Description

Technical Field

[0001] The present invention relates to the technical field of thermal management control, and in particular to a thermal management control method, system, medium, equipment and vehicle for vehicle precooling. Background Art

[0002] With the gradual increase in the number of electric vehicles, super-fast charging has also become the focus of industry attention. The maximum charging current of super-fast charging is mainly affected by the battery power and battery temperature. When the battery power has not reached the reduction rate power, the charging speed can be increased as much as possible while ensuring the battery warranty life. When the reduction rate power is reached, a step-by-step reduction rate charging will occur; at the same time, if the battery temperature is higher than the limit temperature, even if the power has not reached the reduction rate power, the charging rate will still be greatly reduced; and the heat generated during the charging process during super-fast charging is much greater than that under driving conditions. If the thermal control strategy of normal driving conditions is followed, cooling is requested only when approaching the limit temperature critical value, and the charging current will be reduced in steps in advance. It can be seen that super-fast charging has higher requirements on battery temperature than normal driving, and the battery thermal management strategy for controlling super-fast charging is particularly important.

[0003] In addition, when the user chooses to charge immediately when the battery is low after driving for a long time, if the battery temperature is high at this time, the super fast charging will not be able to cover the SOC range of 0-80%, affecting the user's charging experience. Therefore, there is an urgent need for a reasonable thermal management control strategy to ensure that the user can charge immediately after driving and can also charge at the maximum rate to the reduced rate. Summary of the Invention

[0004] In order to overcome the defects and shortcomings of the prior art, the present invention provides a thermal management control method for vehicle pre-cooling. The present invention activates the pre-cooling function of the vehicle's on-board power battery according to the battery power and the battery power threshold of the pre-cooling function. After the pre-cooling function is activated, the corresponding pre-cooling temperature threshold is determined according to each SOC interval. The pre-cooling of the on-board power battery is started or ended according to the battery temperature and the pre-cooling temperature threshold corresponding to the SOC interval, and the on-board power battery is cooled, thereby ensuring that the battery temperature at the start of fast charging is within an ideal range, and ensuring that the user can charge immediately after driving and perform super-fast charging at the maximum rate to the reduced rate power.

[0020] As a preferred technical solution, the driving modes include power-saving driving mode, economic driving mode, normal driving mode and sports driving mode. When the vehicle's driving mode is in normal driving mode or sports driving mode, and the battery power is lower than the battery power threshold of the pre-cooling function, the pre-cooling function of the vehicle's on-board power battery is activated.

[0021] As an optimal technical solution, the preset battery power threshold of the pre-cooling function also includes a preset hysteresis value. When it is detected that the battery power is lower than the sum of the battery power threshold of the pre-cooling function and the hysteresis value, the pre-cooling function of the vehicle's on-board power battery is activated.

[0022] As a preferred technical solution, the pre-cooling temperature threshold includes a pre-cooling start threshold and a pre-cooling exit threshold, and the pre-cooling start threshold of the current SOC interval is equal to the pre-cooling exit threshold of the next adjacent SOC interval.

[0036] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0037] (1) The present invention activates the pre-cooling function of the vehicle's on-board power battery according to the battery power and the battery power threshold of the pre-cooling function. After the pre-cooling function is activated, the corresponding pre-cooling temperature threshold is determined according to each SOC interval, and the pre-cooling of the on-board power battery is controlled to start or end according to the battery temperature and the pre-cooling temperature threshold corresponding to the SOC interval, thereby cooling the on-board power battery, thereby ensuring that the battery temperature at the start of fast charging is within an ideal range, ensuring that the user can perform super-fast charging at the maximum rate to the reduced rate power immediately after driving, thereby improving the efficiency of thermal management control and charging efficiency.

[0038] (2) The present invention also activates the vehicle's onboard power battery pre-cooling function in combination with the vehicle's driving mode, thereby improving the efficiency and applicability of the thermal management control of the vehicle's pre-cooling.

