Description

Technical Field

[0001] This invention relates to the field of vehicle battery swapping technology, and more specifically, to a battery de-icing system, a vehicle having the same, and a battery swapping method applied to the vehicle. Background Technology

[0002] Currently, electric vehicles take a long time to charge, even DC charging takes at least half an hour, especially for commercial vehicles. The advent of battery swapping technology has solved the contradiction between long driving range requirements and long charging time. The battery pack can be replaced in just 1 to 2 minutes, saving charging time. Battery swapping electric vehicles have great development prospects.

[0003] Most battery-swapping vehicles on the market are designed for battery swapping only based on demand. However, some vehicles themselves may encounter situations that prevent battery swapping. For example: 1. After rain or snow in northern regions, the power battery and swapping frame of some vehicles may freeze, preventing battery pack replacement at the swapping station. The vehicle must remain near the station waiting for the ambient temperature to rise so the ice and snow between the battery and frame can melt, severely impacting swapping efficiency and causing time and financial losses for users; 2. Before a vehicle is taken to a swapping station, drivers and passengers cannot predict whether the battery can be swapped. The vehicle can only attempt a swap at the station, and during this trial, some battery locking mechanisms may fail to disengage, preventing the vehicle from being swapped or reset; 3. If de-icing is performed manually, workers cannot guarantee that the battery and some locking mechanisms will not be touched during the de-icing process. The battery may detach during de-icing, or the battery casing may be damaged, posing a safety risk.

[0004] There is currently no effective solution to the technical problem of battery locking mechanism icing causing inconvenience in subsequent battery swapping. Summary of the Invention

[0005] The main objective of this invention is to provide a battery de-icing system, a vehicle having the same, and a battery swapping method for vehicles, in order to solve the technical problem of inconvenience in subsequent battery swapping caused by icing of the battery locking mechanism in the prior art.

[0006] To achieve the above objectives, according to one aspect of the present invention, a battery de-icing system is provided, comprising: a battery mounting frame having a mounting cavity, an annular partition disposed within the battery mounting frame to divide the mounting cavity into a battery mounting cavity and an annular heating cavity, the battery mounting cavity being used to mount a power battery, the power battery being disposed with a gap from the annular partition; a battery locking mechanism connected to the annular partition, the battery locking mechanism having a working state of locking the power battery to the battery mounting frame and a releasing state of releasing the power battery from the battery mounting frame; and a de-icing circuit disposed within the annular heating cavity, the de-icing circuit being connected to the vehicle's overall heating system, the heating liquid of the vehicle's heating system being able to circulate within the de-icing circuit to de-ic the battery mounting frame.

[0007] Furthermore, the battery de-icing system also includes: an infrared sensor connected to an annular separator. There are multiple infrared sensors, which are used to detect whether there are foreign objects between the annular separator and the power battery. Foreign objects include at least ice and mud.

[0008] Furthermore, there are multiple battery locking mechanisms, with at least one battery locking mechanism provided between adjacent infrared sensors.

[0009] Furthermore, there are multiple battery locking mechanisms, and at least one infrared sensor is provided between adjacent battery locking mechanisms.

[0010] Furthermore, the battery fixing frame is a rectangular frame, and infrared sensors and battery locking mechanisms are provided on opposite sides of the rectangular frame.

[0011] Furthermore, the de-icing circuit is connected to the vehicle's heating system via two valves, one of which is located at the inlet end of the de-icing circuit, and the other is located at the outlet end of the de-icing circuit.

[0012] Furthermore, the battery de-icing system also includes an ambient temperature sensor, which is connected to the vehicle body and is used to detect the ambient temperature outside the vehicle.

[0013] According to another aspect of the present invention, a vehicle is provided having a battery de-icing system, which is the battery de-icing system described above.

