Description

Technical Field

[0001] The utility model relates to the technical field of locomotives, in particular to an electric storage vehicle and an electric locomotive. Background Art

[0002] Previously, locomotives were categorized as steam, diesel, and gas turbine locomotives.

Rail wheels are also provided on the flat car 22, and the flat car 22 is an unpowered vehicle. By arranging the energy storage system 21 on the flat car 22, it is convenient to construct a storage vehicle 2 that can travel along the rails. The entire space on the top of the flat car 22 is the energy storage system 21, which can be loaded with a large number of battery packs to store a large amount of electrical energy to meet the endurance requirements of the electric locomotive.

[0053] In some possible embodiments, the energy storage system includes a high-voltage box 213, a DC-DC converter 214 and a junction cabinet 215.

[0054] The energy storage system 21 includes not only battery packs 212 but also DC-DC converters 214 for voltage regulation. These are ultimately connected to a combiner cabinet 215, which connects the voltage outputs of the connected battery packs 212 in parallel or by shunting them to improve the stability, reliability, and safety of each battery pack 212. Each battery storage vehicle 2 constitutes an independent power supply unit, and the number of battery storage vehicles 2 can be selected based on actual needs to meet the range requirements of the electric locomotive.

[0055] In some possible implementations, the energy storage system includes a water cooling unit 216, which is disposed in the container 211 and connected to the battery packs 212 via water cooling pipes. The water cooling unit 216 is used to cool each battery pack 212, thereby maintaining good heat dissipation and improving safety.

[0056] Optionally, the container 211 has a frame and a skin, with the skin covering the frame to enclose a cavity, within which the battery pack 212, high-voltage box 213, water-cooling unit 216, DC-DC converter 214, and combiner cabinet 215 are disposed. The skin covers the internal structures to prevent rainwater and impurities from entering.

[0057] The skin may be provided with heat dissipation holes for discharging hot air from the skin to avoid excessive heat in the container 211 .

[0058] In some possible embodiments, the skeleton includes a bottom frame 2111, a top frame 2112 and several columns, the bottom frame 2111 is connected to the flat car 22, the top frame 2112 and the bottom frame 2111 are spaced apart, each of the columns is arranged between the top frame 2112 and the bottom frame 2111, and the columns are respectively connected to the top frame 2112 and the bottom frame 2111, the battery pack 212, the high-voltage box 213, the DC-DC converter 214 and the junction cabinet 215 are all arranged between the top frame 2112 and the bottom frame 2111 of the skeleton, and are located between the top frame 2112 and the bottom frame 2111.

The DC-DC converter 214 and the junction box 215 are both installed on the bottom frame 2111. The cluster frame 217, the DC-DC converter 214 and the junction box 215 are arranged in sequence along the length direction of the storage vehicle 2.

[0060] Power interfaces 2114111 are provided at both ends of the container 211. These interfaces are electrically connected to the battery pack 212. Specifically, they are electrically connected to the combiner cabinet 215. These interfaces are used to connect the battery pack 212 of the energy storage system 21 to the power supply circuit of the electric locomotive's tractor 1, providing propulsion power for the tractor 1. The provision of these interfaces facilitates plug-in and unplugging connections with corresponding cables.

[0061] Optionally, the power interfaces 2114111 at both ends of the container 211 each include multiple shunt interfaces. By configuring the power interfaces 2114111 as multiple shunt interfaces, a large current can be shunted into multiple paths, thereby reducing circuit load and improving safety.

[0062] Example 2

[0063] See also Figure 5 as well as Figures 9 to 15As shown, the embodiment of the present application details the energy storage system 21 of the energy storage vehicle 2 of the electric locomotive, which includes a container 211, a cluster frame 217 and a plurality of battery packs 212. The container 211 has a top frame 2112 and a bottom frame 2111, which are connected to each other. The cluster frame 217 includes a plurality of longitudinal support frames 2171, each of which is arranged inside the container 211, and each of the longitudinal support frames 2171 is arranged in sequence along the length direction of the container 211. Each of the longitudinal support frames 2171 is fixedly connected to the top frame 2112 and the bottom frame 2111, and a plurality of horizontal support frames 2172 are arranged between two adjacent longitudinal support frames 2171. Each of the horizontal support frames 2172 is arranged in sequence along the longitudinal direction. The two ends of the horizontal support frame 2172 are fixedly connected to the two adjacent longitudinal support frames 2171, and a receiving cavity is formed between the upper and lower adjacent horizontal support frames 2172. Each of the battery packs 212 is housed in a corresponding housing. In the embodiment of the present application, by providing a cluster rack 217 within the container 211, a large number of battery packs 212 can be conveniently arranged to store a large amount of electrical energy to meet the endurance requirements of the electric locomotive.

[0064] In some possible implementations, see Figure 7 As shown, the bottom frame 2111 includes a plurality of structural beams 21111 arranged in sequence, each of the structural beams 21111 is arranged in sequence along the length direction of the container 211, and the structural beams 21111 extend along the width direction of the container 211. Figure 11 As shown, the longitudinal support frame includes multiple vertical beams 21711, each of which is spaced apart along the length of the structural beam 21111. Each of the vertical beams 21711 is fixedly connected to the structural beam 21111, and the horizontal support frame 2172 is connected to each of the vertical beams 21711. The longitudinal support frame includes multiple independent vertical beams 21711, each of which is independently fixed to the structural beam 21111 via fasteners. The entire horizontal support frame 2172 has a high structural strength and meets the requirements of supporting a large number of battery packs 212.

[0065] In some possible implementations, the longitudinal support frame 2171 includes a plurality of oblique beams 21712, each of which is located between two adjacent vertical beams 21711, with one end of the oblique beam 21712 connected to the bottom end of one vertical beam 21711, and the other end of the oblique beam 21712 connected to the top end of another vertical beam 21711. An oblique beam 21712 is provided between adjacent vertical beams 21711 on the support frame, with its ends connected to the top and bottom ends of the two vertical beams 21711, respectively, thereby reinforcing the longitudinal support frame 2171. The oblique beam 21712 divides the space between the two vertical beams 21711 into two triangular areas, forming two triangular structures, which significantly improves the structural strength and stability of the longitudinal support frame 2171.

[0066] In some possible implementations, see Figure 11 As shown, the longitudinal support frame 2171 includes a plurality of bases 21713, each of which is sequentially spaced along the length of the structural beam 21111. Each base 21713 is fixedly connected to two adjacent structural beams 21111, and the bottom ends of the vertical beams 21711 and the inclined beams 21712 are connected to the bases 21713. The vertical beams 21711 and the inclined beams 21712 can be directly connected or connected to the same base 21713, thereby improving the strength of the fixed structure.

[0067] In some possible implementations, the structural beam 21111 includes a web and flanges located on both sides of the web, and the base 21713 includes a bottom plate 217131 and a connecting plate. Figure 12 As shown, the bottom plate 217131 is connected to the flanges of two adjacent structural beams 21111. The connecting plate includes a first plate body 217132 connected to the bottom plate 217131 and a second plate body 217133 perpendicular to the first plate body 217132. The first plate body 217132 can be directly connected to the bottom plate 217131, and the second plate body 217133 is perpendicular to the bottom plate 217131. Figure 11 As shown, the vertical beam 21711 and the inclined beam 21712 are respectively connected to the bottom plate 217131 and the second plate body 217133. The setting of the connecting plate increases the structural strength of the connection between the vertical beam 21711 and the inclined beam 21712 and the base 21713, thereby enhancing the structural strength of the entire cluster frame 217.

[0068] In some possible implementations, see Figure 12As shown, the base 21713 includes two connecting plates, the second plate bodies 217133 of the two connecting plates are parallel, the vertical beam 21711 and the oblique beam 21712 both extend between the second plate bodies 217133 of the two connecting plates, and the vertical beam 21711 and the oblique beam 21712 both connect the two second plate bodies 217133 respectively.