[0039] (3) The present invention also adds a hysteresis value when presetting the battery power threshold of the pre-cooling function. When the battery power is detected to be lower than the sum of the battery power threshold of the pre-cooling function and the hysteresis value, the pre-cooling function of the vehicle's on-board power battery is activated. The addition of the hysteresis value can avoid the thermal management judgment jump caused by braking recharging, thereby improving the accuracy of thermal management control.

[0043] Figure 2 Schematic diagram of the process flow of the thermal management control method for vehicle pre-cooling including a driving mode detection step according to the present invention. DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] Example 1

[0046] like Figure 1 As shown, this embodiment provides a thermal management control method for vehicle precooling, including the following steps:

[0047] S1: Detect the vehicle status and the battery level when the vehicle is powered on;

[0048] S2: preset battery charge threshold for pre-cooling function;

[0049] In this embodiment, the thermal management control of vehicle pre-cooling needs to consider the battery power during driving. On the one hand, the probability of users recharging is low when the battery power is high. On the other hand, when the battery power is high, super-fast charging has a small charging time and temperature rise, so there is no need to cool the battery pack in advance. At the same time, the battery power threshold Q2 for activating the super-fast charging pre-cooling function can be calculated based on the temperature rise rate dT and the maximum charging rate dQ at the maximum super-fast charging rate. Specifically, it includes:

[0050] Q2=Q1-dQ(T 限制 -T 行驶 ) / dT

[0051] Among them, Q2 represents the battery power threshold of the pre-cooling function, Q1 represents the battery's maximum rate charging limit value, that is, when the power reaches this value in the super fast charging state, the charging current needs to be reduced for safety and battery life; dQ represents the maximum charging rate of the battery, and the preferred range in this embodiment is 5% / min-10% / min; T 限制 T represents the temperature threshold during the process of charging to Q1 at the maximum rate. The preferred value in this embodiment is 45°C. 行驶 dT represents the temperature threshold under the vehicle's powered-on driving condition. The preferred value in this embodiment is 38°C. dT represents the temperature rise rate during maximum-rate charging, which is primarily affected by the ambient temperature. Therefore, dT is a one-dimensional lookup table for ambient temperatures. The specific value can be determined through extensive vehicle testing. For example, an ambient temperature of 20°C corresponds to a dT of 1.5°C / min, and an ambient temperature of 35°C corresponds to a dT of 2°C / min.

[0052] If the temperature effect is not considered, the maximum charging rate dQ of super fast charging will decrease step by step until the battery is fully charged and reaches 0 after the battery capacity is greater than Q1 (80%) to ensure battery life and safety. The goal of super fast charging cooling is to ensure that the fast charge is charged to Q1 at the maximum rate, that is, the temperature will not exceed T during the charging process to Q1. 限制 (45℃) and reduce the charge rate;

[0053] S3: When the battery power level is detected to be lower than the battery power threshold of the pre-cooling function, the pre-cooling function of the vehicle's onboard power battery is activated;

[0054] S4: Divide the battery power into multiple SOC intervals according to the set intervals, and determine the corresponding pre-cooling temperature threshold according to each SOC interval. SOC, which stands for state of charge, is used to reflect the remaining capacity of the battery. Its numerical value is defined as the ratio of the remaining capacity to the battery capacity, usually expressed as a percentage;

[0055] S5: Determine the SOC range based on the battery power, detect the maximum temperature of the vehicle power battery, and control the start or end of pre-cooling of the vehicle power battery based on the pre-cooling temperature threshold corresponding to the maximum battery temperature and the SOC range.

