Embodiment Construction

[0032] Such as figure 1 As shown, according to a preferred embodiment of the present invention, the present invention provides a method for monitoring the operating state of a vehicle circuit, the vehicle being an electric vehicle, comprising the following steps:

[0033] (1) Detect the battery terminal voltage of the electric vehicle;

[0034] (2) Detecting the device input voltage delivered to the electronic device of the electric vehicle;

[0035] (3) Comparing the input voltage of the device with a preset threshold value to determine the operating state of the vehicle circuit.

[0036] Preferably, said step (1) includes the steps of:

[0037] (10) The first full charge is carried out to the new battery after replacement, and the first group of electrical parameters {E of the battery are detected during the charging process 1} and the first set of temperature information {T 1}, determine the first battery characterization parameter V detected by the vehicle battery mana...

Abstract

The invention provides a monitoring method for the vehicle circuit running state in order to solve the problems that after a battery of an electric vehicle is replaced, battery mounting is not standard, battery management system parameters are short of adjusting and checking, and after battery replacing, a new battery needs to adapt to the power supply situation, so that electricity detection is not accurate, and safe operation of the vehicle is affected accordingly. The monitoring method comprises the steps that (1) the battery terminal voltage of the electric vehicle is detected; (2) the device input voltage of an electronic device transmitted to the electric vehicle is detected; and (3) the device input voltage is compared with a preset threshold value to determine the circuit running state of the vehicle.

Description

technical field [0001] The present invention relates to the technical field of electric vehicles, and more specifically, to a method for monitoring the running state of a vehicle circuit. Background technique [0002] Electric vehicles have become the focus and focus of global development. In order to meet the demand of high-power electric drive, the current passing through the high-voltage circuit of the car is as high as hundreds of amperes. High-voltage safety has become the key technology that needs to be solved first in the application of electric drive vehicles, and has a very important impact on the safety of the vehicle itself, the safety of drivers and passengers, and the safety of the vehicle operating environment. At present, although there are detection and diagnosis methods for high-voltage safety faults such as high-voltage circuit connection resistance faults and insulation resistance faults, there is a lack of comprehensive characterization methods and diagn...
