BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automatic battery exchange system for an electric vehicle, and more particularly, to an automatic battery exchange system for an electric vehicle that can perform a battery replacement operation for an electric vehicle more stably and improve safety and durability .

Generally, fossil fuels such as petroleum such as gasoline, light oil, natural gas such as LPG and LNG are mainly used as fuels, but fossil fuels are depleted with time as resources are limited, and their prices are continuously rising It is in the present situation.

In addition, fossil fuels not only exhaust a variety of exhaust gases that pollute the atmospheric environment during their use, but also discharge a large amount of carbon dioxide, which is a major cause of global warming, Electric vehicles were developed.

Electric vehicles include a battery powered electric vehicle, a hybrid electric vehicle using a motor and an engine together, and a fuel cell electric vehicle. In addition, in order to expand the activation and diffusion of electric vehicles, it is essential to construct a charging infrastructure that can be easily charged anytime and anywhere.

However, unlike automobiles that use petroleum (gasoline, light oil, etc.) or electric vehicles, electric vehicles are charged by the plug-in method, unlike automobiles that use natural gas. Consumers are very inconvenient because of long waiting time. There is no economical efficiency due to excessive waiting time.

In order to solve the above problems, as disclosed in Korean Patent Laid-Open Publication No. 10-2011-0078289, the battery of the electric vehicle is charged in advance without directly charging the battery, (Hereinafter, referred to as " battery replacement system ").

However, there is a drawback that the application of such a system has inherent risks such as falling of the battery.

Particularly, electric automobile batteries such as electric buses have a large capacity and load and volume, which are difficult to transfer and replace, and cause serious safety accidents in case of a fall. Therefore, stability, safety and durability are verified The development of a new system is urgently required.
