[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In view of the high cost of existing large-scale energy storage systems, an embodiment of the present invention provides a clustered energy storage system. By sharing a controller, an air-conditioning host, a fire-fighting host, and a PCS for multiple battery compartments in a battery compartment module, shared charging and discharging management, shared air-conditioning management, and shared fire-fighting management for multiple battery compartments are achieved, thereby reducing the cost of the energy storage system, improving the assembly and debugging efficiency of the energy storage system, and having good practical value.

[0025] To facilitate understanding of this embodiment, the embodiment of the present invention is described in detail below.

[0026] The embodiment of the present invention provides a cluster energy storage system, such as Figure 1 As shown, the cluster energy storage system 1 includes a control module 10, a battery compartment module 20 and an intelligent box transformer module 30 which are connected in sequence; the control module 10 is also connected to the intelligent box transformer module 30; wherein the intelligent box transformer module 30 includes a PCS (Power Conversion System, energy storage inverter) 31; the control module 10 includes a controller 11, an air conditioning host 12 and a fire host 13; the battery compartment module 20 includes a plurality of parallel battery compartments 21; each battery compartment 21 also includes a battery module 211 and a detection unit 212, and a BMS (Battery Management System, battery management system) 213 connected to the battery module 211.

[0027] It should be noted that the BMS 213 of each battery compartment 21 is also connected to the controller 11, and the detection unit 212 is connected to the air conditioning host 12 and the fire host 13. Figure 1The detection unit 212 includes a variety of detection devices, such as a temperature sensor, a humidity sensor, a combustible gas sensor, and a smoke sensor. The specific detection device can be set according to the actual situation, and the embodiment of the present invention does not limit this.

[0028] In actual applications, the controller 11 is used to obtain the battery parameters of the battery module 211 collected by BMS213, and generate a first control instruction according to the battery parameters; and send the first control instruction to PCS31, so that PCS31 manages the charge and discharge of the battery module 211 according to the first control instruction; specifically, BMS213 can collect the battery information of the battery module 211 in real time, where the battery information includes but is not limited to voltage, current, charging time, discharging time, temperature, SOC (State of Charge, battery remaining power percentage) and SOH (State of Health, battery health), etc., which can be set according to actual conditions, and the battery information is fed back to the controller 11, so that the controller 11 generates a first control instruction corresponding to the battery module 211 according to the battery information, and manages the charge and discharge of the battery module 211 through PCS31, so that the battery modules in multiple battery compartments, by sharing the controller, not only reduce the cost of each battery compartment, but also realize shared charge and discharge management of multiple battery modules, thereby improving the efficiency of charge and discharge management.

[0029] The air conditioning host 12 is used to obtain the first detection information of the battery compartment 21 collected by the detection unit 212, generate an air conditioning control instruction based on the first detection information, and send the air conditioning control instruction to the battery compartment 21 to manage the environment in the battery compartment 21; wherein the first detection information includes temperature information and / or humidity information; specifically, the detection unit collects the temperature information and humidity information of the environment where the battery module in the battery compartment is located through the temperature sensor and the humidity sensor, and feeds the temperature information and humidity information back to the air conditioning host, so that the air conditioning host generates an air conditioning control instruction based on the temperature information and humidity information to manage the environment in the battery compartment (i.e., the environment where the battery module is located), such as cooling, heating or dehumidifying the battery compartment. It should be noted that the first detection information may include only temperature information, only humidity information, or both temperature information and humidity information, which can be set according to actual conditions, and the embodiment of the present invention does not limit this.

[0030] The fire host 13 is used to obtain the second detection information of the battery compartment 21 collected by the detection unit 212, generate a fire control instruction according to the second detection information, and send the fire control instruction to the battery compartment 21 to manage the environment in the battery compartment 21; wherein the second detection information includes temperature information and / or smoke information and / or gas information. Specifically, the detection unit collects the temperature information, smoke information and gas information (i.e., combustible gas information) of the environment in which the battery module in the battery compartment is located through the temperature sensor, smoke sensor and combustible gas sensor, and feeds the temperature information, smoke information and gas information back to the fire host, so that the fire host generates a fire control instruction according to the temperature information, smoke information and gas information to manage the environment in the battery compartment (i.e., the environment in which the battery module is located), such as fire extinguishing the battery compartment. It should be noted that if the second detection information only includes one kind of information, such as smoke information, then the fire control instruction is an alarm instruction, so that the staff can manually check the battery compartment according to the alarm instruction. If the second detection information includes two or more kinds of information, then the fire control instruction is a fire extinguishing instruction, and the battery compartment is extinguished.

