Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the description of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] At present, the power supply modes of new energy vehicles are generally divided into two modes: charging with the vehicle and replacing the battery. Compared with the charging time of charging with the vehicle, the battery replacement station providing battery replacement service for the user's vehicle can keep the battery replacement time within 5 minutes by pre-storing electricity and charging the battery at a constant temperature, which is more likely to meet the strong demand of users for fast power supply.
[0036] In order to improve the energy utilization rate of the battery replacement station and provide a comfortable battery replacement environment for the staff and users, it is necessary to improve the energy efficiency ratio of the thermal management system of the battery replacement station. However, according to the understanding of the inventors, the current thermal management systems of the battery replacement station are independent of each other, for example, a separate water cooling unit is used for liquid cooling heat dissipation of the battery, a separate high-power industrial air conditioner is used for air cooling heat dissipation of the charging function unit (such as a charger), and two independent wall-mounted air conditioners are used for respectively controlling the temperature of the equipment room and the rest room, so that the entire thermal management system not only has a low energy efficiency ratio, but also has a problem of insufficient refrigeration or heating capacity in extreme weather, which seriously affects the charging rate and safety of the battery.
[0037] In order to solve the problem of low energy efficiency ratio of the existing thermal management system, it is necessary to improve or optimize the structure of the thermal management system of the battery replacement station.
[0038] Embodiment one
[0039] Referring to Figure 1 The first embodiment of the present application provides a battery swap station thermal management system for controlling the temperature of a heat demand area in a battery swap station. The battery swap station thermal management system comprises a temperature energy supply system and an insulation box 13. The insulation box 13 is connected to the temperature energy supply system and at least one heat demand area in the battery swap station through an insulation pipeline or an adiabatic pipeline, and is used to store temperature energy provided by the temperature energy supply system and provide temperature energy for the heat demand area according to the cold or hot demand of the heat demand area. Specifically, the insulation box 13 refers to a device used to collect and store temperature heat generated by the temperature energy supply system, and is composed of an inner container, an insulation layer and an outer shell. Preferably, the inner container of the insulation box 13 is welded by SUS304 stainless steel (referring to austenitic stainless steel), the insulation layer is a polyurethane foam structure, and the outer shell is made of a thin stainless steel plate. It should be noted that the heat demand area at least includes one of the battery storage area, the charging area, the equipment room, the rest room and the fire-fighting box in the battery swap station. The battery storage area is used to store batteries to provide battery swap services for users' vehicles. The charging area is used to install charging equipment such as a charger to charge the batteries stored in the battery storage area. The equipment room is used to install electrical equipment related to the battery swap station, such as PLC, circuit breaker, air switch, gateway and servo driver, etc., to provide power supply and power conversion. The rest room is used to provide a resting place for the staff of the battery swap station or the users waiting for battery swap. The fire-fighting box is a fire-fighting emergency facility, mainly used for extinguishing the battery with thermal runaway.
[0040] In order to solve the problem of low energy efficiency ratio of the existing thermal management system, in the first embodiment, the temperature energy supply system of the battery swap station thermal management system at least includes one of a solar heating system 1, a charging unit cooling system 2 and a heat pump system 3.
[0041] The solar heating system 1 comprises a solar collector 11 and a first driving pump 12, and the solar collector 11, the first driving pump 12 and the heat preservation tank 13 are connected to each other through pipelines to form a solar heating loop. Specifically, the solar collector 11 refers to a device capable of absorbing solar radiation and transferring the generated heat energy to a working medium, and preferably, the solar collector 11 is a liquid collector; the first driving pump 12 refers to an institution that transmits the mechanical energy of a prime mover or other external energy to a working medium, so as to increase the energy or pressure of the working medium, so as to transport the working medium, such as a water pump. Preferably, the connecting pipe between the solar collector 11, the first driving pump 12 and the heat preservation tank 13 is an adiabatic pipe or a heat preservation pipe capable of reducing heat transfer and energy loss. Thus, in winter, sunny days and daytime, when the temperature difference between the solar collector 11 and the working medium in the heat preservation tank 13 is greater than or equal to a preset threshold, the staff opens the solar collector 11 and the first driving pump 12, and drives the working medium to flow along the connecting pipeline between the solar collector 11, the first driving pump 12 and the heat preservation tank 13 by the first driving pump 12, so as to transport the heat energy converted by the solar collector 11 to the working medium in the heat preservation tank 13 for heat storage or to provide temperature energy to the heat demand area. It should be noted that the working medium herein includes but is not limited to liquid working medium such as water and emulsion.
