Show the schematic flow sheet of an embodiment of the method for supervising that powers on of a kind of electronlmobil of the present invention referring to Fig. 1.
In the present embodiment, this method comprises:
101: obtain the status information of the parts that power in the described electronlmobil, wherein, the status information of the described parts that power on comprises: the voltage of the DC bus-bar voltage of motor, the electric current of electrokinetic cell and/or electrokinetic cell.
The parts that power in the electronlmobil refer to participate in the automobile component that the electronlmobil high-pressure system powers on, and mainly comprise motor, electric machine controller, electrokinetic cell and battery controller.Wherein, the DC bus-bar voltage of motor can be obtained by electric machine controller, and corresponding, the electric current of electrokinetic cell and the voltage of electrokinetic cell also can obtain by battery controller.Electrokinetic cell adopts precharge mode that electric machine controller is powered in the present invention, the high pressure that is about to electrokinetic cell is loaded on the electric machine controller gradually, thereby avoided being loaded on the electric machine controller the high pressure of electrokinetic cell is instantaneous the situation that causes electric machine controller to damage.
102: it is pre-conditioned to judge whether described status information satisfies.
Wherein, in the operating process of reality, the type difference of the status information of obtaining, the asynchronism(-nization) of obtaining status information, the setting of this preset condition also can corresponding differences.Such as: when the status information of obtaining is the DC bus-bar voltage of motor, pre-conditionedly can be set to judge whether the DC bus-bar voltage of the motor that gets access to is zero before precharge.And for example, when the status information of obtaining during for the DC bus-bar voltage of this motor in pre-charge process, pre-conditionedly can be set to judge that whether the rate of rise of the DC bus-bar voltage of motor in the pre-charge process is greater than default rate of rise.
103: according to judged result, control described electrokinetic cell electric machine controller is powered on.
Wherein, the control electrokinetic cell comprises powering on of electric machine controller: the power up and interruption electrokinetic cell power up to electric machine controller of battery to electric machine controller turns on the power.
Before precharge, need obtain the power on status information of parts of electronlmobil, such as: whether the DC bus-bar voltage of motor, satisfy the condition that powers on the parts that power on of determining electronlmobil.When the parts that power on of determining electronlmobil by the status information of obtaining were fit to power on operation, the precharge of battery to electric machine controller turned on the power.
And in pre-charge process, the unusual situation of precharge may appear, thereby need obtain the status information of parts in pre-charge process that power on of electronlmobil, and judge according to the status information of obtaining whether pre-charge process is unusual.When definite this pre-charge process is unusual, then interrupt electrokinetic cell to the pre-charge process of electric machine controller.
Compared with prior art, this method is obtained the status information of the parts that power on of electronlmobil, wherein this status information comprises: the DC bus-bar voltage of motor, electrokinetic cell electric current and/or electrokinetic cell voltage, and judge whether the status information of obtaining satisfies pre-conditioned, and then, according to judged result monitoring electrokinetic cell electric machine controller is powered on, unlatching or interruption electrokinetic cell are to the power up of electric machine controller, thereby avoided the parts that power on of electronlmobil when being not suitable for powering on operation, to power on, and occur in the power up going up electrical anomaly, cause the situation of damaging the electronlmobil parts.
Before precharge, only be in when being fit to precharge state at definite electric machine controller, could allow electrokinetic cell that electric machine controller is carried out precharge, otherwise can damage the electric capacity of voltage regulation of electric machine controller inside.
Be fit to precharge state in order to determine whether electric machine controller is in, further, show the schematic flow sheet of another embodiment of method for supervising that powers on of a kind of electronlmobil of the present invention referring to Fig. 2.
Different with a last embodiment is that the status information of the parts that power on that obtain in the present embodiment is the DC bus-bar voltage of the motor before the precharge.
Its concrete steps are as follows:
201: before precharge, obtain the DC bus-bar voltage of described motor.
In practical operation, the DC bus-bar voltage of motor can be obtained by the electric machine controller that links to each other with motor.
202: whether the DC bus-bar voltage of judging described motor is zero.
There is electric capacity of voltage regulation in electric machine controller inside, usually with the electric weight of electric capacity of voltage regulation as judging whether electric machine controller is fit to carry out a precharge standard.When the electric weight of electric capacity of voltage regulation is non-vanishing, illustrate that electric machine controller is in down electric process, or last following electric process occurred unusually, cause the electric capacity of electric capacity of voltage regulation non-vanishing.Thereby have only when the electric weight of electric capacity of voltage regulation is zero, could carry out precharge operation to electric machine controller.Concrete, because the DC bus-bar voltage of motor can reflect the electric weight size of electric capacity of voltage regulation, thereby usually with the DC bus-bar voltage of the motor standard as the electric weight of weighing electric capacity of voltage regulation.When the d-c bus voltage value of motor was zero, the electric weight of then determining electric capacity of voltage regulation was zero, and then definite electric machine controller is fit to precharge operation.
