Example 1
Fig. 1 is a flowchart of a power battery heating method according to a first embodiment of the present invention, where the method may be performed by a power battery heating device, which may be implemented in hardware and/or software, and may be configured in a terminal and/or a server, where the power battery heating device heats a power battery of a vehicle using heat generated by a power accessory of the vehicle. As shown in fig. 1, the method includes:
s110, acquiring temperature information corresponding to the vehicle power fittings.
In the present embodiment, the vehicle power fitting may be at least one unit constituting the whole of the vehicle, and these units are used to realize the power function of the vehicle. The vehicle power accessories may include a variety of accessories, and may alternatively include engine accessories, driveline accessories, brake system accessories, steering system accessories, and the like. The temperature information may be information indicative of heat generated by the vehicle power fitting during operation. In general, during running of a vehicle, or when the vehicle is in a parking state and is not powered down, corresponding accessories included in the vehicle may be always in an operating state, and when the vehicle power accessory is in an operating state, a large amount of heat may be generated, and even the operation may be stopped due to the excessive heat.
In practical application, when the vehicle power fitting is in the working process, the heat generated by the vehicle power fitting can be continuously detected, so that the temperature information corresponding to the vehicle power fitting can be determined.
Optionally, acquiring temperature information corresponding to a vehicle power accessory includes: the temperature detection is performed on the vehicle power fitting based on a temperature sensor preset on the vehicle power fitting to obtain temperature information corresponding to the vehicle power fitting.
The temperature sensor is a sensor capable of sensing temperature and converting the sensed temperature into a usable output signal.
In a specific implementation, a temperature sensor CAN be arranged on a vehicle power fitting in advance, and is connected with an electronic control unit (Electronic Control Unit, ECU) arranged in the vehicle through a vehicle CAN bus, when the vehicle power fitting is in a working process, the temperature sensor CAN be used for detecting the temperature of the vehicle power fitting, the detected temperature is converted into temperature information in a usable output signal form based on the temperature sensor, and the temperature information is sent to the vehicle ECU, so that the vehicle ECU CAN analyze the working condition of the vehicle power fitting based on the temperature information after receiving the temperature information corresponding to the vehicle power fitting.
And S120, determining a pipeline communication state between the vehicle power accessory and the vehicle power battery based on the temperature information.
In this embodiment, the vehicle power battery may be a power source that provides a source of power for the vehicle. The vehicle power battery may be any type of battery, and alternatively may be a lithium battery, a lead-acid battery, other types of batteries, and the like. In practical applications, the piping may be disposed in advance inside the vehicle, and the disposed piping may pass through the vehicle power fitting, the vehicle power battery, and the vehicle heating device, and further, the heat radiation process to the vehicle power fitting and the heating process to the vehicle power battery may be performed by controlling the communication state of the disposed piping. Wherein the conduit may be a flow conduit for liquid transfer. The pipeline can be made of any material, and can be made of rubber, nylon or metal. The line communication state may be information indicative of a line communication condition between the vehicle power fitting and the vehicle power battery. Alternatively, the line communication state may include line communication or line non-communication. In this connection, a line connection is understood to mean a line connection between any two devices, i.e. a liquid in a line can flow through one device and then through the other device, or a line connection is understood to mean a liquid flow between the two devices. Conversely, a conduit is not connected to and from any two devices, or a conduit is not connected to and from any two devices, i.e., liquid in the conduit may not flow through one device after the other.
In practical applications, after obtaining the temperature information corresponding to the vehicle power fitting, the temperature information may be subjected to a judgment analysis to determine, according to the result of the judgment analysis of the temperature information, the communication state of the pipeline disposed between the vehicle power fitting and the vehicle power battery.
Optionally, determining a state of pipe communication between the vehicle power accessory and the vehicle power battery based on the temperature information includes: if the temperature information is greater than or equal to a preset temperature threshold value, determining a pipeline communication state between the vehicle power accessory and the vehicle power battery as pipeline communication; and if the temperature information is smaller than the preset temperature threshold value, determining that the pipeline is not communicated in the pipeline communication state between the vehicle power accessory and the vehicle power battery.
In this embodiment, the preset temperature threshold may be a preset threshold when the vehicle power fitting stops working due to high temperature. The preset temperature threshold may be set according to the material of the vehicle power fitting and other parameters. Alternatively, the preset temperature threshold may be 30 degrees celsius, 40 degrees celsius, 50 degrees celsius, or the like.