[0014] According to another aspect of the present invention, a battery swapping method for vehicles is provided. The battery swapping method is based on the aforementioned battery de-icing system and includes the following steps: acquiring vehicle ambient temperature information and battery mounting frame status information, wherein the battery mounting frame status information is at least used to characterize whether the battery locking mechanism has frozen; when it is determined that the vehicle ambient temperature information is within a preset temperature range and the battery locking mechanism has frozen, generating a control instruction set, the control instruction set being used to control the vehicle heating system to start heating and open valves to transfer heated liquid to the de-icing circuit.

[0015] Furthermore, the battery fixing frame status information is obtained by infrared sensors installed on the battery fixing frame. At least one battery locking mechanism is provided between two adjacent infrared sensors. When a foreign object is detected between two adjacent infrared sensors, it is determined that the battery locking mechanism has frozen.

[0016] By applying the technical solution of this invention, an ice-removing circuit is set in the annular heating cavity to remove ice condensed on the battery locking mechanism in a timely manner, ensuring smooth battery swapping. The heat energy of the vehicle's heating system is used to remove ice and snow, saving the vehicle's energy while ensuring the battery swapping function is realized. This solves the technical problem in the prior art that the battery locking mechanism cannot be automatically de-iced when frozen, thus causing battery swapping to be unsuccessful, and effectively improves the user experience.

In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0038] like Figure 1 As shown, according to a specific embodiment of this application, a battery de-icing system is provided.

[0039] Specifically, the battery de-icing system includes a battery fixing frame 1 and a battery locking mechanism 3. The battery fixing frame 1 has an installation cavity, and an annular partition is provided inside the battery fixing frame 1 to divide the installation cavity into a battery installation cavity and an annular heating cavity. The battery installation cavity is used to install the power battery 2, and the power battery 2 is disposed with a gap between it and the annular partition. The battery locking mechanism 3 is connected to the annular partition and has a working state of locking the power battery 2 to the battery fixing frame 1 and a releasing state of releasing the power battery 2 from the battery fixing frame 1. A de-icing circuit 4 is provided inside the annular heating cavity. The de-icing circuit 4 is connected to the vehicle's whole vehicle heating system 5, and the heating liquid of the whole vehicle heating system 5 can flow in the de-icing circuit 4 to de-ic the battery fixing frame 1.

[0040] By applying the technical solution of this embodiment, by setting up a de-icing circuit 4 in the annular heating cavity, the ice condensed on the battery locking mechanism 3 is removed in a timely manner, ensuring smooth battery swapping. The heat energy of the vehicle heating system 5 is used to remove ice and snow, saving vehicle energy while ensuring the battery swapping function is realized. This solves the technical problem in the prior art that the battery locking mechanism cannot be automatically de-iced when frozen, thus causing battery swapping to be unsuccessful, and effectively improves the user experience.

[0041] To improve the de-icing effect, the de-icing circuit 4 should be set as close as possible to the annular partition so that heat can be quickly transferred to the battery locking mechanism 3 to achieve rapid de-icing.

[0042] In one exemplary embodiment of this application, the vehicle heating system 5 includes at least a heat-generating element (such as a PTC heater); the battery locking mechanism 3 cooperates with a locking engagement mechanism provided on the power battery 2 to achieve locking and releasing of the power battery 2, specifically, as shown in... Figure 1 As shown, the battery fixing frame 1 is equipped with four battery locking mechanisms 3, with two battery locking mechanisms 3 respectively installed on opposite sides of the power battery 2. Depending on actual needs, locking mechanisms can be added to different locations on the battery fixing frame 1 for battery locking, and the de-icing circuit 4 can also be used to de-ice the locking mechanisms at other locations.

