Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] First Embodiment

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 , wherein, Figure 1 is a structural schematic diagram of a first embodiment of a charging system based on distributed mobile energy storage provided by the application; Figure 2 is a structural schematic diagram of a state module shown in Figure 1 ; Figure 3 is a structural schematic diagram of a storage control module shown in Figure 1 . A charging system based on distributed mobile energy storage, comprising: a control module, a state module and a scheduling module;

[0033] The control module is used to control the state module and the scheduling module to work;

[0034] The state module is used to detect and analyze the charging pile, the power grid power supply state and the mobile energy storage package state;

[0035] The scheduling module is used to schedule the mobile energy storage package to a suitable area;

[0036] The state module comprises an analysis module, a detection module, a charging module, a power grid power supply module, a battery management module, a mobile power supply module and a storage control module, the analysis module is bidirectionally connected with the detection module, the input ends of the charging module, the mobile power supply module and the power grid module are connected with the output end of the detection module, the battery management module is bidirectionally connected with the mobile power supply module, and the input end of the storage control module is connected with the output end of the mobile power supply module.

[0037] When the power grid peak value and the charging module peak value are detected by the data acquisition module, when the power grid peak value is high, the mobile energy storage package stored in the battery management module is transported to the charging module in the area with high peak value through the mobile power supply module, connected with the storage control module, and the charging module is powered, thereby reducing the risk of charging peak value period to the power grid impact load.

[0038] When the peak value of a certain area in the charging module is high at that time, the storage battery can be transported to the area with high peak value for power supply through the mobile power supply module, thereby preventing the risk of high charging peak value to the power grid impact load.

[0039] The mobile energy storage package is a battery, the mobile power supply module moves the mobile energy storage package to the connection of the storage control module through the AGV, and the mobile energy storage package and the storage control module are connected through the lifting mechanism of the AGV.

[0040] Based on the "energy space-time transfer" flexible energy supply system of distributed mobile energy storage and AGV automatic handling, a "dynamic energy storage resource pool + intelligent" distributed energy supply architecture is constructed, which solves the problem that the traditional charging station relies on the fixed power grid interface and faces the risk of high expansion cost and load impact. Although fixed energy storage can buffer, it lacks cross-regional scheduling capability.

[0041] By standardizing the mobile energy storage package, charging is concentrated in the valley period or in the area with surplus grid capacity to form a distributed energy storage resource pool. Combined with the intelligent scheduling system of the unmanned AGV cluster, the system is based on a three-layer decision architecture (central control module + scheduling module + state module), calculates the comprehensive cost of the energy storage package through a dynamic resource matching engine, realizes path optimization through a multi-AGV collaborative strategy, and guarantees precise power supply for fast / slow charging interfaces through power self-adaptive technology. Finally, a "demand-resource-execution" closed-loop scheduling system is constructed.

[0042] The scheduling module is an edge AGV controller that schedules the AGV automatic guided vehicle, transports the mobile energy storage package in the battery management module, and transports the mobile energy storage package that needs to be charged into the battery management module for charging.

[0043] The system realizes efficient charging of electric vehicles through energy space-time scheduling and dynamic power enhancement. In the first stage (energy storage supply), the standardized mobile energy storage package is charged in the valley period of the grid (or in the area with surplus capacity). The central control module (EMS) optimizes the charging strategy based on the electricity price signal and the grid state. The essence of EMS optimization is "dynamic decision-making under multiple constraints": taking grid safety as the boundary, taking the electricity price signal as the economic guide, and taking demand prediction as the basis for scheduling. Through dynamic allocation of mobile energy storage resources, the core goals of peak load shifting, reducing electricity costs, and improving system revenue are achieved. In the second stage (demand response and scheduling), when the user initiates a charging request, EMS collects demand and resource data in real time through the hardware layer BMS; generates scheduling instructions based on dynamic algorithms; relies on high-response hardware to ensure execution stability; and finally realizes "demand triggering → analysis → scheduling → power supply" in seconds. Real-time analysis of demand type (fast / slow charging), battery pack location, and state of charge, scheduling of unmanned AGV to accurately transport full-energy storage packages from the warehouse to the target charging pile. AGV completes the automatic docking and locking of the energy storage package and the charging pile connector.

[0044] In another embodiment, without the grid power supply module, the analysis module analyzes the charging demand of the charging module collected by the inspection module (such as fast charging, slow charging, and super-large current fast charging). The scheduling module selects the mobile energy storage package with the appropriate discharge power in the battery management module according to the needs of the charging module for fast charging, slow charging, and super-large current fast charging, and transports it to the charging module area. Connect with the storage control module to supply power to the charging module.

[0045] Therefore, the mobile energy storage package with appropriate discharging power can be flexibly adjusted according to the charging demand of the charging module, and the charging module is powered at an appropriate position, so that the risk of impact load of the power grid is reduced, the problems of power fluctuation and interface compatibility existing in direct power supply of the mobile energy storage package are solved, and the output characteristics of the battery package are used for traditional energy storage charging, and the AC slow charging demand is compatible.

[0046] Please refer to Figure 2 The detection module includes a data acquisition module, a fault detection module and a voltage monitoring module, and the voltage monitoring module includes a power grid detection module, a charging monitoring module and a battery monitoring module.

[0047] The data acquisition module acquires the values of the current sensor (such as a Hall current sensor, a Rogowski coil, a shunt) or the voltage sensor (such as a capacitor voltage divider type voltage sensor, an electromagnetic voltage transformer, a Hall voltage sensor) for detecting the peak value of the power grid and the peak value of the charging module, and simultaneously acquires the power and position data of the storage motor on the mobile power supply module.

[0048] Meanwhile, the fault detection module can detect the charging value of the charging module, so that the repair can be timely when the charging module is damaged or abnormal.

[0049] Please refer to Figure 2 The analysis module includes a charging peak value and a peak period, the charging peak value refers to the value of the impact load of the power grid, and the peak period refers to a period when the charging capacity needs to be large.

[0057] The mobile energy storage bag is internally fixedly connected with connectors matched with the two DC connectors 12, so that the mobile energy storage bag can supply power to the charging module after the connectors are connected with the two DC connectors 12.

[0058] The controller 11 is connected with the charging pile, and when the mobile energy storage bag is present, the charging pile is supplied with power, and when the mobile energy storage bag is absent, the charging pile is supplied with power through the power grid, so that the power grid and the mobile energy storage bag are switched.

[0060] In use, the state of the charging module is detected by the detection module, and the detected data is analyzed by the analysis module, so that the charging state of different charging areas is judged, and whether the charging peak is reached is judged.

[0061] When the charging peak is reached, the mobile power supply module is controlled by the scheduling module to move to the required area and connect with the storage control module to supply power to the charging module.
