Description

Technical Field

[0002] In current household energy storage product systems (household energy storage products include photovoltaic panels, energy storage components, and hybrid inverters, where the photovoltaic panels are used to collect light energy, which is stored in the energy storage components via the hybrid inverter. Preferably, the energy storage components are lithium batteries; the electrical energy stored in the lithium batteries can be used in household appliances or incorporated into the power grid), when the electrical energy stored in the lithium batteries is supplied to household appliances, the lithium batteries generate a certain amount of heat. Existing heat dissipation solutions for lithium batteries have the following three methods and their shortcomings:

[0003] (1) Natural heat dissipation method: Although the system structure is simple and the installation and maintenance costs are low, the heat exchange capacity is poor and the ability to control temperature rise is weak.

[0004] (2) In the forced air cooling method, an axial flow fan and a simple air duct are set in the chassis module, but the environmental adaptability is poor and the heat dissipation effect is average.

[0005] (3) Liquid cooling systems with air conditioning have problems such as high system cost and large space occupation due to the presence of refrigeration equipment such as compressors and condensers.

[0006] In addition, the heat dissipation solution of the above-mentioned lithium battery only has a heat dissipation function, not a heating function; when the indoor temperature is too low, the temperature of the household energy storage product will also drop, which will cause the household energy storage product to be charged and discharged normally.

[0007] Therefore, there is an urgent need for an energy storage and heat dissipation system to solve the technical problems existing in the existing technology to a certain extent. Utility Model Content

[0056] Combine Figure 1 The present invention describes in detail an energy storage and heat dissipation system provided by the present application.

[0057] The present application provides an energy storage and heat dissipation system, comprising a battery module, a heat exchange component, and a switching component;

[0058] Specifically, the battery module includes a battery 13 and a hybrid inverter 14; wherein the battery 13 is provided with a plurality of cells, the plurality of cells are arranged in sequence, and a heat insulation plate can be provided between the cells for heat insulation; wherein the hybrid inverter 14 is electrically connected to the battery 13; further, in combination with Figure 2As shown, the hybrid inverter includes a converter, a bidirectional converter, a bus, a bidirectional inverter, a controller, a first switch K1 and a second switch K2; the two ends of the converter are electrically connected to the photovoltaic panel and the bus, respectively; the two ends of the bidirectional converter are electrically connected to the bus and the battery, respectively; one end of the bidirectional inverter is electrically connected to the bus, and the other end of the bidirectional inverter is electrically connected to the load through the second switch and to the grid through the first switch; the controller (preferably an MTTP controller) is electrically connected to the converter, the bidirectional converter, the bus, the bidirectional inverter, the first switch and the second switch, respectively.

[0059] During actual use, during daytime photovoltaic panel power generation, the controller first controls the bidirectional inverter to convert the direct current (DC) generated by the panels into alternating current (AC), closes the second switch, and opens the first switch to supply the power to the load. Secondly, for any excess power from the panels, the controller can optionally control the bidirectional converter to directly store the DC generated by the panels in the battery. Alternatively, the controller can control the bidirectional inverter to convert the DC generated by the panels into AC, close the first switch, and open the second switch to connect the power to the grid. Finally, battery energy storage can also be achieved through the following control process: the controller controls the first switch to close and the bidirectional inverter to convert the AC power from the grid into DC power for storage in the battery.

[0060] At night, the photovoltaic panels are not working, and the batteries and the power grid are working. First, the controller controls the bidirectional inverter to convert the DC power stored in the battery into AC power, and controls the second switch to close and the first switch to open, so that the power in the battery can be used for the load; secondly (when the battery power is insufficient), the controller controls both the first switch and the second switch to open, and the power grid directly supplies power to the load (the above-mentioned load can be understood as household appliances).

[0061] It is worth noting that a converter is installed between the photovoltaic module and the busbar, which can convert the low-voltage DC of the photovoltaic panel into high-voltage DC on the busbar; the energy storage battery ( Figure 2 A bidirectional converter is also provided between the energy storage battery (i.e., the storage battery in this application) and the busbar, which can convert the low-voltage DC of the energy storage battery and the high-voltage DC on the busbar into high-low voltage.

[0062] Therefore, by using the controller in the hybrid inverter, it is possible to control the input of photovoltaic energy, the charging / discharging of the battery, and the input / output of grid energy. This energy storage method is green and environmentally friendly.