[0043] In this embodiment, the battery locking mechanism 3 is arranged close to the periphery of the power battery 2; the annular heating cavity can be a hollow structure, that is, the annular heating cavity is an annular cavity formed by the annular partition and the frame of the battery fixing frame 1. The de-icing circuit 4 is a pipeline for circulating heating liquid. The de-icing circuit 4 is placed in the annular cavity. Optionally, the annular partition can be integrated with the battery fixing frame 1, or the annular partition and the battery fixing frame 1 can be detached to facilitate adjustment of the size of the battery mounting cavity. In an alternative embodiment of this application, the annular partition is omitted, and the cavity wall of the mounting cavity of the battery fixing frame 1 is set at a distance from the outer edge of the battery fixing frame 1, so that the mounting cavity directly serves as the battery mounting cavity. An annular channel is drilled between the cavity wall of the mounting cavity and the outer edge of the battery fixing frame 1. This annular channel can be used as an annular heating cavity. The de-icing circuit 4 is set in the annular channel (that is, the de-icing circuit 4 is buried in the battery fixing frame 1). Alternatively, the annular channel can be directly used as the de-icing circuit 4. To facilitate the flow control of the heating liquid, a guide pipe and a control valve can be set at the end of the annular channel.

[0044] In an alternative embodiment of this application, part of the vehicle heating system 5 may also be integrated with the battery mounting frame 1. For example, the heat-generating elements in the vehicle heating system 5 may be integrated with the battery mounting frame 1.

[0045] Furthermore, the battery de-icing system also includes an infrared sensor 6, which is connected to the annular separator. There are multiple infrared sensors 6, which are used to detect whether there are foreign objects between the annular separator and the power battery 2. The foreign objects include at least ice and mud.

[0046] It should be understood that the purpose of setting up the infrared sensor 6 is to detect whether there are foreign objects inside the battery fixing frame 1. Depending on the actual needs, the infrared sensor 6 can also be replaced with other detection devices that can achieve the same detection purpose. For example, an image acquisition device can be set up to detect the images inside the battery fixing frame 1 in real time, and determine whether there are foreign objects based on the obtained image results. Alternatively, a pressure sensor can be set up to detect foreign objects inside the battery fixing frame 1.

[0047] In one exemplary embodiment of this application, foreign objects include ice, mud, or other impurities. The detection of foreign objects is not limited to subsequent de-icing treatment; it can also be used for other fault diagnosis and treatment. For example, when foreign objects such as stones or mud are detected in the battery mounting frame 1, the vehicle issues a warning message to remind the user to clean or repair the battery mounting frame 1.

[0048] In one exemplary embodiment of this application, a detection device (i.e., the detection device is connected to the battery locking mechanism 3) can also be added to the battery locking mechanism 3 to detect whether the battery locking mechanism 3 has frozen. The detection device can also be equipped with more detection functions as needed. For example, the detection device can also be used to detect whether the battery locking mechanism 3 is locked in place, whether it has fallen off, whether the battery locking mechanism 3 is properly connected to the battery fixing frame 1, the temperature of the battery locking mechanism 3, etc., so as to detect vehicle abnormalities in a timely manner and extend the service life of the vehicle.

[0049] Optionally, there are multiple battery locking mechanisms 3, with at least one battery locking mechanism 3 provided between adjacent infrared sensors 6.

[0050] In this embodiment, by setting a battery locking mechanism 3 between adjacent infrared sensors 6, it is possible to determine whether the battery locking mechanism 3 has frozen or has other foreign objects based on the detection results of the two infrared sensors 6, resulting in more accurate detection results and avoiding detection errors that may be caused by the failure of one side of the infrared sensor 6.

[0051] Optionally, there are multiple battery locking mechanisms 3, and at least one infrared sensor 6 is provided between adjacent battery locking mechanisms 3.

[0052] In this embodiment, by providing at least one infrared sensor 6 between adjacent battery locking mechanisms 3, one infrared sensor 6 can be used to detect both battery locking mechanisms 3, thereby improving the utilization rate of the infrared sensor 6.

[0053] Furthermore, the battery fixing frame 1 is a rectangular frame, and infrared sensors 6 and battery locking mechanisms 3 are provided on opposite sides of the rectangular frame.

[0054] like Figure 1 As shown, in an exemplary embodiment of this application, the battery locking mechanism 3 is disposed on the first and third sides of the power battery 2. Correspondingly, the infrared sensor 6 is disposed on the first and third sides of the power battery 2, and a battery locking mechanism 3 is disposed between the two infrared sensors 6. The battery locking mechanism 3 is not disposed on the second and fourth sides of the power battery 2. The infrared sensor 6 located at the corner of the first and third sides of the power battery 2 can also detect whether there are foreign objects on the second and fourth sides of the power battery 2.

