Description

Rolling side brush charging device of unlimited long-distance endurance electric automobile

Technical Field

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

Background

Nowadays, the global face is the severe situation of environmental protection pressure and energy crisis: firstly, in the environmental aspect, the urban haze is in need of prevention and treatment increasingly and urgently. Secondly, the whole global greenhouse gas emission is increased, and the Paris climate change protocol requires that the greenhouse gas emission is not increased any more. And secondly, fossil energy is exhausted, and although newly found shale gas and combustible ice are not small in capacity, the shale gas and combustible ice are difficult to exploit and use in a short term, and new energy needs to be developed. The electric automobile has the advantages of no pollution, low noise, high energy efficiency, simple structure, convenient maintenance and the like, and the development of the electric automobile for replacing a fuel automobile is imperative. In recent years, the electric automobile industry is rapidly developed under the support of the advocation of various countries, the short-distance travel by bus is effectively solved, but the problem of mileage anxiety caused by insufficient long-distance endurance and low charging speed of a power battery cannot be well solved all the time, the electric automobile industry becomes the largest technical bottleneck of electric automobile development, and the popularization of electric automobiles is influenced.

The conventional thought for solving the problem of mileage anxiety at present is as follows: on the one hand, the energy density of the battery is improved, the endurance mileage is actively increased, on the other hand, the charging pile is widely built, and the charging speed of the battery is improved. This idea seems to solve the problem, but still does not substantially solve the problem of range anxiety: because the battery capacity and the charging time are one spear body, the endurance mileage is prolonged by increasing the battery capacity, the charging time is certainly prolonged relatively, although the charging time is shortened by the technical progress of quick charging, the battery cycle number is reduced by the quick charging, the battery life is shortened, the safety risk is increased, the charging is limited by the load of a power grid, the charging cannot be accelerated infinitely, and a limit cannot be broken through continuously, so that the assumption that the charging is as convenient as the refueling is unrealistic to be achieved by continuously increasing the battery capacity and continuously increasing the charging speed. Even if such technical products are theoretically available, they are not generalizable: because the manufacturing cost of the large-capacity fast-charging vehicle is extremely expensive, Tesla is a fresh and alive example, only rich people can enjoy and consume the vehicle, and the vehicle is difficult to be accepted by the public as a national vehicle. The conventional thought is that the electric vehicle charging problem is solved by the thought of parking and refueling of a fuel vehicle, a charging pile is expected to be built to solve the vehicle charging problem like building a gas station, but the existence forms of electricity and oil are different, so that the charging effect of a battery and a fuel tank are definitely different, the fuel tank has no specific constraint on the refueling speed, but the battery has a lot of constraints on the charging speed, the cycle number of the battery can be reduced and the service life can be shortened due to too fast charging, and the charging speed cannot be freely increased as imagined due to the limitation of the load of a power grid. The electric energy is difficult to be conveniently filled into the stopped vehicle like fuel oil after being stored firstly, and then the stopped vehicle is filled with the electric energy like fuel oil, in a word, the stopped vehicle can not be conveniently filled with the electric energy like fuel oil, and the idea is difficult to solve the problem of mileage anxiety. If the solidification thinking is left, the fact that electric energy delivery and fuel delivery are obviously different is not difficult to find, fuel can be delivered to a gas station through a tank car, parking fixed-point filling is achieved, electric energy has excellent fluidity, the advantages that the electric energy can be conveniently transmitted through a power grid, can be taken at will and continuously, parking filling is not needed to be adopted like filling, brushing can be carried out from the power grid like high-speed rails, running and charging are achieved, if the charging process is the running process, anxiety of parking waiting can be avoided, and as a result, moving charging is more convenient than parking filling, so that the thinking is changed, the charging difficulty is solved at ease, and the anxiety is not a problem any more. Considering that the actual daily driving mileage of nearly 80% of automobile users is usually within 80 kilometers, normally, the charging pile can be used for slowly charging and using valley electricity at night when the automobile users do not remotely drive, and a highway network with four directions and eight directions is used when the automobile users remotely travel, so that the problem of remote unlimited cruising is skillfully solved by the aid of a mobile charging and power supply system of a highway network.

The energy density and the quick charging technology of the battery are continuously improved in the future, the mobile charging technology is more beneficial to popularization, if the battery can be fully charged in 5-10 minutes on the premise of not influencing the safety of the battery, the battery capacity of the vehicle does not need to pursue a driving range of 500 kilometers or even more at that time, and perhaps 100-kilometre driving range of 200 kilometers is enough, then the vehicle cost can be greatly reduced, the promotion of the national vehicle with the capacity lower than 10 ten thousand yuan is no longer a dream, the electric vehicle is cheap, convenient and environment-friendly, and the development of the electric vehicle in the blowout is ready to meet the future in a new era.

The China patent application CN201410795407.8 discloses an electric automobile capable of realizing infinite remote cruising and a tracked mobile charging and power supplying system thereof, wherein the charging and power supplying system convenient for the electric automobile to take power is arranged on two sides of a median strip of a highway, the charging and power supplying system is mainly externally connected with a road network power supply from the highway through two wear-resistant conductive slide rails arranged in parallel to realize power supply, the charging and power supplying system is built by virtue of the highway network, and the trackless electric automobile can be operated in a tracked mode, so that the electric automobile can be powered by a power grid for cruising and can be synchronously charged and stored, and the infinite remote cruising of the electric automobile is realized; the scheme for solving some problems is provided through the device, but when unlimited duration electric automobile and highway net are brushed, side brushing is adopted, the requirement on electric automobile and brushing mechanism equipment is higher, the structure is complex, and improvement is needed urgently.
