[0045] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0046] This application discloses a mobile storage and charging device. By sequentially arranging a first functional area, a second functional area, and a third functional area along a first axial direction in the housing, and arranging a charging sub-area and a control sub-area along a second axial direction in the third functional area, the battery module is arranged in the first functional area, the power module is arranged in the second functional area, the charging head is arranged in the charging sub-area, and the control module is arranged in the control sub-area, the modular layout allows for a more rational arrangement of components within the housing, improving space utilization, reducing cable usage, and increasing installation and maintenance efficiency. At the same time, it makes the overall size of the device smaller and reduces the floor space occupied.

[0047] like Figures 1-15 As shown, the mobile storage and charging device includes:

[0048] The housing 100 has four circumferential surfaces: a first end surface 111, a second end surface 112, a third side surface 113, and a fourth side surface 114. The first end surface 111 and the second end surface 112 are positioned opposite each other, and the direction from the first end surface 111 to the second end surface 112 is the first axial direction. The third side surface 113 and the fourth side surface 114 are positioned opposite each other, and the direction from the third side surface 113 to the fourth side surface 114 is the second axial direction. The first axial direction is perpendicular to the second axial direction. The housing 100 includes a first functional area 121, a second functional area 122, and a third functional area 123 arranged sequentially along the first axial direction. The third functional area 123 includes a charging sub-area and a control sub-area 1231 arranged along the second axial direction.

[0049] Battery module 130 is located in the first functional area 121;

[0050] The power module 140 is located in the second functional area 122 and is connected to the battery module 130 for power conversion.

[0051] The charging head, located in the charging sub-area, is connected to the power module 140 and can charge the external electrical device after it is plugged in.

[0052] The control module 150 is located in the control sub-area 1231 and is connected to the power module 140.

[0053] In this embodiment, the mobile energy storage and charging device can be placed entirely on a vehicle (such as a truck or forklift) and transported to a designated location for use, such as for emergency power supply or charging electric vehicles. The housing 100 of the mobile energy storage and charging device includes a first functional area 121, a second functional area 122, and a third functional area 123 arranged sequentially along a first axial direction. The third functional area 123 includes a charging sub-area and a control sub-area 1231 arranged along a second axial direction. A battery module 130 is disposed in the first functional area 121 and is capable of storing and releasing electrical energy. A power module 140 is disposed in the second functional area 122 and connected to the battery module 130, used for energy conversion and transmission of control signals.

[0054] A charging head is located in the charging sub-area and is connected to the power module 140. After an external electrical device is plugged into the charging head, the electrical energy output from the battery module 130 is converted by the power module 140 and reaches the charging head, which then charges the external electrical device. The charging head can be a charging gun or a charging plug of other forms. Preferably, the charging head is a DC charging head used to provide DC power to the external electrical device; more preferably, the charging head is a DC charging gun, and the external electrical device is a DC electrical device such as an electric vehicle. In some embodiments of this application, when the charging head is a charging gun, a gun holder for placing the charging gun is provided in the charging sub-area, thereby preventing damage to the charging gun caused by shaking back and forth in the charging sub-area and improving the reliability of the charging gun.

[0055] The control module 150 is located in the control sub-area 1231 and is connected to the power module 140. It is used to control the power supply and charging process of the mobile energy storage and charging device.

[0056] The mobile energy storage and charging device of this application embodiment achieves a modular layout by sequentially arranging a first functional area 121, a second functional area 122, and a third functional area 123 along a first axial direction in the housing 100, and arranging a charging sub-area and a control sub-area 1231 along a second axial direction in the third functional area 123. The battery module 130 is arranged in the first functional area 121, the power module 140 is arranged in the second functional area 122, the charging head is arranged in the charging sub-area, and the control module 150 is arranged in the control sub-area 1231. This allows for a more compact arrangement of components, improves the utilization rate of the internal space of the mobile energy storage and charging device, reduces the size of the device, reduces the amount of cables used, and improves installation and maintenance efficiency.

[0057] In some embodiments of this application, the mobile storage and charging device further includes:

[0058] like Figure 8As shown, the liquid cooling module 160 is disposed in the second functional area 122 and located below the power module 140. It is connected to the power module 140 and receives power and control signals from the power module 140. It is used to circulate the coolant in the liquid cooling flow path of the battery module 130 to cool the battery module 130. Each battery pack 132 of the battery module 130 has a liquid cooling flow path to prevent the battery pack 132 from overheating during frequent charging and discharging.

