Below in conjunction with accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, the operation principle of the present invention is further solved
Release.
The operation principle of high pressure display unit is described as a example by direct current transducer DC1: when the electric power storage of electric automobile
The electric current of the output of pond E1 is loaded into the high input voltage of DC converter DC1 and inserts by crossing stream identification protecting unit
On head, now there is following result: the high voltage input terminal socket of (1) direct current transducer DC1 does not access, this
Time, light emitting diode D23 bright light (green light), illustrate from the positive pole of set of cells E1 to direct current transducer DC1
The wire harness of high input voltage plug make and connect correct, and the both positive and negative polarity of set of cells E1 does not has wiring wrong yet
By mistake (this mode is used for checking that wire harness is corrected errors)；(2) access when the high voltage input terminal socket of direct current transducer DC1
After, i.e. the input of the input of direct current transducer DC1 and high pressure display unit and overcurrent protection identification list
The battery output A2 of unit connects, and light emitting diode D23 continues bright light, then it represents that direct current transducer DC1
Input does not has short-circuit conditions, and the outfan such as now direct current transducer DC1 does not has low pressure to export, then show
There is open circuit situation in the high voltage input terminal of direct current transducer DC1, it should emphasis checks direct current transducer DC1's
Input；(3) the high voltage input terminal socket such as direct current transducer DC1 does not access, light emitting diode D22,
Light emitting diode D23 does not has bright, illustrates to insert from set of cells E1 to the high voltage input terminal of direct current transducer DC1
The wire harness of seat has making mistake, makes high pressure be not applied to light emitting diode D22's and light emitting diode D23
Two ends, it is necessary to check the making mistake of wire harness；Such as light emitting diode D22 bright light (red light), and light-emitting diodes
Pipe D23 does not works, then show that the both positive and negative polarity of set of cells E1 connects instead, it is necessary to correct；For other high pressure zero
Parts, such as DC converter DC2, DC converter DC3, compressor controller, PTC controller and electricity
The inspection principle of machine controller etc. is identical with DC converter DC1, and not in this to go forth.
The inspection principle of low pressure display unit is identical with the inspection principle of high pressure display unit, direct current transducer
The low-voltage that DC1 and direct current transducer DC2 and direct current transducer DC3 each exports respectively with low-voltage load
(low-voltage electrical apparatus) connects, and therefore, needs also exist for carrying out low pressure inspection, and low tension when testing
Gas includes ACC, IG1, IG2 and three direct current transducers that key switch controls, wherein direct current conversion
The low pressure detection of device DC3 is reacted by FS8, the low pressure of DC converter DC1 is checked as it is shown in figure 1,
By resistance R11, diode D10 (the second light emitting diode) and light emitting diode D11 (the first luminescence two
Pole is managed) the low pressure display unit that forms tests, the high pressure inspection of its inspection principle and direct current transducer DC1
Testing identical, certainly, the inspection principle of other low pressure parts is also according to same principle.
Below in conjunction with Fig. 2 and Fig. 3, the operation principle of overcurrent protection module is described:
The input A3 of described AC/DC conversion voltage regulation unit is connected with live wire, and input A5 is connected with zero line,
220V alternating current is exported the voltage of two 13V by AC/DC conversion voltage regulation unit by the effect of transformator T1,
Then the rectifier bridge constituted by diode D1, diode D2, diode D3 and diode D4, and pass through
Manostat V1 and the effect of manostat V2, after on and off switch K1 closes, in the output of manostat V1
End A9 exports+12V voltage, and the output terminals A 7 at manostat V2 exports-12V voltage, and identifies to crossing stream
Protected location is powered；
After examined wire harness or electric components connect, press on and off switch K1 and high-voltage switch gear K2,
The normally opened contact Guan Bi of A.C. contactor J1, the high pressure of the set of cells E1 electricity by overcurrent protection recognition unit
Cell voltage input A1 and cell voltage output terminals A 2 are loaded into checked parts, and DC current
The current signal of sensor V4 detection accumulator now, and by resistance R2 and resistance R3 by current signal
It is converted into voltage signal and is input to the in-phase end of amplifier V5, and the comparator that formed by amplifier V5 and benchmark
Voltage compares, and this reference voltage is that 12V voltage carries out dividing potential drop setting also by resistance R5 and resistance R4
It is loaded into the end of oppisite phase of amplifier V5, when the in-phase end voltage of amplifier V5 is less than end of oppisite phase voltage, amplifier V5
It is output as 0, shows that the high pressure of parts checks electric current in allowed limits, now audion V3 cut-off,
DC relay J2 does not works, so that the normally-closed contact of DC relay J2 is kept closed, electrically
The Function detection of parts continues, now the outfan of manostat V1 by the coil of DC relay J3 and
Light emitting diode D8 is made to obtain electric holding lighting lamp state (green light) after resistance R10,
In checking, there is short trouble in the parts of arbitrary high voltage supply, the now in-phase end voltage of amplifier V5
More than end of oppisite phase voltage, amplifier V5 output voltage is become 12V from 0V, and is charged electric capacity C5, when
When the voltage of electric capacity C5 rises to certain voltage value, audion V3 and audion V6 conducting, DC relay
J2 and DC relay J3 all electric work, the normally closed contact point J2-1 of DC relay J2 disconnects, and hands over
Stream catalyst J1 thus be de-energized, the normally opened contact point J1-1 of A.C. contactor J1 return to normally open from
And the high-tension current of accumulator E1 disconnects power supply, DC relay J3 works, its normally opened contact J3-1 quilt
Adhesive ,+12V the voltage of manostat V1 output is loaded into electric capacity C5, makes audion V3 and audion V6
Persistently tend to remain on, so that it is guaranteed that the supply access of accumulator E1 continues to be disconnected, now light-emitting diodes
Pipe D8 extinguishes, and light emitting diode D9 is luminous (HONGGUANG), and this process is continued until on and off switch K1 and height
The K2 that compresses switch closes, and now may determine that the parts of current detection break down or damage, needs to carry out
Maintenance, after the fault of parts is excluded, after on and off switch K1 and high-voltage switch gear K2 restarts,
Light emitting diode D8 is the most luminous, and diode D9 extinguishes；When current detected parts are normal, and
When amplifier V5 is output as O, light emitting diode D8 exports+12V voltage in luminescence due to manostat V1
By making light emitting diode D8 obtain electric current, two now after the coil of DC relay J3 and resistance R10
The operating current of the pole pipe D8 operating current much smaller than DC relay J3, therefore, even if now luminescence two
Pole pipe D8 is in running order and DC relay J3 still will not work, and the normally opened of DC relay J3 touches
Point J3-1 will not be by adhesive.
Finally illustrate, above example only in order to technical scheme to be described and unrestricted, although
With reference to preferred embodiment, the present invention is described in detail, it will be understood by those within the art that,
Technical scheme can be modified or equivalent, without deviating from technical solution of the present invention
Objective and scope, it all should be contained in the middle of scope of the presently claimed invention.
