Description

Technical Field

[0001] The present application relates to the field of power supply equipment, and in particular to a mobile energy storage and charging system. Background Art

[0002] The rise of charging pile technology is primarily driven by the rapid development of new energy vehicles. With the global energy crisis and growing environmental awareness, new energy vehicles are rapidly becoming a new market favorite as a key way to reduce greenhouse gas emissions and achieve green mobility. As the primary representative of new energy vehicles, electric vehicles are becoming increasingly popular, and with them, the demand for charging facilities is also increasing. Charging piles, serving as "energy refueling stations" for electric vehicles, are crucial for driving the widespread adoption of new energy vehicles.

[0003] Traditional charging piles are typically installed in fixed locations such as parking lots, gas stations, or residential communities. However, their limitations become apparent in special circumstances, such as sudden power outages, natural disasters, and remote locations. This limitation primarily stems from their relatively weak energy storage capacity, relying primarily on grid power for charging. In the event of a grid outage or failure, traditional charging piles will not function properly.

[0004] Based on this, there is an urgent need for a mobile energy storage and charging system to solve the problems existing in the above-mentioned prior art. Utility Model Content

The mobile energy storage charging vehicles include a control device, a battery module, an AC input module, a DC contactor, and a DC conversion module.

[0009] The beneficial effect of this technical solution is that the individual mobile energy storage charging vehicles in the mobile energy storage charging system are not restricted by the geographical location of fixed charging stations and can be moved to different locations as needed to provide charging services for electric vehicles and other electrical equipment. In the event of natural disasters, power outages or other emergencies, mobile energy storage charging vehicles can be quickly deployed to the affected areas to provide necessary charging services for electrical equipment. Since mobile energy storage charging vehicles can be flexibly deployed, the need to build fixed charging stations in remote areas or temporary demand locations is reduced, thereby reducing infrastructure investment costs. Mobile energy storage charging vehicles can charge when the grid load is low and provide power support during peak hours, which helps balance the grid load and enhance the stability of the grid.

[0010] In summary, the mobile energy storage charging system provides a flexible charging solution that can meet the charging needs of power-consuming devices in different scenarios. For example, it can be quickly deployed to areas affected by power outages to provide emergency power support for critical facilities and electric vehicles. After a natural disaster, even if the traditional power grid is damaged, the individual mobile energy storage charging vehicles in the mobile energy storage charging system can serve as an independent power source, providing temporary charging services to the disaster area and supporting the operation of rescue vehicles and equipment. Through cascade charging, the charging and discharging strategies of the battery modules of each mobile energy storage charging vehicle can be flexibly adjusted according to actual needs.

[0012] This technical solution benefits from integrating the input circuit breaker, AC contactor, and AC / DC converter into a single module, simplifying system design and installation and facilitating maintenance and upgrades. Furthermore, it can draw AC power from a variety of AC power sources (such as the grid and generators), increasing the system's applicability and flexibility.

[0027] The present application is further described below with reference to the accompanying drawings and examples.

[0028] Figure 1 This is a system block diagram of a mobile energy storage and charging system proposed in this application.

[0029] Figure 2 This is a schematic diagram of the framework structure of a mobile energy storage charging vehicle proposed in this application. DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0031] Reference Figure 1 and Figure 2 , Figure 1 This is a system block diagram of a mobile energy storage and charging system proposed in this application. Figure 2 This is a schematic diagram of the framework structure of a mobile energy storage charging vehicle proposed in this application.

[0032] The embodiment of the present application provides a mobile energy storage charging system, which includes multiple mobile energy storage charging vehicles, each of which includes a control device, a battery module, an AC input module, a DC contactor, and a DC conversion module. The battery modules of each mobile energy storage charging vehicle are cascade charged.

[0033] The output end of the AC power supply device (three-phase four-wire) is electrically connected to the charging end of the battery module through the AC input module and the DC contactor, and the output end of the fixed DC charging pile (DC pile) is electrically connected to the charging end of the battery module through the DC contactor; the battery module is electrically connected to the charging gun through the DC conversion module, and the charging of the electrical equipment is realized through the charging gun, and the electrical equipment includes an electric vehicle; the control device is electrically connected to the battery module for obtaining the charge and discharge information of the battery module. Among them, a fuse can also be provided on the DC contactor to improve safety. The mobile energy storage charging vehicle may include multiple gun heads (charging guns), a charging base for storing the gun heads, and a coil.

