The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0039] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0040] In the following description, the terms "first, second, and third" are used merely as examples to distinguish between different objects and do not represent a specific order or precedence for the objects. It is understood that the specific order or precedence of "first, second, and third" can be interchanged where permitted, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing the embodiments of this application only and are not intended to limit this application.

[0042] Embodiments of the present application provide a vehicle energy control system, method, apparatus, device, vehicle, storage medium, and program product.

[0043] Below, various embodiments of the vehicle energy control system, method, device, equipment, vehicle, storage medium and program product provided in the embodiments of the present application are described.

[0044] In a first aspect, an embodiment of the present application provides an energy control system for a vehicle.

[0045] refer to Figure 1The vehicle energy control system 10 shown in the figure includes an energy storage tank 101, an energy controller 102, and a data acquisition sensor 103. The data acquisition sensor 103 is connected to the energy controller 102, which is in turn connected to the energy storage tank 101. The energy storage tank 101 is used to store coolant; the data acquisition sensor 103 is used to collect vehicle status information and transmit this information to the energy controller 102; the energy controller 102 is used to determine the target energy storage mode of the energy storage tank 101 based on the status information; and based on the target energy storage mode, it controls the coolant in the energy storage tank 101 to provide the required energy to the vehicle; the target energy storage mode is used to indicate the type of energy required by the vehicle.

[0046] The energy storage tank 101 is used to store coolant.

[0047] The embodiment of the present application does not limit the type of coolant, and can be configured according to actual needs. For example, the coolant can be water or other liquids.

[0048] The present embodiment does not limit the structure, material, size, or placement of the energy storage tank 101, and can be configured based on actual needs. For example, the energy storage tank 101 can be made of a material with thermal insulation properties. The structure of the energy storage tank can be configured based on the vehicle's space requirements. For example, the energy storage tank 101 can be cylindrical, rectangular, spherical, or other shapes. Of course, the energy storage tank 101 can also be designed with an irregular structure based on space requirements.

[0049] The size, i.e., capacity, of the energy storage tank 101 can be configured based on actual needs. For example, the actual energy demand of a certain type of vehicle during use can be counted, and a reasonable capacity of the energy storage tank 101 can be configured based on the energy demand.

[0050] The location of the energy storage tank 101 can be determined based on the locations of the components in the vehicle that require energy and the components that can provide energy. The closer the energy storage tank 101 is to these components, the fewer pipes there are, the more space is saved, and the faster the energy demand response is, the better the user experience.

[0051] Regarding the data acquisition sensor 103 : it is used to collect the vehicle's state perception information and send the state perception information to the energy controller 102 .

[0052] The data acquisition sensor here may be one or more sensors. The state perception information corresponds to the information collected by one or more sensors.

[0053] For example, the data acquisition sensor may include one or more of the following: a position sensor, a temperature sensor, and a light sensor. The corresponding state perception information may include, but is not limited to, one or more of the following: the vehicle's position, ambient temperature, and ambient light.

[0054] The energy controller 102 is used to determine the target energy storage mode of the energy storage tank 101 based on the state perception information; and control the coolant in the energy storage tank 101 based on the target energy storage mode to provide the required energy to the vehicle.

[0055] The target energy storage mode is used to indicate the type of energy required by the vehicle. For example, the target energy storage mode may indicate that the energy required by the vehicle is thermal energy. Alternatively, the target energy storage mode may indicate that the energy required by the vehicle is cooling energy.

[0056] Based on the state perception information, the energy controller can know the type of energy required by the vehicle in the current environment, thereby determining the target energy storage mode, and controlling the energy storage tank to store and provide energy (coolant) according to the target energy storage mode, thereby providing the required energy to the vehicle.

[0057] For example, based on the state perception information, it is determined that the vehicle is currently in winter, and the energy required by the vehicle is determined to be thermal energy, so the energy storage tank is controlled to store thermal energy, that is, hot coolant; the stored hot coolant is used to provide the required thermal energy to the vehicle.

[0058] For another example, based on the state perception information, it is determined that the vehicle is currently in summer, and the energy required by the vehicle is determined to be cold energy, so the energy storage tank is controlled to store cold energy, that is, cold coolant; the stored cold coolant is used to provide the required cold energy to the vehicle.

[0059] The embodiment of the present application does not limit the type of energy controller 102, and it can be configured according to actual needs. For example, the energy controller 102 can be a newly added controller; or the energy controller 102 can be implemented by reusing other controllers.

[0060] The vehicle energy control system provided in this embodiment includes an energy storage tank, an energy controller, and a data acquisition sensor; the data acquisition sensor is connected to the energy controller, and the energy controller is connected to the energy storage tank; the energy storage tank is used to store coolant; the data acquisition sensor is used to collect vehicle status perception information and send the status perception information to the energy controller; the energy controller is used to determine a target energy storage mode for the energy storage tank based on the status perception information; and based on the target energy storage mode, controls the coolant in the energy storage tank to provide the required energy to the vehicle; the target energy storage mode is used to indicate the type of energy required by the vehicle.

[0061] The vehicle's energy control solution incorporates an energy storage tank, an energy storage controller, and data acquisition sensors. The energy storage controller determines the type of energy required by the vehicle based on vehicle status information collected by the data acquisition sensors, thereby determining the target storage mode for the energy storage tank. The energy storage tank then stores energy according to the target storage mode and supplies the stored energy to the vehicle. This allows for the storage and application of excess energy, improving energy utilization. Furthermore, storing and applying energy according to the target storage mode quickly meets the vehicle's energy needs, enhancing the user experience. Furthermore, the vehicle's excess energy can be centrally stored and managed, improving management efficiency.

