Electrical power is contrasted with the first restrictive condition and the second restrictive condition, when meeting restrictive condition, obtains power compensating value, root
The driving power and generated output of power drive system are controlled according to the power compensating value, in electrokinetic cell electric discharge, charging
During, aforesaid operations can be repeated in real time, until causing the actual discharge of electrokinetic cell, charge power to fall within conjunction
It within the power bracket of reason, can effectively extend the service life of electrokinetic cell, improve vehicle performance.
It is understandable to enable the above objects, features and advantages of the present invention to become apparent, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
In the present embodiment, illustrated so that the power drive system is hybrid power system as an example.The electric drive trains
System includes entire car controller (VCU, Vehicle ControlUnit), by electrokinetic cell that is multiple monomer series-connected or composing in parallel
And battery management system (BMS, Battery Management System), motor (TM, T-Motor), startup generating one
Body motor (ISG, Integrated Started Generator), engine, high-tension electricity air-conditioning and DC-to-dc converter
(DC-DC inverter).Electrokinetic cell, TM, ISG, high-tension electricity air-conditioning and DC-DC inverter are in same HVDC
On bus, the VCU in power drive system receives the various information from BMS, TM, ISG simultaneously, and sends main contactor to BMS
Open-close instruction, to the limitation of TM, ISG maximum drive torque and maximum generation torque limit, peak power is sent to high-tension electricity air-conditioning
Limitation, and operating voltage set point is sent to determine its power output to DC-DC inverter.
With reference to power drive system as described above, the Poewr control method of the present invention is described.In the present embodiment,
Specifically illustrated by taking the control to the discharge power of electrokinetic cell as an example.
Fig. 2 is the schematic flow sheet of the Poewr control method for the power drive system that the present embodiment provides.
Step S201 is performed, obtains the first limits value and the second limits value.
First limits value is the maximum discharge power of electrokinetic cell, and first limits value can pass through full-vehicle control
Device VCU is obtained according to the information from power battery management system BMS received.
Second limits value is obtained according to first limits value.
Specifically, second limits value can be obtained by formula (1).
P2=Kmd × P1 (1)
Wherein, P1 is first limits value, and P2 is second limits value, and Kmd is proportionality coefficient.
Kmd is the proportionality coefficient less than 1, and the Kmd can test according to electrokinetic cell and the result of vehicle test passes through
Demarcation obtains, can be with reference to the state-of-charge of the electrokinetic cell, the coolant temperature of electrokinetic cell, electrokinetic cell monomer most
The maximum discharge power of high-temperature, the minimum temperature of electrokinetic cell monomer and electrokinetic cell is determined to the Kmd.
After the first limits value and the second limits value is obtained, the actual power of current power battery and first can be limited
Whether value, the second limitation are analyzed, to determine the actual power of electrokinetic cell within rational power bracket.
Step S202 is performed, judges whether the discharge power of electrokinetic cell meets the first restrictive condition.
The discharge power of first restrictive condition including the electrokinetic cell is more than first limits value and described dynamic
The discharge power of power battery meets at least one of (P1-P2) ＜ Pd≤P1 conditions situation, wherein, Pd is electrokinetic cell
Actual discharge power.
First limits value is it can be appreciated that be the hard limitation of electrokinetic cell electric discharge, in the reality of the electrokinetic cell
When discharge power Pd exceedes first limits value, that is, when exceeding the hard limitation of electric discharge, it is determined that meeting the first restrictive condition.It is logical
Often, the discharge power of the electrokinetic cell be on the occasion of.
In order to preferably can effectively be protected to the discharge power of electrokinetic cell, the second limits value can be combined and set
First restrictive condition.
Second limits value can be understood as the soft limitation of electrokinetic cell electric discharge, in the electric discharge work(of the electrokinetic cell
When rate meets (P1-P2) ＜ Pd≤P1, the soft limitation referred to as more than electrokinetic cell electric discharge, it can also now be defined as satisfaction the
One restrictive condition.
It is stepped up with the discharge power of electrokinetic cell, it is possible that exceed soft limitation as described above first,
I.e. the discharge power of electrokinetic cell meets (P1-P2) ＜ Pd≤P1, as the discharge power of electrokinetic cell continues to increase, can surpass
The hard limitation of electrokinetic cell electric discharge is crossed, i.e. the discharge power of electrokinetic cell meets Pd ＞ P1, in this case, still determines power
The discharge power of battery meets the first restrictive condition.
If step S202 judged results are "Yes", step S203 is performed；Otherwise return and perform step S201, according to power electric
The current electric discharge operating mode in pond determines corresponding first limits value and the second limits value, and then to the actual discharge of follow-up driving force battery
Power is analyzed.
Step S203 is performed, obtains the first overflow value and the second overflow value.
The actual discharge power of electrokinetic cell is analyzed beyond the degree of the first limits value and/or the second limits value.
When the discharge power of the electrokinetic cell is more than first limits value, obtains first by formula (2) and overflow
It is worth Δ P1.
Δ P1=Pd-P1 (2)
When the discharge power of the electrokinetic cell meets (P1-P2) ＜ Pd≤P1, obtain second by formula (3) and overflow
Go out to be worth Δ P2.
Δ P2=Pd-P1+P2 (3)
If the actual discharge power of current power battery has only exceeded soft limitation, that is, when meeting (P1-P2) ＜ Pd≤P1,
The power compensating value of power drive system can be obtained according to second overflow value, if the actual discharge power of current power battery
Hard limitation is have also exceeded, then the power back-off of power drive system can be obtained in combination with the first overflow value and the second overflow value
Value.
For the ease of the subsequently calculating to power compensating value, corresponding flag bit can be set, such as in the power electric
When the discharge power in pond is more than first limits value, set is carried out to the first flag bit, when being unsatisfactory for this condition to described
First flag bit resets.
When the discharge power of the electrokinetic cell meets (P1-P2) ＜ Pd≤P1, set is carried out to the second flag bit,
Second flag bit is resetted when being unsatisfactory for this condition.
The condition met by the flag bit can to the electrokinetic cell clearly makes a distinction.
Step S204 is performed, the work(of the discharge power of corresponding electrokinetic cell is obtained according to the first overflow value and the second overflow value
Rate offset.
The power compensating value of the power drive system can be obtained by formula (4).
Ppnlty=(K1 × Δ P1+K2 × ∫ (Δ P1 × dt)) × A1+ (K3 × Δ P2+
K4×∫(ΔP2×dt))×A2+(K5×ΔP3+K6×∫(ΔP3×dt)) (4)
×A3+(K7×ΔP4+K8×∫(ΔP4×dt))×A4

P2) ＜ Pd≤P1 flag bit, A3 are that the charge power of the electrokinetic cell is more than the flag bit of the 3rd limits value, and A4 is
The charge power of the electrokinetic cell meets (P3-P4) ＜ Pc≤P3 flag bit.
K1~the K8 can be determined accordingly according to the experimental data and vehicle test data of electrokinetic cell, its
In, P3 and P4 are required the 3rd limits value used and the 4th limitation when the charge power to electrokinetic cell is analyzed
Value, A3 and A4 are respectively the flag that the condition met to the charge power of electrokinetic cell enters line flag.On electrokinetic cell
Charge power related content can describe in detail in other embodiments, herein first be not specifically described.
During electrokinetic cell discharges, the flag that the charging of corresponding electrokinetic cell is related should be resetted,
That is in formula (4), the value that A3 and A4 value can be understood as 0, A1 and A2 is 1, then for the work(of power drive system
