the second relay is a normally open four-pin relay, one contact terminal of the second relay is connected with the second storage battery pack, the other contact terminal of the second relay is connected with the generator or the high-low voltage direct current conversion power supply, and the second relay is in signal connection with the controller;
the third relay is a normally open four-pin relay, one contact terminal of the third relay is connected with the second storage battery pack, the other contact terminal of the third relay is connected with an additional part to be powered, and the third relay is in signal connection with the controller;
the fourth relay is a normally open four-pin relay, one contact terminal of the fourth relay is connected with the first storage battery pack, the other contact terminal of the fourth relay is connected with an additional part to be powered, and the fourth relay is in signal connection with the controller;
the controller outputs a closing signal to the third relay after receiving a signal sent by the automatic driving change-over switch for closing the automatic driving change-over switch; comparing the detected current voltage of the second storage battery pack with a preset voltage threshold, and if the voltage of the second storage battery pack is lower than the preset voltage threshold, outputting a closing signal to the second relay and outputting a closing signal to the fourth relay; after detecting that the current flows in the second relay and the fourth relay, outputting a disconnection signal to the third relay and outputting a disconnection signal to the first relay; comparing the detected current voltage of the first storage battery pack with a preset voltage threshold, and if the voltage of the first storage battery pack is lower than the preset voltage threshold, outputting a closing signal to the first relay and outputting a closing signal to the third relay; after detecting that current flows in the first relay and the third relay, outputting a disconnection signal to the fourth relay and outputting a disconnection signal to the second relay; and if the signal sent by the automatic driving change-over switch for switching off the automatic driving change-over switch is received, a switching-off signal is output to the third relay and the fourth relay.
7. The control system according to claim 6, wherein the first battery pack and the second battery pack are each composed of one vehicle battery.
8. The control system according to claim 6, wherein the first battery pack and the second battery pack are each composed of a plurality of vehicle batteries.
9. A vehicle, characterized by comprising a control system according to any one of claims 6 to 8, and at least one additional component to be powered, wherein the additional power supply of the additional component to be powered is managed and controlled by the control system.