[0042] And / or, the charging unit cooling system 2 comprises a second driving pump 21 and a charging unit 22, and the second driving pump 21, the charging unit 22 and the heat preservation tank 13 are also connected to each other through pipelines to form a waste heat recovery loop. Specifically, the structure of the second driving pump 21 is the same as that of the first driving pump 12, and will not be described here; the charging unit 22 refers to a charging unit with a liquid cooling device, which can dissipate the heat generated when charging the battery 5 in time, and at least includes a liquid cooling device for reducing the temperature of the charging unit 22, a control circuit for monitoring and controlling the charging state of the battery 5 in real time, a power supply module for converting the power of the mains or other external power into the required charging power, and an interface module for communicating with external devices, so that the liquid working medium flows in the charging unit 22 for heat dissipation, and provides the battery 5 with an appropriate charging voltage and charging current. It should be noted that the battery 5 herein refers to a battery that provides power for a vehicle, i.e. a power battery. Thus, when the charging unit 22 is electrically connected to at least one battery 5, i.e. charges at least one battery 5, the staff opens the second driving pump 21, and drives the working medium to flow along the connecting pipeline between the second driving pump 21, the charging unit 22 and the heat preservation tank 13 by the second driving pump 21, so as to transport the heat generated by the charging unit 22 in the form of heat exchange to the working medium in the heat preservation tank 13 for heat storage or to provide temperature energy to the heat demand area.
[0043] And / or, the heat pump system 3 includes a heat pump unit 31 and a third drive pump 32, and the heat pump unit 31, the third drive pump 32, and the insulation box 13 are also interconnected through pipelines to form a heat pump transfer loop. Specifically, the heat pump unit 31 refers to a dual-purpose cold and heat source device that can cool in summer and heat in winter, and can be an air source heat pump, a ground source heat pump, or a water source heat pump; the structure of the third drive pump 32 is the same as that of the first drive pump 12 and the second drive pump 21, and will not be described again here. Thus, when the heating capacity of the solar heating system 1 and the charging unit cooling system 2 cannot meet the heating needs of the heat demand area, or when at least one of the solar heating system 1 and the charging unit cooling system 2 is not running, the staff can turn on the heat pump unit 31 and the third drive pump 32. The third drive pump 32 drives the working medium to flow along the connecting pipe between the heat pump unit 31, the third drive pump 32 and the insulation box 13, so that the heat generated by the heat pump unit 31 during operation can be transferred to the working medium in the insulation box 13 for heat storage or to provide temperature energy to the heat demand area.
[0044] Furthermore, to facilitate the desired control of the solar heating circuit, the solar heating system 1 also includes two first solenoid valves 14. One of these first solenoid valves 14 is located on the inlet branch between the solar collector 11 and the insulation box 13, and the other is located on the outlet branch between the solar collector 11 and the insulation box 13. This allows for the control of parameters such as the flow direction, flow rate, and velocity of the working medium within the connecting pipe between the solar collector 11 and the insulation box 13. It should be noted that the inlet branch and outlet branch mentioned here and below are relative to the insulation box 13; that is, the branch into which the working medium is injected is the inlet branch, and the branch out of the insulation box 13 is the outlet branch.
[0045] Furthermore, to coordinate with the waste heat recovery loop and achieve the desired control, the charging unit cooling system 2 also includes two three-way valves 23 and a heat dissipation module 24 located between the two three-way valves 23. One of the three-way valves 23 is located on the liquid inlet branch between the charging unit 22 and the insulation box 13, and the other is located on the liquid outlet branch between the charging unit 22 and the insulation box 13. The two three-way valves 23 are interconnected with the heat dissipation module 24 via pipelines. This system not only controls the flow direction, flow rate, and velocity of the working medium within the connecting pipeline between the charging unit 22 and the insulation box 13, but also dissipates heat from at least a portion of the working medium flowing out of the charging unit 22. The cooled working medium can then flow through the three-way valves 23 to the liquid inlet branch of the charging unit 22, allowing the injection of a lower-temperature working medium into the charging unit 22, thereby cooling the charging unit 22. It should be noted that the heat dissipation module 24 includes, but is not limited to, components such as a radiator and a cooling fan.
[0046] Furthermore, to achieve the desired control in conjunction with the heat pump transfer circuit, the heat pump system 3 also includes several second solenoid valves 33. These second solenoid valves 33 are located on the liquid outlet branch between the heat pump system 3 and the insulation box 13, and correspond to several batteries 5 located on the liquid outlet branch between the heat pump system 3 and the insulation box 13 within the battery swapping station. Specifically, the working medium flow channel inside each battery 5 is connected to the liquid outlet branch between the heat pump system 3 and the insulation box 13 through the corresponding second solenoid valve 33. Thus, during winter, when any battery 5 in the battery storage area requires heating, the operator opens the third drive pump 32 and the second solenoid valve 33 corresponding to the battery 5 requiring heating. The third drive pump 32 drives the working medium to flow along the connecting pipeline between the insulation box 13, the third drive pump 32, the second solenoid valve 33, the battery 5, and the heat pump unit 31. This allows the heat energy converted or generated by one of the solar heating system 1, the charging unit cooling system 2, and the heat pump system 3 during operation to provide temperature energy to the battery 5 in the heat demand area through heat exchange, ensuring that the battery 5 is charged or stored within a suitable temperature range.
