And part a.3.6: the power supply control device judges whether the vehicle is ready by measuring the voltage value of the detection point 1. When the peak voltage of the detection point 1 is the voltage value corresponding to the state 3 in the table a.2, the power supply control device makes the ac power supply loop conductive by closing the contactors K1 and K2.
Therefore, when the control switch S2 is in the closed state, the contactors K1 and K2 can be closed to conduct the AC power supply loop.
It is also described in the standard that the power supply devices outside the charging mode 2 and the charging mode 3 start to output alternating current to the vehicle-mounted charger after detecting that the back-end switch S2 is closed, and then each controller can perform power-on operation, wherein the power-on operation includes a battery management system, but the switch S2 is inside the battery management system, and the battery management system must be powered on to close the switch S2 first, so that the contradiction is caused.

2. This problem does not exist by having the S2 switch normally closed. However, this method cannot disconnect the ac power supply output by determining the disconnection of S2 when the charging is completed, and there is a certain safety hazard.
