Description
Technical field
The invention belongs to vehicle trouble investigation and the fields of processing, and in particular to a kind of pure electric vehicle investigation Insulation Problems
Processing method.
Background technology
Currently, pure electric vehicle has slowly entered city to solve the pollution condition that traditional oils vehicle is brought, therefore pure electricity
The repair of motor-car also slowly enters the scope of 4 S auto shop repair, after pure electric vehicle goes wrong, now to pure electric vehicle
Repair, first use failure diagnosis tool read failure code, then use vehicle detection software check vehicle insulate, measure high pressure
Attachment insulation values and battery pack insulation values judge which Insulation Problems partly occurs according to insulation values, but most 4 S auto shops
Fault diagnosis equipment is only provided, the instrument of vehicle inspection software is not provided, therefore it is soft not provide in 4 S auto shop vehicle detection
The insulation fault investigation of pure electric vehicle is difficult in the case of part.
In view of this, special propose the present invention.
Invention content
The object of the present invention is to provide the processing methods that a kind of pure electric vehicle investigates Insulation Problems, by high pressure attachment
Insulation Problems judge, to judge the insulation performance of vehicle, greatly improve investigation and troubleshooting efficiency, need not use insulation inspection
Instrument is surveyed, avoids causing high pressure accident using instrument is improper, solves the pure electric vehicle in the case where not providing vehicle inspection software
The difficult problem of insulation fault investigation.
To achieve the goals above, the processing method of a kind of pure electric vehicle investigation Insulation Problems provided by the invention, including
Following steps：
(1) under electric vehicle detecting state, start automobile fault diagnostic apparatus；
(2) high-voltage connector of all high pressure attachmentes is disconnected, provides high-voltage electricity to Vehicular battery packet, detects the battery
Whether packet has insulation obstacle, and investigation result is obtained if there is insulation obstacle and terminates to investigate, otherwise carries out next step；
(3) Vehicular battery packet and high-voltage electricity are disconnected, the high pressure of some high pressure attachment to be detected is patched
Part is closed, and the high-voltage connector of remaining high pressure attachment disconnects, and whether detect the high pressure attachment has insulation obstacle, if there is insulation
Obstacle, which then obtains investigation, result and to be terminated to investigate, on the contrary then carry out next step；
(4) step (3) is repeated to the high pressure attachment not detected, until having investigated all high pressure attachmentes.
Further, high pressure attachment includes DC/DC converters, compressor and PTC devices.
Preferably, at the end of investigation, the high-voltage connector of battery pack and all high pressure attachmentes need to all be disconnected.
A kind of processing method of pure electric vehicle investigation Insulation Problems provided by the invention, has the advantages that：
1, by the Insulation Problems judgement to high pressure attachment, to judge the insulation performance of vehicle, investigation and event are greatly improved
Hinder treatment effeciency；
2, insulation tester need not be used, avoids causing high pressure accident using instrument is improper；
3, in the case where not providing vehicle inspection software, the insulation fault investigation of pure electric vehicle is easy and operable.
Specific implementation mode
In order to enable those skilled in the art to better understand the solution of the present invention, With reference to embodiment to this hair
It is bright to be described in further detail.
A kind of processing method of pure electric vehicle investigation Insulation Problems, electric vehicle instrument, which is shown, cannot lead to high-voltage electricity, then electric
There is insulation fault in motor-car, need not use vehicle inspection software at this time, and the exhausted of electric vehicle is investigated using automobile fault diagnostic apparatus
Reason hinders, and the processing method for investigating Insulation Problems includes the following steps：
(1) high-voltage connector for disconnecting DC/DC converters, compressor and PTC devices provides high pressure to Vehicular battery packet
Whether electricity, detection Vehicular battery packet have insulation fault, illustrate that Vehicular battery packet breaks down and ties if there are insulation fault
Beam is investigated, on the contrary then carry out next step.Battery pack, which is investigated, by step (1) whether there is insulation fault.
(2) if insulation fault is not detected in step (1), the high-voltage connecting of Vehicular battery packet, compressor and PTC devices is disconnected
The high-voltage connector of DC/DC converters is closed by plug-in unit, provides high-voltage electricity to DC/DC converters, whether detection vehicle has insulation
Failure illustrates that DC/DC converters break down and terminate to investigate if there are insulation fault, otherwise carries out next step.
DC/DC converters, which are investigated, by step (2) whether there is insulation fault.
(3) if insulation fault is not detected in step (2), Vehicular battery packet, DC/DC converters and PTC devices are disconnected
The high-voltage connector of compressor is closed by high-voltage connector, provides high-voltage electricity to compressor, whether detection vehicle has insulation event
Barrier illustrates that compressor breaks down and terminates to investigate if there are insulation fault, otherwise carries out next step.Pass through step
(3) investigation compressor whether there is insulation fault.
(4) if insulation fault is not detected in step (3), the height of Vehicular battery packet, DC/DC converters and compressor is disconnected
Plug-in unit is crimped, by the high-voltage connector closure of PTC devices, provides high-voltage electricity to PTC devices, whether detection vehicle has insulation event
Barrier illustrates that PTC devices break down and terminate to investigate if there are insulation fault, otherwise carries out other investigations.Pass through step
Suddenly (4) investigation PTC devices whether there is insulation fault.
When terminating investigation, all high-voltage connectors need to be disconnected, ensure vehicle safety after investigation.By controlling vehicle
Disconnection and the closure of battery pack, DC/DC converters, compressor and PTC devices and high-voltage connector investigate each of electric vehicle one by one
A device whether there is insulation fault.
Specific case used herein elaborates inventive concept, the explanation of above example is only intended to
Help understands core of the invention thought.It should be pointed out that for those skilled in the art, not departing from this
Under the premise of inventive concept, any obvious modification, equivalent replacement or the other improvements made should be included in the present invention
Protection domain within.
