Problems solved by technology
At present, the charging project of charging piles is not perfect enough. Because all the environments faced by charging piles are quite complicated, such as EMC environment, overvoltage and undervoltage environment, overcurrent and undercurrent environment, etc., before the charging pile is officially put into the market, It is often necessary to test the charging characteristics of the charging pile in the laboratory, which requires a simulation device and method suitable for the working characteristics of the charging pile

A device and method for simulating the working characteristics of a charging pile, which is provided with a virtual load power source and a simulation control system; the virtual load power source is provided with a voltage source and a current source, and the positive pole of the voltage source is connected to the power supply interface of the charging pile The voltage terminal of the voltage source is connected to the voltage terminal of the charging interface of the charging pile; the positive pole of the current source is connected to the current terminal of the power supply interface of the charging pile, and the negative pole of the current source is connected to the charging terminal of the charging pile. The current terminal of the interface is connected; the analog control system controls the output characteristics of the virtual load power source through the characteristics of the output current of the charging pile, and completely simulates the real working state of the charging pile in the actual charging process. The invention provides a convenient way for laboratories to conduct various tests of charging piles.
Description
【Technical field】 [0001] The invention relates to a charging pile, in particular to a simulation device and method for the working characteristics of the charging pile. 【Background technique】 [0002] In response to the increasingly scarce oil situation, various countries have successively introduced a number of policies to promote the development of electric vehicles, and various electric vehicles have also sprung up one after another. However, the use and promotion of electric vehicles is not just as simple as producing electric vehicles and selling them to consumers. The development of electric vehicles is a huge system engineering, including the production of electric vehicles, maintenance of complete vehicles and accessories, supporting charging projects, In terms of battery recycling, user training, component standardization sequence, etc., the supporting charging project is an indispensable support system, similar to the gas station of traditional gasoline vehicles, i...
