1. A method of providing heat to a catalyst of an after-treatment system for a vehicle comprising an engine, the after-treatment system being powered by a battery, the method comprising:
determining an operational parameter of the battery;
predicting an activation of the engine based on determining that the operational parameter is approaching a first threshold and a torque demand, wherein the first threshold indicates a level at which the engine will be activated to charge the battery; and
providing heat to the catalyst of the after-treatment system in response to the battery operational parameter reaching a second threshold, wherein the second threshold is set at a level higher than the first threshold, and wherein the catalyst is activated before the operational parameter reaches the first threshold.
