[0039] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0041] Since parking equipment such as parking air conditioners can still be in working condition after the vehicle is turned off, the power of the vehicle battery will decrease, which may easily cause the vehicle battery to lose power and damage the vehicle battery. Therefore, it is necessary to detect parameters such as the voltage of the vehicle battery in real time to monitor the performance of the vehicle battery to prevent the vehicle battery from being exhausted and reducing the service life of the vehicle battery.

[0042] Therefore, in order to accurately and reliably obtain the voltage of the vehicle battery, the present invention provides the following technical solutions:

[0043] See attached Figure 1 , Figure 1 1 is a flow chart of main steps of a vehicle battery monitoring method according to an embodiment of the present invention. Figure 2 FIG. 1 is a main structural block diagram of a vehicle battery monitoring system according to an embodiment of the present invention. Figure 2 As shown, the vehicle battery monitoring system of this embodiment may include a parking device controller 21, a first voltage detection device 22, a second voltage detection device 23 and a vehicle communication device 24. The vehicle battery 1 is connected to the parking device controller 21 through the first voltage detection device 22; the vehicle battery 1 is connected to the vehicle communication device 24 through the second voltage detection device 23; the parking device controller 21 is connected to the vehicle communication device 24. When the parking device is a parking air conditioner, the parking device controller 21 may be an internal control panel of the parking air conditioner. The vehicle communication device 24 may perform data communication based on the CAN bus.

[0044] In a specific implementation process, the controller 21 of the parking device is used to execute the following vehicle battery monitoring method:

[0045] like Figure 1 As shown, the vehicle battery monitoring method in the embodiment of the present invention mainly includes the following steps 101 to 103.

[0046] Step 101, detect whether the vehicle communication device 24 fails; if so, execute step 103; if not, execute step 102;

[0047] In a specific implementation process, the parking device controller 21 can communicate with the vehicle communication device 24 in real time, and can detect whether the vehicle communication device 24 fails based on whether the parking device controller 21 receives the communication signal of the vehicle communication device 24.

[0048] Specifically, if the controller 21 of the parking device does not receive the communication signal of the vehicle communication device 24 within the preset time, it can be determined that the vehicle communication device 24 has failed and step 103 is executed. Otherwise, it can be determined that the vehicle communication device 24 has not failed and step 102 is executed.

[0049] Step 102, obtaining the first voltage of the vehicle battery 1 detected by the second voltage detection device 23 from the vehicle communication device 24 as the actual voltage of the vehicle battery 1;

[0050] In a specific implementation process, if the vehicle communication device 24 does not fail, the first voltage of the vehicle battery 1 detected by the second voltage detection device 23 can be obtained from the vehicle communication device 24 as the actual voltage of the vehicle battery 1 .

[0051] In a specific implementation process, the second voltage detection device 23 may be a voltage sensor, and the first voltage of the vehicle battery 1 detected by the second voltage detection device 23 is relatively less affected by factors such as line loss and environment, and is relatively close to the actual voltage of the vehicle battery 1. When the second voltage detection device 23 sends the first voltage of the vehicle battery 1 to the vehicle controller via the vehicle communication device 24, the controller 21 of the parking device may also obtain the first voltage of the vehicle battery 1 from the vehicle communication device 24, and may directly use it as the actual voltage of the vehicle battery 1.

[0052] Step 103 : Acquire the second voltage of the vehicle battery 1 detected by the first voltage detection device 22 , and determine the actual voltage of the vehicle battery 1 according to the second voltage of the vehicle battery 1 .

[0053] In a specific implementation process, although the first voltage of the vehicle battery 1 detected by the second voltage detection device 23 can be obtained from the vehicle communication device 24 as the actual voltage of the vehicle battery 1, the vehicle communication device 24 may fail, and the first voltage of the vehicle battery 1 detected by the second voltage detection device 23 cannot be sent to the vehicle communication device 24. At this time, the controller 21 of the parking device cannot obtain the actual voltage of the vehicle battery 1. Therefore, in this embodiment, when the vehicle communication device 24 fails, the second voltage of the vehicle battery 1 detected by the first voltage detection device 22 can be directly obtained, and the actual voltage of the vehicle battery 1 can be determined based on the second voltage of the vehicle battery 1, thereby realizing the redundancy of the voltage detection circuit of the vehicle battery and improving the reliability of detecting the voltage of the vehicle battery.

[0054] Specifically, the first voltage detection device 22 may be a resistor. Since the connection line between the controller 21 of the parking device, the first voltage detection device 22 and the vehicle battery 1 does not need to be connected by a communication signal line, the second voltage of the vehicle battery 1 obtained by the first voltage detection device is greatly affected by line loss, environment, etc., and the detection accuracy is relatively low. Therefore, after obtaining the second voltage of the vehicle battery 1, the second voltage of the vehicle battery 1 may be compensated according to a preset compensation function to obtain the actual voltage of the vehicle battery 1. The corresponding parameters of the compensation function may include line loss, temperature, humidity, constants, etc.

