[0001] This invention relates to the field of energy storage power station technology, and in particular to a temperature control system for a hybrid power station and a hybrid power station. Background Technology

[0002] To solve the problem of emergency power supply, the technical solution of integrated diesel and storage equipment is generally adopted. Existing integrated diesel and storage equipment is all in the form of containerized power stations.

[0003] More information related to the above technical solutions can be found in the following documents:

[0004] Patent CN114076027A discloses a containerized power station, which includes: a container body, the container body being divided into an electrical equipment compartment and a generator set compartment, with a louver on each side of the generator set compartment; a diesel generator set, which is located in the generator set compartment, the generator set compartment being equipped with an exhaust assembly, the exhaust assembly including a first air outlet, a water cooler and a cooling fan, the first air outlet being located at the top of the container body, the water cooler being located in the air outlet direction of the cooling fan; and an electrical equipment assembly, which is located in the electrical equipment compartment, the electrical equipment compartment including an air conditioning unit, the electrical equipment assembly being connected to the air conditioning unit through a second air inlet, and the second air outlet being connected to the outside of the container body.

[0005] Patent publication number CN217349191U discloses an energy storage container, comprising: a container body with a first and a second separately separated housing space; an energy storage battery disposed within the first housing space; and a control device including a control component and an operating component located within the second housing space. The control component is electrically connected to the energy storage battery, and the operating component partially extends through the outer surface of the container body and is electrically connected to the control component to control the charging and discharging of the energy storage battery. The energy storage battery container also includes a heat exchange device disposed on the container body, with a portion of the heat exchange device located within the first housing space and a portion extending beyond the container body. The heat exchange device regulates the temperature within the first housing space. The heat exchange device is an industrial air conditioner, which regulates the temperature within the first housing space, thereby improving the working efficiency of the energy storage battery.

[0006] In the process of realizing this invention, the inventors discovered the following problems in the prior art:

[0007] In existing technologies, air cooling is used to dissipate heat from the battery. If the protection level of the battery pack is too high, the heat dissipation efficiency of the battery pack will be significantly reduced, and the protection level of the battery pack needs to be reduced, resulting in poor battery pack safety. In addition, there is no monitoring of the battery equipment to control the coolant equipment. Summary of the Invention

[0008] In view of the above problems, this application provides a temperature control system and a hybrid power station for a hybrid power station, which solves the technical problem that if the protection level of the battery pack is too high when using air cooling to dissipate heat from the battery, the heat dissipation efficiency of the battery pack will be significantly reduced, and the protection level of the battery pack needs to be reduced, resulting in poor battery pack safety; and that there is no technical problem of monitoring the battery equipment to control the coolant equipment.

[0009] To achieve the above objectives, in a first aspect, the inventor provides a temperature control system for a hybrid power plant, comprising:

[0010] Diesel generator;

[0011] The battery device, wherein the diesel generator is electrically connected to the battery device through an energy storage converter, and the diesel generator and the battery device can be connected individually or in parallel to provide power to external devices;

[0012] A coolant device is disposed on one side of the battery device, and the coolant device provides coolant to the battery device to dissipate heat from the battery.

[0013] At least one first temperature sensor, the first temperature sensor being used to monitor the temperature of the battery in the battery device; and

[0014] A controller is connected to the first temperature sensor and is used to receive the temperature signal of the battery of the battery device sent by the first temperature sensor. The controller is used to control the coolant device to provide coolant to the battery device according to the temperature signal of the battery of the battery device sent by the first temperature sensor.

[0015] Unlike existing technologies, the above-mentioned solution provides coolant to the battery pack via a coolant system, dissipating heat from the batteries. This eliminates the need for an outdoor air conditioning unit, preventing dust from being blown into the hybrid power station. It also boasts strong environmental adaptability. The liquid cooling system uses contact cooling, improving the battery pack's protection level and safety without affecting its heat dissipation efficiency. Furthermore, a first temperature sensor monitors the battery temperature, and the controller directs the coolant system to supply coolant, enabling automatic cooling without manual intervention and further enhancing heat dissipation efficiency.

