The invention discloses a monitoring system for a power lithium battery of a new energy automobile, and relates to the technical field of new energy. Acquiring temperature data of the lithium battery through a temperature acquisition module; the data acquisition module acquires equipment parameters of the lithium battery; the data processing module compares the temperature data with a temperature threshold value to obtain an overtemperature signal; after the safety alarm module receives the overtemperature signal, an alarm device in the automobile is controlled to carry out overtemperature broadcasting, and a driver is reminded; after the control module receives the overtemperature signal, an overheat protection function is started, and the lithium battery is controlled to stop working; the data processing module calculates and obtains equipment indexes according to the equipment parameters; obtaining a prediction label through the equipment index and the temperature prediction model; the prediction label is identified, and when the prediction label is identified as a temperature rise trend, the data processing module generates a temperature reduction instruction; after the control module receives the cooling instruction, the discharge current of the lithium battery is reduced; and stable operation of the battery and improvement of the efficiency of the whole system are facilitated.