[0063] Specifically, the heat exchange component has a heating unit and a cooling unit; the heating unit can heat the battery module so that the battery module is in a heating mode, which is suitable for when the temperature of the battery module is too low; the cooling unit can cool the battery module so that the battery module is in a cooling mode, which is suitable for when the temperature of the battery module is too high.

[0064] Specifically, the switching component can switch the temperature increasing unit or the temperature decreasing unit to operate, so as to increase or decrease the temperature of the battery module.

[0065] During actual use, the hand can touch the battery module to obtain the temperature of the battery module. According to experience, once the temperature is too high, the switching component can be manually executed to turn off the heating unit and turn on the cooling unit. The cooling unit is used to cool the battery module. Specifically, the cooling unit has a lower temperature, and the cooling unit is used to perform heat exchange with the battery module to reduce the temperature of the battery module. Once the temperature is too low, the switching component can be manually executed to turn off the cooling unit and start the heating unit. The heating unit is used to heat the battery module. Specifically, the heating unit has a higher temperature and performs heat exchange with the battery module to increase the temperature of the battery module.

[0066] In summary, the temperature of the battery module in the present application can be stably controlled, so that the battery module is within an appropriate operating temperature range. Specifically, the battery module can be cooled by the cooling unit, and the battery module can be heated by the heating unit. In actual use, the switching component can be used to select and switch according to actual needs, which is convenient for operation.

[0067] In this embodiment, the switching assembly includes a three-way valve.

[0068] Specifically, one end of the heating unit is connected to the first end 1 of the three-way valve through the first pipeline 4, and the second end of the heating unit is connected to the second end 2 of the three-way valve through the second pipeline 5, that is, when the first end 1 of the three-way valve is connected to the second end 2 of the three-way valve, the first pipeline 4 is connected to the second pipeline 5; when the heating unit is working, the heating unit can heat the medium in the first pipeline 4 and the second pipeline 5, so that the medium in the first pipeline 4 and the second pipeline 5 can be in a high temperature state.

[0069] Specifically, one end of the cooling unit is connected to the first pipeline 4 through the third pipeline 6, and the other end of the cooling unit is connected to the third end 3 of the three-way valve through the fourth pipeline 7; that is, when the first end 1 of the three-way valve is connected to the third end 3 of the three-way valve, the third pipeline 6, the first pipeline 4 and the fourth pipeline 7 are connected; when the cooling unit is working, the cooling unit can be used to cool the medium in the first pipeline 4, the third pipeline 6 and the fourth pipeline 7, so that the medium in the first pipeline 4, the third pipeline 6 and the fourth pipeline 7 can be kept in a low temperature state.

[0070] Specifically, the battery module is close to the first pipeline 4 , that is, the battery module and the first pipeline 4 can exchange heat, thereby ensuring that the battery 13 is in a suitable working state.

[0071] In summary, when the first end 1 of the three-way valve is connected to the second end 2 of the three-way valve, the cooling unit is off, and the heating unit is on, the first pipeline 4 containing the heat medium can exchange heat with the battery module with a low temperature, thereby increasing the temperature of the battery module, placing the battery module in a heating mode. When the first end 1 of the three-way valve is connected to the third end 3 of the three-way valve, the cooling unit is off. When the cooling unit is on, the first pipeline 4, the third pipeline 6, and the fourth pipeline 7 containing the low-temperature medium can exchange heat with the battery module with a high temperature, thereby decreasing the temperature of the battery 13, placing the battery module in a cooling mode.

[0072] More specifically, the temperature increasing unit includes a heater 10 ; one end of the heater 10 is connected to the first end 1 of the three-way valve through a first pipe 4 , and the other end of the heater 10 is connected to the second end 2 of the three-way valve through a second pipe 5 .

[0073] In order to ensure constant temperature heating, preferably, the heater 10 is a PTC heater 10, which has a constant temperature heating characteristic. Even in abnormal operation, due to the regulation of the PTC element itself, the input power can be reduced to a very low level, and no unexpected situation will occur.

[0074] In summary, when the first end 1 of the three-way valve is connected to the second end 2 of the three-way valve and the PTC heater 10 is turned on, the medium in the first pipeline 4 and the second pipeline 5 can be heated by the PTC heater 10 .