[0016] In one embodiment of the present invention, the hybrid power station further includes a housing, the battery device, the energy storage converter, and the coolant device are disposed at one end of the housing, and the diesel generator is disposed at the other end of the housing;

[0017] The housing has a first air inlet at one end located on the energy storage converter, and an air outlet at one end located on the diesel generator.

[0018] The first air inlet is equipped with a first electronic valve, which is used to open or close the first air inlet. The temperature control system of the hybrid power station also includes a second temperature sensor, which is used to monitor the temperature signal of the energy storage converter and send the temperature signal to the controller. The controller is also used to control the first electronic valve according to the temperature signal of the energy storage converter sent by the second temperature sensor.

[0019] In this way, by cooperating with the controller, when the second temperature sensor detects that the temperature of the energy storage converter is too high, the first air inlet will be opened to the maximum air inlet angle to accelerate the airflow to dissipate heat from the energy storage converter. The cooled air is then supplied to the diesel generator, which can reduce the temperature difference between the energy storage converter and the diesel generator. The air around the energy storage converter is used to cool the diesel generator and improve the airflow around the diesel generator.

[0020] As one embodiment of the present invention, the first air inlet is provided along the width direction of the housing, and the second air inlet is provided along the length direction of the housing at one end of the energy storage converter.

[0021] A second electronic valve is provided on the second air inlet, and the controller is connected to and controls the second electronic valve.

[0022] In this way, the first air inlet and the second air inlet can be opened or closed simultaneously by the controller, which can further accelerate the heat dissipation of the energy storage converter and speed up the flow of gas.

[0023] In one embodiment of the present invention, the battery device is located on one side of the energy storage converter along the length of the housing, and the housing is provided with a third air inlet on the outside of the battery device.

[0024] A third electronic valve is provided on the third air inlet, and the controller is connected to and controls the third electronic valve.

[0025] Thus, when the battery device temperature is too high, the controller can not only control the coolant device to accelerate the flow of coolant, but also control the third air inlet to allow air to enter. When used together, this can accelerate the heat dissipation of the battery device and speed up the gas flow.

[0026] In one embodiment of the present invention, the housing is provided with a fourth air inlet on the outside of the diesel generator, and the fourth air inlet, the third air inlet, and the second air inlet are arranged sequentially along the length of the housing.

[0027] The fourth air inlet is equipped with a fourth electronic valve. The temperature control system of the hybrid power station also includes a third temperature sensor. The third temperature sensor is used to monitor the temperature signal of the diesel generator and send the temperature signal to the controller. The controller is also used to control the fourth electronic valve according to the temperature signal of the diesel generator sent by the third temperature sensor.

[0028] In this way, the temperature signal of the diesel generator can be monitored by the third temperature sensor, and the fourth air inlet can be opened or closed to accelerate the cooling of the diesel generator and speed up the flow of gas.

[0029] In one embodiment of the present invention, the fourth air inlet, the third air inlet, the second air inlet, and the first air inlet are all disposed on the housing via a door panel, and the door panel is hinged to the housing.

[0030] Thus, the fourth, third, second, and first air inlets are mounted on the cabinet via door panels, which are hinged to the cabinet for easy maintenance and repair. By simply rotating the door panels out, both sides of the fourth, third, second, and first air inlets can be easily maintained and repaired.

[0031] In one embodiment of the present invention, a dustproof net is provided behind the fourth air inlet, the third air inlet, the second air inlet, and the first air inlet of the housing.

[0032] In this way, dust can be prevented from entering the hybrid power plant through dustproof netting.

[0033] As one embodiment of the present invention, the hybrid power station further includes a partition that divides the housing into a first space and a second space. The diesel generator, the battery device, and the energy storage converter are located in the first space, and the air outlet is located in the second space. The housing has an air outlet along the width of the housing and an air outlet on the top of the housing.