[0034] It can be considered that the control device is responsible for monitoring and managing the charge and discharge management of the battery module of the entire energy storage vehicle, AC and DC input management, control of the DC contactor, and regulation of the DC conversion module. The battery module is the energy storage unit of the mobile energy storage charging vehicle, which can store a large amount of electrical energy and provide the required power for electrical equipment. The AC input module allows the mobile energy storage charging vehicle to convert AC power from the AC power grid into DC power and store it in the battery module. The DC contactor is used to control the electrical connection between the battery module and external equipment (such as fixed DC charging piles or electrical equipment) to realize AC charging or DC charging of the mobile energy storage charging vehicle. The DC conversion module is responsible for converting the DC power of the battery module into a voltage and current suitable for the output of the charging gun to match the charging needs of electrical equipment (such as electric vehicles).

[0035] At the same time, the battery modules of each mobile energy storage charging vehicle are connected through cascade charging, allowing power to flow between different battery modules to optimize energy management and increase system flexibility. Cascade charging generally refers to connecting multiple battery modules in series or parallel through electrical connections, allowing power to be transferred between them. In a cascade charging connection, power can flow from one battery module to another, depending on the charge state and power requirements of each module.

[0036] Although some of the relevant charging piles also support intelligent scheduling and remote monitoring functions, their overall intelligence level is relatively low. When users use traditional charging piles in special circumstances such as sudden power outages, natural disasters or remote areas, they need more manual operation and attention. The advantage of this embodiment is that the various mobile energy storage charging vehicles in the mobile energy storage charging system are not restricted by the geographical location of fixed charging stations, and can be moved to different locations as needed to provide charging services for electric vehicles and other electrical equipment. In the event of natural disasters, power outages or other emergencies, mobile energy storage charging vehicles can be quickly deployed to the affected areas to provide necessary charging services for electrical equipment. Since mobile energy storage charging vehicles can be flexibly deployed, the need to build fixed charging stations in remote areas or temporary demand locations is reduced, thereby reducing infrastructure investment costs. Mobile energy storage charging vehicles can charge when the grid load is low and provide power support during peak hours, which helps to balance the grid load and enhance the stability of the grid.

[0037] In summary, the mobile energy storage charging system provides a flexible charging solution that can meet the charging needs of power-consuming devices in different scenarios. For example, it can be quickly deployed to areas affected by power outages to provide emergency power support for critical facilities and electric vehicles. After a natural disaster, even if the traditional power grid is damaged, the individual mobile energy storage charging vehicles in the mobile energy storage charging system can serve as an independent power source, providing temporary charging services to the disaster area and supporting the operation of rescue vehicles and equipment. Through cascade charging, the charging and discharging strategies of the battery modules of each mobile energy storage charging vehicle can be flexibly adjusted according to actual needs.

[0038] As an example, in one charging scenario, a mobile energy storage charging vehicle receives power from a fixed DC charging pile or other cascaded charging mobile energy storage charging vehicle. In another charging scenario, a mobile energy storage charging vehicle charges using power from an AC380V distribution cabinet. In a discharge scenario, a mobile energy storage charging vehicle drives alongside an electric vehicle and charges it.

[0039] In one embodiment, the AC input module includes an input circuit breaker, an AC contactor and an AC-DC converter. The input end of the input circuit breaker is connected to the output end of the AC power supply device, and the output end of the input circuit breaker is connected to the AC-DC converter through the AC contactor to realize AC-DC conversion of the input AC power.

