Seeing Fig. 1, the flow process for the electric equilibrium control method of the electrokinetic cell of embodiment of the present invention offer is illustrated
Figure, the method can be applicable to the parallel oil-electric vehicle of single shaft, and Fig. 2 is that the parallel mixing of single shaft is moved
Power assembly structure chart, hybrid power assembly structure mainly include electromotor, automatic clutch, power motor,
Auto-manual change speed gear box (Automated Mechanical Transmission is called for short AMT), power current
Ponds etc., wherein power motor can not only be used for motor use, can use as electromotor again.Described power current
The electric equilibrium control method in pond includes:
Step 101: determine that the electric charge at the SOC value place of electrokinetic cell divides scope.
In embodiments of the present invention, first according to battery operated scope (the such as SOC of electrokinetic cell manufacturer's recommended
Between 30%-70%), battery operated scope is divided into four sections: first paragraph be SOC value between 0%-35%,
Second segment be SOC value between 35%-55%, the 3rd section be SOC value between 55%-70%, the 4th section is SOC
Value more than 70%, the purpose so divided be exactly when driving guarantee SOC value of battery without departing from
This recommended range of 30%-70%, shown in the electric equilibrium mode under different SOC scopes shown in Figure 3 and Fig. 4
Electric equilibrium control strategy schematic diagram.
Step 102: if the SOC value of electrokinetic cell is more than or equal to the first charge threshold and less than or equal to the second electric charge
Threshold value, then hybrid vehicle uses the method for operation that pure electronic starting combines with energy regenerating.Wherein,
Described first charge threshold is more than or equal to the lower limit of described electrokinetic cell normal range of operation, described second electricity
Lotus threshold value is less than the higher limit of described electrokinetic cell normal range of operation.
In conjunction with Fig. 3 and Fig. 4, it is the non-normal working scope of electrokinetic cell owing to SOC value is less than 30%, so should
Ensure that SOC is not less than 30% as far as possible, therefore, it can SOC=35% as the lower limit marginal value of battery electric quantity,
Can certainly be that other is more than the value of the 30% lower limit marginal value as battery electric quantity；SOC value is higher than 70% also
The non-normal working scope of electrokinetic cell, so should ensure that SOC value is not above 70%, therefore, it can by
SOC=55% is as the upper critical value of battery electric quantity, naturally it is also possible to be that other is less than the value of 70% as battery
The upper critical value of electricity.
Assume 30% to be the lower limit of electrokinetic cell normal range of operation, 70% for electrokinetic cell normal range of operation
Higher limit, 35% be described first charge threshold, 55% for described second charge threshold, then work as electrokinetic cell
SOC value when being between normal and safe scope 35%-55%, hybrid vehicle uses pure electronic starting
Mode with energy regenerating carries out the balance of SOC value of battery, the i.e. electric energy of energy regenerating can meet pure electricity substantially
The electric energy that dynamic starting is consumed.
Owing to described energy regenerating is the key of hybrid vehicle fuel-economizing, so SOC is at this model of 35%-55%
Enclose and interior all recover energy with larger current.Therefore, in embodiments of the present invention, big when described SOC value
In equal to the first charge threshold and less than or equal to the second charge threshold time (such as 35≤SOC≤55%), described
The recovery electric current of energy regenerating is more than current threshold, i.e. is defined by described current threshold and reclaims electric current
Size, so that hybrid vehicle utilizes electrokinetic cell to reclaim electric energy as early as possible with larger current, additionally, return
Receive electric current to be inversely proportional to described SOC value.
And SOC is when 35%-55% is in the range of this, it is dynamic to consume that the balance of SOC relies primarily on pure electronic starting
The electric energy of power battery, the technological means of employing is: when SOC value is relatively low, early terminates pure electronic starting, when
When SOC value is higher, evening terminates pure electronic starting.Therefore, in embodiments of the present invention, big when described SOC value
In equal to the first charge threshold and less than or equal to the second charge threshold time (such as 35≤SOC≤55%), use
First duration of described pure electronic starting is directly proportional to described SOC value, so controls according to the size of SOC value
The time of pure electronic starting, make SOC value control at 35≤SOC≤55% in the range of this as far as possible.
Visible, at 35%-55% in the range of this, neither carry out mixed dynamic generating and the most do not carry out mixed dynamic power-assisted, one
Aspect can avoid discharge and recharge frequent to battery to cause the reduction of battery life, on the other hand can improve power
The system effectiveness of assembly is (although it could be theoretically argued that mixed dynamic generating/mixed dynamic power-assisted can improve power assembly is
System efficiency, but be difficulty with in actual vehicle), thus improve car load economy.
Step 103: if described SOC value is less than described first charge threshold, then hybrid vehicle uses and comprises
Mixed dynamic generating is in the interior method of operation.