[0034] In this way, the air inlets of the diesel generator, battery equipment, and energy storage converter can be separated from the air outlet of the diesel generator by a partition. Since incomplete combustion of fuel often occurs, the temperature of the diesel generator's air outlet is the highest. Separating all the air inlets from the diesel generator's air outlet can ensure that the temperature of the diesel generator's air outlet does not affect other equipment and can improve the heat dissipation of the diesel generator's air outlet.

[0035] In one embodiment of the present invention, the battery device includes a frame, two or more battery packs, and a battery management module. The two or more battery packs are arranged sequentially on the frame in a vertical direction. The battery management module is arranged on the frame. All the battery packs are electrically connected to the battery management module. The battery management module is connected to the controller.

[0036] In this way, the battery management module can directly monitor the battery temperature of two or more battery packs and send the temperature of all batteries to the controller, which then controls the coolant system to dissipate heat from the batteries in the battery pack.

[0037] To achieve the above objectives, in a second aspect, the inventors provide a hybrid power station including a temperature control system for the hybrid power station as described in any of the aforementioned inventors' claims.

[0038] Unlike existing technologies, the hybrid power station solution in this application provides coolant to the battery pack via a coolant system, thus dissipating heat from the batteries. This eliminates the need for an outdoor air conditioning unit, preventing dust from being blown into the hybrid power station. It exhibits strong environmental adaptability, and the contact-type liquid cooling improves the battery pack's protection level and safety without affecting its heat dissipation efficiency. Simultaneously, a first temperature sensor monitors the battery temperature, and a controller directs the coolant system to supply coolant, enabling automatic control of the coolant system to dissipate heat from the batteries without manual intervention, thereby improving heat dissipation efficiency.

[0039] The above description of the invention is merely an overview of the technical solution of this application.

[0073] In the existing technology, air cooling is used to dissipate heat from the battery. If the protection level of the battery pack 35 is too high, the heat dissipation efficiency of the battery pack 35 will be significantly reduced, and the protection level of the battery pack 35 needs to be reduced, resulting in poor safety of the battery pack 35. In addition, there is no monitoring of the battery device 3 to control the coolant device 4.

[0074] The applicant's research found that liquid cooling can be used to dissipate heat from the batteries in battery device 3, eliminating the need for an outdoor air conditioning unit. This eliminates concerns about dust being blown into the hybrid power station by the air conditioning unit, demonstrating strong environmental adaptability. Liquid cooling, using a contact-type heat dissipation method, can improve the protection level and safety of battery pack 35 without affecting the battery's heat dissipation efficiency. Simultaneously, by monitoring the battery temperature of battery device 3 through a first temperature sensor 71, and controlling the coolant device 4 to supply coolant to battery device 3, the coolant device 4 can automatically control the heat dissipation of the batteries in battery device 3, eliminating the need for manual operation and improving heat dissipation efficiency.

[0075] The temperature control system and hybrid power station involved in this embodiment can be applied to various aspects of the energy storage technology field.

[0076] According to some embodiments of this application, please refer to Figures 1 to 9 This embodiment relates to a temperature control system for a hybrid power station, including a diesel generator 2, a battery device 3, a coolant device 4, at least one first temperature sensor 71, and a controller 7. The diesel generator 2 is electrically connected to the battery device 3 through an energy storage converter 5. The diesel generator 2 and the battery device 3 can be connected individually or in parallel to provide power to external devices. The coolant device 4 is located on one side of the battery device 3 and provides coolant to the battery device 3 to dissipate heat from the battery.

[0077] The first temperature sensor 71 is used to monitor the temperature of the battery of the battery device 3; the controller 7 is connected to the first temperature sensor 71 and is used to receive the temperature signal of the battery of the battery device 3 sent by the first temperature sensor 71. The controller 7 is used to control the coolant device 4 to provide coolant to the battery device 3 according to the temperature signal of the battery of the battery device 3 sent by the first temperature sensor 71.

