Description

  According to the present invention, an electric vehicle (EV) is equipped with a generator dedicated for charging so that it can be charged while traveling, minimizing battery consumption, reducing the chance of external charging, and extending the travel distance. It is a thing.

  Conventionally, an electric vehicle (EV) has a short mileage, requires time and effort to charge a battery, and in terms of performance, such as a gasoline vehicle, a hybrid vehicle (HEV), a fuel cell vehicle (FCV), a hydrogen engine vehicle, etc. For the wrong reason of being inferior, wrong views of industry, some politicians, government agencies, etc. have been made. Fuel cell vehicles (FCVs), hydrogen engine vehicles, etc. are not on the market as soon as possible due to resources such as hydrogen and platinum, production costs, and the like. The current situation is waiting for cars to improve air pollution in the industry and the general public. The present invention of an electric vehicle (EV) is an ideal vehicle that contributes completely to environmental protection without pollution.

  In an electric vehicle (EV), it was decided to solve the problem whether the battery consumption was reduced without being worried about the mileage and the battery could not be charged by itself.

  Aside from the traveling motor, a charging-only generator was installed so that charging could be done while traveling, so that the problem was solved.

In this way, by attaching a power generation device dedicated to charging to an electric vehicle (EV), battery consumption due to the driving motor can be charged during traveling regardless of the distance traveled, so there are concerns about long-term driving In addition, since the travel expenses can be self-sufficient, a single charge is only about 100 yen, and it can be driven all day. It also shortens the charging time, making it an ideal electric vehicle (EV). In addition, since the battery can be charged while traveling, the capacity of the battery can be reduced. Therefore, the weight and volume of the battery can be reduced, and an ordinary lead battery is sufficient. Electric vehicles (EVs) will certainly contribute to global weather changes, improvement of global warming and environmental lifestyle habits.

The present invention is a schematic plan view of an electric vehicle (EV) 1. Motors 4 and 5 which are power sources of the car are incorporated in the wheel wheels of the rear wheels 2 and 3. Since the motors 4 and 5 directly rotate the wheels 2 and 3, the axle 10 is fixed to the vehicle body. The generators 6 and 7 for charging are passed through the axle 10 like the motors 4 and 5, and the motor 4 and the generator 6, and the motor 5 and the generator 7 are fixed so as to be the same rotor. When the battery 9 is connected to the motors 4 and 5, when the accelerator is depressed through the controller 8 that adjusts the current and the like, the current flow changes, and the motors 4 and 5 rotate to drive the wheels 2 and 3. The generators 6 and 7 that rotate at the same time start generating electricity according to the rotation, and charge the battery 9 through the IC controller 12 at all times during operation. When the brake is stepped on, the current flow stops and the EV-specific brake, which is a regenerative brake, works. The motors 4 and 5 and the generators 6 and 7 are structurally the same. If a current is passed, it becomes a motor, and if a rotor is rotated without passing a current, it becomes a generator. The present invention makes good use of this characteristic. In this way, with direct and drive EV vehicles, when charging is possible while always running with a charging dedicated generator, the mileage will be extended as an EV vehicle, and high performance and expensive lithium batteries, nickel, Even without using a cadmium battery or the like, a lead battery can be sufficiently useful.

When the electric vehicle (EV) of the present invention is manufactured and sold, it is possible to prevent the occurrence of air pollution, which is the cause of global warming, and thus contributes to the improvement of the environment.
The topic of fuel cell vehicles (FCVs), which are currently being talked about, is a major problem with the supply of hydrogen. The hybrid vehicle (HEV) does not contribute much to the environment because it uses half gasoline, and the disadvantage is that the vehicle is expensive. We do not know when a hydrogen engine vehicle will be completed, and there is no infrastructure for hydrogen-based vehicles such as fuel cell vehicles (FCV) and hydrogen engine vehicles.
From such a current situation, the future of the electric vehicle (EV) of the present invention will be a star of the automobile society, contributing to the social life environment and thus contributing to the development of the industrial economy.
