Embodiment 1
[0042] Figure 1-4 Shown is an embodiment of the battery module thermal management device of the present invention, the battery module thermal management device includes a plurality of deflectors 2, a plurality of thermal pads 1, a driving mechanism, a temperature sensor 3, a control A device 5 and a box body 7; there are a plurality of single cells 4 in the box body 7; the deflectors 2 are respectively located at the bottom and sides of the single cells 4; the driving mechanism is connected with the flow deflectors 2 to drive The deflector 2 is attached or separated from the bottom and / or side of the single battery 4; the temperature sensor 3 is used to collect the temperature signal at the bottom and side of each single battery 4; the controller 5 is connected with the temperature sensor respectively 3 is connected to the driving mechanism; the temperature signal collected by the temperature sensor 3 is transmitted to the controller 5, and the controller 5 controls the drivi...
Embodiment 2
[0048] A vehicle, comprising the battery module thermal management device described in Embodiment 1. Have the beneficial effect of embodiment 1, do not repeat them here.
Embodiment 3
[0050] A control method of the battery module thermal management device according to Embodiment 1, comprising the following steps:
[0051] The temperature sensor 3 is used to collect temperature signals at the bottom and sides of each single battery 4 and transmits them to the controller 5; the controller 5 controls the drive mechanism according to the temperature signal so that the deflector 2 is connected to the bottom of the single battery 4. and / or side fit or detach.
[0052] Figure 5As shown, the steps of the controller 5 controlling the drive mechanism according to the temperature signal are specifically:
[0053] The optimal working temperature of the single battery 4 is T, and the bottom temperature of the single battery 4 is T 1 , the side temperature of the single battery 4 is T 2 ;
[0054] When the battery pack is working, the controller 5 detects T 1 >T 2 > T, control the driving mechanism to make the bottom deflector 2 and the side deflector 2 stick to t...
