Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to a vehicle battery heating control method, system, vehicle and storage medium. Background Art

[0002] Battery heating control technology is a key element in ensuring stable and efficient battery operation under various operating conditions. It directly impacts battery performance, vehicle economy, and driving safety. However, existing technologies in this area, particularly for the complex operating conditions of commercial vehicles, have limitations.

[0003] Existing battery heating control strategies primarily include fixed-threshold control strategies and driving state-adjusted control strategies. The fixed-threshold control strategy sets a fixed heating trigger point, activating the heating system once the battery temperature falls below the set threshold. However, it ignores key factors such as the driving state of commercial vehicles, resulting in energy waste and impacting the vehicle's economy and driving mode. When applied to commercial vehicle scenarios, the adaptability and accuracy of the driving state-adjusted control strategy need to be improved. Therefore, effectively improving the accuracy of commercial vehicle battery heating control is a key technical issue in this area.

[0031] Figure 1 FIG. 1 is a flow chart of a vehicle battery heating control method according to one embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0032] Step S101: Acquire vehicle power type and vehicle data within a preset time period.

[0033] Optionally, the vehicle power type is obtained, that is, whether the vehicle is a pure electric vehicle or a hybrid vehicle. Different types of power systems have different requirements and response mechanisms for battery heating.

[0034] Optionally, the vehicle data acquired during a preset time period includes parameters such as vehicle speed, slope, accelerator pedal opening, brake pedal opening, battery state of charge (SOC), battery cell temperature, and ambient temperature. This data provides an overview of the vehicle's operating conditions during the preset time period, providing key information for intelligently assessing battery heating needs.

[0035] Step S102 : determining the battery heating type according to the vehicle power type and vehicle data.

[0036] Intelligently determine the battery heating type based on the vehicle's power type and vehicle data. The battery heating type is determined based on the vehicle's power type and in-depth analysis of vehicle data to more accurately match actual needs and reduce energy waste.

[0037] Step S103 : determining a battery heating control strategy according to the battery heating type and the battery thermal environment difference data, wherein the battery thermal environment difference data is used to describe the temperature difference between the battery cell and the environment at the current moment.

[0038] After determining the battery heating type, the specific battery heating control strategy is determined by further combining the battery thermal environment difference data.

[0039] It should be noted that battery thermal environment difference data is used to quantify the temperature difference between the battery cell and the external environment. This data reflects the thermal conditions of the battery and helps to accurately determine the battery heating control strategy.

[0040] Step S104 : performing heating control on the vehicle battery according to the battery heating control strategy.

[0041] According to the determined battery heating control strategy, specific heating operations are performed and the output of the heating system is adjusted to meet the temperature requirements of the battery under the current operating conditions.

[0042] In an embodiment of the present invention, the vehicle power type and vehicle data within a preset time period are obtained; the battery heating type is determined based on the vehicle power type and vehicle data; the battery heating control strategy is determined based on the battery heating type and battery thermal environment difference data, wherein the battery thermal environment difference data is used to describe the temperature difference between the battery cell and the environment at the current moment; and the vehicle battery is heated according to the battery heating control strategy. The present invention determines the battery heating type based on the vehicle power type and vehicle data. This dynamic determination of the battery heating type ensures that the subsequent heating operation matches the vehicle operating conditions, thereby effectively enhancing the accuracy of commercial vehicle battery heating control. Based on the determination of the battery heating type, the battery thermal environment difference data is further combined to determine a suitable heating control strategy. The introduction of the battery thermal environment difference data enables the control strategy to cope with the challenges brought about by changes in battery temperature and ambient temperature, further improving the accuracy of commercial vehicle battery heating control, thereby solving the technical problem of how to effectively improve the accuracy of commercial vehicle battery heating control.

[0043] Optionally, the vehicle power type includes a hybrid power type, and determining the battery heating type according to the vehicle power type and vehicle data includes the following steps:

[0044] Step S1021, in response to the vehicle power type being a hybrid type, determining the vehicle driving scene and the vehicle gross weight based on the vehicle data;

[0045] In an optional embodiment, the vehicle power type is a hybrid type, and the vehicle driving scenario and the vehicle gross weight are further determined based on the vehicle data.