[0047] Furthermore, to prevent the working medium inside the fire-fighting box from freezing in winter, the thermal management system of the battery swapping station also includes a third solenoid valve 61, which is located on the liquid outlet branch between the heat pump system 3 and the insulation box 13. Specifically, the third solenoid valve 61 is connected to the working medium channel inside the fire-fighting box and the heat pump unit 31 via pipelines, and is also connected to the third drive pump 32 and the insulation box 13 via pipelines. In addition, the third solenoid valve 61 is also connected in parallel with several second solenoid valves 33. Thus, during winter, when the working medium inside the fire box requires heating, the operator opens the third drive pump 32 and the third solenoid valve 61. The third drive pump 32 drives the working medium to flow along the connecting pipeline between the insulation box 13, the third drive pump 32, the third solenoid valve 61, the fire box, and the heat pump unit 31. This allows the heat energy converted or generated by one of the solar heating system 1, the charging unit cooling system 2, and the heat pump system 3 during operation to provide temperature energy to the fire box in the heat demand area through heat exchange, ensuring that the temperature of the working medium inside the fire box is higher than its freezing point, thus preventing the working medium from freezing or icing.
[0048] In some embodiments, to prevent excessive heat absorption inside the fire-fighting box, a temperature sensor is installed in the fire-fighting box or the pipeline connected to the fire-fighting box to control the working medium inside the fire-fighting box within a specific temperature range. This prevents the working medium inside the fire-fighting box from solidifying or freezing, and also prevents the working medium inside the fire-fighting box from becoming too hot, which would be detrimental to the fire-fighting function. Preferably, a heat-conducting plate 62 is also installed on the fire-fighting box so that the high-heat working medium flowing out of the insulation box 13 can transfer heat to the working medium inside the fire-fighting box as it passes through the fire-fighting box.
[0049] Furthermore, to provide a comfortable environment for staff or users waiting to swap batteries in the rest area, the thermal management system of the battery swapping station also includes a fourth drive pump 71, a fourth solenoid valve 72, and a rest area indoor unit 73. The fourth drive pump 71 and the fourth solenoid valve 72 are located on the liquid outlet branch between the insulation box 13 and the rest area indoor unit 73. The fourth drive pump 71, the fourth solenoid valve 72, the rest area indoor unit 73, and the insulation box 13 are also interconnected via pipelines. Specifically, the structure of the fourth drive pump 71 is the same as that of the first drive pump 12, the second drive pump 21, and the third drive pump 32, and will not be described in detail here. The rest area indoor unit 73 can be a heat exchange device primarily for heating, such as a fan coil unit. Thus, during winter, when the rest room needs heating, staff can activate the fourth drive pump 71, the fourth solenoid valve 72, and the rest room indoor unit 73. The fourth drive pump 71 drives the working medium to flow along the connecting pipe between the insulation box 13, the fourth drive pump 71, the fourth solenoid valve 72, and the rest room indoor unit 73. This allows the heat energy converted or generated by one of the solar heating system 1, the charging unit cooling system 2, and the heat pump system 3 to provide temperature energy to the rest room in the heat demand area through heat exchange, providing a comfortable environment for the staff in the rest room or users waiting to exchange batteries.
[0050] Furthermore, to ensure that the equipment in the equipment room operates within a suitable temperature range, the thermal management system of the battery swapping station also includes a fifth solenoid valve 81 and an indoor unit 82. The fifth solenoid valve 81 is located on the liquid outlet branch between the insulation box 13 and the indoor unit 82. Specifically, the fifth solenoid valve 81 is connected to the fourth drive pump 71 and the insulation box 13 via a pipeline, and also to the indoor unit 82 via a pipeline. The structure of the indoor unit 82 is the same as that of the indoor unit 73 in the rest area, and will not be described further here. Thus, in winter, when the equipment room requires heating, staff can activate the fourth drive pump 71, the fifth solenoid valve 81, and the indoor unit 82. The fourth drive pump 71 drives the working medium to flow along the connecting pipeline between the insulation box 13, the fourth drive pump 71, the fifth solenoid valve 81, and the indoor unit 82. This allows the heat energy converted or generated by one of the solar heating system 1, the charging unit cooling system 2, and the heat pump system 3 during operation to provide temperature energy to the equipment room in the heat demand area through heat exchange, providing a suitable operating environment for the equipment in the equipment room.
