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...
