In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0033] Example 1

[0034] like Figure 1 As shown, this embodiment proposes a prefabricated cabin energy storage cooling thermal management system, including a first temperature detection unit, a second temperature detection unit, a third temperature detection unit, an air-conditioning control unit, a first air circulation control unit and a processor; the first temperature detection unit is used to detect the temperature of the battery pack, and the first temperature detection unit is connected to the processor; the second temperature detection unit and the third temperature detection unit are both used to detect the ambient temperature of the prefabricated cabin, and the second temperature detection unit and the third temperature detection unit are both connected to the processor; the air-conditioning control unit is connected to the processor, and the air-conditioning control unit is used to cool the prefabricated cabin; the first air circulation control unit is connected to the processor, and the first air circulation control unit is used to circulate the internal air in the prefabricated cabin.

[0035] The prefabricated cabin mentioned in this embodiment is an energy storage prefabricated cabin. The energy storage prefabricated cabin will generate a lot of heat when working. If the heat is not effectively dissipated, it will affect the working performance of the energy storage prefabricated cabin. The battery pack is an important component of the energy storage prefabricated cabin. The battery pack is the main source of heat generation. If the temperature of the battery pack is too high, it will affect the performance and life of the battery pack. In severe cases, it may even cause thermal runaway and safety accidents of the battery pack. During the charging and discharging process of the battery pack, the charging and discharging efficiency of the battery pack determines the amount of heat generated by the battery pack. The greater the charging and discharging efficiency of the battery pack, the smaller the heat generated. Therefore, proper cooling can keep the battery pack within the optimal operating temperature range and improve the energy conversion efficiency.

[0036] In this embodiment, the first temperature detection unit is used to detect the temperature of the battery pack, and converts the detected temperature signal of the battery pack into an electrical signal and sends it to the processor. The processor determines the temperature of the battery pack by the size of the electrical signal output by the first temperature detection unit. When the temperature of the battery pack exceeds the set value, the processor sends a control instruction to the air conditioning control unit, and the air conditioning control unit is used to cool the prefabricated cabin, thereby reducing the temperature of the battery pack. When working, the cold air output by the air conditioning control unit is in a fixed direction, which will cause inconsistent temperatures in the prefabricated cabin, and will also affect the overall working performance of the energy storage prefabricated cabin. To this end, in this embodiment, a second temperature detection unit and a third temperature detection unit are respectively provided at both ends of the prefabricated cabin. The second temperature detection unit and the third temperature detection unit are respectively used to detect the ambient temperature in the prefabricated cabin, and convert the detected temperature signals into electrical signals and send them to the processor. The processor determines the temperature difference at different positions in the prefabricated cabin according to the electrical signals output by the second temperature detection unit and the third temperature detection unit. When the temperature difference reaches a set value, the processor sends a control instruction to the first air circulation control unit. The first air circulation control unit is used to circulate the air in the prefabricated cabin to ensure that the cold air in the prefabricated cabin is evenly distributed, so that the overall temperature of the battery pack remains consistent, and at the same time ensure that the temperature of the battery pack is maintained within a reasonable range, thereby improving the overall working performance of the energy storage prefabricated cabin.

[0037] like Figure 1 As shown, a prefabricated cabin energy storage cooling thermal management system in this embodiment also includes a humidity detection unit and a second air circulation control unit; the humidity detection unit is used to detect the ambient temperature of the prefabricated cabin, and the humidity detection unit is connected to the processor; the second air circulation control unit is used to circulate the air inside the prefabricated cabin with the external air, and the second air circulation control unit is connected to the processor.

[0038] Humidity is one of the key environmental factors that affect the performance of prefabricated cabins. It not only affects the operating status of the equipment in the prefabricated cabin, but also causes corrosion to the physical structure and materials of the prefabricated cabin. For example, when the temperature in the prefabricated cabin is lower than the dew point temperature, water vapor in the air will condense on the surface of the cabin to form dew drops, which may cause problems such as short circuit and creepage of electrical equipment. In severe cases, it may even cause accidents such as flashover, short circuit and tripping. Excessive humidity can cause electrical components to come into contact with water, reduce their insulation performance and increase the risk of failure.

[0039] In order to avoid the above risks, the present embodiment provides a humidity detection unit in the prefabricated cabin. The humidity detection unit is used to detect the humidity signal in the prefabricated cabin and convert it into an electrical signal to send to the processor. When the humidity in the prefabricated cabin exceeds the set value, the processor sends a control instruction to the second air circulation control unit. The second air circulation control unit is used to exchange the air in the prefabricated cabin with the outside air, and discharge the air in the prefabricated cabin for circulation ventilation with the outside air, thereby reducing the air humidity in the prefabricated cabin and ensuring the stable performance of the prefabricated cabin.

