Description

Electric vehicle charging device

The present invention relates to an electric vehicle charging apparatus for charging a battery of an electric vehicle driven by electric energy charged in a battery, and more particularly, along a charging vehicle driving path installed at an upper or basement of a pier built on the ground. An electric power source that supplies external power to frequently-charged cars, and electrically connects the car and the electric car so that the electric car can be charged while driving, thereby establishing a charging infrastructure that does not waste time due to charging. It is to provide a charging device for automobiles.

Recently, in order to cope with the strengthening of CO2 emission regulations, fossil fuel depletion and high oil prices due to environmental problems such as global warming, we are trying to increase the development of eco-friendly cars and the spread of green cars.

Environmental changes such as the regulation of CO2 emissions require not only the creation of a new market but also a change from the real world to a completely different dimension. To this end, countries are fiercely competing to preempt the market by investing a lot of capital and technology. The transportation sector, which accounts for a large portion of CO2 emissions, is calling for a change from the existing internal combustion engine cars to the environment-free and low-polluting vehicles.

Automobile companies around the world are in a hurry to develop electric vehicles, which has emerged as a powerful alternative because the development of low- and low-pollution automobiles is directly linked to the company's survival problems.

In order to develop and commercialize electric vehicles, the construction of charging infrastructure should be preceded. The establishment of charging infrastructure is becoming an essential element for the dissemination and activation of electric vehicles. Gains and market dominance are expected.

Green cars that are being supplied to date are hybrid cars, plug-in hybrid cars, fuel cell cars, electric cars, and clean diesel cars.

Hybrid cars are cars that use two or more kinds of power sources together. Usually refers to a car using a gasoline (or diesel) engine and an electric motor together. As soon as fuel is consumed, running electric motors instead of gasoline engines reduces fuel use and reduces emissions. The electrical energy required to operate the electric motor is obtained from the driving force of the engine 100%.

Plug-in hybrid car A hybrid car that can be used to charge household electricity on a battery. If you do not run more than 50 ~ 60km per day, it is possible to drive only with charged electricity, and research and development for commercialization is being made by manufacturers.

Fuel cell vehicles, like electric vehicles, operate with the power of a 100% electric motor, but are distinguished from conventional vehicles in that they obtain electrical energy from fuel cells.

A fuel cell is a device that generates electrical energy by reacting hydrogen and oxygen. Hydrogen is stored in the car, which generates electricity whenever needed, and the energy is used to drive the car. There is no exhaust, only water.

However, it is likely to require considerable development period until practical use. Mass production of hydrogen and the hydrogen storage method in the vehicle remain obstacles.

An electric vehicle is a vehicle that does not have an engine and runs only by an electric motor. The necessary electricity is obtained through 100% charging.

No air pollution and little noise. To drive long distances and speed up, the amount of electricity stored in the battery must be very large. The current technology is limited to traveling at a distance of about 200 to 300 km.

If electric charging facilities are expanded in the future and the electricity supply is renewable energy such as wind or solar power, it can be regarded as a green car.

Clean diesel cars are now being developed by the world's automakers as an advanced medium-term alternative to carbon dioxide regulations.

These technologies are known to reduce CO2 emissions by about 20-30%, and are less expensive than hybrids or fuel cells.

It has a strategic ripple effect and is considered as an important technology element for securing medium-term competitiveness. For example, at the 2008 Paris Motor Show, Renault-Nissan Motor Co. introduced a new hybrid car, which is also known for its high-efficiency diesel engine.

Meanwhile, batteries used in conventional electric vehicles are expensive and have a long charging time due to short battery life.

To solve this problem, technologies for charging while driving are being disclosed, and the rigid body wires that supply electricity are installed like cobwebs along the lanes on the roads to install pentagraphs (trolleys), which are separate contact mechanisms, in electric vehicles. In addition, the aesthetics of the car are not good, and the plug input charging method of the existing electric vehicle is different, and the current flow of electric current, electromagnetic waves, and wires for electric supply work are not commercialized due to many problems.

In addition, when the current electric vehicle is not in operation, the charger is unplugged after entering the residential area or charging station, and the charger is plugged into an outlet provided in the electric vehicle. It is applied to small-sized, light-weight electric vehicles first, so that to prevent the increase of global air pollution, it is a way to quickly convert all cars into electric lights.

To this end, it is important to build a charging infrastructure, but it is possible to eliminate the shortcomings of the electricity supply and wire system of the conventional electric vehicles and make use of the advantages, and install the system that can be charged while driving in the inner and outer ring roads or the basement and ground side of the highway. Electric vehicle supply will be activated only when the charger is charged and when charging.

Conventional charging while driving prior art, 'Electric vehicle driving system for charging while driving', Korean Patent Publication (A) 10-2011-0065684 (2011.06.16.), Republic of Korea Patent Publication (A) 10-2010- The electric vehicle of 0012562 (2010.02.08.) And the trolley electric vehicle of Unexamined-Japanese-Patent No. 10-2009-0101429 (2009.09.28) are mentioned.

However, these prior art has to use a roadside pole to install a supply wire in the air driveway to install a large and heavy pentagraph (trolley) device in the electric vehicle, which has the problem of replacing the plug-in charging method of the current electric vehicle and harms the city view.
