Recently, because of my work, I have read a lot of materials about smart grids. The more I know about it, the more I feel that the "king" is not doing business and the industrial chain of several important industries is missing. The industrial potential is not satisfactory, we want to bend. Road overtaking encounters the US group operation, it will be undoubtedly lost in strategy, and the dream is ultimately a fantasy.
Recently, when I talked about reading materials, my leader also talked about a very correct and radiant thing. I would rather spend 50% more time reading some English materials, and I don't want to save the effort to read translated second-hand materials. In line with this principle, I also tried not to mislead you xdjm, and tried to post the name and author of the first-hand material. I hope everyone can do more homework.
1. "US Smart Grid" by Marcy Lowe, Hua Fan and Gary Gereffi is a good material to see electric cars from the perspective of smart gridAmong the entire smart grid layout, electric vehicles are an important part of them, but they are still only a small part of the whole system. From the following figure, electric vehicles are special with "mobile" attributes. Intelligent power terminals are more appropriate. In the environment where Europe and the United States pay more attention to the environment and carbon emissions, it is a dominant environmentally friendly product. In view of the possession of the traditional car in the past, once it still maintains its original usage habits in the future, its energy flow is relatively large. It is more difficult to estimate that if all the cars are really replaced with electric cars, the demand for the entire power will inevitably bring about tremendous changes according to the original model.
The initial calculation is: first confirm the household electricity bill, look at the monthly electricity consumption, and then consider the individual commute and TImes; electricity and mileage coefficient, this electricity load will lead to changes in the overall power consumption. This is a problem facing the power industry all over the world.
Seeing this picture is almost a projection of American industry. I didn't want to understand how Fudan had such a strong professor and could say that engineering students couldn't rely on the big city's heartfelt words. Does the city rely solely on the service industry without industrial support? I tried hard to understand how he learned history. I can't write an article to discuss his topic, stop it.
The only thing I can't understand in the above picture is who is making EV and PHEV. Is it not related to GM and Ford? What's also puzzling is that Better place is included in the Grid interconnect, because the replacement battery can be included in the energy storage unit, so how to guarantee the service life of each battery pack.
Want to know about smart grid companies in the US? Want to know about EV Charging? Look at Appendix A. 125 lead firms in US smart grid and their technology footprints:
Today, I saw Microsoft and Toyota cooperate to build a PHEV database, and see it here. Google has also emerged, and given its autopilot program, everything is possible; the areas of IBM and GE are not surprising. Looking at the complete list, all xdjm, who said that the US manufacturing industry is declining, can try to see if the US is moving in the direction of whether it is moving in a more efficient and valuable direction, rather than staying in place to wait for you to catch up. As we conquered the CRT, they have completed the layout of LCD and digital TV, and will always fall behind.
2. "Vehicle to Grid InteracTIon in the Smart Grid" by Henning Lohse-Busch, Ph.D. is another interesting material to see the smart grid from electric vehiclesWhat I don't understand most is that Japan and its people think of how to use CAN as the interaction between the EV and the grid. This is really the result of automakers' leadership, and the added cost and technical meaningless transit of the entire grid.
Due to the safety requirements of electric vehicles and the need to be compatible with different grid environments, the use of control circuits as a security guarantee, the communication between the vehicle and the grid can be realized by different paths is a very good idea. I can hardly imagine that there is a fixed physical reference. The restraint of the needle will be a hindrance.