[0046] In an optional embodiment, a hybrid vehicle is a vehicle that uses both an internal combustion engine and an electric motor as its power sources. This power configuration allows the vehicle to flexibly switch between or use both power sources simultaneously based on driving needs, increasing energy flexibility and efficiency.

[0047] The identification of vehicle driving scenarios is the basis for dynamically adjusting the battery heating control strategy. In different scenarios, the battery heating requirements and economic considerations are different.

[0048] It should be noted that the gross weight of the vehicle has a direct impact on the battery heating demand. The greater the gross weight, the higher the vehicle's demand for battery power.

[0049] Step S1022: Determine the battery heating type based on the vehicle driving scenario and the gross vehicle weight.

[0050] Comprehensively analyze the vehicle's specific driving scenarios and load conditions, and dynamically select the battery heating type that matches the current vehicle's actual needs from a variety of preset battery heating types.

[0051] Optionally, the vehicle power type further includes a pure electric power type. Determining the battery heating type according to the vehicle power type and vehicle data includes the following steps:

[0052] Step S1023, in response to the vehicle power type being a pure electric power type, determining the vehicle driving scene, the vehicle gross weight, and the current battery state of charge data based on the vehicle data;

[0053] In an optional embodiment, the vehicle power type is a pure electric power type, and the vehicle driving scene, vehicle gross weight and current battery state of charge data are further determined based on the vehicle data.

[0054] Pure electric vehicles rely entirely on electric motors and battery systems as their power source, without an internal combustion engine. In the embodiments of this application, due to the single energy source, the battery heating control strategy for pure electric vehicles requires a more refined design to ensure efficient energy utilization and stable battery performance in different driving scenarios and gross weight conditions.

[0055] The gross vehicle weight, which includes the vehicle's own weight and the weight of the loaded cargo, is an important factor affecting the vehicle's energy consumption and battery heating requirements.

[0056] The battery's state of charge (SOC) data reflects the ratio of the battery's current stored charge to its maximum stored charge, a value between 0 and 1. SOC data is particularly important for pure electric vehicles, as the battery is the vehicle's sole energy storage and supply unit. Its SOC level directly affects the vehicle's range and heating strategy.

[0057] Step S1024 : determining the battery heating type based on the vehicle driving scene, the vehicle gross weight, and the current battery state of charge data.

[0058] Based on the determined vehicle driving scenario, the vehicle's gross weight, and the current battery state of charge data, a battery heating type that matches the actual needs of the current vehicle is determined from a plurality of preset battery heating types.

[0059] It is not difficult to understand that based on the vehicle driving scenario, gross vehicle weight and current battery state of charge data, the battery heating needs can be accurately assessed, thereby effectively selecting the appropriate battery heating type.

[0060] Optionally, the vehicle driving scenario includes a congestion scenario, a normal driving scenario, a mountain uphill scenario, a mountain downhill scenario, an urban scenario, a suburban scenario, and a highway scenario; the battery heating type includes a first heating type, a second heating type, a third heating type, a fourth heating type, and a fifth heating type; and determining the battery heating type according to the vehicle driving scenario and the gross vehicle weight includes the following steps:

[0061] Step S10221, determining the vehicle load state according to the gross vehicle weight, wherein the vehicle load state includes an empty state, a standard load state, and an overload state;

[0062] The vehicle's load status is determined by the gross vehicle weight. In an optional embodiment, the vehicle's load status is categorized as unloaded, standard loaded, and overloaded. Unloaded refers to a vehicle without cargo or passengers, standard loaded indicates a load that meets standards or expectations, and overloaded refers to a vehicle with cargo exceeding the designed or specified weight. The vehicle's load status has a direct impact on the type of battery heating, as different load statuses result in different thermal requirements and energy consumption for the battery under the same operating conditions.

[0063] It should be noted that the load ranges corresponding to different vehicle load states are pre-set.

[0064] Step S10222: in response to the vehicle load state being an empty state and the vehicle driving scene being any one of a congestion scene and an urban scene, determining that the battery heating type is a first heating type;

[0065] In an optional embodiment, a heating type query table is pre-set, which specifies the battery heating types corresponding to different vehicle driving scenarios and different vehicle load conditions.

[0066] For example, Table 1 is a heating type lookup table corresponding to a hybrid vehicle.

