[0041] When all power sources of the vehicle are turned off and the engine is turned off, the electronic control components and anti-theft system on the vehicle are still working and consume a certain amount of electricity. At this time, the battery is also continuously discharging. The capacity of the battery is affected by the temperature. If the vehicle is parked for a long time, the battery is easily depleted, causing the vehicle to be unable to start. Therefore, by prompting the driver of the battery power status after the vehicle is turned off, deep discharge of the battery can be avoided, the battery life can be extended, and the number of times the vehicle breaks down due to battery reasons can be reduced. In the prior art, the battery management method is: after detecting that the battery power is low, the high-voltage system is started to charge the battery through the power battery. However, in the prior art, fuel vehicles are not equipped with power batteries, and the battery management scheme of the prior art is not suitable for traditional fuel vehicles, resulting in reduced applicability of the battery management scheme.

[0042] In order to solve the above technical problems, the embodiments of the present application propose the following technical concepts: the inventor considers using an intelligent battery sensor to collect battery parameter data of a battery, judging whether the battery parameter data is valid according to the validity flag information in the battery parameter data, obtaining a validity judgment result, selecting target remaining power information from the first remaining power information and the second remaining power information according to the judgment result, determining whether the battery is faulty according to the fault parameter information in the battery parameter data, and generating an alarm message if the target remaining power information is less than a preset threshold and the battery is not faulty, by sending the alarm message to an additional controller, the additional controller sends the alarm message to the Internet of Vehicles platform, and the Internet of Vehicles platform sends the alarm message to the user terminal, prompting the user that the battery is low on power. The following is a detailed description using a detailed embodiment.

[0043] Figure 1 A schematic diagram of a scenario of a method for controlling a battery of a vehicle provided in an embodiment of the present application, such as Figure 1 As shown, the application scenario includes a smart battery sensor 101, a vehicle controller 102, an additional controller 103, a vehicle networking platform 104 and a user terminal 105.

[0044] Specifically, the vehicle controller 102 receives the battery parameter data sent by the intelligent battery sensor 101, determines whether the battery parameter data is valid according to the validity flag information in the battery parameter data, and obtains a determination result. The vehicle controller 102 selects the target remaining power information from the first remaining power information and the second remaining power information according to the determination result, and determines whether the battery has a fault according to the fault parameter information. If the target remaining power information is less than a preset threshold and the battery has no fault, an alarm message is generated, and the vehicle controller 102 sends the alarm message to the additional controller 103. The additional controller 103 sends the alarm message to the Internet of Vehicles platform 104. The vehicle network platform 104 sends the alarm message to the user terminal 105 to prompt the user that the battery is low on power.

[0045] Figure 2 This is a flow chart of a method for controlling a battery of a vehicle provided in an embodiment of the present application. The execution subject of this embodiment may be a vehicle controller, and this embodiment is not particularly limited here. Figure 2 As shown, the method includes:

[0046] S201: Receive battery parameter data sent by an intelligent battery sensor, wherein the battery parameter data includes validity mark information, first remaining power information and fault parameter information of the battery.

[0047] In this embodiment, the first remaining power information is the SOC (State of Charge) value of the battery collected by the intelligent battery sensor.

[0048] In this embodiment, the battery parameter data acquired by the intelligent battery sensor IBS (Inteligent Battery Sensor, referred to as IBS) includes but is not limited to measuring the charging or discharging current flowing through the battery, the voltage between the battery terminals, and the battery temperature. In this embodiment, the battery parameter data acquired by the intelligent battery sensor is returned to the intelligent battery sensor in the form of a data packet via the LIN bus.

[0049] S202: Determine whether the battery parameter data is valid according to the validity flag information, and obtain a validity determination result.

[0050] In this embodiment, the validity flag information is a battery self-calibration flag.

[0051] Specifically, if the battery self-calibration flag is equal to 1, the battery parameter data is valid; if the battery self-calibration flag is equal to 0, the battery parameter data is invalid.

[0052] S203: According to the validity determination result, target remaining power information is selected from the first remaining power information and the second remaining power information, wherein the second remaining power information is calculated for the battery and received from the additional controller.

[0053] Specifically, if the determination result is that the battery parameter data is valid, the first remaining power information is recorded as the target remaining power information.

[0054] Specifically, if the determination result is that the battery parameter data is invalid, the additional controller calculates and generates the second remaining power information, compares the first remaining power information and the second remaining power information, and takes the minimum value and records it as the target remaining power information.

[0055] S204: Determine whether the battery has a fault based on the fault parameter information.

[0056] In this embodiment, the fault parameter information includes but is not limited to the internal fault variable of the smart battery sensor, the LIN transmission fault variable and the battery fault variable.

[0057] Specifically, if all fault variables in the fault parameter information are 0, it is determined that the battery has no fault; if at least one fault variable in the fault parameter information is 1, it is determined that the battery has a fault.

[0058] S205: If the target remaining power information is less than a preset threshold and the battery has no faults, an alarm message is generated.

[0059] Specifically, if the target remaining power information is less than a preset SOC threshold, a high-power consumption flag is obtained and an alarm message is generated.

[0060] S206: Sending an alarm message to the additional controller, so that the additional controller sends the alarm message to the Internet of Vehicles platform, so that the Internet of Vehicles platform sends the alarm message to the user terminal to remind the user that the battery is low on power.

