Embodiment 1

[0043] Embodiment 1 of the present invention proposes a vehicle 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 power and discharge current of the battery in real time, and judges whether the battery is abnormal according to the power and discharge current of the battery. When it is determined that the battery is abnormal, the sensing unit generates a wake-up signal and sends the wake-up signal to master node unit;

[0045] Step S2, the master node unit reads the abnormal judgment result of the sensing unit according to the wake-up signal, and drives the self-holding relay to disconnect according to the abnormal judgment result; wherein, the controlled load and the storage battery are electrically connected through the self-holding relay. connect.

[0046]Specifically, in this embodiment, the sensing ...

Embodiment 2

[0068] Embodiment 2 of the present invention proposes a vehicle battery 3 monitoring system, see image 3 , the system described in Embodiment 2 includes:

[0069] The sensing unit 1 is used to detect the electric quantity and discharge current of the storage battery 3 in real time, and judge whether the storage battery 3 is abnormal according to the electric quantity and discharge current of the storage battery 3. When it is determined that the storage battery 3 is abnormal, the sensing unit 1 generates a wake-up signal and The wake-up signal is sent to the master node unit 2; and

[0070] The master node unit 2 is used to read the abnormal judgment result of the sensing unit 1 according to the wake-up signal, and drive the self-holding relay 4 to disconnect according to the abnormal judgment result; wherein, the controlled load 5 and the storage battery 3 pass through the The self-holding relay 4 is electrically connected.

[0071] In a specific embodiment, the master node...

Abstract

The invention relates to a vehicle storage battery monitoring method and system, and the method comprises the steps that S1, a sensing unit detects the electric quantity and the discharge current of a storage battery in real time, judges whether the storage battery is abnormal or not according to the electric quantity and the discharge current of the storage battery, and when the storage battery is abnormal, generates a wake-up signal and sends the wake-up signal to the main node unit; S2, the main node unit reads an abnormal judgment result of the sensing unit according to the wake-up signal, and drives a self-holding relay to be disconnected according to the abnormal judgment result, wherein the controlled load is electrically connected with the storage battery through the self-holding relay. The electric quantity and the discharge current of the storage battery can be monitored, and when the electric quantity and the discharge current of the storage battery are abnormal, the power supply of the electric appliance load is actively controlled to be cut off.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle storage battery monitoring method and system thereof. Background technique [0002] The quiescent current has a great impact on the starting of the vehicle. When the battery is in good condition, the greater the quiescent current, the faster the energy consumption of the battery will be, because the battery is the only energy provider for the vehicle to start. As a result, the vehicle cannot be started, and in severe cases, it cannot be started normally after being left for a few hours. One of the things that can cause a vehicle to lose power is that some of the modules on the vehicle don't always go into "sleep mode" properly, thus drawing enough quiescent current to drain the battery. [0003] In the process of realizing the present invention, the inventor finds that the prior art has the following defects: [0004] At present, most models do not have effective man...
