[0027] Please refer to Figure 1The safety unit 10 in the energy storage thermal management and safety system mainly functions to rapidly spray a large amount of heat-absorbing substances to take away the heat generated by the battery unit 40 and avoid thermal chain reaction of the battery unit 40 when the battery unit 40 is about to have thermal runaway or the battery temperature rises sharply and combustion or even explosion may occur. The thermal management unit 20 mainly functions to control the battery unit 40 to work within the optimal working temperature range of the battery. The control unit 30 mainly functions to control the operation of the safety unit 10 and the thermal management unit 20 according to the working condition of the battery unit 40.

[0028] Please refer to Figure 2 The safety unit 10 includes a refrigerant storage tank 11, a pipeline 12 connected with the refrigerant storage tank 11 and the battery unit 40, and a solenoid valve 13 installed on the pipeline 12 and connected with the control unit 30. The battery unit 40 includes a battery box 42 and a battery module 41 located in the battery box 42. One end of the pipeline 12 connected with the battery unit 40 is provided with a pipeline opening 121, which is located in the battery box 42 and is arranged towards the battery module 41. The safety unit 10 further includes a temperature sensor 16 arranged in the battery box 42 and connected with the control unit 30. The temperature sensor 16 is used to sense the temperature information of the battery module 41 in real time and return the information to the control unit 30. In this embodiment, the temperature sensor 16 is arranged in close contact with the battery module 41 to accurately collect the temperature information of the battery module 41. In this embodiment, the refrigerant storage tank 11 stores R134a liquid.

[0029] Further, the safety unit 10 further includes a smoke sensor 15 arranged in the battery box 42 and connected with the control unit 30. The smoke sensor is used to sense the generated smoke information in the battery box 42 in real time and return the information to the control unit 30.

[0030] Further, the safety unit 10 further includes a fusible plug 14 arranged in the battery box 42 and located on the side of the solenoid valve 13 away from the pipeline opening 121.

[0031] In more detail, the safety unit has triple protection, the first protection: when the temperature rises to a certain temperature, the temperature sensor 16 transmits the temperature signal to the control unit 30, and when the control unit 30 calculates, compares and judges that the safety temperature is exceeded, it is determined that the battery module 41 is in a thermal runaway state, at this time, the control unit 30 sends a signal to the electromagnetic valve 13, the electromagnetic valve 13 is opened, the R134a liquid flows from the refrigerant storage tank 11 through the pipeline 12 and is rapidly injected from the pipeline opening 121 to the surface of the battery module 41 to evaporate, and the large amount of cold produced immediately makes the temperature of the battery module 41 drop rapidly, cutting off the thermal chain reaction of the battery module 41, thereby ensuring the safety of the battery module 41; the second protection: when the temperature sensor 16 fails, the control unit 30 cannot receive the signal of the excessively high temperature, the temperature of the battery module 41 will continue to rise, and the protective layer of the battery module 41 will overheat and produce smoke when the temperature rises, at this time, the smoke sensor 15 will sense the signal of the smoke and transmit the signal to the control unit 30, the control unit 30 sends a signal to the electromagnetic valve 13, the electromagnetic valve 13 is opened, the R134a liquid flows from the refrigerant storage tank 11 through the pipeline 12 and is rapidly injected from the pipeline opening 121 to the surface of the battery module 41 to evaporate, and the large amount of cold produced immediately makes the temperature of the battery module 41 drop rapidly, cutting off the thermal chain reaction of the battery module 41, thereby further ensuring the safety of the battery module 41; the third protection: when the temperature sensor 16, the smoke sensor 15 and the control unit 30 all fail, causing the electromagnetic valve 13 to fail to open normally, the third protection is started, in this embodiment, when the temperature of the battery module 41 rises to about 200 degrees, the battery module 41 has not caught fire, but as the temperature continues to rise, the thermal chain reaction of the battery module 41 will further intensify, if the battery module 41 is not cooled at this time, the thermal chain reaction will cause the temperature of the battery module to rapidly rise to about 500 degrees, and then the battery module 41 will burn or even explode, the third protection is that when the temperature of the battery module 41 rises to about 200 degrees, the metal plug in the fusible plug 14 will melt, the R134a liquid is rapidly injected from the refrigerant storage tank 11 through the pipeline 12 from the melting opening of the fusible plug 14, and the large amount of cold produced immediately makes the temperature of the battery module 41 drop rapidly, avoiding the danger of battery burning or explosion, and finally ensuring the safety of the battery module 41.