[0055] Furthermore, the de-icing circuit 4 is connected to the vehicle heating system 5 via valves 8. There are two valves 8, one of which is located at the liquid inlet of the de-icing circuit 4, and the other is located at the liquid outlet of the de-icing circuit 4.

[0056] By setting two valves 8, the inlet and outlet of the de-icing circuit 4 can be distinguished, facilitating the adjustment of the liquid flow rate in the de-icing circuit 4. For example, when rapid de-icing is required or the outside temperature is low, the opening of the valve at the inlet can be increased to allow the heating liquid to flow rapidly.

[0057] Furthermore, the battery de-icing system also includes an ambient temperature sensor 7, which is connected to the vehicle body and is used to detect the ambient temperature outside the vehicle. By detecting the ambient temperature outside the vehicle, it can be determined whether the vehicle is prone to icing, and thus whether battery de-icing is necessary.

[0058] According to another specific embodiment of this application, a vehicle is provided, which has a battery de-icing system, namely the battery de-icing system in the above embodiment. The vehicle in this embodiment can be a pure electric vehicle, a hybrid vehicle, or other new energy vehicle. By adopting the battery de-icing system in the above embodiment, the vehicle can perform intelligent detection before battery swapping, determine whether the battery locking mechanism 3 is covered by ice and snow and cannot swap batteries, and automatically remove the ice and snow to ensure the smooth progress of subsequent battery swapping. Furthermore, in this embodiment, the heat energy generated during vehicle operation is used to remove ice and snow, saving corresponding energy of the entire vehicle while ensuring the battery swapping function is realized. Corresponding monitoring and control are performed through the vehicle controller to improve the efficiency of each link and reduce losses.

[0059] According to another specific embodiment of this application, a battery swapping method for vehicles is provided, the battery swapping method being based on the aforementioned battery de-icing system, such as... Figure 2 As shown, the battery swapping method includes the following steps:

[0060] Step S21: Obtain vehicle ambient temperature information and battery fixing frame status information, wherein the battery fixing frame status information is used at least to characterize whether the battery locking mechanism 3 has frozen.

[0061] Specifically, in step S21, the vehicle control unit 9 acquires the vehicle ambient temperature information and the battery mounting frame status information. The battery mounting frame status information is obtained by a detection device installed on the battery mounting frame 1, and the vehicle ambient temperature information is obtained by an ambient temperature sensor 7 connected to the vehicle body. The vehicle control unit 9 connects to the detection device and the ambient temperature sensor 7 and transmits data. It should be understood that the data transmission methods include wired transmission and wireless transmission.

[0062] Step S22: When the vehicle ambient temperature is determined to be within the preset temperature range and the battery locking mechanism 3 is frozen, a control command set is generated. The control command set is used to control the vehicle heating system 5 to start heating and open the valve 8 to transfer the heated liquid to the de-icing circuit 4.

[0063] Optionally, in step S22, the control instruction set can also be used to issue a prompt message to the user to prompt the user to activate the battery swapping pre-de-icing function.

[0064] Through steps S21-S22, vehicle ambient temperature information and battery mounting frame status information are obtained. The battery mounting frame status information at least indicates whether the battery locking mechanism 3 has frozen. If the vehicle ambient temperature is within a preset temperature range and the battery locking mechanism 3 has frozen, a control command set is generated. This control command set is used to control the vehicle heating system 5 to start heating and open valve 8 to transfer heated liquid to the de-icing circuit 4. When the ambient temperature is low and the battery locking mechanism 3 is confirmed to be frozen, automatic de-icing can be performed, ensuring smooth subsequent battery swapping.

[0065] Optionally, the status information of the battery fixing frame 1 is obtained by the infrared sensor 6 installed on the battery fixing frame 1. At least one battery locking mechanism 3 is provided between two adjacent infrared sensors 6. When a foreign object is detected between two adjacent infrared sensors 6, it is determined that the battery locking mechanism 3 has frozen.