[0051] Furthermore, in order to coordinate with the waste heat recovery circuit and the heat pump transfer circuit to achieve the expected control, the thermal management system of the battery swapping station also includes a sixth solenoid valve 91 and a seventh solenoid valve 92. The sixth solenoid valve 91 is located on the liquid outlet branch between the fourth drive pump 71 and the insulation box 13, and the sixth solenoid valve 91 is connected in parallel with the fourth solenoid valve 72 and the fifth solenoid valve 81. The seventh solenoid valve 92 is located on the liquid outlet branch between the heat pump unit 31 and the insulation box 13, and the seventh solenoid valve 92 is connected to the third drive pump 32 through a pipeline, which is beneficial to the exchange of working media on the liquid inlet branch and the liquid outlet branch of the insulation box 13.
[0052] Furthermore, to supplement heating, the thermal management system of the battery swapping station also includes an electric heater 4, which is located on the liquid inlet branch between the heat pump unit 31 and the insulation box 13 of the heat pump system 3. Specifically, the electric heater 4 is an electric heating device capable of heating, maintaining, and warming the circulating working medium, so that the temperature of the heated working medium reaches the process requirements. Thus, when the solar collector 11, charging unit 22, and heat pump unit 31 are simultaneously providing heat, but still cannot meet the heating needs of all heat-demanding areas, the staff can turn on the electric heater 4 to transfer the heat energy from the electric heater 4 to the insulation box 13 to supplement the heating for the heat-demanding areas.
[0053] Since battery swapping stations are mostly installed outdoors, and their energy efficiency ratio is weather-dependent, in this embodiment, the thermal management system of the battery swapping station also includes a controller (not shown) for communication with a host computer, so as to control the opening or closing of the solar heating system 1, the charging unit cooling system 2, and the heat pump system 3 as needed. Specifically, the host computer refers to a computer that can directly issue control commands, generally a PC / host computer / master computer / upper computer, whose screen can display various signal changes (such as hydraulic pressure, water level, temperature, etc.); the controller uses the MC9S08DZ60 as the main control chip, generates PWM control signals based on the collected temperature information and fault feedback information, and realizes information interaction with the solar collector 11, the charging unit 22, and the heat pump unit 31 through the CAN network. Thus, during winter, when any battery 5 requires heating, the host computer of the battery swapping station communicates with the controller via the bus. Then, the controller controls the third drive pump 32 and the second solenoid valve 33 of the corresponding branch of the battery 5 requiring heating to open according to the heating command issued by the host computer, so as to heat the battery 5 in the battery storage area to the preset target temperature range, ensuring that the battery cell of the battery 5 works within a suitable temperature range.
[0054] To facilitate understanding of the inventive concept of this application and to demonstrate the high energy efficiency of the thermal management system for the battery swapping station, the working modes of the temperature energy supply system under different application scenarios can be understood according to the contents of Table 1 below during specific implementation.

[0057] It should be noted that in Table 1 above, "√" indicates that the program is running, and " / " indicates that it is not running.
[0058] Example 2
[0059] Please see Figure 2 The second embodiment of the present invention also provides a battery swapping station thermal management system. Most of the features of the battery swapping station thermal management system are the same as those of the battery swapping station thermal management system of the first embodiment. The difference is that the electric heater 4a of the second embodiment is located differently from the electric heater 4 of the first embodiment. The following is a detailed description.
[0060] In Embodiment 2, the electric heater 4a is installed inside the insulation box 13. Specifically, the electric heater 4a is installed at the bottom of the insulation box 13 and is electrically isolated from the working medium inside the insulation box 13. Thus, when the solar collector 11, charging unit 22, and heat pump unit 31 are simultaneously providing heat, but still cannot meet the heating needs of all heat-demanding areas, the staff can supplement the heat demand by turning on the electric heater 4a and transferring the heat energy from the electric heater 4a to the insulation box 13.
[0061] Example 3
[0062] A third embodiment of the present invention provides a battery swapping station, which includes at least one heat demand area and a battery swapping station thermal management system as described in the above embodiments. The temperature energy supply system of the battery swapping station thermal management system provides temperature energy, and the insulation box 13 of the battery swapping station thermal management system stores the temperature energy provided by the temperature energy supply system. The insulation box 13 is connected to the temperature energy supply system and at least one heat demand area of the battery swapping station through pipelines, and can also provide temperature energy to the heat demand area according to the heating and cooling needs of the heat demand area.
[0063] Compared to technical solutions that employ multiple independently operating thermal management systems, the thermal management system disclosed in this application enables the battery swapping station to integrate solar energy, waste heat from the charging unit 22, and heat generated by the heat pump unit 31 to heat one of the battery storage area, charging area, equipment room, rest room, and fire box under low-temperature conditions in winter. Under high-temperature conditions in summer, it can also utilize the cooling of the heat pump unit 31 to cool one of the battery storage area, charging area, equipment room, and rest room, thus featuring high energy efficiency and strong cooling and heating capabilities.
[0064] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
