1. A charging apparatus, comprising:
a charger for inductively charging a separate, mobile apparatus;
a coolant flow path for providing a flow path for a phase-change cooling fluid to an interface with the mobile apparatus so as to enable cooling of, at least part of, the mobile apparatus when the mobile apparatus is being inductively charged by the charger;
wick structures in the coolant flow path, the wick structures enabling the phase-change cooling fluid to be transported via capillary action; and
an evaporator for enabling evaporation of the phase-change cooling fluid, wherein the evaporator is provided at the interface with the mobile apparatus so as to enable cooling of, at least part of, the mobile apparatus.
