Currently, energy storage technology has entered the stage of large-scale commercial application, and energy storage technologies in different application scenarios are developing rapidly. The application of energy storage systems in power systems is also becoming increasingly widespread.

[0003] However, existing energy storage technologies face numerous unresolved issues. Regarding the operation of energy storage devices, common devices such as lithium batteries and supercapacitors generate significant amounts of heat during operation. If this heat cannot be dissipated promptly, the device temperature will continue to rise, affecting not only the performance and lifespan of the energy storage equipment but also potentially posing serious safety hazards and threatening the stable operation of the entire energy storage system.

[0048] This embodiment provides an electronic control system with a high protection level, improving the sealing performance and safety performance of the electronic control system.

[0049] like Figures 1-3 As shown, the electronic control system mainly includes a housing 10, which integrates a compressor drive circuit board 11, a water pump drive circuit board 12, a fan drive circuit board 13, a PTC contactor 14, a heating element relay 15, a liquid replenishment relay 16, an auxiliary power supply 17, a power battery thermal management controller 18, a three-phase incoming circuit breaker 19, and a local touch screen 20. The electronic control system also includes a compressor connector 30, a PTC connector 40, a water pump connector 50, a fan connector 60, and a heating element connector 70. The housing 10 has a first end face 101 and a second end face 102 facing each other. The first end face 101 has a first mounting hole and a second mounting hole. The compressor connector 30 is installed in the first mounting hole and electrically connected to the compressor drive circuit board 11. The PTC connector 40 is installed in the second mounting hole and electrically connected to the PTC contactor 14. The second end face 102 has a third mounting hole, a fourth mounting hole and a fifth mounting hole. The water pump connector 50 is installed in the third mounting hole and electrically connected to the water pump drive circuit board 12. The fan connector 60 is installed in the fourth mounting hole and electrically connected to the fan drive circuit board 13. The heating belt connector 70 is installed in the fifth mounting hole and electrically connected to the heating belt relay 15.

[0050] Based on the above design, in this embodiment, by integrating the ten major electrical components—compressor drive circuit board 11, water pump drive circuit board 12, fan drive circuit board 13, PTC contactor 14, heating belt relay 15, liquid replenishment relay 16, auxiliary power supply 17, power battery thermal management controller 18, three-phase incoming circuit breaker 19, and local touch screen 20—into the enclosure 10, not only is the integration of the electrical control system improved, but also, since the ten major electrical components are all located inside the enclosure 10, the enclosure 10 acts as a barrier to provide a certain degree of shielding and protection for the electrical components. This enables the system to cope with harsh weather conditions such as rain, snow, wind, and sand, improves the sealing performance and safety performance of the electrical control system, and ensures the stable operation of the unit.

[0051] Furthermore, in this embodiment, by providing a compressor connector 30, a PTC connector 40, a water pump connector 50, a fan connector 60, and a heating element connector 70, the electrical components inside the enclosure 10 can be effectively electrically connected to equipment outside the enclosure 10 through the aforementioned connectors (including the compressor connector 30, PTC connector 40, water pump connector 50, fan connector 60, and heating element connector 70) while ensuring that the electrical control system has a high protection level.

[0052] In this embodiment, the compressor connector 30, PTC connector 40, water pump connector 50, fan connector 60, and heating belt connector 70 all have an IP67 protection rating (including dustproof and waterproof).

[0053] In this embodiment, the three-phase incoming circuit breaker 19 is connected to the main power line and monitors current anomalies in real time through a built-in thermomagnetic tripping mechanism. When an overload or short circuit is detected, the three-phase incoming circuit breaker 19 can disconnect the circuit within milliseconds.

[0054] In this embodiment, the auxiliary power supply 17 is used to provide auxiliary power to the compressor drive circuit board 11, water pump drive circuit board 12, fan drive circuit board 13, PTC contactor 14, heating belt relay 15, liquid replenishment relay 16, auxiliary power supply 17, and power battery thermal management controller 18 when the three-phase incoming circuit breaker 19 cuts off the circuit, so as to ensure that the electronic control system can continue to work normally.

[0055] The electrical control system in this embodiment also includes a compressor, a PTC heater, a water pump, a fan, and a heating belt. The end of the compressor connector 30 facing away from the compressor drive circuit board 11 is electrically connected to the compressor, so that the compressor drive circuit board 11 can control the compressor. For example, it can precisely adjust the operating frequency and load of the compressor according to parameters such as indoor and outdoor ambient temperature and set temperature.