203: when the DC bus-bar voltage of motor is zero, controls described electrokinetic cell described electric machine controller is carried out precharge, to finish powering on to described electric machine controller.
When the DC bus-bar voltage of motor is zero, then can determine to be fit to electric machine controller is carried out precharge.And then the control electrokinetic cell carries out precharge operation to electric machine controller, finishing the powering on of electric machine controller, and then after electric machine controller is finished precharge operation, and the operation that powers on of the electric machine controller pair motor that links to each other with this electric machine controller.
Further, after the precharge of electrokinetic cell startup to electric machine controller, in order at electrokinetic cell the pre-charge process of electric machine controller to be occurred when unusual, can in time interrupt precharge, to avoid damaging electric machine controller, can also in pre-charge process, according to the status information of the parts that power in the electronlmobil, determine whether to need to interrupt current precharge to electric machine controller.

Its concrete steps are as follows:
301: in pre-charge process, obtain the electric current of described electrokinetic cell.
In the present embodiment, the electric current of this electrokinetic cell obtains by the electrokinetic cell controller that links to each other with this electrokinetic cell.
302: judge that the electric current of described electrokinetic cell is whether in preset range.
Under desirable state, there is a precharge lowest high-current value in electrokinetic cell to the pre-charge current of electric machine controller, and this precharge lowest high-current value is determined by the voltage of electrokinetic cell and the resistance of the resistance in the precharge loop.When the electric current of the electrokinetic cell that obtains during less than this precharge lowest high-current value, illustrate that pre-charge process is normal; When the electric current of the electrokinetic cell that obtains during greater than this precharge lowest high-current value, illustrate that then pre-charge process has occurred unusually.
Therefore yet there is certain error in the electric current of considering the electrokinetic cell that collects, in practical operation, when the electric current of the electrokinetic cell that gets access to is in default scope, illustrates that pre-charge process is normal; When the electric current of the electrokinetic cell that obtains has exceeded preset range, illustrate that then pre-charge process has occurred unusually.
303: when the electric current of described electrokinetic cell exceeds preset range, interrupt described precharge.
When the electric current of electrokinetic cell had exceeded default scope, illustrated that pre-charge process is unusual this moment, should interrupt precharge, to guarantee the safety of electric machine controller.
Further, the present invention can also judge whether pre-charge process occurs unusually by obtaining the DC bus-bar voltage information of different motors constantly in the pre-charge process.Show the schematic flow sheet of another embodiment of the method for supervising that powers on of a kind of electronlmobil of the present invention referring to Fig. 4.The method of present embodiment comprises:

402: judge that whether first rate of rise of DC bus-bar voltage of described motor is greater than default rate of rise.
According to the DC bus-bar voltage of the different motors constantly that obtain, first rate of rise K, the wherein K=[U(t+i of the motor DC bus voltage in the computing time section i)-U(t)]/i, and relatively first rate of rise and default rate of rise.When first rate of rise during greater than default rate of rise, the DC bus-bar voltage that motor be described increases too fast, and precharge occurs unusual, needs to interrupt precharge this moment, with the safety of assurance electric machine controller.
403: when first rate of rise of the DC bus-bar voltage of described motor during greater than default rate of rise, interrupt described precharge.
Further, the present invention also can be by in pre-charge process, and the voltage of the electrokinetic cell that obtains and the DC bus-bar voltage of motor determine whether precharge is unusual.
In precharge process, obtain the DC bus-bar voltage of voltage and the motor of electrokinetic cell, and the absolute value of the difference of the DC bus-bar voltage of the voltage of comparison electrokinetic cell and motor and the magnitude relationship of predetermined threshold value.When the absolute value of the difference of the DC bus-bar voltage of the voltage of electrokinetic cell and motor during smaller or equal to predetermined threshold value, it is unusual to illustrate that pre-charge process to electric machine controller occurs, and interrupts precharge.Wherein, this predetermined threshold value can be according to default formula U=Ub*(| Δ Um|+| Δ Ub|) calculate and obtain.Ub is the voltage of electrokinetic cell, and Δ Um is the Acquisition Error of the DC bus-bar voltage of motor, and Δ Ub is the Acquisition Error of the voltage of electrokinetic cell.
Be understandable that, in pre-charge process for the safety of the power up that improves electronlmobil, can also obtain the DC bus-bar voltage of motor, the electric current of electrokinetic cell and the voltage of electrokinetic cell simultaneously, and as long as in the voltage of the electric current of DC bus-bar voltage, electrokinetic cell and electrokinetic cell any one satisfy pre-conditioned accordingly, all must interrupt pre-charge process, with the power on safety of parts of guarantee.