[0069] By providing two connecting plates, the bottom ends of the vertical beam 21711 and the diagonal beam 21712 can extend between the second plates 217133 of the two connecting plates. The cross-section of the vertical beam 21711 can be larger than that of the diagonal beam 21712, and the cross-section of the vertical beam 21711 can be rectangular. The two opposing wall shells of the vertical beam 21711 are respectively connected to the second plates 217133 of the two connecting plates.

[0070] The top ends of the oblique beams 21712 are respectively connected to the top frame 2112 and the vertical beams 21711 , and the contact parts can be fixed by welding or by fasteners, which significantly improves the structural strength of the cluster frame 217 .

[0071] In some possible implementations, see Figure 12 As shown, the connecting plate includes a plurality of reinforcing plates 217134. Each reinforcing plate 217134 is located between the first plate 217132 and the second plate 217133, and respectively connects the first plate 217132 and the second plate 217133. The reinforcing plates 217134 are triangular in shape and are respectively connected to the first plate 217132 and the second plate 217133, thereby strengthening the overall structural strength of the first plate 217132 and the second plate 217133.

[0072] In some possible implementations, see Figure 10 As shown, the horizontal support frame 2172 includes multiple longitudinal beams 21721 and two transverse beams 21722. The two transverse beams 21722 are respectively connected to the vertical beams 21711 of two adjacent longitudinal support frames 2171. Each longitudinal beam 21721 is located between two transverse beams 21722. The longitudinal beams 21721 are sequentially spaced along the length of the transverse beams 21722. The ends of the longitudinal beams 21721 are respectively connected to the transverse beams 21722. The battery packs 212 are supported on the transverse beams 21722 and the longitudinal beams 21721. The horizontal support frame 2172 is a crisscross frame structure with light weight and high structural strength, which can meet the requirements of stable support and assembly of each battery pack 212.

[0073] In some possible implementations, see Figure 10As shown, the horizontal support frame 2172 includes a guide plate 21723, which is connected to the transverse beam 21722. The guide plate 21723 is provided with an outward-expanding guide fold 217231 on the side of the guide plate 21723 near the entrance of the accommodating cavity. When the battery pack 212 is loaded into the accommodating cavity, the two guide plates 21723 are respectively limited to the two sides of the battery pack 212. The guide fold 217231 is located on one side of the skin, which facilitates the insertion of the battery pack 212 into the accommodating cavity from the outside. One side of the guide fold 217231 is an outward-expanding structure, which plays a guiding role in the process of inserting the battery pack 212 from the entrance of the accommodating cavity into the accommodating cavity, reducing the difficulty of assembling the battery pack 212 and improving the assembly efficiency.

[0074] In some possible implementations, a connection hole is provided on the battery pack 212, through which one end of a fastener passes to connect to the horizontal support frame 2172. A flexible buffer is provided between the fastener and the battery pack 212, and / or between the battery pack 212 and the horizontal support frame 2172. The flexible buffer may be rubber, foam, or other elastic component, and the provision of the flexible buffer provides a shock-absorbing effect and reduces noise.

[0075] Example 3

[0076] The energy storage system for an electric locomotive provided in an embodiment of the present application is a modular energy storage system 21, comprising: a container 211, a combiner cabinet 215, a power interface 2114111, and multiple subsystems, each of which is disposed in the container 211. The subsystems include multiple battery packs, a high-voltage box 213, and a DC-DC converter 214. The battery packs are electrically connected to the high-voltage box 213, which is electrically connected to the DC-DC converter 214. The combiner cabinet 215 is disposed in the container 211 and is electrically connected to the DC-DC converters 214 of each subsystem. The power interface 2114111 is disposed in the container 211 and is electrically connected to the combiner cabinet 215. The power interface 2114111 can be connected to an external charging device to charge each battery pack 212. The power electrical interface 2114111 can also discharge. For example, the power electrical interface 2114111 is electrically connected to the traction vehicle 1 of the electric locomotive to provide the traction vehicle 1 with driving power.

[0077] The energy storage system 21 of this application provides multiple subsystems. When a subsystem fails, it does not affect the operation of other subsystems, thereby improving the stability of the energy storage system 21 and preventing a single subsystem failure from causing the entire system to shut down. Each battery pack 212 in the same subsystem can use batteries from the same batch, resulting in minimal variation in batteries within the same subsystem and excellent quality stability.

[0078] For example, the energy storage system 21 of the present application may include four subsystems, with DC-DC converters 214 used to boost or buck the DC voltage of the subsystems. The outputs of the DC-DC converters 214 on the DC side are all connected to a combiner cabinet 215, which houses the main circuit, control circuit, and control module.

[0079] In some possible implementations, each subsystem includes multiple clusters of battery packs 212 and multiple high-voltage boxes 213. Each cluster of battery packs 212 can include multiple battery packs 212 arranged longitudinally. Each high-voltage box 213 is electrically connected to at least one battery pack 212 in the cluster, and the subsystem's DC-DC converter 214 is electrically connected to each of the high-voltage boxes 213. A subsystem may include only one DC-DC converter 214, which can be connected to four high-voltage boxes 213, and each of the four high-voltage boxes 213 can be electrically connected to a cluster of battery packs 212.

[0080] In some possible implementations, the subsystem includes a plurality of cooling units, each cooling unit being connected to at least one battery pack 212 of a cluster.

[0081] Exemplarily, each subsystem includes only two cooling units, and the two cooling units are respectively connected to two clusters of battery packs 212. The cooling units can cool each battery pack 212 so that the battery packs 212 maintain a good operating condition.

[0082] In some possible implementations, a combiner cabinet 215 is disposed at one end of the container 211, and the battery packs 212 of each subsystem are disposed at the other end of the container 211. The DC-DC converters 214 of each subsystem are located between the combiner cabinet 215 and the battery packs 212. The centralized arrangement of the DC-DC converters 214 of each subsystem facilitates unified management and maintenance.

[0083] In this embodiment, the high-voltage box 213 is located in the installation area of each battery pack 212, and the high-voltage box 213, the DC-DC converter 214 and the junction box 215 are arranged in sequence along the length direction of the container 211, which facilitates the electrical connection between the high-voltage box 213 and the battery pack 212, the electrical connection between the DC-DC converter 214 and the high-voltage box 213, and the electrical connection between each DC-DC converter 214 and the junction box 215.

[0084] In some possible implementation schemes, at least two groups of the subsystems are respectively arranged on both sides of the container 211 in the width direction, and the subsystem structures on both sides of the container 211 in the width direction are symmetrically arranged, thereby facilitating assembly and making the entire vehicle structure symmetrical and the center of gravity centered.

[0085] Exemplarily, two groups of subsystems are respectively provided on both sides of the container 211 along the width direction, and a total of four subsystems are provided in the container 211.

[0086] In some possible implementations, the modular energy storage system 21 includes a cluster rack 217, which is disposed within the container 211. The battery packs 212 and high-voltage boxes 213 of each subsystem are mounted on the cluster rack 217. The cluster rack 217 provides more mounting locations to accommodate a large number of battery packs 212, high-voltage boxes 213, and water-cooling units 216.

[0087] In some possible implementations, see Figure 10 and Figure 11 As shown, the cluster rack 217 includes a plurality of longitudinal support frames 2171, each of which is disposed within the container 211 and spaced apart along the length of the container 211.

[0108] The auxiliary power interface 2114121 is arranged on the outer convex shell. In the height direction and the length direction of the energy storage system 21, the auxiliary power interface 2114121 is staggered with the power power interface 2114111 to avoid mutual interference between the two.

[0109] The auxiliary power interface 2114121 is connected to the junction box 215 and is used to connect to an external battery. The battery can be installed not on the storage car 2 but elsewhere on the electric locomotive, such as on the traction car 1 or other cars of the electric locomotive.

[0112] Example 6

[0113] The present embodiment of the application provides a detailed description of the energy storage system 21 of the electric locomotive's storage vehicle, which includes a container 211 and an auxiliary power interface 2114121. The container 211 has a cavity, within which are disposed a battery pack 212, a high-voltage box 213, a DC-DC converter 214, and a combiner cabinet 215.

