With the improvement of the living standard of people, the popularity of private cars is higher and higher. The electric automobile driven by electric energy is used as a beauty in the later period, and has the advantages of environmental protection, silence, high speed, money saving and the like. The rapid development of the electric automobile industry not only reduces the consumption of non-renewable energy sources, but also changes the travel mode of people. Meanwhile, a new problem is brought about in that the endurance mileage of the traditional automobile is more than 500km, and the oil filling process is about 5 minutes once. However, the electric automobile needs to reach a cruising mileage of more than 400km, and a process of one full charge needs to reach more than 2 hours, so that the time cost is seriously wasted. To solve this problem, the charging power of the charging pile is designed to be larger and larger, and then the charging voltage and the charging current are also larger and larger, and the maximum charging current reaches even 250A. Therefore, the direct current charging pile with quick charging is continuously pushed out.
When the charging pile is used for rapidly charging the electric automobile, the output large current meets the charging requirement of the electric automobile, but potential safety hazards are buried in a battery system of the automobile, particularly in the charging starting stage or at the time when the charging requirement of the electric automobile is outstanding. Because in the actual output process of charging pile, the response speed of the output current adjustment of the charging module is different, the situation of output current overcharge is easily caused. For example, when the required current of the vehicle battery increases, there is a delay in the output change response of the charging post, resulting in a shock of the output current of the charging post, which is characteristic of the device, and although the shock is short, it also causes some potential troubles, such as damage to the vehicle battery, even charge stop, and the like. Of course, in the actual charging process, the actual output current of the charging pile is higher than the required current of the vehicle battery management system, so that the battery is easily damaged to different degrees, the service life of the vehicle battery is shortened, and more seriously, the vehicle battery fails due to the fact that the vehicle is overcharged, so that the vehicle battery is naturally ignited, property loss is caused, and even personal safety is endangered.
Therefore, to the output of charging of filling electric pile, if make prevention control to the starting current impact of filling electric pile, become a technical problem that fills electric pile research field needs to face.
