Beschreibung
Zusammenfassung:	The invention discloses a low-voltage power supply method for a new energy automobile, and the main design concept of the method is that a low-voltage electric appliance is divided into a first electric load and a second electric load, the first electric load is connected with a DCDC in parallel, and the second electric load is connected with a storage battery in parallel, so that the second electric load is provided with two power supplies; the power demand is determined in real time according to the starting condition of the low-voltage electric appliance, and the working power combination of the DCDC is actively controlled based on the power demand and the state of the storage battery, so that the DCDC is kept in a high-efficiency working condition state. The reasonable low-voltage power supply mode provided by the invention can be suitable for new energy passenger vehicles and commercial vehicles configured with DCDC, the loss of the DCDC can be effectively reduced and the endurance performance of the who