[0032] Please refer to Figure 3 and Figure 4The thermal management unit 20 adjusts the operating temperature of the battery module 41 in real time using its own cooling or heating mode to ensure that the battery module 41 operates within the set optimal temperature range of 25℃-30℃. When the operating temperature of the battery module 41 exceeds 30℃, the thermal management unit 20 activates the cooling mode (see [link to relevant documentation]). Figure 3 and Figure 4 (The solid line in the diagram, along with the arrow, represents the cooling circuit of the thermal management unit 20.) However, when the ambient temperature is too low, the temperature of the battery module 41 will also drop. When the temperature of the battery module 41 is too low, the activity of the internal materials of the battery module 41 will decrease rapidly, and the battery module 41 will experience self-discharge, causing the lifespan of the battery module 41 to decrease rapidly. At this time, it is necessary to activate the heating mode (see [link]). Figure 3 and Figure 4 The dashed line in the figure, along the direction of the dashed arrow, represents the heating circuit of the thermal management unit 20.

[0033] Please see Figure 3 In one embodiment of this utility model, the thermal management unit 20 includes a refrigeration compressor 21, a four-way valve 22, a condenser 23, a drying filter receiver 24, a throttling valve 25, and an evaporator 26. The refrigeration compressor 21 is connected to the four-way valve 22. Two of the four ports of the four-way valve 22 are respectively connected to the liquid inlet and liquid outlet of the condenser 23, and the other two ports are respectively connected to both ends of the liquid collection pipe 27 of the evaporator 26. Both ends of the drying filter receiver 24 are respectively connected to the liquid collection pipe 27 of the condenser 23 and the evaporator 26. In this embodiment, the evaporator 26 is located inside the battery housing 42 and is arranged around the battery module 41.

[0034] Furthermore, in this embodiment, the thermal management unit 20 has a refrigeration circuit and a heating circuit. In the refrigeration circuit, a throttling valve 25 is provided between the drying filter receiver 24 and the liquid collection pipe 27 of the evaporator 26.

[0035] More specifically, this invention uses the thermal management unit 20 to control the operating temperature of the battery module 41 between 25°C and 30°C. When the operating temperature of the battery module 41 exceeds 30°C, the thermal management unit 20 activates the cooling mode (see [link to relevant documentation]). Figure 3 ), Figure 3The solid line in the figure is a refrigeration circuit of the heat management unit 20, when the temperature sensor 16 senses that the temperature of the battery module 41 exceeds 30 DEG C, and transmits the information that the temperature of the battery module 41 exceeds 30 DEG C to the control unit 30, the control unit 30 sends a signal, the refrigeration compressor 21 starts refrigeration work, and R134a gas is compressed into high-temperature and high-pressure refrigerant gas, enters the condenser 23 through the four-way valve 22, and is cooled into medium-temperature and high-pressure refrigerant liquid, enters the dry filter liquid accumulator 24, and then is throttled and decompressed through the throttling valve 25, enters the evaporator 26 from the liquid collecting pipe 27 at one end, and the liquid refrigerant is changed into low-temperature and low-pressure refrigerant gas by heat absorption, and then flows back to the four-way valve 22 through the liquid collecting pipe 27 at the other end, and finally returns to the refrigeration compressor 21, and the cycle is completed. Since the refrigeration compressor 21 works continuously, the cold energy generated by the refrigeration circuit is used to offset the heat generated by the work of the battery module 41, so that the working temperature of the battery module 41 is kept within the optimal working temperature.

