Technical solutions provide a model-based cooling control of an EV battery during a direct current fast charging (DCFC) event. The technical solutions can include a processor coupled with memory to identify a state of charge (SOC), a temperature threshold and a gradient threshold for a difference in temperature between at least two cells of an EV battery. The processor can determine an amount of cooling to apply during a charge of the battery based at least on the SOC, the temperature of the battery and the difference in temperature input into a model for cooling the battery to maintain the temperature below the temperature threshold and the difference in temperature below the gradient threshold. The processor can provide to the battery the amount of cooling determined by the model to maintain the temperature below the temperature threshold and the difference in temperature below the gradient threshold during the charge.