[0059] like Figure 2 and Figure 14 As shown, panel 170 is located in the third functional area 123 and below control module 150, connecting control module 150 and power module 140. Panel 170 has a power supply interface for external power supply and a charging interface for charging battery module 130. Panel 170 faces the second end face 112, or panel 170 may be located on the second end face 112. Figure 2 In the embodiment shown, the panel 170 is recessed a certain distance from the second end face 112 in the opposite direction of the first axis. This is because the panel 170 is provided with a variety of interfaces to prevent these interfaces from protruding from the surface of the second end face 112 and interfering with other objects during transportation or use.

[0060] In this embodiment, the liquid cooling module 160 obtains power from the battery module 130 via the power module 140, or from an external power source connected to the panel 170 via the power module 140. The liquid cooling module 160 receives a control signal from the power module 140 to circulate the coolant in the liquid cooling path of the battery module 130, thereby cooling the battery module 130. Since the liquid cooling module 160 is positioned below the power module 140, coolant leakage into the power module 140 is prevented, thus improving the operational reliability of the power module 140 while ensuring the battery module 130 operates at a suitable temperature. Furthermore, the liquid cooling module 160 is located in the second functional area, rather than the first functional area where the battery module 130 is located. Even if coolant leakage occurs, it will not affect the normal operation of the battery module 130 in a short period. The liquid cooling module 160 is positioned close to the battery module 130, avoiding the use of excessively long coolant flow paths.

[0061] Panel 170 connects control module 150 and power module 140. Panel 170 is provided with a power supply interface for external power supply and a charging interface for charging battery module 130.

[0062] In some embodiments of this application, such as Figure 16As shown, the power supply interface includes multiple AC power supply interfaces 171, each of which can be matched with various plug types or current ratings. Combined with a DC charging head, this mobile energy storage and charging device can not only charge DC-powered devices (such as electric vehicles) but also charge various AC-powered devices, meeting the power needs of a variety of devices.

[0063] The charging interfaces on panel 170 include an AC charging interface 172 and a DC charging interface 173, which can charge the battery module 130 via AC or DC power. The AC charging interface 172 includes an AC mains charging interface, a diesel engine charging interface, etc.; the DC charging interface 173 includes a charging gun interface for an external charging station, etc. The charging gun interface for the external charging station is used to electrically connect the charging gun of the external charging station to this mobile energy storage and charging device to charge the battery module 130. The versatility of the charging interfaces allows users to charge this mobile energy storage and charging device with different forms of electrical energy, making it adaptable to various usage environments and scenarios, ensuring a sufficient power supply at all times.

[0064] Furthermore, since the panel 170 is located below the control module 150, after the mobile charging device is installed on the vehicle, the panel 170 can be positioned in a convenient location for user operation. This arrangement makes the mobile charging device suitable for both ground and elevated use, improving the user experience. In some embodiments of this application, the panel 170 also includes a start / stop button for the mobile charging device, allowing users to easily start and stop the device as needed.

[0065] In some embodiments of this application, such as Figure 12 and Figure 5 As shown, the charging sub-region includes a first charging sub-region 1232 and a second charging sub-region 1233. At least one charging head is provided in each of the first charging sub-region 1232 and the second charging sub-region 1233. The first charging sub-region 1232, the control sub-region 1231, and the second charging sub-region 1233 are arranged sequentially along a second axial direction. Preferably, the first charging sub-region 1232 faces the third side surface 113, the second charging sub-region 1233 faces the fourth side surface 114, and the control sub-region 1231 faces the second end surface 112.

[0066] In this embodiment, at least one charging head is provided in both the first charging sub-area 1232 and the second charging sub-area 1233, thereby increasing the number of charging heads and improving the power supply performance of the mobile energy storage and charging device. Users can use the charging heads in the first charging sub-area 1232, the second charging sub-area 1233, or both simultaneously, as needed. By arranging the first charging sub-area 1232, the control sub-area 1231, and the second charging sub-area 1233 sequentially along the second axis, the charging heads are positioned on both sides of the control module 150, which not only makes reasonable use of the space on both sides of the control module 150 but also reduces the width of the mobile energy storage and charging device, thus reducing the overall size of the mobile energy storage and charging device.

