[0002] In recent years, the long driving time of pure electric vehicles has been the main concern of customers. The current effective means to increase the driving range is to increase the energy of the battery pack, that is, to increase the battery module. As a result, the control of the battery thermal management system becomes more complex, and the time required for the battery pack temperature to reach another temperature is also longer. In the thermal management performance test of pure electric vehicles, the temperature of the entire vehicle, especially the temperature of the battery pack, needs to be raised or lowered to a certain target temperature. The conventional practice is to place the entire vehicle in a large environmental chamber, set the target temperature of the environmental chamber, and make the temperature of the entire vehicle reach the target temperature by heat exchange with the air in the environmental chamber. However, in this way, the immersion time of the entire vehicle usually needs to be more than 12 hours. Therefore, the energy consumption of the environmental chamber required for the test is very high, and the uniformity of the temperature of the entire vehicle cannot be guaranteed.

Those skilled in the art will understand that Figure 1The hardware structure shown in the figure does not constitute a limitation of the present invention, and may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

The processor 1001 may call the temperature adjustment program stored in the memory 1005 and execute the temperature adjustment method provided in the embodiment of the present invention.

[0045] In a second aspect, an embodiment of the present invention provides a temperature adjustment method.

[0046] In order to more clearly demonstrate the temperature adjustment method provided in the embodiment of the present application, the application scenario of the temperature adjustment method provided in the embodiment of the present application is first introduced.

[0047] The temperature regulation method provided in the embodiment of the present application is applied when conducting a thermal management performance test on a new energy pure electric vehicle, when it is necessary to increase or decrease the temperature of the entire vehicle, especially the temperature of the battery pack, to a certain target temperature.

[0048] In one embodiment, referring to Figure 2 , Figure 2 FIG. 1 is a flow chart of an embodiment of a temperature adjustment method of the present invention. Figure 2 As shown, the temperature adjustment method includes:

[0049] Step S10, obtaining the state of charge and target state of charge of the vehicle battery.

[0050] In this embodiment, the state of charge (SOC) is a relative measure of the energy stored in the battery, which is defined as the ratio of the amount of charge that can be extracted from the battery cell at a specific time point to the total capacity. Before conducting a thermal management test on the vehicle battery, the state of charge of the vehicle battery is obtained, which is equivalent to the initial state of charge of the battery. The target state of charge is the target state of charge to be achieved according to the needs of the test.

[0051] Step S20: determining a battery temperature control strategy according to the state of charge of the vehicle battery and the target state of charge.

[0052] In this embodiment, a corresponding battery temperature control strategy is determined according to the acquired relationship between the initial state of charge and the target state of charge of the vehicle battery.

[0053] Step S30, controlling the battery temperature to reach the target temperature according to the battery temperature control strategy.

[0054] In this embodiment, the battery temperature is made to reach the target temperature according to the corresponding battery temperature control strategy. The target temperature is the target temperature required to be reached for the thermal management test of the new energy pure electric vehicle. Figure 3 , Figure 3 FIG. 1 is a schematic diagram of a vehicle rotating hub discharge according to an embodiment of a temperature adjustment method of the present invention. Figure 3 As shown, the vehicle's OBD (on-board diagnostic system) interface and computer can be connected via a CAN acquisition device, and the vehicle battery temperature can be monitored and acquired in real time via CAN analysis software. In this embodiment, the battery temperature is mainly monitored and used. In addition to the battery temperature, the temperature of the entire vehicle and other key components can also be monitored and controlled to better achieve uniformity between the temperatures of the entire vehicle and key components such as the battery.

[0055] In this embodiment, when conducting a thermal management test on a new energy pure electric vehicle, the initial state of charge and the target state of charge of the vehicle battery are first obtained, and then the corresponding battery temperature control strategy is determined based on the initial state of charge and the target state of charge of the vehicle battery. By using different battery temperature control strategies, the battery temperature can be better controlled to reach the target temperature required for the test, and the vehicle battery can also be better able to reach the target state of charge, and better achieve the uniformity of the temperature of the whole vehicle and key components such as the battery.

[0056] Further, in one embodiment, referring to Figure 4 , Figure 4 for Figure 2 The first detailed flow chart of step S20 is as follows: Figure 4 As shown, step S20 includes:

[0057] Step S201, when the state of charge of the vehicle battery is less than the target state of charge, and the absolute value of the difference between the state of charge of the vehicle battery and the target state of charge is greater than a first preset difference, selecting a first battery temperature control strategy as the battery temperature control strategy;

[0058] Controlling the battery temperature to reach the target temperature according to the battery temperature control strategy includes:

[0059] Step S202, fast charging the vehicle battery until the battery temperature reaches the target temperature.

[0060] In this embodiment, the state of charge of the vehicle battery is less than the target state of charge, and the absolute value of the difference between the state of charge of the vehicle battery and the target state of charge is greater than a first preset difference, which means that the initial state of charge of the vehicle battery is much smaller than the target state of charge. At this time, the initial state of charge of the vehicle battery is small, and the first battery temperature control strategy is selected as the battery temperature control strategy. Correspondingly, the vehicle battery is fast charged to heat up the battery until the battery temperature reaches the target temperature.

[0061] Furthermore, in one embodiment, step S202 includes:

[0062] The vehicle battery is fast charged, and when the state of charge of the vehicle battery reaches the target state of charge, if the battery temperature is lower than the target temperature, the vehicle battery is continued to be fast charged to a new target state of charge, and the new target state of charge is set according to the temperature rise characteristics of the vehicle battery.

