When the battery needs to be heated, turning on both the first one-way branch and the first earth one-way branch, such as suspending heating, may choose to turn off one or both of the first one-way branch and the second one-way branch When the heating is not required, both the first one-way branch and the second one-way branch can be turned off. Preferably, both the first unidirectional branch and the second unidirectional branch are controllable by the switch control module 1 , such that energy forward flow and reverse flow can be flexibly achieved. As another embodiment of the switching device 1, as shown in FIG. 3, the switching device 1 may include a second bidirectional switch K4 and a third bidirectional switch K5, and the second bidirectional switch K4 and the third bidirectional switch K5 are connected in reverse series with each other. To form the first one-way branch and the second one-way branch, the switch control module 100 is respectively connected to the first bidirectional switch K4 and the third bidirectional switch K5 for controlling the second bidirectional switch K4 and the third The bidirectional switch K5 is turned on and off to control the on and off of the first one-way branch and the second one-way branch.

Features. Preferably, the switching device 1 may further comprise a resistor associated with the first one-way branch and/or the •= one-way branch for reducing the current of the battery E heating circuit 'avoiding the loop causing excessive current to the battery E Cause damage. For example, a resistor R6 connected in series with the second bidirectional switch K4 and the third bidirectional switch K5 may be added to the switching device 1 shown in the φ 帛 3 diagram to obtain another implementation of the switch as shown in FIG. . Also shown in Fig. 6 is an embodiment of the switching device i which is obtained by series-connecting a resistor R2 and a resistor ^3 on two unidirectional branches in the switching device shown in Fig. 4. Due to the presence of the first current-memory element L1 in the loop, turning off the switching device 1' when the current is present in the loop may cause the first current-memory element L1 in the loop to generate a large induced voltage, which may be damaged.