[0078] In this embodiment, the coolant device 4 is disposed on one side of the battery device 3. The battery device 3 is provided with a channel 31 through which coolant can pass. The coolant device 4 is connected to one end of the channel 31 through an inlet pipe 32, and the other end of the channel 31 is connected to the coolant device 4 through an outlet pipe 33. The coolant device 4 provides coolant to the battery device 3 to dissipate heat from the battery of the battery device 3.

[0079] In this embodiment, the diesel generator 2 adopts a technical solution with the fuel tank at the bottom. The diesel generator 2 itself includes a muffler, an air inlet and an exhaust port, and its exhaust port and muffler are separated from other components of the diesel generator 2.

[0080] In this embodiment, the battery device 3 is arranged in a cabinet manner, with the battery pack 35 stacked on the rack 34.

[0081] In this embodiment, the energy storage converter 5, a bidirectional energy storage inverter (PCS), is used in AC-coupled energy storage systems such as grid-connected energy storage and microgrid energy storage. It connects the battery bank and the power grid (or load) and is a device that enables bidirectional energy conversion. It can convert the DC power from the battery into AC power for supply to the power grid or AC loads; it can also rectify the AC power from the power grid into DC power to charge the battery. In this embodiment, the diesel generator 2 can charge the battery in the battery device 3 through the energy storage converter 5.

[0082] In this embodiment, the coolant device 4 is a coolant supply device that provides power for the flow of coolant.

[0083] In this embodiment, the coolant device 4 provides coolant to the battery device 3 to dissipate heat from the battery, eliminating the need for an outdoor air conditioning unit. This eliminates concerns about dust being blown into the hybrid power station by the air conditioning unit, demonstrating strong environmental adaptability. The liquid cooling uses contact cooling, which improves the protection level and safety of the battery pack 35 without affecting its heat dissipation efficiency. Simultaneously, the temperature of the battery in the battery device 3 is monitored by the first temperature sensor 71, and the controller 7 controls the coolant device 4 to supply coolant to the battery device 3. This allows for automatic control of the coolant device 4 to dissipate heat from the battery, eliminating the need for manual operation and improving heat dissipation efficiency.

[0084] According to some embodiments of this application, optionally, the hybrid power station further includes a housing 1, with the battery device 3, energy storage converter 5, and coolant device 4 disposed at one end of the housing 1, and the diesel generator 2 disposed at the other end of the housing 1; the housing 1 is provided with a first air inlet 12 at the end located near the energy storage converter 5, and an air outlet 19 at the end located near the diesel generator 2; a first electronic valve 72 is provided on the first air inlet 12, which is used to open or close the first air inlet 12; the temperature control system of the hybrid power station further includes a second temperature sensor 73, which is used to monitor the temperature signal of the energy storage converter 5 and send the temperature signal to the controller 7; the controller 7 is also used to control the first electronic valve 72 according to the temperature signal of the energy storage converter 5 sent by the second temperature sensor 73.

[0085] In this embodiment, each air inlet is equipped with an air inlet louver. The air inlet louver can be controlled by a motor to start or close the air inlet. The first electronic valve 72 is used to control the forward and reverse rotation of the motor. The electronic valve works on a similar principle to an electric curtain. The opening size of the air inlet louver can be adjusted to fully open, partially open, or closed.

[0086] In this embodiment, the container 1 is a container-type container 1, and the four corners of the container 1 are provided with lifting holes for easy hoisting.

[0087] In this embodiment, the housing 1 is provided with a power interface 11, the diesel generator 2 is connected to the power interface 11, and the battery device 3 is connected to the power interface 11 through the energy storage converter 5. The diesel generator 2 and the battery device 3 can provide power to external devices individually or in parallel. There is only one power interface 11, and the diesel generator 2 and the battery device 3 can be powered individually or in parallel by switching through software.

[0088] In this embodiment, to ensure the weight balance of the container body 1 and prevent one end of the container body 1 from being heavier than the other, the heavy diesel generator 2 is placed separately at one end of the container body 1, while the battery device 3, energy storage converter 5, and coolant device 4 are placed together at the other end of the container body 1.

