[0050] According to an embodiment of the present invention, there is provided a method embodiment for controlling an in-vehicle power battery management system. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0051] This method embodiment can be executed in an electronic device or a similar computing device that includes a memory and a processor in a vehicle. Taking running on the electronic device of the vehicle as an example, as Figure 1 shown, the electronic device of the vehicle may include one or more processors 102 (the processor may include, but is not limited to, a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processing (DSP) chip, a microprocessor (MCU), a programmable logic device (FPGA), a neural network processor (NPU), a tensor processor (TPU), an artificial intelligence (AI) type processor, etc.) and a memory 104 for storing data.

[0055] In this embodiment, a method for controlling an on-vehicle power battery management system running on the electronic device of the above vehicle is provided.Figure 2 is a flowchart of a method for controlling an in-vehicle power battery management system according to an embodiment of the present invention. As Figure 2 shown, the process includes the following steps: Step S1: Collect the first battery temperature generated by a sensor sensing the in-vehicle power battery. Step S2: Compare the first battery temperature with a first temperature threshold to obtain a first comparison result, where the first temperature threshold is a temperature threshold initialized when the cooling control of the in-vehicle power battery is turned on and preset. Step S3: Generate a control instruction set under the condition that the first comparison result meets certain conditions. The control instruction set is used to control the in-vehicle power battery management system to execute a target working mode, where the target working mode includes at least one of the following: normal cooling working mode, solar-assisted cooling working mode, solar combined heating working mode, normal heating working mode, solar-assisted heating working mode, in-vehicle auxiliary power charging working mode. Among them, the first comparison result refers to: the first battery temperature is greater than the first temperature threshold, or the first battery temperature is less than or equal to the first temperature threshold.

[0056] In the embodiment of the present application, by comparing the first battery temperature of the in-vehicle power battery with the first temperature threshold, a control instruction set is generated according to the obtained first comparison result. The control instruction set is used to control the in-vehicle power battery management system to execute the target working mode. According to the working temperature of the in-vehicle power battery, the working mode of the in-vehicle power battery temperature control system is flexibly switched, and solar energy and other auxiliary power sources are used to provide electric energy for the in-vehicle power battery temperature control system, so that the in-vehicle power battery works within a suitable temperature range, avoiding low charge and discharge efficiency of the in-vehicle power battery caused by too low working temperature, and even causing irreversible damage to the battery body. In addition, using solar energy and other auxiliary power sources to provide electric energy for the in-vehicle power battery temperature control system reduces the frequency of using the power of the in-vehicle power battery itself for heating, reduces the power consumption of the in-vehicle power battery, and prolongs the cycle life of the in-vehicle power battery.

[0057] Optionally, in step S3, the following execution steps are further included: Obtain the first working duration of the target working mode. When the first working duration meets the first preset condition, collect the second battery temperature of the in-vehicle power battery, compare the second battery temperature with the first temperature threshold to obtain a second comparison result. When the second comparison result meets the second preset condition, detect the target working mode within a preset time period to obtain a detection result. Generate a first target instruction in the control instruction set according to the detection result. The first target instruction is used to control the current target working mode to stop working or continue working. Among them, the second comparison result refers to: the second battery temperature is greater than the first temperature threshold, or the second battery temperature is less than or equal to the first temperature threshold. The second preset condition refers to one of the situations in the second comparison result.

[0058] Through the above steps, a fixed duration and preset conditions are set for the cyclic execution of the target working mode, enabling real-time control of the stop or continuation of the target working mode, and timely providing the required electrical energy for the temperature control system of the vehicle-mounted power battery.

[0059] Optionally, before comparing the first battery temperature with the first temperature threshold, it further includes: collecting the actual working voltage of the solar charging device. Comparing the collected actual working voltage of the solar charging device with the effective working voltage of the solar charging device to obtain a third comparison result. When the third result meets the third preset condition, a second target instruction in the control instruction set is generated, and the second target instruction is used to control the solar charging device to supply electrical energy to the target device, where the target device includes at least one of the following: battery auxiliary heating device, vehicle-mounted power battery, battery main heating device, vehicle-mounted auxiliary power supply, power motor. The third comparison result refers to: the collected actual working voltage of the solar charging device is greater than the effective working voltage of the solar charging device, or the collected actual working voltage of the solar charging device is less than or equal to the effective working voltage of the solar charging device. The third preset condition refers to: the collected actual working voltage of the solar charging device is greater than the effective working voltage of the solar charging device.