[0067] Table 1

[0068] No load Standard load overload Congestion scenario Category 1 Category 1 Category 2 City Scene Category 1 Category 2 Category 2 Suburban (or national highway) scenes Category 2 Category 2 Category 3 Normal driving scenario Category 2 Category 2 Category 3 High-speed scene Category 2 Category 3 Category 4 Mountain downhill scene Category 3 Category 4 Category 5 Mountain uphill scene Category 4 Category 5 Category 5

[0072] It should be noted that the normal driving scenario is used to characterize the vehicle driving condition as a standard driving condition.

[0081] In an optional embodiment, based on the provisions in Table 1, when the vehicle load state is the standard load state and the vehicle driving scene is a normal driving scene, an urban scene or a suburban scene, the battery heating type is determined to be category 2, that is, the second heating type.

[0082] Step S10228, in response to the vehicle load state being the standard load state and the vehicle driving scene being the high-speed scene, determining that the battery heating type is the third heating type;

[0083] In an optional embodiment, based on the provisions in Table 1, when the vehicle load state is the standard load state and the vehicle driving scene is a high-speed scene, the battery heating type is determined to be category 3, that is, the third heating type.

[0084] Step S10229, in response to the vehicle load state being the standard load state and the vehicle driving scene being a downhill mountain scene, determining that the battery heating type is the fourth heating type;

[0086] Step S102210 , in response to the vehicle load state being the standard load state and the vehicle driving scene being an uphill scene in a mountainous area, determining that the battery heating type is the fifth heating type.

[0087] Similarly, based on the provisions in Table 1, when the vehicle load state is the standard load state and the vehicle driving scene is an uphill scene in a mountainous area, the battery heating type is determined to be category 5, that is, the fifth heating type.

[0088] Optionally, determining the battery heating type based on the vehicle driving scenario and the gross vehicle weight further includes the following steps:

[0089] Step S102211: in response to the vehicle load state being an overloaded state and the vehicle driving scene being any one of a congestion scene and an urban scene, determining that the battery heating type is a second heating type;

[0090] Similarly, in an optional embodiment, based on the provisions in Table 1, when the vehicle load state is overloaded and the vehicle driving scene is a congested scene or an urban scene, the battery heating type is determined to be category 2, that is, the second heating type.

[0091] Step S102212: in response to the vehicle load state being an overloaded state and the vehicle driving scene being any one of a normal driving scene and a suburban scene, determining that the battery heating type is a third heating type;

[0092] Similarly, based on the provisions in Table 1, when the vehicle load state is overloaded and the vehicle driving scene is a normal driving scene or a suburban scene, the battery heating type is determined to be category 3, that is, the third heating type.

[0094] Similarly, based on the provisions in Table 1, when the vehicle load state is overloaded and the vehicle driving scene is a high-speed scene, the battery heating type is determined to be category 4, that is, the fourth heating type.

[0095] Step S102214: In response to the vehicle load state being an overload state and the vehicle driving scene being any one of a mountain downhill scene and a mountain uphill scene, determining that the battery heating type is the fifth heating type.

[0096] Similarly, based on the provisions in Table 1, when the vehicle load state is overloaded and the vehicle driving scene is a downhill scene in a mountainous area or an uphill scene in a mountainous area, the battery heating type is determined to be category 5, that is, the fifth heating type.

[0097] It should be noted that different heating types reflect different vehicle heating requirements. Each type corresponds to specific parameters such as heating intensity, mode, and duration. The battery heating type is selected based on an assessment of the vehicle's current operating status to adapt to the battery thermal management requirements under different operating conditions.

[0098] It's easy to understand that by combining the vehicle's driving scenario with its load status, the present embodiment dynamically determines the battery heating type to suit the vehicle's actual needs under different operating conditions. Compared to traditional fixed strategies, this approach significantly reduces energy waste and improves energy efficiency, while ensuring that the battery remains within its optimal operating temperature range under all driving conditions. This extends battery life, improves battery performance, and enhances the economy and reliability of new energy vehicles.

