The invention relates to the technical field of automobile battery monitoring, in particular to a battery temperature early warning method for a vehicle-mounted terminal of an intelligent networked automobile. The method comprises the following steps: acquiring a to-be-analyzed temperature sequence and a voltage sequence of a battery when an automobile runs; obtaining a status bit of each piece of voltage data of the voltage sequence, forming a status bit sequence, and segmenting the status bit sequence so as to achieve the purpose of segmenting the temperature sequence to be analyzed; establishing a window by taking one piece of temperature data as a center to calculate an interference coefficient of the temperature data; according to a difference value and a slope value between every two adjacent data in the to-be-analyzed temperature sequence, obtaining an intensity coefficient of each piece of temperature data in a sharp rising trend, and further obtaining a prediction weight of the temperature data; and based on the prediction weight of each piece of temperature data, using an ARIMA algorithm to obtain a prediction temperature at a to-be-predicted moment, and carrying out vehicle battery temperature early warning. According to the invention, the accuracy of vehicle battery temperature prediction can be improved, and real-time early warning of the battery temperature can be carried out.
