Abstract

The invention provides a charging pile efficiency optimization module scheduling method. A charging pile comprises at least one charging gun. The method comprises the steps of receiving a charging request from a device to be charged, wherein the charging request comprises needed voltage Un and needed current In of the device to be charged; and obtaining electric energy output efficiency information of at least one power module, determining the charging scheme under the current charging request based on the charging request of the device to be charged and electric energy output efficiency information of at least one power module, judging whether the currently idle power module can sufficiently execute the charging scheme or not, responding to the fact that the currently idle power module can sufficiently execute the charging scheme, and controlling at least one charging gun to output electric energy of the corresponding power module according to the charging scheme. Electric energy ofeach power module is sufficiently and reasonably used, and the problems that a power module is not reasonable in uniform distribution, large in module power loss, and low in work efficiency can be solved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging piles, and in particular relates to a method for optimal module scheduling of charging pile efficiency. Background technique [0002] Under the background of the current shortage of oil resources in the world, increasing environmental pollution and global warming, vigorously promoting and developing energy-saving-environmental-low carbon new energy vehicles is the direction and goal of human society to pursue the sustainable development of the automotive industry. Therefore, electric vehicles Large-scale development has become an inevitable trend. However, with the large-scale development of electric vehicles and the sharp increase in the amount of charging, the power loss during the charging process has become a non-negligible part. According to statistics, the average charging loss of the DC charging pile station accounts for about 10% of the total charging capacity. According...
