1. A method for thermal management performed by a controller of an energy storage system, the energy storage system including at least a first battery module, a second battery module, a first battery management system (BMS) node, and a second BMS node, the first BMS node being configured to control operation of the first battery module, and the second BMS node being configured to control operation of the second battery module, the method comprising:
setting a desired temperature profile of the first battery module according to one or more of a degradation vector of the first battery module, a state of health vector of the first battery module, and a state of safety vector of the first battery module, the desired temperature profile of the first battery module representing desired temperature of the first battery module over a duration of time;
determining a first temperature profile difference representing a difference between an actual temperature profile of the first battery module and the desired temperature profile of the first battery module;
determining a first operation adjustment representing a desired change in operation of the first battery module for decreasing the first temperature profile difference; and
controlling the first BMS node to change operation of the first battery module according to the first operation adjustment.