[0056] The end of the PTC connector 40 opposite to the PTC contactor 14 is electrically connected to the PTC heater, thereby enabling the PTC contactor 14 to control the operating state of the PTC heater.

[0057] The end of the water pump connector 50 that is away from the water pump drive circuit board 12 is electrically connected to the water pump, thereby enabling the water pump drive circuit board 12 to control the working state of the water pump.

[0058] The end of the fan connector 60 facing away from the fan drive circuit board 13 is electrically connected to the fan, thereby enabling the fan drive circuit board 13 to control the working state of the fan.

[0059] The end of the heating strip connector 70 opposite to the heating strip relay 15 is electrically connected to the heating strip, thereby enabling the heating strip relay 15 to control the working state of the heating strip. Specifically, the heating strip can be wrapped around the fuel tank or fuel line of the car. The heating strip uses electrical energy to heat the fuel tank or fuel line, reducing the viscosity of the fuel and ensuring that the fuel flows quickly to the lubrication or combustion system, thus improving the success rate of cold starts.

[0060] Optionally, in this embodiment, there are multiple water pump connectors 50 and multiple fan connectors 60. One water pump connector 50 is electrically connected to one water pump, and one fan connector 60 is electrically connected to one fan. There are multiple third and fourth mounting holes. One water pump connector 50 is installed in one third mounting hole, and one fan connector 60 is installed in one fourth mounting hole.

[0061] For example, in this embodiment, the third mounting hole, the fourth mounting hole, the water pump connector 50, the fan connector 60, the water pump, and the fan are all provided in pairs. In this way, when one water pump or one fan fails, the other water pump or fan can operate normally, thereby improving the reliability of the electrical control system.

[0062] like Figures 2-3 As shown, the second end face 102 in this embodiment is also provided with an external communication connector 80. The external communication connector 80 enables the electronic control system to interact with other devices or a control center. For example, the external communication connector 80 connects to a host computer, monitoring platform, or external sensors to achieve real-time data exchange. For instance, the external communication connector 80 can upload temperature and voltage data from the electronic control system to a cloud management system, and simultaneously receive remote start / stop commands, etc.

[0063] like Figures 1-2As shown, in this embodiment, a filter board 21 is also provided inside the housing 10. The filter board 21 is electrically connected to the compressor drive circuit board 11, the water pump drive circuit board 12, and the fan drive circuit board 13. This can absorb the current surge generated when the compressor, water pump, and fan start and stop, avoiding impact on other circuits, thereby improving the protection of electronic components (chips, sensors) in other circuits.

[0064] In this embodiment, an insulating gasket is provided between the filter board 21 and the housing 10. The insulating gasket is configured to prevent interference from the grounding loop. The insulating gasket enables electrical isolation between the filter board 21 and the housing 10.

[0065] In this embodiment, the housing 10 also has a third end face (not shown in the figure), with an opening provided on the third end face, and the touch area of ​​the local touch screen 20 is embedded in the opening. This allows operators to flexibly control the operating status of other electrical components in the electrical control system through the touch area of ​​the local touch screen 20, while ensuring that the housing 10 has a high level of sealing and protection.

[0066] like Figure 3 As shown, the enclosure 10 also has a fourth end face 103, which is directly opposite to the third end face. Multiple sets of heat dissipation fins 1031 are provided on the fourth end face 103, which can improve the heat dissipation efficiency of the enclosure 10 and improve safety performance.

[0067] Furthermore, a forced air-cooled fan can be added to the fourth end face 103 in this embodiment to further improve the heat dissipation efficiency of the housing 10.

[0068] like Figures 1-3 As shown, in this embodiment, handles 1011 are provided on both the first end face 101 and the second end face 102, and the two handles 1011 are symmetrically arranged about the axis of the housing 10. The handles 1011 facilitate the lifting of the housing 10 by operators when installing or maintaining the electrical control system, thereby improving work efficiency.

[0069] This embodiment also provides an energy storage thermal management unit, which includes a frame and the aforementioned electrical control system. The electrical control system includes a housing 10, which is detachably connected to the frame. Specifically, the housing 10 can be detachably connected to the frame using screws or bolts, facilitating subsequent maintenance and disassembly of the housing 10.

[0070] Because the energy storage thermal management unit includes the aforementioned electrical control system, it has a high degree of integration and protection level, which improves safety performance.

[0071] Obviously, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention.
