3.7 volt 18650 lithium battery

Fast charging technology VS 3.7 volt 18650 lithium battery swap station! Who can really solve the range anxiety problem of new energy vehicles?

The range of electric vehicles has always received widespread attention from all parties. If you want to completely solve the range anxiety problem of electric vehicles, it is probably difficult to achieve it directly by relying on the existing technical environment and conditions, so you can only settle for the second best and think of solutions in the energy supply of batteries!

At present, the solutions on the market are mainly fast charging and 3.7 volt 18650 lithium battery swapping. Who can really solve the range anxiety problem of new energy vehicles?

Fast charging technology

As the name suggests, fast charging technology is to quickly charge your car through high voltage and high current.

3.7 volt 18650 lithium battery swap station

As the name suggests, it is to directly replace your 3.7 volt 18650 lithium battery in the 3.7 volt 18650 lithium battery swap station, similar to the 3.7 volt 18650 lithium battery replacement of mobile phones. At present, it only takes about three to five minutes to replace the 3.7 volt 18650 lithium battery at the Weilai Automobile 3.7 volt 18650 lithium battery Swap Station from start to finish.

Fast charging technology VS 3.7 volt 18650 lithium battery swap station

From the perspective of efficiency, it takes 30 minutes for general DC fast charging technology to charge 80% of the power, while the 3.7 volt 18650 lithium battery swap mode only takes about three to five minutes, which is shorter than the time required by fast charging technology.

At the same time, from the perspective of power utilization, the 3.7 volt 18650 lithium battery swap station can make full use of the valley electricity at night to charge the 3.7 volt 18650 lithium battery in a concentrated manner, which can effectively reduce the pressure on the grid operation during the day, and the advantages of peak shaving and valley filling are obvious.

However, from the perspective of operability, fast charging technology is what the market really needs.

Because the 3.7 volt 18650 lithium battery swap station model also faces great problems, such as: the construction cost of the 3.7 volt 18650 lithium battery swap station, the 3.7 volt 18650 lithium battery swap 3.7 volt 18650 lithium battery standard, and the high operating cost, which restricts its development.

In particular, the lack of 3.7 volt 18650 lithium battery standardization directly determines that the 3.7 volt 18650 lithium battery swap model cannot be fully popularized. It is understood that at present, the standards of electric vehicle power lithium-ion batteries of various domestic manufacturers are different. Even if they are of the same brand and the same car series, the 3.7 volt 18650 lithium battery specifications may be different due to different listing times. Since 3.7 volt 18650 lithium battery technology is the core secret of each company, it is impossible to require 3.7 volt 18650 lithium battery companies to unify 3.7 volt 18650 lithium battery standards. In this way, in addition to being able to achieve the same size, the capacity of the 3.7 volt 18650 lithium battery cannot be the same at all. No consumer is willing to go to a 3.7 volt 18650 lithium battery swap station to replace a power lithium-ion 3.7 volt 18650 lithium battery pack with a smaller capacity than the original one.

On the other hand, except for the current efficiency, charging technology has advantages over the 3.7 volt 18650 lithium battery swap mode: for example, convenient charging and cheap electricity are acceptable and demanded by the public.

The author believes that based on the existing technical conditions and user needs, both of these can meet the market needs and can solve the range anxiety of new energy vehicle users. However, in the final analysis, no matter what method is used, as long as consumers approve, the problem can be solved.
