The invention provides a method and system for preventing power shortage of a vehicle and the vehicle. The method comprises the steps that when the electric quantity of a lithium battery of a vehicle is consumed to a system set value, a storage battery controller controls and sends a battery lock electric signal to a vehicle body domain controller; after the battery lock electric signal is received, the vehicle body domain controller sends a control instruction for allowing the storage battery controller to cut off the whole vehicle power supply to the storage battery controller; and after the control instruction is received, the storage battery controller controls to cut off the power supply of the whole vehicle. According to the invention, the electricity shortage phenomenon of the vehicle can be greatly reduced.
