Description

technical field [0001] The invention relates to a composite energy charging energy storage system and a method thereof. Background technique [0002] Electric vehicles are powered by vehicle-mounted power supplies and drive wheels with motors, which have the advantages of energy saving and environmental protection. With the low-carbon economy becoming the main theme of my country's economic development, electric vehicles, as an important part of the new energy strategy and smart grid, and one of the strategic emerging industries determined by the State Council, will surely become the focus of the development of China's automobile industry and energy industry in the future . However, the electric vehicle industry is a systematic project, and the electric vehicle charging station is one of the main links. The electric vehicle charging station refers to the station for charging electric vehicles. Coordinated development. At present, most of the electric vehicle charging stati...

Problems solved by technology

At present, most of the electric vehicle charging stations existing or under construction in China use the method of directly charging the battery by the State Grid. For example, during the peak power consumption during the day, a large number of electric vehicles need to be charged, which will affect the power grid Power supply, once the power grid fails, it will not be able to continue to meet the electric vehicle charging and swapping services

In addition, the fast charging of electric vehicles requires instantaneous and powerful power, which cannot be met by conventional power grids. It is necessary to build a dedicated charging network, which involves the transformation of the entire national power grid. The major transformation of the national power grid is not a trivial matter and costs a lot of money.
