteries #akku #ebike #battery, #motor and life is guaranteed.
