Description

Electric vehicle charging system

A charging system, especially a charging system capable of quickly charging an electric vehicle.

With the rise of environmental protection awareness, countries around the world have gradually reduced the use of petrochemical fuels, and have replaced the past use of petrochemical fuels with electricity in order to achieve the goals of energy conservation and carbon reduction and slowing global warming. As a result, the source of power for many vehicles has gradually shifted from oil and gas to electricity. Electric vehicles are a typical example. The current charging methods of electric vehicles can be roughly classified into charging at home and charging stations. Drivers can set up charging adapters at home to charge the electric vehicle using household mains electricity; or they can use the roadside The charging station charges the electric vehicle.

Regardless of whether it is charging at home or at a charging station, the charging system used in homes or charging stations generally uses a slow charging method to continuously charge the battery of an electric vehicle with a small amount of current for a long time, thereby reducing heat generation, but also because of this As a result, the charging rate is slow and cannot be charged quickly. If the car owner is in urgent need of driving an electric car, he may encounter the limitation that the charging rate of the charging system is slow and the electric car cannot be fully charged in a short period of time, resulting in that the car owner cannot drive the electric car in time. This reason in turn affects the convenience of electric vehicles, and is one of the factors that prevent the rapid popularization of electric vehicles. In addition, in order to increase the charging rate of the existing household utility power or charging station, the general practice is that the owner of the car or charging station must apply to the power company to set up a high-voltage system to increase the charging rate by increasing the voltage. However, due to the limitation of the current regulations, only industrial factories can apply for the installation of high-voltage systems, and it is difficult to apply for the installation of high-voltage systems in urban areas or in residential buildings for private use.

In order to increase the charging rate of electric vehicles, the present invention proposes an electric vehicle charging system.
