Accompanying drawing explanation
Fig. 1 is the wiring diagram of this utility model-embodiment.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.Embodiment party of the present utility model
Formula includes but not limited to the following example.
Embodiment
As it is shown in figure 1, a kind of Air Condition Compressor for Electric Vehicle power distribution control system, including electrokinetic cell, open
Close one end by electric machine controller insurance pre-charge-relay K1 that is connected with power battery anode of F1, positive pole and
The buffer resistance R1 that powers on that the switch other end of pre-charge-relay K1 connects, respectively with the buffer resistance that powers on
Electric machine controller that the negative pole of R1 connects and air conditioner compressed machine controller, air conditioner compressed machine controller with power on
Connect between buffer resistance R1 and have compressor of air conditioner to insure F2；Also include that switching one end insures with electric machine controller
The switch other end of main relay K2, main relay K2 that F1 negative pole connects is connected to electric machine controller, sky
Adjust on the connection node of compressor controller, the buffer resistance R1 that powers on；Also include by CAN and air-conditioning
The car load logic control element VCU that compressor controller connects, this car load logic control element VCU and precharge
Coil one end of relay K 1, coil one end of main relay K2 connect, this car load logic control element VCU
It is connected with electrokinetic cell, electric machine controller, air-conditioning respectively also by CAN, pre-charge-relay K1
The coil other end, the coil other end ground connection of main relay K2, electric machine controller and air conditioner compressed machine controller
Negative pole connect power battery cathode.
In the present embodiment, support electricity in parallel between input positive pole and the input negative pole of air conditioner compressed machine controller
Hold, equally Support Capacitor in parallel between the input positive pole and input negative pole of electric machine controller.
This utility model mentality of designing is: why when starting air-conditioning, the height of air conditioner compressed machine controller is press-fitted
Can there is current impulse in electricity end, be because the input positive pole of air conditioner compressed machine controller with inputting negative pole in parallel
Support Capacitor, this electric capacity plays the effect of burning voltage and reactive-load compensation, it is impossible to cancel.The internal resistance of electric capacity is the least,
Therefore have when charging and there is the biggest current impulse.The main circuit of electric machine controller and compressor of air conditioner control
The main circuit of device processed is similar, there is also this Support Capacitor, therefore there is also current impulse when electrifying startup,
Therefore this utility model is configured with, to electric machine controller, the buffer circuit that powers on.Therefore, the distribution of air-conditioner controller
Can use the buffer circuit that powers on of electric machine controller, buffering power up is as follows:
1, after car load is key operated, VCU control K1 Guan Bi, electric current after resistance R1 give electric machine controller and
Support Capacitor charging within air conditioner compressed machine controller, now VCU starts to calculate charging interval T；
2, VCU knows the magnitude of voltage U1 of Support Capacitor by CAN simultaneously, by CAN and car load
The magnitude of voltage U2 of electrokinetic cell is known in BMS communication；
3, when the voltage difference U of U2 Yu U1 is less than setting value, and when charging interval T is more than setting value,
It can be assumed that charging complete, now after closing relay K2, postpone 1～3S disconnection relay K 1, in buffering
Electric process completes.
When starting air-conditioning, by the voltage difference U of U2 with U1, VCU judges whether main relay K2 closes,
Without Guan Bi, the most do not start air-conditioning, fault can be sent in the case of detection driver's key closes
Alarm signal；If closed, then can normally start air-conditioning.
According to above-described embodiment, this utility model just can be realized well.What deserves to be explained is, based on above-mentioned
On the premise of design principle, for solving same technical problem, even if in structure disclosed in the utility model
On the basis of make some without substantial change or polishing, the essence of the technical scheme used still with this
Utility model is the same, therefore it should also be as at protection domain of the present utility model.
