Whether the temperature in pond, fuel cell and in-car meets the 3rd set point, if meeting, i.e., when fuel cell is higher than fuel cell electricity
The design temperature of pond second and less than the design temperature of fuel cell the 3rd, electrokinetic cell higher than the design temperature of electrokinetic cell first and low
When the design temperature of electrokinetic cell second, vehicle interior temperature are less than in-car first design temperature, for example, the when electrokinetic cell the 3rd sets
Constant temperature degree is 60 DEG C, and the second design temperature of electrokinetic cell is 60 DEG C, the circulation that temperature control system passes through the second controllable threeway 4 of control
Partial circulating is closed in direction, and electrokinetic cell and fuel cell are no longer heated, now an opening vehicle interior circulation, is risen and is supplied for in-car
It is warm.
With the unlatching of in-car circulation, vehicle interior temperature constantly rises, and judges the temperature of electrokinetic cell, fuel cell and in-car
Whether degree meets the 4th set point, if meeting, i.e., when fuel cell is higher than the design temperature of fuel cell battery second and less than combustion
Expect the design temperature of battery the 3rd, electrokinetic cell higher than the design temperature of electrokinetic cell first and sets temperature less than electrokinetic cell second
Degree, when vehicle interior temperature is higher than in-car first design temperature and is less than in-car second design temperature, for example, in-car second design temperature
For 25 DEG C, temperature control system is by controlling outside the circulating direction opening vehicle outer circulation of the first controllable threeway 8, now in-car circulation and car
Circulate cooperation.Wherein, the unlatching of in-car circulation continues to heat for in-car, and car outer circulation is used for the auxiliary of fuel cell
Radiating.In addition, temperature control system can control the assignment of traffic of the second controllable threeway 4 according to in-car real time temperature, in-car circulation is realized
With the co-ordination of car outer circulation.
Raised with the continuation of vehicle interior temperature, judge whether electrokinetic cell, fuel cell and in-car temperature meet the
Five set points, if meeting, i.e., when fuel cell is set higher than the design temperature of fuel cell battery second and less than fuel cell the 3rd
Constant temperature degree, electrokinetic cell are higher than the design temperature of electrokinetic cell first and high less than the design temperature of electrokinetic cell second, vehicle interior temperature
When in-car second design temperature, temperature control system is by controlling the circulating direction of the first controllable threeway 8 to close in-car circulation, now
Opening vehicle outer circulation, the radiating for fuel cell.Certainly, in the case of only opening vehicle outer circulation, if fuel cell and
The temperature of electrokinetic cell continues to raise, and vehicle interior temperature is also remained on outside an opening vehicle when being higher than in-car second design temperature
Circulation.
In addition, the temperature management system also includes water quality detection instrument, the water quality detection instrument is positioned over water tank or water pump
Input, and by water quality early-warning information real-time Transmission to instrument board, when water quality detection value exceedes early warning value, instrument board report
It is alert, point out driver to change water.
It is pointed out that each setting of the fuel cell of temperature control system memory storage, electrokinetic cell and vehicle interior temperature
Temperature can be set according to user's request, it is not limited to the concrete numerical value provided in above-described embodiment.
