Description

technical field [0001] The invention relates to an electric vehicle charging station management system. Background technique [0002] With the rapid development of electric vehicles, more and more people have chosen electric vehicles as a means of transportation. However, in the process of using electric vehicles, it often happens that when riding halfway and finding that the battery is insufficient, you can quickly switch to the electric vehicle charger station. charging, and the existing charging station system has the following defects: [0003] (1) The transformer windings of existing electric vehicle charging systems are mostly made of copper wires. This winding structure has the following defects: 1) The skin effect is obvious, which increases energy consumption; 2) The heat dissipation performance of copper wires is not good. 3) Copper wire is easy to oxidize, which will affect its electrical performance; [0004] (2) The charger in the electric vehicle charging sta...

Problems solved by technology

[0003] (1) The transformer windings of existing electric vehicle charging systems are mostly made of copper wires. This winding structure has the following defects: 1) The skin effect is obvious, which increases energy consumption; 2) The heat dissipation performance of copper wires is not good. 3) Copper wire is easy to oxidize, which will affect its electrical performance;

But when the charger is just charging, because the heat is still small, there is no need to consume power to turn on the fan, but now the fan inside the charger is working while the charger is charging, which causes unnecessary consumption of power ;Because the fan is damaged or the air outlet is accidentally blocked, the heat dissipation performance is reduced. At this time, the internal temperature of the charger cannot be cooled in time. When the temperature of the charger exceeds a certain temperature, if the power supply is not cut off in time, the charger will be damaged. damage or even cause an accident;

[0005] (3) After today's charger is plugged in, the indicator light is on, such as red, and when the battery is full, the indicator light turns, such as yellow, to remind people to turn off the power; this charging form has the following defects, when the indicator light changes from After the red color turns to yellow, there is still a certain amount of spare battery capacity. If the power is turned off after the color changes, the battery will be insufficiently charged, and the battery life will be shortened, which will affect the user's use. It needs to be further charged for a period of time after the color is turned off, but it is difficult to grasp how long to charge, and it is impossible for users to check the time frequently. If the charging time is too long, the battery will bulge and affect the battery life. Those defects greatly affect the service life of electric vehicle batteries, and many substances in the batteries are not recyclable, and direct discharge will cause great pollution to the environment, which is not conducive to energy conservation and environmental protection;

[0006] (4) Most of the electric energy used in the existing charging station system is provided by coal power generation. Although this form of power supply still accounts for the main proportion today, with the gradual loss of coal resources and the country's gradual emphasis on low-carbon energy, This form of power supply still needs to be further improved;

[0007] (5) The existing charging station system generally has only one energy storage device. Due to the limitation of the overall size of the charging station system, the energy stored in the energy storage device is limited. When a power failure occurs, the stored electric energy often cannot meet the needs user's charging needs