[0089] In other embodiments, since the weights of the diesel generator 2, battery device 3, energy storage converter 5, and coolant device 4 are not fixed, multiple mounting through holes that mate with the diesel generator 2, battery device 3, energy storage converter 5, and coolant device 4 can be provided on the housing 1 along its length. During installation, the installation positions of the diesel generator 2, battery device 3, energy storage converter 5, and coolant device 4 can be adjusted through calculation to ensure that the weights at both ends of the housing 1 are similar, preventing weight concentration. Theoretically, the weight of the diesel generator 2 when not fully loaded with diesel fuel should be slightly less than the total weight of the battery device 3, energy storage converter 5, and coolant device 4. This ensures that, in actual use, the difference between the weight of the diesel generator 2 plus diesel fuel and the total weight of the battery device 3, energy storage converter 5, and coolant device 4 does not exceed a preset value, preventing the housing 1 from tilting to one side during transportation and installation.

[0090] In this way, by cooperating with the controller 7, when the second temperature sensor 73 detects that the temperature of the energy storage converter 5 is too high, the first air inlet 12 will be opened to the maximum air inlet angle to accelerate the airflow to dissipate heat from the energy storage converter 5. The air after heat dissipation is supplied to the diesel generator 2, which can reduce the temperature difference between the energy storage converter 5 and the diesel generator 2, and use the air around the energy storage converter 5 to cool the diesel generator 2 and improve the airflow around the diesel generator 2.

[0091] According to some embodiments of this application, optionally, the first air inlet 12 is arranged along the width direction of the housing 1, and the second air inlet 13 is arranged along the length direction of the housing 1 at one end of the energy storage converter 5; a second electronic valve 74 is arranged on the second air inlet 13, and the controller 7 is connected to and controls the second electronic valve 74.

[0092] Since the second temperature sensor 73 can monitor the temperature of the energy storage converter 5, when the temperature of the energy storage converter 5 is too high, the controller 7 can open the first air inlet 12 or the second air inlet 13 separately. When the temperature of the energy storage converter 5 exceeds the preset value, the first air inlet 12 and the second air inlet 13 need to be fully opened so that air can enter from both sides simultaneously.

[0093] In this way, the controller 7 can simultaneously open or close the first air inlet 12 and the second air inlet 13, further accelerating the heat dissipation of air on the energy storage converter 5 and speeding up the flow of gas.

[0094] According to some embodiments of this application, optionally, the battery device 3 is located on one side of the energy storage converter 5 along the length of the housing 1, and the housing 1 is provided with a third air inlet 14 on the outside of the battery device 3; a third electronic valve 75 is provided on the third air inlet 14, and the controller 7 is connected to and controls the third electronic valve 75.

[0095] Since the first temperature sensor 71 can detect the temperature of the battery inside the battery device 3, when the battery is too hot, it can easily transfer the temperature to the rack 34. Therefore, the battery device 3 can be cooled down, and the overall temperature of the battery device 3 can be reduced.

[0096] Thus, when the temperature of the battery device 3 is too high, the controller 7 can not only control the coolant device 4 to accelerate the flow of coolant, but also control the third air inlet 14 to allow air to enter. In combination, this can accelerate the heat dissipation of the battery device 3 and speed up the flow of gas.

[0097] According to some embodiments of this application, optionally, a fourth air inlet 15 is provided on the outside of the diesel generator 2 in the housing 1, and the fourth air inlet 15, the third air inlet 14, and the second air inlet 13 are arranged sequentially along the length of the housing 1; a fourth electronic valve 77 is provided on the fourth air inlet 15, and the temperature control system of the hybrid power station also includes a third temperature sensor 76, which is used to monitor the temperature signal of the diesel generator 2 and send the temperature signal to the controller 7. The controller 7 is also used to control the fourth electronic valve 77 according to the temperature signal of the diesel generator 2 sent by the third temperature sensor 76.

[0098] The air intake of the fourth air inlet 15 can be controlled according to the temperature of the diesel generator 2.

