Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
A kind of new-energy automobile water-cooled cells heat management system as shown in Figure 1, comprise entire car controller 1, battery management system 2, electrokinetic cell 3, cooling water tank 4, radiator fan 5, circulating water pump 6, automatically controlled heating unit 7, the input of entire car controller 1 links to each other with battery management system 2, the output of entire car controller 1 respectively with radiator fan 5, circulating water pump 6 and automatically controlled heating unit 7 link to each other, radiator fan 5 is arranged on the sidepiece of cooling water tank 4, battery management system 2 is arranged on the inside of electrokinetic cell 3, cooling water tank 4, circulating water pump 6, link to each other by the water route successively between automatically controlled heating unit 7 and the electrokinetic cell 3, specifically, the delivery port of cooling water tank 4 links to each other with the water inlet of circulating water pump 6, the delivery port of circulating water pump 6 links to each other with the water inlet of automatically controlled heating unit 7, the delivery port of automatically controlled heating unit 7 links to each other with the water inlet of electrokinetic cell 3, and the delivery port of electrokinetic cell 3 links to each other with the water inlet of cooling water tank 4; Be connected by the CAN bus between entire car controller 1 and the battery management system 2.
The concrete course of work is as follows:
When electrokinetic cell 3 uses or charging, battery management system 2 is gathered electrokinetic cell 3 temperature inside information in real time and is transferred to the CAN bus, entire car controller 1 reads this temperature information in real time, when temperature is higher than first order high temperature threshold value, entire car controller 1 is opened by output port control circulating water pump 6, cooling water begins circulation, feed back according to temperature, if temperature begins to fall after rise, entire car controller 1 keeps circulating water pump 6 circulations, after making the temperature of electrokinetic cell 3 be reduced to the temperature of stable operation range, stop circulating water pump 6 work; If temperature continues to rise to when being higher than second level high temperature threshold value, entire car controller 1 control radiator fan 5 is opened, and strengthens the heat-sinking capability of water-cooling system, and the control of the temperature of electrokinetic cell 3 in the stable working range of electrokinetic cell, is closed radiator fan 5.
When temperature is lower than the low temperature threshold value, entire car controller 1 is opened by output port entire car controller circulating water pump 6, open automatically controlled heating unit 7 simultaneously, recirculated water plays heat effect to electrokinetic cell 3 inside this moment, rely on the structure of electrokinetic cell 3 inside and good water cycling hot conducting power, electrokinetic cell 3 internal temperatures can very fast rising, after electrokinetic cell 3 internal temperatures reach the stable working range temperature of electrokinetic cell, entire car controller 1 is closed automatically controlled heating unit 7, postpones to close circulating water pump 6 again after a period of time.
