Description
The invention belongs to the electric power supply field of motor vehicle.
More accurately, the invention belongs to the field of the management of the power storage in motor vehicle, the trailer system of motor vehicle uses electric energy at least.These motor vehicles are for example electric car or hybrid vehicle.
In providing the field of electric energy for this motor vehicle, known electric chemical storage batteries and the use that is arranged on other electronic installation in car, storage battery allows to power to trailer system with electric power.Yet this battery pack has is providing the major defect of common performance aspect power capacity, memory space, useful life and cost.
In fact, electrochemical storage cell is that weak power all is provided in charging or in discharge, and has the limited time limit in useful life.Therefore, battery pack must be regularly replaced whole, the care and maintenance cost that this representative is relatively large.
In order to correct these shortcomings, imagined the coupling of different electric energy storage systems and used, for example be coupled to the electrochemical storage cell system of super capacitor system.
Here remember, ultracapacitor is to be implemented in order to for example allow to obtain middle power density between battery pack and traditional electrical electrolysis condenser and the capacitor of energy density.Therefore, these ultracapacitors have the power storage capacity higher than traditional capacitor, allow simultaneously this energy Ratios conventional batteries to recover quickly.
Therefore, these two kinds of systems have complementary feature, and one allows to provide high power but weak energy, and another allows to provide low-power but high-energy.
Usually, these two storage systems are connected by simple conductor betwixt, and unreal any method of distributing now electric energy between these two systems.In such coupling was installed, these two systems were connected in parallel usually betwixt, and were caused between system the exchange of natural energy at any time by the balance of voltage that the electricity law is forcibly stipulated.The distribution of the electric energy that therefore, obtains is for the operator scheme of car thereby for always not best in each energy demand constantly.In fact, main power supply system may occur and do not recharged fully, and car is in complete power mode of operation, needs simultaneously a large amount of electric energy in this mode process.Therefore the global energy storage system has medium-performance, especially aspect the availability of electric energy, thereby aspect the response time of Request System.
The object of the invention is to correct at least in part these shortcomings by the method that the power storage of management at least two storage device electrics is provided.More accurately, the object of the invention is to provide and allows effectively to distribute the method for electric energy between different memory devices, especially according to the feature of these equipment and the operator scheme of car.
Therefore, the present invention relates to manage the method for the power storage in storage system, this storage system comprises that the second equipment is intended for the circuit supply to motor vehicle by the first memory device of energy converter equipment connection and the second memory device.
The present invention is characterised in that, it comprises the following steps:
The parameter of the operator scheme of-definite expression car,
-determine the charging target of the second equipment according to the operator scheme of car, and
-control energy converter, in order to permit the Energy Transfer from one of described equipment to another, thereby reach the charged state of the second memory device and this charged state is maintained the charging target level.
Note, in whole specification, term " Energy Transfer " and " energy exchange " have identical implication.
In favourable execution mode of the present invention, the method also comprises the state parameter of the state of also determining to represent memory device except the parameter of operator scheme of expression car and by providing the control signal that depends on these parameters to control the step of transducer.
According to execution mode, in the group that the state parameter of memory device is listd under being included in and comprising: the electric charge of equipment, in the operating temperature of the voltage at this device end place, this equipment and connecting devices to electric power converter or the value of electric current that the second equipment connection is flowed in the capacitor of power supply circuits.
Power supply circuits just itself comprise the trailer system of car, and may comprise in some embodiments especially and to allow to being arranged on different electric power in car and/or any other secondary circuit of electronic installation or consumer power supply.
According to the operator scheme of car, trailer system utilizes electric energy or produces on the contrary electric energy.In fact, the operating principle of hybrid vehicle for example is, for example has in the stage of running at high speed of a small amount of acceleration and deceleration in some travel phase, and trailer system is by the Thermal Motor power supply that produces electric energy.Aspect of the present invention realization the in such car, in the decelerating phase process, can predict and again obtain the possibility that electric energy that Thermal Motor produces is used for following use.In this case, must store when needed the energy that produces, it is useful therefore maintaining the second memory device in the state that seldom charges, in order to allow again to obtain and store a large amount of electric energy that produce.