[0061] In this embodiment, the vehicle network platform sends warning information to the user terminal in the form of, but not limited to, text messages, phone calls, and in-application notifications.

[0062] It can be seen from the above embodiments that the battery parameter data of the battery is obtained through the intelligent battery sensor, and whether the battery parameter data is valid is determined according to the validity flag information in the battery parameter data, and a judgment result is generated. According to the judgment result, the target remaining power information is selected from the first remaining power information and the second remaining power information, and whether the battery is faulty is determined according to the fault parameter information. If the battery is not faulty and the target remaining power information is less than a preset threshold, an alarm message is generated and sent to the additional controller. The additional controller sends the alarm message to the Internet of Vehicles platform, and the Internet of Vehicles platform sends an alarm message to the user terminal to remind the user that the battery is low on power, which solves the problem of battery management of fuel vehicles in the prior art, does not require a power battery, and improves the applicability of battery management.

[0063] In one embodiment of the present application, step S203 includes:

[0064] S2031: If the determination result is that the battery parameter data is valid, the first remaining power information is recorded as the target remaining power information.

[0065] In this embodiment, the first remaining power information is the SOC value of the battery acquired by the intelligent battery sensor.

[0066] S2032: If the determination result is that the battery parameter data is invalid, obtain the second remaining power information calculated and generated by the additional controller for the battery.

[0067] In this embodiment, the additional controller calculates and generates a formula for the second remaining power information for the battery as follows:

[0068]

[0069]

[0070] In the formula, Indicates the remaining power information stored in EEPROM after power off; Indicates the battery current; Indicates the power-off time of the attached controller; Indicates the rated capacity of the battery; Indicates the initial remaining power information when the additional controller is powered on; Indicates the second remaining power information calculated and generated by the additional controller.

[0071] S2033: Compare the second remaining power information with the first remaining power information, select the power information with the smallest value between the first remaining power information and the second remaining power information, and record it as the target remaining power information.

[0072] Specifically, the numerical values ​​of the first remaining power information and the second remaining power information are compared, and the minimum value between the two is taken and recorded as the target remaining power information.

[0073] It can be seen from the above embodiments that if the battery parameter data is invalid, the second remaining power information is calculated for the battery through an additional controller, the numerical values ​​of the first remaining power information and the second remaining power information are compared, the minimum value is recorded as the target remaining power information, and the SOC is calculated by the ampere-hour integration method after the intelligent battery sensor fails, and the low-power judgment is made based on the calculated SOC value to avoid false low-power alarms from the system; if the battery parameter data is valid, the SOC in the battery parameter data is directly used to make a low-power judgment, which improves the speed of judgment.

[0074] In one embodiment of the present application, after step S201, the following steps are further included:

[0075] S301: Obtain discharge current from battery parameter data.

[0076] In this embodiment, the unit of the discharge current is ampere or milliampere.

[0077] S302: Determine whether the discharge current is smaller than a preset current value.

[0078] Specifically, it is compared whether the numerical value of the discharge current exceeds the preset current value, or whether the unit of the collected current value exceeds the unit of the preset current value.

[0079] S303: If the discharge current is smaller than the preset current value, abnormal power usage mark information in the battery parameter data is obtained.

[0080] In this embodiment, the content recorded in the abnormal power usage mark information includes but is not limited to the abnormal current value of the abnormal power usage, the component information causing the abnormality, and the abnormality log.

[0081] S304: Send abnormal power usage mark information to the additional controller, so that the additional controller sends the abnormal power usage mark information to the Internet of Vehicles platform, so that the Internet of Vehicles platform generates prompt information according to the abnormal power usage mark information, and sends the prompt information to the user terminal.

[0082] In this embodiment, the form of sending the prompt information includes but is not limited to text messages, phone calls, and notifications within the application.

[0083] From the above embodiments, it can be seen that by monitoring the discharge current in the battery parameter data, determining the size of the discharge current to obtain abnormal power usage sign information, and sending prompt information to the user terminal, the impact of irregular power usage on battery life can be avoided.

[0084] In one embodiment of the present application, before step S201, the method further includes:

[0085] S401: When the vehicle is powered off, a preset wake-up time interval is sent to the additional controller, so that the additional controller reads the LIN data and remaining power information obtained by the intelligent battery sensor according to the preset wake-up time interval.

[0086] In this embodiment, when the whole vehicle is powered off or the additional controller is powered off, the remaining battery power information of the battery will be stored in an EEPROM (Electrically Erasable Programmable read only memory).

[0087] S402: Receive LIN data and remaining power information sent by the additional controller, and determine whether the battery is low on power based on the LIN data and the remaining power information.

[0088] Specifically, after the additional controller is powered on, the LIN data sent by the intelligent battery sensor and the data in the EEPROM are read to obtain the remaining power information.

[0089] S403: If the battery is in a low-power state, an alarm message is generated and sent to a user terminal to remind the user that the battery is low-power.

[0090] In this embodiment, the forms of sending the alarm information to the user terminal include but are not limited to text messages, phone calls, and notifications within applications.

[0091] It can be seen from the above embodiments that the additional controller is woken up regularly to obtain data from the intelligent battery sensor to determine whether the battery is low on power, thereby avoiding power loss caused by long-term parking after the vehicle is powered off and turned off.
