Problems solved by technology

Due to the need to meet the temperature required for the normal operation of the on-board device in the limited compartment space of the vehicle, a cooling fan is usually installed on the on-board device. Electric vehicles are particularly sensitive to temperature and heat. When the cooling fan fails and is not dealt with in time, it is easy to cause electric The on-board device of the car suffers from high temperature downtime and burnt parts, etc.

Embodiment Construction

[0061] 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.

[0062] refer to figure 1 , which shows a flow chart of the steps of an embodiment of a method for handling a cooling fan failure according to the present invention, which may specifically include the following steps:

[0063] Step 101, obtaining the actual air volume information of the cooling fan collected by the air volume sensor;

[0064] As an example, electric vehicles are very sensitive to temperature and heat. Therefore, it is necessary to obtain the temperature of the battery and motor of the electric vehicle in real time to avoid high-temperature downtime and component burnout caused by excessive temperature. Currently, cooling fans are usually installed on the vehicle-mounted devices in order to control the heat dissipati...

Abstract

Embodiments of the present invention provide a method and device for troubleshooting a cooling fan, by obtaining the actual air volume information of the cooling fan collected by the air volume sensor, and then comparing the actual air volume information with the preset air volume information to generate an air volume for the actual air volume information Deviation value, when the component deviation value is greater than the first preset threshold, the first fault information for the cooling fan is generated and displayed on the central control screen, so that the fault information of the car cooling fan can be displayed to the user in time, so that the user can get Know the fault information of the car cooling fan and check it in time.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a cooling fan failure handling method and a cooling fan failure handling device. Background technique [0002] With the development of new energy sources, electric vehicles are becoming more and more popular. Due to the need to meet the temperature required for the normal operation of the on-board device in the limited compartment space of the vehicle, a cooling fan is usually installed on the on-board device. Electric vehicles are particularly sensitive to temperature and heat. When the cooling fan fails and is not dealt with in time, it is easy to cause electric The on-board device of the car has high temperature downtime and parts burnt. [0003] Therefore, there is a need for a method that can timely and accurately inform the user of the failure of the cooling fan of the electric vehicle. Contents of the invention [0004] In view of the above problems, embodi...
