Abstract
This application relates to the technical field of electric vehicles, and in particular, to charging systems and methods. An example charging system includes: a low-voltage battery capable of supplying power to a low-voltage electrical device of a vehicle; a power battery module; a direct current-to-direct current (DC-DC) converter capable of receiving a voltage supplied by the power battery module in response to at least that a positive relay and a negative relay of the power battery module are closed, and converting the voltage into a charging voltage of the low-voltage battery to charge the low-voltage battery; and a DC-DC controller electrically connected to the low-voltage battery and capable of monitoring a voltage of the low-voltage battery in response to at least that the vehicle is in a dormant state.