[0114] The auxiliary power interface 2114121 is used to connect to an external battery. The battery can be installed elsewhere in the electric locomotive, such as on the traction vehicle 1 or other cars, rather than on the storage vehicle 2. This battery can be connected to the auxiliary power interface 2114121 to power important facilities within the energy storage system 21. This ensures that even if the storage vehicle 2 runs out of power, a stable external power source is still available to power these important facilities, ensuring the normal operation of the energy storage system 21. Important facilities include the control module, control circuits, water cooling unit 216, and firefighting equipment within the energy storage system 21.

[0115] The energy storage system 21 of the present application is provided with an auxiliary power interface 2114121 which can be conveniently connected to the traction vehicle 1 of the electric locomotive, and auxiliary power is provided by the traction vehicle 1 to ensure that when the energy storage system 21 is out of power, the control components and fire protection components can still operate normally and effectively.

[0116] In some possible implementations, the energy storage system 21 includes a control component, a fire protection component, and a battery cooling component. At least some of these components can be electrically connected to the auxiliary power interface 2114121.

[0118] In this embodiment, the auxiliary power interface 2114121 is arranged on the end frame 2113, which facilitates the electrical connection of the auxiliary power interfaces 2114121 of adjacent power storage vehicles 2, and also facilitates the connection of the auxiliary power interface 2114121 on the power storage vehicle 2 and the auxiliary power interface on the traction vehicle 1 of the electric locomotive through cables.

[0119] In some possible embodiments, the energy storage system 21 includes an interface shell 2114, which is located on the outside of the container 211 and is connected to the end frame 2113 of the container 211. The interface shell 2114 has an end shell plate away from the end frame 2113, and the auxiliary power interface 2114121 is arranged on the end plate shell.

[0120] In some possible implementations, a power interface 2114111 is further provided on the end shell plate, which is electrically connected to the combiner cabinet 215.

[0121] In some possible embodiments, the end shell plate has a main shell portion 211411 and an outer convex shell portion 211412, the outer convex shell portion 211412 protrudes from the main shell portion 211411, the auxiliary power interface 2114121 is arranged on the outer convex shell portion 211412, and the power power interface 2114111 is arranged on the main shell portion 211411.

[0122] Example 7

[0123] This embodiment of the present application provides an energy storage system 21 with monitoring functionality, comprising a container 211 and a monitoring assembly. Container 211 has a cavity within which are located a battery pack 212, a high-voltage box 213, a DC-DC converter 214, and a combiner cabinet 215. The battery pack 212 is electrically connected to the high-voltage box 213, which is electrically connected to the DC-DC converter 214, and the combiner cabinet 215 is electrically connected to the DC-DC converter 214. The monitoring assembly is disposed within container 211 and is configured to capture image and / or sound signals within container 211.

[0124] By installing a monitoring component within container 211, the present embodiment can obtain image and / or sound signals from within container 211, providing a basis for determining the operating status of energy storage system 21. The monitoring component allows for intuitive acquisition of images and videos from within container 211, eliminating the need for personnel to enter container 211. This reduces their workload and eases the difficulty of safety monitoring of energy storage system 21.

[0125] In some possible implementations, see Figure 5 As shown, container 211 includes a top frame 2112 and a bottom frame 2111. The cavity is formed between the top frame 2112 and the bottom frame 2111. The monitoring component is at least partially disposed on the top frame 2112. The top frame 2112 is high, and the monitoring component disposed on the top frame 2112 has a wide field of view, allowing the monitoring component to capture video images over a wider range.

[0126] In some possible implementations, the battery pack 212, DC-DC converter 214, and combiner cabinet 215 are sequentially arranged along the length of the container 211, with at least the DC-DC converter 214 located within the monitoring range of the monitoring component. The monitoring component can monitor the operating status of the DC-DC converter 214. For example, when the DC-DC converter 214 is operating, it tends to generate loud noise, potentially affecting the operation of other equipment. This noise may be caused by damage to electrical components. Therefore, monitoring the sound signals within the container 211 can serve as a basis for determining whether the DC-DC converter 214 is operating normally.

[0127] In some possible implementation schemes, a status indication component is provided on the DC-DC converter 214, and the monitoring component includes a video monitoring component, at least the status indication component is located within the field of view of the video monitoring component. The data on the status indication component can be collected through the video monitoring component, so that the working condition of the DC-DC converter 214 can be obtained. The status indication component includes any one or more of an instrument panel, a status light and a display screen. The instrument panel can display status data, the status light housing directly represents the corresponding information by color or flashing, and the display screen can also directly display some operating parameters of the DC-DC converter 214. For example, the status indication component can give visual signals corresponding to states such as overheating, leakage, electrical component burnout failure, unstable voltage output and short circuit of the DC-DC converter 214. A video monitoring component can simultaneously capture the status indication components on each DC-DC converter 214, thereby obtaining status data of all DC-DC converters 214.

[0128] The status indicator component is disposed on the top wall of the DC-DC converter 214 and / or on the peripheral side walls of the DC-DC converter 214. The status indicator component is disposed on the top wall of the DC-DC converter 214 without obstruction and is more easily captured by the video monitoring device.

[0129] The energy storage system 21 includes a plurality of DC-DC converters 214, each of which is located on both sides of the container 211 along the width direction. A channel a is formed between the DC-DC converters 214 located on both sides of the container 211 along the width direction. Figure 5 and Figure 13As shown, channel a facilitates navigation for personnel. A status indicator assembly is located on the sidewall of the container 211, facing channel a. This allows all DC-DC converters 214 to be concentrated on one side of channel a. The video acquisition terminal of the video monitoring device faces channel a, allowing simultaneous capture of the status indicator assemblies of all DC-DC converters 214. The arrangement of the DC-DC converters 214, channel a, and status indicator assembly allows a single video monitoring device to capture the status indicator assemblies of all DC-DC converters 214, simplifying the monitoring assembly structure.

[0130] In some possible implementations, see Figure 6 As shown, the container 211 is provided with a communication interface 2114122, which is electrically connected to the monitoring component. The communication interface 2114122 can be connected to the tractor 1 of the electric locomotive to send the data obtained by the monitoring component to the tractor 1 of the electric locomotive for easy viewing by staff.

[0136] In some possible implementation schemes, the movable portion 2192 is movable in a direction parallel to the width direction of the bottom frame 2111. In the use state, the movable portion 2192 extends out of the bottom frame 2111 along the width direction of the bottom frame 2111. In the storage state, the movable portion 2192 retracts to one side of the bottom frame 2111.

A plurality of lifting coordination mechanisms 219 can be provided on the bottom frame 2111, and each lifting coordination mechanism 219 is respectively provided on both sides of the bottom frame 2111 along the width direction. The lifting coordination mechanisms 219 on the same side of the bottom frame 2111 are provided sequentially along the length direction of the bottom frame 2111. By setting up multiple lifting cooperation mechanisms 219, the connection parts between the bottom frame 2111 and the lifting equipment can be increased, thereby improving the stability of the connection structure between the lifting equipment and the bottom frame 2111. In addition, the setting of multiple lifting cooperation mechanisms 219 is conducive to uniform force on the container 211, and the posture of the container 211 remains stable and is not easy to tilt.

[0137] In some possible embodiments, the bottom frame 2111 includes a plurality of structural beams 21111, each of the structural beams 21111 is arranged in sequence along the length direction of the bottom frame 2111, each of the structural beams 21111 extends along the width direction of the frame, and the fixing portion 2191 is located between each of the structural beams 21111 and is fixedly connected to the structural beams 21111.

[0138] Each lifting and cooperating mechanism 219 is disposed within the space formed between two adjacent structural beams 21111, without occupying additional space within the bottom frame 2111. This embodiment of the present application fully utilizes the bottom frame 2111, and the assembly structure of the lifting and cooperating mechanism 219 is adaptively designed based on the structural characteristics of the bottom frame 2111. The structural beams 21111 have high structural strength, and the fixing portion 2191 is directly connected to the structural beams 21111, resulting in high structural strength and a long service life for the lifting and cooperating mechanism 219.

