Description

Technical Field

[0001] The present invention relates to the technical field of charging stack energy scheduling, and in particular to a method for scheduling charging stack energy and output topology relationship based on a three-dimensional matrix structure. Background Art

[0002] A charging pile is a charging station where multiple charging guns share a charging module through a switch. Usually, the charging gun and the charging module are installed separately, so it is also called a split charging pile. In the charging pile system, the three-dimensional matrix structure is a complex but efficient energy scheduling architecture. It adds a new dimension on the basis of the traditional two-dimensional (power module and charging terminal) to manage the distribution and flow of energy more flexibly and accurately.

[0003] The energy scheduling and output topologies of charging piles currently in use mainly adopt full matrix topology and ring topology. The full matrix topology means that any charging gun can call any charging module for charging through the corresponding switch component. In actual use, the full matrix topology has high allocation flexibility, but it has problems such as a large number of nodes, high manufacturing cost, and large footprint. The ring topology means that the charging module and charging gun (charging terminal) are regarded as nodes, and the energy transmission channel between them is regarded as a link. These nodes are connected end to end through the link to form a closed ring structure. Compared with the full matrix topology, the ring topology is less flexible because the energy transmission path is restricted by the ring structure and cannot achieve direct connection between any nodes like the full matrix topology.

[0004] The existing technology has the following technical pain points in practical applications: the existing ring topology has poor flexibility, the energy transmission path is limited by the ring structure, and direct connection between any nodes cannot be achieved, resulting in poor flexibility in charging energy power distribution. Therefore, the present invention provides a method for scheduling the relationship between charging stack energy and output topology based on a three-dimensional matrix structure. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a method for scheduling the relationship between the energy and output topology of the charging stack based on a three-dimensional matrix structure, so as to solve the problem that the flexibility of the existing ring topology structure is poor and the energy transmission path is restricted by the ring structure, and direct connection between any nodes cannot be achieved, resulting in poor flexibility in the energy and power distribution of the charging stack.

[0013] A position sensor is installed on the guide rail, and the position sensor is used to collect the real-time position of the moving element on the guide rail.
