Description

Technical Field

[0001] This disclosure relates to the field of intelligent connected vehicle technology, and more specifically, to a mobile charging system and method with a separate vehicle and charging system. Background Technology

[0002] As the number of new energy vehicles gradually increases, the disadvantages of fixed charging piles, such as large site occupation and high resource investment, have become apparent. Mobile charging robots, on the other hand, have autonomous mobility, changing the "vehicle-to-pile" charging mode and providing charging services efficiently and flexibly.

[0003] However, current mobile charging robots have tightly coupled transportation and charging functions, requiring each robot to be equipped with an autonomous driving system, which presents challenges such as high cost and complex maintenance. In addition, because mobile charging robots occupy a large space, their operating space is limited in urban areas or parking lots where parking spaces are scarce.

[0004] Therefore, there is an urgent need for a mobile charging system that separates transportation and charging functions to meet the requirements of reducing maintenance costs and space occupation, and to adapt to the development of new energy vehicles. Summary of the Invention

[0008] The energy storage module is used to store electrical energy and also to power the user vehicle and the transport robot.

[0009] The transport robot is used to transport the energy storage module to the user vehicle for charging, and also to retrieve the energy storage module to the power supply and dispatch center. The transport robot and the energy storage module are independent of each other.

[0010] The power supply and dispatch center is used to charge the energy storage module and to schedule tasks for the energy storage module and the transport robot.

[0015] When the battery level of the transport robot in standby mode is lower than a preset second threshold, the scheduling module schedules the transport robot to charge according to the status information of the energy storage module.

[0016] When a user's charging request is received, the scheduling module allocates the transport robot to deliver the allocated energy storage module to the user's charging request location to charge the user's vehicle, based on the transport robot's carrying status information and the energy storage module's status information. After unloading the allocated energy storage module, the allocated transport robot returns to the power supply and scheduling center for standby. After the user's vehicle is fully charged, the scheduling module reallocates the transport robot to retrieve the allocated energy storage module based on the transport robot's carrying status information.

[0017] Optionally, the transport robot includes an autonomous driving module, which is used to execute scheduling instructions to drive the transport robot to its destination, and also to feed back the transport status information of the transport robot to the scheduling module of the power supply and scheduling center.

[0019] Optionally, the energy storage module includes a battery, the battery is equipped 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;

[0020] The energy storage module also includes a charging and discharging module, which is used for the substation power supply module of the power supply and dispatch center to charge the battery, and also for the battery to discharge to the user vehicle or the transport robot.

[0021] According to a second aspect of this disclosure, a mobile charging method with separate carrier and charging facilities is provided, comprising:

[0022] Real-time acquisition of the carrying status information of the transport robot and the status information of the energy storage module;

[0023] In response to a user's charging request, the assigned transport robot and the assigned energy storage module are determined based on the transport status information of the transport robot and the status information of the energy storage module.

[0024] The assigned transport robot is used to transport the assigned energy storage module to the user's charging request location;

[0025] After the assigned transport robot unloads the assigned energy storage module to the user's charging request location, the assigned transport robot returns to the power supply and dispatch center to standby, and the assigned energy storage module charges the user's vehicle.

[0026] After the user vehicle has finished charging, the reassigned transport robot is determined based on the transport robot's transport status information.

[0030] After the user's vehicle has finished charging, if the energy storage capacity of the allocated energy storage module is not lower than the preset first threshold, the reallocated transport robot retrieves the allocated energy storage module from the user's charging request location and places it in standby mode at the scheduling module of the power supply and scheduling center.

[0033] Compared with the prior art, the embodiments disclosed herein have at least one of the following beneficial effects:

[0034] The above technical solution employs independent transport robots and energy storage modules, separating the transport and charging functions. Both the transport robot and the energy storage module can operate independently. The transport robot returns after carrying the energy storage module to the user's charging request location, thereby reducing the number of transport robots, minimizing idle time, lowering hardware costs, and reducing system space requirements. This is suitable for charging scenarios with limited charging space. The energy storage module can power the user's vehicle and transport robot, saving costs and reducing system complexity. The power supply and scheduling equipment is used for task scheduling of the energy storage module and transport robot, and can optimize resource allocation in real time based on task priority and equipment status, improving resource utilization and system efficiency.

[0035] In the embodiments of this disclosure, a transport robot and an energy storage module are allocated based on the transport status information of the transport robot and the status information of the energy storage module. The allocated transport robot then transports the allocated energy storage module to the user's charging request location and returns. This method optimizes resource allocation in real time based on task priority and device status, separates the transport function from the charging function, reduces idle transport robots, thereby reducing the number of transport robots, lowering hardware costs, improving resource utilization, and reducing system space occupation.

[0036] The embodiments of this disclosure use energy storage modules to charge the transport robot, which can save costs and reduce system complexity. Attached Figure Description

[0041] The present disclosure will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present disclosure, but do not limit the present disclosure in any way. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present disclosure. These all fall within the protection scope of the present disclosure.