[0139] In some possible embodiments, the bottom frame 2111 includes a plurality of connectors 21112, each of which is located between two adjacent structural beams 21111 and is welded to the two structural beams 21111 and the fixing portion 2191 located between the two structural beams 21111. The connectors 21112 are metal structures and can be metal plates or metal blocks. The connectors 21112 are welded to the structural beams 21111 on both sides and the fixing portion 2191 in the middle, connecting the three into an integrated structure.

[0140] Among them, when the fixing part 2191 is cylindrical, the connecting piece 21112 can be provided with a circular avoidance hole, the avoidance hole can be sleeved on the fixing part 2191, and the inner end surface of the avoidance hole is fitted and welded to the surface of the fixing part 2191.

The side main beams 21113 have through holes extending along the width direction of the bottom frame 2111, and the fixing portion 2191 is inserted into the through holes. The fixing portion 2191 can be a cylindrical body and has a chute extending in a direction perpendicular to the side main beams 21113. The chute defines the movable direction of the movable portion 2192.

[0142] In some possible implementations, the fixed portion 2191 has a through-groove, through which the movable portion 2192 is disposed. Flanges 21921 are provided at both ends of the movable portion 2192. The outer diameter of the flanges 21921 is larger than the inner diameter of the groove. The flanges 21921 at both ends of the movable portion 2192 limit the sliding range of the movable portion 2192, preventing the movable portion 2192 from sliding off the fixed portion 2191 as a whole.

[0143] In some possible embodiments, the movable portion 2192 is located on the flange portion 21921 on the outside of the bottom frame 2111 and has a connection hole. One end of the stopper can pass through the connection hole to connect to the fixed portion 2191 or the container 211, while the other end is retained on the flange portion 21921. The stopper may include a cap and a screw. The screw passes through the connection hole and is threadedly connected to a threaded groove provided on the fixed portion 2191 or the container 211. The cap is retained on the flange portion 21921, thereby fixing the position of the movable portion 2192 and preventing the movable portion 2192 from accidentally sliding out and colliding with external structures.

[0145] See also Figures 2 to 4 and Figure 7 As shown, an embodiment of the present application provides an energy storage system 21 that is convenient for overall assembly, including: a container 211, a battery pack 212, a high-voltage box 213, a DC-DC converter 214, and a junction box 215. The container 211 has a cavity and a locking mating portion 2115. The battery pack 212, the high-voltage box 213, the DC-DC converter 214, and the junction box 215 are all disposed in the cavity. The battery pack 212 is electrically connected to the high-voltage box 213, the high-voltage box 213 is electrically connected to the DC-DC converter 214, and the junction box 215 is electrically connected to the DC-DC converter 214. When the container 211 is configured to be supported on a support surface of a flat car 22 having a locking mechanism 221, the locking mating portion 2115 can lock and mate with the locking mechanism 221 to securely connect the container 211 to the flat car 22.

[0146] The energy storage system 21 of the present application can be quickly assembled and connected to the flat car 22 through the locking mating portion 2115 and the locking mechanism 221, significantly improving assembly efficiency. The container 211 can be pre-assembled and then directly hoisted to the support surface of the flat car 22 using a lifting device. The locking mating portion 2115 and the locking mechanism 221 are then manually locked together to complete the connection and fixation of the container 211 to the flat car 22.

[0147] In some possible embodiments, the container 211 has a skeleton, which encloses the cavity, and multiple locking fitting parts 2115 are arranged on the skeleton. The locking fitting parts 2115 have a locking cavity and a locking hole 21151 connected to the locking cavity. When the container 211 is supported on the supporting surface of the flat car 22, the locking mechanism 221 on the flat car 22 can be inserted into the locking hole 21151 to lock the container 211.

[0148] In this embodiment, the locking mechanism 221 partially protrudes from the flat support surface. When the container 211 is seated on the flat car 22, the position of the container 211 can be adjusted by the lifting equipment, so that each locking mechanism 221 can be smoothly inserted into the locking hole 21151 of the container 211, and the locking mechanism 221 limits the position of the container 211.

[0149] In some possible implementations, a lifting and coordinating mechanism 219 is provided on the container 211. The lifting and coordinating mechanism 219 can cooperate with the lifting equipment to lift or lower the container 211 so as to smoothly assemble the container 211 on the flat car 22, thereby avoiding manual handling and significantly improving assembly efficiency.

[0150] The storage vehicle 2 comprises a flat car 22 and the energy storage system 21 for easy assembly. The flat car 22 is provided with a locking mechanism 221. When the container 211 is supported on the flat car 22, the locking mechanism 221 can lock with the locking engagement portion 2115 on the energy storage system 21.

[0151] In some possible embodiments, the locking engagement portion 2115 has a locking cavity and a locking hole 21151 communicating with the locking cavity. The locking mechanism 221 includes a locking head 2211 having an upwardly convex guide surface in the middle. When the container 211 is supported on the flat car 22, the locking head 2211 can be inserted into the locking hole 21151. The upwardly convex guide surface is provided on the locking head 2211 and can be a structure with a pointed top and a thick bottom, so that it can be smoothly inserted into the locking hole 21151.

[0152] In some possible embodiments, the locking fitting portion 2115 has a bottom contact wall, on which the locking hole 21151 is arranged. When the container 211 is supported on the flat car 22, the contact wall of the bottom plate 217131 can fit into the supporting surface of the flat car 22, and the lock head 2211 can be smoothly inserted into the locking hole 21151.

[0153] See also Figure 4 and Figure 7 As shown, the locking hole 21151 can be an elongated hole, and the locking mechanism 221 includes a rotating shaft 2212 rotatably connected to the flat car 22, the locking head 2211 is connected to the rotating shaft 2212, and the length direction of the locking head 2211 is perpendicular to the rotating shaft 2212. When the container 211 is supported on the flat car 22 and the locking head 2211 is inserted into the locking hole, the locking head 2211 can rotate, for example, rotate ninety degrees, so that the extension direction of the locking head 2211 is perpendicular to the elongated hole to engage with the bottom contact wall. The width direction of the locking head 2211 is smaller than the elongated hole, so that it can be smoothly inserted into the elongated hole. The locking head 2211 is connected to the rotating shaft 2212, and the locking head 2211 and the rotating shaft 2212 can rotate so that the length direction of the locking head 2211 is perpendicular to the elongated hole. The locking head 2211 can be confined in the elongated hole and will not easily escape from the elongated hole.

[0154] In some possible embodiments, the locking portion 2115 is provided with a first opening 21152, which communicates with the locking cavity. The first opening 21152 allows an operator to observe whether the lock 2211 is properly rotated, thereby facilitating the operator's assembly and disassembly tasks. The first opening 21152 is large enough to allow a worker's hand or tool to pass through, allowing for smooth engagement with the lock 2211 and facilitating rotation of the lock 2211 to securely connect the flatcar 22 to the container 211.

[0155] In some possible implementation schemes, an operating cavity and an operating port 222 communicating with the operating cavity are provided on the flat cart 22 , and the rotating shaft 2212 partially extends to the operating cavity.

[0156] The worker can insert his palm into the operating cavity through the operating opening 222 and rotate the rotating shaft 2212 to adjust the position of the lock head 2211 so that the lock head 2211 is engaged with the locking fitting portion 2115 or is disengaged.

[0157] In some possible implementations, see Figure 4 As shown, the electric storage vehicle 2 includes a handle 2213, which is connected to the rotating shaft 2212 and is located in the operating cavity. The setting of the handle increases the torque and is convenient for the human hand to hold, so that the rotating shaft 2212 can be easily rotated, reducing the difficulty of operation.

