Description

Technical Field

[0001] The present invention belongs to the field of automobile technology, and in particular relates to an intelligent control method and system for dual low-voltage batteries of a whole vehicle. Background Art

[0002] With the development of society, the popularity of automobiles is getting higher and higher, and batteries, as an indispensable part of automobiles, have received widespread attention from researchers.

[0003] Among them, the battery is the power supply for the vehicle's low-voltage electrical appliances and ignition system. After the vehicle is started, the generator will automatically charge the battery. For modified vehicles such as real estate, ambulances, etc., if the user uses the in-vehicle electrical appliances for a long time when the vehicle is not started, for example, using the in-vehicle entertainment system IVI to play songs or medical equipment, it may cause the battery to over-discharge or even lose power, so that the battery does not have enough power to support the next start of the vehicle. When this condition occurs, the vehicle can only be started by jumping the battery, which will cause great trouble to the user.

[0004] In addition, some equipment of the modified vehicle requires battery power to work. If the starting battery is used to power these equipment, the battery may be frequently over-discharged, shortening the battery life. Moreover, when the battery is powering these loads, the user may fail to start the vehicle due to insufficient battery output power. Summary of the invention

[0026] When it is determined that the remaining power is lower than a threshold, a prompt message is issued, and the prompt message is used to remind the user to charge the vehicle in time.

[0027] Furthermore, in the step of controlling the bistable magnetic latching relay to be energized so that the modified battery circuit and the starting battery circuit are connected, the modified equipment in the vehicle is only electrically connected to the modified battery, and the starting battery and the modified battery are connected through the dual low-voltage battery relay to form a series circuit.

[0046] Embodiment 1

[0047] See also Figure 1 and Figure 2 , Figure 1 The figure shows a flow chart of an implementation method of a vehicle dual low-voltage battery intelligent control method provided by the first embodiment of the present invention. Figure 2 A block diagram of the device structure for realizing the intelligent control method of dual low-voltage batteries of a whole vehicle provided by the first embodiment of the present invention is shown, which is applied to the power supply system of the vehicle, and the power supply system includes a modified battery circuit, a starting battery circuit, and a bistable magnetic latching relay for controlling the on and off of the modified battery circuit and the starting battery circuit. The method specifically includes steps S10 to S13.

[0048] Step S10, obtaining a vehicle instruction and determining whether the vehicle instruction is a vehicle power-on instruction, if so, executing step S11.

[0049] It should be noted that the battery will only start working when the entire vehicle is powered on, that is, supply power to the equipment on the vehicle.

[0050] In step S11, the bistable magnetic latching relay is controlled to be closed to connect the modified battery circuit and the starting battery circuit.

[0051] Specifically, the vehicle includes a starting battery and a modified battery. It can be understood that the starting battery is an original battery, the modified battery is an additionally installed battery, and the starting battery and the modified battery each form a circuit in the vehicle, wherein the modified equipment in the vehicle is only electrically connected to the modified battery, and the starting battery and the modified battery are connected through a dual low-voltage battery relay to form a series circuit. When the bistable magnetic latching relay is controlled to be energized, the modified battery circuit and the starting battery circuit are connected, so that the modified battery can charge the starting battery.

[0052] In this embodiment, the bistable magnetic latching relay includes a high drive circuit and a low drive circuit, wherein the vehicle drive resource information is obtained to determine whether the vehicle drive resource information meets the preset requirements; if so, the bistable magnetic latching relay is controlled to be closed or disconnected through the high drive circuit; if not, the bistable magnetic latching relay is controlled to be closed or disconnected through the low drive circuit, specifically, as Figure 2As shown in , if high drive is selected according to the vehicle's own driving resources, the relay is disconnected through PIN1 and the bistable magnetic latching relay is closed through PIN4; if low drive is selected according to the vehicle's own driving resources, the relay is closed through PIN2 and the relay is disconnected through PIN3.

[0053] It should be noted that in order to extend the battery life, when the vehicle is powered on but not started, the bistable magnetic latching relay is controlled to be disconnected to stop the modified battery from charging the starting battery. Specifically, the vehicle command within the preset time is obtained, and it is determined whether the vehicle command is a vehicle start command. If not, the bistable magnetic latching relay is controlled to be disconnected. In this embodiment, the preset time is 60s, that is, when the vehicle is powered on for 60s and the vehicle start command is not received, the bistable magnetic latching relay is controlled to be disconnected.

[0054] Step S12, obtaining the remaining power of the starting battery sensed by the battery sensor, and determining whether the remaining power is lower than a threshold value, if not, executing step S13.

[0055] Specifically, the original vehicle battery, i.e. the starting battery, is equipped with a sensor for monitoring the battery status. As a slave node, it communicates with the master node body control module through the LIN bus. When the entire vehicle network enters a dormant state, the battery sensor will automatically wake up the body control module and then wake up the entire vehicle network according to the real-time status of the battery (such as low battery, abnormal discharge, etc.). The threshold value can be flexibly adjusted through calibration according to different needs.

[0056] In this embodiment, when it is determined that the remaining power is lower than the threshold, the vehicle's 4G networking module can wirelessly send a prompt message to the cloud platform and push it to the user's mobile phone APP, suggesting manual start of battery charging.

[0057] Step S13, controlling the bistable magnetic latching relay to be disconnected.

[0058] It should be noted that the interval time between the bistable magnetic latching relay being closed and disconnected is greater than the preset time. In the present embodiment, the preset time is 1000ms. The purpose is to prevent frequent switching in a short period of time from causing damage to the relay. In addition, the time of disconnection of the bistable magnetic latching relay is obtained, and it is determined whether the time is greater than the preset time, that is, whether it is greater than 1000ms. If so, the control signal stops being output. It can be understood that after the control relay executes the disconnection action, the control PIN pin output can be interrupted while maintaining the control PIN pin electrical signal output for more than 1000ms to prevent the relay control signal from being output continuously after power-off.

[0059] In summary, the present invention proposes an intelligent control method for a whole vehicle dual low-voltage battery, which obtains vehicle instructions and determines whether the vehicle instructions are vehicle power-on instructions; if so, controls the bistable magnetic latching relay to be energized to connect the modified battery circuit and the starting battery circuit; obtains the remaining power of the starting battery sensed by the battery sensor, and determines whether the remaining power is lower than a threshold value; if not, controls the bistable magnetic latching relay to be disconnected. Specifically, an additional battery is added to power the modified equipment, and the two power supply circuits are connected by a dual low-voltage battery relay. The relay is controlled to be disconnected or connected according to the vehicle's operating status, thereby avoiding damage to the starting battery caused by the modified equipment and realizing timely charging of the feeding battery, effectively solving the problem of the vehicle being unable to start due to power feeding of the modified vehicle battery equipment.