[0062] Next, the energy storage of the energy storage tank will be described.

[0063] The target energy storage mode includes a first energy storage mode or a second energy storage mode.

[0064] In the first energy storage mode, the energy storage tank 101 is used to store coolant in a first temperature range to store thermal energy; in the first storage mode, the energy required by the vehicle is thermal energy;

[0065] In the second storage mode, the energy storage tank 101 is used to store coolant in the second temperature range to store cold energy; in the second storage mode, the energy required by the vehicle is cold energy, and the temperature value in the first temperature range is greater than the temperature value in the second temperature range.

[0066] The embodiment of the present application does not limit the values of the first temperature range and the second temperature range, and can be configured according to actual needs.

[0067] For example, the first temperature range may be 80 degrees Celsius (°C) to 100°C; the second temperature range may be -20°C to 5°C.

[0068] The vehicle's energy controller controls the opening and closing of the passage flowing into the energy storage tank and the opening and closing of the passage flowing out of the energy storage tank to achieve the replacement, storage, inflow and outflow of the coolant.

[0069] In this embodiment, the vehicle's demand for thermal energy can be met based on the first energy storage mode, and the vehicle's demand for cold energy can be met based on the second energy storage mode, that is, various energy demand scenarios can be met.

[0070] The structure of the energy storage tank 101 is described below.

[0071] In one possible implementation, reference Figure 2 As shown, the energy storage tank 101 includes an inner insulation layer 1011 and a heat-resistant outer shell 1012; there is a gap 1013 between the inner insulation layer and the heat-resistant outer shell; the gap 1013 is in a vacuum state or filled with an inert gas.

[0072] The present embodiment of the application does not limit the material of the inner insulation layer 1011 and can be configured according to actual needs. For example, the inner insulation layer 1011 can be made of a stainless steel liner. The present embodiment of the application also does not limit the material of the heat-resistant outer shell 1012 and can be configured according to actual needs. For example, the heat-resistant outer shell 1012 can be made of stainless steel.

[0073] In this embodiment, the energy storage tank 101 can achieve heat preservation of the coolant through the insulation layer, thereby reducing the temperature, that is, the exchange of energy, and can reduce the heat exchange with the external environment through the heat-resistant shell. The heat exchange can be further reduced through the gap, thereby improving the effectiveness of the energy of the stored coolant.

[0074] It is understandable that the energy storage tank 101 may be provided with other structures according to actual needs, such as a handle for easy movement, an inlet, an outlet, a protective film, etc., which will not be described in detail here.

[0075] Next, the data collection sensor 103 will be described.

[0076] In one possible implementation, reference Figure 3 As shown in the figure, the data acquisition sensor 103 includes: a position sensor 1031, a temperature sensor 1032 and a photosensor 1033; the position sensor 1031, the temperature sensor 1032 and the photosensor 1033 are connected to the energy controller 102 respectively.

[0077] The position sensor 1031 is used to collect the position of the vehicle and send the position to the energy controller 102.

[0078] The position of a vehicle refers to the location of the vehicle.

[0079] The temperature sensor 1032 is used to collect the ambient temperature of the vehicle and send the ambient temperature to the energy controller 102.

[0080] The ambient temperature of the vehicle may include, but is not limited to, one or more of the following: the temperature inside the vehicle and the temperature outside the vehicle.

[0081] The photosensor 1033 is used to collect the ambient light of the vehicle and send the ambient light to the energy controller 102 .

[0082] The ambient light of the vehicle may include but is not limited to one or more of the following: light inside the vehicle and light outside the vehicle.

[0083] The present embodiment does not limit the types of position sensor 1031, temperature sensor 1032, and light sensor 1033, and they can be configured according to actual needs. The position sensor 1031, temperature sensor 1032, and light sensor 1033 can be newly added sensors or sensors reused from other systems.

[0084] In this embodiment, the data acquisition sensors include three types of sensors, which can collect rich state perception information, improve the accuracy of the target energy storage mode, and enhance the vehicle-using experience.

[0085] In a second aspect, embodiments of the present application provide a vehicle energy control method, which can be implemented by the aforementioned energy controller, or an energy control system including an energy controller, an electronic device, a vehicle, etc. The following description will take a vehicle as an example.

[0086] refer to Figure 4 The process may include but is not limited to the following S401 to S403.

[0087] S401: The vehicle obtains vehicle status perception information.

[0088] Vehicle state perception information is used to assist in determining the type of energy required by the vehicle. Therefore, vehicle state perception information is information related to the type of energy required by the vehicle. For example, vehicle state perception information may include one or more of the following: vehicle location, vehicle ambient temperature, and vehicle ambient light.

[0089] The data acquisition sensors in the vehicle will collect the vehicle's status perception information in real time, and the vehicle directly reads the status perception information collected by the data collector.

[0090] S402: The vehicle determines a target energy storage mode of the vehicle's energy storage tank based on the state perception information.

[0091] The target energy storage mode is used to indicate the type of energy required by the vehicle.

[0092] The vehicle determines the type of energy required by the vehicle based on the state perception information, and then determines the target energy storage mode of the energy storage tank based on the type of energy required by the vehicle.

[0093] S403: The vehicle controls the coolant in the energy storage tank based on the target energy storage mode to provide the required energy to the vehicle.

[0094] The vehicle controls the flow, storage, and outflow of coolant in the energy storage tank based on the target storage mode to provide the required energy to the vehicle.

