Description

Technical Field

[0001] This application relates to the field of vehicle temperature management technology, and in particular to a vehicle cryogenic energy storage management system. Background Technology

[0002] In extremely cold environments, vehicles face various performance degradations and operational challenges. For example, engine oil has poor fluidity, and the resistance of moving parts increases significantly, leading to an increased load on the starting system. The chemical activity of the vehicle's battery decreases at low temperatures, resulting in a significant reduction in its energy storage capacity. Gasoline and diesel engines have poor atomization during cold starts, making starting difficult and increasing oil dilution. Internal combustion engines are more difficult to start, resulting in worse emissions, increased wear during cold starts, and a reduced service life.

[0003] To ensure vehicles can start normally in extremely cold environments, external heating or insulation materials are typically used to store heat, reducing the impact of low temperatures on engine starting. Some vehicles are equipped with engine preheating functions that automatically preheat the engine before starting, and also use engine oil with good low-temperature fluidity. However, in extremely cold environments, energy dissipates quickly, making it more difficult for the engine to warm up and start the vehicle quickly and promptly. Utility Model Content

[0020] This application provides a vehicle cryogenic energy storage management system that connects a heating device to the engine and the engine intake air filter to provide heat to the engine in extremely cold environments, thereby achieving the effect of quickly and timely starting the vehicle.

[0021] The following describes in detail, with reference to the accompanying drawings, a vehicle cryogenic energy storage management system provided in this embodiment. Figure 1 As shown, the vehicle low-temperature energy storage management system is communicatively connected to the vehicle's external temperature sensor 00. It includes: a heating device 10, an electronic water pump 20, a first flow control valve 30, an electronically controlled three-way valve 40, an engine intake air filter 50, and an engine 60. The first outlet 1a of the heating device 10 is connected to the electronic water pump 20, the electronic water pump 20 is connected to the first flow control valve 30, the first flow control valve 30 is connected to the inlet 4a of the electronically controlled three-way valve 40, the first outlet 4b of the electronically controlled three-way valve 40 is connected to the air inlet 5a of the engine intake air filter 50, and the air outlet 5b of the engine intake air filter 50 is connected to the water jacket inlet 6a of the engine 60 to form the intake system heating circuit.

[0022] The second outlet 4c of the electronically controlled three-way valve 40 is connected to the water jacket inlet 6a of the engine 60, and the water jacket outlet 6b of the engine 60 is connected to the first inlet 1b of the heating device 10 to form an engine heat pump heating circuit.

[0023] The heating device 10 includes an insulated container 11 and a heat exchange medium 12. The heat exchange medium 12 is stored in the insulated container 11 and is used for heat exchange with the engine 60 and the engine intake air filter 50. The heat exchange medium 12 is a high specific heat capacity liquid, which provides heat through the intake system heating circuit and the engine heat engine heating circuit, thereby raising the temperature of the engine 60 and the engine intake air filter 50. The insulated container 11 has a theoretical insulation effect of more than 96 hours, which can ensure the vehicle's effectiveness in low-temperature environments for 96 hours, solving the problem that vehicles cannot be started the next day after being left outdoors overnight in extremely cold regions.

[0024] The system operates as follows: When the vehicle power is turned on, the vehicle's external temperature sensor 00 begins detecting the ambient temperature. If the ambient temperature is higher than a first preset temperature (e.g., -5°C), the vehicle's low-temperature energy storage management system enters sleep mode. If the ambient temperature is lower than the preset temperature, the system is activated, continuously storing and heating the heat exchange medium 12. If the ambient temperature is higher than a second preset temperature (e.g., -10°C), the system enters sleep mode. If the ambient temperature is lower than the second preset temperature, the vehicle power switch is turned on, and the system begins heating. The first and second preset temperatures can be determined based on the local air temperature's influence on the vehicle. The heat exchange medium 12 enters the engine 60 or the engine intake air filter 50 via the electronic water pump 20 and the first flow control valve 30. Specifically, heat exchange medium 12 flows into the inlet 4a of the electronically controlled three-way valve 40 through the electronic water pump 20 and the first flow control valve 30. The first outlet 4b of the electronically controlled three-way valve 40 is open, and the second outlet 4c of the electronically controlled three-way valve 40 is closed. Heat exchange medium 12 flows into the engine intake air filter 50, providing heat to the engine intake air filter 50. After absorbing heat, the engine intake air filter 50 heats up and finally flows into the engine 60 to return to the insulation container 11. When the first outlet 4b of the electronically controlled three-way valve 40 is closed and the second outlet 4c of the electronically controlled three-way valve 40 is open, heat exchange medium 12 flows into the engine 60 through the water jacket inlet 6a, providing heat to the engine 60. After heat exchange, the engine 60 heats up and then flows back to the insulation container 11 through the water jacket outlet 6b of the engine 60 into the first inlet 1b of the heating device 10. When the vehicle temperature exceeds -10°C and starting is difficult, warming the engine (60) and / or the engine intake air filter (50) makes starting easier, thus improving the user experience. Furthermore, the heat exchange medium (12) alters the oil flow of the vehicle's engine in extremely cold environments, significantly reducing resistance to moving parts and protecting the starting system by reducing component wear by 50%.

