TEMPERATURE MANAGEMENT FOR INDUCTIVE CHARGING SYSTEMS
First Claim
1. A charging apparatus comprising:
- a housing defining an interface surface;
a power source within the housing;
a power-transferring coil coupled to the power source and positioned below the interface surface;
a thermal mass within the housing and spaced apart from the interface surface; and
a thermal path configured to conduct heat from the interface surface to the thermal mass.

Abstract
A thermal management system for an electromagnetic induction-power transfer system. The system may include a charging apparatus including a housing that defines an interface surface. An accessory or induction-power consuming apparatus may be positioned proximate to the interface surface. The housing of the charging apparatus may include a power source and a power-transferring coil coupled to the power source and positioned below the interface surface. A thermal mass may be positioned within the housing and spaced apart from the interface surface. The housing may include a thermal path that is configured to conduct heat from the interface surface to the thermal mass.

19. A method for managing a temperature of an induction power-transferring apparatus, the method comprising:
-
receiving, at an interface surface of the induction power-transferring apparatus, heat from an accessory positioned proximate to the interface surface; directing the heat received at the interface surface through at least one thermal path to a thermal mass; and directing heat within the thermal mass to a cable for connecting to a power outlet, the cable comprising a thermally conductive layer. - View Dependent Claims (20, 21, 22, 23)