[0095] The vehicle energy control method provided in an embodiment of the present application may include: obtaining state perception information of the vehicle; determining a target energy storage mode of the vehicle's energy storage tank based on the state perception information; the target energy storage mode is used to indicate the type of energy required by the vehicle; and controlling the coolant in the energy storage tank based on the target energy storage mode to provide the required energy to the vehicle.

[0096] This method can determine the type of energy required by the vehicle based on the vehicle's state perception information collected by data acquisition sensors, thereby determining the target storage mode of the energy storage tank. The energy storage tank then stores energy according to the target storage mode and provides the stored energy to the vehicle. This, on the one hand, allows excess energy to be stored and applied, improving energy utilization; on the other hand, storing and applying energy according to the target storage mode can quickly meet the vehicle's energy needs and improve the driving experience; and, yet another, the vehicle's excess energy can be uniformly stored and applied, improving management efficiency.

[0097] Next, the process of controlling the coolant in the energy storage tank based on the target energy storage mode in S403 to provide the required energy to the vehicle is described.

[0098] This process may include but is not limited to the following case 1 or case 2.

[0099] Case 1: When the target energy storage mode is the first energy storage mode, how to control the coolant in the energy storage tank?

[0100] Case 2: When the target energy storage mode is the second energy storage mode, how to control the coolant in the energy storage tank.

[0101] Next, a process of controlling the coolant in the energy storage tank in case 1 when the target energy storage mode is the first energy storage mode is described.

[0102] refer to Figure 5 The process may include but is not limited to the following S501 and S502.

[0103] The energy required by the vehicle in the first storage mode is thermal energy.

[0104] S501: If a first condition is met, control the coolant in the first temperature range in the thermal energy providing component of the vehicle to flow into the energy storage tank for storage.

[0105] The first condition is used to indicate that the heat supply component has excess heat energy. The embodiment of the present application does not limit the first condition and the heat supply component, and can be configured according to actual needs.

[0106] Example 1: When the heat energy providing component includes an engine or a range extender, the first condition may include: the engine or the range extender is in operation and the water temperature reaches 80° C. or above, and the radiator will execute the cooling instruction.

[0107] S501 can be implemented as follows: determining whether a first condition is met; if it is determined that the first condition is met, controlling to open a control valve between the thermal energy supply component of the vehicle and the energy storage tank, so that coolant in a first temperature range in the thermal energy supply component flows into the energy storage tank for storage; and simultaneously opening a control valve between the energy storage tank and other components, so that coolant originally in the energy storage tank, which is lower than the first temperature range, is discharged; and then the coolant at the first temperature range that has flowed into the energy storage tank is stored.

[0108] The receiving assembly for the coolant discharged from the energy storage tank is not limited and can be configured according to actual needs. The receiving assembly may or may not be a heat energy providing assembly. Based on Example 1, the coolant in the energy storage tank that is below the first temperature can be discharged to the engine or range extender to cool the engine or range extender.

[0109] The energy management circuits in the embodiments of the present application are all coolant circulation circuits. Each component in the vehicle has a coolant circulation circuit.

[0110] S502: If the second condition is met, control the coolant in the first temperature range in the energy storage tank to flow out to the thermal energy demanding component of the vehicle.

[0111] The second condition is used to indicate that the heat energy demanding component has heat energy demand. The embodiment of the present application does not limit the second condition and the heat energy demanding component, and can be configured according to actual needs.

[0112] Example 2: When the heat demand component includes a cabin heating component, the second condition may include: turning on the heating switch. When the heat demand component includes a battery insulation component, the second condition may include: the temperature of the battery insulation component is lower than a temperature threshold.

[0113] S502 may be implemented as follows: determining whether a second condition is satisfied; if so, opening a control valve between the vehicle's thermal energy demand component and the energy storage tank to allow coolant within the first temperature range in the energy storage tank to flow to the vehicle's thermal energy demand component. A control valve between the energy storage tank and the inflow component may also be simultaneously opened to allow coolant from the inflow component to flow into the energy storage tank.

[0114] The inflow component in the energy storage tank is not limited here and can be configured according to actual needs. The inflow component here can be a heat energy demand component or not. Based on Example 2, the coolant in the battery insulation component, which is below the first temperature range, can be directly flowed into the energy storage tank.

[0115] In this embodiment, when the heat energy providing component has excess heat energy, the excess heat energy can be stored in the energy storage tank, thereby directly reducing the cooling demand of the heat energy providing component, and the heat energy stored in the energy storage tank (coolant in the first temperature range) can provide heat energy to the heat energy demanding component in a timely manner when the heat energy demanding component has heat energy demand, with a fast response speed, reasonable energy distribution, and low heat energy waste.

[0116] Next, a process of controlling the coolant in the energy storage tank in case 2 when the target energy storage mode is the second energy storage mode is described.

[0117] refer to Figure 6 The process may include but is not limited to the following S601 and S602.

[0118] The energy required by the vehicle in the second storage mode is cold energy.

[0119] S601: If the third condition is met, control the coolant in the second temperature range in the cold energy providing component of the vehicle to flow into the energy storage tank for storage.

[0120] The third condition is used to indicate that the cold energy providing component has the ability to provide cold energy. The present embodiment does not limit the third condition and the cold energy providing component, and can be configured according to actual needs.

[0121] In Example 3, when the cooling energy providing component includes an air conditioner compressor component or an air conditioner evaporator component, the third condition may include: the air conditioner compressor component or the air conditioner evaporator component is in an operating state and the load of the air conditioner compressor component or the air conditioner evaporator component is less than a load threshold. For example, the air conditioner compressor component or the air conditioner evaporator is in a low-load operating state.

