Specific embodiment
For the utility model battery thermal management system is described in further detail, further illustrate with reference to the accompanying drawing, in figure
Dotted line indicates to be electrically connected between component, and arrow illustrates water (flow) direction in pipeline.
As shown in Figure 1, the battery thermal management system of the utility model, including it is entire car controller 9, heater 4, air-conditioning 2, dynamic
Power battery 8, engines tail hot-air heater 11, battery air intake passage 1, air-conditioning air-inducing passage 3, inlet valve 5, tube, heater inlet
6, heater outlet pipe 7, water pump 12；The heater 4 has adjustable revolving speed blower 14, radiator 15, air inlet hole 16；The sky
Adjusting 2 has air-conditioning evaporation fan 10, and the air-conditioning air-inducing passage 3 has air door 13；The air-conditioning 2 passes through air-conditioning air-inducing passage 3
Connect heater 4, heater 4 connects power battery 8 by battery air intake passage 1, the engines tail hot-air heater 11 with plus
The radiator 15 of hot device 4 is connected with tube, heater inlet 6, heater outlet pipe 7, the nearly radiator 15 of the tube, heater inlet 6
End is equipped with inlet valve 5, nearly 11 end of engines tail hot-air heater is equipped with water pump 12；The entire car controller 9 with can turn
Fast blower 14, air door 13, inlet valve 5, power battery 8, water pump 12, air-conditioning evaporation fan 10 are electrically connected.
Heating work: when vehicle is in the environmental work lower than 10 DEG C, entire car controller 9 is monitored inside power battery 8
Temperature, if 8 internal temperature of power battery is lower than 20 DEG C, entire car controller 9 is opened inlet valve 5 is controlled, then, full-vehicle control
Device 9 controls water pump 12 and starts to work, and the hot water of engines tail hot-air heater 11 will enter heater 4 by tube, heater inlet 6
Radiator 15 in, the air inlet 16 of the heated device 4 of air enters heater, and hot water flows through radiator 15 in heater 4
Air heating, then, hot water passes through heater outlet pipe 7 again and flows back to engines tail hot-air heater 11.Entire car controller 9 is controlled simultaneously
Adjustable revolving speed blower 14 starting inside heater 4 processed, and worked with maximum wind velocity, the warm wind generated in heater 4 will pass through
Battery air intake passage 1 enters power battery box 8, heats to it.When entire car controller 9 monitors inside power battery 8
When temperature is more than 40 DEG C, entire car controller 9 controls the closing of water pump 12 first, is delayed after 5S, and entire car controller 9 controls inlet valve
5 close, and the hot water of engines tail hot-air heater 11 does not enter back into heater 4 at this time.Meanwhile entire car controller 9 controls heater 4
Internal adjustable revolving speed blower 14 to minimum windspeed works, and the residual temperature inside heater 4 is dispelled, the adjustable work of revolving speed blower 14 1
It is closed after minute.With the reduction of 8 temperature of power battery, when temperature is down to 20 DEG C, Repeat-heating works again.
Air-conditioning heat dissipation work: when vehicle is in the environmental work higher than 30 DEG C, entire car controller 9 monitors power battery 8
Internal temperature, if temperature is higher than 40 DEG C, entire car controller 9 will control inlet valve 5, water pump 12 is in closed state.Then,
Entire car controller 9 is opened air-conditioning 2 is controlled, and is set 25 DEG C of air-conditioner temperature and is opened the work of air-conditioning evaporation fan 10, air-conditioning 2 starts
Refrigeration, entire car controller 9 open air conditioner damper 13, and the cold wind that air-conditioning 2 generates introduces heater 4 by air-conditioning air-inducing passage 3.Together
When entire car controller 9 control 4 internal adjustable revolving speed blower 14 of heater and worked with maximum wind velocity, adjustable revolving speed blower 14 is by cold wind
Power battery box 8 is entered by battery air intake passage 1, is radiated to it.When 8 internal temperature of power battery is lower than 28 DEG C
When, entire car controller 9 controls 4 internal adjustable revolving speed blower 14 of heater and stops working, and closes air conditioner damper 13.With temperature
Raising, when 8 temperature of power battery rises to 40 DEG C, again repeatedly air-conditioning heat dissipation work.
Natural wind heat dissipation work: when vehicle is in 15~25 DEG C of environment, battery system temperature is in convenient temperature
Degree, for energy conservation, entire car controller 9 can control air-conditioning 2 not work, inlet valve 5, water pump 12 are closed, the heat dissipation base of power battery 8
Originally the cold wind of air-conditioning 2, use environment wind are not needed.With coming into operation for power battery 8, temperature can continue to increase,
But since environment temperature is lower, ambient wind is entered inside heater 4 by 4 air inlet hole 16 of heater in compartment, then by adding
Adjustable revolving speed blower 14 is sent into battery air intake passage 1 in hot device 4, hence into power battery 8 is arrived, as wind regime, to battery
It radiates through row.When 8 internal temperature of power battery is lower than 20 DEG C, entire car controller 9 controls adjustable 14 wind of revolving speed blower of heater 4
Prompt drop is as low as minimum or stopping blower work.As the temperature rises, when 8 temperature of power battery rises to 40 DEG C, again to dynamic
The heat dissipation of power battery.
Power battery operating ambient temperature is larger to its aging effects, learns by long-term test and use experience, such as
Fruit guarantees temperature when battery works within the scope of 20 DEG C~45 DEG C, and service life, which can guarantee, reaches projected life.If not yet
There is good heat management system, will abuse because of battery causes battery life to fall sharply or have an accident.