On the contrary, when hybrid vehicle was in pure power mode of operation, trailer system did not produce any electric energy, therefore needn't stay free memory space in the second energy storage device.
Therefore it seems during the energy exchange of controlling between two memory devices, must consider the operator scheme of car.Carry out this consideration by the charging target of fixing the second equipment, this charging target depends on operator scheme, as previously mentioned.
According to execution mode, the parameter of the mode of operation of expression car can have different types:
-it may relate to engine parameter, engine speed for example,
-it may relate to electrical quantity, for example prediction of the operator scheme of the electric power system of car or upcoming energy request,
-it may relate under the car parameter of combination results of two or more elements lising: engine parameter, travel restriction and user command; The example of car parameter is the speed of a motor vehicle.
According to driving conditions for example determine in one embodiment by city pattern and city external schema for the operator scheme of car.In another embodiment, it is determined according to for example feature of full electric power or hybrid vehicle.
In addition, in one embodiment, the method comprises the state parameter of the state of also determining to represent memory device except the parameter of the operator scheme of determining the expression car and by providing the control signal that depends on these parameters to control the step of transducer.
The charging target is determined, in order to guarantee that the needs of the consumption of electric power system of the charge or discharge leeway of the second memory device and car or generation are compatible.
In fact, the operating principle of hybrid vehicle for example is, in the time of in car is at a high speed and has the travel phase of weak variation, general route on highway, the trailer system of car produces electric energy.During the decelerating phase, prediction regains the possibility that the electric energy that is produced by Thermal Motor is used for following use.Therefore, under such travel situations, it is useful that the second memory device that is connected to trailer system is not in the state that is full of electric charge, in order to can store gradually the energy that produces.
Therefore, in order to consider these restrictions, in one embodiment, the charging target is determined with following method:
-when car operated according to the city pattern, the charging target was fixed to maximum charge only about half of of the second equipment, accelerate during the pattern of described city and slow down frequent,
-when car is in pure power mode of operation, the charging target be fixed to the second equipment maximum charge 100%, and
-when car according to the city outside during operation mode, the charging target is fixed to 0, during operator scheme the relatively high and variation of speed is seldom described city outside.
In favourable realization of the present invention, under the pattern of city, the charging target be fixed to be included in maximum charge 45% and 55% between value.
In more favourable realization, the charging target be fixed to the second memory device maximum charge be included between 49% and 51%, generally be 50% value.
Yet the power converter that uses during realizing the method according to this invention has limited maximum power, and it depends on the type of transducer.Therefore, in some embodiments, may the second memory device reach 0% charge level and the target of charging is not fixed to this value.Such situation especially produces during higher than the available flow of transducer at the electric energy flow that is provided to trailer system by the second memory device.
In an identical manner, may the second memory device reach 100% charge level, for example when the operational circumstances of car be that for example electric energy produces too soon or when too many.
Such situation that electric charge is full of or all exhausts also can occur the first memory device.In all these situations, these extreme situations must adapt to the operator scheme of car, in order to avoid bad operation or fault.
For this reason, in one embodiment, the method comprises the following steps:
-determine the charged state of the first memory device and/or the second memory device,
If-this state is the state that electric charge is full of or all exhausts, or very near the state of one of these states, notification message is sent to the one or more electronic computers that are arranged in car.
Therefore, in a kind of configuration, when the charge level one of memory device surpass its maximum charge 95% or lower than 5%, just notification message is sent to the one or more electronic computers that are arranged in car.
The result of the state that electric charge is full of or all exhausts relates to the first memory device or the state of the second memory device according to it and is slightly different.
In fact, be in one of these extreme situations if be directly connected to the second memory device of power supply circuits, result is the unavailability of storage system integral body, no matter in order to provide electric energy still in order to receive it.Therefore must notify whole computers and car other electronic installation they can not recycle or provide electric energy during certain period.
On the contrary, if it relates to the first equipment, result the operation of car is hindered less because this equipment and be not used in directly any device power supply to car, but be used for and the second devices exchange energy uniquely, in order to distribute in the best way electric energy between these two equipment.
In this case, this situation of different computers that still must the notice car is so that the increase of avoiding having demand or generation as a result of thereby cause any operation of the situation that the electric charge of the second equipment is full of or all exhausts.