[0122] S601 can be implemented as follows: determining whether the third condition is met; if it is determined that the third condition is met, controlling to open a control valve between the cold energy supply component and the energy storage tank of the vehicle, so that the coolant in the second temperature range in the cold energy supply component flows into the energy storage tank for storage; and simultaneously opening a control valve between the energy storage tank and other components, so that the coolant originally in the energy storage tank, which is higher than the second temperature range, is discharged; and then the coolant in the second temperature range that has flowed into the energy storage tank is stored in the energy storage tank.

[0123] There is no limitation on the receiving assembly after the coolant in the energy storage tank is discharged, and it can be configured according to actual needs.

[0124] The energy management circuits in the embodiments of the present application are all coolant circulation circuits. Each component in the vehicle has a coolant circulation circuit.

[0125] A coolant pipe may be added around the air conditioner compressor assembly or air conditioner evaporator. Energy from the air conditioner compressor assembly or air conditioner evaporator can be transferred to the surrounding coolant pipe, which then flows coolant in the second temperature range into the energy storage tank.

[0126] S602: If the fourth condition is met, control the coolant in the second temperature range in the energy storage tank to flow out to the cooling energy demanding component of the vehicle.

[0127] The temperature value in the first temperature range is greater than the temperature value in the second temperature range.

[0128] The fourth condition is used to indicate that the cooling energy demanding component has cooling energy demand. The present embodiment does not limit the fourth condition and the cooling energy demanding component, and can be configured according to actual needs.

[0129] Example 4: When the cooling energy demanding component includes an electric drive heat dissipation component, the fourth condition may include: the temperature of the electric drive heat dissipation component is greater than a temperature threshold.

[0130] S602 may be implemented as follows: determining whether a fourth condition is satisfied; if so, opening a control valve between the vehicle's cooling energy demanding component and the energy storage tank to allow coolant in the second temperature range in the energy storage tank to flow to the vehicle's cooling energy demanding component. A control valve between the energy storage tank and the inflow component may also be opened simultaneously to allow coolant in the inflow component to flow into the energy storage tank.

[0131] There is no limitation on the inflow components in the energy storage tank, which can be configured according to actual needs.

[0132] In this embodiment, when the cold energy providing component is under low load, the cold energy providing component can provide more cold energy and store part of the cold energy in the energy storage tank. When the cold energy demanding component has a cold energy demand, cold energy can be provided to the cold energy demanding component in a timely manner. The response speed is fast, the energy distribution is reasonable, and the waste of cold energy is low.

[0133] The following describes the heat supply component, the heat demand component, the cold supply component, and the cold demand component.

[0134] The heat energy providing components include one or more of the following: super charging components or fast charging components, power battery components, engine components or range extender components, motor components, and air conditioning components;

[0135] Thermal energy demand components include one or more of the following: cabin heating components, seat heating components, battery insulation components, electric drive insulation components, battery control insulation components, electronic control unit insulation components,

[0136] The cold energy providing components include one or more of the following: an air conditioner evaporator component, an air conditioner compressor component;

[0137] Cold energy demand components include one or more of the following: fast charging or super charging high-voltage wiring harness components, battery components, charging heat exchange components, electric drive heat dissipation components, motor controller thermal interaction components, air conditioning defogger and defrost components, cabin cooling components, battery discharge or electric drive cooling heat exchange components.

[0138] Heat supply components, heat demand components, cooling supply components, and cooling demand components can be configured according to actual needs, offering flexibility and wide application. This allows all three components to be controlled and managed uniformly through the energy controller, resulting in higher management efficiency.

[0139] Next, the process of determining the target energy storage mode of the energy storage tank of the vehicle based on the state perception information in S402 is described.

[0140] This process may include but is not limited to any one of the following methods 1 to 3.

[0141] Method 1: Determine the target energy storage mode when the state perception information includes the vehicle's location;

[0142] Method 2: Determine the target energy storage mode when the state perception information includes the vehicle's location and ambient temperature;

[0143] Method 3: Determine the target energy storage mode when the state perception information includes the vehicle's position, ambient temperature, and ambient light.

[0144] Next, the process of determining the target energy storage mode in method 1 when the state perception information includes the position of the vehicle is described.

[0145] refer to Figure 7 The process may include but is not limited to the following S701 and S702.

[0146] S701. The vehicle determines the weather information and season of the vehicle's location based on the location.

[0147] Based on the vehicle's location, the vehicle can access a weather application to read the weather information for that location. This weather information can be a forecast for the next period of time. The forecast information may include, but is not limited to, temperature, whether there will be rain or snow, and so on.

[0148] The vehicle can determine the season based on the current time.

[0149] S702: The vehicle determines a target energy storage mode based on season and weather information.

[0150] The vehicle combines seasonal and weather information to determine the target energy storage mode.

[0151] In one possible implementation, if the season is winter and the temperature in the weather information is less than a temperature threshold, the target energy storage mode is determined to be the first energy storage mode. If the season is winter but the temperature in the weather information is greater than the temperature threshold, the target energy storage mode is determined to be the second energy storage mode. For example, in a tropical winter, the temperature in the weather information is high, and in this case, cold energy should be stored rather than heat energy.

[0152] In another possible implementation, if the season is summer and the temperature in the weather information is greater than a temperature threshold, the target energy storage mode is determined to be the second energy storage mode. If the season is summer but the temperature in the weather information is less than the temperature threshold, the target energy storage mode is determined to be the first energy storage mode. For example, in the summer in cold regions (such as Antarctica), the temperature in the weather information is low, and in this case, thermal energy should be stored rather than cold energy.

[0153] In this embodiment, determining the target energy storage mode in combination with season and weather information will be more in line with actual needs.