[0063] In this embodiment, during the process of fast charging the vehicle battery, when the state of charge of the vehicle battery is fast charged to the target state of charge, if the battery temperature at this time is still lower than the target temperature, the vehicle battery continues to be fast charged to a new target state of charge. The size of the new target state of charge is set according to the characteristics of how fast the vehicle battery temperature rises when the vehicle battery is fast charged. For example, the temperature of the vehicle battery in this test rises faster during fast charging, and a smaller new target state of charge can be set accordingly.

[0064] Furthermore, in one embodiment, step S202 further includes:

[0065] The vehicle battery is fast charged. When the state of charge of the vehicle battery reaches the target state of charge, if the battery temperature is greater than the target temperature, the battery cooling function is turned on until the battery temperature reaches the target temperature, and then the battery cooling function is turned off.

[0066] In this embodiment, during the fast charging process of the vehicle battery, when the charge state of the vehicle battery is fast charged to the target charge state, if the battery temperature at this time is greater than the target temperature, the battery cooling function is turned on to lower the battery temperature. When the battery temperature is lowered to the target temperature, the battery cooling function is turned off.

[0067] Further, in one embodiment, referring to Figure 5 , Figure 5 for Figure 2 The second detailed flow chart of step S20 is as follows: Figure 5 As shown, step S20 also includes:

[0068] Step S203, when the state of charge of the vehicle battery is greater than the target state of charge, and the absolute value of the difference between the state of charge of the vehicle battery and the target state of charge is greater than a second preset difference, selecting a second battery temperature control strategy as the battery temperature control strategy;

[0069] Controlling the battery temperature to reach the target temperature according to the battery temperature control strategy includes:

[0070] Step S204 , controlling the vehicle to run at a preset speed to discharge the vehicle battery until the battery temperature reaches a target temperature.

[0071] In this embodiment, the state of charge of the vehicle battery is greater than the target state of charge, and the absolute value of the difference between the state of charge of the vehicle battery and the target state of charge is greater than the second preset difference, which means that the initial state of charge of the vehicle battery is much greater than the target state of charge. At this time, the initial state of charge of the vehicle battery is large, and the second battery temperature control strategy is selected as the battery temperature control strategy. Correspondingly, the vehicle is controlled to run at a preset speed to discharge the vehicle battery and heat the battery until the battery temperature reaches the target temperature. Continue to refer to Figure 3 , Figure 3 FIG. 1 is a schematic diagram of a vehicle rotating hub discharge according to an embodiment of a temperature adjustment method of the present invention. Figure 3 As shown, the vehicle can be placed on the vehicle hub to facilitate adjustment of the vehicle speed and testing of the vehicle and battery.

[0072] Further, in one embodiment, controlling the vehicle to run at a preset speed to discharge the vehicle battery until the battery temperature reaches a target temperature includes:

[0073] The vehicle is controlled to run at a preset speed to discharge the vehicle battery. When the state of charge of the vehicle battery reaches the target state of charge, if the battery temperature is lower than the target temperature, the vehicle battery is fast charged until the state of charge of the vehicle battery reaches a new target state of charge. The new target state of charge and the preset speed are set according to the temperature rise characteristics of the vehicle battery.

[0074] In this embodiment, the vehicle is controlled to run at a preset speed to discharge the vehicle battery. When the real-time state of charge of the vehicle battery reaches the target state of charge, if the battery temperature is still lower than the target temperature at this time, the vehicle battery is switched to fast charging until the state of charge of the vehicle battery reaches the new target state of charge. Because the vehicle cannot be fast charged at the same time when it runs at a certain speed, the battery temperature is still lower than the target temperature when the real-time state of charge of the vehicle battery reaches the target state of charge. In this case, if the battery temperature continues to be increased by running the vehicle at the preset speed, the vehicle battery may be insufficient, thereby affecting the needs of the test. The greater the vehicle speed, the greater the discharge current of the vehicle battery and the faster the battery temperature rises. The preset speed is set according to the characteristics of the vehicle battery temperature increase speed. For example, the vehicle battery temperature rises faster in this test, and a smaller preset speed can be set accordingly.

[0075] Further, in one embodiment, referring to Figure 6 , Figure 6 for Figure 2 The third detailed flow diagram of step S20 is as follows: Figure 6 As shown, step S20 also includes:

[0076] Step S205, when the absolute value of the difference between the state of charge of the vehicle battery and the target state of charge is less than a third preset difference, selecting a third battery temperature control strategy as the battery temperature control strategy;

[0077] Controlling the battery temperature to reach the target temperature according to the battery temperature control strategy includes:

[0078] Step S206, controlling the vehicle to run at a preset speed to discharge the vehicle battery, or to fast charge the vehicle battery, until the battery temperature reaches the target temperature.

[0079] In this embodiment, the absolute value of the difference between the state of charge of the vehicle battery and the target state of charge is less than the third preset difference, which means that the initial state of charge of the vehicle battery is not much different from the target state of charge. The third battery temperature control strategy is selected as the battery temperature control strategy. Correspondingly, the vehicle can be controlled to run at a preset speed to discharge the vehicle battery, or the vehicle battery can be fast charged until the battery temperature reaches the target temperature.

[0080] In this embodiment, when conducting a thermal management test on a new energy pure electric vehicle, the initial state of charge and the target state of charge of the vehicle battery are first obtained, and then the corresponding battery temperature control strategy is determined based on the initial state of charge and the target state of charge of the vehicle battery. By using different battery temperature control strategies, the battery temperature can be better controlled to reach the target temperature required for the test, and the vehicle battery can also be better able to reach the target state of charge. By monitoring the temperature of the entire vehicle and multiple key components other than the battery and combining the use of the battery cooling function, the uniformity of the temperature of the entire vehicle and key components such as the battery can be better achieved. Compared with the existing technology of heating the entire vehicle and the battery by using an environmental chamber, it has the advantages of fast heating, low energy consumption and good uniformity.
