specific Embodiment approach 1
[0042] Specific implementation mode 1, the implementation process of the method for real-time prediction of battery internal temperature in this implementation mode is as follows:
[0043] Step 1. Establish a battery heat balance model according to the heat balance of the battery core-shell and the heat balance of the battery shell-outside:
[0044] Battery core-case battery thermal balance:
[0045] Battery case-external battery heat balance:
[0046] The specific heat capacities of the battery core and shell are C c and C s , the thermal resistance coefficient between the battery core and the shell is R c , the thermal resistance coefficient between the case and the outside air is R u , OCV is the corresponding relationship curve between the open circuit voltage and SOC obtained when the battery is left standing for a long time, V t is the battery terminal voltage; I t is the battery operating current, T f,t represents the external temperature at time t, T c,t Re...
