The invention provides a battery thermal management device, a vehicle and a battery heating method. The battery heat management device comprises a preheating branch circuit and a battery heat exchange branch circuit, and the preheating branch circuit is connected with the battery heat exchange branch circuit; the heat exchange medium flows through the preheating branch to perform preheating circulation, and the preheated heat exchange medium can enter the battery heat exchange branch to perform battery heating circulation so as to heat the battery. The circulation amount of the heat exchange medium in the loop can be increased through preheating circulation, the heating effect is further improved, due to the fact that the influence of the battery temperature on the charging current is large, the heating rate of the battery can be increased through improvement of the heating performance, and therefore the charging duration is shortened.

    本申请提供一种电池热管理装置、车辆和电池加热方法。其中,电池热管理装置包括预热支路和电池换热支路,预热支路与电池换热支路相连;换热介质流经预热支路进行预热循环,预热后的换热介质能够进入电池换热支路进行电池加热循环以加热电池。预热循环可以增加回路中的换热介质的循环量,进一步提升加热效果,由于电池温度对充电电流影响较大,加热性能的提升能够提升电池的升温速率,从而缩短充电时长。