[0099] Optionally, determining the battery heating type according to the vehicle driving scenario, the vehicle gross weight, and the current battery state of charge data includes the following steps:

[0100] Step S10241, determining the vehicle load status according to the gross vehicle weight;

[0101] Analyze the gross vehicle weight and determine the vehicle's load status, that is, whether the vehicle is currently unloaded, loaded to standard, or overloaded.

[0103] Based on the current battery state of charge data, the vehicle's charge state is determined, i.e., low, normal, or fully charged. Determining the charge state is another key factor in determining the battery heating strategy. Depending on the charge state, the battery temperature control strategy needs to be adjusted accordingly to avoid energy waste.

[0104] It should be noted that the battery state of charge data intervals corresponding to different power states are pre-set.

[0105] Step S10243: determining a battery heating type query table according to the vehicle power state, wherein the battery heating type query table includes a low-power battery heating type query table, a normal-power battery heating type query table, and a fully-charged battery heating type query table;

[0106] Based on the vehicle's power status, the corresponding battery heating type query table is selected. For example, if the vehicle is in a low-power state, the low-power battery heating type query table will be used to ensure that the battery heating strategy can still meet the vehicle's operating needs when the power is limited, while maximizing energy conservation.

[0107] For example, Table 2 is a query table of low-battery heating types corresponding to pure electric vehicles.

[0110] For example, Table 3 is a normal battery heating type lookup table corresponding to a pure electric vehicle.

[0112] No load Standard load overload Congestion scenario Category 1 Category 1 Category 1 City Scene Category 1 Category 1 Category 2 Suburban (or national highway) scenes Category 1 Category 2 Category 2 Normal driving scene Category 2 Category 2 Category 2 High-speed scene Category 2 Category 2 Category 3 Mountain downhill scene Category 2 Category 3 Category 3 Mountain uphill scene Category 3 Category 3 Category 4

[0113] For example, Table 4 is a lookup table of fully charged battery heating types corresponding to pure electric vehicles.

[0114] Table 4

[0115] No load Standard load overload Congestion scenario Category 1 Category 1 Category 2 City Scene Category 1 Category 2 Category 2 Suburban (or national highway) scenes Category 2 Category 2 Category 3 Normal driving scene Category 2 Category 2 Category 3 High-speed scene Category 2 Category 3 Category 4 Mountain downhill scene Category 3 Category 4 Category 5 Mountain uphill scene Category 4 Category 5 Category 5

[0116] Step S10244: Determine the battery heating type based on the vehicle driving scenario, vehicle load status, and a battery heating type query table.

[0117] The optimal battery heating type is determined by combining the vehicle's driving scenario, load status, and the selected battery heating type lookup table. This comprehensive process considers multiple factors and effectively addresses the challenges of battery temperature management in complex vehicle operating conditions.

[0118] Optionally, determining a battery heating control strategy based on the battery heating type and the battery thermal environment difference data includes the following steps:

[0119] Step S1031, determining the battery target heating temperature according to the battery heating type;

[0120] Based on the determined battery heating type, the target battery heating temperature is determined. The determination of the target heating temperature must take into account the characteristics of the battery heating type and the vehicle's operating conditions to ensure the battery operates at an appropriate temperature while also taking into account energy efficiency.

[0121] In an optional embodiment, the vehicle driving scenario, gross vehicle weight, and SOC determine the target battery heating temperature.

[0122] In an optional embodiment, a target heating temperature lookup table is pre-set, which specifies the battery target heating temperatures corresponding to different battery heating types. After the battery heating type is determined, the target heating temperature can be determined by querying the target heating temperature lookup table.

[0123] Step S1032, determining target battery water inlet parameters according to the battery heating type and the battery thermal environment difference data, wherein the target battery water inlet parameters include a target battery water inlet temperature and a target battery water flow rate;

[0124] Furthermore, according to the battery heating type and the battery thermal environment difference data, the battery target water inlet parameters, namely the battery target water inlet temperature and target water flow rate, are determined.

[0125] In an optional embodiment, the vehicle driving scenario, the vehicle's gross weight, the SOC, and the temperature difference between the battery cell and the environment jointly determine the heating rate (ie, the battery's target water inlet temperature and the battery's target water flow rate).

[0126] Determine the target water inflow parameters for the battery to ensure that the battery heating rate can quickly raise the battery temperature to the target heating temperature while avoiding overheating when the battery thermal environment difference is small, thereby saving energy.

