Abstract: Starting from the causes and effects of static power consumption of commercial vehicles, the static power consumption of the whole vehicle is controlled by controlling the static current of the whole vehicle. How to effectively control the static power consumption of the whole vehicle is studied from the static current test, symmetry analysis, power distribution and other aspects. The methods to control static power consumption in two stages of design and trial production are summarized. In the whole vehicle design stage, according to the use scenario of electrical appliances, the power distribution is designed and the static current index of each component is formulated. Test and verify the components in the trial production stage, and control the static current of the components through the optimization control strategy to control the static power consumption of the whole vehicle.

Key words: Static power consumption; Symmetry analysis; Power distribution