[0154] Next, the process of determining the target energy storage mode in the second method when the state perception information includes the vehicle's position and ambient temperature is described.

[0155] refer to Figure 8 The process may include but is not limited to the following S801 to S803.

[0156] S801. The vehicle determines the weather information and season of the vehicle's location based on the location.

[0157] The implementation of S801 may refer to the detailed description of the vehicle determining the weather information and season at the vehicle's location based on the location in S701, which will not be repeated here.

[0158] S802: The vehicle determines an initial energy storage mode based on season and weather information.

[0159] The implementation of S802 may refer to the detailed description of the vehicle determining the target energy storage mode based on season and weather information in S702, which will not be described in detail here.

[0160] The difference is that here the target energy storage mode determined in S702 is used only as the initial energy storage mode.

[0161] S803: The vehicle adjusts the initial energy storage mode based on the ambient temperature to determine the target energy storage mode.

[0162] The target energy storage mode can also be determined based solely on the ambient temperature. For example, if the ambient temperature is below a threshold, it is determined that there is a demand for heat energy, and the target energy storage mode is determined to be the first energy storage mode. For example, if the ambient temperature is above a threshold, it is determined that there is a demand for cooling energy, and the target energy storage mode is determined to be the second energy storage mode.

[0163] In one possible implementation, if the season is winter and the temperature in the weather information is less than a temperature threshold, the initial energy storage mode is determined to be the first energy storage mode. Even if the ambient temperature is higher than the ambient temperature threshold, the target energy storage mode is determined to be the first energy storage mode. For example, in winter, even if the current temperature is high, it generally lasts for a short time, and the actual demand is still thermal energy.

[0164] In another possible implementation, if the season is summer and the temperature in the weather information is greater than a temperature threshold, the target energy storage mode is determined to be the second energy storage mode. Even if the ambient temperature is below the ambient temperature threshold, the target energy storage mode is determined to be the second energy storage mode. For example, in summer, even if the current temperature is low, it generally lasts for a short time, and the actual demand is still for cooling energy.

[0165] In this embodiment, determining the target energy storage mode in combination with season and weather information as well as ambient temperature will be more in line with actual needs.

[0166] Next, the process of determining the target energy storage mode in method 3 when the state perception information includes the vehicle's position, ambient temperature, and ambient light will be described.

[0167] refer to Figure 9 The process may include but is not limited to the following S901 to S903.

[0168] S901. The vehicle determines the weather information and season of the vehicle's location based on the location.

[0169] The implementation of S901 may refer to the detailed description of the weather information and season of the vehicle's location determined based on the vehicle's location in S701, which will not be repeated here.

[0170] S902: The vehicle determines an initial energy storage mode based on season and weather information.

[0171] The implementation of S902 may refer to the detailed description of the vehicle determining the target energy storage mode based on season and weather information in S702, which will not be described in detail here.

[0172] The difference is that here the target energy storage mode determined in S702 is used only as the initial energy storage mode.

[0173] S903: The vehicle adjusts the initial energy storage mode based on the ambient temperature and ambient light to determine the target energy storage mode.

[0174] The effect of ambient light on the required energy, i.e., the target energy storage mode, is similar to the effect of ambient temperature on the required energy, i.e., the target energy storage mode. For specific implementation, please refer to the description in S803 where the vehicle adjusts the initial energy storage mode based on the ambient temperature to determine the target energy storage mode. Details will not be repeated here.

[0175] In this embodiment, determining the target energy storage mode in combination with season and weather information, ambient light, and ambient temperature will be more in line with actual needs.

[0176] The energy control process of the vehicle is described below by taking an embodiment as an example.

[0177] With the rapid development of the automotive industry, the electrification and intelligent development of automobiles, and the continuous breakthroughs in technologies such as energy saving and endurance of new energy vehicles, new energy vehicles are also making more and more prominent use of new technologies in vehicle thermal management technology. For example, new energy vehicle heat pump air conditioning and new thermal management technology breakthroughs are being made. They are widely used in newly launched new energy vehicles. New energy vehicle thermal management control technology reduces energy consumption and improves endurance of new energy vehicles, manages battery charging and discharging and insulation / cooling thermal management, manages electric drive operation thermal management, and controls passenger compartment comfort thermal management. With the deepening of automobile electrification, the integrated control technology of new energy vehicle thermal management control is becoming more and more precise and intelligent based on traditional fuel. It fully utilizes the various thermal management modules of the vehicle to carry out central integrated management and control. In order to fully utilize the cold and hot energy sources of new energy vehicles, cold and hot energy is stored and heat exchange is carried out with high efficiency. Intelligent integrated central control of heat energy exchange is carried out. The goal is to use the cold and hot energy sources of the vehicle to improve the energy saving of new energy vehicles and improve the endurance of the vehicle, reduce the energy consumption of the thermal management system, and improve the daily user experience of the vehicle.

[0178] Currently, thermal management in most new energy vehicles is managed and controlled using a hierarchical system approach. Common management methods include battery TMS management, electric drive TMS management, passenger compartment TMS management, and traditional engine compartment TMS management. With the advancement of vehicle electrification, heat pump control technology and liquid charging thermal management technology have emerged. However, much of the thermal energy from the vehicle's heat-generating components is lost and underutilized. This embodiment, based on the reuse of thermal energy stored in new energy / hybrid vehicles, utilizes a centrally integrated control approach to fully utilize the vehicle's thermal energy. Furthermore, the storage unit optimizes the operating temperature of each execution unit's electrical components, such as the motor, charger, battery, and high-voltage line speed. Excess heat generated by the vehicle's electrical components during operation is stored, as is excess cooling energy after the air conditioning system has cooled. The solution addresses vehicle supercharging thermal management, low-temperature battery insulation, low-temperature charging thermal management, low-temperature passenger compartment heating, or new vehicle floor heating applications. It provides a control technology solution for the management and application of new energy and hybrid powertrain cooling and heat.

