Problems solved by technology

[0004] First, the abnormality of the battery has already occurred, but the detection period has not yet arrived, and the abnormality must wait until the next detection, and the detection mechanism is not real-time enough;
[0005] Second, the system function is not abnormal, the master node unit still needs to periodically wake up the battery sensor to confirm the information, which brings unnecessary power consumption

Embodiment 1

[0043] Embodiment 1 of the present invention proposes a vehicle-mounted storage battery monitoring method, figure 1 For the flowchart of the method described in embodiment one, refer to figure 1 , the method described in embodiment one comprises the steps:

[0044] Step S1, the sensing unit detects the status information of the storage battery in real time, and judges whether the storage battery is abnormal according to the status information. When it is determined that the storage battery is abnormal, the sensing unit generates a wake-up signal and sends the wake-up signal to the master node unit;

[0045] Step S2, after receiving the wake-up signal, the master node unit acquires the battery abnormality determination result of the sensing unit, and controls the alarm unit to issue an alarm according to the battery abnormality determination result.

[0046]Specifically, the sensing unit may include several battery sensors, several battery sensors are used as slave nodes of th...

Embodiment 2

[0064] Embodiment 2 of the present invention proposes a vehicle battery monitoring system, figure 2 For the frame diagram of the on-board battery monitoring system described in this embodiment, refer to figure 2 , the system described in this embodiment includes:

[0065] The sensing unit 1 is used to detect the status information of the storage battery in real time, and determine whether the storage battery is abnormal according to the status information. When it is determined that the storage battery is abnormal, the sensing unit 1 generates a wake-up signal and sends the wake-up signal to the master node unit 2; and

[0066] The master node unit 2 is configured to receive a wake-up signal from the sensing unit 1, obtain the battery abnormality determination result of the sensing unit 1 after receiving the wake-up signal, and control the alarm unit to issue an alarm according to the battery abnormality determination result.

[0067] In a specific embodiment, the sensing u...

Embodiment 3

[0078] Embodiment 3 of the present invention provides a vehicle, including the on-board battery monitoring system described in Embodiment 2.

Abstract

The invention relates to a vehicle-mounted storage battery monitoring method and system, a vehicle and a storage medium, and the method comprises the steps: S1, a sensing unit detects the state information of a storage battery in real time, judges whether the storage battery is abnormal or not according to the state information, and generates a wake-up signal and transmits the wake-up signal to a main node unit when the storage battery is judged to be abnormal; and S2, after the main node unit receives the wake-up signal, obtaining a storage battery abnormity judgment result of the sensing unit, and controlling an alarm unit to give an alarm according to the storage battery abnormity judgment result. According to the invention, periodic awakening of the main node unit can be avoided, the main node unit is awakened only under the abnormal condition, so that the power consumption is effectively reduced, and the timeliness of reporting the abnormal information is ensured.

Description

technical field [0001] The invention relates to the technical field of on-vehicle storage batteries, in particular to a monitoring method for an on-vehicle storage battery, a system thereof, a vehicle, and a storage medium. Background technique [0002] At present, the on-board battery monitoring method of the vehicle periodically wakes up the LIN network by the main node unit, reads the information of the battery sensor, and confirms whether there is any abnormality. [0003] In the process of realizing the present invention, the inventor found that there are two defects in the existing vehicle battery monitoring method: [0004] First, the abnormality of the battery has already occurred, but the detection period has not yet arrived, and the abnormality must wait until the next detection, and the detection mechanism is not real-time enough; [0005] Second, the system function is not abnormal, and the master node unit still needs to periodically wake up the battery sensor ...
