Embodiment Construction
[0026] The present invention is further described below in conjunction with accompanying drawing and embodiment:
[0027] Such as figure 1 As shown, an embodiment of the present invention provides a control method for a two-way on-board charger, including the following steps:
[0028] Step S1: In the charging mode, the PFC control module 10 identifies the input mode of the system by detecting the input voltage of the three-phase input terminal, and notifies the vehicle controller 13 of the input mode through the LLC control module 11 and the application layer interface module 12 . If AC voltage is detected on the first phase, but no AC voltage is detected on the second and third phases, it is judged that the input mode is single-phase input mode. If AC voltage is detected on the first phase, the second phase and the third phase , then it is judged that the input mode is a three-phase input mode. The PFC control module 10 informs the LLC control module 11 of the input mode th...
