The invention relates to the technical field of electric vehicle charging, in particular to a control method for an electric vehicle charging system based on new energy applications. If the power of electric energy provided by the new energy power supply system is less than the output power of the electric vehicle charging pile, the energy distribution management module starts the energy storage system to supply power to the electric vehicle charging pile, and at the same time monitors the remaining capacity of the energy storage battery inside the energy storage system , when the set capacity ratio is reached, the energy distribution management module sends a signal to start the diesel power supply system to provide electric energy until the mains power returns to normal or the power of electric energy provided by the new energy power supply system is not less than the output power of the electric vehicle charging pile, then the diesel is turned off Power supply system and energy storage system, and charge the energy storage system. It can balance the electricity pressure brought by the newly added power load installation capacity of the electric vehicle charging station, and establish a safe, reliable, noise-free and pollution-free intelligent charging system for electric vehicles.
Description
technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a control method for an electric vehicle charging system based on new energy applications. Background technique [0002] With the increasingly severe environment, the proportion of new energy vehicles is gradually increasing, and urban transportation is dominated by electric vehicles, which will become the future development direction and provide a strong guarantee for energy conservation and emission reduction. But whether it is a hybrid vehicle or a pure electric vehicle, it needs to be charged by an external power supply and needs a charging facility. The traditional electric vehicle charging stations are powered by the municipal power grid. As we all know, thermal power generation has caused great pollution to the environment. In addition, due to the single source of municipal power supply, once the mains power fails or fails, the electric vehicle charging ...