[0099] In this way, the temperature signal of the diesel generator 2 can be monitored by the third temperature sensor 76, and the fourth air inlet 15 can be opened or closed to accelerate the heat dissipation of the diesel generator 2 and speed up the flow of gas.

[0100] According to some embodiments of this application, optionally, the fourth air inlet 15, the third air inlet 14, the second air inlet 13, and the first air inlet 12 are all disposed on the housing 1 via a door panel 16, and the door panel 16 is hinged to the housing 1.

[0101] Thus, the fourth air inlet 15, the third air inlet 14, the second air inlet 13, and the first air inlet 12 are mounted on the housing 1 via the door panel 16. The door panel 16 is hinged to the housing 1, making it convenient to repair and maintain the fourth air inlet 15, the third air inlet 14, the second air inlet 13, and the first air inlet 12. By simply rotating the door panel 16 out, both sides of the fourth air inlet 15, the third air inlet 14, the second air inlet 13, and the first air inlet 12 can be easily repaired and maintained.

[0102] According to some embodiments of this application, optionally, a dustproof net 17 is provided behind the fourth air inlet 15, the third air inlet 14, the second air inlet 13, and the first air inlet 12 of the housing 1.

[0103] In this way, dust can be prevented from entering the hybrid power plant by using the dustproof net 17. The dustproof net 17 itself is removable, which facilitates subsequent maintenance and repair.

[0104] According to some embodiments of this application, optionally, the hybrid power station also includes a partition 18 that divides the housing 1 into a first space and a second space. The diesel generator 2, battery equipment 3, and energy storage converter 5 are located in the first space, and the air outlet 19 is located in the second space. The housing 1 has an air outlet 19 along the width direction of the housing 1, and an air outlet 19 is provided on the top of the housing 1.

[0105] In this way, the air inlets of the diesel generator 2, battery equipment 3, and energy storage converter 5 can be separated from the air outlet 19 of the diesel generator 2 by the partition 18. Since incomplete combustion of fuel often occurs, the temperature of the air outlet 19 of the diesel generator 2 is the highest. Separating all the air inlets from the air outlet 19 of the diesel generator 2 can ensure that the temperature of the air outlet 19 of the diesel generator 2 does not affect other equipment and can improve the heat dissipation of the air outlet 19 of the diesel generator 2.

[0106] According to some embodiments of this application, optionally, the battery device 3 includes a frame 34, two or more battery packs 35, and a battery management module 36. The two or more battery packs 35 are arranged sequentially on the frame 34 in a vertical direction. The battery management module 36 is arranged on the frame 34. All battery packs 35 are electrically connected to the battery management module 36. The battery management module 36 is connected to the controller 7.

[0107] All battery packs 35 have a channel 31 at the bottom for coolant to pass through. The inlet pipe 32 is connected to one end of the channel 31 through a first manifold 37, and the other end of the channel 31 is connected to the outlet pipe 33 through a second manifold 38.

[0108] The battery management module 36 is a conventional BMS battery system. It is designed to intelligently manage and maintain each battery cell, prevent overcharging and over-discharging, extend battery life, and monitor battery status.

[0109] In this embodiment, the battery management module 36 can manage the connection and control of the coolant device 4. The battery management module 36 collects the status of the battery to control whether the coolant device 4 needs to dissipate heat from the battery, whether to turn it on or off; or whether to speed up the flow of coolant to improve heat dissipation efficiency or slow down the flow of coolant to reduce heat dissipation efficiency. The battery management module 36 can provide control signals to the coolant device 4 to facilitate the use of the coolant device 4.

[0110] In this embodiment, the batteries inside the battery pack 35 are placed on the channel 31. After placement, the casing of the battery pack 35 is locked with bolts.

[0111] In this embodiment, one end of the channel 31 of all battery packs 35 is connected to the first current collector 37 through the first connecting pipe 371, and the other end of the channel 31 is connected to the second current collector 38 through the second connecting pipe 372.

