See also Fig. 1, schematically demonstrated the basic composition of Vehicular dynamic battery group thermostatic control system of the present utility model in the figure.
This Vehicular dynamic battery group thermostatic control system is installed on the vehicle, and it is to comprise adding thermal sub-system 1 and cooling subsystem 2 these two parts in general.Wherein, adding thermal sub-system 1 is to be communicated with the mode of Vehicular dynamic battery group 3 with heat exchange, so that come Vehicular dynamic battery group 3 is carried out heat treated by being contained in the heat transferring medium that adds in the thermal sub-system 1 when needed by the user.And cooling subsystem 2 also is to be communicated with the mode of Vehicular dynamic battery group 3 with heat exchange, so that come Vehicular dynamic battery group 3 is carried out cooling processing by the cold-producing medium 24 in the cooling subsystem 2 when needed by the user.
Be specifically described below in conjunction with a preferred embodiment, so that more be expressly understood the above-mentioned structure and the characteristics thereof that add thermal sub-system 1 and cooling subsystem 2 at this Vehicular dynamic battery group thermostatic control system shown in Fig. 1.
As shown in Figure 1, in this preferred embodiment, add thermal sub-system 1 and comprise closed circulation pipeline 11, heat producer 12, pump 13, first break valve 14 and first heat exchanger 15.Particularly, in closed circulation pipeline 11, heat transferring medium is housed (for example, any existing appropriate medium such as water), above-mentioned heat producer 12, pump 13, first break valve 14 and first heat exchanger 15 then are installed in this closed circulation pipeline 11 successively by as shown in Figure 1 the flow direction along heat transferring medium 16.Wherein, heat producer 12 is to be provided for producing heat to come heat exchanging medium 16 to heat with this, for example can adopt electric heater commonly used in the prior art to be realized; Pump 13 is to be installed in closed circulation pipeline 11 to be used for heat transferring medium 16 after the pumping heating; First break valve 14 is to be used to flow in closed circulation pipeline 11 by heat transferring medium 16 when needed; First heat exchanger 15 is provided for carrying out heat exchange with Vehicular dynamic battery group 3.
See also Fig. 1 again, in above-mentioned preferred embodiment, cooling subsystem 2 comprises refrigerant line 21, second break valve 22 and second heat exchanger 23.Wherein, refrigerant line 21 is set to be connected to the on-board air conditioner system so that the refrigerating function that utilizes the latter easily and possessed, and second break valve 22 is installed in the refrigerant line 21 is to be used for ending when needed cold-producing medium 24 flowing in refrigerant line 21, and 23 on second heat exchanger is to be set to be used in the refrigerant line 21 carrying out heat exchange with Vehicular dynamic battery group 3.
Under preferred situation, can also as illustrated in fig. 1 second heat exchanger 23 be arranged on first heat exchanger, 15 inside with more convenient, realize that heat exchange controls the temperature of Vehicular dynamic battery group 3 neatly.In addition, can adopt electric check valve of the prior art for first break valve 14 and second break valve 22.
To further specify at the above-mentioned concrete composition structure that adds thermal sub-system 1 and cooling subsystem 2 below and how use this Vehicular dynamic battery group thermostatic control system to realize control as required Vehicular dynamic battery group 3.
When needs heat Vehicular dynamic battery group 3, heat producer 12 is started working produce heat, and make first break valve 14 also be in opening, open simultaneously that pump 13 is crossed first heat exchanger 15, Vehicular dynamic battery group 3 with heat transferring medium 16 pump flow and in closed circulation pipeline 11 in the figure direction as shown of arrow A circulate.Like this, just constantly brought into Vehicular dynamic battery group 3 by the heat that heat producer 12 generated and carry out heat exchange with it by heat transferring medium 16, thereby make the temperature of power battery pack 3 constantly raise, so promptly realized the purpose that this power battery pack is heated.Should keep second break valve 22 to be in closed condition in above operating process, the cold-producing medium in the on-board air conditioner system also carries out heat exchange with regard to not flowing into second heat exchanger 23 like this.
When needs cool off Vehicular dynamic battery group 3, should make heat producer 12 be in closed condition and do not produce heat.Simultaneously, opening the on-board air conditioner system freezes, and with 22 unlatchings of second break valve, cold-producing medium 24 will advance through refrigerant line 21 and evaporation in first heat exchanger 15 along the direction as shown of arrow B among the figure and C thus, owing to the heat that has absorbed heat transferring medium 16 in first heat exchanger 15 makes the temperature of heat transferring medium 16 be lowered.At this moment, first break valve 14 and pump 13 also are set up and remain on opening, so that the heat transferring medium 16 after the cooling flows through first heat exchanger 15, Vehicular dynamic battery group 3 and circulates in closed circulation pipeline 11.In aforesaid process, the heat transferring medium 16 after the cooling will constantly be taken away its heat through Vehicular dynamic battery group 3, thereby its temperature is constantly descended to realize that it is carried out cooling purpose.
When Vehicular dynamic battery group 3 is in suitable following time of working temperature environment, then second break valve 22, first break valve 14 etc. can be closed and needn't carry out above-mentioned heating or cooling down operation, reduce consumption with this, improve the continuation of the journey mileage of vehicle the vehicle energy.
Need be pointed out that again that (not shown) in preferred embodiment more can also adopt hyundai electronics and control technology further to optimize function of the present utility model, to realize automatic constant-temperature control to the Vehicular dynamic battery group.
Particularly, can set up temperature detecting unit and these two parts of control unit at Vehicular dynamic battery group thermostatic control system.Wherein, temperature detecting unit is to be set in the power battery pack 3 to be used for carrying out temperature detection; control unit then is to be set up all and above-mentioned temperature detecting unit; and the aforesaid thermal sub-system 1 that adds keeps being connected with cooling subsystem 2; thereby can be to comparing by detected temperature value of temperature detecting unit and default temperature objectives controlling value at Vehicular dynamic battery group 3; automatically control the unlatching that adds thermal sub-system 1 or cooling subsystem 2 or close (heating or the cooling processing of promptly coming Vehicular dynamic battery group 3 is carried out protectiveness) with this, realize the automatic constant-temperature control of power battery pack with this according to predefined logic.Certainly, above-mentioned temperature detecting unit can adopt existing temperature sensor to realize.Under preferred situation, control unit can be arranged among electronic control unit ECU or the power train control module PCM, and the temperature objectives controlling value of Vehicular dynamic battery group 3 also is stored among electronic control unit ECU or the power train control module PCM.Certainly, also allow to set up according to actual needs the function that independent control assembly removes to realize above-mentioned control unit, and the temperature objectives controlling value of Vehicular dynamic battery group 3 can be arranged in this control assembly.
More than enumerate some specific embodiments and come sets forth in detail Vehicular dynamic battery group of the present utility model thermostatic control system, these a few examples are only for the usefulness that principle of the present utility model and execution mode thereof are described, but not to restriction of the present utility model, under the situation that does not break away from spirit and scope of the present utility model, those of ordinary skill in the art can also make various distortion and improvement.Therefore, all technical schemes that are equal to all should belong to category of the present utility model and be limited by every claim of the present utility model.