[0042] Figure 1 This is a schematic diagram of the overall architecture of a carrier-charging separated mobile charging system according to an exemplary embodiment. Figure 2 This is a schematic diagram illustrating the operation of a carrier-charging separated mobile charging system according to an exemplary embodiment.

[0043] like Figure 1 , Figure 2 As shown, this disclosure provides a mobile charging system with separate transport and charging components, including an energy storage module, a transport robot, a power supply and dispatch center.

[0044] Energy storage modules are used to store electrical energy and also to power user vehicles and transport robots.

[0045] The transport robot is used to deliver energy storage modules to user vehicles for charging, and also to retrieve energy storage modules to the power supply and dispatch center. The transport robot and the energy storage module are independent of each other.

[0046] After delivering the energy storage module to the user's vehicle, the transport robot unloads the module and returns to the power supply and dispatch center to standby for the next task.

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

[0048] The power supply and dispatch center can respond to users' charging requests and dispatch transport robots to transport and recover energy storage modules based on the location of the user's charging request.

[0049] The above technical solution employs independent transport robots and energy storage modules, separating the transport and charging functions. Both the transport robot and the energy storage module can operate independently. The transport robot returns after carrying the energy storage module to the user's charging request location, thereby reducing the number of transport robots, minimizing idle time, lowering hardware costs, and reducing system space requirements. This is suitable for charging scenarios with limited charging space. The energy storage module can power the user's vehicle and transport robot, saving costs and reducing system complexity. The power supply and scheduling equipment is used for task scheduling of the energy storage module and transport robot, and can optimize resource allocation in real time based on task priority and equipment status, improving resource utilization and system efficiency.

[0050] In one possible embodiment, the power supply and dispatch center includes a substation power supply module, which is equipped with a power management system for allocating electrical energy and for charging the energy storage module.

[0051] The power management system of the substation power supply module automatically allocates power and charges the energy storage module according to its power demand. It also optimizes the charging process to avoid overcharging or battery damage, thus ensuring the long-term reliability of the energy storage module.

[0052] In one possible embodiment, the power supply and dispatch center further includes a dispatch module for acquiring the transport status information of the transport robot and the status information of the energy storage module, and for scheduling tasks for the transport robot and the energy storage module.

[0053] The transport robot's status information includes its battery level, task status, and location. The energy storage module's status information includes its location and stored capacity.

[0054] As an example, when the energy storage module in standby mode has a power storage capacity lower than a preset first threshold, the scheduling module allocates a transport robot to transport the energy storage module with a power storage capacity lower than the preset first threshold to the substation power supply module of the power supply and scheduling center for charging, based on the transport robot's transport status information.

[0055] The scheduling module will select a transport robot with a power level not lower than the second threshold, a task status of standby, and the closest distance to the energy storage module to transport the energy storage module with a power level 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 battery level of the standby robot is lower than a preset second threshold, the scheduling module schedules the robot to charge based on the status information of the energy storage module.

[0057] The scheduling module can dispatch a robot whose power level is below a preset second threshold to a nearby energy storage module with a power level not below a first threshold for charging, or dispatch a robot whose power level is below the preset second threshold to return to the substation power supply module of the power supply and scheduling center for charging, so as to ensure that the robot has sufficient power to continue to perform its tasks.

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

[0059] The scheduling module selects a transport robot with a battery level not lower than a second threshold and a standby status as the assigned robot, and an energy storage module with a battery level not lower than a first threshold and a standby status as the assigned energy storage module. The assigned transport robot then carries the assigned energy storage module to the user's charging request location to provide charging service. When the scheduling module reassigns transport robots, it again selects robots with a battery level not lower than the second threshold and a standby status as the reassigned transport robots.

[0060] When recovering and distributing energy storage modules, the scheduling module will perform subsequent task scheduling based on the stored capacity of the recovered energy storage modules.

[0061] If the stored energy of the recovered energy storage module is lower than a preset first threshold, the redistributed transport robot will carry the recovered energy storage module back to the substation power supply module of the power supply and dispatch center for charging.

[0062] If the stored energy of the recovered energy storage module is not lower than the preset first threshold, the redistributed transport robot will carry the recovered energy storage module back to the substation of the power supply and dispatch center for standby, waiting for the next task.

[0063] By separating the transportation and charging functions, the transport vehicle can leave after delivering the energy storage module to its destination. This reduces the number of transport robots, lowers system costs, and increases the utilization rate of transport robots. It also reduces the space occupied by transport robots during charging. As a result, the energy storage module can operate flexibly in areas with dense parking spaces.

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

[0065] In one possible embodiment, the transport robot includes an autonomous driving module for executing scheduling instructions to drive the transport robot to its destination, and for feeding back the transport robot's transport status information to the scheduling module of the power supply and scheduling center.

[0066] The autonomous driving module uses data from its own onboard sensors or field sensors to achieve positioning, perception, planning, and control functions, driving the transport robot to its destination.

[0067] The autonomous driving module is also used to provide feedback to the scheduling module on the current location, working status, and battery level of the transport robot.

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

[0069] The transport module can transport the energy storage module through a lifting mechanism or a traction mechanism, and can also use automation technology to achieve automated loading and unloading of the energy storage module.