[0066] In this embodiment, when a foreign object is detected between two adjacent infrared sensors 6, it can be preliminarily determined that the battery locking mechanism 3 has frozen. If the vehicle's ambient temperature is within a preset temperature range, it can be confirmed that the battery locking mechanism 3 has frozen. The preset temperature range is a preset range of ambient temperatures prone to icing.

[0067] This application also provides a preferred embodiment of a battery de-icing system and a battery swapping method for vehicles, wherein the battery swapping method for vehicles is based on the battery de-icing system of this embodiment.

[0068] Specifically, such as Figure 1 As shown, the power battery 2 (battery swapping section) is the part of the battery that can be detached from the vehicle; the battery fixing frame 1 is the structure on the vehicle body that provides a fixation for the battery swapping section; the de-icing circuit 4 is a multi-loop channel integrated in the battery fixing frame 1. To prevent road debris from damaging the de-icing circuit 4 during driving, the de-icing circuit 4 is integrated inside the battery fixing frame 1; the battery locking mechanism 3 is a structure that fixes and locks the power battery 2 to the battery fixing frame 1; the infrared sensor 6 is used to detect whether there are foreign objects between two adjacent infrared sensors 6. The infrared sensor 6 can interact with the vehicle control unit 9 to inform it of the status of the gap between the power battery 2 and the battery fixing frame 1; the ambient temperature sensor 7 is used to detect the ambient temperature outside the vehicle.

[0069] like Figure 3 As shown, the battery swapping method applied to vehicles includes the following steps: The vehicle control unit 9 makes a comprehensive judgment based on the collected information (whether there are foreign objects between the infrared sensors 6 and the temperature value fed back by the ambient temperature sensor 7). When de-icing is required, the vehicle heating system 5 and the valve 8 set between the vehicle heating system 5 and the de-icing circuit 4 are automatically turned on to circulate heated liquid so that the ice and snow can melt. The heat of the vehicle heating system 5 can come from the vehicle's heat-generating components or heating elements to improve the working efficiency of the corresponding assemblies. When de-icing is not required, the valve 8 is turned off to reduce the dissipation of vehicle heating energy.

[0070] It should be noted that, in Figure 3 In this context, the cooling circuit valve is the aforementioned valve 8, the cooling circuit is the aforementioned de-icing circuit 4, the "ice and snow freezing locking mechanism temperature" and the "ice and snow easily occur temperature" are the same temperature range, namely the preset temperature range in the aforementioned step S22.

[0071] Using the battery de-icing system and battery swapping method described in the above embodiments, the vehicle control unit 9 intelligently controls the opening or closing of the de-icing circuit 4 based on the monitoring results of information from the ambient temperature sensor 7 and infrared sensor 6, thereby saving the vehicle's heating energy.

[0072] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0073] The above-described method embodiments can be executed in an electronic device or similar computing device that includes a memory and a processor in a vehicle. Taking an electronic device running in a vehicle as an example, such as... Figure 4 As shown, the vehicle's electronic devices may include one or more processors 102 (processors may include, but are not limited to, central processing units (CPUs), graphics processing units (GPUs), digital signal processing (DSP) chips, microprocessors (MCUs), programmable logic devices (FPGAs), neural network processors (NPUs), tensor processors (TPUs), artificial intelligence (AI) type processors, etc.) and a memory 104 for storing data. Optionally, the vehicle's electronic devices may also include a transmission device 106 for communication functions, an input / output device 108, and a display 110. Those skilled in the art will understand that... Figure 4 The structures shown are for illustrative purposes only and do not limit the structure of the electronic devices in the vehicle described above. For example, the electronic devices in a vehicle may include more or fewer components than those described above, or have a different configuration than those described above.