[0112] In this way, the battery management module 36 can directly monitor the battery temperature of two or more battery packs 35 and send the temperature of all batteries to the controller 7. The controller 7 controls the coolant device 4 to dissipate heat from the batteries in the battery device 3.

[0113] According to some embodiments of this application, optionally, the containerized hybrid power station also includes a cable groove 6, which is disposed at the bottom of the top cover of the container 1. The cables 61 between the diesel generator 2 and the energy storage converter 5 and the power interface 11, and the cables 61 between the battery device 3 and the energy storage converter 5 and the power interface 11 are all arranged in the cable groove 6. The liquid inlet pipe 32 and the liquid outlet pipe 33 are arranged at the bottom of the container 1, and the fuel tank of the diesel generator 2 is disposed at the bottom of the container 1.

[0114] In this embodiment, the connecting cables 61 between the diesel generator 2, power interface 11, battery device 3, energy storage converter 5, and coolant device 4 are all routed from the top of the housing 1 and installed in the cable groove 6. Meanwhile, the coolant and fuel tank of the diesel generator 2, and the liquid pipes between the battery device 3 and the coolant device 4, are all routed from the bottom of the housing 1, achieving electrical-water separation.

[0115] In this way, all the cables 61 can be routed through the cable groove 6 and concentrated on the top cover of the container 1. The inlet pipe 32, the outlet pipe 33, and the fuel tank of the diesel generator 2 can be routed at the bottom of the container 1, thus separating electricity and water and improving the safety of the containerized hybrid power station.

[0116] This embodiment also relates to a hybrid power station, including a temperature control system for a hybrid power station as described above.

[0117] The containerized hybrid power station system includes the aforementioned hardware components as well as software components. Through software parameter settings, the output power of the diesel generator 2 and battery unit 3, the control logic of the coolant unit 4, and so on, can be configured. All software parameter settings can be configured via the control mechanism located above the power interface 11. Whether the diesel generator 2 and battery unit 3 output individually or in parallel is also set by the control mechanism.

[0118] Unlike existing technologies, the hybrid power station solution of this application provides coolant to the battery pack 3 through a coolant device 4, dissipating heat from the battery. This eliminates the need for an outdoor air conditioning unit, eliminating concerns about dust being blown into the hybrid power station. It exhibits strong environmental adaptability, and the liquid cooling uses contact-type heat dissipation, improving the protection level and safety of the battery pack 35 without affecting its heat dissipation efficiency. Simultaneously, a first temperature sensor 71 monitors the temperature of the battery in the battery pack 3, and the controller 7 controls the coolant device 4 to supply coolant to the battery pack 3. This enables automatic control of the coolant device 4 to dissipate heat from the battery, eliminating the need for manual operation and further improving heat dissipation efficiency.

[0119] In this embodiment, the sensor uses a sensing element and a conversion element to convert a specific measured signal into a usable signal according to a certain rule and output it to meet the requirements of information transmission, processing, recording, display, and control. The sensor can sense physical quantities such as force, temperature, light, sound, and chemical composition, and can convert them into electrical quantities such as voltage and current, or into the on / off state of a circuit, according to a certain rule. A sensor generally consists of a sensing element and a conversion element, and is the primary link in realizing automatic detection and automatic control. The function of the sensor is to convert non-electrical quantities into electrical quantities or the on / off state of a circuit, thereby enabling convenient measurement, transmission, processing, and control.

[0120] In this embodiment, the controller receives signals transmitted from the sensors and controls the actuators or execution units according to the signals transmitted from the sensors. The controller refers to the master command device that controls the starting, speed regulation, braking, and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence. It consists of a program counter, instruction register, instruction decoder, timing generator, and operation controller. It is the "decision-making body" that issues commands, that is, it coordinates and directs the operation of the entire computer system.

[0121] In this embodiment, the actuator or actuator unit includes, but is not limited to, compression mechanism, rotation mechanism, swing mechanism, vibration mechanism, lifting mechanism, cutting mechanism, etc.

Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of the present invention, or equivalent structural or procedural transformations made using the content of the present invention's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection of the present invention.