[0056] In this embodiment, when cooling is requested while driving, the air conditioning's cooling capacity is partially diverted to the cockpit, reducing the battery pack's cooling by 1°C in approximately 3 minutes. However, when the air conditioning is operating at full capacity, Super Fast Charging raises the battery temperature by 1°C in approximately 30 seconds. Therefore, if battery cooling is enabled when the battery is nearly depleted, the battery temperature will not be reduced to the ideal value. If cooling is enabled according to the high-power fast charging temperature threshold when the battery level is high, wasteful battery loss will occur. Furthermore, users may choose to charge at any level between 0 and Q2. Therefore, this embodiment divides the battery level into multiple SOC intervals based on set intervals, and determines the corresponding pre-cooling temperature threshold for each SOC interval. This utilizes a stepped cooling threshold system based on the battery level. The battery level is divided into several SOC intervals, and as the SOC intervals decrease, the cooling threshold steps also decrease, meaning that the cooling requirements increase with decreasing levels. This stepped temperature control system allows users to charge from any level between 0 and Q2, ensuring maximum charging rate up to Q1. This ensures that the temperature does not reach the drop-rate threshold even after charging to Q1, thereby improving charging efficiency.

[0057] like Figure 2 As shown, it also includes a driving mode detection step, detecting the driving mode of the vehicle, and activating the pre-cooling function of the vehicle's on-board power battery when the vehicle's driving mode is in the set driving mode and the battery power is lower than the battery power threshold of the pre-cooling function.

[0058] In this embodiment, part of the electricity is consumed during driving to cool the battery in order to achieve a better charging experience. Therefore, it is necessary to identify the user's current driving needs. The vehicle driving mode (different OEMs will have different names to distinguish different driving experiences, that is, allowing users to choose energy saving or sports performance) includes power-saving driving mode, economic driving mode, regular driving mode, sports driving mode, etc. Among them, the power-saving driving mode and economic driving mode focus on overall endurance and power consumption. At this time, consuming electricity for battery cooling will be inconsistent with the driver's wishes, while the regular driving mode and sports driving mode care more about the driving experience, that is, the pursuit of performance. Therefore, the super fast charging pre-cooling function can be activated in this mode. The specific control logic is: when the vehicle's driving mode is in regular driving mode or sports driving mode, and the battery power is lower than the battery power threshold of the pre-cooling function, the pre-cooling function of the vehicle's on-board power battery is activated.

[0059] The pre-cooling temperature threshold of this embodiment includes a pre-cooling start threshold and a pre-cooling exit threshold. The pre-cooling start threshold and the pre-cooling exit threshold of this embodiment can preferably differ by about 2°C. When the maximum temperature of the battery reaches the pre-cooling start threshold, pre-cooling of the on-board power battery is started. When the maximum temperature of the battery reaches the pre-cooling exit threshold, pre-cooling of the on-board power battery is ended. The pre-cooling start threshold of the current SOC interval is equal to the pre-cooling exit threshold of the next adjacent SOC interval, which can avoid the thermal management judgment jump caused by braking recharge and improve the accuracy of thermal management control.

[0060] As shown in Table 1 below, this embodiment provides an example of a stepped pre-cooling temperature threshold as follows:

[0061] Table 1 Example of pre-cooling temperature thresholds for super-fast charging

[0062] Battery level Pre-cooling start threshold (℃) Precooling exit threshold (℃) ＜10％ <![CDATA[T5(26)]]> <![CDATA[T6(24)]]> 10%≤SOC<20% <![CDATA[T4(28)]]> <![CDATA[T5(26)]]> 20%≤SOC<30% <![CDATA[T3(30)]]> <![CDATA[T4(28)]]> 30%≤SOC<40% <![CDATA[T2(32)]]> <![CDATA[T3(30)]]> 40%≤SOC<50% <![CDATA[T1(34)]]> <![CDATA[T2(32)]]>

[0063] In this embodiment, when the battery power threshold of the pre-cooling function is preset, a preset hysteresis value is also included. When the battery power is detected to be lower than the sum of the battery power threshold of the pre-cooling function and the hysteresis value, the pre-cooling function of the vehicle's on-board power battery is activated. The addition of the hysteresis value in this embodiment can avoid the thermal management judgment jump caused by braking recharge, thereby improving the accuracy of thermal management control. The hysteresis value in this embodiment is preferably 2%.

[0064] In this embodiment, the labels of step S1 to step S5 are only used to more clearly express the specific implementation process of the thermal management control method for vehicle pre-cooling, and do not limit the order of the steps.
