Problems solved by technology

[0003] The power battery assembly is an important part of the vehicle. There are usually fuses in the vehicle to protect the important parts of the vehicle from abnormalities and failures. Since the fuse is a long-term load device, the life of the fuse will continue with the use process. Attenuation, if the life of the fuse ends when the vehicle is running, the vehicle will stall and accidents are extremely prone to occur

Embodiment Construction

[0052] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] refer to figure 1 , shows a flow chart of the steps of Embodiment 1 of a vehicle fuse monitoring method according to the present invention, which may specifically include the following steps:

[0054] Step 101, obtaining the current value and duration of the overload current impact flowing through the fuse of the vehicle;

[0055] A fuse is an overcurrent protection device connected in series in the circuit to be protected. The fuse contains a metal melt. When the current of the protected circuit exceeds the rated value and after a certain period of time, the heat generated by the melt itself will fuse the melt to disconnect the circuit, thereby playing a protective role.

[0056] Overload current impact refers to the cur...

Abstract

The embodiment of the invention provides a vehicle fuse protector monitoring method and device. The method comprises the steps that the current value and the time duration of overload current impactsflowing through a vehicle fuse protector are obtained; according to the overload current impact current value and time duration, the loss life proportion of the fuse protector is determined; accordingto the loss life proportion, the residual life proportion of the fuse protector is determined; and according to the residual life proportion of the fuse protector, the first state of the fuse protector is determined, reminding of timely replacement of the fuse protector can be conducted according to first state of the fuse protector, and the serious consequence caused by accidental failures of the fuse protector is avoided.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle fuse monitoring method and a vehicle fuse monitoring device. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuel as the power source. For example, the power battery assembly is used as the driving energy of the vehicle. The power battery assembly stores a large amount of electricity, and the voltage is generally above 400V, which belongs to high-voltage electrical applications. [0003] The power battery assembly is an important part of the vehicle. There are usually fuses in the vehicle to protect the important parts of the vehicle from abnormalities and failures. Since the fuse is a long-term load device, the life of the fuse will continue with the use process. Attenuation, if the life of the fuse ends when the vehicle is running, the vehicle will stall and accidents are extremely prone to occur. Contents of the ...