[0158] Example 10

[0159] See also Figure 9 As shown, an embodiment of the present application provides an energy storage system 21 with good heat dissipation, comprising: a container 211, a battery pack 212 and a water cooling unit 216. The container 211 has a frame and a skin covering the frame. A plurality of accommodating cavities are formed in the container 211, each accommodating cavity including a battery accommodating cavity and a unit accommodating cavity. A ventilation portion connected to the unit accommodating cavity is provided on the skin (not shown). The battery pack 212 is disposed in the battery accommodating cavity. The water cooling unit 216 is disposed in the unit accommodating cavity, and the water cooling unit 216 is connected to the battery pack 212 via a water cooling pipe.

[0160] The energy storage system 21 provided in the embodiment of the present application can facilitate the smooth discharge of heat from the water cooling unit 216 by providing a ventilation portion on the skin, thereby ensuring the cooling effect of the water cooling unit 216 on the battery pack 212.

[0161] In some possible implementations, the water-cooling unit 216 has an air inlet 2161 and an air outlet 2162. The ventilation portion includes an air inlet grille area and an air outlet grille area provided on the skin. The air inlet grille area is connected to the air inlet 2161, and the air outlet grille area is connected to the air outlet 2162. A fan is provided on the water-cooling unit 216. When the fan is in operation, a negative pressure is formed on one side of the air inlet 2161, causing external air to enter the unit's accommodating cavity through the air inlet 2161, and then enter the air inlet 2161 and the water-cooling unit 216 for heat exchange before being discharged through the air outlet 2162 and the air outlet grille area.

[0162] In some possible implementation schemes, a partition is provided in the unit accommodating cavity, which divides the unit accommodating cavity into two sub-cavities, and the air inlet 2161 and the air outlet are respectively located in the two sub-cavities, and the air inlet grid area is connected to the sub-cavity with the air inlet 2161, and the air outlet grid area is connected to the sub-cavity with the air outlet.

[0163] The partition divides the sub-cavity into an air inlet cavity and an air outlet cavity, preventing the hot air discharged from the air outlet from directly entering the water cooling unit 216 through the air inlet 2161, ensuring the heat dissipation effect of the water cooling unit 216, and improving the cooling performance of the water cooling unit 216.

[0164] In some possible implementations, the energy storage system 21 with good heat dissipation includes a cluster frame 217, which is arranged inside the skeleton. The cluster frame 217 includes a plurality of longitudinal support frames 2171, each of which is arranged in sequence along the length of the container 211. Each of the longitudinal support frames 2171 is connected to the skeleton, and a plurality of horizontal support frames 2172 are arranged between two adjacent longitudinal support frames 2171. Each of the horizontal support frames 2172 is arranged in sequence along the longitudinal direction. The two ends of the horizontal support frame 2172 are respectively fixedly connected to the two adjacent longitudinal support frames 2171, and a receiving cavity is formed between the upper and lower adjacent horizontal support frames 2172. Among them, among the receiving cavities, some are battery receiving cavities, some are unit receiving cavities, and some are control component receiving cavities.

[0165] In some possible implementation schemes, an isolation layer is provided on the longitudinal support frame 2171 and the horizontal support frame 2172 that enclose the unit accommodating cavity, so that a closed cavity is formed in the unit accommodating cavity, and the flowing air in the water-cooling unit 216 will not enter other battery accommodating cavities and will not affect the normal operation of the surrounding battery packs 212.

[0166] In some possible implementations, a control component accommodating cavity is formed between some of the upper and lower adjacent horizontal support frames 2172 in the cluster frame 217, see Figure 9 and Figure 12 As shown, the energy storage system 21 includes a perfluorohexanone fire-fighting device 2110 and a high-voltage box 213. The perfluorohexanone fire-fighting device 2110 includes a liquid container and a gas pipeline 21102 connected to the liquid container. The liquid container and the high-voltage box 213 are both arranged in the control component accommodating chamber. The gas pipeline 21102 is respectively connected to each of the battery packs 212. The high-voltage box 213 is connected to the battery pack 212 via a power cable b. The high-voltage box 213 and the perfluorohexanone fire-fighting device 2110 are arranged in pairs in the same control component accommodating chamber, facilitating direct electrical connection between the two.

[0167] The cavities in the same row of cluster racks 217 can all be battery cavities, or the cavities in the same row can all be unit cavities and control component cavities. Battery packs 212 and water cooling units 216 are located in cavities in different rows. Water cooling units 216 and high-voltage boxes 213 are located in the same row of cavities.

[0168] In some possible implementations, see Figures 10 to 12 As shown, the energy storage system 21 with good heat dissipation includes a fixing frame 5 and a protective cover 6. The cluster frame 217 includes a vertical beam 21711. The fixing frame 5 is connected to the vertical beam 21711. The protective cover 6 is detachably connected to the fixing frame 5. A protective cavity is formed between the protective cover 6 and the fixing frame 5. The gas pipeline 21102 is provided with multiple three-way joints 211021. The three-way joints 211021 are connected to the bronchial tubes for connecting to the battery pack 212. The three-way joints 211021 are located within the protective cavity. The gas pipeline 21102 may include a main gas pipeline. Multiple three-way joints 211021 are provided along the extension path of the main gas pipeline. Each three-way joint 211021 is connected to a bronchial tube, and each bronchial tube is connected to a corresponding battery pack 212. The fixing frame 5 and the protective cover 6 serve to secure the three-way joints 211021.

[0169] In some possible implementations, the power cable b and the signal cable connected to the battery pack 212 can be connected and fixed to the protective cover 6. The power cable b and the signal cable can be connected to the protective cover 6 through a connector. The connector can be a cable tie or a ring, etc.

[0170] The protective cover 6 has multiple functions. It can not only fix the three-way joint 211021, but also be used to fix and limit the power cable b and the signal cable.

[0171] The fixing frame 5 may include two extension arms and a connecting arm connecting the two extension arms. A gap exists between the two extension arms, which are positioned on either side of the vertical beam 21711 and connected to the vertical beam 21711 via fasteners. The protective cover 6 may be connected to the connecting arms via fasteners, forming a protective cavity between the protective cover 6 and the connecting arms.

[0172] Example 11

[0173] See also Figures 9 to 12As shown, the embodiment of the present application provides a new type of energy storage system, which is a gas fire-fighting energy storage system 21, comprising: a container 211 and a perfluorohexanone fire-fighting device 2110. The container 211 has a cavity, in which a battery pack 212 and a high-voltage box 213 are arranged. The battery pack 212 is electrically connected to the high-voltage box 213. The perfluorohexanone fire-fighting device 2110 is arranged in the cavity. The perfluorohexanone fire-fighting device 2110 includes a liquid container and a gas pipeline 21102 connected to the liquid container. The gas pipeline 21102 is respectively connected to each of the battery packs 212. The perfluorohexanone fire-fighting device 2110 is used to control the conduction of the gas pipeline 21102 upon receiving a fire-fighting command to inject fire-fighting gas into the battery pack 212. The perfluorohexanone fire-fighting device 2110 provided in the embodiment of the present application can inject fire-fighting gas into the battery pack 212 when the battery pack 212 catches fire at high temperature, thereby achieving the effect of cooling and extinguishing the fire, thereby improving safety.

[0174] In some possible implementation schemes, a BMS is provided in the high-voltage box 213 , and the BMS is electrically connected to each of the battery packs 212 , and the BMS is electrically connected to the perfluorohexanone fire-fighting device 2110 , and is used to control the perfluorohexanone fire-fighting device 2110 to connect or cut off the gas pipeline 21102 .

[0175] Upon receiving a control command, the BMS can control the perfluorohexanone firefighting device 2110 to be turned on or off, automatically controlling the start and stop of firefighting operations. A temperature sensor can be installed within the battery pack 212 and electrically connected to the BMS within the high-voltage box 213. The temperature sensor transmits a detected temperature signal to the BMS. When the temperature detected by the temperature sensor exceeds a set value, the BMS triggers an opening command to the perfluorohexanone firefighting device 2110, thereby opening the gas pipeline 21102 of the perfluorohexanone firefighting device 2110 and injecting firefighting gas into the corresponding battery pack 212.

