Degree threshold value, then go to step 4；If the real-time temperature values of described power battery pack is more than or equal to described minimum
Temperature threshold and less than or equal to described maximum temperature threshold, then go to step 5；
Step 3: described controller is by controlling the unlatching shape of described first triple valve and described second triple valve
State, starts water pump simultaneously, heats to described power battery pack, until institute controlling described heat cycles water route
State the real-time temperature values of the described power battery pack that temperature sensor records more than or equal to described minimum temperature
Threshold value and less than or equal to described maximum temperature threshold, when the described power electric that described temperature sensor records
The real-time temperature values of pond group is more than or equal to described minimum temperature threshold and less than or equal to described maximum temperature
During degree threshold value, go to step 5；
Step 4: described controller is by controlling the unlatching shape of described first triple valve and described second triple valve
State, starts water pump simultaneously, lowers the temperature to described power battery pack, until institute controlling described heat radiation circulation waterway
State the real-time temperature values of the described power battery pack that temperature sensor records more than or equal to described minimum temperature
Threshold value and less than or equal to described maximum temperature threshold, when the described power electric that described temperature sensor records
The real-time temperature values of pond group is more than or equal to described minimum temperature threshold and less than or equal to described maximum temperature
During degree threshold value, go to step 5；
Step 5: described controller controls described water pump and cuts out, and controls described first triple valve and second simultaneously
Triple valve is closed.