[0075] More specifically, the cooling unit includes a radiator 11 ; one end of the radiator 11 is connected to the first pipeline 4 through the third pipeline 6 , and the other end of the radiator 11 is connected to the third end 3 of the three-way valve through the fourth pipeline 7 .

[0076] Furthermore, the cooling unit further includes a fan 12 ; the fan 12 is close to the radiator 11 , and the fan 12 can increase the air circulation efficiency of the radiator 11 .

[0077] In summary, when the first end 1 of the three-way valve is connected to the third end 3 of the three-way valve, and the radiator 11 and the fan 12 are turned on, the radiator 11 and the fan 12 can be used to cool the medium in the first pipeline 4, the third pipeline 6 and the fourth pipeline 7.

[0078] In this embodiment, the household air-cooled water circulation heat dissipation device also includes a water cooling component; specifically, the water cooling component includes a water cooling plate 15, which is connected in series to the first pipeline 4; the battery module is close to the water cooling component and can exchange heat with the water cooling component.

[0079] In summary, when the battery module is in cooling mode, the three-way valve can be manually started so that the first end 1 of the three-way valve is connected to the third end 3 of the three-way valve. The high-temperature medium dissipates heat into the air in the radiator 11 and becomes a low-temperature medium. The low-temperature medium exchanges heat with the battery module in the water-cooled plate 15 to complete the cooling of the battery module, which can also be called circulating cooling.

[0080] In this embodiment, the energy storage and heat dissipation system further includes a water pump 16; the water pump 16 is disposed in the first pipeline 4; the three-way valve is a three-way solenoid valve; and the energy storage and heat dissipation system further includes a control unit.

[0081] Specifically, the control unit is communicatively connected to the battery 13, the water pump 16, the three-way solenoid valve, the heater 10, the radiator 11 and the fan 12;

[0082] More specifically, the control unit includes a temperature setting module, a temperature detection module and a temperature control module; the temperature setting module is communicated with the battery module and is used to set the temperature of the battery module; the temperature detection module is communicated with the battery module and the temperature control module respectively, and the temperature control module is communicated with the water pump 16, the heater 10 and the radiator 11 respectively.

[0083] In actual use, the temperature setting module first sets the temperature of the battery module; then the temperature detection module detects the detection temperature of the battery module in real time. When the detection temperature is higher than the set temperature, the signal is transmitted to the temperature control module. The temperature control module controls the first end of the three-way solenoid valve to conduct the second end of the three-way solenoid valve, and turns on the heater 10 and the water pump 16 to perform heat exchange between the battery module and the first pipeline 4, so that the battery module is heated and in the heating mode; when the detection temperature is lower than the set temperature, the signal is transmitted to the temperature control module, and the temperature control module controls ... conduct the heat exchange between the battery module and the first pipeline 4, so that the battery module is heated and in the heating mode. The first end of the solenoid valve is connected to the third end of the three-way solenoid valve, and the radiator 11 and the fan 12 are turned on to perform heat exchange between the battery module and the first pipeline 4, so that the battery module is cooled and is in cooling mode; when the temperature difference between the battery cells in the battery 13 is large, the temperature control module can control the water pump 16 to start, and the first end of the three-way solenoid valve is connected to the third end of the three-way solenoid valve, and the radiator 11 is turned off. The medium in the first pipeline 4, the third pipeline 6 and the fourth pipeline 7 is self-circulated, and the water cooling plate 15 exchanges heat with the battery 13, thereby controlling the temperature difference between the battery cells to be within an appropriate range.

[0084] In summary, the temperature of the battery module in the present application can be stably controlled, so that the battery module is within an appropriate operating temperature range. Specifically, the battery module can be cooled by the cooling unit, and the battery module can be heated by the heating unit. In actual use, the switching component can be used to select and switch according to actual needs, which is convenient for operation.

[0085] In addition, the temperature between the battery cells can be controlled at a constant temperature, realizing intelligent water temperature control under all working conditions.

The energy storage and heat dissipation system also includes a first shell 18 and a second shell 20. The first shell 18 and the second shell 20 are welded together. The first shell and the second shell both have end covers 19. The hybrid inverter, battery and water cooling plate are integrated in the first shell, the heater, water pump, radiator and fan are integrated in the second shell, and the water tank 17 is connected to the water pump.

[0087] In addition, the energy storage and heat dissipation system provided in this application adopts an air cooling form that combines a radiator and a fan, which is more energy-efficient.