[0067] In some embodiments of this application, such as Figure 1 and Figure 3 As shown, the first charging sub-area 1232 faces the third side 113, and the second charging sub-area 1233 faces the fourth side 114. The first charging sub-area 1232 is provided with a first charging compartment door 1131 on the third side 113; the second charging sub-area 1233 is provided with a second charging compartment door 1141 on the fourth side 114.

[0068] In this embodiment, by providing a first charging compartment door 1131 and a second charging compartment door 1141, dust and other foreign objects can be prevented from entering the first charging sub-area 1232 and the second charging sub-area 1233, improving the reliability of the charging head. Simultaneously, it facilitates user access to and from the charging head, enhancing the user experience. Furthermore, since the first charging compartment door 1131 and the second charging compartment door 1141 are respectively located on the third side 113 and the fourth side 114, the width of the mobile charging storage device is reduced.

[0069] In some embodiments of this application, the first charging sub-area 1232 and the second charging sub-area 1233 both include a first space and a second space, with the charging head housed in the first space; the second space is located directly above the first space.

[0070] In this embodiment, by dividing the first charging sub-area 1232 and the second charging sub-area 1233 into a first space and a second space respectively, the charging head is housed in the lower first space, which makes it convenient for the user to pick up and put down the charging head. At the same time, the second space can accommodate other components according to the user's needs, such as a cable organizer corresponding to the charging head, thereby making more reasonable use of the space in the first charging sub-area 1232 and the second charging sub-area 1233.

[0071] In some embodiments of this application, the first charging sub-area 1232 and / or the second charging sub-area 1233 further include a third space, which is used to accommodate a replenishing water tank. The replenishing water tank is connected to the liquid cooling module 160 and is used to display the liquid level of the coolant in the liquid cooling module 160 and to replenish the coolant to the liquid cooling module 160. The third space is located directly above the second space.

[0072] In this embodiment, since the charging head is a device that users frequently use, users will often open the first charging sub-area 1232 and the second charging sub-area 1233. By accommodating the replenishing water tank in the third space, users can easily pay attention to whether the liquid level in the replenishing water tank is normal at any time, and replenish the coolant to the liquid cooling module 160 in time when the liquid level is low, thereby improving the operational reliability of the liquid cooling module 160.

[0073] In some embodiments of this application, such as Figure 13 As shown, the control module 150 includes a control frame 151 and control components 152 fixed on the control frame 151 (only some control components are shown in the figure); the control frame 151 is detachably connected to the housing 100; as Figure 7 As shown, the power module 140 includes a power frame 141 and power components 142 fixed on the power frame 141; the power frame 141 is detachably connected to the housing 100.

[0074] Both the control frame 151 and the power frame 141 are equipped with a large number of components. By detachably connecting the control frame 151 and the power frame 141 to the housing 100, various components can be installed on the control frame 151 and the power frame 141 respectively during assembly. After installation, the control frame 151 and the power frame 141 are then fixedly connected to the housing 100. This detachable frame design greatly facilitates the assembly of components, the debugging of the entire machine, and the adjustment of the component layout.

[0075] In this embodiment, the control components 152 include, for example, an EMS (Energy Management System), an electricity meter, and a power supply unit that supplies power to the control module 150. By providing a control frame 151 that is detachably connected to the housing 100 in the control module 150, the control module 150 can be installed and maintained more efficiently.

[0076] Power components 142 may include at least one of the following: an AC-DC power unit, a DC-AC power unit, a DC-DC power unit, and a main circuit breaker. The AC-DC power unit converts external AC power to DC power to charge the battery module 130, for example, using AC power or a diesel generator. The DC-AC power unit converts the DC power output from the battery module 130 to AC power to provide AC power to external devices, for example, through the AC power interface 171 on the panel 170. The DC-DC power unit converts the DC power output from the battery module 130 to a target DC power to provide DC power to external devices, for example, through the charging gun in the charging sub-area to power an electric vehicle. The main circuit breaker enables the start and stop of the mobile charging and storage device. By providing a power rack 141 that is detachably connected to the housing 100, the installation and maintenance of the power module 140 can be performed more efficiently.

[0077] It should be noted that those skilled in the art can flexibly set different control components 152 in the control module 150 as needed, and set different power components 142 in the power module 140 as needed. The different setting methods of control components 152 and power components 142 do not affect the scope of protection of this application.