[0070] In one possible embodiment, the energy storage module includes a battery, which is equipped 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 in real time.

[0071] The battery management system can monitor the battery's energy storage capacity, temperature, and health status.

[0072] The energy storage module also includes a charging and discharging module, which is used by the substation power supply module of the power supply and dispatch center to charge the battery, and also by the battery to discharge to user vehicles or transport robots.

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

[0074] By using energy storage modules to charge user vehicles and transport robots, costs are saved and system complexity is reduced.

[0075] Figure 3 This is a flowchart illustrating a carrier-charging separation mobile charging method according to an exemplary embodiment.

[0076] like Figure 3 As shown, this disclosure also provides a mobile charging method with separate transport and charging, including S11 to S16, in which the power supply and dispatch center is responsible for dispatching the transport robot to carry the energy storage module to provide charging services for the user vehicle, and charging the transport robot and energy storage module after use. It can be applied to the mobile charging system with separate transport and charging provided above in this disclosure.

[0077] S11 acquires real-time information on the carrying status of the robot and the status of the energy storage module.

[0078] Among these features, the system acquires real-time information on the carrying status of the robot and the status of the energy storage module to prepare for responding to users' charging requests.

[0079] S12, in response to the user's charging request, determines the assigned transport robot and the assigned energy storage module based on the transport robot's carrying status information and the energy storage module's status information.

[0080] The assigned transport robot is a transport robot with a power level not lower than the second threshold and a standby state in the task status, and the assigned energy storage module is an energy storage module with a power storage capacity not lower than the first threshold and a standby state in the task status.

[0081] Steps S11 to S12 are applied to the scheduling module of the power supply and dispatch center, which is also used to receive users' charging requests.

[0082] S13, the assigned transport robot transports the assigned energy storage module to the user's charging request location.

[0083] The assigned transport robot uses its onboard autonomous driving module and transport module to go to the power supply and dispatch center to obtain the assigned energy storage module, and then transports the energy storage module to the user's charging request location.

[0084] S14, after the assigned transport robot unloads the assigned energy storage module to the user's charging request location, the assigned transport robot returns to the power supply and dispatch center to standby, and the assigned energy storage module charges the user's vehicle.

[0085] S15: After the user's vehicle has finished charging, determine the reassigned transport robot based on the transport robot's transport status information.

[0086] Among them, the reassigned transport robot is the transport robot whose power is not lower than the second threshold, whose task status is idle, and whose distance from the assigned energy storage module is the closest.

[0087] Step S15 is applied to the scheduling module of the power supply and dispatch center.

[0088] S16 employs a redistributed transport robot to retrieve the allocated energy storage modules from the user's charging request location and transport them to the power supply and dispatch center.

[0089] The above technical solution allocates a transport robot and an energy storage module based on the transport status information of the transport robot and the status information of the energy storage module. The allocated transport robot then transports the allocated energy storage module to the user's charging request location and returns. This allows for real-time optimization of resource allocation based on task priority and equipment status, separating the transport function from the charging function, reducing idle transport robots, thereby reducing the number of transport robots, lowering hardware costs, improving resource utilization, and reducing system space occupation.

[0090] In one possible embodiment, S16, employing a redistributed transport robot to retrieve the allocated energy storage module from the user's charging request location to the power supply and dispatch center, may include S161 to S162.

[0091] S161, after the user's vehicle has finished charging, if the energy storage capacity of the allocated energy storage module is lower than a preset first threshold, the reassigned transport robot will retrieve the allocated energy storage module from the user's charging request location and charge it at the substation power supply module of the power supply and dispatch center.

[0092] Once the energy storage module is fully charged, it can be transported by a robot to the scheduling module to standby and await the next task.

[0093] S162, after the user's vehicle has finished charging, if the energy storage capacity of the allocated energy storage module is not lower than the preset first threshold, the redistributed transport robot retrieves the allocated energy storage module from the user's charging request location and puts it into standby mode at the power supply and dispatch center's dispatch module.

[0094] In one possible embodiment, a mobile charging method with separate carrier and charging stages further includes S17.

[0095] S17. If the battery level of the transport robot is lower than the preset second threshold, the transport robot is scheduled to charge according to the status information of the energy storage module.

[0096] Specifically, the system can dispatch a robot whose power level is below a preset second threshold to a nearby energy storage module with a power level not lower than a first threshold for charging, or dispatch a robot whose power level is below the preset second threshold to return to the substation power supply module of the power supply and dispatch center for charging, ensuring that the robot has sufficient power to continue performing its tasks.

[0097] Step S17 can be applied to the scheduling module of the power supply and dispatch center.

[0098] The embodiments of this disclosure use energy storage modules to charge the transport robot, which can save costs and reduce system complexity.

[0099] In this disclosure, according to steps S11 to S17, whenever a user requests charging, execution begins from step S12.

[0100] The specific embodiments of this disclosure have been described above. It should be understood that this disclosure is not limited to the specific embodiments described above, and those skilled in the art can make various modifications or variations within the scope of the claims, which do not affect the substantive content of this disclosure. The above-described preferred features can be used in any combination without conflict.