[0179] The core content of this embodiment scheme is to add a cold and heat storage and exchange device to store excess heat energy from the charging circuit and charger during new energy supercharging and fast and slow charging, or excess heat energy from the hybrid engine. Secondly, it stores cold energy after refrigeration. It fully utilizes cold energy and the vehicle's heat source to dissipate heat and cool the passenger compartment. This cold and heat energy storage and exchange device solves the problems of low-temperature charging in winter, low-temperature battery insulation, and passenger compartment heating. The cold source storage solves the problem of high-temperature battery cooling in summer, rapid cooling during supercharging and fast charging, lightweight charging wiring harnesses, and passenger compartment cooling. It improves the thermal management efficiency of new energy vehicles, reduces the energy consumption of new energy vehicles / hybrid vehicles, and improves the heating and cooling efficiency of the passenger compartment.

[0180] To implement the thermal management control technical solution, this embodiment provides a cold and hot storage exchange device (equivalent to the above-mentioned energy storage tank), a thermal management electronic controller (equivalent to the above-mentioned energy controller), and a new energy vehicle thermal management component.

[0181] To achieve both hot and cold storage and exchange, the hot and cold storage exchange device is structured based on the principle of heat conduction. The hot and cold storage device primarily consists of a double-layer gap formed between the inner and outer walls, with a vacuum or gas filled gap between the two layers to reduce heat conduction and achieve hot and cold storage. The hot and cold storage device comprises a stainless steel inner liner (including an insulation layer), a vacuum layer, a stainless steel outer layer (or heat-resistant outer shell), a 4-way control valve system at both ends, and a TMS (Electronic Control Unit) (ECU) for hot and cold storage and exchange.

[0182] The hot and cold storage device determines whether to store heat or cold, based on the conditions for hot and cold reserve exchange according to the ambient temperature outside the vehicle; the TMSECU system unit receives the ambient temperature sensor outside the vehicle to determine the energy storage mode; the energy storage mode is divided into winter energy storage mode (equivalent to the first energy storage mode mentioned above) and non-winter energy storage mode (equivalent to the second energy storage mode mentioned above); the non-winter energy storage mode determines whether the outdoor temperature is greater than 5°C; the winter energy storage mode is determined based on a temperature less than 5°C (-30°C ~ 5°C); the winter energy storage mode is hereinafter referred to as energy storage mode 1; the non-winter energy storage mode is referred to as energy storage mode 2.

[0183] The cold / hot storage device stores the vehicle coolant (temperature range -40°C to 100°C) as the cold / hot source medium; the cold / hot storage device determines the coolant mode in the storage tank based on the outside temperature of the vehicle.

[0184] In energy storage mode 1, the coolant temperature in the energy storage tank is 80℃~100℃. The thermal energy of the energy storage coolant is mainly used for heating the passenger compartment in winter, keeping the battery pack warm in low-temperature environments, keeping the battery management system (BMS) warm in low-temperature environments, and keeping the EMS motor control unit warm.

[0185] Energy storage mode 2, the coolant temperature in the energy storage tank is -20℃~5℃; it is mainly used for exchanging the cooling of the passenger compartment (equivalent to the above-mentioned cabin), the heat dissipation of the charger, charging circuit and battery pack in high temperatures in summer, the heat dissipation of the motor during vehicle driving, and the second exchange is for the vehicle charging equipment, charging / discharging battery, and the vehicle electric drive system to exchange heat.

[0186] The main purpose of thermal management of hot and cold storage devices is to improve the recovery rate of heat sources in severe winter; to store excess heat; to improve the vehicle's operation in adverse weather; to improve the heating of the passenger compartment in winter and the insulation of the vehicle's three-electric system by storing heat and cold; to improve cooling efficiency by storing cold sources in non-winter, to solve the problem of vehicle charging and cooling in high-temperature environments, and the cooling rate in the passenger compartment; secondly, to accurately ensure the heat exchange efficiency of heat-generating appliances and the charging and discharging three-electric system during vehicle operation.

[0187] Added a new cold and hot reserve exchange heat management system (equivalent to the energy management system of the above vehicle), reference Figure 10 As shown in the content, the cold and hot reserve exchange thermal management system includes a sensor module 1001 (equivalent to the above-mentioned data acquisition sensor), a heat energy providing module 1002 (equivalent to the above-mentioned heat energy providing component), a cold energy providing module 1003 (equivalent to the above-mentioned cold energy providing component), a cold / hot storage unit 1004 (equivalent to the above-mentioned energy controller), a cold / hot storage container tank 1005 (equivalent to the above-mentioned energy storage tank), a heat energy receiving module 1006 (equivalent to the above-mentioned heat energy demand component), a cold energy receiving module 1007 (equivalent to the above-mentioned cold energy demand component) and a mode determination module 1008.

[0188] The sensor module 1001 includes an outside temperature sensor 10011 (equivalent to the above-mentioned temperature sensor), a global positioning system (GPS) 10012 (equivalent to the above-mentioned position sensor), and a light sensor 10013 .

[0189] The heat energy providing module 1002 may include: a super / fast charging component 10021, a power battery heat source 10022, an engine / range extender 10023, a motor working component heat source 10024, and an air conditioning system PTC / heat pump / condenser heat source 10025.

