The invention provides a vehicle battery thermal runaway early warning method, device and equipment and a storage medium, and the method comprises the steps: obtaining the statistical information of a historical temperature sensing device under a preset control working condition, and determining a target high-temperature sensing device and a target low-temperature sensing device according to the statistical information of the historical temperature sensing device; the method comprises the following steps: determining a target high-temperature sensing device and a target low-temperature sensing device as early-warning control temperature sensors, calibrating the early-warning control temperature sensors, responding to a battery temperature detection request, determining temperature parameters of the calibrated early-warning control temperature sensors, comparing the temperature parameters of the early-warning control temperature sensors with a preset thermal runaway judgment threshold interval, and determining a thermal runaway judgment result. Obtaining a thermal runaway comparison result to execute a corresponding early warning strategy; according to the method, the early-warning control temperature sensor is determined and calibrated in the historical statistical information, and thermal runaway early warning is performed according to the early-warning control temperature sensor, so that the thermal runaway judgment time is shortened, the precursor signal of thermal runaway is recognized in time, and the delay of early-warning response time is avoided.