In a specific implementation, when the vehicle power accessory is in a working process, the temperature sensor arranged on the vehicle power accessory continuously collects temperature information of the vehicle power accessory and continuously sends the temperature information to the vehicle ECU, when the vehicle ECU receives the temperature information corresponding to the vehicle power accessory, the received temperature information can be compared with a preset temperature threshold value which is arranged in the ECU in advance, and if the temperature information is smaller than the preset temperature threshold value, the pipeline communication state between the vehicle power accessory and the vehicle power battery is determined as that the pipelines are not communicated; if the temperature information is greater than or equal to the preset temperature threshold, the pipeline communication state between the vehicle power accessory and the vehicle power battery can be determined to be pipeline communication.
In practical application, when the vehicle power fitting is in a working process, the heat generated by the vehicle power fitting continuously rises, and correspondingly, the temperature information corresponding to the vehicle power fitting also continuously rises, so that when the vehicle power fitting is just in a working process, the temperature information corresponding to the vehicle power fitting is smaller than a preset temperature threshold value, at the moment, a pipeline arranged between the vehicle power fitting and a vehicle power battery is in a non-communication state, further, when the working time of the vehicle power fitting is prolonged, the generated heat continuously rises, the corresponding temperature information continuously rises, and when the temperature information corresponding to the vehicle power fitting is detected to be larger than or equal to the preset temperature threshold value, a pipeline control instruction can be generated, so that the pipeline between the vehicle power fitting and the vehicle power battery is controlled to be switched from the non-communication state to the communication state based on the pipeline control instruction.
It should be noted that, the manner of switching the pipeline between the vehicle power fitting and the vehicle power battery from the non-communication state to the communication state may include various manners, and alternatively, a three-way valve may be disposed on the pipeline where the vehicle power fitting and the vehicle power battery are located, and the three-way valve is controlled to switch the pipeline between the vehicle power fitting and the vehicle power battery from the non-communication state to the communication state.
Optionally, if the temperature information is greater than or equal to a preset temperature threshold, determining the pipeline communication state between the vehicle power accessory and the vehicle power battery as pipeline communication includes: if the detected temperature information is greater than or equal to a preset temperature threshold, the first liquid inlet and the second liquid inlet of the three-way valve are controlled to be opened so as to be communicated with a pipeline between the vehicle power accessory and the vehicle power battery based on the first liquid inlet and the second liquid inlet.
In this embodiment, the three-way valve may be a valve device in which three inlets and outlets are all connected to a pipeline. The first liquid inlet and outlet may be any one of three inlet and outlet of a three-way valve. Alternatively, the first liquid inlet and outlet may be a liquid inlet and outlet connected to a pipeline where the vehicle power fitting is located. The second liquid inlet and outlet may be any one of three inlet and outlet of the three-way valve. Alternatively, the second liquid inlet and outlet may be a liquid inlet and outlet connected to a pipeline where the vehicle power battery is located.
In a specific implementation, when the temperature information corresponding to the vehicle power accessory is detected to be greater than or equal to a preset temperature threshold, a first control instruction of the three-way valve can be generated, and based on the first control instruction of the three-way valve, the first liquid inlet and the second liquid inlet and outlet of the three-way valve are controlled to be opened, and then, based on the opened first liquid inlet and outlet and the opened second liquid inlet and outlet, a pipeline between the vehicle power accessory and the vehicle power battery can be communicated.
By way of example, the process of line communication between a vehicle power fitting and a vehicle power battery may be described in connection with fig. 2: the position of the dashed frame is the specific position of the three-way valve, and the arrow direction of each connecting line in fig. 2 is the flow direction of the circulating flowing liquid. When the temperature information of the vehicle power battery is detected to be greater than or equal to a preset temperature threshold value, the first liquid inlet and outlet 1 and the second liquid inlet and outlet 2 of the three-way valve are controlled to be opened, and further, a pipeline between the vehicle power accessory and the vehicle power battery is communicated according to the opened first liquid inlet and outlet 1 and second liquid inlet and outlet 2.
S130, determining heat change information of the vehicle power battery based on the pipeline communication state.
In this embodiment, the heat variation information may be information that characterizes a variation in temperature of the vehicle power battery.
