description The invention relates to the field of batteries, and discloses a battery pack thermal simulation modeling method and device based on actual discharge working conditions. In the method, for each simulation moment in the simulation process, the following operations are executed: battery state parameters and output power of a to-be-simulated battery pack at the current simulation moment are obtained, the battery state parameters comprise the state of charge, the temperature and the voltage, and the voltage is searched from a mapping relation table of the voltage of the battery pack and the state of charge and the temperature; calculating the current of the battery pack at the current simulation moment according to the voltage and the output power at the current simulation moment; calculating the internal power loss of the battery pack at the current simulation moment according to the current; and inputting the internal power loss into a simulation model for simulation iteration so as to predict the state of char
