Embodiment 1

[0042] This embodiment provides a fault detection method for a wireless controller of an electric vehicle, such as figure 2 shown, including the following steps:

[0043] Open the second connection port 400 and the first connection port 200;

[0044] The first connection port 200 and the second connection port 400 are respectively detachably connected to both ends of the maintenance adapter 1, and each wire to be tested on the main wiring harness 300 can be respectively connected to the wireless controller 100 through the maintenance adapter 1 , and can connect the wires to be tested one by one;

[0045] Detect the connected wires to be tested;

[0046] Troubleshoot and repair faults;

[0047] Remove the maintenance adapter 1;

[0048] The second connection port 400 is connected to the first connection port 200 .

[0049] The maintenance adapter 1 is detachably connected to the first connection port 200 and the second connection port 400, realizing the connection between...

Embodiment 2

[0058] The difference between this embodiment and Embodiment 1 is that, as Figure 4 As shown, on the basis of Embodiment 1, it also includes: before opening the second connection port 400 and the first connection port 200, define and number the wires to be tested, so as to prevent omission or repeated detection and improve the troubleshooting efficiency.

[0059] Optionally, before connecting the first connection port 200 and the second connection port 400 to the maintenance adapter 1, it also includes: defining and numbering the third port 13 and the fourth port 14, in case the main wiring harness 300 The wrong connection between the wire and the wireless controller 100 affects the detection effect. In this embodiment, each wire of the main wire harness 300 corresponds to a component on the wireless controller 100, the fourth port 14 corresponds to each wire of the main wire harness 300, and the third port 13 corresponds to the components on the wireless controller 100. Cor...

Abstract

The invention discloses a fault detection method for an electric vehicle wireless controller, which belongs to the technical field of electric vehicle maintenance. The fault detection method for the electric vehicle wireless controller comprises the following steps that a second connection port and a first connection port are opened; the first connection port and the second connection port are detachably connected to the two ends of the maintenance adapter respectively, and all to-be-tested wires on the main wire harness can be correspondingly connected to the wireless controller through the maintenance adapter and can be connected with the to-be-tested wires one by one; the connected to-be-tested wire is detected; troubleshooting a fault and maintaining the fault are carried out; the maintenance adapter is taken down; and the second connection port is connected with the first connection port. The fault detection method for the electric vehicle wireless controller is simple and convenient to operate, avoids the hidden dangers of wire cutting and adhesive tape winding during maintenance, and improves the safety performance of the electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicle maintenance, in particular to a fault detection method for a wireless controller of an electric vehicle. Background technique [0002] Along with the extensive use of electric vehicle, produced a large amount of maintenance work thereupon. The electric vehicle wireless controller and the main wiring harness are connected through the connection port. When there is a problem with the connection, because the copper terminals in the connector are difficult to pick out, the maintenance worker can only cut part of the wires of the main wiring harness in the actual maintenance process to find the fault. Reason, then connect the wires, wrap the connecting wires with tape to prevent leakage. When using the above method for maintenance, first, the original wiring harness will be destroyed in the troubleshooting process, which reduces the firmness of the cut wires and leaves a potential safety haza...