[0127] Step S1033 : determining a battery heating control strategy based on the battery target heating temperature and the battery target water inflow parameter.

[0128] The specific battery heating control strategy is determined based on the target battery heating temperature and target battery water inflow parameters. This strategy will guide the actual operation of the battery heating system, including the selection of heating mode, setting of heating intensity, and duration of the heating process, ensuring the comprehensiveness and accuracy of the battery heating process.

[0129] In an optional embodiment, the battery heating strategy refers to formulating strategy parameters such as the battery target heating temperature, the battery target water inlet temperature, and the battery target water flow rate based on the battery temperature-rate table, the battery SOC-rate table, the battery overheat threshold, and the battery safety threshold.

[0130] Optionally, determining a target water inflow parameter for the battery based on the battery heating type and battery thermal environment difference data includes the following steps:

[0131] Step S10321: determining the battery's initial water inlet parameters according to the battery heating type, wherein the battery's initial water inlet parameters include the battery's initial water inlet temperature and the battery's initial water flow rate;

[0132] According to the determined battery heating type, the battery initial water inlet parameters, namely the battery initial water inlet temperature and the battery initial water flow rate, are set to provide a basic reference for the subsequent heating process.

[0133] Optionally, a battery initial water inflow parameter query table is pre-set, which specifies the initial water inflow parameter values corresponding to different battery heating types. After determining the battery heating type, the battery initial water inflow parameter can be determined by querying the battery initial water inflow parameter query table.

[0134] Step S10322: determining a temperature difference type based on the battery thermal environment difference data, wherein the temperature difference type includes a high temperature difference type and a low temperature difference type;

[0135] Based on the size of the battery thermal environment difference data, the battery temperature difference type is determined to be high or low. A high temperature difference type means that the battery needs to be heated quickly to reach the target temperature, while a low temperature difference type indicates that the battery temperature is close to the ambient temperature, and the heating process can be more gentle.

[0136] Step S10323: determining a target increment according to the temperature difference type, wherein the target increment includes a target inlet water temperature increment and a target water flow increment;

[0137] In an optional embodiment, when the temperature difference type is a high temperature difference type, the target water inlet temperature increment is a preset temperature increment value, and the target water flow increment is a preset water flow increment value. When the temperature difference type is a low temperature difference type, the target water inlet temperature increment is 0, and the target water flow increment is 0.

[0138] The target increment is used to adjust the initial water inflow parameter values for the battery. Setting the target increment ensures that the heating process meets the required battery temperature increase while also allowing for flexible adjustment of the heating rate based on the temperature difference between the battery and the surrounding environment.

[0139] Step S10324, determining the target battery inlet water temperature based on the target inlet water temperature increment and the initial battery inlet water temperature;

[0140] Optionally, the target water inlet temperature increment and the initial battery water inlet temperature are summed to determine the target battery water inlet temperature. This process ensures that the water temperature can be accurately raised to the required level during the heating process to meet the battery heating requirements.

[0141] Step S10325, determining the battery target water flow rate based on the target water flow rate increment and the battery initial water flow rate;

[0142] Similarly, the target water flow rate increment and the initial water flow rate of the battery are summed to determine the target water flow rate of the battery.

[0143] The setting of the battery target water flow rate ensures that the water flow rate during the heating process can meet the battery heating efficiency requirements, while avoiding the energy waste that may be caused by overheating.

[0144] Step S10326: Determine the battery target water inlet parameters according to the battery target water inlet temperature and the battery target water flow rate.

[0145] The battery target water inlet parameters determined according to the battery target water inlet temperature and the battery target water flow rate are used to guide the actual operation of the battery heating system.

[0146] For example, Table 5 is a lookup table of target parameter values corresponding to pre-set battery heating types. Based on the determined battery heating type, target water inlet temperature increment (ΔT), and target water flow increment (ΔL), combined with Table 5, the target battery heating temperature, target water inlet temperature, and target water flow can be determined.

[0147] Optionally, when the temperature difference between the battery cell and the environment is a high temperature difference type, ΔT and ΔL take preset values; when the temperature difference between the battery cell and the environment is a low temperature difference type, ΔT and ΔL are both 0.