[0025] As one possible implementation, the system also includes a vehicle power supply 70 and a second flow control valve 80; the second outlet 1c of the heating device 10 is connected to the second flow control valve 80, the second flow control valve 80 is connected to one end 7a of the vehicle power supply 70, and the other end 7b of the vehicle power supply 70 is connected to the first inlet 1b of the heating device 10, forming a power supply heating circuit. The heat exchange medium 12 enters the vehicle power supply 70 through the second flow control valve 80, provides heat to the vehicle power supply 70, and then flows back to the insulation container 11. The vehicle power supply 70 can be a battery. Under extremely cold conditions, the battery's storage capacity can be reduced by up to 70%. By raising the temperature, the battery's chemical activity increases, and simultaneously, the engine temperature rises, reducing the load on the starting system and thus lowering the battery's starting current.

[0026] To ensure that the heating device 10 can continuously provide heat to the engine 60 and the engine intake air filter 50, the system also includes a circuit or device for heating the heating device 10.

[0027] As one possible implementation, the heating device 10 also includes an externally powered electric heater 13, which is housed within the insulation container 11. The externally powered electric heater 13 is a 220V household power supply heating device with a maximum power of 3000W. In extremely cold environments, the externally powered electric heater 13 can be activated using a household power supply to heat the heat exchange medium 12. The heat exchange medium 12 flows into the intake system heating circuit and the engine hot-engine heating circuit to heat the vehicle, thus addressing the scenario of long-term vehicle parking.

[0028] As one possible implementation, the system also includes an engine exhaust pipe 90, a one-way valve 100, and a surrounding copper pipe 110. The surrounding copper pipe 110 is arranged around the surface of the engine exhaust pipe 90, and the section of the engine exhaust pipe located after the three-way catalytic converter and before the muffler is selected, as this section of the engine exhaust pipe generates the most heat. The third outlet 1d of the heating device 10 is connected to the one-way valve 100, which is connected to the surrounding copper pipe 110. The surrounding copper pipe 110 is connected to the second inlet 1e of the heating device 10, forming the heating circuit of the heating device. The surrounding copper pipe 110 is heated by the engine exhaust pipe 90, and the heat exchange medium 12 enters the surrounding copper pipe 110 through the one-way valve 100, where its temperature can be rapidly increased to 120°C. After being heated by the exhaust pipe, the heat exchange medium 12 flows into the insulation container 11 for storage. Heating is achieved using the waste heat of the engine exhaust pipe 90, eliminating the need for additional energy consumption.

[0029] As one possible implementation, the system also includes a first temperature sensor 120a, a second temperature sensor 120b, and a third temperature sensor 120c. The first temperature sensor 120a is installed on the engine intake air filter 50 to collect the temperature of the engine intake air filter 50. The second temperature sensor 120b is installed on the engine 60 to collect the temperature of the engine 60. The third temperature sensor 120c is installed on the vehicle power supply 70 to collect the temperature of the vehicle power supply 70. When the temperature is too low, the system is activated to heat it in time to prevent it from freezing.

[0030] In an embodiment of this application, a vehicle is also provided, including the aforementioned vehicle cryogenic energy storage management system.

[0031] Real-vehicle tests were conducted on the vehicle under different ambient temperatures. The combustion chamber temperatures of the engine under different ambient temperatures are shown in Table 1 below:

[0032] Ambient temperature (°C) -15-20 -20--25 -25-30 -30-40 24-hour residual temperature 115℃ 114℃ 112℃ 110℃ 48H residual temperature 110℃ 108℃ 104℃ 100℃ 72H residual temperature 105℃ 102℃ 94℃ 90℃ 96H residual temperature 100℃ 96℃ 86℃ 80℃

[0033] Table 1

[0034] As shown in Table 1, the temperature does not change much within 96 hours in the ambient temperature range of -15 to 20℃. Therefore, there will be no starting difficulties when the engine combustion chamber temperature is higher than -10℃. Vehicles equipped with a vehicle low-temperature energy storage management system are expected to be able to increase the temperature by 15-30℃.

[0035] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
