[0041] The present disclosure is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present disclosure, but are not intended to limit the present disclosure in any form. It should be noted that, for those of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present disclosure. These all fall within the scope of protection of the present disclosure.

[0042] Figure 1 It is a schematic diagram of the overall architecture of a mobile charging system with separated transport and charging according to an exemplary embodiment. Figure 2 It is a schematic diagram showing the operation of a mobile charging system with separated transport and charging according to an exemplary embodiment.

[0043] like Figure 1 , Figure 2 As shown, the present disclosure provides a mobile charging system with separated transport and charging, including an energy storage module, a transport robot, a power supply and a dispatching center.

[0044] The energy storage module is used to store electrical energy and is also used to power user vehicles and transport robots.

[0045] The transport robot is used to transport the energy storage module to the user's vehicle for charging, and is also used to recover the energy storage module to the power supply and dispatch center. The transport robot and the energy storage module are independent of each other.

[0046] Among them, the carrier robot unloads the energy storage module after transporting the energy storage module to the user's vehicle, and then returns to the power supply and dispatching center to wait for the next task.

[0047] The power supply and dispatching center is used to charge the energy storage modules and to dispatch tasks for the energy storage modules and transport robots.

[0048] Among them, the power supply and dispatching center can respond to the user's charging request and dispatch the carrier robot to transport and recover the energy storage module according to the user's charging request location.

[0049] Through the above technical solution, independent carrier robots and energy storage modules are used to separate the carrier function and the charging function. The carrier robot and the energy storage module can work independently. The carrier robot returns after carrying the energy storage module to the user's charging request location, thereby reducing the number of carrier robots, reducing the idleness of carrier robots, reducing hardware costs, and reducing system space occupancy. It is suitable for charging scenarios with limited charging space; the energy storage module can be used to power user vehicles and carrier robots, saving costs and reducing system complexity; the power supply and scheduling equipment is used to schedule tasks for the energy storage module and the carrier robot, and can optimize resource allocation in real time according to task priority and equipment status, thereby improving resource utilization and system efficiency.

[0050] In a possible embodiment, the power supply and dispatching center includes a substation power supply module, and the substation power supply module is provided with a power management system, the power management system is used to allocate electric energy, and the substation power supply module is used to charge the energy storage module.

[0051] Among them, the power management system of the substation power supply module automatically allocates power and charges the energy storage module according to the power demand of the energy storage module, and optimizes the charging process to avoid overcharging of the energy storage module or battery loss, thereby ensuring the long-term reliability of the energy storage module.

[0052] In a possible embodiment, the power supply and dispatching center also includes a dispatching module for obtaining the transport status information of the transport robot and the status information of the energy storage module, and for performing task dispatching on the transport robot and the energy storage module.

[0053] The transport status information of the transport robot includes the power, mission status, and location information of the transport robot. The status information of the energy storage module includes the location information and storage capacity of the energy storage module.

[0054] As an example, when the storage capacity of an energy storage module in standby state is lower than a preset first threshold, the scheduling module allocates the carrying robot according to the carrying status information of the carrying robot to transport the energy storage module with storage capacity lower than the preset first threshold to the substation power supply module of the power supply and scheduling center for charging.

[0055] Among them, the scheduling module will select a carrier robot whose power level is not lower than the second threshold, whose task status is standby, and which is closest to the energy storage module to transport the energy storage module whose power level is lower than the preset first threshold to the substation power supply module of the power supply and scheduling center for charging.

[0056] As another example, when the power of the carrier robot in the standby state is lower than a preset second threshold, the scheduling module schedules the carrier robot to charge according to the state information of the energy storage module.

[0057] Among them, the scheduling module can dispatch the carrier robot with power lower than the preset second threshold to charge at the energy storage module with power storage capacity not lower than the first threshold and closest to the carrier robot, or dispatch the carrier robot with power lower than the preset second threshold back to the substation power supply module of the power supply and scheduling center for charging, to ensure that the carrier robot has sufficient power to continue to perform the task.

[0058] As another example, when a user's charging request is received, the scheduling module assigns a carrier robot to transport the assigned energy storage module to the user's charging request location to charge the user's vehicle based on the carrier robot's carrying status information and the status information of the energy storage module. The assigned carrier robot unloads the assigned energy storage module and returns to the power supply and scheduling center for standby. After the user's vehicle is charged, the scheduling module reallocates the carrier robot to recover the assigned energy storage module based on the carrier robot's carrying status information.

[0059] Among them, the scheduling module will select a carrier robot with a power level not less than the second threshold and a task status of standby as the assigned robot, and select an energy storage module with a power level not less than the first threshold and a task status of standby as the assigned robot. The assigned carrier robot carries the assigned energy storage module to the user's charging request location to provide charging services. The scheduling module reallocates the carrier robot and still selects a carrier robot with a power level not less than the second threshold and a task status of standby as the reallocated carrier robot.

[0060] When the allocated energy storage module is recovered, the scheduling module will perform subsequent task scheduling according to the storage capacity of the recovered energy storage module.

[0061] If the storage capacity of the recovered energy storage module is lower than a preset first threshold, the reallocated carrier robot carries the recovered energy storage module back to the substation power supply module of the power supply and dispatching center for charging.

[0062] If the storage capacity of the recovered energy storage module is not lower than a preset first threshold, the reallocated transport robot carries the recovered energy storage module back to the substation of the power supply and dispatching center to wait for the next task.

[0063] By separating the transportation function and the charging function, the transport vehicle leaves after transporting the energy storage module to the destination. This can reduce the number of transport robots, reduce system costs, and improve the utilization rate of transport robots. It can also reduce the space occupied by the transport robots when charging. As a result, the energy storage module can operate flexibly in areas with dense parking spaces.

[0064] The dispatch module of the power supply and dispatch center can optimize resource allocation in real time according to task priority and equipment status, thereby improving the overall efficiency of the system.

[0065] In a possible embodiment, the transport robot includes an automatic driving module, which is used to execute scheduling instructions to drive the transport robot to the destination, and is also used to feedback the transport status information of the transport robot to the scheduling module of the power supply and scheduling center.

[0066] Among them, the autonomous driving module realizes positioning, perception, planning, and control functions through data information provided by its own sensors or field sensors, and drives the transport robot to the destination.

[0067] The autonomous driving module is also used to feed back the current position, working status and power information of the transport robot to the scheduling module.

[0068] In a possible embodiment, the transport robot further includes a transport module, the transport module is provided with a lifting mechanism or a traction mechanism, and the transport module is used to carry the energy storage module.

[0069] Among them, the carrier module can realize the transportation of the energy storage module through a lifting mechanism or a traction mechanism, and can also realize the automatic loading and unloading of the energy storage module by using automation technology.

[0070] In a possible embodiment, the energy storage module includes a battery, the battery is provided with a battery management system, the battery is used to store electrical energy, and the battery management system is used to monitor the battery status of the battery in real time.

[0071] Among them, the battery management system can monitor the battery storage capacity, temperature and health status.

[0072] The energy storage module also includes a charging and discharging module, which is used for charging the battery through the substation power supply module of the power supply and dispatching center, and is also used for discharging the battery to the user vehicle or transport robot.

[0073] Among them, the battery of the energy storage module charges the user's vehicle or transport robot through the charging and discharging module.

[0074] The energy storage module can be used to charge user vehicles and transport robots, saving costs and reducing system complexity.
