Problems solved by technology
[0004] Due to the difference in experience value due to personnel differentiation, and the development of power management technology leads to the failure of experience, it makes it more difficult to diagnose the power supply system after sales, resulting in an increase in misjudgment rate or the inability to quickly identify problems
The increase in misjudgment rate will lead to a large number of normal parts being claimed, which will increase the after-sales cost
Failure to quickly fix the problem will lead to increased after-sales workload and complaints from car owners

Embodiment Construction
[0078] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0079] like figure 1 As shown, it shows a schematic diagram of the main flow of an embodiment of a method for quickly detecting the state of a charging system provided by the present invention, combined with Figure 2 to Figure 5 shown. In this embodiment, the method for quickly detecting the state of the charging system includes the following steps:
[0080] Step S10, after the detection device is connected to the OBD interface (on-board diagnostic system interface) of the vehicle, and after the vehicle is powered on, the rapid detection process in the detection device is triggered;
[0081] Specifically, in an example, the vehicle is firstly powered on, and the detection device is connected to the vehicle through a unified diagnostic service protocol (OBD), an...

The invention provides a method for rapidly detecting the state of a charging system. The method comprises the following steps: S10, triggering a rapid detection process in detection equipment; S11, reading battery information of the vehicle, and performing battery code proofreading; S12, after the vehicle is in the static working condition, collecting battery state information, and obtaining a static working condition judgment result; S13, after the vehicle starts an engine and enters a stable idling working condition, collecting state information of a storage battery and state information of a generator, and obtaining a first dynamic working condition judgment result; S14, controlling the engine to increase the rotating speed to a preset rotating speed, collecting the state information of the storage battery and the state information of the generator, and obtaining a second dynamic working condition judgment result; and S15, performing comprehensive analysis according to the judgment result to obtain a final judgment result. The invention further provides a corresponding system. According to the invention, the judgment result of the state of the charging system can be quickly and accurately obtained, and the after-sales maintenance efficiency can be improved.
Description
technical field [0001] The invention relates to the technical field of power supply systems for fuel vehicles, in particular to a method and system for quickly detecting the state of a charging system. Background technique [0002] At present, the traditional automotive power supply system components are mainly composed of batteries and generators. During the user's use, the charging system fault indicator displayed on the instrument can remind the user or guide the service shop to perform maintenance: among them, the charging system fault indicator only monitors the generator. For example, the externally excited generator monitors the excitation current, and the self-excited generator only monitors the fault status fed back by the generator. None of the above monitoring can directly represent the actual failure of the generator and cause it to fail to work normally; [0003] In the after-sales maintenance and repair links, operators generally judge the status of the power ...
