Description

[0001] POWER GENERATION AND DISTRIBUTION SYSTEM FOR VEHICLE [0002]

The present invention relates to a power generation and power distribution system, and more particularly, to an intelligent battery unit capable of generating electricity using at least one wind turbine and a solar module, efficiently storing and controlling the same, To a power generation and power distribution system for a moving vehicle that allows the driver to use the power produced at the right place.

A vehicle is a vehicle that can travel on land using a means such as a wheel, a car, a train, a truck, as well as an airplane and a ship. .

Most of the moving means, which can be defined as described above, does not need to produce electric power itself. Most of the moving means, such as an automobile, a truck, an aircraft and a ship, use electric energy In most cases, the engine is powered by an external power supply means and does not produce electricity by itself. Of course, such moving means may require electrical energy, but this is for driving auxiliary equipment, which is generally solved by using a large capacity rechargeable electric battery.

However, there is a case in which a larger amount of electric power is required than the above-mentioned general moving means. In particular, when it is necessary to maintain the temperature inside the trailer at a specific temperature among the cargo trailers, Or when a warming-up operation is required, a large power is required. Conventionally, a separate battery is installed in a trailer to operate a refrigerator or a heater (hereinafter referred to as a refrigerator) in the cargo trailer. However, when the trailer is transported in a short period of time, A problem may occur due to discharge and exhaustion of the battery.

Also, when the trailer is to be transported for a long period of time as described above, it is necessary to use a larger capacity battery in order to operate the refrigerator in the trailer for a long time. When the large capacity battery is installed inside the trailer, There is a disadvantage in that the room to be loaded is reduced and the cost of logistics is increased. Therefore, in order to operate the trail which requires a large amount of electric current for a long period of time, it is necessary to provide a system capable of generating power on its own while operating.

As described above, a regenerative power generator is applied to the moving means, and a regeneration utility model No. 20-0429107 (hereinafter referred to as Prior Art 1) discloses a cooling and heating device for a truck. Prior art 1 described above is a technology for providing electric power used for cooling and heating the inside of a lorry using wind power and solar light as a cooling and heating device for a lorry.

Although the prior art 1 has a somewhat similar aspect to the present invention in terms of using a wind power and a solar power generator to install a power generation system in a vehicle, the present invention relates to a cooling and heating apparatus inside a trailer The prior art 1 differs from the present invention in that it produces electricity for cooling and cooling the driver's seat of a vans, and thus the prior art 1 provides a display for the user to control the produced electric power The structure is also somewhat different from the present invention, and it is judged that the present invention can easily obtain the inventive step from the prior art 1.

As a prior art related to a wind turbine generator which can be installed in a vehicle or the like, there are disclosed in Patent Publication Nos. 10-2011-0049646, 10-2011-0046041, and Registration Utility Model No. 0-0429157, It is judged that the configuration, the operation method, and the purpose are all different.