[0078] In some embodiments of this application, such as Figure 13 As shown, the control module 150 also includes a first quick-connect connector 153; as Figure 7 As shown, the power module 140 also includes a second quick connector 143; the control module 150 and the power module 140 are connected for power and signal through the first quick connector 153 and the second quick connector 143; preferably, the first quick connector 153 is disposed on the control frame 151 and the second quick connector 143 is disposed on the power frame 141.

[0079] In this embodiment, by setting a first quick connector 153 in the control module 150 and a second quick connector 143 in the power module 140, after fixing the control module 150 and the power module 140 on the housing 100, it is only necessary to connect one end of the connecting cable to the first quick connector 153 and the other end of the connecting cable to the second quick connector 143 to achieve a quick connection of the power line and signal line between the control module 150 and the power module 140.

[0080] In some embodiments of this application, the second functional area 122 further includes:

[0081] like Figure 9 and Figure 12As shown, the first cooling fan 144 is mounted on the power module 140 and close to the third side 113, and is used to cool the power module 140.

[0082] like Figure 11 As shown, the second cooling fan 1142 is installed on the housing 100 and close to the inner side of the fourth side 114, and is used to dissipate heat from the power module 140; the first cooling fan 144 and the second cooling fan 1142 have the same airflow direction.

[0083] like Figure 8 and Figure 11 As shown, the liquid cooling module 160 includes a third cooling fan 161, which is used to dissipate heat from the coolant. The third cooling fan 161 has the same airflow direction as the first cooling fan 144 and the second cooling fan 1142.

[0084] The first cooling fan 144, the second cooling fan 1142, and the third cooling fan 161 can all be powered by the battery module 130 of the mobile energy storage device.

[0085] Preferably, such as Figure 16 As shown, panel 170 also includes an auxiliary power interface 174, through which the second cooling fan 1142 and liquid cooling module 160 are electrically connected. When an external power source is connected to the auxiliary power interface 174, the second cooling fan 1142 and liquid cooling module 160 no longer draw power from the battery module 130 of the mobile charging device, but are directly powered by the external power source. At the same time, the third cooling fan 161 also no longer draws power from the battery module 130 of the mobile charging device, but is directly powered by the external power source, thus reducing the power consumption of the battery module 130.

[0086] In this embodiment, the first cooling fan 144 can be one or more. By integrating the first cooling fan 144 into the power module 140, efficient heat dissipation of the power module 140 is achieved, improving the reliability of the power module 140. The second cooling fan 1142 can be one or more. By setting the second cooling fan 1142 on the housing 100, the heat dissipation efficiency of the power module 140 can be improved. When both the first cooling fan 144 and the second cooling fan 1142 are set, their air intake and exhaust directions are the same. For example, by having the first cooling fan 144 blow air onto the power module 140, while the second cooling fan 1142 draws air from the power module 140 and blows it to the outside of the housing 100, the air intake and exhaust directions of the first cooling fan 144 and the second cooling fan 1142 are made to be the same. Alternatively, by having the second cooling fan 1142 blow air onto the power module 140, while simultaneously having the first cooling fan 144 draw air from the power module 140 and blow it out of the housing 100, the airflow directions of the first cooling fan 144 and the second cooling fan 1142 can be made to be the same.

[0087] There can be one or more third cooling fans 161. By setting a third cooling fan 161 in the liquid cooling module 160 and making the air inlet and outlet directions of the third cooling fan 161 the same as those of the first cooling fan 144 or the second cooling fan 1142, the air inlet and outlet directions inside the housing 100 can be made uniform while ensuring the normal operation of the liquid cooling module 160, thereby improving the heat dissipation efficiency of the power module 140.

[0088] In some embodiments of this application, when the first cooling fan 144 blows air onto the power module 140, while the second cooling fan 1142 draws air from the power module 140 and blows it towards the outside of the housing 100, the power module 140 is sequentially provided with an air inlet area, a middle area, and an air outlet area along the second axial direction; for example Figure 10 As shown, a protective cover 145 is provided in the central area, and components are housed in the protective cover 145; the opening of the protective cover 145 faces the air outlet area.