In practical application, when the temperature information corresponding to the vehicle power accessory is detected to be greater than or equal to the preset temperature threshold, the pipeline communication state between the vehicle power accessory and the vehicle power battery can be determined to be pipeline communication according to the temperature information, and then the vehicle power battery is subjected to heating treatment through the pipeline in the pipeline communication state so as to determine the heat change information of the vehicle power battery.
Optionally, determining the thermal variation information of the vehicle power battery based on the pipeline communication state includes: when the pipe communication state is pipe communication, heat information of the vehicle power fitting is determined based on circulating fluid in a pipe between the vehicle power fitting and the vehicle power battery, and the vehicle power battery is heated based on the heat information to determine heat change information of the vehicle power battery.
In this embodiment, the circulating flowing liquid may be a liquid circulating in a pipeline. The circulating fluid may be any liquid, alternatively liquid water. The thermal information may be indicative of the heat generated by the vehicle power fitting during operation.
In a specific implementation, a pipeline where the vehicle power accessory and the vehicle power battery are located can be connected with the circulating water tank and the water pump in advance, circulating flowing liquid with preset capacity can be stored in the circulating water tank in advance, in a practical application process, circulating flowing liquid in the circulating water tank can be pumped through the water pump so that the circulating flowing liquid circulates in the pipeline where the vehicle power accessory and the vehicle power battery are located, when the circulating flowing liquid flows through the vehicle power accessory, the circulating flowing liquid can be subjected to heating treatment according to heat information of the vehicle power accessory so as to take away heat generated in the working process of the vehicle power accessory, further, the heated circulating flowing liquid continues to flow in the pipeline, when the heated circulating flowing liquid flows through the vehicle power battery, the vehicle power battery can be subjected to heating treatment according to the heated circulating flowing liquid, heat change information of the vehicle power battery can be determined, and due to the fact that the circulating flowing liquid circulates in the pipeline, the heating process of the circulating flowing liquid and the heating process of the vehicle power battery can be repeatedly executed, and after each time the circulating flowing through the vehicle power battery, the heat change information of the vehicle power battery can be determined.
Further, after the circulating flowing liquid flows through the vehicle power battery each time, the heat change information of the vehicle power battery is determined, and when the difference value between any one heat change information and the previous heat change information is detected to be smaller than or equal to a preset difference value threshold value, a three-way valve closing instruction can be generated, so that the first liquid inlet and the second liquid inlet of the three-way valve are closed based on the three-way valve closing instruction, and a pipeline between the vehicle power accessory and the vehicle power battery is restored to a pipeline non-communication state. The preset difference threshold may be a small value, alternatively, may be 0.1, 0.2, or 0.3, etc.
In practical application, when the temperature information corresponding to the vehicle power battery exceeds a preset temperature threshold value, the vehicle power battery can be heated based on heat generated by the vehicle power battery in the working process, so that the vehicle power battery can be heated while heat is radiated to vehicle power accessories, the energy utilization rate is improved, and the working mileage of the unmanned vehicle is prolonged.
In this embodiment, when the temperature information corresponding to the vehicle power battery does not exceed the preset temperature threshold, the vehicle power battery may be heated by the vehicle-mounted heating device, so as to ensure that the vehicle power battery may operate normally in a low-temperature environment.
Based on the above, the above technical means further includes: and if the temperature information is smaller than the preset temperature threshold value, controlling the second liquid inlet and the third liquid inlet and outlet of the three-way valve to be opened so as to communicate a pipeline between the vehicle power battery and the vehicle-mounted heating device based on the second liquid inlet and outlet and the third liquid inlet and outlet.
In this embodiment, the third liquid inlet and outlet may be any one of three inlet and outlet of the three-way valve. Optionally, the third liquid inlet and outlet may be a liquid inlet and outlet connected to a pipeline where the vehicle heating device is located. The on-vehicle heating device may be a device provided in the vehicle for providing thermal energy to the vehicle interior and corresponding components of the vehicle. The vehicle-mounted heating device has the main function of providing more heat energy for the vehicle in a low-temperature environment, so that key components such as an engine, a motor, a power battery and the like can constantly run. The vehicle heating device may be any heating device, and alternatively, may be a PTC (Positive Temperature Coefficient) heater. PTC means a positive temperature coefficient, generally referring to a semiconductor or component with a very large positive temperature coefficient, such as a PTC thermistor.
