Water pump 10 works, to realize the effect of Water-cooling circulating cooling, so as to ensure that electric motor and controller circuit is run at a normal temperature.
Here whole cooling system controls whether work by control unit 15, and control unit 15 can be car body controller or single-chip microcomputer
Etc. the control chip for possessing data processing and control.
A kind of control method of electric car temperature control system, comprises the following steps：
Gather the temperature data of electrokinetic cell；The temperature data of electrokinetic cell is gathered by the first temperature sensor 13；
Judge whether temperature of powered cell is more than the first threshold temperature；The first temperature valve is preset in control unit 15
Value, the data transmitted according to the first temperature sensor 13, which are compared, to be judged whether to be more than the first threshold temperature；
If being more than the first threshold temperature, electrokinetic cell is cooled, the first electric water pump 3 is opened, now controls first
The first interface of triple valve 5, second interface are opened, and the 3rd interface is closed, and control unit 15 controls the first of the second triple valve 6 to connect
Mouth, second interface are opened, and the 3rd interface is closed；I.e. control single 15 sends control signal respectively to the first triple valve, the second threeway
Valve is to control corresponding interface to open and close.
Judge whether the temperature of electrokinetic cell is less than second temperature threshold values；
If being less than second temperature threshold values, electrokinetic cell is heated, opens the first electric water pump 3, control PTC heaters 4 open
Start building to make, control the first triple valve 5 first interface, the 3rd interface are opened, and the second interface of the second triple valve 6, the 3rd interface are beaten
Open, the second interface of the first triple valve 5 is closed, and the first interface of the second triple valve 6 is closed.I.e. control single 15 sends control signal
Respectively to the first triple valve 5, the second triple valve 6 to control corresponding interface to open and close.
When temperature of powered cell is more than the first threshold temperature, judge whether temperature data is more than the 3rd threshold temperature, if
It is to open air conditioning for automobiles, motor compressor 8 works, and air conditioning for automobiles coolant transmission to cooler 1 is cold by air conditioning for automobiles refrigerant
But the liquid of the first liquid cooling system 2 output.First liquid cooling system 2 of so electrokinetic cell is exported to the liquid in cooler 1 just
The cooling of liquid can be accelerated by air conditioning for automobiles refrigerant.
Wherein the 3rd threshold temperature is more than the first threshold temperature, and the first threshold temperature is more than second temperature threshold values.Here
The setting of threshold temperature can be set according to electrokinetic cell operating temperature standard.Operating temperature standard when being dispatched from the factory according to battery is set
Subzero 10 degree when calmly, such as the minimum operating temperature of battery, temperature is low again may to influence battery work, then second temperature threshold values is
2 °, when reaching this temperature, start ptc heater 4 and the opening and closing of corresponding triple valve, to realize heated power battery.In cooling,
Electrokinetic cell standard operating temperature is 10 degree to 40 degree, then temperature is more than 40 degree and needs to cool, and now the first threshold temperature is set
It is set to 40 degree；If the testing standard of battery is that battery lifes or battery performance not temperature are influenceed more than 70 degree, can now incite somebody to action
3rd threshold temperature is set to 70 degree or slightly below 70 degree temperature, when reaching this threshold values, to pass through the fast prompt drop of air conditioner coolant
Temperature is quickly reduced to below the 3rd threshold temperature by the liquid of warm liquid cooling system, is prevented to infringement caused by electrokinetic cell.
Certainly, explanation only for example here, its standard operating temperature of actually distinct battery, maximum operation temperature and minimum work
Temperature is different and different according to battery size production technology, can specifically be set according to specific battery, only left exemplary here
Explanation.
This method also includes collection motor and the temperature data of control circuit；
Judge whether temperature is more than the 4th threshold temperature, if so, starting the second liquid cooling system (9) to electric motor and controller electricity
Road is cooled down, and the second electric water pump of control (10), fan (12) start work.Here according to the work of electric motor and controller circuit
The 4th threshold temperature is set as temperature, when temperature is more than threshold values, starts electric water pump to realize fluid-cooled electrical machine and its control
Circuit.4th threshold temperature can be set according to the upper limit of the operating temperature ratings of electric motor and controller circuit, ensure its work
When it is too high to make temperature, then reaching threshold temperature, start liquid cooling system.