[0089] In this embodiment, the protective cover 145 houses components such as a DC contactor that automatically distributes maximum output power, a molded case circuit breaker that controls the on / off state of the input power, and a fuse that protects the circuit. The components housed in the protective cover 145 generate relatively low heat and do not require air cooling, but they cannot operate in high-temperature environments for extended periods. The power conversion components, such as the ACDC module, located in the air inlet area generate relatively high heat, while the components located in the middle and air outlet areas generate very little heat. Because the components in the middle area are very close to the air inlet area, the hot air blowing from there is still quite hot; therefore, a protective cover 145 is provided to prevent the hot air from directly hitting these components, reducing the impact of the hot air on the components inside the protective cover 145. The components located in the air outlet area are relatively far from the air inlet area, where the air temperature has already been significantly reduced; therefore, the components in the air outlet area do not require a protective cover 145.

[0090] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, the battery module 130 includes a battery rack 131, which is fixedly connected to the housing 100 in a non-detachable manner; the battery rack 131 includes multiple layers, each layer of which can hold at least one battery pack 132; there is a certain distance between the bottom surface of the bottom layer of the battery rack 131 and the inner bottom surface of the housing 100.

[0091] In this embodiment, by setting up the battery rack 131, multiple battery packs 132 can be efficiently arranged. By maintaining a certain distance between the bottom surface of the lowest layer and the inner bottom surface of the housing 100, space can be reserved for the forklift arm, making it easy for the forklift to install each battery pack 132 sequentially on the battery rack 131. On the other hand, the battery packs 132 can have a certain height, so even if coolant leaks to the bottom surface of the housing 100, it can prevent the coolant from affecting the battery packs 132. At the same time, a heat dissipation space can be formed at the bottom of the battery module 130, which can improve the heat dissipation efficiency of the battery module 130.

[0092] In some embodiments of this application, such as Figures 1-4 As shown, the first functional area 121 is provided with a first door 1211 on the third side 113 and / or the fourth side 114 respectively, and the first door 1211 corresponds to the battery module 130.

[0093] The second functional area 122 is provided with a second door 1221 on the third side 113 and / or the fourth side 114 respectively. The second door 1221 corresponds to the power module 140 and has a grille structure.

[0094] The third functional area 123 is provided with a third door 1121 on the second end face 112. The third door 1121 corresponds to the control module 150. The control module 150 also includes a human-machine interface 154, which is located on the third door 1121.

[0095] In this embodiment, a first door 1211 is provided on the third side 113 and / or the fourth side 114 to facilitate the installation and maintenance of the battery module 130 by the user. A second door 1221 is provided on the third side 113 and / or the fourth side 114 to facilitate the installation and maintenance of the power module 140 by the user. Due to the use of a grille structure, a heat dissipation channel is formed for the power module 140, ensuring the heat dissipation effect of the power module 140. A third door 1121 is provided on the second end face 112 to facilitate the installation and maintenance of the control module 150 by the user. The human-machine interface 154 integrates the control interface for the EMS, signal acquisition board, and relays of the control switch. By providing the human-machine interface 154 on the control module 150, the user can input control commands for the control module 150 as needed, improving the user experience.

[0096] In some embodiments of this application, the mobile storage and charging device further includes at least one of the following:

[0097] like Figure 1 As shown, multiple lifting rings 180 are set on the top of the housing 100 for lifting the mobile storage and charging equipment;

[0098] like Figure 1 As shown, the fork hole structure 190 is located at the bottom of the housing 100 for the insertion of a forklift arm for lifting the mobile storage and charging equipment.

[0099] A movable chassis is located at the bottom of the housing 100 and is detachably connected to the housing 100.

[0100] In this embodiment, multiple lifting rings 180 are provided on the top of the housing 100 to facilitate the lifting and movement of the mobile storage and charging device by a crane via each lifting ring 180. A forkhole structure 190 is provided at the bottom of the housing 100 to facilitate the movement of the mobile storage and charging device using a forklift. A movable chassis is provided with casters, enabling the mobile storage and charging device to be moved via the movable chassis at the bottom of the housing 100.

[0101] In some embodiments of this application, such as Figure 5As shown, a partition 124 is provided between the first functional area 121 and the second functional area 122. By setting the partition 124, the liquid cooling module 160 is placed in a sealed compartment, which can completely isolate the liquid cooling module 160 and the battery module 130, thereby preventing the coolant in the liquid cooling module 160 from leaking into the battery module 130 and improving the reliability of the battery module 130.