[0031] In particular, the fire protection host and the air-conditioning host can manage the environment of the same battery compartment at the same time, or can manage the environment of different battery compartments separately at the same time, or only the air-conditioning host can manage the environment of multiple battery compartments, etc. The specific settings can be made according to actual conditions, and the embodiments of the present invention do not limit this.

[0032] The above-mentioned cluster energy storage system realizes shared charging and discharging management, shared air conditioning management and shared fire protection management of multiple battery compartments through the shared controller, air conditioning host, fire protection host and PCS of multiple battery compartments in the battery compartment module, reduces the cost of the energy storage system, improves the assembly and debugging efficiency of the energy storage system, and has good practical value.

[0033] Optionally, each battery compartment also includes an air-conditioning indoor unit (not shown); in actual applications, the air-conditioning host is also used to send air-conditioning control instructions to the air-conditioning indoor unit of the battery compartment, so that the air-conditioning indoor unit manages the environment in the battery compartment according to the air-conditioning control instructions. Specifically, since the environment of each battery compartment may be different, the air-conditioning host generates corresponding air-conditioning control instructions based on the first detection information collected by the detection unit in each battery compartment, and sends the air-conditioning control instructions to the corresponding air-conditioning indoor units, so as to achieve environmental management of the corresponding battery compartment through the air-conditioning indoor units, that is, the air-conditioning host sends corresponding air-conditioning control instructions to each air-conditioning indoor unit, and the shared air-conditioning host manages the environment of each battery compartment. Compared with the existing air-conditioning system configured for each battery compartment, it not only improves the efficiency of battery compartment environmental management and the temperature control effect of the battery compartment, but also reduces the overall temperature control energy consumption of the entire cluster energy storage system, and reduces the cost and floor space of each battery compartment, thereby reducing the cost of the cluster energy storage system.

[0034] Optionally, each battery compartment also includes a fire fighting internal machine (not shown); in actual applications, the fire fighting host is also used to send fire fighting control instructions to the fire fighting internal machine of the battery compartment, so that the fire fighting internal machine manages the environment in the battery compartment according to the fire fighting control instructions. Specifically, since the environment of each battery compartment may be different, the fire fighting host generates corresponding fire fighting control instructions according to the second detection information collected by the detection unit in each battery compartment, and sends the fire fighting control instructions to the corresponding fire fighting internal machine respectively, so as to realize the environmental management of the corresponding battery compartment through the fire fighting internal machine, that is, the fire fighting host sends corresponding fire fighting control instructions to each fire fighting internal machine, and the shared fire fighting host manages the environment of each battery compartment. Compared with the existing fire fighting system configured for each battery compartment separately, since each fire fighting internal machine does not contain fire fighting gas, only fire fighting gas is contained in the fire fighting host, thereby reducing the fire fighting gas content of the entire cluster energy storage system. At the same time, for a single battery compartment, the content of available fire fighting gas is increased, and the fire fighting effect of each battery compartment is ensured on the basis of reducing the overall fire fighting cost of the energy storage system.

[0035] Optionally, the battery compartment module further includes a DC busbar (not shown) connected to a plurality of battery compartments; the DC busbar is used to connect the battery modules of the plurality of battery compartments in parallel and output busbar information to the PCS, so that the PCS can manage the charge and discharge of the battery modules of the plurality of battery compartments according to the busbar information; wherein the busbar information includes busbar current and / or busbar voltage. Specifically, the DC busbar outputs the busbar information to the PCS, and combines it with the control instruction information sent from the controller, so as to better manage the charge and discharge of the battery modules.

[0036] Optionally, the PCS includes a control unit and a DC / AC bidirectional converter; wherein the DC / AC bidirectional converter is connected to a plurality of battery compartments; in practical applications, the control unit is used to obtain a first control instruction, and trigger the DC / AC bidirectional converter according to the first control instruction to manage the charge and discharge of the battery modules of the plurality of battery compartments according to the corresponding working mode; wherein the working mode includes a charging mode and a discharging mode. Specifically, the DC / AC bidirectional converter is connected to the plurality of battery compartments through a switching circuit; wherein the input end of the switching circuit is connected to the DC / AC bidirectional converter, and the output end includes a plurality of interfaces, each of which is connected to the battery modules of the battery compartment, that is, the switching circuit is equivalent to a one-to-many switching circuit, and different interfaces are connected through the input port to realize the connection of the DC / AC bidirectional converter with different battery modules, so that the connected battery modules can be managed for charge and discharge, that is, multiple battery modules share a PCS, which reduces the cost of the cluster storage system compared to each battery module being configured with a PCS, and improves the charging and discharging management efficiency of the battery modules.