In conjunction with Fig. 3 and Fig. 4, when SOC is less than 35% (described first charge threshold), in order to prevent power current
Power consumption is continued in pond, and pure electronic starting can be converted to the starting of pure electromotor, and hybrid vehicle is expert at
Carry out mixed dynamic generating when sailing, SOC value so can be adjusted to more than 35% faster.Therefore, in step 103
In, if described SOC value is less than described first charge threshold, then hybrid vehicle employing pure electromotor starting,
The method of operation that mixed dynamic generating and energy regenerating combine.
Step 104: if described SOC value is more than described second charge threshold, then hybrid vehicle uses and comprises
Mixed dynamic power-assisted is in the interior method of operation.
In conjunction with Fig. 3 and Fig. 4, when described second charge threshold is 55%, if electrokinetic cell normal range of operation
Lower limit be 70%, it is assumed that 70% is tricharged threshold value, then as 55% ＜ SOC ＜ 70%, now SOC value
Higher, in order to make SOC value reduce, the opportunity that first pure electronic starting terminated postpones, and makes electrokinetic cell as far as possible
Power consumption, increases mixed electric boosting function simultaneously, and two functions all carry out power consumption, can under conditions of normal driving
Meet the needs that SOC reduces；It addition, in this range, how energy recovery function still recovers energy to the greatest extent,
Only just the recovery electric current of electrokinetic cell is reduced when SOC is close to 70%, and make when more than or equal to 70%
The recovery electric current zero setting of electrokinetic cell, thus ensure that SOC value is not over 70%.Based on this content, in step
In 104, if described SOC value is more than described second charge threshold and less than tricharged threshold value (55% ＜ SOC
＜ 70%), then hybrid vehicle uses the operation that pure electronic starting, mixed dynamic power-assisted and energy regenerating combine
Mode；If described SOC value is more than or equal to described tricharged threshold value (SOC >=70%), then hybrid vehicle
Use the method for operation that pure electronic starting and mixed dynamic power-assisted combine；Wherein, described tricharged threshold value is institute
State the lower limit of electrokinetic cell normal range of operation.
From foregoing teachings, when 35≤SOC≤55%, the recovery electric current of described energy regenerating is more than electric current
Threshold value, in order to recover energy with larger current.And as 55% ＜ SOC value ＜ 70%, although still need
How to recover energy to the greatest extent, but owing to SOC value now is already close to the lower limit of electrokinetic cell normal range of operation
Value 70%, compare this scope of 35≤SOC≤55%, should relatively subtract in the range of this in 55% ＜ SOC value ＜ 70%
Reclaim electric current less, and when close to 70%, the recovery electric current of electrokinetic cell is reduced, therefore, at this as far as possible
In bright embodiment, when described SOC value is more than described second charge threshold and is less than tricharged threshold value
(55% ＜ SOC value ＜ 70%), the recovery electric current of described energy regenerating mode is less than described current threshold, and described
Reclaim electric current to be inversely proportional to described SOC value.
From foregoing teachings, when 35%≤SOC≤55%, use the first duration of described pure electronic starting
Be directly proportional to described SOC value, i.e. when SOC value more hour, the time of pure electronic starting is shorter, when SOC value is got over
Time big, the time of pure electronic starting is longer, in order to make SOC value try not less than 35%.And as 55% ＜ SOC
During ＜ 70%, now SOC value is higher, and in order to make SOC value reduce, the opportunity that first pure electronic starting terminated postpones,
Make electrokinetic cell try one's best power consumption, same when SOC value more hour, the time making pure electronic starting is shorter, works as SOC
When being worth the biggest, the time making pure electronic starting is longer.But the pure electronic starting of 55% ＜ this scope of SOC ＜ 70%
Time should be greater than the start-up time of this scope of 35%≤SOC≤55%, in order to makes SOC value try not to be higher than
70%, therefore, in embodiments of the present invention, when described SOC value is more than described second charge threshold and less than the
During tricharged threshold value (55% ＜ SOC ＜ 70%), use the second duration of described pure electronic starting and described SOC value
Being directly proportional, wherein, described second duration is more than described first duration.
The electric equilibrium control method of the electrokinetic cell that the embodiment of the present invention provides, by different SOC range sections
In different ways electrokinetic cell SOC value is balanced, i.e. in SOC target zone (such as
35%-55%) use pure electronic starting and energy regenerating to realize the electric equilibrium of electrokinetic cell, surpass in SOC value
Use the mode combining mixed dynamic generating and mixed dynamic power-assisted to realize electric equilibrium after going out target zone.Therefore, originally
Invent while realizing SOC balance, the power current that mixed dynamic generating causes with mixed dynamic power-assisted can be prevented effectively from
The problem that battery life that the frequent discharge and recharge in pond causes reduces, and system effectiveness reduces the excessive fuel consumption caused and asks