[0074] The memory 104 can be used to store computer programs, such as application software programs and modules, like the computer program corresponding to the battery swapping method in this embodiment of the invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, thereby realizing the aforementioned battery swapping method. The memory 104 may include high-speed random access memory, and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0075] The transmission device 106 is used to receive or send data via a network. Specific examples of the network described above may include a wireless network provided by the mobile terminal's communication provider. In one example, the transmission device 106 includes a Network Interface Controller (NIC), which can connect to other network devices via a base station to communicate with the Internet. In another example, the transmission device 106 may be a Radio Frequency (RF) module used for wireless communication with the Internet.

[0076] Display 110 may be, for example, a touchscreen liquid crystal display (LCD). This LCD allows a user to interact with the user interface of the mobile terminal. In some embodiments, the mobile terminal has a graphical user interface (GUI), which allows the user to interact with the GUI via finger contact and / or gestures on a touch-sensitive surface. The human-computer interaction functions may optionally include: creating web pages, drawing, word processing, creating electronic documents, playing games, video conferencing, instant messaging, sending and receiving emails, a call interface, playing digital video, playing digital music, and / or web browsing, etc. Executable instructions for performing the above-mentioned human-computer interaction functions are configured / stored in one or more processor-executable computer program products or readable storage media.

[0077] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention, in essence, or the part that contributes to the prior art, can be embodied in the form of a software product. This computer software product is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk) and includes several instructions to cause a terminal device (which may be a mobile phone, computer, server, or network device, etc.) to execute the methods described in the various embodiments of the present invention.

[0078] This embodiment also provides a battery swapping device for vehicles, which is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0079] Figure 5 This is a structural block diagram of a battery swapping device applied to a vehicle according to one embodiment of the present invention, such as... Figure 5 As shown, the device includes: an acquisition module 51, which is used to acquire vehicle ambient temperature information and battery fixing frame status information, wherein the battery fixing frame status information is used to at least characterize whether the battery locking mechanism 3 has frozen; and a generation module 52, which is used to generate a control command set when it is determined that the vehicle ambient temperature information is within a preset temperature range and the battery locking mechanism 3 has frozen, wherein the control command set is used to control the vehicle heating system 5 to start heating and open the valve 8 to transfer heated liquid to the de-icing circuit 4.

[0080] The aforementioned device allows the acquisition module 51 to acquire vehicle ambient temperature information and battery mounting frame status information. The battery mounting frame status information at least indicates whether the battery locking mechanism 3 has frozen. The generation module 52, upon determining that the vehicle ambient temperature is within a preset temperature range and that the battery locking mechanism 3 has frozen, generates a control command set. This control command set controls the vehicle heating system 5 to start heating and opens valve 8 to transfer heated liquid to the de-icing circuit 4. When the ambient temperature is low and it is determined that the battery locking mechanism 3 has frozen, automatic de-icing can be performed, ensuring smooth subsequent battery swapping.

[0081] It should be noted that the above modules can be implemented by software or hardware. For the latter, they can be implemented in the following ways, but are not limited to: all the above modules are located in the same processor; or, the above modules are located in different processors in any combination.

[0082] Embodiments of the present invention also provide a storage medium storing a computer program, wherein the computer program is configured to execute the steps in any of the above method embodiments when running.

[0083] Optionally, in this embodiment, the storage medium may be configured to store a computer program for performing the following steps:

[0084] Step S1: Obtain vehicle ambient temperature information and battery fixing frame status information, wherein the battery fixing frame status information is used at least to characterize whether the battery locking mechanism 3 has frozen.

[0085] Step S2: When the vehicle ambient temperature is determined to be within the preset temperature range and the battery locking mechanism 3 is frozen, a control command set is generated. The control command set is used to control the vehicle heating system 5 to start heating and open the valve 8 to transfer the heated liquid to the de-icing circuit 4.

[0086] Optionally, in this embodiment, the storage medium may include, but is not limited to, various media capable of storing computer programs, such as USB flash drives, read-only memory (ROM), random access memory (RAM), portable hard drives, magnetic disks, or optical disks.

[0087] Embodiments of the present invention also provide a processor configured to run a computer program to perform the steps in any of the above method embodiments.