[0037] Furthermore, the above-mentioned intelligent box transformer module also includes an isolation transformer; wherein the isolation transformer includes a first switch and a second switch; specifically, the isolation transformer is connected to the DC / AC bidirectional converter through the first switch, and is connected to the external power grid through the second switch, thereby realizing the connection between the energy storage system and the external power grid, such as realizing the connection between the external power grid 380KV and the energy storage system 10KV. In addition, in practical applications, the above-mentioned PCS can also realize the bidirectional flow of electric energy. For example, when the battery module is in a charging state, the PCS can be used as a rectifier to convert the AC power in the external power grid into DC power and store it; when the battery module is in a discharging state, the PCS can be used as an inverter to convert the electric energy in the battery module from DC power to AC power and output it, thereby realizing the function of the energy storage system.

[0038] Further, such as Figure 2 As shown, the control module 10 further includes a power supply module 14 connected to the controller 11; the power supply module 14 is used to supply power to a plurality of battery compartments connected in parallel. The power supply module 14 is preferably a UPS (Uninterrupted Power Supply), and supplies power to each battery compartment through a low-voltage power supply to ensure the normal operation of the detection unit, the fire indoor unit, and the air conditioning indoor unit in the battery compartment.

[0039] Based on the above embodiments, the present invention also provides another cluster energy storage system, such as Figure 3As shown, the control module 10 includes a controller 11, an air-conditioning host 12, a fire-fighting host 13 and a power supply module 14, wherein the power supply module is connected to the controller 11, and the controller 11, the air-conditioning host 12, the fire-fighting host 13 and the power supply module 14 are respectively connected to each battery compartment 21 in the battery compartment module 20, and the multiple battery compartments are also connected to the intelligent box transformer module 30, and the intelligent box transformer module 30 is also connected to the external power grid, thereby realizing shared charging and discharging management, shared air-conditioning management and shared fire-fighting management of multiple battery compartments, which not only ensures the charging and discharging efficiency, temperature control effect and fire-fighting effect of the energy storage system, but also reduces the cost and floor space of the energy storage system, and has good practical value.

[0040] For ease of understanding, a 20MWH cluster energy storage system is used as an example. Figure 4 As shown, the battery compartment module 20 includes 10 2MWH battery compartments, wherein the 10 battery compartments share a control module 10, that is, a controller 11, an air conditioning host 12, a fire fighting host 13 and a power supply module 14, and a smart box transformer module 30, where the smart box transformer module 30 is a 5MW inverter booster compartment. It has been verified that since each battery compartment only contains an air conditioning indoor unit and a fire fighting indoor unit, there is no need to configure the air conditioning host and the fire fighting host separately, and the fire fighting indoor unit does not contain fire fighting gas, the capacity density of the battery compartment can be increased by at least 20%, the floor space of the battery compartment can be reduced by 30% to 40%, the power cable can be saved by 20% to 30%, and since multiple battery compartments are connected in parallel, the conversion efficiency of the energy storage system can be increased by 1% to 2%. In addition, multiple battery compartments share one air-conditioning host. Each battery compartment has a distributed temperature control unit with an air-conditioning unit installed inside, which can improve the cooling efficiency by 20% to 30%, while reducing the UPS backup power cost of the energy storage system; multiple battery compartments share one power supply module, such as a UPS low-voltage power supply system. Compared with each battery compartment being equipped with a UPS low-voltage power supply system, the efficiency can be improved by 5% or more; multiple battery compartments share one fire-fighting host and fire-fighting gas, which can reduce the fire-fighting gas by more than 50%, and the available fire-fighting gas of a single battery compartment is increased by 3 to 5 times. In addition, the operation and maintenance are centralized, which is convenient for equipment management and maintenance; multiple battery compartments share one DC junction cabinet, etc., which further reduces the cost of the energy storage system, improves the assembly and debugging efficiency of the energy storage system, and has good practical value.
