Description

A rolling side brush charging device for electric vehicles with unlimited long-range endurance

technical field

The invention relates to the technical field of mobile charging and power supply for electric vehicles, in particular to a rolling side brush charging device for electric vehicles with unlimited long-distance endurance.

Background technique

Today, the world is generally facing the severe situation of environmental protection pressure and energy crisis: First, in terms of environment, first of all, urban smog is becoming more and more serious and urgently needs to be prevented and solved. Secondly, the global greenhouse gas emissions are rising, and the "Paris Climate Change Agreement" requires that greenhouse gas emissions not continue to increase. The second is that fossil energy is facing depletion. Although the newly discovered shale gas and combustible ice have a large capacity, mining is difficult and costly, and it is difficult to use in the short term. New energy must be developed. Electric vehicles have the advantages of no pollution, low noise, high energy efficiency, simple structure and convenient maintenance. It is imperative to develop electric vehicles to replace fuel vehicles. In recent years, the electric vehicle industry has developed rapidly under the advocacy and support of various countries, effectively solving the short-distance travel by car, but the long-range endurance of the power battery is insufficient, and the charging speed is not fast, which leads to the mileage anxiety problem that has not been well resolved. It has become the biggest technical bottleneck in the development of electric vehicles and affects the popularization of electric vehicles.

At present, the general idea to solve the problem of mileage anxiety is: on the one hand, increase the energy density of the battery to actively increase the cruising range; on the other hand, extensively build charging piles to try to increase the charging speed of the battery. This kind of thinking seems to be able to solve the problem, but in fact it still cannot fundamentally solve the problem of mileage anxiety: because the battery capacity and charging time are a contradiction, extending the cruising range by increasing the battery capacity is bound to prolong the charging time relatively. The advancement of fast charging technology is conducive to shortening the charging time, but fast charging will reduce the number of battery cycles, shorten the battery life, and increase safety risks. Moreover, it is also restricted by the load of the power grid. It is impossible to speed up indefinitely. There must be a limit that cannot continue to break through. Therefore, it is unrealistic to expect to achieve the same convenience as refueling by continuously increasing the battery capacity and increasing the charging speed. Even if there is such a technical product in theory, it cannot be promoted: because the cost of large-capacity fast-charging vehicles is extremely expensive, Tesla is a vivid example, only the rich can enjoy and afford it, and it is difficult to become a national car Accepted by the public. This conventional idea essentially follows the idea of parking and refueling fuel vehicles to solve the problem of charging electric vehicles. It hopes to build charging piles like building gas stations to solve the problem of vehicle charging. However, the existence of electricity and oil is different, resulting in battery and fuel tank charging Note that the effect is definitely different. The fuel tank has no specific restrictions on the refueling speed, but the battery has many restrictions on the charging speed. Too fast charging will reduce the number of battery cycles and shorten the service life. Moreover, it is also restricted by the load of the power grid and cannot be increased at will as imagined. charging speed. It is difficult to store electric energy like fuel first, and then refill the stopped vehicles as conveniently as refueling. In short, parking and charging will never be as convenient as refueling. This kind of thinking is difficult to solve the problem of mileage anxiety. If you put aside this solidified thinking, it is not difficult to find that electric energy transmission is obviously different from fuel transmission. Fuel can be sent to gas stations by tankers to realize fixed-point refueling when parking, while electric energy has excellent mobility. The advantage is that it can be conveniently transmitted through the grid and It can be picked up whenever you need it, and the flow is continuous. You don’t have to stop and refuel like refueling. You can move and swipe from the power grid like a high-speed rail to realize charging while driving. If the charging process is also the driving process, you can Avoid the anxiety of parking and waiting. As a result, mobile charging is more convenient than parking and refueling. This way, the problem of charging is easily solved, and mileage anxiety is no longer a problem. Considering that the actual daily mileage of nearly 80% of car users is usually less than 80 kilometers, charging piles can be used for slow charging at night and more use of valley power if they do not travel long distances. With the help of the mobile charging and power supply system of the highway network, the insufficient electric vehicles have cleverly solved the problem of long-distance unlimited battery life.

In the future, the continuous improvement of battery energy density and fast charging technology will be more conducive to the promotion of mobile charging technology. If it can be fully charged in 5-10 minutes without affecting battery safety, then the battery capacity of the vehicle will no longer need to pursue 500 kilometers or even Longer cruising range, maybe 100-200 km cruising range is enough, then the vehicle cost will be greatly reduced, and it is no longer a dream to launch a national car with less than 100,000 yuan. Electric vehicles are cheap, convenient and environmentally friendly. A new era of blowout development is just around the corner.

Chinese patent application CN201410795407.8 discloses an electric vehicle capable of unlimited long-distance battery life and its tracked mobile charging and supplying system. The system mainly uses two wear-resistant conductive slide rails set in parallel to externally connect the road network power supply from the expressway to realize power supply. With the help of the expressway network to build a charging and power supply system, through the trackless electric vehicle running on track, it can not only use the power supply of the grid for battery life, but also It can be charged and stored synchronously, so as to realize the unlimited long-distance continuation of electric vehicles; the above-mentioned device provides a solution to some problems, but when the electric vehicle with unlimited battery life and the highway network are brushed, the side brushing is used, which is harmful to the electric vehicle. The equipment requirements of the brushing mechanism and the brushing mechanism are relatively high, and the structure is complex, which needs to be improved urgently.
