1. A thermal management system, including:
a vapor chamber comprising a housing and a working fluid;
a battery pack comprising a plurality of battery cells, each of the plurality of battery cells disposed partially within the vapor chamber,
wherein the working fluid changes phase within the vapor chamber in order to carry heat away from the plurality of battery cells;
a heat pump coupled to the vapor chamber via a cold plate;
a condensation chamber coupled to the cold plate; and
a capillary tube having an intake end at a first location within the vapor chamber and a return end at a second, different location within the vapor chamber,
wherein the capillary tube passes at least partially through the condensation chamber.