In practical application, at the stage when the vehicle power fitting just begins to work, or after the vehicle power fitting is subjected to heat dissipation treatment, temperature information corresponding to the vehicle power fitting is smaller than a preset temperature threshold, at this time, if the vehicle power battery is to be heated, the vehicle power battery can be heated based on the vehicle heating device, specifically, when the temperature information corresponding to the vehicle power fitting is detected to be smaller than the preset temperature threshold, a second control instruction of the three-way valve is generated, and the second liquid inlet and the third liquid inlet of the three-way valve are controlled to be opened according to the second control instruction of the three-way valve, and then a pipeline between the vehicle power battery and the vehicle heating device can be communicated according to the second liquid inlet and the third liquid inlet and outlet after being opened, and meanwhile, when the temperature information corresponding to the vehicle power fitting is detected to be smaller than the preset temperature threshold, a heating device opening instruction can be generated, so that the vehicle heating device is controlled to be opened based on the heating device opening instruction, and the vehicle heating device is enabled to be in a working state.
For example, with continued reference to fig. 2, when it is detected that the temperature information of the vehicle power fitting is less than the preset temperature threshold, the second liquid inlet and outlet 2 and the third liquid inlet and outlet 3 of the three-way valve are controlled to be opened, and further, the pipeline between the vehicle power battery and the vehicle-mounted heating device is communicated according to the opened second liquid inlet and outlet 2 and third liquid inlet and outlet 3.
In practical application, because the pipeline between the vehicle power battery and the vehicle-mounted heating device is also connected with the circulating water tank and the water pump, when the vehicle power battery is heated based on the vehicle-mounted heating device, the circulating flowing liquid which circularly flows in the pipeline can be heated by utilizing the vehicle-mounted heating device, so that the heated circulating flowing liquid flows in the pipeline, and when the heated circulating flowing liquid flows through the vehicle power battery, the vehicle power battery can be heated.
Based on the above, the above technical means further includes: under the condition that the pipeline communication state between the vehicle power battery and the vehicle-mounted heating device is pipeline communication, the circulating flowing liquid in the pipeline between the vehicle-mounted heating device and the vehicle power battery is heated based on the vehicle-mounted heating device, so that the vehicle power battery is heated based on the heated circulating flowing liquid, and the heat change information of the vehicle power battery is determined.
In a specific implementation, a pipeline where the vehicle power battery and the vehicle-mounted heating device are located can be connected with the circulating water tank and the water pump in advance, circulating flowing liquid with preset capacity can be stored in the circulating water tank in advance, in a practical application process, circulating flowing liquid in the circulating water tank can be pumped through the water pump so that the circulating flowing liquid circulates in the pipeline between the vehicle power battery and the vehicle-mounted heating device, when the circulating flowing liquid flows through the vehicle-mounted heating device, the circulating flowing liquid can be subjected to heating treatment through the vehicle-mounted heating device, further, when the heated circulating flowing liquid flows through the vehicle power battery, the vehicle power battery can be subjected to heating treatment according to the heated circulating flowing liquid, and heat change information of the vehicle power battery is determined.
Further, after the circulating flowing liquid flows through the vehicle power battery each time, the heat change information of the vehicle power battery is determined, and when the difference value between any one heat change information and the previous heat change information is detected to be smaller than or equal to a preset difference value threshold value, a three-way valve closing instruction can be generated, so that the second liquid inlet and outlet of the three-way valve and the third liquid inlet and outlet of the three-way valve are closed based on the three-way valve closing instruction, and a pipeline between the vehicle power battery and the vehicle-mounted heating device is restored to a pipeline non-communication state. The preset difference threshold may be a small value, alternatively, may be 0.1, 0.2, or 0.3, etc.
According to the technical scheme, the temperature information corresponding to the vehicle power accessory is obtained, the pipeline communication state between the vehicle power accessory and the vehicle power battery is further determined based on the temperature information, and finally, the heat change information of the vehicle power battery is determined based on the pipeline communication state, so that the problems that in the prior art, energy waste and shortening the working mileage of a vehicle are caused by the fact that the power battery can be heated by using the energy of the power battery after the vehicle is electrified are solved, the vehicle power battery is heated by using the heat generated by the vehicle power accessory, the effect of heating the vehicle power battery while radiating the vehicle power accessory is achieved, and the utilization rate of the whole vehicle energy is improved.