[0190] The cooling energy providing module 1003 may include: an air-conditioning system evaporator (cooling energy) 10031 and an air-conditioning system compressor (cooling energy) 10032 .

[0191] The mode determination module 1008 may include: winter energy storage mode 1 (10081) (equivalent to the above-mentioned first energy storage mode) and non-winter energy storage mode 2 (10082) (equivalent to the above-mentioned second energy storage mode).

[0192] The heat receiving module 1006 may include: a passenger compartment heating / seat heating component 10061, a low-temperature environment battery insulation, an electric drive component 10062, and a low-temperature environment battery insulation, a battery control BMS / EMS electronic control unit insulation component 10063.

[0193] The cold energy receiving module 1007 may include: fast charging high-voltage wiring harness / battery / charging BMS heat exchange component 10071, electric drive working heat dissipation exchange / IPU controller heat exchange component 10072, spring and autumn air conditioning defogger exchange component 10073, passenger compartment rapid cooling exchange 10074, battery discharge / electric drive working cooling exchange component 10075.

[0194] The TMS control ECU of the thermal management control system on the new energy vehicle has added new hot and cold storage and hot and cold exchange control logic, and the judgment is based on the on-board external temperature sensor, GPS positioning / vehicle network signal, and the front windshield area photosensor on the vehicle side; the external temperature sensor collects the external temperature of the vehicle when it is stationary / driving, the GPS positioning / vehicle network signal locks the vehicle's geographical position, and the vehicle's front windshield photosensor monitors the light intensity; the TMS hot and cold storage ECU unit determines the energy storage mode based on the external temperature sensor and the vehicle-side positioning system. First, the onboard positioning system accurately determines the vehicle's location. Based on the vehicle's location and combined with onboard network signals, the system identifies the season of the region in which the vehicle is located. Based on the vehicle's weather forecast, it outputs a 15-day weather range signal to the TMS control ECU (Signal 1). The heating and cooling ECU initially determines the energy storage mode based on the region's season and the forecasted weather. The outside temperature sensor (Signal 2) monitors the outside temperature in real time and inputs this into the heating and cooling ECU to determine the revised conditions for heating and cooling reserves. The heating and cooling storage ECU then initially determines the region's season based on Signal 1 and then ultimately determines the energy storage mode based on the outside temperature. A light sensor collects the vehicle's external light intensity as an auxiliary signal, which is input into the heating and cooling ECU. This signal primarily serves as an auxiliary signal source for the TMS's heating / cooling cabin. After determining the energy storage mode, the heating and cooling storage ECU outputs a signal to the actuators of the heating and cooling storage tanks.

[0195] When the TMS hot and cold storage ECU unit instructs to output energy storage mode 1, the cold / hot storage container tank execution unit will monitor the coolant temperature above 80°C in combination with the temperature sensors in the operation of various systems of the vehicle, and the heat energy of the coolant circulation system will be stored in the hot and cold storage container tanks first; the main heat source is the coolant after the DC charging BMS high-voltage wiring harness and power battery are charged and heated when the vehicle is in fast charging / liquid supercharging; the high-temperature coolant is stored for hybrid engine starting (range extender starting), the high-temperature coolant of high-load motor components, and the high-temperature coolant of water-cooled PTC / heat pump / condenser.

[0196] In Energy Storage Mode 1, the storage tanks primarily store excess heat energy during vehicle operation. The hot and cold storage tanks offer excellent insulation performance, maintaining heat for 24 to 48 hours. Once hot coolant is stored in the hot and cold storage tanks, when the vehicle is in operation, the battery management system (BMS) of the power battery (power battery), the electric drive IPU (electric drive control unit) and the passenger compartment activate air conditioning and heating / seat heating. The storage tank actuators activate, allowing the stored high-temperature coolant to flow into the water inlets of the power battery / electric drive control unit (EVCU) and the passenger compartment water-cooled PTC module. This allows excess heat energy to be stored before heat exchange.

[0197] When the TMS hot and cold storage ECU unit instructs to output energy storage mode 2, the cold / hot storage container tank execution unit monitors the coolant temperature below 0°C in combination with the temperature sensors in the operation of various systems of the vehicle. The coolant in the coolant circulation system with lower temperature is preferentially stored in the hot and cold storage container tanks; new coolant cooling pipes are added to the air-conditioning system evaporator and the air-conditioning compressor refrigeration pipe coolant pipe; when the vehicle enters fast charging and the passenger compartment air-conditioning cooling operation, the cold / hot storage unit will output a cooling reserve signal to cool the coolant and store it in the container tank during the operation of the air-conditioning system; in energy storage mode 2, the energy storage container tank stores coolant below 5°C; the stored low-temperature coolant will be used for cooling exchange of the vehicle's high-voltage wiring harness / power battery / charging BMS, heat dissipation exchange of the IPU control unit and electric drive, discharge and cooling exchange of the power battery, hot and cold exchange of air-conditioning defrosting and demisting in spring and autumn, and ventilation and cooling exchange of the passenger compartment.

[0198] The structure of cold / hot storage container tank can refer to Figure 11 The structure shown includes a stainless steel liner (including insulation) 1101 (equivalent to the aforementioned inner insulation layer), a vacuum and thermal insulation layer 1102 (equivalent to the aforementioned gap), a stainless steel outer layer (or heat-resistant outer shell) 1103 (equivalent to the aforementioned heat-resistant outer shell), and a four-way solenoid valve body 1104. This structure is adjustable in size depending on the vehicle's installation location, and the insulation principle is based on that of a daily thermos cup. The internal materials are a stainless steel liner (including insulation), a high-vacuum and thermal insulation middle layer, a stainless steel outer layer or heat-resistant outer shell, four-way solenoid valve bodies and water pipe assemblies added to the left and right ends, and the storage tank stores coolant.