[0040] The AC input module is responsible for converting AC power into DC energy for storage in the battery module. The input circuit breaker is the first line of defense connected to the output of AC-powered equipment, providing overload and short-circuit protection. For example, when the current exceeds a set value, the input circuit breaker automatically disconnects the circuit to prevent electrical fires and equipment damage. The AC contactor is a switching device used to frequently connect and disconnect AC circuits. It connects the output of the input circuit breaker to the AC-DC converter, connecting and disconnecting the power supply based on control signals, thereby controlling the AC input. The AC-DC converter receives AC power from the AC contactor and, through rectification and voltage regulation, converts it into DC power suitable for battery storage.

[0041] The advantage of this approach is that the input circuit breaker, AC contactor, and AC / DC converter are integrated into a single module, simplifying system design and installation and facilitating maintenance and upgrades. Furthermore, AC power can be obtained from various AC power sources (such as the grid and generators), increasing the system's applicability and flexibility.

[0042] In one embodiment, the control device includes a battery management module, a power distribution module, a central control module, and a temperature management module; the battery management module is electrically connected to the battery module and is used to monitor the voltage and current data of the battery module; the power distribution module is electrically connected to the central control module and is arranged between the battery module and the electrical equipment, and is used to distribute the power output of the battery module; the temperature management module is electrically connected to the central control module and is arranged on the battery module for obtaining the temperature data of the battery module; the central control module is used to obtain the voltage, current and temperature data of the battery module and generate a charging strategy.

[0043] The battery management module (BMS) monitors and manages battery module parameters such as voltage and current to ensure safe operation. Electrically connected to the battery modules, the BMS monitors key parameters such as voltage, current, and temperature in real time. Using this data, it assesses the module's status and ensures safe and efficient operation. The BMS also controls the battery's charging and discharging processes, preventing potential battery damage from overcharging, over-discharging, overheating, and short circuits. The power distribution unit (PDU) is electrically connected to the central control module and located between the battery modules and power-consuming devices. It controls the distribution of power to various loads, such as electric vehicle charging ports and the system's internal power supply, based on predetermined priorities and needs. The central control unit (CCU) receives data from the BMS, PDU, TMS, and other modules and makes decisions based on this data, such as adjusting charging strategies and optimizing energy usage. The temperature management module (TMS) monitors battery temperature.

[0044] The advantage of this is that the modular design makes it easier to maintain and upgrade the various submodules of the control device, reducing the maintenance cost of the system.

[0045] In one embodiment, the control device further includes a background system controller and a 4G communication module. The background system controller is electrically connected to the central control module and is remotely connected to the upper background set on the cloud platform through the 4G module.

[0046] The background system controller is responsible for processing data from the central control unit (CCU) and performing more complex data analysis, storage and management tasks. It can be connected to the central control module through a wired communication to ensure the stability and real-time performance of data transmission. The 4G communication module is a wireless communication unit in the control device. It uses the fourth-generation mobile communication technology to achieve high-speed data transmission, enabling the background system controller to establish a wireless connection with the upper background of the cloud platform through the 4G network to achieve remote data transmission and reception. The cloud platform is a remote server system that can store, process and analyze data collected from multiple mobile energy storage charging vehicles. It can be considered that through the 4G communication module, the background system controller can upload data to the cloud platform and receive instructions and updates from the cloud platform.

[0047] The benefit of this approach is that operators can remotely monitor the status of each mobile energy storage charging vehicle in the mobile energy storage charging system through the cloud platform. The cloud platform provides large-scale data storage and analysis capabilities, which helps to deeply understand system performance, optimize operational strategies, and improve overall system performance.

[0048] In one embodiment, the mobile energy storage charging vehicle further includes a display screen, which is electrically connected to the central control module and is configured to display the voltage, current, and temperature data of the battery module. In other words, the mobile energy storage charging vehicle integrates a display screen as part of the user interface, which is electrically connected to the central control module (CCU) and is configured to display key battery module data in real time.

[0049] The benefit of this is that the display provides an intuitive interface, allowing operators to quickly check the status of the battery module without complex operations or additional equipment.

[0050] In one embodiment, the mobile energy storage charging vehicle further includes an AC power meter and a DC power meter; the AC power meter is arranged between the input circuit breaker and the central control module, and is used to obtain the power input status from the AC power supply device to the battery module, and display it using the display screen; the DC power meter is arranged between the output end of the DC conversion module and the central control module, and is used to obtain the power output status from the battery module to the power-consuming equipment, and display it using the display screen.

