For above-mentioned purpose of the present invention, feature and advantage are become apparent more, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.It should be noted that, the each structure in accompanying drawing is schematic instead of determinate, so that those of ordinary skill in the art understand principle of the present invention best, it is not necessarily drawn in proportion.
Fig. 1 shows the example Vehicular battery cooling system that is applicable to method provided by the present invention.As shown in Fig. 1 right side, the applicable electric automobile of the present invention battery cooling system can comprise substantially battery 08, coolant pump 09, cooling fluid pipeline 12, battery cooler 04, the first expansion valve 06 and motor compressor 01, wherein motor compressor 01 is equally also used to the air-conditioning system into automobile cabin refrigeration.The air-conditioning system that shows electric automobile in Fig. 1 left side, mainly comprises: motor compressor 01, condenser 02, evaporator 03, the second expansion valve 05, refrigeration pipe 07.In addition, for putting into practice method provided by the present invention, cooling-water temperature transmitter 10 and battery temperature sensor 11 temperature with Real-Time Monitoring cooling fluid and battery is set on can the appropriate position in battery cooling system.As can be seen from Fig. 1, cooling-water temperature transmitter 10 is arranged for the coolant temperature T that reads battery 08 porch
cooling fluid.
Those skilled in the art will appreciate that method provided by the present invention goes for any to similar shown in Fig. 1 batteries of electric automobile cooling system.In addition, in this system, related any part can adopt any existingly maybe method being developed or device are realized in this area.The selection of cooling fluid also can be determined according to actual needs, for example water, water/ethylene glycol mixture etc.
Figure 2 illustrates the flow chart of Vehicular battery method for controlling cooling system according to an embodiment of the invention.In practice, the control strategy of battery cooling system can be integrated in air-conditioner controller.Air-conditioner controller can with intrasystem various sensor communications, and according to collected battery temperature T
battery, coolant temperature T
cooling fluid, motor compressor signal, liquid cooled electronics pump signal, the first expansion valve switching signal, passenger compartment refrigeration demand signal etc. control the execution of method provided by the present invention.
As shown in Fig. 2 left side, when battery temperature is greater than the first temperature threshold T
1shi Caiyong the first refrigerating mode, this first refrigerating mode can be lowered the temperature taking the cooling fluid by Current Temperatures as battery for being set as starting coolant pump.T
1can be selected as the median of the optimum working temperature scope of battery.In other embodiment, T
1can also be selected as particularly as required+1 DEG C or-1 DEG C.In conventional battery cooling procedure, start motor compressor simultaneously and provide cold-producing medium to make cooling fluid cooling to produce liquid circulation, also can give tacit consent to except starting coolant pump.Under the first refrigerating mode, only prevent battery temperature further to raise with existing coolant temperature level in cooling fluid pipeline.In this case, the temperature of battery is conventionally still in acceptable level, and not needing to start immediately motor compressor provides cold-producing medium to carry out the cooling procedure that intensity is larger.Because the cooling fluid in cooling fluid pipeline can keep the temperature levels lower with respect to battery conventionally, thereby be enough to help battery temperature to be controlled in scope of design in the situation that of the normal operation of automobile.Coolant pump and motor compressor are separated and control the operating time that can effectively reduce compressor, reduce battery power consumption.
In the situation that keeping the first refrigerating mode operation, when detecting that battery temperature reduces gradually, for example, lower than the 4th temperature threshold T
4time, can close coolant pump with the whole battery cooling system of temporarily stopping using, and ought again detect that battery temperature is greater than above-mentioned the first temperature threshold T
1time, start to reactivate battery cooling system from first mode.Preferably, T
4can be 0 DEG C ~ 2 DEG C of the higher limit of battery optimum working temperature or the higher limits that is greater than described battery optimum working temperature.
On the other hand, in the situation that keeping the first refrigerating mode operation, when detecting that battery temperature is greater than the second temperature threshold T
2time can start the second refrigerating mode, as shown in the right side in Fig. 2.According to method provided by the present invention, the second temperature threshold T
2whether determine in quick-charge state according to battery.Because battery fill soon with non-while filling soon caloric value have relatively big difference, so judge that by different standards whether battery needs to start motor compressor cooling is favourable.Preferably, at battery in quick-charge state in the situation that, T
2can be confirmed as the higher limit of battery optimum working temperature, and at battery not in quick-charge state in the situation that, T
2can be confirmed as being greater than 1 ~ 3 DEG C of the higher limit of battery optimum working temperature.
