The invention relates to the technical field of new energy automobiles, and provides an automobile power battery voltage abnormity processing method and device and a new energy automobile. The method comprises the following steps: acquiring the voltage of a single battery in the power battery; detecting the current working state of the power battery, wherein the working state of the power battery comprises a discharging state and a charging state; based on the working state of the power battery, target judgment conditions of battery voltage abnormity are determined, each working state of the power battery corresponds to at least one voltage abnormity judgment condition, and the voltage abnormity judgment condition is a voltage threshold range determined based on the current working state of the power battery and the working scene temperature; judging whether the voltage of the single battery meets a target judgment condition or not; and under the condition that the voltage of the single battery meets the target judgment condition, executing at least one response measure that the voltage meets the target judgment condition. According to the invention, the abnormal voltage of the power battery can be detected and processed more reasonably, and the safety of the battery and a vehicle is improved.
