Beschreibung
Zusammenfassung:	The invention provides a controlling method of a voltage setting point of a direct-current high-voltage and low-voltage converter, belonging to the technical field of hybrid electric vehicles. The controlling method is used for the direct-current high-voltage and low-voltage converter and is used for setting the voltage setting point of the direct-current high-voltage and low-voltage converter on the basis of a charge state of a low-voltage battery, wherein the voltage setting point descends along with the rise of the charge state. The controlling method disclosed by the invention can ensure that electric energy supplied to the low-voltage battery by a high-voltage power battery is in a better state, and the energy utilization rate of the high-voltage power battery is increased.