[0176] In some possible embodiments, the gas fire-fighting energy storage system 21 includes multiple perfluorohexanone fire-fighting devices 2110, each of which is connected to a corresponding number of battery packs 212 through a gas pipeline 21102, and each perfluorohexanone fire-fighting device 2110 is electrically connected to a corresponding high-voltage box 213.

[0177] The gas fire-fighting energy storage system 21 includes a cluster rack 217, which is located in the cavity and connected to the container 211. The cluster rack 217 forms a plurality of accommodating cavities in the container 211, and each battery pack 212 is respectively accommodated in a corresponding accommodating cavity. Each of the high-voltage boxes 213 and the liquid container of the perfluorohexanone fire-fighting device 2110 electrically connected thereto are arranged in the same accommodating cavity.

[0178] The electrically connected high-voltage box 213 and the perfluorohexanone fire-fighting device 2110 are respectively connected to the same number of battery packs 212. Therefore, when the BMS of a high-voltage box 213 receives a signal indicating a battery pack 212 failure, it can directly control the electrically connected perfluorohexanone fire-fighting device 2110 to open and inject fire-fighting gas into the corresponding faulty battery pack 212.

[0179] The gas fire-fighting energy storage system 21 includes multiple clusters of battery packs 212, and the battery packs 212 of each cluster are respectively arranged in each accommodating cavity in the same column on the cluster rack 217. The high-voltage box 213 and the perfluorohexanone fire-fighting device 2110, which are electrically connected to each other, are respectively connected to each battery pack 212 of the same cluster. When any battery pack 212 of the battery packs 212 of a certain cluster fails, the temperature signal detected by the temperature sensor in the battery pack 212 is transmitted to the BMS of the high-voltage box 213. When the BMS of the high-voltage box determines that the temperature is higher than the set value, it can directly control the gas pipeline 21102 of the corresponding perfluorohexanone fire-fighting device 2110 to be turned on, so as to inject fire-fighting gas into each battery pack 212 of the corresponding cluster at the same time, thereby improving the fire-fighting treatment effect and preventing the adjacent battery packs 212 from being ignited, causing the fire to escalate.

[0180] In some possible embodiments, the gas fire-fighting energy storage system 21 includes an external sensor, which is arranged in the cavity and located outside the battery pack 212. The external sensor is electrically connected to the perfluorohexanone fire-fighting device 2110, wherein the external sensor includes a smoke sensor and a temperature sensor.

[0181] The external sensor can be understood as a temperature sensor disposed within the cavity of the container 211, but not within the battery pack 212. The external sensor is used to detect smoke and / or temperature information. These external sensors can be directly electrically connected to the perfluorohexanone firefighting device 2110. When the perfluorohexanone firefighting device 2110 determines that the smoke and / or temperature information reaches a set value, it automatically controls the conduction of the gas pipeline 21102.

[0182] Container 211 comprises a skeleton and a skin, with a cluster frame 217 disposed within the skeleton. The cluster frame 217 comprises multiple longitudinal support frames 2171, spaced sequentially along the length of the container 211. An external sensor can be positioned within the inner cavity formed between each pair of adjacent longitudinal support frames 2171. When the external sensor detects an abnormal signal, it triggers the connection of the gas pipe 21102 of the perfluorohexanone firefighting device 2110 connected to the entire cluster of battery packs 212 within the inner cavity. It should be noted that each battery pack 212 in the same cluster is connected to the gas pipe 21102 of the same perfluorohexanone firefighting device 2110.

[0183] In some possible embodiments, the cluster frame 217 divides the cavity into multiple isolated spaces. These isolated spaces can be formed between two longitudinal support frames 2171. For example, by covering the longitudinal support frames 2171 with an isolation plate, an isolated space can be formed between two longitudinal support frames 2171 covered with isolation plates. Some of the isolated spaces contain cavities for accommodating the battery pack 212, while others contain cavities for accommodating the high-voltage box 213 and the perfluorohexanone firefighting device 2110. The external sensor is placed in at least the isolated space containing the battery pack 212.

[0184] Example 12

[0185] See also Figure 13 and Figure 14 As shown, an embodiment of the present application provides a new type of energy storage system, which is a water fire-fighting energy storage system 21, comprising: a container 211 and a fire-fighting water pipe 7. The container 211 has a cavity, in which a battery pack 212, a high-voltage box 213, a DC-DC converter 214, and a junction box 215 are arranged. The battery pack 212 is electrically connected to the high-voltage box 213, the high-voltage box 213 is electrically connected to the DC-DC converter 214, and the junction box 215 is electrically connected to the DC-DC converter 214. A fire-fighting water pipe 7 is connected to the container 211, the fire-fighting water pipe 7 is connected to the cavity, and the fire-fighting water pipe 7 is used to inject water into the cavity. The energy storage system 21 of the present application is provided with a fire-fighting water pipe 7, which can directly inject water into the cavity when heat loss and fire occur inside the energy storage system 21, and submerge the battery pack 212 with water, thereby achieving the purpose of cooling and extinguishing the fire.

[0186] In some possible implementations, the battery pack 212, high-voltage box 213, DC-DC converter 214, and combiner cabinet 215 are sequentially arranged along the length of the container 211. The fire hose 7 is at least partially located within the cavity and extends along the length of the container 211. The fire hose 7 is provided with multiple water outlets, each of which is sequentially arranged along the length of the fire hose 7. In the event of a fire in the energy storage system 21, the fire hose 7 can spray water at multiple locations along the entire length of the container 211, covering the entire cross-section of the container 211 and preventing the spread of fire.

[0187] In some possible implementation schemes, a number of longitudinal support frames 2171 are provided in the container 211, and each of the longitudinal support frames 2171 divides the cavity into multiple isolation spaces. The battery pack 212 is provided in the corresponding isolation space, the high-voltage box 213 is provided in the corresponding isolation space, the DC-DC converter 214 and the junction cabinet 215 are provided in the corresponding isolation space, and the fire water pipe 7 extends through each of the isolation spaces. The fire water pipe 7 is provided with a water outlet on the pipe section located in each of the isolation spaces.

[0188] It should be noted that the longitudinal support frame 2171 is a frame structure, and an isolation plate can be covered on the longitudinal support frame 2171, so that an isolation space can be formed between two longitudinal support frames 2171 covered with isolation plates.

[0189] The present application divides the cavity of container 211 into multiple isolated spaces, effectively preventing interference between components within the different isolated spaces and improving safety. The present application's fire hose 7, designed to address the structural characteristics of the isolated spaces within container 211, is arranged to pass through each of the isolated spaces in sequence, with outlets provided on each pipe section within each isolated space. This allows each isolated space to independently store water, meeting the requirements for flooding firefighting.

[0190] In some possible implementations, the section of the fire hose 7 located within the cavity is located on top of the battery pack 212, high-voltage box 213, DC-DC converter 214, and combiner cabinet 215. Fire spreads upward from the bottom, while fire hose is sprayed downward from the top, first reaching the upper structural components. This prevents the fire from spreading rapidly upward, resulting in a more effective firefighting operation.

[0191] In some possible embodiments, the container 211 includes a top frame 2112 and a bottom frame 2111. The cavity is formed between the top frame 2112 and the bottom frame 2111. The fire hose 7 is connected to the top frame 2112. The top frame 2112 is located on top of each battery pack 212, high-voltage box 213, DC-DC converter 214, and combiner cabinet 215. The fire hose 7 is connected to the top frame 2112 and can be located on top of the battery pack 212, high-voltage box 213, DC-DC converter 214, and combiner cabinet 215, reducing assembly difficulty and simplifying the installation structure of the fire hose 7.

[0192] Specifically, the water firefighting energy storage system 21 includes a connector, which is mounted on the firefighting water pipe 7 and connected to the top frame 2112. The connector can be a lifting ring or a clamp, which is mounted on the firefighting water pipe 7 and connected to the top frame 2112.

