A new energy vehicle fire early warning method and a controller are applied to the field of fire prevention and control, and the method comprises the following steps: monitoring the temperature change of a battery pack in a new energy vehicle in real time to obtain a temperature data sequence; analyzing the temperature data sequence through a preset temperature detection model to obtain a target temperature change trend; when it is determined that the target temperature change trend is inconsistent with the standard temperature change trend during charging and discharging of the battery pack, the air temperature and the gas concentration collected by a sensor are obtained; inputting the air temperature and the gas concentration into a preset fire behavior prediction model to obtain a fire behavior prediction probability; determining whether the new energy vehicle has a fire risk according to the fire prediction probability; and triggering a preset alarm device under the condition of determining that the new energy automobile has a fire risk according to the fire behavior prediction probability. The method has the effects of predicting the occurrence of the fire in time and improving the accuracy and timeliness of fire early warning of the new energy automobile.