[0055] The vehicle battery monitoring method of this embodiment sets two voltage detection loops. When it is detected that the vehicle communication device 24 is not faulty, the first voltage of the vehicle battery 1 detected by the second voltage detection device 23 is obtained from the vehicle communication device 24 as the actual voltage of the vehicle battery 1 to ensure the detection accuracy of the actual voltage of the vehicle battery 1; when it is detected that the vehicle communication device 24 is faulty, the second voltage of the vehicle battery 1 detected by the first voltage detection device 22 is obtained, and the actual voltage of the vehicle battery 1 is determined based on the second voltage of the vehicle battery 1, ensuring that the actual voltage of the vehicle battery 1 can still be obtained when the vehicle communication device 24 is faulty. In this way, the reliability of detecting the actual voltage of the vehicle battery 1 is improved.

[0056] In a specific implementation process, when the vehicle communication device 24 does not fail, within a preset time period, while obtaining the first voltage of the vehicle battery 1 detected by the second voltage detection device 23 from the vehicle communication device 24, the second voltage of the vehicle battery 1 detected by the first voltage detection device 22 can also be obtained. However, only the first voltage of the vehicle battery 1 is used as the actual voltage of the vehicle battery 1.

[0057] The difference between the first voltage of the vehicle battery 1 and the second voltage of the vehicle battery 1 can be used as the error between the first voltage of the vehicle battery 1 and the second voltage of the vehicle battery 1, and then the parameters corresponding to the preset compensation function are corrected according to the error between the first voltage of the vehicle battery 1 and the second voltage of the vehicle battery 1, so that when the vehicle communication device 24 fails subsequently, the actual voltage of the vehicle battery 1 can be obtained using the corrected compensation function with relatively high accuracy.

[0058] Specifically, the constant in the preset function may be adjusted according to a certain correction coefficient according to the error between the first voltage of the vehicle battery 1 and the second voltage of the vehicle battery 1 , so that the actual voltage of the vehicle battery 1 with relatively high accuracy can be obtained.

[0059] In a specific implementation process, if the actual voltage of the vehicle battery 1 is less than a preset voltage, the vehicle battery 1 can be controlled to stop supplying power to the parking device, thereby preventing the vehicle battery 1 from running low on power.

[0060] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present invention.

[0061] Furthermore, the present invention also provides a monitoring device for a vehicle battery.

[0062] See attached Figure 3 , Figure 3 FIG. 1 is a main structural block diagram of a vehicle battery monitoring device according to an embodiment of the present invention. Figure 3 As shown, the vehicle battery monitoring device in the embodiment of the present invention may include Figure 2 The controller 21 of the parking device in the vehicle monitoring system may include a detection module 31 and a monitoring module 32.

[0063] A detection module 31 is used to detect whether the vehicle communication device 24 fails;

[0064] The monitoring module 32 is used to obtain the first voltage of the vehicle battery 1 detected by the second voltage detection device 23 from the vehicle communication device 24 as the actual voltage of the vehicle battery 1 if the vehicle communication device 24 is not faulty; and to obtain the second voltage of the vehicle battery 1 detected by the first voltage detection device 22 if the vehicle communication device 24 is faulty, and determine the actual voltage of the vehicle battery 1 based on the second voltage of the vehicle battery 1.

[0065] When determining the actual voltage of the vehicle battery 1 according to the second voltage of the vehicle battery 1 , the monitoring module 32 may compensate the second voltage of the vehicle battery 1 according to a preset compensation function to obtain the actual voltage of the vehicle battery 1 .

[0066] The vehicle battery monitoring device of this embodiment sets two voltage detection loops. When it is detected that the vehicle communication device 24 is not faulty, the first voltage of the vehicle battery 1 detected by the second voltage detection device 23 is obtained from the vehicle communication device 24 as the actual voltage of the vehicle battery 1 to ensure the detection accuracy of the actual voltage of the vehicle battery 1; when it is detected that the vehicle communication device 24 is faulty, the second voltage of the vehicle battery 1 detected by the first voltage detection device 22 is obtained, and the actual voltage of the vehicle battery 1 is determined based on the second voltage of the vehicle battery 1, ensuring that the actual voltage of the vehicle battery 1 can still be obtained when the vehicle communication device 24 fails. In this way, the reliability of detecting the actual voltage of the vehicle battery 1 is improved.

[0067] In a specific implementation process, the monitoring module 32 is further used to:

[0068] If the vehicle communication device 24 does not fail, the first voltage of the vehicle battery 1 and the second voltage of the vehicle battery 1 are continuously obtained within a preset time period;

[0069] determining an error between a first voltage of the vehicle battery 1 and a second voltage of the vehicle battery 1;

[0070] According to the error, the parameters corresponding to the preset compensation function are corrected.

[0071] In a specific implementation process, the monitoring module 32 is further used to:

[0072] If the actual voltage of the vehicle battery 1 is less than the preset voltage, the vehicle battery 1 is controlled to stop supplying power to the parking device.