[0193] In some possible embodiments, the container 211 includes two end frames 2113, located at either end of the top frame 2112 and respectively connected to the top frame 2112 and the bottom frame 2111. One end of the fire hose 7 extends through the end frame 2113 to connect to a water source. The fire hose 7 extends to the end frame 2113. A large gap exists between the end frame 2113 of the current storage vehicle 2 and the end frame 2113 of another adjacent storage vehicle 2. This gap can accommodate an external water pipe, facilitating the connection of the fire hose 7 to a water source using the external water pipe.

[0194] In some possible embodiments, the fire hose 7 includes a main pipe section 71 and a lower extension pipe section 72, both of which are located within the cavity. The main pipe section 71 extends along the length of the container 211, and the lower extension pipe section 72 is adjacent to the end frame 2113. The top end of the lower extension pipe section 72 is connected to the main pipe section 71, and the bottom end of the lower extension pipe section 72 is connected to the water inlet pipe section 73, which passes through the end frame 2113 to connect to a water source.

[0195] Example 13

[0196] Embodiment 1 of the present application provides an energy storage system 21, comprising: a container 211, an energy storage assembly, and a control assembly. Container 211 has an energy storage chamber and a control chamber, the energy storage chamber and the control chamber being isolated from each other. A locking mating portion for connection and fixation is provided at the bottom of container 211. The energy storage assembly is disposed in the energy storage chamber and includes a battery pack 212, a high-voltage box 213, and a cooling unit. The battery pack 212 is electrically connected to the high-voltage box 213. The control assembly is disposed in the control chamber and includes a DC-DC converter 214 and a junction box 215. Both the DC-DC converter 214 and the junction box 215 are disposed in the control chamber. The high-voltage box 213 is electrically connected to the DC-DC converter 214, and the DC-DC converter 214 is electrically connected to the junction box 215. The energy storage system 21 of the present application divides the control assembly and the energy storage assembly into separate compartments, resulting in a more rational layout and significantly improved safety.

[0197] A cluster rack 217 may be provided in the container 211. The area where the cluster rack 217 is located may serve as the energy storage cavity, while the area not occupied by the cluster rack 217 in the container 211 serves as the control cavity. A partition or other structure may be provided on the side of the cluster rack 217 facing the control cavity to separate the energy storage cavity from the control cavity.

[0198] In some possible implementation schemes, the energy storage system 21 includes multiple DC-DC converters 214, each of the DC-DC converters 214 is electrically connected to a corresponding number of high-voltage boxes 213, each of the high-voltage boxes 213 is electrically connected to a corresponding number of battery packs 212, and each of the DC-DC converters 214 is electrically connected to the junction cabinet 215.

[0199] The energy storage system 21 of this application features a modular design. The electrically connected battery pack 212, high-voltage box 213, and DC-DC converter 214 form a subsystem. Energy storage system 21 has multiple subsystems. A failure in one subsystem does not affect the operation of other subsystems, thereby improving the stability of energy storage system 21 and preventing a single subsystem failure from causing the entire system to shut down. Each battery pack 212 in the same subsystem can utilize batteries from the same batch, resulting in minimal variation and excellent quality stability.

[0200] In some possible implementations, see Figure 13 As shown, the DC-DC converters 214 are arranged in two rows, forming a channel a between the two rows of DC-DC converters 214. The arrangement of channel a facilitates walking for workers to smoothly perform maintenance work on the DC-DC converters 214.

[0201] In some possible implementations, two rows of DC-DC converters 214 are located on either side of the control chamber along the width of the container 211, with the DC-DC converters 214 in each row arranged sequentially along the length of the container 211. A passage a formed between the two rows of DC-DC converters 214 extends along the length of the container 211, facilitating workers walking past each DC-DC converter 214 in sequence.

[0202] In some possible implementations, see Figure 13 As shown, the energy storage system 21 includes a door body. The container 211 is provided with a door opening 8, the door opening 8 communicating with the passage a. The door body is connected to the container 211 and is used to open or close the door opening 8. The door body provides a passage a for workers to enter and exit the container 211.

[0203] In some possible implementations, the container 211 is provided with side frames on both sides along the width direction, and the side frames are connected to the end frames. Each row of DC-DC converters 214 is close to the corresponding side frame, and each row of DC-DC converters 214 is arranged sequentially along the length of the corresponding side frame, and the door opening 8 is opened in the side frame. If the side frame is long, the door opening 8 can be opened at a position of the side frame row close to the end frame 2113 of the container 211.

[0204] In some possible implementations, see Figure 13As shown, the container 211 is provided with end frames 2113 at both ends along its length. The end frames 2113 connect the two side frames.

The combiner cabinet 215 is located at the end of one of the rows of DC-DC converters 214, and its location also makes it convenient for workers to approach and perform maintenance tasks.

The traction vehicle 1 has an electric running mechanism and a control device electrically connected to the electric running mechanism. The control device is used to control the running of the electric running mechanism. The control device may include a computer board and an operating component arranged in the interior of the traction vehicle 1, etc. The battery storage vehicle 2 is connected to the traction vehicle 1 through a traction device 4. A DC-DC converter 214 and a plurality of battery packs 212 are provided on the battery storage vehicle 2. The battery pack 212 is electrically connected to the DC-DC converter 214. The DC-DC converter 214 is electrically connected to the electric running mechanism to provide driving power for the electric running mechanism. The present application provides a new type of electric locomotive, whose traction vehicle 1 can be directly powered by the battery storage vehicle 2. There is no need to set a pantograph on the electric locomotive, nor is there a need to set up a contact network for the electric locomotive to cooperate with the pantograph, thereby reducing operating costs.

[0208] In some possible implementation schemes, a cluster rack 217 is provided on the battery storage vehicle 2, and a plurality of accommodating cavities are formed on the cluster rack 217.

[0210] In some possible implementation schemes, the battery storage vehicle 2 is also provided with a junction cabinet 215 and a power electrical interface 2114111. The junction cabinet 215 is located on the side of the DC-DC converter 214 away from the cluster frame 217. Each of the DC-DC converters 214 is electrically connected to the input end of the junction cabinet 215. The output end of the junction cabinet 215 is electrically connected to the power electrical interface 2114111. The power electrical interface 2114111 is electrically connected to the electric walking mechanism of the tractor 1 to provide traveling power for the tractor 1.

[0211] In some possible implementation schemes, the new electric locomotive includes a plurality of the aforementioned battery storage vehicles 2, each of which is arranged in sequence, and adjacent battery storage vehicles 2 are connected through a traction device 4. The traction vehicle 1 is also provided with a power electrical interface 2114111 connected to the electric running mechanism, and the power electrical interfaces 2114111 of the traction vehicle 1 and the two adjacent ones of the aforementioned battery storage vehicles 2 are electrically connected.

[0212] The power connection port on the tractor 1 and the power connection port on the battery storage vehicle 2 can be directly connected by a cable. The length of the cable is greater than the length of the traction device 4. During driving, the cable will not be stretched and separated from the power connection port.

[0213] In some possible implementations, the battery storage vehicle 2 is provided with an auxiliary power interface 2114121, which is electrically connected to the combiner cabinet 215. The tractor 1 is provided with a battery, to which the auxiliary power interface 2114121 is electrically connected. The battery can be used to provide negative electricity to the battery storage vehicle 2. Even if the battery storage vehicle 2 is low on electricity, the battery can still power the control module, fire protection module, and water cooling unit 216 within the battery storage vehicle 2, allowing the battery storage vehicle 2 to operate normally.

[0214] In some possible implementations, both the tractor 1 and the battery storage vehicle 2 are provided with a communication interface 2114122.

[0215] In some possible implementations, the new electric locomotive includes a utility vehicle 3 connected to the battery storage vehicle 2 via a traction device 4. The utility vehicle 3 is used to carry cargo or passengers. The tractor 1 is positioned at the front, the battery storage vehicle 2 is in the middle, and the utility vehicle 3 is located at the rear, facilitating the cable connection between the battery storage vehicle 2 and the tractor 1.