[0040] In this embodiment, the first air circulation control unit and the second air circulation control unit can be implemented by controlling fans.

[0041] like Figure 1 As shown, a prefabricated cabin energy storage cooling thermal management system in this embodiment also includes a communication unit; the processor is communicatively connected to the remote terminal through the communication unit.

[0042] In order to monitor the prefabricated cabin in real time, a communication unit is further provided in this embodiment. The processor is connected to the remote terminal through the communication unit. A mobile phone and a computer can be used as the remote terminal to monitor the working status of the prefabricated cabin in real time.

[0043] like Figure 2 As shown, in this embodiment, the first temperature detection unit includes a resistor R3, a resistor R9, an amplifier U1, a resistor R2, a resistor R1, a transistor Q2 and a thermistor RT; the first end of the resistor R3 is used to connect to the VCC power supply, the second end of the resistor R3 is grounded through the resistor R9, the second end of the resistor R3 is connected to the non-inverting input end of the amplifier U1, the inverting input end of the amplifier U1 is grounded through the resistor R2, the output end of the amplifier U1 is connected to the base of the transistor Q2 through the resistor R1, the output end of the amplifier U1 is connected to the emitter of the transistor Q2 through the thermistor RT, the collector of the transistor Q2 is connected to the inverting input end of the amplifier U1, and the output end of the amplifier U1 is connected to the processor.

[0044] In this embodiment, the circuit structure of the second temperature detection unit and the third temperature detection unit is the same as the circuit structure of the first temperature detection unit. In this embodiment, the circuit of the first temperature detection unit is taken as an example, and the resistor R3, the resistor R9, the amplifier U1, the resistor R2, the resistor R1, the transistor Q2 and the thermistor RT constitute a temperature detection circuit. The thermistor RT is used to detect the temperature of the battery pack, and the resistance value of the thermistor RT changes with the temperature of the battery pack.

[0045] The first end of the resistor R3 is used to connect to the VCC power supply, the amplifier U1 constitutes an amplifier circuit, and the thermistor RT serves as the feedback resistor of the amplifier circuit. The thermistor RT in this embodiment has a positive temperature coefficient. When the temperature of the battery pack increases, the resistance of the thermistor RT increases, that is, the feedback resistor of the amplifier circuit increases, and the voltage output by the amplifier U1 increases. When the temperature of the battery pack decreases, the resistance of the thermistor RT decreases, that is, the feedback resistor of the amplifier circuit decreases, and the voltage output by the amplifier U1 also decreases. Finally, the voltage output by the amplifier U1 is sent to the processor, and the processor determines the temperature of the battery pack according to the voltage output by the amplifier U1.

[0046] like Figure 2 As shown, in this embodiment, the first temperature detection unit also includes a resistor R5, an amplifier U2, a resistor R6 and a capacitor C1; the first end of the resistor R5 is connected to the output end of the amplifier U1, the second end of the resistor R5 is connected to the in-phase input end of the amplifier U2, the output end of the amplifier U2 is connected to the inverting input end of the amplifier U1, the output end of the amplifier U2 is connected to the first end of the resistor R6, the second end of the resistor R6 is grounded through the capacitor C1, and the second end of the resistor R6 is connected to the processor.

[0047] In this embodiment, there is an interference signal in the electrical signal output by the amplifier U1, which may cause the temperature detection result to be unstable. For this reason, the resistor R6 and the capacitor C1 form a filter circuit to improve the accuracy of temperature detection. At the same time, an amplifier U2 is added between the amplifier U1 and the resistor R6. The amplifier U2 forms a follower to reduce the signal loss on the line and further improve the accuracy of temperature detection.

[0048] like Figure 2 As shown, the first temperature detection unit of this embodiment also includes a resistor R11, a transistor Q1, a resistor R7, a resistor R18, a transistor Q3 and a transistor Q4; the VCC power supply is connected to the base of the transistor Q1 through the resistor R11, the collector of the transistor Q1 is connected to the VCC power supply, the emitter of the transistor Q1 is grounded through the resistor R7, the emitter of the transistor Q1 is connected to the base of the transistor Q3, the collector of the transistor Q3 is connected to the base of the transistor Q4, the collector of the transistor Q4 is connected to the VCC power supply, the VCC power supply is connected to the collector of the transistor Q3 through the resistor R18, the emitter of the transistor Q3 is grounded, and the emitter of the transistor Q4 is connected to the first end of the resistor R3.

