Judge new-energy automobile can not charge fault when, two interfaces of detection box are coupled with and vehicle-mounted charge mouth and are filled
On electric rifle, switch S1-S5 is then in turn switched on, while signal is detected on detection terminal to judge that failure is by which
Caused by side: 1, detect has L firewire, N zero curve, PE protective ground wire, CC charging connection confirmation line, CP control confirmation respectively on box
Line, 5 are guided to the line of terminal box.This 5 lines are detection box input lines, whether there is event when measuring one in this five routes
When barrier, respectively can in the terminal mouth in detection box using multimeter measurement L, whether export with N voltage, in this way it may determine that
L, whether normal with the two lines in N.Same reason, to survey PE line whether can normally survey voltage-to-ground and PE to CC or
To CP and CP, whether short circuit, open circuit and detection box end are whether route and voltage are normal to charger end to CC over the ground.If sentenced
Whether disconnected vehicle end is normal, can also be in the CC and CP and PE letter of the output port test point measurement vehicle-mounted charge generator terminal of detection box
It is number whether normal.It is whether normal at the same time it can also the voltage that measures L and N；2, opening by S1 to the S5 on circuit diagram
It closes, purpose is exactly after imparting knowledge to students or simulating the open circuit of L, N, PE, CC, CP line when judging failure, what vehicle end will occur
Phenomenon of the failure；It also may determine that the fault point after one group of line disconnects among these simultaneously.It should be noted that S1 to S5 switch is all
It is that can be each turned off regardless of sequence, only the phenomenon of the failure that disconnects is different.
Need specifically judge which group route of on-board charging system or charging gun causes failure, when formation maintenance program,
The input signal of normal work can be simulated, uses ten thousand by connecting or disconnecting this four switches of switch S6/S7/S10/S11
Output signal is detected in detection terminal with table, by analyzing which line fault is output signal determine.Switch S6 and S7 switch close
It is indirectly short-circuit that conjunction will be considered to CP and PE line, detects to detection terminal, if voltage value is more than normal value, in this way it may determine that
This group of line failure；It is indirectly short-circuit that switch S10 closure will be considered to CC and PE line, detects to detection terminal, if voltage value is more than
Normal value, in this way it may determine that this group of line failure.
For charge fault, there are one the vehicle-mounted type insulation monitoring systems that reason is exactly vehicle itself to break down, can not
Electric voltage exception is monitored；And when needing to detect vehicle-mounted type insulation monitoring system and whether working normally, pass through and connects switch S8/
S9, if there is insulation fault warning note in instrument, prove it is working properly, conversely, work it is abnormal.Principle is just comparable to
Simulate a branch pressure voltage to Vehicular charger to onboard charger end, to judge indirectly with this failure thus put where: 1, root
Connecting S8 switch according to schematic diagram means that chassis ground PE and N zero curve is indirectly short-circuit, and N is connect with PE means that zero curve and ground are formed
Circuit will represent at this time it is internal connect with ground forming circuit will will lead to vehicle in electric leakage forming circuit and have danger of hazardous electrical discharges,
It is exactly insulation fault；2, L line will lead to according to schematic diagram connection S9 switch and PE line connects ground wire at this time and alternating current firewire indirectly
It is most dangerous that connection, which will lead to shell and forming circuit be leaked electricity at this time with the connection of single line firewire,.Direct insulation fault will lead to
Electric shock, addition resistance can protect circuit safety.
It should be understood that the effect of six resistance in detection circuit is protection detection circuit, open circuit or short is prevented
Cause the danger of high-voltage destruction circuit in road.
The utility model judges detection terminal progress signal detection by being switched on or switched off the switch of detection line road
Where the problem of failure of charging, the skill that traditional detection method can not fast and effeciently detect automobile charge fault is solved
Art problem, to efficiently, more accurately be detected to vehicle failure.
Particular embodiments described above has carried out into one the purpose of this utility model, technical scheme and beneficial effects
The detailed description of step, it should be understood that the foregoing is merely specific embodiment of the utility model, be not used to limit this reality
With novel protection scope.Particularly point out, to those skilled in the art, it is all the spirit and principles of the utility model it
Any modification, equivalent substitution, improvement and etc. that are interior, being done, should be included within the scope of protection of this utility model.