[0060] In the above steps, when the actual working voltage of the collected solar charging device meets the preset condition, the solar charging device is controlled to supply electrical energy to the target device, and the target device then provides the required electrical energy for the temperature control system of the vehicle-mounted power battery according to the actual working conditions. Indirectly using solar energy to provide electrical energy for the temperature control system of the vehicle-mounted power battery reduces the frequency of using the vehicle-mounted power battery's own power for heating, reduces the power consumption of the vehicle-mounted power battery, and prolongs the cycle life of the vehicle-mounted power battery.

[0061] Optionally, a control instruction set is generated based on the first comparison result, including: comparing the first battery temperature with a second temperature threshold, where the second temperature threshold is a temperature threshold initialized for the vehicle-mounted power battery when the cooling control is turned on. When the first battery temperature is greater than the second temperature threshold, the actual working voltage of the solar charging device is collected, and the collected actual working voltage of the solar charging device is compared with the effective working voltage of the solar charging device to obtain a fourth comparison result. When the fourth comparison result meets a fourth preset condition, a third target instruction in the control instruction set is generated, and the third target instruction is used to control the vehicle-mounted power battery management system to execute the normal cooling working mode or the solar-assisted cooling working mode. Among them, the fourth comparison result refers to: the collected actual working voltage of the solar charging device is greater than the effective working voltage of the solar charging device, or the collected actual working voltage of the solar charging device is less than or equal to the effective working voltage of the solar charging device. The fourth preset condition refers to one of the situations in the fourth comparison result.

[0062] In the above steps, both the first temperature threshold and the second temperature threshold are temperature thresholds initialized for the vehicle-mounted power battery when the cooling control is turned on. The first battery temperature is accurately determined within a temperature range through two temperature comparisons, enabling the vehicle-mounted power battery management system to select a more precise target working mode and a more reasonable power supply mode for the temperature control system of the vehicle-mounted power battery.

[0063] Optionally, the second working duration of the normal cooling working mode is further obtained. When the second working duration meets a fifth preset condition, the actual working voltage of the solar charging device and the second battery temperature of the vehicle-mounted power battery are collected. When the actual working voltage of the solar charging device and the second battery temperature meet the fifth preset condition, the target working mode of the current vehicle-mounted power battery management system is obtained, and it is determined whether the current target working mode is the same as the normal cooling working mode. If not, a fourth target instruction in the control instruction set is generated, and the fourth target instruction is used to control the normal cooling working mode to stop working. In the above steps, by comparing and determining the current target working mode, the automatic cycle and stop of the target working mode are achieved. Among them, the fifth preset condition refers to the numerical value of the system operation cycle.

[0064] Optionally, based on the first comparison result, a second target instruction is generated, including: obtaining a second temperature threshold, where the second temperature threshold is a temperature threshold initialized for the vehicle-mounted power battery when the cooling control is turned on. When the first battery temperature is less than or equal to the first temperature threshold and the first battery temperature is less than or equal to the second temperature threshold, the first battery temperature and the actual working voltage of the solar charging device are respectively compared with a third temperature threshold and the effective working voltage of the solar charging device to obtain a sixth comparison result, where the third temperature threshold is a temperature threshold initialized for the vehicle-mounted power battery when the heating control is turned on. A second target instruction is generated based on the sixth comparison result. Specifically, when the first battery temperature is less than the third temperature threshold and the actual working voltage of the solar charging device is greater than the effective working voltage of the solar charging device, the ninth target instruction in the control instruction set is generated, and the ninth target instruction is used to control the vehicle-mounted power battery management system to execute the solar combined heating working mode.

[0065] In the above steps, when the first battery temperature is less than or equal to both the first temperature threshold and the second temperature threshold, the third temperature threshold is set. By comparing with the third temperature threshold, the temperature range of the first battery temperature is further judged, which helps to select a more accurate target working mode for the vehicle-mounted power battery management system and a more reasonable power supply mode for the temperature control system of the vehicle-mounted power battery.

[0066] Optionally, a fourth temperature threshold is further obtained, where the fourth temperature threshold is a temperature threshold initialized for the vehicle-mounted power battery when the heating control is turned on. When the first battery temperature is greater than or equal to the third temperature threshold and the first battery temperature is less than the fourth temperature threshold, it is judged whether the actual working voltage of the solar charging device is greater than the effective working voltage of the solar charging device. If so, the fifth target instruction in the control instruction set is generated, and the fifth target instruction is used to control the vehicle-mounted power battery management system to execute the solar assisted heating working mode. If not, the sixth target instruction in the control instruction set is generated, and the sixth target instruction is used to control the vehicle-mounted power battery management system to execute the normal heating working mode.

