The battery temperature of the sides interface M is relatively low.
Temperature difference detecting element persistently detects between the battery of the first sides coolant connection K and the second sides coolant connection M
Battery temperature it is poor (for example, battery of the detection closest to the first coolant connection K and the battery closest to the second coolant connection
Between battery temperature it is poor).Wherein, which is construed as absolute value, i.e., (the first sides coolant connection K
Battery between the sides battery temperature the-the second coolant connection M) absolute value.

When, coolant liquid is heated in ptc heater first, is then flowed through the second coolant connection M of battery pack, is passed through battery
First coolant connection K of group.That is the second sides coolant connection M battery of battery pack is heated first, followed by battery
The battery of first sides coolant connection K of group is heated.After heating after a period of time, due to series pipe internal temperature
Inhomogeneities, after so running a period of time, the battery temperature difference of internal battery pack will reduce (i.e. the first sides coolant connection K
Battery temperature and the battery temperature of the second sides coolant connection M gradually approach), keep state shown in Fig. 2 to continue to run with.Then,
The temperature difference will become zero, i.e., the battery temperature of the first sides coolant connection K is identical as the battery temperature of the second sides coolant connection M,
This state is kept to continue to run at this time, the temperature difference will start from scratch increases that (battery temperature of the second sides coolant connection M is gradually opened again
Begin more than the battery temperature of the first sides coolant connection M), when the temperature difference reaches more than specified threshold a, then execute commutation behaviour
Make, and so on, until heat management system is closed.
