Description
The invention belongs to the supply of electrical energy field of motor vehicle.
More accurately, the invention belongs to the field of the management of the power storage in the motor vehicle, the trailer system of motor vehicle uses electric energy at least.These motor vehicles are for example electric car or hybrid vehicle.
Providing for this motor vehicle in the field of electric energy, known electric chemical storage batteries and the use that is installed in other electronic installation in the car, storage battery allows to power to trailer system with electric power.Yet this battery pack has at the major defect that common performance is provided aspect power capacity, memory space, useful life and the 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, must regularly replace battery pack integral body, the care and maintenance cost that this representative is big relatively.
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 ultracapacitor system.
Remember that here ultracapacitor is to be implemented so that for example allow to obtain the 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 that is higher than traditional capacitor, allow this energy to recover quickly than conventional batteries simultaneously.
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 are not implemented in any method of distributing 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.Therefore, the distribution of the electric energy that is obtained is for the operator scheme of car thereby for always best in each energy demand constantly.In fact, main electric power system may occur and do not recharged fully, and car is in the complete power mode of operation, needs a large amount of electric energy in this mode process simultaneously.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 these shortcomings at least in part 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 permission to distribute the method for electric energy effectively 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 first memory device and second memory device that is connected by energy converter equipment, and second equipment is intended for the circuit supply to motor vehicle.
The present invention is characterised in that it may further comprise the steps:
The parameter of the operator scheme of-definite expression car,
-determine the charging target of second equipment according to the operator scheme of car, and
-control energy transducer, so that the power transfer of allowance from one of described equipment to another, thereby reach the charged state of second memory device and this charged state is maintained the charging target level.
Notice that in whole specification, term " power transfer " has identical implication with " energy exchange ".
In favourable execution mode of the present invention, this method also comprises the state parameter of the state of also determining the expression memory device except the parameter of the operator scheme of expression car and depends on the step that these parameter control signals come the control transformation device by providing.
According to execution mode, the state parameter of memory device is included in and comprises in the group of lising down: 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 second equipment is being connected to the value of the electric current that flows 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 give the different electric power that is installed in the 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 electric energy on the contrary.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 the realization of the present invention in such car, in the decelerating phase process, can predict the possibility that the electric energy that obtains Thermal Motor again and produced is used for following use.In this case, must store the energy that is produced when needed, it is useful therefore maintaining second memory device in the state that seldom charges, so that allow to obtain again and store a large amount of electric energy that produced.
On the contrary, when hybrid vehicle was in the pure power mode of operation, trailer system did not produce any electric energy, therefore needn't stay free memory space in 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 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 to the car parameter of the combination results of the two or more elements from list down: 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, this method comprises the state parameter of the state of also determining the expression memory device except the parameter of the operator scheme of determining the expression car and depends on the step that these parameter control signals come the control transformation device by providing.
The charging target is determined, so that guarantee that the needs of the consumption of electric power system of the charge or discharge leeway of second memory device and car or generation are compatible.
In fact, the operating principle of hybrid vehicle for example is, when car was at a high speed and has in the travel phase of weak variation, the general route on highway, the trailer system of car produced 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 second memory device that is connected to trailer system is not in the state that is full of electric charge, so that can store the energy that is produced gradually.
Therefore, in order to consider these restrictions, in one embodiment, the charging target is determined with following method:
-when car was operated according to the city pattern, the charging target was fixed to maximum charge only about half of of second equipment, during the pattern of described city, quicken and slow down frequent,
-when car is in the pure power mode of operation, the charging target be fixed to second equipment maximum charge 100%, and
-when car according to the city outside during operation mode, the charging target is fixed to 0, the high relatively and variation of speed is seldom during the operator scheme 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 second memory device maximum charge be included between 49% and 51%, generally be 50% value.
Yet, realizing that the power converter that uses during the method according to this invention has limited maximum power, it depends on the type of transducer.Therefore, in some embodiments, may second memory device reach 0% charge level and the target of charging is not fixed to this value.Such situation especially produces when the electric energy flow that is provided to trailer system by second memory device is higher than the available flow of transducer.
In an identical manner, may reach 100% charge level by second memory device, for example the operational circumstances when car is when for example electric energy produces too fast or too much.
Such situation that electric charge is full of or all exhausts also can occur first memory device.Under all these situations, these extreme situations must adapt to the operator scheme of car, so that avoid bad operation or fault.
For this reason, in one embodiment, this method comprises the following steps:
-determine the charged state of first memory device and/or second memory device,
If-this state is the state that electric charge is full of or all exhausts, or, then notification message is sent to the one or more electronic computers that are installed in the car very near the state of one of these states.
Therefore, in a kind of configuration, when the charge level one of memory device surpass its maximum charge 95% or be lower than 5%, just notification message is sent to the one or more electronic computers that are installed in the car.
The result of the state that electric charge is full of or all exhausts relates to state that first memory device still is second memory device according to it and is slightly different.
In fact, be in one of these extreme situations if be directly connected to second memory device of power supply circuits, then the 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 during certain period, can not utilize or provide electric energy again.
On the contrary, if it relates to first equipment, then the result operation of car is hindered less because this equipment and be not used in any device power supply of directly giving car, but be used for uniquely and the second devices exchange energy, so that between these two equipment, distribute electric energy in the best way.
In this case, this situation of various computing machine 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 second equipment is full of or all exhausts.