[0199] For example, the new cold and hot energy storage and utilization thermal management structure of the cold and hot energy storage container can refer to Figure 12 The contents shown include: air conditioning box 1201, new energy three-electric module 1202, heating heat exchanger 1203, water pump 1204, PTC heater 1205, engine / range extender 1206, expansion valve 1207, four-way valve 1208, compressor 1209, gas-liquid separator 1210, outdoor heat exchanger 1211, and hot and cold storage container tank 1212.

[0200] The air conditioning box 1201 may include a warm air core 12011 and an indoor cooling system 12012 .

[0201] The new energy three-electric module 1202 can include: IPU electric drive 12021, power battery 12022, and charging BMS control unit / fast charging and heat dissipation integrated module 12023.

[0202] When the TMS hot and cold storage ECU unit issues a command to the hot and cold energy storage tank actuator (four-way solenoid valve body); the hot and cold storage tank containers can be arranged according to different vehicle models, and the storage tank volume can be designed in the range of 5 to 10 liters (L); when the hot and cold storage ECU unit executes energy storage mode 1 (winter energy storage mode).

[0203] The temperature sensor of the TMS control unit collects the water temperature of the engine / range extender coolant. If the engine / range extender is in working condition and the water temperature reaches above 80℃, the radiator will execute the cooling instruction. When the cooling water temperature in the cold and hot storage is lower than 80℃, the four-way valve of the cold and hot storage container tank will open the two-section four-way solenoid valve body to use the internal low water temperature for the engine / range extender circulation cooling; the high-temperature engine water temperature of the engine / range extender will flow into the container tank through the solenoid valve body section of the cold and hot storage container tank; when the average water temperature in the cold and hot storage tank is greater than 80℃; the solenoid valve body switch is closed, and the state enters the high-temperature coolant winter heat storage mode.

[0204] When the air conditioner PTC / heat pump air conditioner enters heating mode and the coolant water temperature is greater than 80℃; and the temperature in the passenger compartment has entered a steady state; the excess heat energy storage conditions are met; the TMS thermal energy storage ECU unit will issue an energy storage command, and the air conditioner box heating four-way valve will open the hot and cold energy storage pipelines, diverting the high-temperature coolant into the storage container tank unit; the non-high-temperature coolant in the storage container tank will enter the TMS low-temperature circulation pipeline or be used for temperature balance of the electric drive and power battery, and BMS control unit; in this way, the excess heat energy in the TMS heating process is stored.

[0205] When the vehicle's high-heat heat source is not working, such as the engine / range extender, PTC / heat pump air conditioner is not working; when the vehicle's overall cooling water temperature is low in a low-temperature environment; the TMS energy storage ECU unit will make a comparison and judgment based on the temperature of each heat-generating coolant; when the outdoor temperature reaches above 30°C and the coolant in the hot and cold storage containers is lower than the coolant temperature of the heat-generating unit, the four-way solenoid valve will open to store energy for thermal energy storage.

[0206] When a vehicle is supercharging / fast charging in winter conditions, the vehicle's TMS monitors the temperature rise within the BMS charger, the high-voltage charging wiring harness, and the power battery pack. After the high-voltage charger, the high-voltage wiring harness, and the power battery pack have reached steady state, the TMS energy storage ECU compares the temperature difference between the energy storage tank and the BMS charger, the high-voltage charging wiring harness, and the power battery pack as the temperature continues to rise. When the temperature inside the energy storage tank is 20°C lower than the temperature of the heating element during charging, the energy storage ECU solenoid valve activates the energy storage heat exchange. Thermal management controls the utilization of hot and cold energy in the hot and cold energy storage containers as follows: In winter, the vehicle's engine / range extender and heating system are essentially operational, and the coolant temperature (excess heat) can reach above 80°C.

[0207] The high heat stored in the energy storage tank is primarily used to insulate the power battery pack at night and control battery temperature during driving. During low-temperature PTC heating, the TMS energy storage ECU swaps high-heat coolant with the PTC heating line. In winter, high-heat coolant is swapped for low-temperature coolant within the integrated BMS control unit, allowing the unit to quickly reach operating temperature using the stored heat. This new thermal management system for hot and cold energy storage fully utilizes the vehicle's excess heat, reducing energy consumption and accelerating temperature ramp-up times during the initial startup and heating phases in low-temperature environments.

[0208] The non-winter energy storage mode (energy storage mode 2) mainly stores the coolant that is colder after the vehicle coolant is cooled by the air-conditioning compressor or evaporator. According to the structural diagram, the stored coolant is used for vehicle charging BMS / power battery pack and electric drive cooling exchange, and initial air outlet cooling exchange in the passenger compartment.

[0209] This embodiment has the following technical effects: Compared to related technologies, this thermal management control technology adds TMS hot and cold energy storage control and a TMS hot and cold energy storage tank. This thermal management control technology primarily collects excess high-temperature coolant from the hybrid engine and PTC module heating process in winter, insulates and stores it, and then uses it to interact with the power battery, BMS control unit, and initial air conditioning heating to provide high-temperature coolant in low-temperature environments, improving heating efficiency. During non-winter conditions, this thermal management control technology primarily stores excess cold energy from the air conditioner, cooling the coolant to a lower temperature for cold insulation storage. This lower temperature coolant is then used to cool the coolant during supercharging and rapid charging, and to cool the passenger compartment during initial high temperatures.
