Close heater, and perform next step；If Current Temperatures is higher than start-up temperature, then perform next step detection；
Liquid level information in step 3, collection fluid infusion case；
If liquid level (used fluid infusion before this explanation, following of automobile radiators less than or equal to setting value in current fluid infusion case
Loop systems there may be leakage), then perform step 7, and persistently report to the police, if liquid level is more than setting value in current fluid infusion case, then hold
Go next step；
Temperature and liquid level information in step 4, system Real-time Collection battery case 1；This is the normalization monitoring under work condition state,
Current temperature value can be the meansigma methods of each temperature sensor 8 temperature；
If Current Temperatures is higher than the temperature upper limit set, then open manifold valve, heat dissipation pump and liquid valve；If Current Temperatures is low
Limit at a temperature of setting, then close manifold valve, heat dissipation pump and liquid valve；Described temperature upper limit is more than lowest temperature, it is to avoid dissipate
Heat pump is frequently opened；
If present battery case 1 level value is less than the safety levels value set, the most persistently reports to the police and perform step 6；
Step 5, manually close closed system (driver's power-off), level value in record present battery case 1, and close manifold valve,
Heat dissipation pump and liquid valve, or keep manifold valve, heat dissipation pump and the closed mode of liquid valve, terminate (performing the most still further below)；
Step 6, closedown manifold valve, heat dissipation pump and liquid valve, open valve in liquid supplementation pipe big to present battery case 1 level value
In the safety levels value set；
Liquid level information and temperature information in step 7, system Real-time Collection battery case 1；Current temperature value can be each temperature
The meansigma methods of degree sensor 8 temperature
If present battery case 1 level value is less than the safety levels value set, then there is leakage in explanation battery case 1, then continue
Reporting to the police and after the delay adjustments time, stop battery case 1 and outwards power, delay time is to allow driver by vehicle parking in safety
Position, terminates (performing the most still further below)；
If Current Temperatures is higher than the temperature upper limit set, then open air conditioning for automobiles, the valve of condensation pipe inlet and outlet,
And the valve on ON cycle pump and circulating pump pipeline；
Step 8, manually close closed system (driver's power-off), level value in record present battery case 1, and closing automobile empty