[0051] The AC energy meter, installed between the input circuit breaker and the central control unit (CCU), measures the power input from AC-powered equipment to the battery module. It records AC power consumption and provides accurate energy metering. The DC energy meter, installed between the output of the DC converter module and the CCU, measures the power output from the battery module to the power-consuming equipment, providing energy consumption data for these devices and ensuring efficient energy distribution and utilization. A display provides real-time energy consumption information, enabling operators to intuitively understand the system's energy usage.

[0052] The benefit is that the AC and DC energy meters provide precise energy measurement, ensuring that both energy input and output are accurately recorded and monitored. The data display provided by the display increases system transparency, allowing users to clearly understand the energy consumption during the charging process.

[0053] In one embodiment, the battery module includes a plurality of detachable energy storage battery units.

[0054] The battery module, composed of multiple removable energy storage battery cells, provides flexibility and convenience in mobile energy storage and charging systems. Specifically, the battery module adopts a modular design and consists of multiple independent energy storage battery cells, each of which can independently store electrical energy. Due to the removable energy storage battery cells, if the performance of a storage battery cell deteriorates or is damaged, it can be quickly replaced without replacing the entire battery module. At the same time, the number of energy storage battery cells can be flexibly increased or decreased to adjust the total energy storage capacity of the battery module according to energy storage needs and space constraints.

[0055] The advantage is that the removable energy storage battery cells simplify maintenance, reducing maintenance costs and downtime. By replacing degraded energy storage battery cells, the service life of the entire battery module can be extended. The modular and removable design provides a high degree of flexibility, allowing the energy storage capacity to be quickly adjusted according to different application requirements.

[0056] In one embodiment, another DC contactor and a fuse are provided between the DC conversion module and the charging gun.

[0057] The DC converter module converts the DC power from the battery module into a voltage and current suitable for the output of the charging gun. The DC contactor acts as a control switch, controlling the circuit connection between the battery module and the charging gun. Specifically, the contactor can be controlled by the central control unit (CCU) to connect or disconnect the circuit based on charging requirements or safety logic. The fuse acts as an overcurrent protection device. When the current exceeds the rated value of the fuse, the fuse will disconnect the circuit to prevent overcurrent from damaging equipment or causing safety accidents.

[0058] The benefit is that the fuse provides an additional layer of safety, preventing abnormal current flow caused by short circuits or overloads, protecting the battery module and charging connector. The combination of the DC contactor and fuse protects the charging connector and the electric vehicle's charging port, reducing the risk of electrical failure. When maintenance or battery module replacement is required, the DC contactor can be disconnected to safely shut off power, making it easier for personnel to operate.

[0059] In one embodiment, the mobile energy storage charging vehicle further includes a movable remote control handle, which is wirelessly connected to a drive module of the mobile energy storage charging vehicle for controlling the movement of the mobile energy storage charging vehicle.

[0060] The remote control handle can be considered a handheld remote control device that contains buttons, joysticks, or other control mechanisms for sending control signals. The drive module is part of the mobile energy storage charging vehicle and is responsible for responding to the signals sent by the remote control handle and performing corresponding actions, such as starting, stopping, and steering the mobile energy storage charging vehicle. The remote control handle and the drive module communicate wirelessly to transmit operating instructions. In specific applications, the signals sent by the remote control handle can be transmitted to the charging vehicle's drive module, which interprets the signals and controls the vehicle's movement. The connection between the remote control handle and the mobile energy storage charging vehicle's drive module can be Bluetooth or infrared communication.

[0061] The advantage of this is that when charging services need to be deployed quickly, the remote control handle can quickly move the charging vehicle to the designated location. In specific applications, it can realize the charging pile to find the vehicle, saving the time of the vehicle looking for the charging pile.

[0062] In the embodiments of the present application, "at least one" refers to one or more, and "more" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can represent: a, b, c, a and b, a and c, b and c, a and b and c, where a, b and c can be single or multiple. It is worth noting that "at least one" can also be interpreted as "one or more items".

[0063] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto.
