Wireless charging for the automotive industry or for the next hot spot
According to the news, Toyota is testing the wireless charging system in Aichi Prefecture, Japan, which is “burying the wireless charging system into the induction coil under the ground. After the vehicle is aligned, it is charged at 85 kHz, 200 volts, and 20 million watts. The system, jointly developed by Toyota Motor and the Massachusetts Institute of Technology, can provide "'medium distance' (distance between coils can range from a few centimeters to several meters) wireless charging. "Toyota will further optimize the system so that it can eventually reach the stage of commercialization.
Concerned about wireless charging technology for many years, I talked about this in many articles, this technology in a U.S. university experiment, was installed on a specific route, and then verified how to go without a battery. In the case of electric vehicles, of course, as a mainstream car manufacturer to verify and start to apply, such things are still relatively small. As a leading enterprise of new energy vehicles, applying this technology is likely to give the entire industry new The field of wireless charging for energy vehicles brings a new round of hotspots. I discuss the opportunities for this technology and the possible future direction of operation.
First, wireless charging has the potential to "get rid of battery constraints."
Wireless charging is through electromagnetic conversion, so as to cancel the comfortable connection between objects and objects by using electrical energy that was previously transmitted through the cable. Without this connection between cables, it is basically to give more freedom to electric vehicles. This is what the electric car needs most at present.
At present, in order to solve this dilemma, the use of secondary energy storage and transportation to supply the operating power of electric vehicles, basically the most hot Tesla car, can not avoid the huge number of battery arrangements around their chassis, in this Under the circumstances, we always see the prospect of an electric car as if it were a transparent piece of glass: "It's not a good applause."
Therefore, we see that everyone’s expectation for the battery industry is very high. At the 4th International Conference on New Energy Vehicles organized by the first electric vehicle, investors participating in several investment companies are eager to invest in the battery industry. One key point, is there any other way to give this aspect to the past?
Last year, the technical suspicion that I talked about listed "long-range wireless charging" as the first promising vehicle change technology in the future. Of course, this technology has nothing to do with the current wireless charging technology. What kind of relationship does it have? It is still difficult to define the point. Perhaps the electromagnetic world that we can currently see is not yet possible to support remote wireless power supply. However, in the physical world and related equipment preparation, this capability cannot be underestimated. Sex can happen at any time.
If remote power supply is not available, we can talk about the possibility of another aspect. After a U.S. university installed a wireless charging device on a section of road, its own electric car could drive while charging on the road. This technical difficulty is limited and may be relatively high, but a way has been found to overcome the constraints of the car battery.
Also, it is worth mentioning that everyone knows that the construction of highways is an infrastructure construction. Since governments of various countries are willing to develop electric vehicles, let them go to this matter should not be excessive, and how electric vehicles can reduce the burden of batteries. In terms of the overall costs, it is basically possible to make a 50% discount within the current price range. At the same time, the weight is also greatly reduced, and it is extremely important that our consumers are most worried about the fire and other things that are basically related to new energy vehicles. Dissociated from the relationship, these vehicles are absolutely safer than existing vehicles. Think about it carefully. These are the new energy vehicles that we really are looking forward to. These are the wireless energy transmission technologies that bring us, and then look back. Is it right? The direction that many investors pay attention to now is biased. If the author goes to get a wireless energy transmission equipment company, do you want to follow the investment?
Second, mid-range wireless charging increases parking lot charging execution opportunities.
Wireless Charging Like the cordless phones of the past, short-range wireless charging was of little significance, but everything started from a short distance. From the initial cordless phone to the last mobile phone, and the current mobile Internet, this change of our life took time to accumulate. .
However, many people may have already considered a difficult problem. How will the construction of charging stations for new energy vehicles be constructed? If new energy vehicles are to be popularized, how do more residential areas for urban residents build charging stations? First, the parking space is insufficient, and then there are How to carry out the recharging of the charging piles in the parking space is a small area in itself. There is indeed a difficulty in building a charging pile and related wiring harnesses. Therefore, during the implementation of the policy, we can see that the government is escaping this matter and they say that development has occurred. Public car, because the parking location is relatively large, can solve these problems.
However, we know that because of the mere use of public transport, our new energy automobile industry has no room to survive. This cake is too small. A small one cannot support so many people. Therefore, when it comes to private users, we must find a solution to the problem. The user's charging problem.
The current wireless charging technology is not yet capable of realizing remote charging, but "middle distance" charging is already available. Although there is a problem with long distance power supply for the entire route, short-range wireless charging can also be supported, so some new construction is underway at the moment. A certain percentage of wireless charging parking spaces are built in the community or on the parking lot. Normally, new energy vehicles can be used and traditional vehicles can also be used. These applications are a good breakthrough point for the moment.
Third, the addition of unfamiliar industries reflects the "new" of new energy.
Prior to thinking about the concept of new energy vehicles, in fact, new energy vehicles can not really be considered "new", electric cars appear as much time as traditional vehicles, but lost in the initial confrontation, and then the traditional vehicle rule The transportation sector has become a “traditionâ€. Now that the situation has changed, new energy vehicles have become “new energyâ€. If they are discussed from the present, they cannot be called “new†because of the introduction of hybrid vehicles from Toyota in 1997. Now it has sold millions of vehicles and it has gone through more than a decade. At this time, it is still called "new." The reason is not the concept of vehicles, but the industry has new blood from time to time to join, and some technologies , Similar to wireless charging light technology belongs to a cut-in point.
Therefore, we hope that more and more industries, including various industries such as electromagnetics, will come together and create a truly new concept. These are the new energy we expect.
