1. A method for determining a charging profile from a plurality of charging profiles for a current charging process for charging an electrical energy storage unit, the method comprising:
determining a current state of the energy storage unit;
determining an application context that characterizes the current charging process;
determining the charging profile from the plurality of charging profiles based on the current state of the energy storage unit and based on the application context; and
charging the energy storage unit based on the determined charging profile,
wherein the current state of the energy storage unit comprises a current temperature spread within one cell or between different cells of the energy storage unit, and the charging profile is determined from the plurality of charging profiles at least partially based on the current temperature spread.
