The embodiment of the invention provides a battery pack heating control device and method and a vehicle, and belongs to the technical field of battery pack heating. The device comprises a one-way pre-charging module and a control module, the one-way pre-charging module is connected with a normally open contact of a main positive contactor in parallel, and the control module is used for controlling the one-way pre-charging module when a battery pack is heated through a charging pile. Controlling a normally open contact of the main positive contactor to be disconnected, controlling a normally open contact of the main negative contactor to be connected with the one-way pre-charging module, and enabling the current flowing out of the charging pile not to flow to a battery pack through the one-way pre-charging module; therefore, the charging pile only supplies power to the heating module of the battery pack and does not charge the battery pack. When the battery pack is heated through the charging pile, the charging pile only supplies power to the heating module of the battery pack and does not charge the battery pack, and in addition, the battery pack can be prevented from being discharged in the heating process of the battery pack.
本发明实施例提供一种电池包加热控制装置、方法及车辆,属于电池包加热技术领域。所述装置包括单向预充电模块和控制模块,所述单向预充电模块与主正接触器的常开触头并联,所述控制模块用于:在通过充电桩向电池包加热时,控制所述主正接触器的常开触头断开连接、控制主负接触器的常开触头和所述单向预充电模块接通,其中所述单向预充电模块使得从充电桩流出的电流不能流向电池包,从而使得所述充电桩仅对所述电池包的加热模块供电而不会对所述电池包充电。其能够实现在通过充电桩向电池包加热时,充电桩仅对所述电池包的加热模块供电而不会对所述电池包充电,另外能够实现电池包加热过程中避免电池包放电。