[0067] In the above steps, on the premise of setting the first temperature threshold, the second temperature threshold, and the third temperature threshold, there is a preset fourth temperature threshold. The first battery temperature is sequentially compared with the above four temperature thresholds to accurately judge the range of the first battery temperature, which helps to select a more accurate target working mode for the vehicle-mounted power battery management system and a more reasonable power supply mode for the temperature control system of the vehicle-mounted power battery.

[0068] Optionally, when the first battery temperature is greater than or equal to the third temperature threshold and the first battery temperature is greater than or equal to the fourth temperature threshold, obtain the state of charge of the vehicle-mounted auxiliary power supply. When the state of charge of the vehicle-mounted auxiliary power supply is less than the lower limit threshold of the state of charge for charging the vehicle-mounted auxiliary power supply and the actual operating voltage of the solar charging device is greater than the effective operating voltage of the solar charging device, generate the seventh target instruction in the control instruction set. The seventh target instruction is used to control the vehicle-mounted power battery management system to execute the vehicle-mounted auxiliary power supply charging working mode. Otherwise, generate the eighth target instruction in the control instruction set. The eighth target instruction is used to control the vehicle-mounted power battery management system to enter the standby mode.

[0069] In the above steps, by judging the comparison condition between the state of charge of the vehicle-mounted auxiliary power supply and the lower limit threshold of the state of charge for charging, direct charging of the vehicle-mounted auxiliary power supply by solar energy and indirect power supply to the temperature control system of the vehicle-mounted power battery by solar energy are realized.

In addition, the vehicle-mounted power battery temperature control system 1 is connected to the vehicle-mounted power battery management system 7 through signal lines to transmit control signals and data signals to each other.

[0198] As Figure 16As shown, when the in-vehicle power battery power temperature controller 1-1 enters the normal cooling working mode, it executes the control flow step S0101-03-01 of the normal cooling working mode of the in-vehicle power battery power temperature controller: The in-vehicle power battery power temperature controller 1-1 supplies power to each actuator of the in-vehicle power battery temperature control system 1 by controlling the relevant switch circuits and using the in-vehicle auxiliary power supply 6. The in-vehicle power battery temperature control system 1 exchanges heat using the power battery power cooling pipeline radiator 1-10 to reduce the temperature of the coolant in the in-vehicle power battery temperature control system 1. Open the first valve 1-4 of the power battery power heating pipeline, the bypass valve 1-8 of the heat exchange device of the power battery power forced cooling pipeline, and the cut-off valve 1-9 of the power battery power cooling pipeline radiator. Close the bypass valve 1-7 of the power battery power cooling pipeline radiator, the cut-off valve 1-12 of the heat exchange device of the power battery power forced cooling pipeline, the second valve 1-14 of the power battery power heating pipeline, the third valve 1-16 of the power battery power heating pipeline, and the fourth valve 1-18 of the power battery power heating pipeline.

If, on this basis, the on-vehicle power battery management system 7 detects that the cooling capacity of the on-vehicle power battery temperature control system 1 is still insufficient, then the cut-off valve 1-12 of the heat exchange device of the power battery power forced cooling pipeline is opened, the bypass valve 1-8 of the heat exchange device of the power battery power forced cooling pipeline is closed, and the flow direction of the coolant in the on-vehicle power battery temperature control system 1 is changed to: flowing out from the on-vehicle power battery power coolant storage device 1-3, passing through the first valve 1-4 of the power battery power heating pipeline, the coolant pipeline of the battery main heating device 1-5, the circulating pump 1-6 of the power battery power temperature control pipeline, the cut-off valve 1-9 of the radiator of the power battery power cooling pipeline, the radiator 1-10 of the power battery power cooling pipeline, the cut-off valve 1-12 of the heat exchange device of the power battery power forced cooling pipeline, the on-vehicle power battery power forced cooling heat exchange device 1-13, flowing into the cooling pipeline in the on-vehicle power battery power 8, and finally flowing back to the on-vehicle power battery power coolant storage device 1-3.

It operates when the vehicle speed is too low or the in-vehicle power battery management system 7 detects that the heat exchange capacity of the power battery power cooling pipeline radiator 1-10 is insufficient (for example, after the in-vehicle power battery power temperature controller 1-1 maintains the normal cooling working mode for a period of time, the working temperature of the battery cells in the in-vehicle power battery power 8 still does not decrease or continues to rise), to strengthen the air flow rate and air volume flowing through the power battery power cooling pipeline radiator 1-10, so as to enhance the heat exchange capacity of the power battery power cooling pipeline radiator 1-10.