[0036] Generally, the battery module 41 generates heat as long as it works, so in most cases, it is in refrigeration mode. However, if the ambient temperature is too low, it will also cause the temperature of the battery module 41 to drop. When the temperature of the battery module 41 is too low, the activity of the substances inside the battery module 41 rapidly decreases, and the battery module 41 will self-discharge, causing the service life of the battery module 41 to rapidly decrease. At this time, the heating mode needs to be started (see Figure 3 , Figure 3 The dotted line in the figure is a heating circuit of the heat management unit 20, when the temperature sensor 16 senses that the temperature of the battery module 41 is lower than 20 DEG C, the control unit 30 sends a signal, and the refrigeration compressor 21 works, high-temperature and high-pressure refrigerant gas enters the evaporator 26 from the other end of the liquid collecting pipe 27 through the four-way valve 22, and is changed into refrigerant liquid by releasing heat, and then flows into the dry filter liquid accumulator 24 from one end of the liquid collecting pipe 27, and then enters the condenser 23, absorbs heat in the condenser 23, and is changed into low-temperature and low-pressure refrigerant gas, and finally flows back to the refrigeration compressor 21 through the four-way valve 22. When the battery temperature rises to 20 DEG C, the control unit 30 sends a signal, and the refrigeration compressor 21 stops working.

[0037] Please refer to Figure 4 In another embodiment of the utility model, the structure of the heat management unit 20 is basically the same as the above embodiment, the difference lies in that: the heat management unit 20 can be further provided with a throttling valve 25 between the dry filter liquid accumulator 24 and the liquid collecting pipe 27 of the evaporator 26 on the heating circuit.

[0038] In more detail, when it is necessary to start the heating mode (see Figure 4 ), Figure 4 The dotted line in the figure is the heating circuit of the heat management unit 20, when the temperature sensor 16 senses that the temperature of the battery module 41 is lower than 20℃, the control unit 30 sends a signal, the refrigeration compressor 21 works, high-temperature and high-pressure refrigerant gas enters the evaporator 26 from the other end of the liquid collecting pipe 27 through the four-way valve 22 and releases heat to become refrigerant liquid, flows into the dry filter liquid reservoir 24 from one end of the liquid collecting pipe 27, then enters the condenser 23 after throttling and pressure reduction through the throttling valve 25, absorbs heat in the condenser 23 to become low-temperature and low-pressure refrigerant gas, and finally flows back to the refrigeration compressor 21 through the four-way valve 22. When the battery temperature rises to 20℃, the control unit 30 sends a signal, the refrigeration compressor 21 stops working.

[0039] Please refer to Figure 5 , the control unit 30 includes a main controller 31 and an intelligent control module 32, the intelligent control module 32 detects the working condition of the battery unit 40 according to the safety unit 10 and feeds back the detection result to the intelligent control module 32, the intelligent control module 32 controls the heat management unit 20 to adjust the working condition of the battery unit 40, when the working condition of the battery unit 40 is abnormal, the intelligent control module 32 feeds back information to the main controller 31, and the main controller 31 controls the battery unit 40 to stop working.

[0040] More specifically, the control unit 30 detects the working condition of the battery module 41 through the temperature sensor 16 and the smoke sensor 15, and transmits the detected information to the intelligent control module 32. More specifically, when the temperature sensor 16 senses that the temperature is lower than the minimum temperature set by the battery module 41, the temperature sensor 16 transmits the temperature signal to the intelligent control module 32, and the intelligent control module 32 sends working instructions to the refrigeration compressor 21 and the four-way valve 22 through the internal setting program, and the thermal management unit 20 starts the heating mode work, and when the temperature of the battery module 41 rises to the set temperature, the thermal management unit 20 stops working, ensuring that the battery module 41 works at the appropriate temperature. When the temperature sensor 16 senses that the temperature is higher than the maximum temperature set by the battery module 41, the temperature sensor 16 transmits the temperature signal to the intelligent control module 32, and the intelligent control module 32 sends working instructions to the refrigeration compressor 21 and the four-way valve 22 through the internal setting program, and the thermal management unit 20 starts the refrigeration mode work, and the cold generated by the thermal management unit 20 is used to offset the heat dissipation of the battery module 41, ensuring that the battery module 41 works at the set temperature, thereby ensuring that the battery module 41 works at the best efficiency and the best life.

[0041] When the battery module 41 works abnormally, one of which is that the temperature of the battery module 41 rises abnormally, at this time, the temperature sensor 16 transmits the signal to the intelligent control module 32, and the intelligent control module 32 transmits the signal to the main controller 31, and the main controller 31 stops the battery unit 40 from working.