Enter the second refrigerating mode and show that battery temperature continues to raise, only by the circulation of cooling fluid self, to cooling fluid, cooling cannot not make battery temperature reduce.Thereby, in this second refrigerating mode, first start by motor compressor and provide cold-producing medium to reduce the first process of coolant temperature to battery cooler, and start the precondition of motor compressor, i.e. the startup of coolant pump completes in the first refrigerating mode.As shown in Figure 2, the first process can comprise the following operation of execution in order: 1) open the first expansion valve 06; 2) judge whether passenger cabin also needs refrigeration simultaneously.The open and close of two expansion valves and the rotational speed regulation of motor compressor come in control chart 1 in conjunction with the refrigeration demand of passenger cabin are preferred.
Particularly, in the first process, if passenger cabin has refrigeration demand, need the rotating speed that increases motor compressor to meet the refrigeration demand of air-conditioning system and battery cooling system simultaneously.If passenger cabin does not have refrigeration demand, only need to start motor compressor with the desired normal speed of battery cooling system.
Further, this second refrigerating mode is also included in the situation that meets certain condition and carries out and make motor compressor suspend the second process that cold-producing medium is provided to battery cooler.As shown in Fig. 2 right side, this second process comprises carries out following operation in order: 1) judge whether passenger cabin needs refrigeration; 2), in the situation that passenger cabin need to freeze, first close the first expansion valve 06, then reduce the rotating speed of motor compressor; In the situation that passenger cabin does not need refrigeration, first close motor compressor, after waiting for a period of time, close again the first expansion valve.In practice, waiting time t can determine according to the shutdown speed of motor compressor self, and for example t=(the current rotating speed/compressor shutdown of compressor speed)+0.5 can effectively prevent the impact that the effect of inertia of compressor causes system thus.For instance, if the current rotating speed of compressor is 6000 revolutions per seconds, shutting down speed is 2000 revolutions per seconds, closes motor compressor stand-by period t=(6000/2000)+0.5=3.5 second afterwards.
In practice, no matter be adopt the first refrigerating mode or adopt the second refrigerating mode, no matter be to carry out the first process or second process of execution under the second refrigerating mode, control system is all by the temperature of monitoring battery always.After completing the first process, battery cooling system will keep motor compressor refrigeration (not shown in Figure 2) within a period of time, if battery temperature is detected and is less than the 3rd temperature threshold T during this period
3time, battery cooling system will be controlled as and return to above-mentioned the first refrigerating mode.In practice, return to the first refrigerating mode and can comprise once above-mentioned the second process (not shown in Figure 2) of execution, first make motor compressor battery cooling system not worked (close or reduce rotating speed), and then keep only preventing that with the circulation of Current Temperatures battery temperature from rising by cooling fluid.Preferably, the 3rd temperature threshold T
3it can be the temperature value that is less than 1 DEG C ~ 3 DEG C of the higher limits of battery optimum working temperature.
On the other hand, under the second refrigerating mode, when battery temperature is all the time higher than the 3rd temperature threshold T
3time, the operation that preferably can switch battery cooling system between above-mentioned the first and second processes according to coolant temperature, also control operating time of motor compressor.For example, can be less than coolant temperature lower limit T in coolant temperature
lshi Zhihang the first process; And be greater than coolant temperature upper limit T in coolant temperature
hshi Zhihang the second process.In some embodiments of the invention, coolant temperature lower limit can be set to the lower limit that makes motor compressor stop providing to battery cooler cold-producing medium, and the coolant temperature upper limit can be set to the higher limit that makes motor compressor that cold-producing medium is provided to battery cooler.Thus, even under the second refrigerating mode, motor compressor can not keep running status for a long time yet, and on the contrary, the circulating cooling ability of cooling fluid self is fully used.
First the present invention has realized separately controlling coolant pump and motor compressor in the battery cooling system of electric automobile.On the other hand, the present invention has considered and the matching problem of automotive air-conditioning system in the battery cooling system control strategy of electric automobile.In the time that wherein a road need to open or close, for avoiding impacting for another road produces, the solution of the present invention provides the flexible manipulation to motor compressor rotating speed.Thus, the present invention can effectively reduce the operating time of motor compressor, reduces battery power consumption, increases the course continuation mileage of automobile.