[0049] Since the environment in the prefabricated cabin is relatively complex, the VCC power supply may be unstable, which will also affect the result of temperature detection. Therefore, resistor R11, transistor Q1, resistor R7, transistor Q3 and transistor Q4 constitute a constant current source. Transistor Q1 works in the switching state, and transistors Q3 and Q4 work in the amplification state respectively. When the current output by the VCC power supply increases, the voltage on resistor R9 will increase, and the voltage on resistor R7 increases, then the base current of transistor Q3 increases, so the current flowing through the collector of transistor Q3 increases, thereby reducing the base current of transistor Q4, which will reduce the current flowing through resistor R9, that is, suppress the voltage on resistor R9 from increasing.

[0050] When the current output by the VCC power supply decreases, the voltage on the resistor R9 will decrease, and the voltage on the resistor R7 will decrease, then the base current of the transistor Q3 will decrease, so the current flowing through the collector of the transistor Q3 will decrease, thereby increasing the base current of the transistor Q4, which will increase the current flowing through the resistor R9, that is, suppress the voltage on the resistor R9 from decreasing, thereby ensuring that the voltage applied to the in-phase input terminal of the amplifier U1 is stable and unchanged.

[0051] like Figure 3 As shown, the humidity detection unit in this embodiment includes a first humidity-sensitive resistor RH1, a capacitor C2, a second humidity-sensitive resistor RH2, a capacitor C3, a resistor R14, a resistor R13 and an amplifier U3; the in-phase input terminal of the amplifier U3 is grounded through the second humidity-sensitive resistor RH2, the capacitor C3 is connected in parallel at both ends of the second humidity-sensitive resistor RH2, the inverting input terminal of the amplifier U3 is grounded through the resistor R13, the output terminal of the amplifier U3 is connected to the inverting input terminal of the amplifier U3 through the resistor R14, the output terminal of the amplifier U3 is connected to the first end of the capacitor C2 through the first humidity-sensitive resistor RH1, the second end of the capacitor C2 is connected to the in-phase input terminal of the amplifier U3, and the output terminal of the amplifier U3 is connected to the processor.

[0052] In this embodiment, the first humidity-sensitive resistor RH1, the capacitor C2, the second humidity-sensitive resistor RH2, the capacitor C3, the resistor R14, the resistor R13 and the amplifier U3 constitute an oscillation circuit for outputting a sinusoidal oscillation signal, wherein the first humidity-sensitive resistor RH1 and the second humidity-sensitive resistor RH2 are used to detect the ambient humidity in the prefabricated cabin. According to the different humidity of the environment in the prefabricated cabin, the first humidity-sensitive resistor RH1 and the second humidity-sensitive resistor RH2 present different resistance values. By changing the corresponding resistance values ​​of the first humidity-sensitive resistor RH1 and the second humidity-sensitive resistor RH2, the frequency output by the oscillation circuit can be changed. Therefore, the ambient humidity in the prefabricated cabin can be determined by identifying the frequency output by the oscillation circuit. The amplifier U3 is used to output a sinusoidal oscillation signal and send the oscillation signal to the processor. When the humidity in the prefabricated cabin exceeds the set value, the processor sends a control instruction to the second air circulation control unit.

[0053] like Figure 3 As shown, the humidity detection unit in this embodiment also includes a diode D3, a capacitor C4, an amplifier U4, a resistor R16 and a resistor R15; the anode of the diode D3 is connected to the output end of the amplifier U3, the cathode of the diode D3 is grounded through the capacitor C4, the cathode of the diode D3 is connected to the inverting input end of the amplifier U4, the inverting input end of the amplifier U4 is connected to the Vref reference voltage, the non-inverting input end of the amplifier U4 is grounded through the resistor R16, the output end of the amplifier U4 is connected to the inverting input end of the amplifier U4 through the resistor R15, and the output end of the amplifier U4 is connected to the processor.

[0054] In this embodiment, the oscillation signal output by the oscillation circuit is a positive-negative alternating sinusoidal signal. Since the controller cannot receive negative signals, the positive-negative alternating sinusoidal signal output by the oscillation circuit needs to be processed.

[0055] Among them, the diode D3 and the capacitor C4 constitute a rectifier and filter circuit, which is used to convert the positive and negative alternating sinusoidal signal output by the amplifier U3 into a DC signal. The signal will produce certain losses after rectification and filtering, so that the amplitude of the output DC signal is smaller. For this reason, the amplifier U4 constitutes an amplifier circuit, which is used to amplify the DC signal, and finally sends the amplified DC signal to the processor. The processor determines the humidity in the prefabricated cabin according to the size of the DC signal.

Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