[0217] The battery storage vehicle 2 has a cavity within which the DC-DC converter 214, battery pack 212, high-voltage box 213, and combiner cabinet 215 are housed. This prevents the battery pack 212, high-voltage box 213, DC-DC converter 214, and combiner cabinet 215 from being exposed to the outside world. A fire hose 7 is provided on the battery storage vehicle 2, extending into the cavity.

[0218] Example 15

[0219] See also Figure 1 As shown, an embodiment of the present application provides an electric locomotive comprising: a tractor 1, several battery storage vehicles 2, and multiple functional vehicles 3. The tractor 1 has an electric running mechanism that provides propulsion power for the tractor 1. The electric running mechanism may include rail wheels supported on rails. When the electric running mechanism is energized, the rail wheels can travel along the rails. Each battery storage vehicle 2 and each functional vehicle 3 are arranged in sequence, and adjacent ones of the tractor 1, each battery storage vehicle 2, and each functional vehicle 3 are detachably connected. The battery storage vehicle 2 has an energy storage system 21 that is electrically connected to the electric running mechanism and stores electrical energy to power the electric running mechanism. The functional vehicle 3 can be a transport vehicle for transferring goods or a carriage for passengers. Both the battery storage vehicle 2 and the functional vehicle 3 are unpowered vehicles, both having rail wheels and requiring active traction from the tractor 1 to travel along the rails.

[0220] In some possible implementation schemes, each of the battery storage vehicle 2 and the functional vehicle 3 is arranged in any of the following ways:

[0221] The first arrangement: The battery storage vehicle 2 is positioned between the tractor 1 and each functional vehicle 3. This closer proximity between the battery storage vehicle 2 and the tractor 1 facilitates its connection to the tractor 1 via cables. The number of battery storage vehicles 2 is not limited to one; rather, each battery storage vehicle 2 and each functional vehicle 3 can be centrally located, facilitating unified management.

[0222] The second arrangement mode: each storage vehicle 2 is arranged at the end of each functional vehicle 3 away from the traction vehicle 1, that is, each storage vehicle 2 is arranged at the rear of the electric locomotive. The storage vehicles 2 and the functional vehicles 3 are centrally arranged, thereby facilitating unified management.

[0223] The third arrangement: Each storage vehicle 2 is placed between the functional vehicles 3. That is, a functional vehicle 3 is placed on either side of each storage vehicle 2. The positions of the storage vehicles 2 are arranged according to actual needs. For example, a storage vehicle 2 can directly power an adjacent functional vehicle 3, thus facilitating cable routing.

[0224] The energy storage system 21 of each storage vehicle 2 has a power supply interface 2114111. Along the length of the electric locomotive, the power supply interfaces 2114111 of two adjacent storage vehicles 2 are electrically connected. By providing the power supply interfaces 2114111, it is convenient to electrically connect the storage vehicles 2 arranged in sequence to supply power to the tractor 1.

[0225] In some possible implementations, power supply interfaces 2114111 are provided at both ends of the battery storage vehicle 2 along its length. Of two adjacent battery storage vehicles 2, the power supply interface 2114111 at the rear of the front battery storage vehicle 2 is electrically connected to the power supply interface 2114111 at the front of the rear battery storage vehicle 2. Providing power supply interfaces 2114111 at both ends of the battery storage vehicle 2 facilitates the electrical connection of the current battery storage vehicle 2 to the adjacent battery storage vehicles 2 at both ends, thereby connecting each battery storage vehicle 2 to the power supply circuit of the tractor 1.

[0226] In some possible implementation schemes, the electric locomotive includes a workshop cable, with quick-connect plugs provided at both ends of the workshop cable. The workshop cable is located between two power storage vehicles 2, and the two ends of the workshop cable are electrically connected to the power electrical interfaces 2114111 of the two adjacent power storage vehicles 2.

[0227] The workshop cable is a flexible cable that connects two adjacent storage vehicles 2. The length of the workshop cable is greater than the distance between the two adjacent storage vehicles 2. In other words, the length of the workshop cable is greater than the length of the mechanical traction device 4 connecting the two adjacent storage vehicles 2, thereby preventing the workshop cable from detaching from the power supply interface 2114111 on the storage vehicle 2. It should be noted that the tractor 1 can also be provided with a power supply interface 2114111, which is electrically connected to the electric travel mechanism. The power supply interface 2114111 on the tractor 1 is electrically connected to the power supply interface 2114111 on the adjacent storage vehicle 2.

[0228] A large number of battery packs 212 are provided on the electric storage vehicle 2 , and the power electrical interfaces 2114111 are electrically connected to the battery packs 212 for integrating the battery packs 212 into the power supply circuit of the tractor 1 .

[0229] In some possible implementation schemes, a functional vehicle 3 is arranged between two adjacent battery storage vehicles 2, and an in-vehicle cable is arranged in the functional vehicle 3 located between the two battery storage vehicles 2, and both ends of the in-vehicle cable are electrically connected to the power electrical interfaces 2114111 of the two battery storage vehicles 2 at both ends of the functional vehicle 3.

[0230] When the battery storage vehicles 2 are arranged on both sides of the functional vehicle 3, it is necessary to set up in-vehicle cables on the functional vehicle 3 to electrically connect the two battery storage vehicles 2 at both ends of the functional vehicle 3, so that these battery storage vehicles 2 can be smoothly incorporated into the power supply circuit of the traction vehicle 1 to supply power to the electric walking mechanism.

[0231] The functional vehicle 3 located between the two battery storage vehicles 2 is provided with power connection ports at both ends. The two ends of the in-vehicle cable are connected to the two power connection ports, which are then electrically connected to the power supply ports 2114111 of the two battery storage vehicles 2 at both ends of the functional vehicle 3. When a functional vehicle 3 is provided with battery storage vehicles 2 at both ends, power connection ports are required at both ends of the functional vehicle 3 to electrically connect the two battery storage vehicles 2 spaced apart to jointly power the electric travel mechanism.

[0232] In some possible implementation schemes, the energy storage system 21 includes a container 211 and a plurality of battery packs 212, and each of the battery packs 212 is installed on the container 211 in multiple rows and columns. The battery packs 212 are electrically connected to the electric traveling mechanism. The energy storage system 21 on the same electric storage vehicle 2 needs to be equipped with a large number of battery packs 212, and these battery packs 212 are used to meet the travel requirements of the tractor 1. These battery packs 212 need to at least meet the electrical energy required for the travel of the electric traveling mechanism of the tractor 1. In order to arrange enough battery packs 212, the present application provides a container 211 structure to facilitate the reasonable layout of each battery pack 212.

[0233] In some possible implementations, the energy storage system 21 includes a high-voltage box 213, a DC-DC converter 214, and a combiner cabinet 215. The high-voltage box 213, the DC-DC converter 214, and the combiner cabinet 215 are all disposed in the container 211, and the high-voltage box 213, the DC-DC converter 214, and the combiner cabinet 215 are sequentially disposed along the length of the electric storage vehicle 2. The high-voltage box 213 is electrically connected to the battery pack 212, the DC-DC converter 214 is electrically connected to the high-voltage box 213, the combiner cabinet 215 is electrically connected to the DC-DC converter 214, and the combiner cabinet 215 is electrically connected to the electric travel mechanism. The energy storage system 21 includes not only battery packs 212 but also DC-DC converters 214 for voltage regulation. These are ultimately connected to a combiner cabinet 215, which connects the voltage outputs of the connected battery packs 212 in parallel or by shunting them to improve the stability, reliability, and safety of each battery pack 212. Each battery storage vehicle 2 constitutes an independent power supply unit, and the number of battery storage vehicles 2 can be selected based on actual needs to meet the range requirements of the electric locomotive.

[0234] In some possible implementation schemes, a lifting cooperation mechanism 219 is provided on the container 211, and the lifting equipment can lift the energy storage system 21 through the lifting cooperation mechanism 219, which facilitates the assembly and disassembly of the container 211 of the energy storage vehicle 2, facilitates the assembly of the energy storage vehicle 2, and improves the assembly efficiency of the energy storage vehicle 2.
