Description

Technical Field

[0001] This utility model relates to the field of energy storage power station technology, and in particular to an energy storage module and a containerized hybrid power station. Background Technology

[0002] Existing technology, such as patent publication number CN221408190U, discloses a containerized hybrid power station, including a container body, a diesel generator set, a battery pack, an energy storage converter, a water chiller, and a panel assembly. The container body includes a base, a first side plate, a second side plate, a third side plate, a fourth side plate, a partition, and a top plate. The first side plate, the second side plate, the third side plate, the fourth side plate, the partition, and the top plate are all disposed on the base. The partition divides the container body into a first accommodating space and a second accommodating space. The diesel generator set is disposed in the first accommodating space, and the battery pack, the energy storage converter, and the water chiller are disposed in the second accommodating space. The panel assembly is disposed opposite to the second accommodating space.

[0003] The existing technology has the following problems:

[0004] Existing containerized hybrid power stations have reserved a lot of maintenance space, resulting in low space utilization. They only have two battery modules, and the distance between the control cabinet and the battery modules is far, leading to small battery capacity, excessively long wiring, and low space utilization in hybrid power stations.

[0005] The above statements are for the purpose of providing background information in relation to this application only and do not necessarily constitute prior art. Utility Model Content

[0006] In view of the above problems, this application provides an energy storage module and a containerized hybrid power station to solve the technical problems of small battery capacity and low space utilization in existing hybrid power stations.

[0007] To achieve the above objectives, in a first aspect, this application provides an energy storage module, comprising:

[0008] The enclosure contains a first mounting bracket and a second mounting bracket, which are arranged opposite to each other. The first mounting bracket has a circuit breaker cabinet and an energy storage converter mounted on it, with the circuit breaker cabinet positioned above the energy storage converter. The second mounting bracket has two or more battery modules, a high-voltage box, and a chiller mounted on it. The two or more battery modules are arranged vertically on the second mounting bracket. The high-voltage box and the chiller are positioned above the battery modules, with the high-voltage box positioned to one side of the chiller.

[0009] Unlike existing technologies, the technical solution of this application features a first mounting bracket and a second mounting bracket within the enclosure, with the first and second mounting brackets positioned opposite each other. The first mounting bracket houses a circuit breaker cabinet and an energy storage converter, with the circuit breaker cabinet positioned above the energy storage converter. The second mounting bracket houses two or more battery modules, a high-voltage box, and a chiller. The two or more battery modules are arranged vertically on the second mounting bracket, with the high-voltage box positioned above the battery modules and to one side of the chiller. Thus, by mounting the circuit breaker cabinet and energy storage converter on the first mounting bracket, and the battery modules, high-voltage box, and chiller on the second mounting bracket, more battery modules can be mounted on the second mounting bracket. This utilizes the maintenance space for the second mounting bracket, resulting in a larger battery capacity and higher space utilization.

[0010] In one embodiment of this utility model, the housing includes a first accommodating space, the first mounting bracket is disposed on the left side of the first accommodating space, the second mounting bracket is disposed on the right side of the first accommodating space, and a maintenance passage is provided between the first mounting bracket and the second mounting bracket.

[0011] Thus, a maintenance channel is provided between the first and second mounting brackets, making wiring convenient and maintenance easy.

[0012] In one embodiment of this utility model, the box body includes a partition, a first side plate, a second side plate, and a third side plate. The two ends of the partition are respectively connected to the first side plate and the third side plate, and the two ends of the second side plate are respectively connected to the first side plate and the third side plate. The partition and the second side plate are parallel to each other, and the first side plate and the third side plate are parallel to each other.

[0013] This makes it convenient to install the first mounting bracket and the second mounting bracket between the partition, the first side plate, the second side plate, and the third side plate.

[0014] In one embodiment of this utility model, the left side of the first mounting bracket is disposed near the first side plate, and the front side of the first mounting bracket is disposed near the second side plate. The energy storage module also includes an operation panel, which is electrically connected to the circuit breaker cabinet and is disposed on the first side plate or the second side plate.

[0015] In this way, the operation panel is placed close to the circuit breaker cabinet, which solves the problem of excessively long wiring caused by the distance between the control cabinet and the battery module in the existing technology. The battery module is electrically connected to the energy storage converter and the circuit breaker cabinet, and the operation panel is placed on one side of the energy storage converter and the circuit breaker cabinet. The circuit breaker cabinet is closer to the operation panel, and the wiring is shorter.

[0016] In one embodiment of this utility model, the right side of the second mounting bracket is located near the third side plate, the front side of the second mounting bracket is located near the second side plate, the high-voltage box and the chiller are located on the top of the second mounting bracket, and the battery module is installed on both sides of the second mounting bracket below the chiller.

[0017] In this way, the first and second mounting brackets make good use of the space in the first accommodating space. The second mounting bracket has battery modules installed below the chiller, which allows for more battery modules to be installed, resulting in more batteries and higher space utilization.

[0018] In one embodiment of this utility model, five battery modules are mounted on the second mounting bracket, and the five battery modules are arranged vertically.

[0019] In this way, five battery modules can be installed on the second mounting bracket, which is three more than the existing ones.

[0020] In one embodiment of this utility model, an exhaust vent is provided on the third side plate, and the exhaust vent is positioned relative to the chiller.

[0021] In this way, the exhaust vents facilitate heat dissipation for the chiller.

[0022] In one embodiment of this utility model, the energy storage module further includes a fire-fighting module, which is installed on the housing and positioned above the high-pressure box and the chiller.

[0023] In this way, the fire protection module can play a role in fire detection, alarm notification, and coordinated fire suppression, thereby improving the safety of the energy storage module.

[0024] In one embodiment of this utility model, the energy storage module further includes a DC-DC converter, which is disposed on the front side of the first mounting bracket and is positioned relative to the battery module.

[0025] Thus, a DC-to-DC converter can transform voltage, stabilize output voltage, and improve power supply efficiency.

[0026] To achieve the above objectives, in a second aspect, this application provides a containerized hybrid power plant, including an energy storage module as described in any of the preceding claims.

[0027] Unlike existing technologies, the technical solution of this application installs the circuit breaker cabinet and energy storage converter on the first mounting bracket, and the battery module, high voltage box and chiller on the second mounting bracket. More battery modules can be installed on the second mounting bracket, which utilizes the maintenance space to place the second mounting bracket, resulting in a larger battery capacity and higher space utilization.
